Description

Technical Field

[0001] The present application relates to the technical field of gas processing equipment, and in particular to a water removal device and gas processing equipment. Background Art

[0002] The synthesis and application of chlorosilane compounds is a core component of polysilicon production. The conversion and utilization of chlorosilanes relies on the introduction of a high-boiling-point cracking unit, which effectively breaks down the Si-Si bonds in chlorosilane polymers under the action of a catalyst, producing a low-boiling-point product that is easy to handle.

[0003] In existing technology, chlorine and hydrogen are typically mixed and combusted in a synthesis furnace to produce hydrogen chloride gas. However, during pipeline transportation, the small amount of water vapor carried by the hydrogen chloride gas is easily liquefied by the ambient temperature. This results in the hydrogen chloride gas containing a small amount of moisture. This presence of moisture can affect the normal operation of subsequent equipment and, in severe cases, damage production equipment. Therefore, a water removal device is required within the production equipment. However, the water removal filter element in existing water removal devices is very inconvenient to replace, and the replacement and disassembly process seriously affects processing efficiency.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] The synthesis and application of chlorosilane compounds is a core component of polysilicon production. In particular, in the high-temperature atmosphere of the reduction furnace, dichlorosilane, trichlorosilane, and silicon tetrachloride undergo polycondensation to produce chlorosilane polymers. Directly discharging these chlorosilane polymers can easily clog equipment in subsequent processes and waste the chlorosilane raw materials. The conversion and utilization of chlorosilanes relies on the introduction of a high-boiling cracking unit. This unit effectively breaks the Si-Si bonds in the chlorosilane polymers under the action of a catalyst, producing easily handled low-boiling products that can then be recovered from dichlorosilane, trichlorosilane, and silicon tetrachloride.

[0042] In the prior art, chlorine and hydrogen are usually mixed and burned in a synthesis furnace to produce hydrogen chloride gas. However, during the pipeline transportation of hydrogen chloride gas, the small amount of water vapor carried by the gas is easily liquefied by the external ambient temperature. This causes the hydrogen chloride gas to contain a small amount of moisture. The presence of this moisture can affect the normal operation of subsequent equipment and, in severe cases, can even cause damage to production equipment. Therefore, a water removal device needs to be installed in the production equipment.

[0043] However, it is very inconvenient to replace the dewatering filter element in the dewatering device in the prior art. The dewatering filter element is usually installed in a corresponding filter element cartridge and connected to the water pipe through the filter element cartridge. When replacement is required, the production equipment must first be shut down, and then the filter element cartridge must be removed from the water pipe so that the dewatering filter element can be exposed to the external environment, which is convenient for operators to disassemble and assemble. After the replacement is completed, the filter element cartridge must be connected to the water pipe again, and the machine can be started after the assembly is completed. The replacement and disassembly process seriously affects the processing efficiency.

[0044] Based on this, see Figures 1 to 5As shown, an embodiment of the present invention provides a dewatering device 10, which includes a dewatering container 100, a filter cartridge structure 200 and a dewatering filter element 300; the dewatering container 100 includes a dewatering cylinder body 110 and a dewatering cylinder cover 120, the dewatering cylinder cover 120 is detachably connected to the dewatering cylinder body 110, and the dewatering cylinder body 110 is provided with an input hole 111 and an output hole 112; the filter cartridge structure 200 is connected to the dewatering cylinder cover 120, and the filter cartridge structure 200 is provided with filter holes, which are respectively connected to the input hole 111 and the output hole 112; the dewatering filter element 300 is accommodated in the filter cartridge structure 200, and the dewatering filter element 300 is arranged between at least two filter holes, and the two filter holes are respectively connected to the input hole 111 and the output hole 112.

