A vocs waste gas treatment system and treatment method

Abstract

The invention relates to a VOCs waste gas treatment system and treatment method, including a base, a waste gas storage tank, a condensation primary analysis device and a mixing treatment device. The waste gas storage tank is arranged on the left side of the upper end of the base, and the upper end of the base is arranged on the right side. There is a mixing treatment device, and a condensation primary analysis device is arranged between the waste gas storage tank and the mixing treatment device; the present invention condenses and precipitates the organic matter in the VOCs waste gas through the method of condensation, and reduces the concentration of the VOCs waste gas, thus solving the problem caused by the high concentration The VOCs in the VOCs will react violently and may cause combustion, which will lead to problems such as equipment damage; the invention solves the problem of excessive oxygen consumption, which causes waste and increases costs, by introducing waste gas and oxygen in equal proportions.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a VOCs waste gas treatment system and treatment method. Background technique [0002] Volatile organic compounds are often expressed as VOCs. VOCs refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or all volatile organic compounds with a vapor pressure greater than or equal to 10Pa at 20°C. organic compounds. It is usually divided into several categories such as non-methane hydrocarbons, oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs are important precursors that cause urban haze and photochemical smog, mainly from coal chemical industry, petrochemical industry, fuel coating manufacturing, solvent manufacturing and use and other processes.

AI Technical Summary

Problems solved by technology

[0003] In the process of treating VOCs waste gas, the thermal oxidation method will be used to combine VOCs to form water and carbon dioxide. First, the oxidation method can only deal with low-concentration VOCs, because higher-concentration VOCs will react violently , may cause combustion, which may cause damage to the equipment; 2. When VOCs and oxygen are fully reacted, there will often be a problem of excess oxygen, which will lead to excessive oxygen consumption, resulting in waste and increased costs.
