Large-scale, continuous, low-cost, and low-energy recycling and reuse technologies are urgently needed to achieve sustainable, green, and low-carbon development of the industry.
[0059] In view of this, refer to Figure 1 and Figure 2 As shown, the waste recycling and processing equipment provided by the present application heats the fiber reinforced composite material waste and provides oxygen-free protection through superheated steam, thereby ensuring that the fiber reinforced composite material waste can be effectively thermally cracked, and the cracking gas generated after thermal cracking can be fully burned in the thermal energy conversion combustion furnace 3 to generate a clean heat source.

[0060] Implementation Method 1
[0061] The present application provides a waste recycling and processing device for fiber-reinforced composite waste, the waste recycling and processing device comprising:
[0062] The regeneration treatment furnace 1 comprises a treatment furnace chamber, and the treatment furnace chamber is used to accommodate the fiber reinforced composite material waste;
[0063] The superheated steam generator 2 is able to communicate with the processing furnace chamber and deliver superheated steam into the processing furnace chamber;

The heat energy conversion combustion furnace 3 can ignite the cracking gas from the processing furnace chamber to form non-toxic hot gas, and can transport the non-toxic hot gas to the superheated steam generator 2 and / or the regeneration processing furnace 1.
[0065] The waste regeneration equipment provided by the present application is used for fiber reinforced composite waste. The waste regeneration and treatment equipment includes a regeneration treatment furnace 1, a superheated steam generator 2 and a heat conversion combustion furnace 3. The regeneration treatment furnace 1 includes a treatment furnace chamber, and the treatment furnace chamber is used to accommodate fiber reinforced composite waste. The fiber reinforced composite waste is heated in the treatment furnace chamber, and the resin matrix and the fiber are separated. The resin matrix is vaporized and decomposed to produce cracking gas, and the cracking gas is transported to the heat conversion combustion furnace 3 for full combustion, thereby obtaining a clean heat source. The superheated steam generator 2 can be connected to the treatment furnace chamber and transport superheated steam to the treatment furnace chamber; the superheated steam generated by the superheated steam generator 2 can be used as a protective gas, which can isolate oxygen and prevent the resin in the carbon fiber reinforced composite waste from reacting with oxygen to produce harmful gases. At the same time, the superheated steam can also be used as a heat transfer medium to separate the carbon fiber and the matrix resin in the carbon fiber reinforced composite waste, so as to obtain clean, carbon-free, and regenerated carbon fiber with a strength of more than 90% of the original carbon fiber and excellent performance. The heat energy conversion combustion furnace 3 is connected to the processing furnace chamber and the superheated steam generator 2 respectively. The heat energy conversion combustion furnace 3 can ignite the cracking gas from the processing furnace chamber to form non-toxic hot gas, and can transport the non-toxic hot gas to the superheated steam generator 2 and / or the regeneration processing furnace 1.
[0066] The waste recycling and processing equipment provided in the present application heats the fiber-reinforced composite waste and provides oxygen-free protection through superheated steam, thereby ensuring that the fiber-reinforced composite waste can be effectively thermally cracked, and the cracking gas generated after thermal cracking can be fully burned in the thermal energy conversion combustion furnace 3 to generate a clean heat source.

At the same time, the recovery process has the characteristics of zero exhaust emissions and zero pollution.
[0067] Among them, the clean heat source generated in the heat energy conversion combustion furnace 3 is transported to the regeneration treatment furnace 1, such as Figure 2 As shown, it can be used as a heating source and can also be used to remove carbon deposits on the surface of the carbon fiber, so that the heat source recovered by the thermal energy conversion combustion furnace 3 can play a greater role and further reduce costs.
[0068] Implementation Method 2
[0069] like Figure 3As shown, one embodiment of the present application provides a regeneration processing furnace 1 for fiber reinforced composite material waste 122, the regeneration processing furnace 1 includes a processing furnace shell 110, a processing furnace chamber 111, an air intake assembly 114, a first exhaust assembly 115, a second exhaust assembly 116 and a heating device 117, the processing furnace chamber 111 is arranged in the processing furnace shell 110, and the processing furnace chamber 111 is used to accommodate the fiber reinforced composite material waste 122; the air intake assembly 114 is arranged on the processing furnace shell 110 and communicated with the processing furnace chamber 111, and the air intake assembly 114 is used to input superheated steam or hot air; the first exhaust assembly 115 is arranged on the processing furnace shell 110 and communicated with the processing furnace chamber 111; the second exhaust assembly 116 is arranged on the processing furnace shell 110 and communicated with the processing furnace chamber 111, and the second exhaust assembly 116 is used to discharge cracking gas; the heating device 117 is arranged on the processing furnace shell 110, and the heating device 117 and / or superheated steam can heat the interior of the processing furnace chamber 111.
[0070] The regeneration processing furnace 1 of the present application includes a processing furnace shell 110, a processing furnace chamber 111, an air intake assembly 114, a first exhaust assembly 115, a second exhaust assembly 116 and a heating device 117. The processing furnace chamber 111 is arranged inside the processing furnace shell 110. The processing furnace chamber 111 is used to provide a combustion space. The fiber reinforced composite material waste 122 is placed in the processing furnace chamber 111, and the recycling processing is completed in the processing furnace chamber 111.
[0071] Among them, the treatment furnace shell 110 is provided with an air intake component 114, and the air intake component 114 is connected to the treatment furnace chamber 111. When the regeneration treatment furnace 1 is in different working stages, the air intake component 114 can selectively introduce superheated steam or hot air. The regeneration treatment furnace 1 includes a first stage and a second stage. In the first stage, superheated steam is transported to the treatment furnace chamber 111 through the air intake component 114. The superheated steam can be used as a heating heat source and an oxygen-free protection medium, and can be used for oxygen-free protection and heating of the fiber-reinforced composite waste 122 located in the treatment furnace chamber 111, so that the resin matrix in the fiber-reinforced composite waste 122 can be completely gasified, and the separation between the fiber and the matrix resin can be achieved. In the second stage, the input of superheated steam is stopped, and hot air is input into the treatment furnace chamber 111. The carbon deposit on the surface of the gasified fiber is completely removed by inputting a high-temperature air heat flow, so that there is no carbon deposit residue on the recycled regenerated fiber, the surface is clean, and the strength of the recycled regenerated carbon fiber can reach more than 90% of the original carbon fiber. It is worth noting that, in the second stage, the source of hot air can be provided by a separate hot air conveying device 4 or by a heat energy conversion combustion furnace 33 .
[0072] Among them, a first exhaust component 115 and a second exhaust component 116 are also provided on the treatment furnace shell 110. The first exhaust component 115 is used to ensure the pressure balance in the treatment furnace chamber 111 and to ensure the circulation of other gases in the treatment furnace chamber 111 except the cracking gas. The second exhaust component 116 is used to discharge the cracking gas to the outside. The cracking gas refers to the combustible organic small molecule gas produced by the decomposition of the resin matrix in the fiber reinforced composite material waste 122, that is, the cracking gas is a toxic gas. Of course, the discharge of the cracking gas through the second exhaust component 116 here refers to the discharge relative to the treatment furnace chamber 111. The cracking gas will be discharged to a predetermined position, such as in the thermal energy conversion combustion furnace 33, and the toxic cracking gas can be converted into clean high-temperature hot gas, which can be used to provide a heat source for the regeneration treatment furnace 1. The cracking gas will not be discharged to the external environment and will not cause environmental pollution. That is to say, the toxic gases produced by the combustion and decomposition of the fiber-reinforced composite material waste 122 in the processing furnace chamber 111 will be guided out separately from the second exhaust component 116, which is independent of the first exhaust component 115 used to maintain the pressure balance in the cranial cavity, which is convenient for precise control and can also simplify the subsequent treatment of the toxic gases.
[0073] In the present application, a heating device 117 is also provided on the treatment furnace shell 110 of the regeneration treatment furnace 1, and the heating device 117 can also heat the interior of the treatment furnace chamber 111. The superheated steam can not only heat the interior of the treatment furnace chamber 111, but also serve as a protective atmosphere during the thermal decomposition process of the fiber reinforced composite material waste 122, which can effectively reduce energy consumption and ensure the efficiency of thermal decomposition, so that the fibers can be well collected and the recovery rate is improved.
[0074] It is worth noting that the generation of superheated steam can rely on the superheated steam generator 22, and the heat source converted from the cracked gas discharged from the second exhaust component 116 can be used to heat the superheated steam generator 22 to facilitate the generation of superheated steam.
