Description

Technical Field

[0001] The present application relates to the technical field of material dehydrogenation, and in particular to a dehydrogenation device. Background Art

[0002] In an environment where clean energy is increasingly valued and invested in, improving the acquisition of clean energy has become an urgent problem to be solved. Solar photovoltaic power generation is one of the main ways to obtain clean energy, and granular silicon is an important material in solar photovoltaic power generation. Therefore, a large amount of granular silicon needs to be artificially prepared to meet the needs of solar photovoltaic power generation.

[0003] At present, the fluidized bed method is a common method for preparing granular silicon. Specifically, trichlorosilane is used to prepare granular silicon through a two-step disproportionation method. However, the granular silicon produced by this method has hydrogen in the form of dangling bonds on its surface. Excessive hydrogen concentration will cause hydrogen hopping, which will affect the stability and efficiency of granular silicon preparation. Therefore, after the granular silicon is prepared, the granular silicon is usually subjected to a dehydrogenation process.

[0004] However, when the existing equipment is performing the dehydrogenation process on granular silicon, there is a problem that the temperature of granular silicon in different processing steps cannot be quickly adjusted, resulting in a low efficiency of the granular silicon dehydrogenation process. At the same time, when the equipment is adjusting the temperature of the granular silicon, it consumes a high amount of equipment power consumption, resulting in a high cost of the granular silicon dehydrogenation process.

[0005] Therefore, how to improve the dehydrogenation efficiency of granular silicon and reduce the dehydrogenation cost of granular silicon is a technical problem that urgently needs to be solved in this field. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the purpose of the present application is to provide a dehydrogenation device that can improve the dehydrogenation efficiency of materials and reduce the dehydrogenation cost.

The operation channel is used to take and place a barrel. The operation channel is connected to the storage space. The dehydrogenation chamber is used to dehydrogenate the material. The dehydrogenation chamber is installed on the shell and connected to the storage space. A heating mechanism for heating the dehydrogenation chamber is installed on the dehydrogenation chamber to heat the barrel in the dehydrogenation chamber. The preset chamber includes at least one first chamber and at least one second chamber. The first chamber is used to place a barrel waiting to enter the dehydrogenation chamber. The first chamber is installed on the shell and connected to the storage space. The second chamber is used to place a heated barrel.

The drive assembly is used to drive multiple barrels to move between the first chamber, the dehydrogenation chamber, the second chamber and the operation channel respectively.

[0009] Furthermore, the dehydrogenation device includes a heat exchange element, an input pipe, an output pipe and a cooling pipe. The input pipe connects the first chamber and the second chamber; the output pipe connects the second chamber and the heat exchange element; the cooling pipe connects the heat exchange element and the first chamber, so that the heat in the second chamber is transported to the first chamber through the input pipe, and is transported from the first chamber to the heat exchange element through the output pipe.

[0010] Furthermore, a heat insulation layer is provided outside the input pipeline, the output pipeline and the cooling pipeline, and the heat insulation layer is used to keep the input pipeline, the output pipeline and the cooling pipeline warm.

[0011] Furthermore, the dehydrogenation equipment also includes a thermal insulation layer, which is located on the inner wall of the dehydrogenation chamber.

[0012] Furthermore, the dehydrogenation device further comprises a cooling component, which is located in the second chamber to cool the heated barrel in the second chamber;

[0013] Furthermore, the cooling component is a cooling pipeline with a built-in coolant, and the cooling pipeline is located on the inner wall of the second chamber.

[0014] Furthermore, the cooling component is also located in the first chamber, and the cooling pipe is located on the inner wall of the first chamber.

[0015] Furthermore, the driving assembly includes a support member and a driving member. The support member is used to support a plurality of barrels, and the support member is located in the accommodating space; the driving member is installed on the housing and connected to the support member, and the driving member drives the support member to rotate and move vertically, so that the plurality of barrels on the support member can be respectively located in the first chamber, the dehydrogenation chamber, the second chamber and the operating channel, and move among the first chamber, the dehydrogenation chamber, the second chamber and the operating channel.

[0016] Furthermore, along the rotation direction of the support, all the first chambers, the dehydrogenation chambers, all the second chambers and the operation channels are distributed in sequence.

