[0002] Volatile organic compounds refer to organic compounds with a relatively high saturated vapor pressure (greater than 13.33 Pa), low boiling point, small molecular weight, and easy to volatilize at room temperature under standard conditions. Such substances are one of the main pollutants in the atmosphere, commonly represented by VOC or VOCs, and total volatile organic compounds are represented by TVOC. It should be noted that VOCs do not refer to a specific pollutant, but a general term for a class of organic compounds with similar physical and chemical properties. Volatile organic compounds are usually divided into several categories such as non-methane hydrocarbons (abbreviated as NMHCs), oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, sulfur-containing organic compounds, etc. Volatile organic compounds participate in the formation of ozone and secondary aerosols in the atmospheric environment, and have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most volatile organic compounds have unpleasant special odors and have toxicity, irritation, teratogenicity, and carcinogenic effects. In particular, benzene, toluene, formaldehyde, etc. will cause great harm to human health.

[0003] Currently, when treating VOCs, a catalyst is usually used to promote the reaction between VOCs molecules and oxygen, thereby reducing the concentration of VOCs. And the existing catalyst is usually stored inside the box during use, and needs to be replaced regularly to ensure the catalytic effect. In the prior art, when installing and replacing the catalyst monomers, it is extremely easy for them to scatter, making the installation and replacement extremely difficult. Therefore, to solve the above problems, this application provides a catalyst box for treating VOCs. Utility Model Content

Slide grooves are symmetrically formed at the bottom inside the cavity. A frame is arranged inside the cavity. A plurality of notches are symmetrically formed on both sides of the frame. A catalyst body is placed inside the frame.

[0006] Preferably, the side cover covers the outside of the cavity, and the side cover is fixed to the catalytic box by bolts.

[0007] Preferably, both the gas inlet pipe and the end of the exhaust pipe extend into the cavity, and a plurality of the mounting brackets are vertically arranged inside the cavity.
