Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a reclaimed rubber waste gas purification treatment device. Background Art

[0002] The rubber refining process generates a large amount of waste gas, which contains not only VOCs but also oil mist and dust. This process produces high-volume, low-concentration waste gas. Treatment technologies for this waste gas include activated carbon adsorption, low-temperature plasma, and photocatalytic oxidation. Currently, the most established and common method for treating industrial waste gas is adsorption-desorption incineration, using activated carbon as the most common adsorbent.

[0003] Volatile organic compounds in the gas are adsorbed by adsorbents (activated carbon, zeolite molecular sieves, etc.) to purify the gas. After the adsorbent is saturated, a desorption regeneration device is used to heat the adsorbate with hot air flow to desorb the adsorbate, regenerate the adsorbent, and recycle it. However, the poor desorption efficiency in the existing technology affects the subsequent adsorption effect. The temperature is difficult to control during the desorption process. When desorbing activated carbon, the temperature cannot be too high, which may easily cause the adsorbent to catch fire and cause safety problems. The temperature cannot be too low, which may affect the regeneration effect. In addition, the use of steam desorption is prone to secondary pollution of organic condensate wastewater and has high overall energy consumption. At the same time, after desorption and incineration, particulate dust and other particles are likely to remain on the surface of the adsorption device, affecting the subsequent regeneration adsorption effect. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor desorption effect in the prior art, thereby providing a reclaimed rubber waste gas purification and treatment equipment.

[0008] An adsorption processing element, the adsorption processing element being arranged on a side of the multi-stage filter element away from the electrostatic oil removal element, the adsorption processing element comprising two adsorption elements arranged in parallel, each of the adsorption elements being connected to the multi-stage filter element via a pipeline, each of the adsorption elements comprising an adsorption chamber and an adsorption block, the adsorption block being circular and mounted in the adsorption chamber;

[0009] A desorption treatment component, the desorption treatment component is arranged between the two adsorption components and is respectively connected to the two adsorption components, the desorption treatment component includes a temperature control device, a nitrogen generator and an incineration device arranged in sequence, the nitrogen generator is connected to each adsorption component through a nitrogen delivery pipe, the temperature control device is connected to each adsorption component through a circulating air duct, the temperature control device is also connected to the incineration device, and the incineration device is also connected to an air supply pipe.

[0010] The post-processing component includes a wastewater tank and an exhaust gas treatment box which are connected in sequence. The wastewater tank and the exhaust gas treatment box are connected by a pipeline. Each of the adsorption components is connected to the wastewater tank through a pipeline. The exhaust gas treatment box is also provided with an exhaust gas discharge port at one end away from the wastewater tank.

[0011] By adopting the above technical solution, the collected waste gas is first subjected to oil smoke removal and decomposition at the electrostatic degreasing element, and then most of the dust is filtered through a multi-stage filter element, and then the organic waste gas is adsorbed by the adsorbent. The two parallel adsorbents are used alternately. After one adsorbent is saturated with adsorption, the pipeline is switched to the other adsorbent for adsorption. The saturated adsorbent is desorbed in situ. First, inert gas nitrogen is introduced through a nitrogen generator to replace the internal gas, and the pipeline and the corresponding device are replaced with a low-oxygen environment. After the replacement is completed, the temperature control device is started to perform the desorption operation of the adsorbent. The circulating gas of the temperature control device is continuously circulated and desorbed until a high concentration of organic gas is formed, and then introduced into the incineration device for incineration purification. The exhaust gas generated by the incineration is heated by the first heat exchanger and the second heat exchanger for nitrogen and air to realize waste heat utilization. This application is reasonable and effective for the waste gas treatment process, and effectively reduces energy consumption and saves costs. It fully utilizes the heat after the combustion of the waste gas. The overall process is centrally controlled, safe and reliable, and the desorption temperature is controllable, with good desorption effect.

[0012] Furthermore, the adsorption component also includes a snap-fit seat and two oppositely arranged snap-fit plates, the snap-fit seat is fixed in the adsorption chamber and arranged along the width direction of the adsorption chamber, the snap-fit seat is provided with a snap-fit groove for accommodating the adsorption block in the middle part, the adsorption block is positioned and rotatably installed in the snap-fit seat, the rotation axis of the adsorption block is vertically arranged, and a rotation drive for controlling the rotation of the adsorption block is provided on the outer side of the top of the adsorption chamber, the snap-fit plates are relatively slidingly arranged in the middle part of the snap-fit seat and the sliding direction is arranged along the width direction of the adsorption chamber, and sliding drives for controlling the sliding of the snap-fit plates are provided on opposite sides of the outside of the adsorption chamber.

