[0002] Substances such as inks and cleaning agents used in newspaper printing will generate harmful gases such as VOCs when drying and volatilizing. These gases not only pollute the environment but also affect the health of workers. With the increasingly strict environmental protection regulations, how to effectively purify and treat these waste gases has become an urgent problem to be solved in the printing industry.

The filtering component includes a filtering box, a filtering plate, and a reagent kit. The filtering box is fixedly connected to the purification box. The filtering plate is slidably connected to the filtering box. The reagent kit is slidably connected to the filtering box and is located inside the filtering box.
