Currently, common dry chemical filter media typically consists of a filter housing, filter media, and other auxiliary components.

[0003] As is well known, adsorption filters require regular replacement and maintenance of the filter media during practical applications to ensure the filtration effect. Similarly, dry chemical filter media also requires regular replacement of the filter media. Existing dry chemical filter media suffers from problems such as cumbersome and complicated replacement of the filter media and poor filtration effect.

[0004] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a dry chemical filter media.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a dry chemical filter that can perform distributed filtration of exhaust gas, simplify the filter media replacement process, and improve the filtration effect of the dry chemical filter.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A dry chemical filter media includes: a lower cylinder, a cylinder cover, a packing filter element, and a dehumidification and drying element.

[0009] A cylinder cover is fixedly installed on the upper part of the lower cylinder, and the cylinder cover and the lower cylinder cooperate to form a filter cylinder.

[0010] The packing filter component is disposed in the lower cylinder. The packing filter component includes an annular packing box, filter packing, and a support ring. The annular packing box is slidably disposed in the lower cylinder. The filter packing is filled in the annular packing box. The support ring is arranged below the annular packing box and is fixedly connected to the inner wall of the lower cylinder.

[0011] The dehumidification and drying component is fixedly installed in the lower cylinder. The dehumidification and drying component includes a limiting air guide pipe, a dehumidification filter pipe, and a dehumidification packing. The limiting air guide pipe is installed in an annular packing box. The dehumidification filter pipe is slidably installed in the limiting air guide pipe and is threadedly connected to the cylinder cover. The dehumidification packing fills the dehumidification filter pipe.

[0012] In one or more embodiments of this utility model, a gas conveying pipe is fixedly connected to the bottom of the lower cylinder. The waste gas to be treated can be conveyed into the lower cylinder for filtration through the gas conveying pipe. Several exhaust pipes are fixedly connected to the top of the cylinder cover. The treated waste gas in the lower cylinder can be discharged through these exhaust pipes.

[0013] In one or more embodiments of this utility model, the annular stuffing box includes a receiving box, a ventilation limiting filter, and an exhaust limiting filter. The outer wall of the receiving box is fitted to the inner wall of the lower cylinder. This reduces the risk of treated exhaust gas escaping from the lower cylinder.

[0014] In one or more embodiments of this utility model, the ventilation limiting filter is fixedly installed on the side of the storage box close to the limiting air guide pipe. The ventilation limiting filter and the exhaust limiting filter work together to limit and store the filter media. Simultaneously, gas can be conducted through the ventilation limiting filter and the dehumidification filter pipe. The exhaust limiting filter is fixedly installed on the top of the storage box, corresponding to the exhaust pipe. The exhaust limiting filter can be used to exhaust the filtered waste gas from the annular packing box.

[0015] In one or more embodiments of this utility model, the limiting air guide tube includes an air guide tube body and an air guide tube. The outer wall of the air guide tube body is in contact with the ventilation limiting filter screen. The air guide tube body serves to limit the assembly of the dehumidification filter tube. Multiple evenly distributed exhaust holes are provided on the overlapping portion of the air guide tube body and the ventilation limiting filter screen. This allows the dehumidified and filtered gas in the limiting air guide tube to be transported to the annular packing box along the exhaust holes.

[0016] In one or more embodiments of this utility model, the guiding air tube is integrally formed at the bottom of the guiding air tube body, and the guiding air tube is connected to the conveying air tube. The guiding air tube serves to connect the guiding air tube body and the conveying air tube, so that the waste gas conveyed in the conveying air tube can be conveyed along the guiding air tube to the limiting guiding air tube.

[0017] In one or more embodiments of this utility model, the dehumidifying filter tube includes an assembled solid tube, a driving block, and a mesh cylinder. A limiting block is integrally formed on the inner wall of the cylinder cover, and the lower bottom surface of the limiting block contacts the upper top surface of the air guide tube body. The limiting block limits the assembly of the assembled solid tube. Simultaneously, the limiting block can also seal and limit the top of the air guide tube body.

[0018] In one or more embodiments of this utility model, a mounting through hole is provided at the center of the limiting block and the cylinder cover, and the diameter of the mounting through hole is the same as the inner diameter of the air guide tube. The mounting through hole facilitates the easy assembly and disassembly of the solid tube, simplifying the process of disassembling and replacing the dehumidifying filter tube.