[0017] Furthermore, the support member includes a rotating portion connected to the driving member and a plurality of bearing portions extending perpendicularly to the rotation axis of the support member, and each bearing portion is used to support a barrel.

[0018] Furthermore, the support member has a built-in cooling channel, the cooling channel at least partially extends into the bearing portion, and the cooling channel also at least partially extends into the rotating portion along the rotation axis of the support member.

[0019] The above dehydrogenation equipment can adjust the temperature of the materials in different processing steps by providing the first chamber and the second chamber, thereby improving the dehydrogenation efficiency of the materials.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0030] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 The front, rear, left, right, top and bottom shown are used to represent the front, rear, left, right, top and bottom of the dehydrogenation device 100.

[0031] like Figure 1 and Figure 2As shown, the present application provides a dehydrogenation device 100. The dehydrogenation device 100 is used to dehydrogenate a material. In the present application, the material may be granular silicon. It should be noted that the above-mentioned material may also be other materials, and the present application does not limit this.

[0032] Specifically, the present application also provides a barrel 300 , which is used to store materials so that the dehydrogenation device 100 can perform dehydrogenation treatment on the materials in the barrel 300 .

[0033] The dehydrogenation device 100 includes a housing 11, a dehydrogenation chamber 12, a preset chamber 14 and a drive assembly 15. The housing 11 is the basic frame of the dehydrogenation device 100, and is used to support the dehydrogenation chamber 12, the preset chamber 14 and the drive assembly 15. The dehydrogenation chamber 12 is used to perform a dehydrogenation process on the barrel 300. The preset chamber 14 is used to adjust the temperature of the barrel 300 so that the temperature of the material is adjusted to the temperature required for the subsequent processing steps. The drive assembly 15 is used to place the barrel 300 and drive the barrel 300 to be transferred between the housing 11, the preset chamber 14 and the dehydrogenation chamber 12.

[0034] Specifically, the housing 11 is formed with a receiving space 111, and the receiving space 111 is used for the transmission of the barrel 300, and an operating channel 112 for taking and placing the barrel 300 is opened on the housing 11, and the operating channel 112 is connected with the receiving space 111. Through the above arrangement, the barrel 300 that has not been dehydrogenated is received from the operating channel 112 into the housing 11 and transmitted to the dehydrogenation chamber 12 to dehydrogenate the material. After the dehydrogenation is completed, the barrel 300 is transported back to the operating channel 112 by the driving component 15, and then the dehydrogenated barrel 300 is taken out from the operating channel 112, thereby completing the dehydrogenation process. Repeating the above steps can continuously dehydrogenate the materials in multiple barrels 300, thereby improving the efficiency of dehydrogenation.

[0035] Specifically, the dehydrogenation chamber 12 is installed on the housing 11 and communicated with the accommodating space 111. A heating mechanism 13 for heating the dehydrogenation chamber 12 is installed on the dehydrogenation chamber 12 to heat the barrel 300 in the dehydrogenation chamber 12. Through the above arrangement, after the driving component 15 transfers the barrel 300 to the dehydrogenation chamber 12, the dehydrogenation chamber 12 is heated by the heating mechanism 13 to increase the temperature of the barrel 300, so that the heated material undergoes an oxidation reaction, thereby dehydrogenating the material in the barrel 300, thereby reducing the hydrogen content in the material to improve the purity of the material.

[0036] Exemplarily, the present application may set an exhaust valve on the dehydrogenation chamber 12. When the material in the dehydrogenation chamber 12 completes the dehydrogenation process, the exhaust valve is opened to discharge hydrogen from the dehydrogenation chamber 12 to avoid hydrogen contamination of the material again, thereby improving the quality of the dehydrogenation process.

[0037] Specifically, the preset chamber 14 is installed on the housing 11 and communicates with the accommodating space 111. Through the above configuration, the preset chamber 14 can adjust the temperature of the material in the barrel 300.

[0038] Illustratively, along the conveying direction of the barrel 300, a preset chamber 14 can be set on the side of the dehydrogenation chamber 12 that receives the barrel 300 from the operating channel 112, so that the material can be preheated in the preset chamber, so that the barrel 300 can be preheated before being transferred to the dehydrogenation chamber 12, thereby increasing the initial temperature of the material, so that the material can be more fully dehydrogenated, thereby improving the efficiency and quality of material dehydrogenation.

