Organic waste gas combustion treatment device

Technical Field

The utility model relates to an organic waste gas treatment technical field, concretely relates to organic waste gas burning processing apparatus.

Background

Along with the development of social economy, people have stronger environmental awareness and the limit of environmental protection departments at all levels on the emission of pollutants is stricter. How to achieve harmony and unity of economic benefit and environment is a new problem facing human beings. One of the effective measures for solving the pollution source at the present stage is to treat the pollution source to minimize the pollution influence on the surrounding ecological environment, so that the total emission amount and the emission concentration of the pollution source can reach (or exceed) the requirements of corresponding national and local laws and regulations.

VOCs (volatile Organic compounds) refers to Organic compounds with saturated vapor pressure of more than 133.32Pa at normal temperature, boiling point of 50-260 ℃ below under standard atmospheric pressure of 101.3kPa, initial boiling point of 250 ℃ or below, and any volatile Organic solid or liquid at normal temperature and pressure in fire. The formation of VOCs waste gas mainly comes from road mobile source tail gas, home decoration coating, petrochemical industry, packaging printing and the like. Because acute poisoning is easily caused when the concentration of VOCs in air is too high, mild people can have symptoms such as headache, nausea and vomiting, severe people can have hepatotoxicity and even coma, and some people can be life threatening. Therefore, strict control of the emission is required for such exhaust gas.
