[0023] The combustion chamber 3 includes a combustion furnace 31, which adopts a fluidized bed combustion furnace structure. The combustion furnace 31 is connected with an air inlet pipe 32, and the air inlet pipe 32 corresponds to the position of the air inlet 2 and cooperates with each other. The combustion chamber 3 is connected to a semi-dry neutralization reaction chamber 4 through a pipeline, and the semi-dry neutralization reaction chamber 4 includes a neutralization reaction chamber 41, and the neutralization reaction chamber 41 is connected with a lime milk feed port 42, and the upper side of the lime milk feed port 42 passes through the treatment box 1. The lower end of the neutralization reaction chamber 41 is provided with a slag collecting tank 43, and the slag collecting tank 43 is slidably matched with the neutralization reaction chamber 41 to facilitate cleaning of the slag in the collection tank. In order to ensure that the exhaust gas does not leak during the treatment process, the slag collecting tank 43 is tightly connected to the neutralization reaction chamber 41. In the formula, the reaction chamber 4 is connected to the filter chamber 5 through a pipeline, wherein the pipeline is connected to an activated carbon inlet 10, and the upper end of the activated carbon inlet 10 passes through the treatment box 1. The filter chamber 5 includes a bag dust collector 51, and a dust collecting trough 52 is provided at a corresponding position on the lower side of the bag dust collector 51. The dust collecting trough 52 is funnel-shaped, which is convenient for collecting dust filtered by the bag dust collector 51. The dust collecting trough 52 is slidably connected to the bag dust collector 51, which is convenient for cleaning the dust collecting trough 52. The filter chamber 5 is connected to the induced draft fan 11 through a pipeline, and the moving mechanism 8 includes a roller 81, and a lock 82 is installed on the roller 81. The air inlet pipe 32 is connected to a delivery pipe 13, and a valve 14 is installed on the delivery pipe 13.

[0024] Working principle: Connect the delivery pipe 13 to the exhaust port of the factory, open the valve 14, and the factory exhaust gas reaches the position of the intake pipe 3 along the delivery pipe 13, and enters the combustion furnace 31 of the combustion chamber 3 through the intake pipe 32. The furnace body is composed of a porous distribution plate. A large amount of quartz sand is added to the furnace, and the quartz sand is heated to above 600°C. Hot air above 200°C is blown into the bottom of the furnace to make the hot sand boil. After the exhaust gas is added, it boils together with the hot sand. The particles in the exhaust gas are quickly dried, ignited, and burned. This process will also fully burn the gas that is not fully burned. The flue gas after combustion enters the neutralization reaction chamber 41 of the semi-dry neutralization reaction chamber 4 along the pipeline, and lime milk is added into the chamber along the lime milk feed port 42. Lime milk can remove sulfur dioxide, nitrogen monoxide, nitrogen dioxide and other polluting gases in the industrial exhaust gas. The remaining flue gas is discharged along the pipeline to the bag filter 5 in the filter chamber 5. 1. Its working principle is that the dust-containing gas enters from the air inlet, and when passing through the ash hopper, some large dust particles in the gas are separated by inertia and gravity and fall directly into the bottom of the ash hopper. After passing through the ash hopper, the dust-containing gas enters the filter bag filtering area of ​​the middle box body, and the gas passes through the filter bag, and the dust is blocked on the outer surface of the filter bag. After the purified gas enters the upper box body through the filter bag port, it is discharged from the air outlet, and the filtered dust is accumulated in the dust collecting tank 52. Under the action of the induced draft fan 11, the filtered industrial waste gas is discharged from the chimney 12. The above structures are all present in the treatment box 1. A movable roller 81 is installed on the lower side of the treatment box 1. When filtering the factory waste gas, the structure is moved to the exhaust pipe outlet, and the lock buckle 82 on the locking roller 81 is locked. The conveying pipe 13 and the exhaust pipe can be connected to treat the factory waste gas. It is easy to use and simple to operate, saves site space, and is convenient for replacement and maintenance and inspection.