[0045] When using the dewatering device 10 of this embodiment, the dewatering cylinder 110 is connected to other pipes of the production equipment. By separating the dewatering cylinder cover 120, the filter cartridge structure 200 can be separated from the dewatering cylinder 110. At this time, the dewatering filter element 300 is exposed to the outside, and the operator can easily replace the dewatering filter element 300; after the dewatering filter element 300 is replaced, the dewatering cylinder cover 120 is connected to the dewatering cylinder 110 to continue operating the production equipment.

[0046] In the dewatering device 10 of this embodiment, by providing a detachable dewatering cartridge cover 120 connected to the filter cartridge structure 200, the dewatering filter element 300 can be conveniently replaced. The overall structure is simple and easy to assemble and disassemble, which effectively improves the operating efficiency of the production equipment.

[0047] Specifically, in the dewatering device 10 of the present embodiment, the input hole 111 of the dewatering container 100 is connected to the input pipe, and the output hole 112 of the dewatering container 100 is connected to the output pipe. At this time, the dewatering container 100 can be connected to the external pipe as a fixed element; because the dewatering cylinder cover 120 and the dewatering cylinder body 110 are combined in a detachable connection manner, when the dewatering filter element 300 needs to be replaced, it is only necessary to quickly separate the dewatering cylinder cover 120 from the dewatering cylinder body 110 after the production equipment is shut down, and replace the dewatering filter element 300. The disassembly and assembly efficiency of the dewatering device 10 of the present embodiment is greatly improved compared to the traditional production equipment in which the filter element cylinder is removed from the pipe as a whole and then installed. Specifically, the dewatering cylinder cover 120 and the dewatering cylinder body 110 can be combined in a detachable connection manner such as screw connection, snap connection, and threaded connection.

[0048] Specifically, the filter cartridge structure 200 includes a filter cartridge body 210 and a filter cartridge end cover 220. The filter cartridge end cover 220 is detachably connected to the filter cartridge body 210 and encloses a accommodating cavity for accommodating the dewatering filter element 300. The filter holes are connected to the accommodating cavity, and at least part of the filter holes are arranged on the filter cartridge end cover 220.

[0049] In this embodiment, filter holes are evenly distributed on the filter cartridge end cap 220, which secures the dewatering filter element 300 after being snapped onto the filter cartridge body 210. The provision of multiple filter holes effectively enhances the fluidity and filtration efficiency of gas passing through the dewatering filter element 300. The provision of a portion of the filter holes on the filter cartridge end cap 220 further improves the structural compactness of the entire device.

[0050] This design allows the dewatering filter element 300 to operate stably under high flow rates and high loads, reducing pressure fluctuations caused by moisture and thus lowering the risk of equipment failure. The removable filter cartridge end cap 220 allows for quick replacement of the dewatering filter element 300 without disassembling the entire filter cartridge structure 200. Simply removing the filter cartridge end cap 220 allows for quick installation and removal of the dewatering filter element 300, minimizing equipment downtime and improving production efficiency.

[0051] In one embodiment, the filter cartridge structure 200 also includes a filter cartridge rear wall 230, which is arranged at one end of the filter cartridge body 210 away from the filter cartridge end cover 220 to enhance the overall sealing and structural stability; the filter hole includes a first filter hole 221 and a second filter hole 231, the first filter hole 221 is arranged on the filter cartridge end cover 220, and the second filter hole 231 is arranged on the filter cartridge rear wall 230, the first filter hole 221 is correspondingly connected to the input hole 111, and the second filter hole 231 is correspondingly connected to the output hole 112.

