[0026] The mobile structure 200 is arranged on the inner wall of the outer frame 1022. The mobile structure 200 includes a guide rail 201, a slider 202, a guide rod 204 and a stopper 205. The slider 202 is arranged on the outer side of the guide rail 201, the guide rod 204 is arranged inside the slider 202, and the stopper 205 is arranged on the outer end of the guide rod 204;

[0027] The sludge treatment device 300 is disposed below the air collecting hood 101 .

[0028] Furthermore, in this embodiment, a movable hinge is provided on one side of the front cover plate 1021 and the outer frame 1022, and the front cover plate 1021 and the outer frame 1022 are movably connected through the movable hinge, and the other side of the front cover plate 1021 and the outer frame 1022 are screwed, and the upper end of the outer frame 1022 is screwed to the upper cover plate 1023, and the front cover plate 1021 is convenient to open and close through the movable hinge, closed by screws, and connected to the conduit 103 through the upper cover plate 1023.

[0029] In this embodiment, the surface of the pretreatment section 1024 is provided with diversion grooves 10210, which are arranged in an array. The introduced odor is evenly divided through the diversion grooves 10210 to facilitate subsequent treatment of the odor. The surface of the biological filter section 1025 is provided with slots corresponding to the separation grooves. The interior of the biological filter is filled with one of zeolite, activated carbon, polyurethane foam or plastic sheets. By filling the biological filter with different materials, harmful components in the odor are decomposed and adsorbed by microorganisms and converted into harmless substances.

[0030] In this embodiment, the membrane separation section 1026 is designed as a microporous membrane and is made of one of the materials selected from polyethersulfone, cellulose acetate and polytetrafluoroethylene. The design of the membrane separation section 1026 utilizes the micropores on the surface of the membrane and the chemical substances to separate the odor molecules. The adsorption section 1027 is made of activated carbon, and the harmful substances remaining in the odor are adsorbed by the adsorption section 1027. The exhaust section 1028 includes a bottom plate and an exhaust fan. The bottom plate is screwed to the bottom of the outer frame 1022. Support feet are provided at the bottom of the bottom plate. The exhaust fan is embedded in the surface of the bottom plate. The bottom plate is used as the bottom of the outer frame 1022. The circulation of the odor is controlled by the exhaust fan to discharge the purified odor. The purification structure 100 is propped up by the support angle so that there is a gap between the bottom of the purification structure 100 and the ground to facilitate the discharge of gas.

[0031] In this embodiment, two guide rails 201 are set on one side of the slider 202, and the guide rod 204 is set between the two guide rails 201. The guide rail 201 and the guide rod 204 are both screwed to the outer frame 1022 and slidably connected to the slider 202. The guide rod 204 assists the movement of the slider 202 on the guide rail 201.

[0032] In this embodiment, a slide groove 206 adapted to the guide rail 201 and a through hole 203 adapted to the guide rod 204 are provided on the inner side of the slider 202. The slide groove 206 and the through hole 203 facilitate the sliding of the slider 202. The stopper 205 cooperates with the outer end thread of the guide rod 204 to facilitate the disassembly and assembly of the stopper 205. The slider 202 is respectively screwed to the biological filter tank, the membrane separation section 1026 and the adsorption section 1027 to realize the movement of the biological filter tank, the membrane separation section 1026 and the adsorption section 1027 in the outer frame 1022.

[0033] In this embodiment, the outer side of the sludge treatment device 300 is screwed connected to the mounting plate 301, the conduit 103 passes through the mounting plate 301 and is connected to the modular purification box 102, the position of the conduit 103 is stabilized by the mounting plate 301, and a valve 104 is provided between the modular purification box 102 and the conduit 103, and the connection between the purification structure 100 and the sludge treatment device 300 is controlled by the valve 104.

[0034] Specifically, when the sludge treatment device 300 is running, the generated malodorous gas is collected by the gas collecting hood 101 above, the exhaust fan is turned on by a switch or a remote control, and the malodorous gas is extracted into the purification box through the duct 103 for purification treatment. In the modular purification box 102, the malodorous gas is divided equally through the pretreatment section 1024 to facilitate more efficient treatment of the odor, and passes through the biological filter section 1025, the membrane separation section 1026 and the adsorption section 1027 in turn to filter, separate and adsorb harmful components, and the purified gas is discharged through the exhaust fan 1029.

[0035] When the purification part of the modular purification box 102 needs to be replaced, the front cover 1021 is opened, the stopper 205 at the position of the purification part to be replaced is unscrewed, and the purification part, such as the biofilter section 1025, is pulled out. The biofilter section 1025 moves along the guide rails 201 and the guide rods 204 on the outer frame 1022 through the sliders 202 on both sides until the sliders 202 are separated from the guide rails 201, and the sliders 202 are installed on both sides of the new biofilter section 1025 in advance. The sliders 202 move inward along the guide rails 201 and the guide rods 204 for replacement, and then the stopper 205 is installed to prevent the biofilter section 1025 from falling off, and the front cover 1021 is closed, so as to solve the problem that the replacement of the purification part affects the purification work efficiency;

[0036] Taking into account that the composition of sludge is different, the composition of the malodorous gas generated is also inconsistent. According to the composition of the sludge, a purification part capable of treating the malodorous gas component is set in the purification box, and personalized settings are performed to improve the purification effect.

[0037] The components of the utility model, such as the air collecting hood 101, modular purification box 102, front cover 1021, outer frame 1022, upper cover 1023, pretreatment section 1024, biological filter section 1025, membrane separation section 1026, adsorption section 1027, exhaust section 1028, exhaust fan 1029, duct 103, valve 104, guide rail 201, slider 202, guide rod 204, block 205, sludge treatment device 300, mounting plate 301, etc., are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