[0039] Illustratively, along the conveying direction of the barrel 300, a preset chamber 14 can also be set on the side of the dehydrogenation chamber 12 that conveys the barrel 300 back to the operating channel 112, so that the preset chamber 14 can cool down the barrel 300 that has completed the dehydrogenation process, so that the material in the barrel 300 can be restored to room temperature, so as to facilitate the subsequent processing of the material.

[0040] Specifically, the driving assembly 15 includes a support member 151 and a driving member 152. The support member 151 is located in the accommodating space 111, and the support member 151 is used to support multiple barrels 300. Through the above arrangement, the support member 151 can simultaneously transport multiple barrels 300 to the dehydrogenation chamber 12 and the preset chamber 14, respectively, thereby increasing the amount of materials that can be dehydrogenated in the housing 11, thereby improving the efficiency of the dehydrogenation process.

[0041] More specifically, the driving member 152 is mounted on the housing 11 and connected to the support member 151. The driving member 152 drives the support member 151 to rotate and move vertically, so that the plurality of cartridges 300 on the support member 151 can be respectively located in the preset chamber 14, the dehydrogenation chamber 12 and the operation channel 112, and move between the preset chamber 14, the dehydrogenation chamber 12 and the operation channel 112. In the present application, the direction in which the driving member 152 drives the support member 151 to move vertically is Figure 1 The above arrangement allows the preset chamber 14, the dehydrogenation chamber 12 and the operating channel 112 to all have the barrel 300, and to perform corresponding processing steps, thereby reducing the idle time of the preset chamber 14, the dehydrogenation chamber 12 and the operating channel 112, thereby improving the efficiency of the dehydrogenation process of the material.

[0042] Specifically, along the rotation direction of the support 151, at least one preset chamber 14 is provided between the dehydrogenation chamber 12 and the operating channel 112, so that the material can be adjusted to the desired temperature before or after the dehydrogenation process, thereby improving the efficiency of the dehydrogenation process.

[0043] like Figure 2and Figure 3 As shown, the support member 151 includes a rotating portion 1511 connected to the driving member 152 and a plurality of bearing portions 1512, each bearing portion 1512 being used to support a barrel 300. The plurality of bearing portions 1512 extend perpendicularly to the rotation axis of the support member 151. In the present application, the direction of the rotation axis of the support member 151 is Figure 1 Through the above arrangement, the barrel 300 is placed on the bearing part 1512, and the rotating part 1511 drives the bearing part 1512 to rotate under the drive of the driving member 152, so that the barrel 300 passes through the preset chamber 14 and the dehydrogenation chamber 12 to complete the dehydrogenation process, so that the dehydrogenation device 100 can stably perform the dehydrogenation process of the material.

[0044] Specifically, the bearing portion 1512 extends in a direction perpendicular to the rotation axis of the support member 151, so that the bearing portion 1512 remains perpendicular to the extension direction of the rotation axis of the support member 151, so that the barrel 300 can be stably placed on the bearing portion 1512, so that the barrel 300 maintains a stable position and orientation when rotating with the bearing portion 1512, thereby improving the stability of the dehydrogenation process and also improving the convenience of taking the barrel 300 out of the operating channel 112.

[0045] It should be noted that the plurality of bearing parts 1512 are evenly arranged around the rotation axis of the support member 151, that is, two adjacent bearing parts 1512 are arranged at equal angles. The number of the bearing parts 1512 corresponds to the total number of the operating channels 112, the dehydrogenation chambers 12, and the preset chambers 14, that is, the number of the bearing parts 1512 is equal to the total number of the operating channels 112, the dehydrogenation chambers 12, and the preset chambers 14.

