[0023] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the first water pipe 6 runs through the rear end of the spray box 1, and the second water pipe 7 runs through the top of the spray box 1. Under the action of the water pump 5, it is ensured that the water after spraying can pass through the first water pipe 6 and the second water pipe 7 and be sprayed out from the nozzle 8 again for circulating spraying.

[0024] Further Figure 3 As shown, it is worth explaining in detail that the nozzle 8 is hemispherical in design, and an electromagnetic booster valve is installed inside the nozzle 8. The hemispherical design makes the nozzle 8 have a wider spray range and a better spray effect. The electromagnetic booster valve increases the water pressure of the nozzle 8 and the spraying operation is smoother.

[0025] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a water inlet is provided on the top of the spray box 1, so that clean water can be flexibly added to the spray box 1, and a cover is threadedly connected to the bottom of the water outlet 9, which can be flexibly opened and closed to facilitate drainage after spraying.

[0028] Further as Figure 1 and Figure 3 As shown, it is worth explaining in detail that a limiting slide groove corresponding to the activated carbon adsorption plate 12 is opened on the inner wall of the filter box 11. The activated carbon adsorption plate 12 performs preliminary filtration on harmful gases in the exhaust gas, and the limiting slide groove plays a limiting guiding role, which facilitates the pulling and replacement of the activated carbon adsorption plate 12.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that the purification mechanism 15 includes a plasma treatment box 1501 fixedly connected to the other side of the second connecting pipe 14, a cathode plate 1502 is installed near the top of the inner wall of the plasma treatment box 1501, and an anode plate 1503 is installed near the bottom of the inner wall of the plasma treatment box 1501. By setting up the purification mechanism 15, harmful substances in the exhaust gas are converted into safe substances in the form of simple small molecules, thereby avoiding direct exhaust gas discharge to pollute the atmospheric environment.

[0030] This solution has the following working process: in actual use, the waste gas generated by the processing of plastic products enters the spray box 1 from the air inlet pipe 3, the water pump 5 and the nozzle 8 are turned on to cooperate, and the waste gas is circulated and sprayed, and most of the particulate impurities and some oily organic wastes in the waste gas are removed by spraying. The waste gas after spraying enters the filter box 11, and the activated carbon adsorption plate 12 performs preliminary filtration on the harmful gas in the waste gas. The waste gas after the preliminary filtration enters the plasma treatment box 1501. Under the action of the external electric field, a large number of energy-carrying electrons generated by dielectric discharge bombard the pollutant molecules in the flue gas, ionizing, dissociating and exciting them, so as to transform the complex macromolecular pollutants into simple small molecular forms of safe substances.

[0031] In summary: by arranging the water pump 5 and the nozzle 8 in coordination, the exhaust gas is circulated and sprayed, and most of the particulate impurities and some oily organic wastes in the exhaust gas are removed by spraying, which is convenient for subsequent filtration and purification; by arranging the purification mechanism 15, the harmful substances in the exhaust gas are converted into safe substances in the form of simple small molecules, avoiding the direct discharge of the exhaust gas to pollute the atmospheric environment.