[0075] Optionally, the regeneration processing furnace 1 further includes a control component 118 , which is disposed on the processing furnace shell 110 , and is used to adjust the internal temperature of the processing furnace chamber 111 and / or the internal pressure of the processing furnace chamber 111 .
[0076] In an embodiment of the present application, the regeneration processing furnace 1 also includes a control component 118, which is arranged on the processing furnace shell 110. The control component 118 is used to adjust the internal temperature of the processing furnace chamber 111, so as to ensure that the fiber-reinforced composite material waste 122 located inside the processing furnace chamber 111 can be separated from the resin matrix at a suitable temperature to achieve the recovery of the regenerated fiber.
[0077] Specifically, in the first stage, when the regeneration furnace 1 is used for the fiber-reinforced composite waste 122, the superheated steam introduced into the treatment furnace chamber 111 of the regeneration furnace 1 is a superheated steam of 400°C to 700°C at a low oxygen and normal pressure, and the superheated steam performs oxygen-free protection and heating on the carbon fiber-reinforced composite material for 1 to 6 hours, so that the resin matrix in the fiber-reinforced composite waste 122 can be completely gasified, and the fiber filaments and the resin matrix in the carbon fiber-reinforced composite waste 122 can be separated. Among them, the fiber includes carbon fiber.
[0078] In the second stage, the temperature in the processing furnace chamber 111 can be controlled at 400°C to 500°C through the control component 118, and hot compressed air is input. The carbon deposits on the surface of the gasified fiber-reinforced composite material waste 122 can be completely removed through the high-temperature air heat flow. The recycled regenerated carbon fiber has no carbon deposit residue and a clean surface. The strength of the recycled regenerated carbon fiber can reach more than 90% of that of the original carbon fiber.
[0079] That is to say, during the operation of the regeneration processing furnace 1, the temperature and pressure inside it are not constant, but are adjusted according to different stages, and the control component 118 can ensure that the temperature and pressure inside the processing furnace chamber 111 are within a reasonable range, so that the recovery efficiency of carbon fiber in waste fiber reinforced composite materials is greatly improved.
[0080] Optionally, the regeneration processing furnace 1 also includes an inner shell 112, which is arranged inside the processing furnace shell 110, and the inner shell 112 has a processing furnace cavity 111. A heating chamber 113 that is not connected to the processing furnace cavity 111 is provided between the inner shell 112 and the processing furnace shell 110, and the heating device 117 is located in the heating chamber 113; the control component 118 includes a first temperature sensor and a second temperature sensor, the first temperature sensor is used to detect the temperature in the processing furnace cavity 111, and the second temperature sensor is used to detect the temperature in the heating chamber 113.
[0081] In an embodiment of the present application, the regeneration processing furnace 1 also includes an inner shell 112, which is arranged inside the processing furnace shell 110. It can be understood that the inner shell 112 is inserted into the processing furnace shell 110, and the inner shell 112 can form a processing furnace chamber 111, that is, the fiber reinforced composite material waste 122 is placed inside the inner shell 112, and there is a heating chamber 113 between the inner shell 112 and the processing furnace shell 110, that is, between the outer wall of the inner shell 112 and the inner wall of the processing furnace shell 110. The heating chamber 113 and the processing furnace chamber 111 are two relatively independent spaces, which are isolated from each other by the inner shell 112. The heating device 117 is arranged in the heating chamber 113, and the heating device 117 generates heat in the heating chamber 113. The heat will be transferred to the inside of the processing furnace chamber 111 through the inner shell 112, thereby achieving the purpose of heating the fiber reinforced composite material waste 122 inside the processing furnace chamber 111.
[0082] The control component 118 includes a first temperature sensor and a second temperature sensor. The first temperature sensor is used to detect the temperature in the processing furnace chamber 111. Specifically, the number of the first temperature sensors is 2, and the two first temperature sensors are respectively arranged on both sides of the inner shell 112. The second temperature sensor is used to detect the temperature of the heating chamber 113. Specifically, the number of the second temperature sensors is 2, and the two second temperature sensors are respectively arranged on the front and rear sides of the heating chamber 113, that is, the number of temperature sensors is 4 in total. Since the temperature in the processing furnace chamber 111 is also controlled by the heat provided by the heating chamber 113, the temperatures of the processing furnace chamber 111 and the heating chamber 113 are interrelated. In order to achieve accurate control of the temperature in the processing furnace chamber 111, the first temperature sensor and the second temperature sensor are used to detect the temperatures in the processing furnace chamber 111 and the heating chamber 113, respectively, to maximize the elimination of temperature inertia during the heating process, thereby achieving uniform distribution of temperature in the processing furnace chamber 111.
[0083] Optionally, the regeneration treatment furnace 1 further includes a supplementary heat air inlet, which is provided on the treatment furnace shell 110 and communicated with the heating chamber 113 .
[0084] In an embodiment of the present application, carbon fiber reinforced composite material waste 122 is burned in the processing furnace chamber 111, and the generated cracking gas is discharged to the thermal energy conversion combustion furnace 33 through the second exhaust assembly 116. The cracking gas is fully burned in the thermal energy conversion combustion furnace 33 and converted into very clean high-temperature hot gas. The clean high-temperature hot gas can enter the heating chamber 113 through the heat supplementary air inlet, thereby heating the interior of the processing furnace chamber 111, so that the heat energy generated by the cracking gas can be recycled, effectively reducing costs, which is in line with the development trend of green and environmental protection.
[0085] Implementation Method 3
[0086] The inventor of the present application discovered that Figure 3 As shown, when the sealing performance of the processing furnace chamber 111 and the sealing performance of the heating chamber 113 cannot be guaranteed, not only can the fiber reinforced composite material waste 122 in the processing furnace chamber 111 not be effectively thermally decomposed, but it may also cause the waste generated by the fiber reinforced composite material waste 122 during the cracking process to leak and cause environmental pollution.
[0087] To this end, an embodiment of the present application proposes a regeneration processing furnace 1, wherein a material port is provided on one side of a processing furnace shell 110; the regeneration processing furnace 1 also includes a furnace door 119 and a seal, wherein the furnace door 119 is movably provided on the processing furnace shell 110 to open and close the material port; the seal is provided on the furnace door 119, and when the furnace door 119 closes the material port, the seal is clamped between the furnace door 119 and the processing furnace shell 110.
[0088] In an embodiment of the present application, a material port is provided on one side of the treatment furnace shell 110, and the fiber reinforced composite waste 122 can be transported from the material port to the treatment furnace chamber 111 through a material cart 121. The regeneration treatment furnace 1 also includes a furnace door 119 and a seal. The furnace door 119 is movably arranged on the treatment furnace shell 110, and the furnace door 119 moves relative to the treatment furnace shell 110 to realize the opening or closing of the material port. Among them, the seal is arranged on the furnace door 119. When the furnace door 119 closes the material port, the seal is clamped between the furnace door 119 and the treatment furnace shell 110. The seal can effectively seal the gap between the furnace door 119 and the treatment furnace shell 110, so that during the operation of the regeneration treatment furnace 1, the gas in the cracking process will not leak outward along one side of the furnace door 119, thereby ensuring the safe use performance of the regeneration treatment furnace 1.
[0089] Optionally, the seal is a locking ring type sealing structure with excellent sealing performance.
[0090] Optionally, the regeneration furnace 1 further comprises a cooling component, which is disposed on one side of the seal. The cooling component can cool the seal to avoid damage to the seal due to excessive temperature.
[0091] Optionally, the cooling component is a water cooling component, which is low-cost and easy to implement.
[0092] It is worth noting that when the furnace door 119 is closed, the hydraulic system can be used to tightly press the furnace door 119 and the seal against the processing furnace shell 110 and the inner shell 112, making it difficult for the gas in the processing furnace chamber 111 to leak out from one side of the furnace door 119.
[0093] Implementation Method 4
[0094] The inventor of the present application discovered that Figure 3As shown, when the thermal insulation performance of the regeneration processing furnace 1 is not good enough, the heat in the processing furnace chamber 111 will diffuse outward from the processing furnace shell 110. This part of the heat cannot act on the effective cracking of the fiber reinforced composite material waste 122, resulting in unnecessary heat loss.