[0019] In one or more embodiments of this utility model, the solid assembly tube passes through the assembly through hole and is threadedly connected to the assembly through hole. The driving block is fixedly connected to one end of the solid assembly tube located outside the threaded through hole. By controlling the rotation of the driving block, the solid assembly tube can be rotated, thereby allowing the dehumidification filter tube to be disassembled and replaced by rotating in both directions via the threaded connection.

[0020] In one or more embodiments of this utility model, the mesh cylinder is fixedly disposed at the bottom of the assembled solid tube, and the dehumidifying filler is filled between the assembled solid tube and the mesh cylinder. The mesh cylinder serves to contain and limit the dehumidifying filler.

[0021] Compared with the prior art, the dry chemical filter disclosed in this utility model adopts a distributed filtration method to filter waste gas, which improves the filtration effect of waste gas and simplifies the process of replacing the filter media. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0030] like Figures 1 to 4 As shown, a dry chemical filter media according to one embodiment of this utility model includes: a lower cylinder 1, a cylinder cover 101, a packing filter component 2, and a dehumidification and drying component 3. In practical applications, the exhaust gas delivered to the lower cylinder 1 can be dehumidified and harmful gas filtered in stages by the dehumidification and drying component 3 and the packing filter component 2.

[0031] like Figure 4 As shown, a cylinder cover 101 is fixedly installed on the upper part of the lower cylinder 1, and the cylinder cover 101 and the lower cylinder 1 cooperate to form a filter cylinder. The filter cylinder provides a treatment space for the treatment of waste gas.

[0032] like Figures 1 to 4 As shown, a gas conveying pipe 4 is fixedly connected to the bottom of the lower cylinder 1. The waste gas to be treated can be conveyed into the lower cylinder 1 for filtration through the gas conveying pipe 4. Several exhaust pipes 5 are fixedly connected to the top of the cylinder cover 101. The treated waste gas in the lower cylinder 1 can be discharged through the several exhaust pipes 5.

[0033] like Figures 1 to 2 As shown, the packing filter component 2 is disposed inside the lower cylinder 1. The packing filter component 2 includes an annular packing box 201, filter media 202, and a support ring 203. The annular packing box 201 is slidably disposed inside the lower cylinder 1. The annular packing box 201 stores and collects the filter media 202, thereby facilitating the adsorption and filtration treatment of waste gas through the filter media 202.

[0034] like Figures 1 to 2As shown, the annular stuffing box 201 includes a receiving box 2011, a ventilation limiting filter 2012, and an exhaust limiting filter 2013. The outer wall of the receiving box 2011 is fitted to the inner wall of the lower cylinder 1. This reduces the risk of treated exhaust gas escaping from the lower cylinder 1.

[0035] like Figures 1 to 2 As shown, the ventilation limiting filter 2012 is fixedly installed on the side of the storage box 2011 close to the limiting air guide pipe 301. The ventilation limiting filter 2012 and the exhaust limiting filter 2013 work together to limit and retain the filter media 202. Simultaneously, gas can be exchanged between the ventilation limiting filter 2012 and the dehumidification filter pipe 302.

[0036] like Figures 1 to 2 As shown, the exhaust limiting filter 2013 is fixedly installed on the top of the storage box 2011, and the exhaust limiting filter 2013 is correspondingly installed with the exhaust pipe 5. The exhaust gas filtered in the annular stuffing box 201 can be discharged through the exhaust limiting filter 2013.

[0037] like Figure 1 As shown, the filter packing 202 is filled in the annular packing box 201, and the supporting ring 203 is arranged below the annular packing box 201 and is fixedly connected to the inner wall of the lower cylinder 1.

[0038] Specifically, the filter media 202 can be made of activated carbon or SDG acid gas adsorbent, and the filter media 202 can adsorb and treat acidic gases in the waste gas.

[0039] like Figures 1 to 3 As shown, the dehumidifying and drying component 3 is fixedly installed inside the lower cylinder 1. The dehumidifying and drying component 3 includes a limiting air guide pipe 301, a dehumidifying filter pipe 302, and a dehumidifying packing 303. The limiting air guide pipe 301 is installed inside the annular packing box 201, and the limiting air guide pipe 301 serves to limit the assembly of the dehumidifying filter pipe 302 and guide and transport the gas flow.