[0046] As an embodiment, a sealing gasket 1513 is provided on each bearing portion 1512, and when each bearing portion 1512 is close to or located in the dehydrogenation chamber 12, the sealing gasket 1513 can cooperate with the inner wall of the dehydrogenation chamber 12 to seal. Through the above arrangement, when the barrel 300 is in the dehydrogenation chamber 12 for the dehydrogenation process, the sealing gasket 1513 seals the dehydrogenation chamber 12, so that the dehydrogenation chamber 12 is isolated from the external environment, which can prevent external impurities from contaminating the material undergoing the dehydrogenation process, thereby reducing the occurrence of side reactions, so as to improve the purity of the material after dehydrogenation, and further improve the quality of the dehydrogenation process. At the same time, the sealing gasket 1513 seals the dehydrogenation chamber 12, which can reduce the heat generated when the dehydrogenation chamber 12 is heated and dissipated from the dehydrogenation chamber 12, thereby improving the efficiency of the dehydrogenation process, and can also reduce the heating cost of the dehydrogenation process, thereby reducing the cost of the dehydrogenation process.

[0047] like Figure 4As shown, as an embodiment, the dehydrogenation device 100 includes a vacuum pumping assembly 16 connected to the dehydrogenation chamber 12. When the dehydrogenation chamber 12 and the sealing gasket 1513 cooperate to seal, the vacuum pumping assembly 16 vacuums the dehydrogenation chamber 12. Through the above arrangement, when the barrel 300 is placed in the dehydrogenation chamber 12 and the sealing gasket 1513 seals the dehydrogenation chamber 12, the vacuum pumping assembly 16 evacuates the dehydrogenation chamber 12 to a vacuum state, so that the partial pressure of hydrogen is reduced, which is conducive to the separation of hydrogen from the material, thereby promoting the dehydrogenation process and improving the efficiency of the dehydrogenation process.

[0048] Exemplarily, the vacuum pump assembly 16 may be a vacuum pump, which includes a rotor and an outer shell. The outer shell of the vacuum pump is provided with a connection port and is connected to the dehydrogenation chamber 12. When the dehydrogenation chamber 12 is evacuated, the rotor of the vacuum pump rotates to draw air out of the dehydrogenation chamber 12 from the connection port, so that the dehydrogenation chamber 12 is in a vacuum state.

[0049] It should be noted that the vacuum assembly 16 in the present application may also be a device of other structural forms, and the present application does not impose any limitation on this.

[0050] like Figure 2 and Figure 3 As shown, the rotating part 1511 is at least partially located outside the shell 11, and the driving member 152 is located outside the shell 11 and connected to the rotating part 1511. Through the above arrangement, the driving member 152 is arranged on the outside of the shell 11, and the part of the rotating part 1511 connected to the driving member 152 is arranged on the outside of the shell 11, and the remaining part of the rotating part 1511 is arranged in the accommodating space 111 of the shell 11, so that the driving member 152 will not interfere with each other when driving the rotating part 1511 to rotate, so that the driving member 152 can operate normally to maintain the normal operation of the dehydrogenation device 100. In addition, the part where the rotating part 1511 is connected to the driving member 152 and the driving member 152 are both located outside the shell 11, which can prevent the heat in the accommodating space 111 from affecting the part where the rotating part 1511 is connected to the driving member 152, and / or prevent the heat in the accommodating space 111 from affecting the driving member 152, thereby improving the connection stability and service life of the driving member 152 and the rotating part 1511.

[0051] Specifically, the support member 151 is provided with a cooling channel 1514, and a coolant can be introduced into the cooling channel 1514 to assist in adjusting the temperature of the support member 151. The cooling channel 1514 at least partially extends into the bearing portion 1512, and the cooling channel 1514 also at least partially extends into the rotating portion 1511 along the rotation axis of the support member 151. Through the above arrangement, the coolant flows along the cooling channel 1514 to the rotating portion 1511 and the bearing portion 1512, so that the temperature of the support member 151 can be adjusted, thereby preventing the support member 151 from being damaged by heat when the barrel 300 is transmitted, and extending the service life of the support member 151.

