[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This device improves the efficiency of post-processing deodorization of plastic particles. Pure water, pressurized by a booster pump, is injected into the tank along a conveyor coil. After mixing with the high-temperature air inside the oven, a gas-liquid two-phase interface is formed. VOC molecules are easily adsorbed by water molecules and ultimately vaporized, carried out of the oven by the airflow, and enter the environmental treatment unit.

[0023] Taking the Volkswagen PV3900 test method reaching level 3.5 as an example, compared with the traditional drying method, the drying time of this solution is expected to be shortened by about 40%, and it has no negative impact on the material properties. Attached Figure Description