[0015] By adopting the above technical solution, nitrogen is generated by a nitrogen generator and enters the device through a nitrogen delivery pipe, where gas is replaced in each pipeline and each device it passes through. When the oxygen content in the exhaust gas is less than 5%, the replacement is completed and heating and desorption can begin; the temperature control device heats the internal circulating gas and controls the gas delivery to the incineration device for incineration after the internal desorbed gas concentration meets the standard; during desorption, the nitrogen generator is continuously turned on and always delivers nitrogen to stabilize the pressure of the entire system, and finally, it is delivered into the incineration device together with the desorbed gas through the air delivery pipe.

[0016] Furthermore, the incineration device includes a mixing chamber and an incineration chamber arranged in parallel, the mixing chamber and the incineration chamber are connected by an air duct, the air duct is connected to the side wall of the mixing chamber near the top, the bottom end of the air duct is connected to the side wall of the incineration chamber near the bottom, an air supply pipe is also provided on the top of the mixing chamber, the other end of the air supply pipe is connected to a blower, and the incineration chamber is also connected to a gas delivery pipe on the side away from the mixing chamber.

[0017] By adopting the above technical solution, the desorbed gas is first introduced into the mixing chamber and mixed with preheated air, and then introduced into the incineration chamber together with the fuel gas for combustion. With the assistance of the fuel gas, the organic matter in the desorbed gas is oxidized into water, carbon dioxide and other easily treatable substances, thereby eliminating waste gas pollution.

[0018] Furthermore, a concentration sensor and a temperature sensor are provided at the circulating gas outlet. The concentration sensor is connected to the temperature control device for signal control, and the temperature sensor is connected to the air supply control valve for signal control.

[0019] By adopting the above technical solution, the concentration sensor is used to detect the nitrogen replacement situation to ensure that the oxygen content in the device and pipeline is low enough to avoid direct oxidation due to temperature during the desorption process, resulting in incomplete desorption; the temperature sensor controls the opening and closing of the air supply control valve, and the circulating gas is transported only after the temperature reaches the standard; after desorption is completed, the concentration sensor is also used to detect the concentration of organic matter in the circulating gas. After the concentration is reduced, the temperature device is adjusted to the cooling mode to remove dust and cool the inside of the adsorption element.

[0020] Furthermore, an exhaust pipe connected to the waste water tank is also provided on the top of the incineration chamber; the exhaust pipe includes a first exhaust branch pipe and a second exhaust branch pipe, the first exhaust branch pipe is connected to the waste water tank after passing through the first heat exchanger, and the second exhaust branch pipe is connected to the waste water tank after passing through the second heat exchanger.

[0021] By adopting the above technical solution, the waste gas generated by incineration is passed into the wastewater tank for condensation, and some residual gas is subsequently sent to the waste gas treatment box for treatment and discharged after the treatment is completed; the waste gas generated by incineration is used for waste heat utilization to perform heat exchange operations with the first heat exchanger and the second heat exchanger respectively.

[0023] By adopting the above technical solution, nitrogen and incineration waste gas produce heat exchange in the first heat exchanger, and the first heat exchanger heats the nitrogen entering the adsorption chamber. When the temperature of the incoming nitrogen is high, the first exhaust control valve can be used to adjust the temperature, such as closing or turning down the first exhaust control valve, reducing the working flow of the first heat exchanger or stopping it as a whole, to ensure the stability of the nitrogen entering the interior.

