Problems solved by technology

However, due to the non-renewable characteristics of activated carbon, activated carbon needs to be replaced regularly. Generally, if the replacement is not timely, the exhaust gas will exceed the standard. At this stage, the government's environmental protection department does not approve the activated carbon adsorption process.

The system includes VOCs waste gas purification equipment and an oxidant circulation tank; the main body of the VOCs waste gas purification equipment is a tank body, the upper part of the tank body is provided with an air outlet and an oxidant inlet, and the lower part of the tank body is provided with an air inlet and a water outlet The oxidant inlet is connected to the spray plate inside the tank body; the tank body is also provided with a support tray, and the support tray is arranged above the air inlet; the liquid outlet of the oxidant circulation tank is connected to the The oxidant inlet is connected. The equipment can be used for VOCs waste gas purification treatment, and has the advantages of low operating cost and no need for regeneration and repeated replacement.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a VOCs waste gas purification system. Background technique [0002] Air pollution is one of the most prominent environmental problems in my country at present. Among them, industrial volatile organic compounds (Volatile Organic Compounds, VOCs) are one of the main sources of air pollutants. A large amount of VOCs waste gas from the chemical industry is discharged into the atmosphere, which will inevitably reduce the quality of the atmospheric environment, cause serious harm to human health, and cause huge losses to the national economy. [0003] VOCs waste gas mainly includes the following types: 1. Organic waste gas of formaldehyde; 2. Organic waste gas of benzene series such as benzene, toluene, xylene; 3. Treatment of organic waste gas of styrene and acrylic acid; 4. Treatment of waste gas of acetic acid and ethyl ester; 5. Acetone, butanone organic waste gas; 6. Oi...
