When the reactor 1 generates waste gas during production and processing, the first suction fan 9 transports the waste gas along the air inlet pipe 3 to the treatment box 2, and after water spraying, filtration, purification, adsorption, and heating, the second suction fan 10 transports the treated waste gas along the air outlet pipe 4 to the jacket of the reactor 1 to heat and keep the reactor 1 warm. When replacing or maintaining, the sealing door 5 can be removed by twisting the screw.

[0024] The water spray assembly includes a water spray pipe 16 connected to the bottom of the inner side walls on both sides of the treatment box 2, the water spray pipe 16 is sleeved with a rotating sleeve 17 at both ends of the outer surface, and the outer surfaces of the two rotating sleeves 17 are connected with rotating blades 18 at equal intervals around their surfaces. The two rotating sleeves 17 are connected to each other through a connecting plate, one end of one of the rotating sleeves 17 extends to the outside of the treatment box 2 and is installed with a first gear 13, a driving motor 15 is connected to the outer wall of the treatment box 2 through a rotating rod, and a second gear 14 is installed on the outer surface of the rotating rod, the first gear 13 and the second gear 14 are meshingly connected, an atomizing nozzle 19 is connected to the upper surface of the water spray pipe 16 and is located between the two rotating sleeves 17 at equal intervals, a water storage tank 11 is provided at the bottom of the outer wall of the treatment box 2, a water pump 12 is installed on the outer top of the water storage tank 11, the water inlet end of the water pump 12 is connected to the water storage tank 11 through a first pipe, and the water outlet end of the water pump 12 is connected to the water spray pipe 16 through a second pipe. By starting the water pump 12 to generate suction, the neutralization treatment liquid in the water tank 11 is extracted and transported to the water spray pipe 16, and then sprayed out through the atomizing nozzle 19 to mix with the exhaust gas, thereby neutralizing and purifying the harmful components in the exhaust gas. At the same time, by starting the drive motor 15 to drive the second gear 14 on the connecting rod to rotate, and under the gear meshing characteristics, the first gear 13 is driven to drive the rotating sleeve 17 to rotate under the action of the connecting plate, thereby generating an air flow vortex, driving the exhaust gas to rotate in the treatment box 2, so as to increase the residence time of the exhaust gas in the treatment box 2, so that the harmful components in the exhaust gas can be fully absorbed and purified by the neutralization treatment liquid, which is beneficial to ensure the quality of the treatment and purification.

[0025] The purification component includes fixed plates 20 which are installed in parallel and at equal intervals on the middle parts of the inner walls on both sides of the treatment box 2. The three fixed plates 20 are plugged with mounting frames 21 at equal intervals. The inner sides of the four mounting frames 21 are connected with activated carbon adsorption plates 22. The four mounting frames 21 are rotatably connected with plug rods 23 at the center positions of the inner walls on both sides.

[0029] At the same time, when the exhaust gas after the first purification treatment flows along the parallel fixed plates 20, it is secondary adsorbed and filtered through the activated carbon adsorption plate 22 to purify the exhaust gas thoroughly. Secondly, when the activated carbon adsorption plate 22 needs to be replaced and maintained, first remove the push-pull plate 7 from the treatment box 2 through the handle, and then rotate the insertion rod 23 to disengage it from the insertion hole, and then remove the activated carbon adsorption plate 22 from the inner side of the mounting frame 21 for maintenance and replacement, which reduces the operation and is convenient to use.

[0030] The purified exhaust gas is then heated by an electric heating tube 8 to form hot air, and is transported to the jacket outside the reactor 1 along the exhaust pipe 4 through a second suction fan 10 to heat and insulate the reactor 1, thereby making full use of the gas.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
