Abstract

The application provides a removal device and a removal method for volatile organic compounds in industrial waste gas, wherein the removal method mainly includes five steps: pretreatment of waste gas, adsorption by high-silicon molecular sieve, oxidization by ozone, discharge of waste liquid, and discharge of purified gas. The removal method has reasonable design, simple process and convenient operation and can completely remove the volatile organic compounds.

Description

Technical field [0001] The invention belongs to the field of air pollution control, and specifically relates to a device and a method for removing volatile organic compounds in industrial waste gas. Background technique [0002] When pollutants in the atmosphere reach a certain concentration, they will cause harm to people, animals and plants. Nowadays, whether in the production process of petrochemical industry, coatings, drug synthesis, rubber, etc., or in the processes of printing, baking varnish, and degreasing of electronic components, benzene, toluene, xylene, methanol and other volatile organic compounds are released. Exhaust gas. Most of these harmful gases are flammable and explosive, and their large amounts of emissions not only have a serious impact on the local ecological environment but also on the global ecological environment. They are one of the causes of atmospheric photochemical smog, greenhouse effect and ozone layer destruction. At the same time, industrial ...