[0024] Furthermore, the second heat exchanger is provided with a second material inlet, a second material outlet, a second refrigerant inlet and a second refrigerant outlet, the air supply pipe includes an air supply inlet pipe and an air supply outlet pipe, the air supply inlet pipe is led out by the air blower and connected to the second material inlet, the air supply outlet pipe is connected to the second material outlet and the other end is connected to the mixing chamber, the second exhaust branch pipe includes a second exhaust branch inlet pipe and a second exhaust outlet pipe, the second exhaust branch inlet pipe is led out from the incineration chamber and connected to the second refrigerant inlet, the second exhaust outlet pipe is connected to the second refrigerant outlet and the other end is connected to the waste water tank, and the second exhaust branch inlet pipe is also provided with a second exhaust speed regulating valve.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] A reclaimed rubber waste gas purification and treatment equipment, such as Figure 1As shown, it includes a pre-treatment component 1, an adsorption treatment component 2 and a post-treatment component 10 arranged in sequence, and also includes a desorption treatment component 4 arranged between the adsorption treatment components 2. The pre-treatment component 1 includes an electrostatic oil removal component 11 and a multi-stage filter component 12 arranged in sequence, and the electrostatic oil removal component 11 and the multi-stage filter component 12 are connected by a pipeline. The adsorption treatment component 2 is arranged on the side of the multi-stage filter component 12 away from the electrostatic oil removal component 11. The adsorption treatment component 2 includes two adsorption components 3 arranged in parallel. The adsorption components 3 are all connected to the multi-stage filter component 12 through a pipeline. A three-way valve (not shown in the figure) is provided on the pipeline where the adsorption component 3 and the multi-stage filter component 12 are arranged, which can switch the working state of the two adsorption components 3. The desorption treatment component 4 is arranged between the two adsorption components 3 and is respectively connected to the two adsorption components 3. The desorption treatment component 4 includes a temperature control device 5, a nitrogen generator 6 and an incineration device 7 arranged in sequence. The post-processing unit 10 includes a wastewater tank 101 and an exhaust gas treatment tank 102, which are connected in sequence. The wastewater tank 101 and the exhaust gas treatment tank 102 are connected by a pipeline. The exhaust gas treatment tank 102 is also provided with an exhaust gas discharge port 1021 at the end away from the wastewater tank 101. Each adsorbent 3 is connected to the wastewater tank 101 by a pipeline. The pipeline connecting the adsorbent 3 and the wastewater tank 101 is equipped with an on-off valve (not shown in the figure). When a particular adsorbent 3 is desorbing, the on-off valve corresponding to that adsorbent 3 is closed.

[0038] like Figure 1 and Figure 2 As shown, each adsorption component 3 includes an adsorption chamber 31 and an adsorption block 32. The adsorption block 32 is circular and installed in the adsorption chamber 31. The adsorption block 32 is positioned and rotatably installed in the snap-fit seat 33. The rotation axis of the adsorption block 32 is vertically arranged. A rotation drive 321 for controlling the rotation of the adsorption block 32 is arranged on the outer side of the top of the adsorption chamber 31. The adsorption component 3 also includes a snap-fit seat 33 and two oppositely arranged snap-fit plates 34. The snap-fit seat 33 is fixed in the adsorption chamber 31 and is arranged along the width direction of the adsorption chamber 31. A snap-fit groove 331 for accommodating the adsorption block 32 is provided in the middle of the snap-fit seat 33. The snap-fit plate 34 is relatively slidingly arranged in the middle of the snap-fit seat 33 and the sliding direction is arranged along the width direction of the adsorption chamber 31. The snap-fit plate 34 slides back and forth relative to the adsorption chamber 31. The opposite sides outside the adsorption chamber 31 are provided with a sliding drive 341 for controlling the sliding of the snap-fit plate 34. The snap-fit seat 33 and snap-fit plate 34 are used to secure the adsorption block 32. To desorb the adsorption block 32, the snap-fit plates 34 on both sides can be loosened and the top drive 321 activated to slowly rotate the adsorption block 32. This increases the impact with the circulating gas, resulting in better desorption and a higher desorption effect, ensuring complete desorption of the adsorption block 32. During normal adsorption, the front and rear snap-fit plates 34 clamp the adsorption block 32 against each other to prevent it from shaking.

[0039] like Figure 1 and Figure 3As shown, a nitrogen inlet 311 is provided at the bottom of one end of the adsorption chamber 31, near the pretreatment element 1. This inlet 311 is connected to a nitrogen delivery pipe 61. Nitrogen, generated by a nitrogen generator 6, enters the device through the nitrogen delivery pipe 61, performing gas replacement in each pipeline and device it passes through. When the oxygen content in the exhaust gas is less than 5%, the replacement is complete, and thermal desorption can begin. During gas replacement, the subsequent incineration device 7 operates, and the gas output ensures stable internal pressure. During thermal desorption, the connection to the incineration device 7 is closed to ensure that the gas concentration meets the standard before the subsequent devices are opened.