[0095] To this end, an embodiment of the present application proposes a regeneration processing furnace 1, which further includes a first thermal insulation layer 120, and the first thermal insulation layer 120 is arranged between the inner shell 112 and the processing furnace shell 110.
[0096] In an embodiment of the present application, the first thermal insulation layer 120 is disposed on the inner wall of the processing furnace shell 110, and the fiber reinforced composite material waste 122 will be thermally decomposed in the area formed by the first thermal insulation layer 120. At the same time, the heat generated in the area formed by the first thermal insulation layer 120 cannot be easily transmitted to the external environment through the first thermal insulation layer 120, so that the fiber reinforced composite material waste 122 can be effectively cracked in a stable temperature environment, so that the resin matrix in the fiber reinforced composite material waste 122 can be effectively gasified to generate cracking gas, which is beneficial to the extraction of carbon fiber.
[0097] Optionally, the air intake assembly 114 and the second exhaust assembly 116 are disposed on a side of the processing furnace shell 110 away from the furnace door 119 , and the first exhaust assembly 115 is disposed on the top of the processing furnace shell 110 .
[0098] In an embodiment of the present application, the air intake assembly 114 and the second exhaust assembly 116 are arranged on the side of the processing furnace shell 110 away from the furnace door 119, that is, the air intake assembly 114 and the second exhaust assembly 116 can be arranged on the back side of the processing furnace shell 110, and the first exhaust assembly 115 is arranged on the top of the processing furnace shell 110, so that the air intake assembly 114, the second exhaust assembly 116 and the first exhaust assembly 115 can be reasonably distributed on the processing furnace shell 110 to avoid causing too obvious impact on the structural strength.
[0099] Optionally, the heating device 117 includes a plurality of heating parts, and the plurality of heating parts are evenly arranged around the processing furnace chamber 111 .
[0100] In an embodiment of the present application, the heating device 117 includes a plurality of heating parts, and optionally, the heating parts include electric heating tubes. The plurality of heating parts are evenly arranged around the processing furnace chamber 111, so that an effective heating area can be vertically distributed from top to bottom on both sides of the outer side of the inner shell 112 forming the processing furnace chamber 111, so as to provide more uniform heat inside the processing furnace chamber 111.
[0101] It is worth noting that the heat source for heating the fiber reinforced composite waste 122 inside the processing furnace chamber 111 may include superheated steam, a heating device 117, and clean high-temperature hot air entering the heating chamber 113 from the supplementary heat air inlet. When the fiber reinforced composite waste 122 in the processing furnace chamber 111 is in the initial stage of the reaction, when the cracking gas has not yet been generated, or when the flow rate of the cracking gas is relatively small, the heat source is mainly provided by the heating device 117. When the cracking gas is generated and converted into clean high-temperature hot gas through the thermal energy conversion furnace, the high-temperature hot gas is transported to the heating chamber 113, and the high-temperature hot gas serves as the main heat source. At this time, the heating device 117 can be used as an auxiliary heat source. The heating device 117 and the high-temperature hot gas are used simultaneously to provide sufficient heat for the thermal cracking of the fiber reinforced composite waste 122.
[0102] Implementation Method 5
[0103] like Figure 4 As shown, an embodiment of the present application provides a superheated steam generator 2, including an inner tank 21, an outer tank 22, a heating element 24 and a temperature control element 25, wherein the inner tank 21 has an installation cavity, the outer tank 22 is arranged on a side of the inner tank 21 away from the installation cavity, a steam channel is provided between the outer tank 22 and the inner tank 21, at least a portion of the heating element 24 is located in the installation cavity, and the temperature control element 25 is arranged on the heating element 24.
[0104] The superheated steam generator 2 of the present application includes an inner liner 21, an outer liner 22, a heating element 24 and a temperature control element 25. The inner liner 21 has a mounting cavity, and the outer liner 22 is arranged on the side of the inner liner 21 away from the mounting cavity, wherein the side pointing to the center of the mounting cavity is the inner side, and the side away from the center of the mounting cavity is the outer side. That is, the outer liner 22 is arranged on the outer side of the inner liner 21, and there is a steam channel between the inner liner 21 and the outer liner 22, and the steam channel is used for steam circulation. It can be imagined that the steam channel has an inlet 235 and a steam outlet 236, so that steam can circulate in the steam channel.
[0105] Among them, at least a part of the heating element 24 is arranged in the installation cavity, for example, the heating element 24 is completely located in the installation cavity, and can quickly and efficiently exchange heat with the steam in the steam channel. Alternatively, a part of the heating element 24 is located in the installation cavity, and the other part of the heating element 24 is exposed relative to the installation cavity. The exposed part of the heating element 24 can facilitate the electrical connection of the heating element 24, and the safety performance is higher. It is worth noting that the heating element 24 is used to provide a heat source, and the heat generated by the heating element 24 can heat the water and / or steam in the steam channel, so as to obtain high-temperature steam that meets the needs.
[0106] Among them, water and / or saturated steam can enter the steam channel through the inlet 235. After being heated by the heat generated by the heating element 24 in the steam channel, the water and / or saturated steam becomes superheated steam, and then is discharged from the steam outlet 236. It is worth noting that the saturated steam can come from a steam boiler. The temperature of saturated steam is 100°C to 200°C, the oxygen content of superheated steam is less than 0.3%, and the temperature of superheated steam is in the range of 400°C to 700°C under normal pressure.
[0107] For example, when water enters the steam channel through the inlet 235, heat is generated through the heating element 24 to heat the water in the steam channel, thereby generating saturated steam. The heating element 24 continues to heat the steam channel, and the saturated steam will be converted into superheated steam. The superheated steam has an oxygen content of less than 0.3% and a temperature in the range of 400°C to 700°C under normal pressure, which meets user needs.
[0108] The temperature control unit 25 is provided on the heating element 24. The temperature control unit 25 is used to detect the working parameters of the heating element 24 and can adjust the working parameters of the heating element 24, so as to control the steam temperature and steam pressure in the steam channel. The working parameters of the heating element 24 include but are not limited to heating power and heating time.
[0109] The superheated steam generator 2 provided in the present application abandons the solution of preparing superheated steam by a traditional pressure boiler, and has the characteristics of easy use, simple structure and high safety performance, which effectively improves the application scope of superheated steam. At the same time, by setting a temperature control unit 25 on the heating element 24, the control of the working parameters of the heating element 24 is achieved, so that the parameters of the superheated steam generated by the superheated steam generator 2 are controllable and can meet the needs of different scenarios.
[0110] Optionally, the inner liner 21 is made of a material with high thermal conductivity. During the heat transfer process, the heat generated by the heating element 24 can be quickly transferred to the steam channel through the inner liner 21. On the one hand, the thermal efficiency is improved. On the other hand, since the heat on the inner liner 21 is quickly taken away by the steam, the temperature of the inner liner 21 is reduced, and the adverse effect of the heat on the structure of the inner liner 21 itself can be minimized, thereby extending the service life of the inner liner 21. Optionally, the inner liner 21 is a heat-resistant stainless steel tube.
[0111] Optionally, the outer container 22 is made of a material with low thermal conductivity, which reduces the heat dissipation caused by heat transfer between the steam and the outer container 22, and improves the thermal efficiency. Among them, the temperature control unit 25 collects the temperature of the steam channel, generates a conduction or disconnection action according to the temperature of the steam channel, adjusts the output power of the heating element 24, and realizes the control of the steam temperature. Optionally, the outer container 22 is a heat-resistant stainless steel tube.
[0112] Optionally, the heating element 24 includes a first heating element 241 and a second heating element 242, and the temperature control unit 25 is disposed on the first heating element 241 and / or the second heating element 242. The steam channel includes a first steam channel 231 and a second steam channel 232, the first steam channel 231 includes an inlet 235, the first heating element 241 is used to heat the first steam channel 231, the second steam channel 232 is connected to the first steam channel 231, the second steam channel 232 includes a steam outlet 236, and the second heating element 242 is used to heat the second steam channel 232.
[0113] In the embodiment of the present application, the heating element 24 includes a first heating element 241 and a second heating element 242, the steam channel includes a first steam channel 231 and a second steam channel 232, the first heating element 241 is used to heat water and / or steam in the first steam channel 231, and the second heating element 242 is used to heat water and / or steam in the second steam channel 232. The combined use of the first heating element 241 and the second heating element 242 can effectively improve the heating efficiency of the heating element 24, so that the possibility of obtaining a large amount of superheated steam per unit time is greatly improved.
