[0002] With the rapid development of the plastics industry, the plastic granulation process has become an important link in plastic production. However, the waste gas generated in the plastic granulation process has a serious impact on the environment and human health. These waste gases contain a large amount of organic volatile compounds, particulate matter and other harmful substances. If they are directly discharged into the atmosphere without treatment, they will cause air pollution, water pollution and damage to the ecological balance.

[0003] Traditional methods for treating waste gas from plastic granulation mainly rely on physical adsorption and chemical absorption, but these methods often have problems such as low treatment efficiency, complex equipment, and easy clogging of filter nets. At the same time, with the increasingly stringent environmental regulations and the public's increasing awareness of environmental protection, the requirements for plastic granulation waste gas treatment technology are also getting higher and higher.

A water storage chamber 10 is provided at the bottom of the processing box 1 , and a discharge pipe 20 is connected to one side of the bottom of the water storage chamber 10 .

[0022] The utility model is provided with a filter assembly, and the spray head 7 sprays the treatment liquid evenly onto the filter screen plate 14 and the exhaust gas, and the treatment liquid reacts with the harmful substances in the exhaust gas, effectively removing the pollutants in the exhaust gas, so that the exhaust gas is significantly purified before being discharged, and most of the particulate matter and harmful substances are trapped on the filter screen plate 14, ensuring the cleanliness of the exhaust gas. At the same time, the rotating design of the filter screen frame 21 makes the exhaust gas evenly distributed between the filter screen plates 14, and can also effectively prevent the filter screen frame 21 from being blocked. When too much particulate matter accumulates on some filter screen plates 14, the rotating operation can transfer it to other positions to ensure the smooth progress of the entire filtering process, and the filter screen plate 14 located below can react with the treatment liquid sprayed by the spray head 7 and flush the impurities in the filter screen plate 14 into the water storage chamber 10, and the waste liquid carrying some impurities falls into the water storage chamber 10 through the filter screen plate 14, and then is discharged from the treatment box 1 through the discharge pipe 20.

[0023] In some embodiments of the utility model: annular grooves 12 are provided on both sides of the processing box 1, a sliding ring 13 is slidably connected in the annular grooves 12, and a filter frame 21 is arranged between the two sliding rings 13, and the driving device includes a driving motor 18 arranged on the outside of the processing box 1 and a driven gear block 15 arranged around the outside of the sliding ring 13, and the output end of the driving motor 18 passes through the processing box 1 and is connected to a driving gear 16 that matches the driven gear block 15.

[0024] In some embodiments of the present utility model: a liquid level sensor 17 is arranged on one side of the water storage chamber 10 , and one end of the discharge pipe 20 passing through the processing box 1 is connected to the discharge pump device 11 .

[0025] In some embodiments of the present invention, the filter frame 21 is hexagonal, and a dry air flow pipe 8 is obliquely connected to one side of the processing box 1 , and an output end of the dry air flow pipe 8 is connected to a nozzle 9 corresponding to one side of the filter frame 21 .

[0026] In some embodiments of the present utility model: a support plate is arranged on one side of the top of the water storage chamber 10, and a support rod for supporting the jet head 9 is arranged on the top of the support plate.

[0028] The use of the plastic granulation waste gas treatment device of the utility model is as follows:

[0029] First, open the air inlet pipe 5 to introduce the waste gas generated during the plastic granulation process into the treatment box 1. The waste gas enters the treatment box 1 under the guidance of the air inlet pipe 5, and the injection pipe 6 transports the treatment liquid to the spray head 7. The spray head 7 sprays the treatment liquid evenly onto the filter screen 14 and the waste gas. The treatment liquid reacts with the harmful substances in the waste gas to further purify the waste gas. The waste gas is filtered by the filter screen 14 in the filter screen frame 21, and most of the particulate matter and harmful substances are trapped on the filter screen 14. The waste gas treated by spraying rises upward and moves to the exhaust pipe 19 through the filter screen 14. At this time, The harmful substances have been greatly reduced, and the exhaust pipe 19 is discharged from the treatment box 1. When in use, the filter frame 21 can be rotated by the driving device. On the one hand, this arrangement makes the exhaust gas evenly distributed between the filter screen plates 14, and on the other hand, it avoids clogging of the filter screen frame 21, resulting in the filter screen frame 21 being unable to filter the exhaust gas. After the treatment liquid sprayed by the spray head 7 reacts with the exhaust gas, the water carries some impurities and falls into the water storage chamber 10 through the filter screen plate 14 under the influence of gravity, and the waste liquid is discharged from the treatment box 1 by the discharge pipe 20.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