[0040] A concentration sensor 3131 and a temperature sensor 3132 are provided at the circulating gas outlet 313. The concentration sensor 3131 is connected to the temperature control device 5 for signal control, while the temperature sensor 3132 is connected to the air supply control valve 511 for signal control. The concentration sensor 3131 is used to monitor nitrogen replacement, ensuring that the oxygen content within the device and pipeline is sufficiently low to prevent direct oxidation during the desorption process due to temperature fluctuations, which could result in incomplete desorption. The temperature sensor 3132 controls the opening and closing of the air supply control valve 511, ensuring that the circulating gas is delivered only after the temperature reaches the specified level. After desorption is complete, the concentration sensor 3131 is also used to monitor the concentration of organic matter in the circulating gas. Once the concentration decreases, the temperature control device is switched to cooling mode to remove dust and cool the interior of the adsorption element 3.

[0041] A circulating gas inlet 312 and a circulating gas outlet 313 are respectively provided near the bottom at the opposite left and right ends of the adsorption chamber 31. The circulating gas outlet 313 is located near the incinerator 7. Both the circulating gas inlet 312 and the circulating gas outlet 313 are connected to the temperature control device 5 via a circulating air duct 52. A dust removal component 53 is also provided on the circulating air duct 52 near the circulating gas outlet 313. The temperature control device 5 is also connected to the incinerator 7 via an air supply pipe 51, which is equipped with an air supply control valve 511. The temperature control device 5 heats the internal circulating gas and, after the desorbed gas concentration reaches the specified level, controls the gas flow to the incinerator 7 for incineration. During desorption, the nitrogen generator 6 is continuously operated and continuously supplies nitrogen to stabilize the pressure of the entire system. The nitrogen is ultimately delivered to the incinerator 7 through the air supply pipe 51 along with the desorbed gas. After desorption is complete, the temperature control device 5 begins to cool down and circulates again. At this time, the dust removal component 53 is activated to remove dust, reducing impurities in the circulating gas and preventing them from affecting the adsorption element 3.

[0042] The incineration device 7 includes a mixing chamber 71 and an incineration chamber 72 arranged in parallel. The mixing chamber 71 and the incineration chamber 72 are connected by an air duct 73. The air duct 73 is connected to the side wall of the mixing chamber 71 near the top, and the bottom end of the air duct 73 is connected to the side wall of the incineration chamber 72 near the bottom. An air supply pipe 74 is also provided at the top of the mixing chamber 71. The other end of the air supply pipe 74 is connected to a blower 743. A gas delivery pipe 721 is also connected to the side of the incineration chamber 72 away from the mixing chamber 71. The desorbed gas is first introduced into the mixing chamber 71 and mixed with the preheated air, and then introduced into the incineration chamber 72 together with the gas for combustion. With the assistance of the gas, the organic matter in the desorbed gas is oxidized into water, carbon dioxide and other easily treatable substances, thereby eliminating waste gas pollution.

[0043] like Figure 1 、 Figure 3 and Figure 4 As shown, an exhaust pipe 75 is also provided at the top of the incineration chamber 72, connected to the wastewater tank 101. The exhaust pipe 75 includes a first exhaust branch pipe 751 and a second exhaust branch pipe 752. The first exhaust branch pipe 751 is connected to the wastewater tank 101 after passing through the first heat exchanger 8, and the second exhaust branch pipe 752 is connected to the wastewater tank 101 after passing through the second heat exchanger 9. The exhaust gas generated by the incineration is passed into the wastewater tank 101 for condensation. Some residual gas then enters the exhaust gas treatment tank 102 for treatment and is discharged after treatment. The exhaust gas generated by the incineration is used for waste heat utilization by exchanging heat with the first heat exchanger 8 and the second heat exchanger 9, respectively.

