[0022] To address the technical problem that existing dust collection technologies are highly susceptible to explosions and fires caused by electrostatic discharge sparks, please refer to [link / reference needed]. Figures 1-5 This embodiment provides the following technical solution:

[0023] An antistatic filter bag for flue gas treatment includes an activated carbon adsorption layer 1 and a connecting rod 6. The connecting rod 6 is fixedly installed on the upper surface of the activated carbon adsorption layer 1, which is filled with activated carbon. An installation component 7 is fixed to the top of the connecting rod 6. A locking block 5 is installed inside the installation component 7 and is fixed to an installation ring 4. An antistatic filter bag body 2 is fixed to the bottom of the installation ring 4. The antistatic filter bag body 2 is fixed by a positioning component 3, which is fixed to the installation component 7. The installation component 7 includes a threaded hole 71, a groove 72, a slot 73, and a fixing ring 74. The threaded hole 71 is located on the fixing ring 74. Grooves 72 are provided on both sides of the fixing ring 74, and a slot 73 is provided on the inner side of the fixing ring 74. The size of the groove 72 matches the size of the locking block 5. The position of the threaded hole 71 corresponds to the position of the fixing screw 33, and the groove 72 communicates with the slot 73.

[0024] In this embodiment, the locking block 5 is placed into the slot 73 through the groove 72, and then the mounting ring 4 is rotated to limit the antistatic filter bag body 2, fixing the antistatic filter bag body 2 on the mounting component 7. With the cooperation of the locking block 5 and the slot 73, the antistatic filter bag body 2 can be quickly installed. The operation is simple and the disassembly and assembly are convenient. After the antistatic filter bag body 2 is installed, the positioning component 3 is placed inside the antistatic filter bag body 2.

[0025] The antistatic filter bag body 2 includes an antistatic layer 21, a filter bag layer 22 and a wear-resistant layer 23. The wear-resistant layer 23 is provided on the outside of the filter bag layer 22, and the antistatic layer 21 is provided on the inside of the filter bag layer 22. The antistatic layer 21 is woven from polyester filament and stainless steel conductive fiber, and the wear-resistant layer 23 is made of Oxford cloth.

[0026] In this embodiment, the wear-resistant layer 23 can improve the wear resistance of the filter bag layer 22 and increase its service life. The antistatic layer 21 can effectively conduct static electricity on the surface of the antistatic filter bag body 2, avoiding safety hazards caused by static electricity accumulation.

[0027] The positioning component 3 includes a top plate 31, an outer sleeve 32, a fixing screw 33, an inner sleeve rod 34, a movable block 35, a fixing rod 36, and a pressure plate 37. The fixing screw 33 is movably installed on the top plate 31. The fixing rod 36 is fixedly installed on both sides of the lower surface of the top plate 31. The outer sleeve 32 is movably installed on the top plate 31. The fixing rod 36 and the outer sleeve 32 are staggered. The inner sleeve rod 34 is movably installed inside the outer sleeve 32. The bottom of the inner sleeve rod 34 and the fixing rod 36 are both fixed inside the pressure plate 37. The end of the outer sleeve 32 away from the top plate 31 is fixed to the movable block 35. Antistatic needle-punched felt 38 is glued to the outside of the movable block 35. The movable block 35 is movably installed on the fixing rod 36.

[0028] In this embodiment, the wear-resistant layer 23 improves the wear resistance of the filter bag layer 22 and extends its service life. The antistatic layer 21 effectively dissipates static electricity on the surface of the antistatic filter bag body 2, preventing safety hazards caused by static accumulation. By threading the fixing screw 33 into the threaded hole 71, the pressure plate 37 presses against the antistatic filter bag body 2, fixing it directly above the activated carbon adsorption layer 1. This facilitates the adsorption of impurities from the activated carbon in the activated carbon adsorption layer 1 by the activated carbon in the activated carbon adsorption layer 1. The antistatic needle-punched felt 38... The outer sleeve 32 is pulled to move the movable block 35 upward along the fixed rod 36, which in turn causes the antistatic needle-punched felt 38 to rub against the antistatic filter bag body 2. This removes dust adhering to the surface of the antistatic filter bag body 2, preventing dust from clogging the antistatic filter bag body 2 and affecting its filtration effect. At the same time, the antistatic needle-punched felt 38 has high filtration accuracy and antistatic performance. Its fiber structure can penetrate deep into the gaps on the filter bag surface, removing dust particles on the antistatic filter bag body 2 through physical friction. Moreover, this material has high chemical stability and is suitable for dust explosion risk environments.

[0029] Working principle: In use, the locking block 5 is placed into the locking slot 73 through the groove 72, and then the mounting ring 4 is rotated to limit the antistatic filter bag body 2, fixing the antistatic filter bag body 2 onto the mounting component 7. After the antistatic filter bag body 2 is installed, the positioning component 3 is placed inside the antistatic filter bag body 2. The fixing screw 33 is threaded into the threaded hole 71. At this time, the pressure plate 37 presses against the antistatic filter bag body 2, so that the antistatic filter bag body 2 can be fixed directly above the activated carbon adsorption layer 1, completing the installation of the antistatic filter bag body 2. By pulling the outer sleeve 32, the movable block 35 moves upward along the fixed rod 36, driving the antistatic needle-punched felt 38 to rub against the antistatic filter bag body 2, removing the dust adhering to the surface of the antistatic filter bag body 2.

[0030] In summary, the antistatic filter bag used for flue gas treatment features a wear-resistant layer 23 that improves the wear resistance of the filter bag layer 22, extending its service life. The antistatic layer 21 effectively dissipates static electricity on the surface of the antistatic filter bag body 2, preventing safety hazards caused by static accumulation. By threading the fixing screw 33 into the threaded hole 71, the pressure plate 37 presses against the antistatic filter bag body 2, fixing it directly above the activated carbon adsorption layer 1. This facilitates the adsorption of impurities from the activated carbon in the activated carbon adsorption layer 1, preventing static buildup. The electrostatic needle-punched felt 38 is tightly attached to the antistatic filter bag body 2. By pulling the outer sleeve 32, the movable block 35 moves upward along the fixed rod 36, causing the antistatic needle-punched felt 38 to rub against the antistatic filter bag body 2, removing dust adhering to the surface of the antistatic filter bag body 2. This prevents dust from clogging the antistatic filter bag body 2 and affecting its filtration effect. At the same time, the antistatic needle-punched felt 38 has high filtration accuracy and antistatic performance. Its fiber structure can penetrate deep into the gaps on the filter bag surface, removing dust particles on the antistatic filter bag body 2 through physical friction. Moreover, this material has high chemical stability and is suitable for dust explosion risk environments.