[0114] The temperature control unit 25 may be disposed on the first heating element 241, or the temperature control unit 25 may be disposed on the second heating element 242, or the temperature control unit 25 may be disposed on both the first heating element 241 and the second heating element 242. The temperature control unit 25 may adjust the working parameters of the first heating element 241 and the second heating element 242, thereby achieving temperature adjustment of the first steam channel 231 and the second steam channel 232.
[0115] Regarding the steam channel, it includes a first steam channel 231 and a second steam channel 232 that are connected. The first steam channel 231 has an inlet 235, and the second steam channel 232 has a steam outlet 236. That is to say, water and / or saturated steam can enter the first steam channel 231 through the inlet 235, and then flow from the first steam channel 231 to the second steam channel 232. At the same time, the heat generated by the heating element 24 will heat the water and / or steam inside the first steam channel 231 and the second steam channel 232, and finally the superheated steam will be discharged from the steam outlet 236.
[0116] Optionally, at least a portion of the second steam channel 232 extends in a zigzag manner relative to the first steam channel 231 .
[0117] In an embodiment of the present application, at least a portion of the second steam channel 232 extends in a tortuous manner relative to the first steam channel 231, that is, the steam channel as a whole is a tortuous channel. When water and / or steam flows in the steam channel, the tortuous steam channel can extend the flow path and the flow market, thereby making the heat exchange more sufficient and thorough, so that the superheated steam finally discharged through the steam outlet 236 can meet user requirements.
[0118] Optionally, the first steam channel 231 extends along a first direction, the second steam channel 232 includes a connecting channel 233 and an exhaust channel 234, the exhaust channel 234 is connected to the first steam channel 231 through the connecting channel 233, the exhaust channel 234 extends along the first direction, and the connecting channel 233 extends along a second direction different from the first direction.
[0119] In the embodiment of the present application, the first steam channel 231 extends along the first direction, the second steam channel 232 includes a connecting channel 233 and an exhaust channel 234, the exhaust channel 234 is connected to the first steam channel 231 through the connecting channel 233, and the exhaust channel 234 has a steam outlet 236. In other words, the connecting channel 233 is located between the first steam channel 231 and the exhaust channel 234. Among them, the exhaust channel 234 and the first steam channel 231 both extend along the first direction, and the connecting channel 233 extends along the second direction, which is different from the first direction, so that the second steam channel 232 is divided into two sections with different extension directions, thereby meeting the requirement of the steam channel to extend in a tortuous manner.
[0120] For example, the first direction may be a vertical direction, and the second direction may be a horizontal direction. Then, for the steam channel, its longitudinal section along the vertical plane is roughly in a "U" shape.
[0121] Optionally, a guide structure may be provided at the connection point between the first steam channel 231 and the connecting channel 233 to reduce resistance of steam during circulation.
[0122] Optionally, a guide structure may be provided at the connection point between the connecting channel 233 and the exhaust channel 234 to reduce the resistance of the steam during the circulation process.
[0123] Implementation Method 6
[0124] The inventors of this application discovered that when the thermal insulation performance of the outside of the steam channel is not good enough, part of the heat will diffuse from the outside of the steam channel to the external environment. This part of the heat cannot act on the water and / or steam inside the steam channel, resulting in unnecessary heat loss.
[0125] For this reason, Figure 4As shown, one embodiment of the present application proposes a superheated steam generator 2, including a generator shell 26 and a second insulation layer 27, the generator shell 26 has an assembly cavity, at least a portion of the inner liner 21 and at least a portion of the outer liner 22 are located in the assembly cavity; the second insulation layer 27 is arranged in the assembly cavity and is located between the outer liner 22 and the generator shell 26.
[0126] In an embodiment of the present application, the superheated steam generator 2 further includes a generator shell 26 and a second insulation layer 27. The generator shell 26 has an assembly cavity. The generator shell 26 can constitute the outer contour of the superheated steam generator 2 and protect its internal structural parts.
[0127] Among them, at least a part of the inner liner 21 is located in the assembly cavity, at least a part of the outer liner 22 is located in the assembly cavity, and the steam channel between the inner liner 21 and the outer liner 22 is located inside the generator housing 26, that is, located in the assembly cavity. The generator housing 26 itself can also play a certain role in heat insulation, blocking heat from being transferred to the outside.
[0128] Furthermore, a second thermal insulation layer 27 is provided between the generator housing 26 and the outer shell 22. The second thermal insulation layer 27 is located in the assembly cavity. The second thermal insulation layer 27 is used to block the heat inside the steam channel from being transferred to the outside of the generator housing 26, so that the heat can be gathered inside the steam channel, thereby increasing the heat of water and / or steam inside the steam channel as much as possible and avoiding unnecessary heat loss.
[0129] Optionally, an assembly opening is provided on the generator housing 26 , a portion of the heating element 24 passes through the assembly opening and is exposed relative to the generator housing 26 , and the temperature control element 25 is exposed relative to the generator housing 26 .
[0130] In an embodiment of the present application, an assembly opening is provided on the generator housing 26, so that a portion of the heating element 24 can pass through the assembly opening, and the heating element 24 is exposed relative to the assembly cavity. The exposed portion of the heating element 24 can facilitate the setting of the temperature control unit 25, thereby improving the safe use performance of the superheated steam generator 2 and reducing the interference of steam on electrical connection components.
[0131] Optionally, the superheated steam generator 2 further includes a plurality of reinforcing ribs 28 , which are arranged on the generator shell 26 at intervals.
[0132] In an embodiment of the present application, the superheated steam generator 2 also includes a plurality of reinforcing ribs 28, which are arranged at intervals on the generator housing 26. Since the generator housing 26 has components that bring heat, such as a heating element 24 and a steam channel, inside, the generator housing 26 itself has a large temperature difference between its inside and outside, that is, the working environment of the generator housing 26 poses a relatively large test on its own structural strength and structural stability. By arranging a plurality of reinforcing ribs 28 on the generator housing 26, the structural stability of the generator housing 26 can be effectively guaranteed and the possibility of deformation of the generator housing 26 can be reduced.
[0133] Implementation Method 7
[0134] The inventors of the present application have discovered that after the superheated steam generator 2 is used, there is often residual water in the steam channel. If the water is not discharged in time, the service life of the superheated steam generator 2 may be affected.
[0135] For this reason, Figure 4 As shown, one embodiment of the present application provides a superheated steam generator 2, which includes a drainage component 29, and the drainage component 29 can be communicated with the steam channel.
[0136] In the embodiment of the present application, the superheated steam generator 2 includes a drainage component 29, which is connected to the steam channel. During normal use of the superheated steam generator 2, the drainage component 29 is closed to ensure that the steam channel can discharge superheated steam. When the superheated steam generator 2 is finished using, the drainage component 29 can be opened to allow the residual water inside the steam channel to be discharged from the drainage component 29, thereby extending the service life of the superheated steam generator 2.
[0137] Optionally, a drain assembly 29 is located at the bottom of the steam channel.
[0138] In the embodiment of the present application, the drainage component 29 is arranged at the bottom of the steam channel, and the residual water can be discharged to the outside through the drainage component 29 under the action of gravity, without the need for additional structure to lead out the residual water.
[0139] Optionally, the drain assembly 29 includes a drain valve.
[0140] Implementation Method 8
[0141] like Figure 5As shown, an embodiment of the present application provides a heat conversion combustion furnace 3, which is used for waste regeneration and processing equipment. The heat conversion combustion furnace 3 includes a conversion furnace shell 310, a first burner 312, a second burner 313 and a third exhaust assembly 314. The conversion furnace shell 310 has a conversion furnace chamber 311. The first burner 312 is arranged on the conversion furnace shell 310 and is connected to the conversion furnace chamber 311. The first burner 312 is used to ignite cracking gas. The second burner 313 is arranged on the conversion furnace shell 310 and is connected to the conversion furnace chamber 311. The second burner 313 is used to ignite fuel gas. The third exhaust assembly 314 is arranged on the conversion furnace shell 310 and is connected to the conversion furnace chamber 311.