[0052] In this embodiment, the provision of the filter cartridge rear wall 230 increases the overall strength of the filter cartridge structure 200, ensuring the efficiency and safety of the filtration process. By providing a first filter hole 221 and a second filter hole 231 on the filter cartridge end cap 220 and the filter cartridge rear wall 230, respectively, when the filter cartridge structure 200 is connected to the dewatering container 100, the first filter hole 221 can be connected to the input hole 111 to input gas to the dewatering filter element 300, and the second filter hole 231 can be connected to the output hole 112 to input the gas after water removal to the outside of the dewatering device 10. This arrangement allows HCL (hydrogen chloride) gas containing a small amount of water to circulate effectively within the filter cartridge structure 200 in a standardized flow direction, ensuring that the filtering capacity of the dewatering filter element 300 is fully utilized. Through the first filter hole 221, the entry speed of the liquid can be effectively controlled, avoiding damage to the dewatering filter element 300 or impact of particulate matter due to excessive flow rate. This not only protects the dewatering filter element 300, but also improves the service life of the entire dewatering device 10.

[0053] Furthermore, the dewatering filter element 300 is provided with a filter hole 310 , the extension direction of the filter hole 310 is parallel to the extension direction of the dewatering filter element 300 , and the length of the filter hole 310 is smaller than the length of the dewatering filter element 300 .

[0054] In a preferred embodiment, the filter hole 310 is arranged on the side facing the input hole 111. Thus, when the gas enters the dewatering filter element 300, part of the gas can first enter the filter hole 310 to increase the contact area between the gas to be filtered and the dewatering filter element 300, thereby improving the filtering effect of the dewatering filter element 300.

[0055] In one embodiment, the water removal filter element 300 includes chlorinated activated carbon.

[0056] In this embodiment, the dewatering filter element 300 may be porous activated carbon. After oxidation and acidification with concentrated sulfuric acid and nitric acid, followed by chlorination with SOCl2, chlorination functional groups are formed on the activated carbon surface. This allows the dewatering filter element 300 to selectively react with the water in the HCl gas, converting it into HCl, thereby deeply removing the water from the HCl gas. Simultaneously, the dewatering filter element 300 undergoes self-hydrolysis to generate functional groups such as surface carboxyl groups. The use of porous activated carbon effectively increases the contact area between the dewatering filter element 300 and the HCl gas, thereby enhancing the dewatering effect.

[0057] Specifically, the dewatering cylinder cover 120 includes a cover body 121 and a support member 122. The cover body 121 is detachably connected to the dewatering cylinder body 110. The support member 122 is located on the side of the cover body 121 facing the dewatering cylinder body 110, and the end of the support member 122 away from the cover body 121 is connected to the filter cartridge structure 200 so that the filter cartridge structure 200 is suspended in the dewatering cylinder body 110.

[0058] In this embodiment, the filter cartridge structure 200 and the dewatering cartridge cover 120 can be welded and fixed by the support member 122, so that when the dewatering cartridge cover 120 is connected to the dewatering cartridge body 110, the filter cartridge structure 200 is ensured to be suspended in the dewatering cartridge body 110, and the dewatering filter element 300 can be connected to the input hole 111 and the output hole 112 accordingly.

[0059] Furthermore, a handle 123 is provided on a side of the water removal cylinder cover 120 away from the water removal cylinder body 110 .

[0060] With this arrangement, when it is necessary to separate the water removal cylinder body 110 and the water removal cylinder cover 120 , the operator can hold the handle 123 and pull the water removal cylinder cover 120 , which makes disassembly and assembly convenient.

[0061] In one embodiment, the water removal cylinder 110 is provided with a positioning portion 113 . The positioning portion 113 is connected to the inner wall of the water removal cylinder 110 , and the positioning portion 113 is disposed in close contact with the outer wall of the filter cartridge structure 200 .