[0044] The first heat exchanger 8 is provided with a first material inlet 81, a first material outlet 82, a first refrigerant inlet 83 and a first refrigerant outlet 84. The nitrogen delivery pipe 61 includes a nitrogen delivery inlet pipe 611 and a nitrogen delivery outlet pipe 612. The nitrogen delivery inlet pipe 611 is led out from the nitrogen generator 6 and connected to the first material inlet 81. The nitrogen delivery outlet pipe 612 is connected to the first material outlet 82 and the other end is connected to the adsorption chamber 31. The first exhaust branch pipe 751 includes a first exhaust branch inlet pipe 7511 and a first exhaust outlet pipe 7512. The first exhaust branch inlet pipe 7511 is led out from the incineration chamber 72 and connected to the first refrigerant inlet 83. The first exhaust outlet pipe 7512 is connected to the first refrigerant outlet 84 and the other end is connected to the waste water tank 101. The first exhaust branch inlet pipe 7511 is also provided with a first exhaust control valve 75111. Nitrogen and incineration exhaust gases exchange heat within the first heat exchanger 8, heating the nitrogen entering the adsorption chamber 31. When the incoming nitrogen temperature is high, the first exhaust control valve 75111 can be used to adjust the temperature. For example, closing or reducing the first exhaust control valve 75111 reduces the operating flow of the first heat exchanger 8, or even disables it entirely, to ensure stable nitrogen flow. The nitrogen delivery pipe 61 and the first exhaust branch pipe 751 only exchange heat within the first heat exchanger 8; no gas mixing occurs between the two pipes.

[0045] The second heat exchanger 9 is provided with a second material inlet 91, a second material outlet 92, a second refrigerant inlet 93 and a second refrigerant outlet 94. The air supply pipe 74 includes an air supply inlet pipe 741 and an air supply outlet pipe 742. The air supply inlet pipe 741 is led out by the air blower 743 and connected to the second material inlet 91. The air supply outlet pipe 742 is connected to the second material outlet 92 and the other end is connected to the mixing chamber 71. The second exhaust branch pipe 752 includes a second exhaust branch inlet pipe 7521 and a second exhaust outlet pipe 7522. The second exhaust branch inlet pipe 7521 is led out by the incineration chamber 72 and connected to the second refrigerant inlet 93. The second exhaust outlet pipe 7522 is connected to the second refrigerant outlet 94 and the other end is connected to the waste water tank 101. The second exhaust branch inlet pipe 7521 is also provided with a second exhaust speed regulating valve 75211. The air introduced into the second heat exchanger 9 generates heat exchange with the incineration waste gas to preheat the waste gas to be burned. The preheating flow rate can be adjusted according to the preheating situation to ensure stable preheating. The pipeline in the second heat exchanger 9 is only for heat exchange and does not cause gas mixing.

[0046] The working principle and usage of this recycled rubber waste gas purification equipment:

[0047] Exhaust gas purification: The collected exhaust gas is first subjected to oil smoke removal and decomposition at the electrostatic oil removal element 11, and then passes through the multi-stage filter element 12 to filter out most of the dust. It then passes into the adsorption treatment element 2, where an adsorption element 3 adsorbs the organic waste gas. After adsorption, the exhaust gas passes into the post-treatment element 10, where it is first condensed in the wastewater tank 101, and then passes through the exhaust treatment box 102 for targeted treatment before being discharged from the exhaust outlet 1021.

[0048] In-situ desorption: two parallel adsorbents 3 are used alternately. After one adsorbent 3 is saturated with adsorption, the pipeline is switched to the other adsorbent 3 for adsorption. The saturated adsorbent 3 is desorbed in situ, and the valve connecting the adsorbent 3 that needs to be desorbed with the multi-stage filter element 12 and the wastewater tank 101 is closed; first, inert gas nitrogen is introduced through the nitrogen generator 6 to replace the internal gas, and the pipeline and the adsorbent 3 are replaced with a low-oxygen environment. After the replacement is completed, the temperature control device 5 is started to perform the desorption operation of the adsorbent 3. The circulating gas of the temperature control device 5 is continuously circulated, heated and desorbed until a high concentration of organic gas is formed and then introduced into the incineration device Incineration purification is carried out in the device 7, and the exhaust gas generated by the incineration passes through the first heat exchanger 8 and the second heat exchanger 9 to heat the nitrogen gas and the air entering the mixing chamber 71 to realize waste heat utilization; after detecting that the organic matter concentration of the circulating gas has dropped to a certain level, heating is stopped and cooling is started. Nitrogen is continuously input and the gas is cooled under the control of the temperature control device 5, thereby controlling the cooling of the desorption accessories until the temperature drops to a certain level. The temperature control device 5, the nitrogen generator 6 and the corresponding pipeline are turned off to complete the desorption. During the cooling process, the dust removal component 53 is opened to filter and remove dust from the circulating gas to reduce impurities on the surface of the adsorption block 32.