[0052] As an embodiment, the dehydrogenation equipment 100 further includes an auxiliary furnace chamber 17, which is used to accommodate a barrel 300. When the auxiliary furnace chamber 17 is connected to the shell 11, the auxiliary furnace chamber 17 is connected to the operating channel 112, so that the support 151 can receive the barrel 300 in the auxiliary furnace chamber 17, or the support 151 can transport the barrel 300 to the auxiliary furnace chamber 17. Through the above arrangement, the auxiliary furnace chamber 17 is connected to the operating channel 112, so that the barrel 300 can pass through the operating channel 112 from the auxiliary furnace chamber 17 and be placed in the shell 11 for the dehydrogenation process, and the barrel 300 that has completed the dehydrogenation process can also be taken out from the shell 11, reducing the number of manpower consumed in the dehydrogenation process, thereby reducing the manpower consumption cost, and improving the efficiency of the dehydrogenation process. At the same time, when the auxiliary furnace chamber 17 is connected to the shell 11, the barrel 300 is taken and placed, which can prevent the barrel 300 from tipping over during the taking and placing process, thereby improving the stability of the dehydrogenation process.

[0053] As an embodiment, the dehydrogenation device 100 further includes a rotary valve 18. The rotary valve 18 can rotate relative to the shell 11, so that the rotary valve 18 can open and close the operating channel 112, so that the rotary valve 18 can disconnect or connect the auxiliary furnace chamber 17 with the operating channel 112. Through the above arrangement, the rotary valve 18 controls the switch of the operating channel 112, so that the operating channel 112 is opened only when the barrel 300 needs to pass through the operating channel 112 to enter and exit the shell 11, and the operating channel 112 is closed in other cases, thereby reducing the interference of the external environment on the dehydrogenation process in the shell 11, so as to improve the stability and efficiency of the dehydrogenation process.

[0054] As an embodiment, the dehydrogenation equipment 100 includes a moving assembly 19 for moving the auxiliary furnace chamber 17, and the moving assembly 19 includes a fixing mechanism 191 and a driving mechanism 192 for driving the fixing mechanism 191 to rise and fall and rotate. The fixing mechanism 191 is used to fix the auxiliary furnace chamber 17, and the fixing mechanism 191 is connected to the auxiliary furnace chamber 17. When the barrel 300 needs to be placed in the shell 11 for the dehydrogenation process, the barrel 300 is placed and fixed in the auxiliary furnace chamber 17, and the fixing mechanism 191 is used to fix the auxiliary furnace chamber 17. After the auxiliary furnace chamber 17 is fixed, the driving mechanism 192 moves the auxiliary furnace chamber 17 to the operating channel 112, so that the barrel 300 is placed in the shell 11 through the operating channel 112 for the dehydrogenation step. When it is necessary to take out the barrel 300 that has completed the dehydrogenation process from the shell 11, the barrel 300 is fixed in the auxiliary furnace chamber 17, and then the fixing mechanism 191 is used to lock the auxiliary furnace chamber 17, and the driving mechanism 192 then drives the auxiliary furnace chamber 17 away from the operating channel 112. After the auxiliary furnace chamber 17 is placed stably, the fixing mechanism 191 releases the auxiliary furnace chamber 17, and then the barrel 300 is taken out of the auxiliary furnace chamber 17 to complete the dehydrogenation process of the material. Through the above arrangement, the labor cost consumed when taking and placing the barrel 300 can be further reduced, thereby reducing the cost of the dehydrogenation process. In addition, the moving component 19 can replace manpower to carry the barrel 300, thereby improving the transmission efficiency of the barrel 300, and then improving the efficiency of the dehydrogenation process.

[0055] It should be noted that the driving mechanism 192 in the present application can be a pneumatic actuator with a cylinder as the driving source, a screw transmission device with a screw as the driving source, or a mechanical arm transmission device with a motor as the driving source. The present application does not impose any restrictions on this.

[0056] As an embodiment, the heating mechanism 13 at least partially extends to the bottom of the dehydrogenation chamber 12; and / or, the heating mechanism 13 is at least partially distributed on the inner wall of the dehydrogenation chamber 12. Through the above configuration, the heating mechanism 13 is distributed around the bottom and inner wall of the dehydrogenation chamber 12, so that when the barrel 300 is placed in the dehydrogenation chamber 12 for the dehydrogenation process, the heating mechanism 13 can evenly heat the barrel 300 from all directions, thereby improving the heating efficiency and heating uniformity of the barrel 300 by the heating mechanism 13, so as to improve the efficiency and quality of the dehydrogenation process.