[0142] The heat conversion combustion furnace 3 of the present application is used for waste regeneration and processing equipment, wherein the heat conversion combustion furnace 3 includes a conversion furnace shell 310, a first burner 312, a second burner 313 and a third exhaust assembly 314, wherein the conversion furnace shell 310 has a conversion furnace chamber 311, and the conversion furnace chamber 311 provides a combustion space. The first burner 312 is arranged on the conversion furnace shell 310, and the first burner 312 is connected to the conversion furnace chamber 311, and the first burner 312 is used to ignite the cracking gas, that is, the cracking gas will be ignited at the first burner 312. The second burner 313 is arranged on the conversion furnace shell 310, and the second burner 313 is connected to the conversion furnace chamber 311, and the second burner 313 is used to ignite the fuel gas, that is, the fuel gas will be ignited at the second burner 313. With the cooperation of the first burner 312 and the second burner 313, the cracking gas can be fully and effectively burned in the conversion furnace chamber 311, thereby obtaining a clean heat source, which can be discharged through the third exhaust assembly 314. The clean heat source will not cause environmental pollution and can also reduce costs. As for the specific destination of the clean heat source, it can be directly discharged to the external environment, or it can be directly transported to other components of the waste regeneration and treatment equipment, thereby reducing the cost of waste recycling and adapting to the sustainable, green and low-carbon development trend of the industry.
[0143] It is worth noting that the waste recycling and treatment equipment is used for carbon fiber reinforced composite materials, and the cracking gas is a combustible organic small molecule gas. The fuel gas includes natural gas or coal gas. The clean heat source includes non-toxic high-temperature hot air.
[0144] The thermal energy conversion combustion furnace 3 further includes a base 320 , which is disposed at the bottom of the conversion furnace shell 310 to support the conversion furnace shell 310 .
[0145] During the operation of the heat conversion combustion furnace 3, if there is no cracking gas in the early stage, the second burner 313 can be used to introduce fuel gas into the conversion furnace chamber 311 and ignite it, so that when the cracking gas enters the conversion furnace chamber 311, the temperature in the conversion furnace chamber 311 can reach a preset temperature, which is conducive to the full combustion reaction of the cracking gas. As a large amount of cracking gas is produced, the cracking gas at the first burner 312 is sufficient to meet the combustion needs. At this time, the gas supply at the second burner 313 can be controlled to stop, or a small amount can be supplied to maintain a long flame. In other words, in different working stages of the heat conversion combustion furnace 3, the working parameters of the first burner 312 and the second burner 313 can be controlled to meet the combustion needs of different cracking gas flow rates at different stages, making the versatility of the heat conversion combustion furnace 3 more excellent and meeting the needs of different usage scenarios.
[0146] Optionally, the first burner 312 and the third exhaust assembly 314 are disposed on two opposite side walls of the converter shell 310 .
[0147] In an embodiment of the present application, the conversion furnace shell 310 has two opposite side walls, for example, the front side wall of the conversion furnace shell 310, the rear side wall of the conversion furnace shell 310, or the left side wall of the conversion furnace shell 310, the right side wall of the conversion furnace shell 310, and the first burner 312 and the third exhaust assembly 314 are respectively arranged on the opposite side walls. When the cracking gas is ignited at the first burner 312, the cracking gas can be burned as fully as possible in the conversion furnace chamber 311, and the possibility of incompletely burned cracking gas being discharged from the third exhaust assembly 314 is eliminated, so that the gas reaching the third exhaust assembly 314 is all clean high-temperature gas, rather than toxic gas.
[0148] Optionally, the second burner 313 is disposed on the top wall of the converter shell 310 .
[0149] In an embodiment of the present application, the second burner 313 is arranged on the top wall of the conversion furnace shell 310, and the first burner 312 and the third exhaust assembly 314 are arranged on two opposite side walls of the conversion furnace shell 310 along the front and rear directions, that is, the first burner 312, the second burner 313 and the third exhaust assembly 314 are respectively arranged on different wall surfaces of the conversion furnace shell 310, so that the structural layout of the thermal energy conversion combustion furnace 3 is more reasonable, avoiding the problems such as reduced structural strength that may exist due to the concentrated arrangement of the first burner 312, the second burner 313 and the third exhaust assembly 314.
[0150] Optionally, the third exhaust assembly 314 includes at least two exhaust ports and a switching valve, at least two exhaust ports are arranged on the conversion furnace shell 310, and the switching valve is arranged at the at least two exhaust ports. At least two exhaust ports can be connected to the conversion furnace chamber 311 through the switching valve.
[0151] In the embodiment of the present application, the third exhaust component 314 includes at least two exhaust ports and a switching valve. For the clean heat source generated after the cracking gas is fully burned, that is, the high-temperature hot gas, there are multiple options for the destination of the high-temperature hot gas to meet the distribution and utilization of the high-temperature hot gas. For example, it can be transported to other components of the waste recycling and treatment equipment. For example, when the waste recycling equipment also includes a superheated steam generator 2 and a regeneration treatment furnace 1, the high-temperature hot gas can be selectively transported to the superheated steam generator 2 and / or the regeneration treatment furnace 1, and can be used as a heat source or supplementary heat source for the superheated steam generator 2 and the regeneration treatment furnace 1.
[0152] For example, the switching valve may include an electrically-actuated butterfly valve.
[0153] The third exhaust assembly 314 also includes a pressure sensor to further meet the distribution and utilization of high-temperature hot air.
[0154] When the number of exhaust ports is two, one exhaust port is connected to the superheated steam generator 2 through a pipeline, and the other exhaust port can be connected to the regeneration treatment furnace 1 through a pipeline, and the conversion furnace chamber 311 can be connected to at least one of the two exhaust ports through a switching valve, so that the connection mode can be adjusted by the switching valve in different working stages. Specifically, the conversion furnace chamber 311 can be connected to only one of the superheated steam generator 2 and the regeneration treatment furnace 1, or the conversion furnace chamber 311 can be connected to both the superheated steam generator 2 and the regeneration treatment furnace 1, which can be set according to actual needs, and the setting of the switching valve provides multiple options for actual needs.
[0155] Implementation Method 9
[0156] The inventors of the present application have discovered that when the cracking gas burns in the conversion furnace chamber 311, the pressure inside the conversion furnace chamber 311 will be higher than the pressure of the external environment. If the internal pressure of the thermal energy conversion combustion furnace 3 cannot be accurately regulated, it will cause safety problems.
[0157] For this reason, Figure 5 As shown, one embodiment of the present application proposes a thermal energy conversion combustion furnace 3, which also includes a control component 118. The control component 118 is arranged on the conversion furnace shell 310, and the control component 118 is used to regulate the internal temperature of the conversion furnace chamber 311 and / or the internal pressure of the conversion furnace chamber 311.
[0158] In the embodiment of the present application, the heat conversion combustion furnace 3 also includes a control component 118, which is arranged on the conversion furnace shell 310. The control component 118 can adjust the internal temperature of the conversion furnace chamber 311 so that the temperature in the conversion furnace chamber 311 reaches the temperature required for the combustion of the cracking gas. When the cracking gas is generated by the combustion of the carbon fiber reinforced composite material, that is, the cracking gas is a combustible organic small molecule gas generated by the gasification of the matrix resin, then, at this time, it is necessary to ensure that the temperature in the heat conversion combustion furnace 3 reaches about 900°C. At this temperature, the cracking gas can be effectively decomposed to form non-toxic clean high-temperature hot gas, such as CO2 and H2O, to achieve sustainable development of the environment. If there is no control component 118 to accurately control the temperature in the conversion furnace chamber 311, it is impossible to ensure the effective decomposition of the cracking gas, and it is impossible to ensure that the gas discharged from the third exhaust component 314 meets the environmental protection standards, which is easy to cause pollution problems.
[0159] The control component 118 can also regulate the internal pressure of the conversion furnace chamber 311 so that the internal pressure of the conversion furnace chamber 311 is lower than the maximum bearing pressure, thereby ensuring the safe use of the thermal energy conversion combustion furnace 3.
[0160] Optionally, the thermal energy conversion combustion furnace 3 further includes a safety cap 316 , which is disposed on the conversion furnace shell 310 .
[0161] In an embodiment of the present application, when the control component 118 fails to control the internal pressure of the conversion furnace chamber 311, resulting in the internal pressure of the conversion furnace chamber 311 being too high, the safety cap 316 can be used to automatically release the pressure by physical means, thereby further ensuring the safety of the operation of the thermal energy conversion combustion furnace 3.
[0162] In the embodiment of the present application, the temperature in the conversion furnace chamber 311 can be maintained at about 900° C. by the control component 118 , so that the pressure inside the conversion furnace chamber 311 can be stabilized.
