Embodiment Construction
[0035] A method for controlling waste gas containing toluene volatile organic compounds, comprising the following steps:
[0036] (1) Collect the waste gas containing benzene volatile organic compounds into the chemical compressor for pressurization, and then output it after being cooled by the rear cooler of the compressor, and then send it to the separator with a cooling chamber;
[0037] (2) In the separator with a cooling chamber, the water and organic matter in the exhaust gas are separated from the steam flow, drip into the bottom of the separator under the action of gravity, and are discharged by the drain valve;
[0038] (3) The exhaust gas treated by the above steps enters the activated carbon fiber adsorption bed for adsorption treatment.
[0039] The treatment process in the separator with a cooling chamber is: 1) When passing through the angled cooling chamber, the temperature is further reduced; 2) After the exhaust gas is cooled, water, organic matter, etc. form ...

The invention discloses a method of treating waste gas containing toluene-type volatile organic compounds (VOCs). The method includes following steps: 1) collecting the waste gas toluene-type VOCs into a chemical compressor to pressurize the waste gas; 2) cooling the waste gas in a cooler in the back of the compressor and outputting the cooled gas; 3) feeding the gas into a separator having a cooling chamber, wherein water and organic substances are separated out from the gas flow in the separator having the cooling chamber and are dropped into the bottom of the separator and then discharged out through a drainage valve; and 4) feeding the treated waste gas into an activated carbon fiber adsorption bed to perform adsorption treatment. In the method, by means of combination of the tree process unit, the waste gas containing large quantity of VOCs is compressed (cooled), condensed and separated, and subjected to activated carbon fiber adsorption, thereby achieving a high comprehensive separation efficiency.
Description
technical field [0001] The invention relates to a method for treating waste gas containing toluene-like volatile organic compounds. Background technique [0002] In many industrial fields such as chemical industry, plastics and paint production, the production and processing of industrial products produce a large amount of waste gas containing volatile organic compounds. These waste gases are discharged into the atmosphere without treatment, and will form photochemical pollution under certain conditions. , affect air quality, affect the growth of animals and plants and human health, my country promulgated and implemented the "Comprehensive Emission Standards for Air Pollution" in 1997, which limits the emission limits of 33 pollutants, including volatile pollutants such as benzene, toluene, and xylene Sexual organic matter. [0003] A variety of treatment technologies are available for the treatment of waste gas containing volatile organic compounds. At present, domestic and...