[0062] In this embodiment, by providing the positioning portion 113 to cooperate with the outer wall of the filter cartridge structure 200, when the water removal cartridge cover 120 is connected to the water removal cartridge body 110, the positioning portion 113 can contact the outer side of the filter cartridge structure 200 to position the filter cartridge structure 200, such as Figures 1 to 4 In the embodiment shown, the dewatering cylinder 110 is a cylindrical structure. In the process of connecting the dewatering cylinder cover 120 and the dewatering cylinder 110, it is necessary to manually match the filter holes with the input hole 111 and the output hole 112 respectively, which is difficult to operate. In this embodiment, by providing a positioning portion 113 in the dewatering cylinder 110, it is convenient to position the filter cartridge structure 200; when the filter cartridge structure 200 is a cylindrical structure, the positioning portion 113 can be an arc-shaped structure, and the arc surface of the positioning portion 113 is fitted with the filter cartridge structure 200, so as to limit the rotation of the filter cartridge structure 200 along the central axis of the dewatering cylinder 110, so as to ensure that the first filter hole 221 can be accurately aligned with the input hole 111 after the dewatering cylinder cover 120 is connected to the dewatering cylinder 110 (the second filter hole 231 is aligned with the output hole 112 in the same way).

[0063] Furthermore, there are multiple water removal filter elements 300 , and the multiple water removal filter elements 300 are arranged in sequence.

[0064] Specifically, the sequential arrangement of multiple dewatering filter cartridges 300 increases the contact area for gas filtration, allowing gas to fully interact with the filter medium of each dewatering filter cartridge 300 as it passes through it. This design not only improves the efficiency of the dewatering filter cartridges 300 and enhances their dewatering effectiveness, but also reduces the load on each dewatering filter cartridge 300, thereby extending its service life. Specifically, the number of dewatering filter cartridges 300 can be two, three, or more, and this is not a single limitation.

[0065] During the simultaneous dewatering process, multiple dewatering filters 300 effectively reduce pressure loss during the filtration process. Each filter 300 shares a portion of the filtration work, significantly reducing the risk of clogging due to excessive flow compared to a single filter 300 design. This feature maintains system flow stability, effectively preventing damage to the filter 300 or increased replacement frequency due to excessive pressure, further reducing maintenance costs and operating time.

[0066] The present invention also provides a gas processing device 1, which includes a filter 20, a compressor 30, a cracking device 40 and a water removal device 10 in any of the above embodiments; the filter 20 is used to filter hydrogen chloride gas; the compressor 30 is connected to the filter 20; the cracking device 40 is connected to the side of the compressor 30 away from the filter 20; the water removal device 10 is respectively connected to the filter 20 and the compressor 30.

[0067] It can be understood that in the gas processing equipment 1 of this embodiment, by providing the dewatering device 10 of any of the above-mentioned embodiments, the dewatering device 10 of this embodiment is connected to the filter cartridge structure 200 by providing a removable dewatering cartridge cover 120, which allows for convenient replacement of the dewatering filter element 300. The overall structure is simple and easy to assemble and disassemble, effectively improving the operating efficiency of the gas processing equipment 1. In this embodiment, the gas processing equipment 1 can be connected to a polysilicon production line, and the dewatered HCl gas output by the gas processing equipment 1 can be used in polysilicon processing production.

[0068] In one embodiment, there are multiple groups of water removal devices 10, and the multiple groups of water removal devices 10 are arranged in parallel. The gas processing equipment 1 also includes a switching valve 50, which is respectively connected to the multiple water removal devices 10 and is used to switch each water removal device 10 on and off.

[0069] In this embodiment, by setting a switching valve 50 to be connected to multiple dehydration devices 10 respectively, during the operation of the gas processing equipment 1, when it is necessary to replace the dehydration filter element 300 in a certain dehydration device 10, the gas circuit can be switched to the dehydration device 10 of another circuit through the switching valve 50, and the circuit that needs to replace the dehydration filter element 300 is disconnected. At this time, the gas processing equipment 1 can replace the filter element without stopping. Of course, in some embodiments, the gas processing equipment 1 can have at least two dehydration devices 10 to transport gas at the same time, and at least one dehydration device 10 is in a disconnected state. With this arrangement, when it is necessary to replace the dehydration device 10 that is transporting gas, it is only necessary to connect the gas to the disconnected dehydration device 10. Specifically, the number of dehydration devices 10 can be two, three, or more than three, and is not limited here.