[0163] Implementation Method 10
[0164] The inventors of the present application have found that after the thermal energy conversion combustion furnace 3 is used, water often accumulates in the pipeline for conveying cracked gas. If the accumulated water cannot be removed, it is easy to affect the conveying efficiency of the cracked gas and the processing efficiency of the waste regeneration and processing equipment.
[0165] For this reason, Figure 5 As shown, an embodiment of the present application proposes a thermal energy conversion combustion furnace 3, which also includes a drip hole 317, and the drip hole 317 is arranged on the conversion furnace shell 310.
[0166] In the embodiment of the present application, the cracking gas is transported to the first burner 312 through a pipeline, and water is easily accumulated in the pipeline. By setting a drip hole 317 on the conversion furnace shell 310, the accumulated water in the pipeline can be discharged into the conversion furnace chamber 311 through the drip hole 317, and cleaned at a temperature of 900°C, thereby solving the problem of water accumulation in the pipeline, ensuring the integrity of the waste regeneration and treatment equipment, and eliminating the problem of cracking gas leakage, thereby ensuring that the cracking gas transportation efficiency and the treatment efficiency of the waste regeneration and treatment equipment are not affected.
[0167] Implementation Method Eleven
[0168] The inventors of the present application have discovered that when the thermal insulation performance of the heat conversion combustion furnace 3 is not good enough, the heat in the conversion furnace chamber 311 will diffuse outward from the conversion furnace shell 310. This part of the heat cannot act on the effective decomposition of the cracking gas, resulting in unnecessary heat loss.
[0169] For this reason, Figure 5 As shown, one embodiment of the present application proposes a thermal energy conversion combustion furnace 3, which also includes a third thermal insulation layer 318, and the third thermal insulation layer 318 is arranged on the inner wall of the conversion furnace shell 310.
[0170] In an embodiment of the present application, the third insulation layer 318 is arranged on the inner wall of the conversion furnace shell 310, and the cracking gas will be fully burned in the combustion zone formed by the third insulation layer 318. The generated heat cannot be easily transmitted to the external environment through the third insulation layer 318, so that the cracking gas can be effectively decomposed in a stable temperature environment, thereby forming clean high-temperature hot gas, avoiding pollution to the environment. At the same time, it can also provide a clean heat source with a higher temperature as much as possible, provide sufficient heat source support for other components of the waste regeneration and processing equipment, and improve the recycling rate.
[0171] Implementation Method Twelve
[0172] The inventors of the present application have discovered that when the conversion furnace chamber 311 of the thermal energy conversion combustion furnace 3 does not have visualization performance, it is difficult to detect problems in time during the combustion process, which often leads to serious consequences and is inconvenient for maintenance and operation.
[0173] For this reason, Figure 5 As shown, an embodiment of the present application proposes a thermal energy conversion combustion furnace 3, a conversion furnace shell 310 is provided with a perspective window 319, and the perspective window 319 is detachably arranged on the conversion furnace shell 310.
[0174] In an embodiment of the present application, a perspective window 319 is provided on the conversion furnace shell 310, and the perspective window 319 can realize the visualization of the interior of the conversion furnace cavity 311. The user can intuitively observe the combustion status inside the conversion furnace cavity 311 through the perspective window 319. If there is an abnormality in the combustion process, it can be dealt with in time, for example, shutting down immediately to avoid serious consequences.
[0175] Furthermore, the perspective window 319 is detachably provided on the converter shell 310. When the user needs to repair the components in the converter cavity 311, the repair can be performed through the perspective window 319, thereby simplifying the difficulty of repair.
[0176] Implementation Method Thirteen
[0177] like Figure 6 As shown, one embodiment of the present application proposes a hot air delivery device 4, such as Figure 1 As shown, it includes a shell 41, a first air inlet, a first air outlet, a second air inlet and a second air outlet, wherein the shell 41 includes a heat exchange chamber 411, the first air inlet and the first air outlet are respectively arranged on the shell 41 and communicated with the heat exchange chamber 411, the first air inlet is used to input air to be heated, the second air inlet and the second air outlet are respectively arranged on the shell 41 and communicated with the heat exchange chamber 411, and the second air inlet is used to input hot air.
[0178] The hot air conveying device 4 of the present application comprises a shell 41, a first air inlet, a first air outlet, a second air inlet and a second air outlet, wherein the shell 41 comprises a heat exchange chamber 411, and the heat exchange chamber 411 is used for heat exchange of air. The first air inlet and the first air outlet constitute one of the flow paths of air, and the air to be heated enters the heat exchange chamber 411 through the first air inlet, and heat exchange is performed inside the heat exchange chamber 411. After the temperature rises, the air is discharged to the outside of the shell 41 through the first air outlet. The second air inlet and the second air outlet constitute the second flow path of air, and the hot air enters the heat exchange chamber 411 through the second air inlet. The hot air serves as a heat source, and the hot air entering the heat exchange chamber 411 can exchange heat with the air to be heated. The temperature of the air to be heated rises, and the temperature of the hot air decreases. After the temperature of the air to be heated reaches the target temperature, it is discharged from the first air outlet, and the hot air after heat exchange is discharged to the outside of the shell 41 through the second air outlet.
[0179] In the present application, two air flow paths are formed by the first air inlet, the first air outlet, the second air inlet and the second air outlet. For each air flow path, that is, for the air to be heated and the hot air, there are corresponding air inlets and air outlets, which can make the air in the heat exchange chamber 411 flow more smoothly. The air in the heat exchange chamber 411 can flow out from the first air outlet or the second air outlet nearby, reducing the noise problem caused by the vortex of air inside the shell 41, and reducing the loss of flow rate / pressure inside the heat exchange chamber 411 as much as possible, which can ensure the circulation efficiency of the air and the production rhythm.
[0180] It is worth noting that in order to enable the air to flow along a predetermined air flow path, a driving member is provided on the air flow path, and the driving member is used to drive the air to enter the heat exchange cavity 411 from the first air inlet and then be discharged from the first air outlet.
[0181] It is conceivable that the driving member is also used to drive air to enter the heat exchange chamber 411 from the second air inlet and then be discharged from the second air outlet.
[0182] For example, the driving member may be a driving fan.
[0183] Alternatively, if Figure 1 As shown, the first air inlet and the first air outlet are respectively arranged on two adjacent walls of the shell 41.
[0184] In an embodiment of the present application, the shell 41 has two adjacent walls, the heat exchange chamber 411 is located between the two opposite walls, and the first air inlet and the second air inlet are respectively located on the two adjacent walls. Then, for one of the air flow paths, the air to be heated will enter the heat exchange chamber 411 through the first air inlet, and the air after heat exchange will be discharged from the first air outlet. The movement path of the air to be heated in the heat exchange chamber 411 is close to a corner of the heat exchange chamber 411, so as to avoid mutual obstruction between the air to be heated and the hot air, which can further reduce the flow rate / pressure loss.
[0185] Optionally, when the shell 41 includes six walls, for example, a vertical wall, a horizontal wall, and a front-rear wall, the first air inlet and the first air outlet can be arranged on any adjacent wall among the six walls.
[0186] Alternatively, if Figure 1 As shown, the second air inlet and the second air outlet are respectively arranged on two adjacent wall surfaces of the shell 41.
[0187] In an embodiment of the present application, for the second air flow path, the hot air will enter the heat exchange chamber 411 through the second air inlet, and the air after heat exchange will be discharged from the second air outlet. The movement path of the hot air in the heat exchange chamber 411 is close to a corner of the heat exchange chamber 411, so as to avoid mutual obstruction between the air to be heated and the hot air, which can further reduce the flow rate / pressure loss.
[0188] It is conceivable that the second air inlet and the second air outlet may be arranged on any adjacent wall among the six wall surfaces.
[0189] Alternatively, if Figure 1 As shown, the housing 41 includes a top wall, a bottom wall and a plurality of side walls, the top wall and the bottom wall are arranged in the up-down direction, the second air inlet is arranged on the bottom wall, and the first air outlet is arranged on the top wall. The plurality of side walls are arranged between the top wall and the bottom wall, the first air inlet is arranged on one side wall, and the second air outlet is arranged on the other side wall.
