Energy-saving and environment-friendly multi-effect VOCs purification reactor and VOCs purification treatment method

Abstract

The invention discloses an energy-saving and environment-friendly multi-effect VOCs purification reactor. The reactor comprises an absorption liquid storage device, and a purification device main bodyis arranged at the top of the absorption liquid storage device; condensation treatment and centrifugal treatment are carried out on waste gas through a centrifugal device, so that the VOCs purification reactor can be used for removing most volatile organic compounds in the waste gas at an extremely high speed, the absorption liquid storage device, the centrifugal device and a spraying device cooperate to spray absorption liquid to the waste gas subjected to primary purification, the absorption liquid is used for further purifying the waste gas subjected to primary purification, the proportionof volatile organic compounds in the waste gas is further reduced, and through the cooperation of the purification device main body, a driving device, a poking device and an intercepting device, tertiary purification is carried out on the waste gas subjected to secondary purification so as to decompose an extremely small amount of residual volatile organic compounds in the secondary purified waste gas into harmless gas, so that the purpose of thoroughly purifying the volatile organic compounds in the waste gas is achieved, and the practicability of the VOCs purification reactor is improved.

Description

technical field [0001] The invention relates to the field of VOCs purification reactors, more specifically, to an energy-saving and environment-friendly multi-effect VOCs purification reactor and a VOCs purification treatment method. Background technique [0002] Volatile organic compounds, commonly referred to as VOCs, are usually divided into several categories such as non-methane hydrocarbons (NMHCs for short), oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs participate in the ozone in the atmospheric environment and the formation of secondary aerosols, which have an important impact on regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have unpleasant special odors, and are toxic, irritating, teratogenic and carcinogenic. Especially benzene, toluene and formaldehyde will cause great harm to human health. VOCs are important precursors that cause urban haze ...

AI Technical Summary

Problems solved by technology

[0005] Most of the existing VOCs purification reactors in the prior art only use one method to purify the waste gas containing VOCs. The purification method is too single, the purification efficiency is low, the purification is not thorough, and volatile organic compounds are likely to remain. Cause environmental pollution, especially when the content of volatile organic compounds in the exhaust gas is high, this situation is a particularly serious problem. The purpose of the present invention is to provide a kind of energy-saving and environmental protection multi-effect VOCs purification reactor and VOCs purification treatment method, which can Very good solution to the problems raised in the background technology