[0057] Exemplarily, in the present application, the center of the barrel 300 may be a hollow structure, and the heating mechanism 13 may include a heating arm 131 that moves up and down. When the barrel 300 is transferred to the dehydrogenation chamber 12, the heating arm 131 moves downward to the hollow part in the center of the barrel 300, and after the vacuum assembly 16 evacuates the dehydrogenation chamber 12, the heating mechanism 13 is started to heat the barrel 300. During heating, the heating mechanism 13 distributed on the inner wall or bottom of the dehydrogenation chamber 12 heats the barrel 300 from the outside of the barrel 300, while the heating arm 131 at the center of the barrel 300 heats the barrel 300 from the inside of the barrel 300, which can improve the heating efficiency of the barrel 300, so that the heating efficiency of the material in the barrel 300 is improved, thereby improving the efficiency and quality of the dehydrogenation process.

[0058] like Figure 5 and Figure 6 As shown, the preset chamber 14 includes at least one first chamber 141 and at least one second chamber 142. The first chamber 141 is installed on the shell 11 and communicated with the accommodating space 111. The first chamber 141 is used to place the barrel waiting to enter the dehydrogenation chamber 12; the second chamber 142 is installed on the shell 11 and communicated with the accommodating space 111, and the second chamber 142 is used to place the heated barrel 300; the second chamber 142 is communicated with the first chamber 141 to transfer the heat in the second chamber 142 to the first chamber 141.

[0059] In this embodiment, the driving assembly 15 is used to drive the plurality of cartridges 300 to move between the first chamber 141 , the dehydrogenation chamber 12 , the second chamber 142 and the operation channel 112 .

[0060] Through the above arrangement, the barrel 300 can be cooled in the second chamber 142 after the dehydrogenation process is completed. The heat generated when the barrel 300 is cooled is transmitted to the first chamber 141, which can improve the heating efficiency of the barrel 300 in the first chamber 141, thereby improving the efficiency of the dehydrogenation process of the material; the excess heat in the second chamber 142 can also be used to heat the barrel 300 of the first chamber 141, thereby reducing the power consumption required by the heating mechanism 13, thereby reducing the cost of the material during the dehydrogenation process.

[0061] Specifically, all first chambers 141, dehydrogenation chambers 12, all second chambers 142, and operation channels 112 are sequentially distributed along the rotation direction of the support 151. Through the above arrangement, the preset chamber 14 is divided into the first chamber 141 and the second chamber 142, and the first chamber 141 and the second chamber 142 can be arranged according to whether the material in the barrel 300 has undergone a dehydrogenation process, thereby adjusting the temperature of the barrel 300, so that the material can be maintained at a suitable temperature in different steps of the dehydrogenation process, thereby improving the efficiency of the material dehydrogenation process.

[0062] Exemplarily, along the conveying direction of the barrel 300, a first chamber 141 can be set on the side of the dehydrogenation chamber 12 receiving the barrel 300 from the operating channel 112, and a second chamber 142 can be set on the side of the dehydrogenation chamber 12 that conveys the barrel 300 back to the operating channel 112. Before the barrel 300 is conveyed to the dehydrogenation chamber 12, the barrel 300 is preheated by the first chamber 141 to heat the material, thereby improving the reaction efficiency of the material during dehydrogenation. After the barrel 300 completes the dehydrogenation process, the barrel 300 is cooled by the second chamber 142 so that the material returns to room temperature, thereby facilitating the subsequent processing steps of the material. Through the above-mentioned setting, the preset chamber 14 can adjust the temperature of the material whether the dehydrogenation process is completed, so that the material can be adjusted to a suitable temperature before and after the dehydrogenation process to improve the efficiency of the material dehydrogenation process.

[0063] Specifically, the dehydrogenation device 100 includes a heat exchange element 20, an input pipe 21, an output pipe 22, and a cooling pipe 23. The input pipe 21 connects the first chamber 141 and the second chamber 142, the output pipe 22 connects the first chamber 141 and the heat exchange element 20, and the cooling pipe 23 connects the heat exchange element 20 and the second chamber 142, so that the heat of the barrel 300 in the second chamber 142 is transported to the first chamber 141 through the input pipe 21, and is transported from the first chamber 141 to the heat exchange element 20 through the output pipe 22.