[0190] In the embodiment of the present application, the housing 41 includes a top wall, a bottom wall and a plurality of side walls, the top wall and the bottom wall are arranged in the up-down direction, and the second air inlet is arranged on the bottom wall, that is, the hot air passes through the heat exchange cavity 411 from bottom to top, which is adapted to the upward flow trend of the hot air, and can make the flow of the hot air smoother and reduce the resistance of the flow process. The first air outlet is arranged on the top wall, because the temperature of the air to be heated rises after being heated in the heat exchange cavity 411, and it is discharged through the first air outlet on the top wall, which is also adapted to the flow trend of the high-temperature airflow.
[0191] In other words, for the second air flow path, the hot air flows into the heat exchange cavity 411 from bottom to top, and then flows out through the second air outlet on the side wall.
[0192] Among them, multiple side walls are arranged between the top wall and the bottom wall, and the multiple side walls can be understood as wall surfaces in the peripheral direction, such as the front side wall, the rear side wall, the left side wall, and the right side wall. The first air inlet is arranged on one of the multiple side walls, and the second air outlet is arranged on another side wall of the multiple side walls. For example, the first air inlet is arranged on one of the front side wall and the rear side wall, and the second air outlet is arranged on the other of the front side wall and the rear side wall. Alternatively, the first air inlet is arranged on one of the left side wall and the right side wall, and the second air outlet is arranged on the other of the left side wall and the right side wall.
[0193] For example, the first air inlet is arranged on the left wall, and the second air outlet is arranged on the right wall. Then, for one of the air flow paths, the air to be heated enters the heat exchange chamber 411 from left to right through the first air inlet, and then after heat exchange, is discharged upward through the first air outlet.
[0194] As for the second air flow path, the hot air enters the heat exchange chamber 411 from bottom to top through the second air inlet, exchanges heat with the air to be heated in the heat exchange chamber 411, and then is discharged to the right outside the shell 41 through the second air outlet.
[0195] Wherein, heat exchange can be achieved between the air flow paths, and the flow paths of the two will not be combined with each other to affect the efficiency.
[0196] Optionally, the first air inlet and the second air outlet are coaxially arranged.
[0197] In an embodiment of the present application, the first air inlet and the second air outlet respectively have a central axis, and the direction of the central axis is the flow direction of the air through the first air inlet or the second air outlet. When the central axes of the first air inlet and the second air outlet are coaxially arranged, then for the air flow path, the air to be heated and the hot air can meet in the heat exchange chamber 411 to achieve heat exchange, thereby increasing the temperature of the air to be heated. At the same time, it can also reduce the flow rate / pressure loss during the flow process.
[0198] Optionally, the second air inlet and the first air outlet are coaxially arranged.
[0199] In an embodiment of the present application, the second air inlet and the first air outlet respectively have a central axis, and the direction of the central axis is the flow direction of the air through the second air inlet or the first air outlet. When the central axes of the second air inlet and the first air outlet are coaxially arranged, then for the air flow path, the air to be heated and the hot air can meet in the heat exchange chamber 411 to achieve heat exchange, thereby increasing the temperature of the air to be heated. At the same time, it can also reduce the flow rate / pressure loss during the flow process.
[0200] Optionally, a flow cross-sectional area of any one of the first air inlet and the first air outlet is smaller than a flow cross-sectional area of any one of the second air inlet and the second air outlet.
[0201] In the embodiments of the present application, the flow cross-sectional area refers to the area of the first air inlet on the cross section perpendicular to the central axis, that is, the cross section of the first air inlet. When the first air inlet is a circular hole, the flow cross-sectional area of the first air inlet is a circular area. For the first air outlet, the second air inlet and the second air outlet, the definition of the flow cross-sectional area is also applicable.
[0202] As for the air flow path, the air enters the heat exchange chamber 411 through the air inlet (the first air inlet, the second air inlet), exchanges heat inside the heat exchange chamber 411, and then is discharged from the air outlet (the first air outlet, the second air outlet).
[0203] Among them, according to the air flow requirements, the flow rates of the first air inlet and the second air inlet are smaller than those of the second air inlet and the second air outlet. As the second air flow path of the heat source, in order to provide sufficient heat, the flow rate of the hot air needs to be relatively large so as to meet the heat exchange requirements.
[0204] Alternatively, if Figure 1 As shown, the hot air delivery device 4 further includes a first air inlet pipe 421 , which is disposed on the shell 41 and communicates with the heat exchange chamber 411 through a first air inlet.
[0205] In an embodiment of the present application, the hot air conveying device 4 also includes a first air inlet pipe 421, which is arranged on the shell 41 and connected to the heat exchange chamber 411 through a first air inlet port. The first air inlet pipe 421 can be conveniently assembled and connected with the structure to be installed, and can adapt to the installation requirements of different structures to be installed.
[0206] Optionally, the first air inlet pipe 421 is detachably disposed on the housing 41 , and the first air inlet pipe 421 can be disassembled and assembled as required.
[0207] Alternatively, if Figure 1 As shown, the hot air delivery device 4 further includes a first air outlet pipe 422 , which is disposed on the shell 41 and communicates with the heat exchange cavity 411 through a first air outlet.
[0208] In an embodiment of the present application, the hot air conveying device 4 also includes a first air outlet pipe 422, which is arranged on the shell 41 and connected to the heat exchange chamber 411 through the first air outlet. The first air outlet pipe 422 can be conveniently assembled and connected with the structure to be installed, and can adapt to the installation requirements of different structures to be installed.
[0209] Optionally, the first air outlet pipe 422 is detachably disposed on the housing 41 , and the first air outlet pipe 422 can be disassembled and assembled as required.
[0210] For one of the air flow paths, the air to be heated enters the heat exchange chamber 411 through the first air inlet pipe 421 and the first air inlet port, completes the heat exchange process in the heat exchange chamber 411, and is discharged to the outside of the heat exchange chamber 411 through the first air outlet and the first air outlet pipe 422.
[0211] Alternatively, if Figure 1 As shown, the hot air delivery device 4 further includes a second air inlet pipe 423 , which is disposed on the shell 41 and communicates with the heat exchange chamber 411 through a second air inlet port.
[0212] In an embodiment of the present application, the hot air conveying device 4 also includes a second air inlet pipe 423, which is arranged on the shell 41 and connected to the heat exchange chamber 411 through a second air inlet port. The second air inlet pipe 423 can be conveniently assembled and connected with the structure to be installed, and can adapt to the installation requirements of different structures to be installed.
[0213] Optionally, the second air inlet pipe 423 is detachably disposed on the housing 41 , and the second air inlet pipe 423 can be disassembled and assembled as required.
[0214] Alternatively, if Figure 1 As shown, the hot air delivery device 4 further includes a second air outlet pipe 424 , which is disposed on the shell 41 and communicates with the heat exchange cavity 411 through a second air outlet.
[0215] In an embodiment of the present application, the hot air conveying device 4 also includes a second air outlet pipe 424, which is arranged on the shell 41 and connected to the heat exchange chamber 411 through a second air outlet. The second air outlet pipe 424 can be conveniently assembled and connected with the structure to be installed, and can adapt to the installation requirements of different structures to be installed.
[0216] Optionally, the second air outlet pipe 424 is detachably disposed on the shell 41 , and the second air outlet pipe 424 can be disassembled and assembled as required.
[0217] As for the second air flow path, the air to be heated enters the heat exchange chamber 411 through the second air inlet pipe 423 and the second air inlet port, completes the heat exchange process in the heat exchange chamber 411, and is discharged to the outside of the heat exchange chamber 411 through the second air outlet and the second air outlet pipe 424.
[0218] Implementation Method 14
[0219] The inventors of the present application discovered that when hot air enters the heat exchange chamber 411 from the second air inlet as a heat source, when the thermal insulation performance of the shell 41 is not good enough, part of the heat will diffuse to the outside through the shell 41. This part of the heat cannot act on the air to be heated, resulting in unnecessary heat loss.
[0220] For this reason, Figure 6 As shown, the inventor of the present application proposes an improved hot air conveying device 4 in one embodiment of the present application, the main improvement of which is that a fourth insulation layer 43 is further added on the original basis, and the fourth insulation layer 43 is arranged on the shell 41 and located in the heat exchange chamber 411.
[0221] In an embodiment of the present application, a fourth thermal insulation layer 43 is provided on the inner wall of the shell 41, and the fourth thermal insulation layer 43 is used to block the heat inside the heat exchange chamber 411 from transmitting to the outside of the shell 41, so that the heat brought by the hot air as a heat source can be gathered inside the heat exchange chamber 411, thereby maximizing the heat exchange between the air to be heated and the hot air, and avoiding unnecessary heat loss.
