VOCS waste gas treatment device and VOCS waste gas treatment method

Abstract

The invention relates to a VOCS (Volatile Organic Compounds) waste gas treatment device, which is characterized by comprising an inlet section, a middle processing section and an outlet section, wherein the rear end of the inlet section is connected with the front end of the middle processing section; the rear end of the middle processing section is connected with the front end of the outlet section; the middle processing section comprises a first reaction chamber inlet pipeline (7), a second reaction chamber inlet pipeline (8), a reaction chamber, a first reaction chamber outlet pipeline (9), a second reaction chamber outlet pipeline (10) and an overheating outlet pipeline (11); the reaction chamber is internally provided with a first heat retainer (12), a first catalytic domain (13), a heating zone (14), a second catalytic domain (15) and a second heat retainer (16) which are arranged in leaner pattern; a closed cycle pipeline (25) is connected between the middle part of the outlet section and the middle part of the inlet section. The VOCS waste gas treatment device and a VOCS waste gas treatment method have the advantages of high treatment efficiency, peak value-eliminated emission and lower energy consumption.

Description

technical field [0001] The invention relates to a VOCS waste gas treatment device and a VOCS waste gas treatment method. Background technique [0002] At present, China's industrial development has entered a new stage, and the increasingly prominent environmental problems have affected people's normal work and life. Environmental problems have attracted more and more attention. Therefore, in this situation, it is necessary to control the emission of harmful gases in production fields such as industry and reduce its pollution to the atmospheric environment. As we all know, a large amount of organic gases that are harmful to the atmospheric environment will be produced in the process of industrial production. At present, China's atmospheric environment has been seriously polluted, and severe smog has appeared in many areas in the north. In this case, it is necessary to increase the research and development of organic waste gas treatment technology, and reduce its harm to the...

AI Technical Summary

Problems solved by technology

[0004] 1. The processing efficiency is low; the channel between the two regenerators is curved, the airflow between the regenerator and the catalytic zone is not stable, the VOCS gas is heated unevenly, and cannot be burned completely, which reduces the purity index of the exhaust gas;

[0005] 2. There is a peak value in the emission; when the VOCS exhaust gas intake direction is switched, due to the residual untreated VOCS exhaust gas in the channel, when the VOCS exhaust gas intake direction is switched, the exhaust gas purity index cannot meet the requirements, and there is a peak value

[0006] 3. High energy consumption; open preheating, resulting in a large loss of heat energy consumption during the preheating stage