[0064] More specifically, the heat exchange element 20 is used to adjust the heat of the gas in the first chamber 141 and the second chamber 142. The input pipe 21 is used to transfer the heated gas from the second chamber 142 to the first chamber 141, so that the heat in the second chamber 142 is transported to the first chamber 141 through the input pipe 21. The output pipe 22 is used to transfer the heat from the first chamber 141 to the heat exchange element 20, so that the heat exchange element 20 can cool the gas transferred from the first chamber 141. The cooling pipe 23 is used to transfer the cooled gas from the heat exchange element 20 to the second chamber 142, thereby facilitating the cooling of the barrel 300 in the second chamber 142.

[0065] Through the above arrangement, heat transfer can be achieved between the first chamber 141 and the second chamber 142. When the barrel 300 that has completed the dehydrogenation process is transferred to the second chamber 142 for cooling, the heat generated by the cooling is transferred to the first chamber 141 through the input pipe 21, so that the heat can be used to heat the barrel 300 in the first chamber 141, so that the heat of the barrel 300 in the second chamber 142 during cooling can be recycled, thereby reducing the cost of the dehydrogenation process, and accelerating the preheating of the barrel 300 in the first chamber 141, thereby improving the preheating efficiency of the barrel 300 in the first chamber 141. In the present application, Figure 5The direction indicated by the dashed line with an arrow is the direction of heat transfer.

[0066] For example, in the present application, a gas device is provided on the input pipe 21, and the gas device includes a device shell, and a gas source and a blasting component are provided in the device shell. The blasting component pushes the inert gas generated in the gas source, so that the inert gas is transmitted between the heat exchange element 20, the input pipe 21, the output pipe 22 and the cooling pipe 23 along the pushing direction of the blasting component, so that the heat is transferred along the set direction, that is, the heat is transferred along the set direction. Figure 5 The inert gas may be argon.

[0067] It should be noted that the gas device may be of other structures, the gas generated by the gas device may be any gas that does not react with the material, and the gas device may also be installed at other locations, which is not limited in this application.

[0068] Exemplarily, the heat exchange element 20 in the present application includes a motor and a rotating structure (not shown), the motor drives the rotating structure to allow heat to flow between the two sides of the heat exchange element 20 to achieve heat exchange, and the rotating structure uses a cooling magnetic fluid. Through the above arrangement, the cooling magnetic fluid has a high heat resistance and can withstand the high temperature environment when the heat exchange element 20 is working, thereby extending the service life of the rotating structure, reducing the maintenance cost of the heat exchange element 20, and reducing the use cost of the dehydrogenation device 100.

[0069] As an embodiment, the outside of the input pipe 21, the output pipe 22 and the cooling pipe 23 are all provided with a heat insulation layer 24, and the heat insulation layer 24 is used to keep the input pipe 21, the output pipe 22 and the cooling pipe 23 warm. Through the above arrangement, the heat insulation layer 24 can reduce the loss of heat when it is transmitted in the input pipe 21 and the output pipe 22, so that when the barrel 300 is heated in the first chamber 141, the heat required to be provided by the dehydrogenation device 100 is reduced, so as to reduce the cost of the material during the dehydrogenation process. At the same time, the heat insulation layer 24 is provided on the outside of the cooling pipe 23, so as to prevent the cold air generated by the heat exchange element 20 from heating up in the process of flowing to the second chamber 142, thereby improving the cooling efficiency of the barrel 300 in the second chamber 142.

[0070] As an embodiment, the dehydrogenation device 100 further includes a heat-insulating layer 25, which is located on the inner wall of the dehydrogenation chamber 12, and is used to reduce the heat loss when the dehydrogenation chamber 12 is heated. Through the above configuration, the heat-insulating layer 25 can reduce the heat of the barrel 300 from escaping from the dehydrogenation chamber 12 when the dehydrogenation chamber 12 is heated, thereby reducing the energy consumption of the heating mechanism 13 when heating the barrel 300, so as to reduce the cost of the material during the dehydrogenation process.

