Abstract

The invention discloses an organic waste gas purifying and recovering system. The organic waste gas purifying and recovering system comprises an organic waste gas primary adsorbing and purifying system, a primary adsorbing bed desorbing system, an organic waste gas secondary adsorbing and purifying system and a secondary adsorbing bed desorbing and recovering system, wherein the organic waste gas primary adsorbing and purifying system comprises a first filter, a first fan, a first primary adsorbing bed, a second primary adsorbing bed and a third primary adsorbing bed; the first filter, the first fan, the first primary adsorbing bed, the second primary adsorbing bed and the third primary adsorbing bed are communicated through a pipeline. The recovery rate of the organic waste gas purifying and recovering system for recovering an organic solvent waste gas is not less than 95 percent; the organic waste gas purifying and recovering system is good in recovering effect, is more environment-friendly and more energy-saving, and applicable to popularization.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment systems, in particular to an organic waste gas purification and recovery system. Background technique [0002] With the rapid development of my country's industrial and agricultural production, the use of organic solvents is also increasing. The daily use of organic solvents in some large factories is 3 to 4 tons; that of medium factories is 1 to 2 tons; and that of small factories is about several hundred kilograms. Factories that use organic solvents, such as container factories, copper clad laminate factories, plastic printing factories, furniture factories, chemical fiber factories, etc., are all over the country. [0003] There are carcinogens such as benzene, toluene, xylene, and chlorinated alkanes in the organic solvents used, whether they are volatilized indoors or outdoors, they will cause harm to humans, animals and plants. Under the action of sunlight, solvent gases such ...
