Problems solved by technology

However, some high-concentration exhaust gas still cannot meet the standard after combustion; or for some small molecular gases, such as carbon disulfide, hydrogen sulfide and other gases, they will escape during the enrichment process and cannot be fully combusted, and sometimes produce low concentrations of nitrogen during the combustion process. Oxide and other components, can not be discharged directly

Abstract

The invention relates to the field of waste gas treatment systems, and particularly relates to an industrial volatile organic waste gas treatment system. The treatment system comprises a pretreatmentdevice, an activated carbon adsorption and concentration device, a regenerative thermal combustion device and a composite deodorization device, wherein the composite deodorization device is a box-typeintegrated device and sequentially comprises an advanced oxidation section and a physical adsorption section from a gas inlet to a gas outlet, the advanced oxidation section comprises a gas flow equalizing plate, a UV photolysis section and a photocatalysis section, and an activated carbon layer is added to the rear end of each column of lamp tubes of the UV photolysis section. Gas which is not completely combusted and decomposed can be further purified, nitric oxide and the like generated at the front end can be treated, and finally up-to-standard emission can be achieved.

Description

technical field [0001] The invention relates to the field of waste gas treatment systems, in particular to an industrial volatile organic waste gas treatment system. Background technique [0002] Volatile organic compounds (VOCs) refer to organic compounds with a saturated vapor pressure greater than 70Pa at room temperature and a boiling point below 260°C, or all organic compounds with corresponding volatility at a vapor pressure greater than or equal to 10Pa at 20°C. All walks of life will produce a certain amount of VOCs in the production process, and their emissions will cause certain harm to the environment, such as the formation of photochemical smog, the generation of secondary organic aerosols, etc.; excessive inhalation of the human body will cause headaches, nausea, fatigue and other symptoms, some The gas is carcinogenic. [0003] At present, most of the treatment methods of industrial VOCs adopt regenerative thermal combustion (RTO) or catalytic combustion. The ...