[0071] As an embodiment, the dehydrogenation equipment 100 further includes a cooling component (not shown), which is used to cool the barrel 300. The cooling component is located in the second chamber 142 to cool the heated barrel 300 in the second chamber 142; the cooling component is a cooling pipe 23 with a built-in coolant, and the cooling pipe 23 is located on the inner wall of the second chamber 142. Through the above arrangement, when the barrel 300 is transferred to the second chamber 142, the cooling gas output by the cooling component and the heat exchange element 20 can be used to cool the barrel 300 after the dehydrogenation process is completed, so as to facilitate the barrel 300 to perform other processing steps or secondary dehydrogenation purification after the dehydrogenation process is completed, thereby improving the processing efficiency of the material. At the same time, the cooling pipe 23 is arranged on the inner wall of the second chamber 142, which can more comprehensively cool the barrel 300 in the second chamber 142, thereby improving the cooling efficiency of the barrel 300, so as to facilitate the barrel 300 to perform subsequent processing steps. In addition, after the cooling component cools down the material in the barrel 300, when the material is taken out of the barrel 300, the material with too high temperature can be prevented from reacting with the air, thereby preventing the material from being contaminated by the air for the second time, so as to improve the purity of the material after the dehydrogenation process.

[0072] As an embodiment, the cooling and cooling component is also located in the first chamber 141, and the cooling pipe 23 is located on the inner wall of the first chamber 141. The moving direction of the barrel 300 driven by the support 151 through the first chamber 141, the dehydrogenation chamber 12, and the second chamber 142 is defined as the forward direction, and the moving direction of the barrel 300 through the second chamber 142, the dehydrogenation chamber 12, and the first chamber 141 is defined as the reverse direction. Through the above arrangement, when the moving direction of the barrel 300 is reverse, the first chamber 141 is used to cool down the barrel 300 after the dehydrogenation process is completed. Therefore, the cooling and cooling component arranged on the inner wall of the first chamber 141 can cool down the barrel 300 transmitted to the first chamber 141, so that the first chamber 141 can realize the cooling function of the second chamber 142 when the support 151 moves forward when the support 151 moves in the reverse direction.

[0073] In the present application, as an optional implementation, the working steps of the dehydrogenation device 100 are as follows:

[0074] First, the barrel 300 that needs to undergo the dehydrogenation process is placed and fixed in the auxiliary furnace chamber 17. After the fixing mechanism 191 locks the auxiliary furnace chamber 17, the driving mechanism 192 is started to transfer the auxiliary furnace chamber 17 to the operating channel 112, so that the auxiliary furnace chamber 17 is connected to the operating channel 112, and then the fixing of the barrel 300 by the auxiliary furnace chamber 17 is released, so that the barrel 300 is transferred to the bearing part 1512. The rotating part 1511 drives the bearing part 1512 to descend under the drive of the driving member 152, so that the barrel 300 completely enters the accommodating space 111, and after the barrel 300 is rotated to the bottom of the first chamber 141, the barrel 300 is raised to the first chamber 141 for preheating.

[0075] During preheating, heat starts to flow from the second chamber 142 , passes through the input pipe 21 and enters the first chamber 141 , thereby assisting in heating the barrel 300 in the first chamber 141 .

[0076] After the preheating of the barrel 300 is completed, the support member 151 transfers the barrel 300 to the bottom of the dehydrogenation chamber 12, and then the supporting part 1512 is raised until the sealing gasket 1513 seals the dehydrogenation chamber 12, and then the heating mechanism 13 is started to heat the barrel 300 to perform the dehydrogenation process on the material. After the dehydrogenation is completed, the exhaust valve is opened to discharge the dehydrogenated hydrogen.

[0077] When the material completes the dehydrogenation step, the bearing part 1512 descends until the top of the barrel 300 leaves the dehydrogenation chamber 12, and then the rotating part 1511 is started to transfer the barrel 300 to the second chamber 142, and the barrel 300 is cooled in the second chamber 142. After the barrel 300 is cooled, the support 151 transfers the barrel 300 back to the operation channel 112, and then the barrel 300 is raised until the barrel enters the auxiliary furnace chamber 17. After the auxiliary furnace chamber 17 locks the barrel 300, the fixing mechanism 191 is started to lock the auxiliary furnace chamber 17, and then the barrel 300 is driven away from the operation channel 112 through the driving mechanism 192. After the auxiliary furnace chamber 17 is placed stably, the barrel 300 is taken out to complete the dehydrogenation process of the material.
