[0031] It should also be further understood that the terms "and" and "or" as used in this specification and the appended claims refer to any combination of one or more of the associated listed items and all possible combinations, and include such combinations.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.

[0033] This utility model discloses a gas filtration device, wherein, as Figure 1 and Figure 2As shown, the device includes an intake cabinet 1 and an exhaust cabinet 2; the intake cabinet 1 is positioned above the exhaust cabinet 2, and a filter screen 101 is provided between the intake cabinet 1 and the exhaust cabinet 2; two dust collection bags 3 are provided on both sides inside the intake cabinet 1, and a partition net 31 is provided around the dust collection bags 3; an air passage is formed between the adjacent partition nets 31 on the outer sides of the two dust collection bags 3; the side opening of the intake cabinet 1 is aligned with the side opening of the exhaust cabinet 2, and an intake cabinet door 11 is provided at the side opening of the intake cabinet 1; an exhaust cabinet door 21 is provided at the side opening of the exhaust cabinet 2; the side cabinet panels of the intake cabinet 1 and the exhaust cabinet 2 are connected to the exhaust cabinet 2. The side panel of the gas cabinet 2, the air inlet door 11, and the air outlet door 21 are all provided with cabinet through holes 103; a filter box 4 is provided below the filter screen 101, and a filter assembly 41 is provided inside the filter box 4; an exhaust fan 5 is provided below the filter box 4, and the exhaust fan 5 is provided with an air inlet and an air outlet; the exhaust hole provided on the filter box 4 is connected to the air inlet of the exhaust fan 5 through a vent pipe 6; a sealing plate 102 is provided at the position corresponding to the venting cavity on the air inlet door 11; a sealing plate 102 is provided at the position corresponding to the venting cavity on the side panel of the air inlet cabinet 1 opposite to the air inlet door 11.

[0034] When the exhaust fan 5 is started, it draws in gas through the air inlet. The gas then enters through the side panel of the air intake cabinet 1. The gas is then dusted by the dust removal bag 3 and filtered through the filter box 4 to completely remove impurities. The filtered gas is then output through the side panel of the exhaust cabinet 2. Since the height of the air intake cabinet 1 is comparable to the space where the racks and workbenches are located in the production workshop, when the gas filtration device is working, it can efficiently filter fine particulate matter near the ground, maintaining a high level of cleanliness in the space where the racks and workbenches are located in the production workshop to meet the environmental requirements for the generation of electronic products.

[0035] In a more specific embodiment, the through-hole size of the partition mesh 31 is smaller than the size of the cabinet through-hole 103, and the specific structure of the cabinet through-hole 103 is as follows: Figure 3 As shown. Specifically, the exhaust port of the exhaust fan 5 faces the side panel or the door 21 of the exhaust cabinet 2.

[0036] To improve ventilation efficiency and filtration effect, the through-hole size of the separator mesh 31 can be set smaller than the through-hole size of the cabinet body 103. In this case, the through-hole 103 of the cabinet body is only used for ventilation and does not have a filtration effect, while the separator mesh 31 can be used to filter larger floating objects. The air outlet of the exhaust fan 5 can be set to face the side panel or the door 21 of the exhaust cabinet 2, thereby improving the gas output efficiency and avoiding disturbance to the materials below the exhaust fan 5, thus preventing the materials below the exhaust fan 5 from entering the production workshop environment with the output gas.

[0037] To improve sealing, an L-shaped baffle 104 can be installed in the side opening of the air intake 1. The L-shaped baffle 104 consists of an extension baffle extending outward parallel to the side opening of the air intake 1 and a folding baffle folded outward. The air intake door 11 is provided with a relief groove 12 corresponding to the L-shaped baffle 104. When the air intake door 11 is closed to the side opening of the air intake 1, the L-shaped baffle 104 is embedded in the relief groove 12, thereby improving the edge effect of the air intake door 11.

[0038] Figure 2 As shown, the intake cabinet door 11 can be rotatably connected to one side of the side opening of the intake cabinet 1 via a hinge 105. Similarly, the exhaust cabinet door 21 can be rotatably connected to one side of the side opening of the exhaust cabinet 2 via a hinge 105. A locking assembly can be provided on the opposite side of the side opening of the intake cabinet 1, opposite to the hinge 105, to lock the intake cabinet door 11. Similarly, a locking assembly can be provided on the opposite side of the side opening of the exhaust cabinet 2, opposite to the hinge 105, to lock the exhaust cabinet door 21.

[0039] In a more specific embodiment, the filter box 4 is detachably disposed below the partition mesh 31. Microporous filters 7 are provided on the inner side of the side panel of the exhaust cabinet 2 and on the inner side of the exhaust cabinet door 21.

[0040] After a certain period of use, the filter material inside filter box 4 needs to be replaced to prevent a decrease in its filtration efficiency. Therefore, filter box 4 is designed to be removable, improving the ease of replacing the filter material. To further improve the filtration effect, microporous filters 7 can also be installed on the inner side of the side panel and the inner side of the exhaust door 21, as shown in the specific structure below. Figure 4 As shown, the microporous filter 7 can filter the gas output to the outside of the gas outlet 2, and can also effectively prevent impurities in the production workshop from entering the inside of the gas outlet 2.