[0222] In addition, the fourth thermal insulation layer 43 disposed inside the shell 41 can also provide structural strength support for the shell 41, thereby preventing the stress condition of the shell 41 from changing due to thermal expansion and contraction, thereby preventing the shell 41 from deforming.
[0223] Optionally, the hot air inside the heat exchange cavity 411 has a tendency to flow upward, so the fourth thermal insulation layer 43 can be arranged on the top inner wall of the shell 41, which can not only provide thermal insulation but also reduce material costs.
[0224] Optionally, the fourth heat-insulating layer 43 is disposed on the entire inner wall of the shell 41 , so that the possibility of hot air propagating to the outside of the shell 41 is reduced as much as possible, thereby further enhancing the heat exchange efficiency.
[0225] Implementation Method Fifteen
[0226] During the installation of the hot air conveying device 4 , due to the diversity of the locations to be installed, there is a need to adapt to different locations to be installed.
[0227] For this purpose, the inventors of this application have optimized the design in the above embodiments, such as Figure 6 As shown, the hot air conveying device 4 further includes a support member 44 , and the support member 44 is disposed on the housing 41 .
[0228] In the embodiment of the present application, the support member 44 is provided on the housing 41, and the housing 41 can be installed to the installation position through the support member 44. The structure of the housing 41 can be fixed, and the specific structure of the support member 44 can be adaptively adjusted according to the requirements of the installation position.
[0229] For example, the support member 44 may be a hanging structure, so that the housing 41 is hung at the location to be installed. Alternatively, the support member 44 may be a supporting leg, and the housing 41 is installed at the location to be installed, such as on the ground, through the supporting leg.
[0230] In addition, the support member 44 can also realize the suspended setting of the shell 41, so that the support member 44 does not directly contact the installation position, thereby avoiding the potential safety hazard caused by the heat transmission to the outside.
[0231] Optionally, the support member 44 is disposed on the bottom wall of the housing 41 .
[0232] In an embodiment of the present application, the support member 44 is arranged on the bottom wall of the shell 41, and the support member 44 can be supported on the ground. At this time, the shell 41 as a whole is suspended relative to the ground, so that there is an assembly space between the shell 41 and the ground. When the second air inlet pipe 423 located at the bottom needs to be connected to the second air inlet port, it can provide assembly space for the second air inlet pipe 423, and can also improve the compactness of the overall structure of the hot air conveying device 4.
[0233] In a specific embodiment, the waste regeneration and processing equipment is used for recycling carbon fiber reinforced composite materials, wherein the waste regeneration and processing equipment includes a superheated steam generator 2, a regeneration processing furnace 1, a heat conversion combustion furnace 3 and a hot air conveying device 4, wherein, in order to achieve gas transmission and flow regulation, high temperature resistant pipes, flanges, valves and other structures are arranged between the above components. In order to achieve controllable regulation of the regeneration processing equipment, a control component is also provided.
[0234] During the operation of the waste recycling and treatment equipment, water is first passed through the superheated steam generator 2 to heat the water to generate saturated steam, and then the saturated steam is heated to become high-temperature superheated steam at 400°C-700°C at normal pressure with an oxygen content of less than 0.3%. The superheated steam is passed into the recycling and treatment furnace 1 through a pipeline. These superheated steams at 400°C-700°C with a small amount of oxygen and normal pressure are used as a heating heat source and an oxygen-free protective medium to perform oxygen-free protection and heating on the carbon fiber reinforced composite material (CFRP) waste in the recycling and treatment furnace 1. The heating time is 1 to 6 hours, so that the resin matrix in the carbon fiber reinforced composite material (CFRP) waste is completely gasified, and the carbon fiber filaments and the matrix resin in the carbon fiber reinforced composite material (CFRP) waste are separated. At this time, the temperature in the regeneration furnace 1 is controlled at 400℃-500℃, and hot compressed air is input. The carbon deposit on the surface of the gasified carbon fiber reinforced composite material (CFRP) waste is completely removed by the high-temperature air heat flow. The recycled regenerated carbon fiber has no carbon deposit residue and the surface is clean. The strength of the recycled regenerated carbon fiber can reach more than 90% of the original carbon fiber. The combustible organic small molecule gas decomposed by the matrix resin in the regeneration furnace 1 enters the heat conversion combustion furnace 3 through a high-temperature resistant pipeline. The heat source of about 900℃ generated after combustion enters the superheated steam generator 2 and the regeneration furnace 1 through a pipeline and a valve as a heating heat source, which greatly saves the cost of carbon fiber recovery. At the same time, the heat source generated after the heat conversion combustion furnace 3 is clean gas, which can be discharged directly. In addition, a fully automatic feeding, discharging and unloading device is designed, which can be used for large-scale industrial production.
[0235] It is worth noting that the waste regeneration and processing equipment provided in the present application can recycle carbon fiber reinforced composite material (CFRP) waste into carbon fiber raw fibers without oxidation or combustion. The surface of the carbon fiber raw fibers is clean and free of carbon deposits, and the mechanical properties are maintained at more than 90%, thus realizing the reuse of high-value materials.
[0236] At the same time, the combustible organic small molecule gas produced by the thermal decomposition of carbon fiber reinforced composite material (CFRP) waste can be recycled, which greatly saves the cost of recycling carbon fiber and achieves zero emission and zero pollution of equipment.
[0237] Below, the recycling process of waste recycling equipment is described in detail:
[0238] The first step: putting the fiber reinforced composite waste into the material cart 121, the material cart enters the regeneration furnace 1, and the furnace door is closed.
[0239] Step 2: Set the temperature of the heat energy conversion combustion furnace 3 to 900°C, ignite the natural gas through the second burner 313, and heat it to 900°C.
[0240] Step 3: The superheated steam temperature of the superheated steam generator 2 is adjusted to a set temperature (400° C.-700° C.) through the control component 118.
[0241] Step 4: Pass water into the superheated steam generator 2 to heat the water to produce saturated steam, and then heat the saturated steam to become high-temperature superheated steam of a set temperature (400°C-700°C).
[0242] Step 5: Heat the regeneration treatment furnace 1. After the temperature reaches about 100°C, superheated steam of a set temperature (400°C-700°C) is introduced into the regeneration treatment furnace 1 through a pipeline.
[0243] Step 6: The amount of steam entering the regeneration furnace 1 is adjusted according to the amount of recycled fibers, so that the entire regeneration furnace 1 is filled with superheated steam.
[0244] Step 7: The temperature in the regeneration furnace 1 is adjusted to a set temperature (400°C-700°C) through the control component 118. The fiber-reinforced composite waste will be exposed to superheated steam at 400°C-700°C.
[0245] Step 8: The fiber reinforced composite waste begins to decompose in a superheated steam atmosphere at 400℃-700℃.
[0246] Step 9: Keep the temperature at 400°C-700°C for 1-6 hours. The fiber reinforced composite waste is not oxidized or burned in the regeneration treatment furnace 1 at normal pressure, and the matrix resin on the surface of the fiber reinforced composite waste is completely gasified.
[0247] Step 10: The combustible organic small molecule gas (pyrolysis gas) and superheated steam mixed gas decomposed from the fiber reinforced composite waste in the regeneration treatment furnace 1 enters the thermal energy conversion combustion furnace 3 through the fan, pipeline and valve.
[0248] Step 11: When the mixed gas is sufficient, it will replace the natural gas that originally heats the thermal energy conversion combustion furnace 3.
[0249] Step 12: After the mixed gas is completely burned in the thermal energy conversion combustion furnace 3, it becomes a clean heat source of 900°C, and enters the superheated steam generator 2 and the regeneration treatment furnace 1 through pipes and valves, serving as a heating heat source to replace the electric heating provided by the original heating device 117.
[0250] Step 13: After all the matrix resin on the surface of the fiber reinforced composite waste is gasified, there is still carbon deposit on the surface. At this time, the superheated steam is stopped in the regeneration furnace 1, and the heated compressed air can be introduced into the regeneration furnace 1 through the hot air conveying device 4 or the heat energy conversion furnace 3.
[0251] Step 14: Adjust the amount of air entering the regeneration furnace 1 according to the amount of recycled fibers.
[0252] Step 15: The temperature in the regeneration furnace 1 is controlled at 400-500° C. by the control component 118, so that the carbon deposited on the surface of the gasified fiber reinforced composite material waste is completely removed.