[0040] like Figures 1 to 3 As shown, the limiting air guide pipe 301 includes an air guide pipe body 3011 and an air guide pipe 3012. The outer wall of the air guide pipe body 3011 is in contact with the ventilation limiting filter screen 2012. The air guide pipe body 3011 serves to limit the assembly of the dehumidification filter pipe 302. Multiple evenly distributed exhaust holes are provided in the overlapping portion of the air guide pipe body 3011 and the ventilation limiting filter screen 2012. This allows the dehumidified and filtered gas in the limiting air guide pipe 301 to be transported to the annular packing box 201 along the exhaust holes.

[0041] like Figures 1 to 3As shown, the guide air tube 3012 is integrally formed at the bottom of the guide air tube body 3011, and the guide air tube 3012 is connected to the delivery air tube 4. The guide air tube 3012 serves to connect the guide air tube body 3011 and the delivery air tube 4, so that the waste gas transported in the delivery air tube 4 can be transported along the guide air tube 3012 to the limiting guide air tube 301.

[0042] like Figures 1 to 3 As shown, the dehumidifying filter tube 302 is slidably disposed within the limiting air guide tube 301 and is threadedly connected to the cylinder cover 101. The dehumidifying filter tube 302 serves to store and limit the dehumidifying packing 303, allowing the dehumidifying packing 303 to be stored through the dehumidifying filter tube 302.

[0043] like Figures 1 to 2 As shown, the dehumidification filter tube 302 includes a solid assembly tube 3021, a drive block 3022, and a mesh cylinder 3023. A limiting block 6 is integrally formed on the inner wall of the cylinder cover 101, with its lower bottom surface contacting the upper top surface of the air guide tube body 3011. The limiting block 6 limits the assembly of the solid assembly tube 3021. Simultaneously, the limiting block 6 can also seal and limit the top of the air guide tube body 3011.

[0044] Specifically, the center of the limiting block 6 and the cylinder cover 101 is provided with an assembly through hole, the diameter of which is the same as the inner diameter of the air guide tube 3011. The assembly through hole facilitates the assembly and disassembly of the solid tube 3021, simplifying the process of disassembling and replacing the dehumidifying filter tube 302.

[0045] like Figures 1 to 2 As shown, the solid tube 3021 is installed through the mounting through hole and is threadedly connected to the mounting through hole. The drive block 3022 is fixedly connected to one end of the solid tube 3021 located outside the threaded through hole. By controlling the rotation of the drive block 3022, the solid tube 3021 can be rotated, thereby allowing the dehumidification filter tube 302 to be disassembled and replaced by rotating in both directions via the threaded connection.

[0046] like Figures 1 to 2 As shown, the mesh cylinder 3023 is fixedly installed at the bottom of the assembly solid tube 3021, and the dehumidifying filler 303 is filled between the assembly solid tube 3021 and the mesh cylinder 3023. The mesh cylinder 3023 serves to contain and limit the dehumidifying filler 303.

[0047] like Figure 1 As shown, the dehumidifying packing 303 is filled inside the dehumidifying filter tube 302. The dehumidifying packing 303 can adsorb and dehumidify the moisture in the exhaust gas.

[0048] Specifically, the dehumidifying packing 303 can be made of silica gel desiccant, activated carbon filter media, or molecular sieve, which can adsorb and remove moisture from the exhaust gas.

[0049] In practical use, the waste gas to be treated can be transported along the conveying pipe 4 and the guiding pipe 3012 into the guiding pipe body 3011, where the moisture in the waste gas is adsorbed and removed by the dehumidifying packing 303. The dehumidified waste gas can be transported along the exhaust hole on the outside of the mesh cylinder 3023 and the ventilation limiting filter screen 2012 into the filter packing 202, where the acidic gases in the waste gas are adsorbed and filtered by the filter packing 202, and then discharged along the exhaust pipe 5.

[0050] When the dehumidifying filler 303 needs to be replaced, the dehumidifying filter tube 302 can be disassembled and reassembled as a whole by rotating the drive block 3022. This method allows for convenient replacement of the dehumidifying filler 303. When the filter filler 202 needs to be replaced, the annular filler box 201 can be disassembled and reassembled as a whole by removing the cover 101, thus allowing for the replacement of the filter filler 202.