[0041] Furthermore, such as Figure 5 As shown, the filter box 4 has a funnel-shaped cavity inside, and the filter assembly 41 is disposed inside the funnel-shaped cavity; gas is input through the opening of the funnel-shaped cavity, and the lower through hole of the funnel-shaped cavity is connected to the vent pipe 6 to discharge gas. The filter assembly 41 includes a pre-filter layer 411, a microfiber layer 412, an activated carbon layer 413, and an antibacterial coating layer 414, all stacked together.

[0042] To enhance the filtration effect of the filter box 4, a funnel-shaped cavity can be set inside the filter box 4. The filter assembly 41 is set inside the funnel-shaped cavity. The filter assembly 41 in the funnel-shaped cavity filters the input gas from top to bottom. The gas is output through the lower through-hole of the funnel-shaped cavity, and the output gas enters the exhaust fan 5 through the vent pipe 6. Figure 5 As shown, the filter assembly 41 can be further configured to include a pre-filter layer 411, a microfiber layer material layer 412, an activated carbon layer 413, and an antibacterial coating material layer 414 stacked together. The pre-filter layer 411 can be a nylon mesh, polyester fiber mesh, etc. The pre-filter layer 411 can be configured as a woven or knitted structure to intercept large particles and protect subsequent filter layers. The microfiber layer material layer 412 can be prepared using electret polypropylene fiber, glass fiber, etc.; the microfiber layer material layer 412 contains a porous structure formed by interwoven fibers, achieving a filtration efficiency of up to 99.97% for 0.3μm particles, effectively capturing fine particles in the air. The activated carbon layer 413 can be made of coconut shell activated carbon, coal-based activated carbon, etc. The activated carbon layer 413 is an activated carbon filter element or filter screen made from activated carbon particles or powder through a molding process, possessing a large specific surface area, capable of adsorbing harmful gases and odors. The antibacterial coating contains materials such as nano silver ions and photocatalysts (such as titanium dioxide). The antibacterial coating material layer 414 can be attached to the surface of the filter material by spraying, coating or other methods. The filter material can be made of polyester fiber, etc. By adding an antibacterial coating to the surface of the filter material, the antibacterial coating material layer 414 is obtained, which has the effect of inhibiting and killing bacteria and viruses such as Escherichia coli and Staphylococcus aureus.

[0043] In a more specific embodiment, a dehumidification box 8 is provided below the filter box 4; the lower through hole of the funnel-shaped cavity is connected to one end of the dehumidification box 8; the other end of the dehumidification box 8 is connected to the vent pipe 6; and a moisture-absorbing material 81 is provided inside the dehumidification box 8. Specifically, the dust collection bag 3 includes a bag body and a fiber adsorption material disposed inside the bag body. The top surface of the air inlet cabinet 1 and the bottom surface of the air outlet cabinet 2 are both configured as sealed cabinet plates.

[0044] To improve the filtration effect, a dehumidification box 8 can be installed below the filter box 4. The dehumidification box 8 can remove water vapor contained in the gas and improve the dryness of the output gas. The dehumidification box 8 is equipped with a moisture-absorbing material 81, which can be porous silica (SiO2·nH2O). The porous silica has a large number of hydroxyl groups on its surface, which mainly adsorb water molecules through physical adsorption.

[0045] Furthermore, the dust collection bag 3 can be composed of a bag body and a fiber adsorption material. The bag body has mesh holes for gas flow, and the fiber adsorption material can be cotton fiber. Furthermore, the top surface of the inlet cabinet 1 and the bottom surface of the outlet cabinet 2 can be set as sealed cabinet plates. The sealed cabinet plates do not have the ability to allow air to pass through, which can prevent dust from accumulating inside the inlet cabinet 1 and the outlet cabinet 2 and affecting the filtration effect.

[0046] This utility model discloses a gas filtration device, which includes an inlet cabinet 1 and an outlet cabinet 2. The inlet cabinet 1 is positioned above the outlet cabinet 2, and a filter screen 101 is provided between the inlet cabinet 1 and the outlet cabinet 2. Two dust collection bags 3 are provided on both sides inside the inlet cabinet 1, and a partition net 31 is provided around the dust collection bags 3. An air passage is formed between the adjacent partition nets 31 on the outer sides of the two dust collection bags 3. The side opening of the inlet cabinet 1 is aligned with the side opening of the outlet cabinet 2, and a filter screen 101 is provided at the side opening of the inlet cabinet 1. The system includes an inlet cabinet door 11 and an outlet cabinet door 21 at its side opening. Through holes 103 are provided on the side panels of the inlet cabinet 1, the outlet cabinet 2, the inlet cabinet door 11, and the outlet cabinet door 21. A filter box 4 is located below the filter screen 101, containing a filter assembly 41. An exhaust fan 5 is located below the filter box 4, with an air inlet and an air outlet. The exhaust vent on the filter box 4 is connected to the air inlet of the exhaust fan 5 via a ventilation pipe 6. The gas filtration device receives gas through the side panel of the inlet cabinet 1, filters it through the dust bag 3 and the filter box 4, and then outputs it through the side panel of the outlet cabinet 2. This efficiently filters fine particulate matter near the ground, maintaining a high level of cleanliness in the production workshop, including the areas around the machine racks and workbenches, to meet product manufacturing requirements.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application.
