Description
Technical field
The utility model belongs to organic gas and reclaims field, is specifically related to a kind of new and effective recovery system for organic solvent.
Background technology
The waste gas containing organic solvent that industrial production discharge is a large amount of, such as, the production processes such as printing, leather are produced, spray paint all give off a large amount of waste gas containing organic solvent.Country because the organic solvent be discharged in air photochemical reaction can occur under irradiation by sunlight, produces the material that environment and human body are harmful to, so will progressively take mandatory law clause to strengthen the improvement of the waste gas containing organic solvent.
The effective ways that organic solvent is purifying exhaust air are reclaimed from containing the waste gas of organic solvent; people utilize the process of molecular sieve concentration runner containing the waste gas of high boiling organic solvent usually, and process comprises adsorbent water vapour desorption containing the method that the waste gas of low boiling point organic solvent is conventional or adsorbent nitrogen protection adds thermal desorption and UF membrane recovery etc.
