Organic exhaust gas processing method and system thereof

Abstract

The present invention provides organic exhaust gas processing method and system thereof. Exhaust gas containing one or various organic solvent generates from production equipment, and first preprocessing by a exhaust gas preprocessing system (I) then entering a adsorption / desorption system (II) for adsorption and desorption, and the desorbed organic solvent entering a recovery system (III) for recycling, part of the desorbed organic solvent being used for production and the others entering a hypoxia hot air generation system (IV) for catalytic combustion to get hypoxia hot air, and using the obtained hypoxia hot air for desorption. Using the recycled organic solvent from the recovery system (III) as fuel to generate hypoxia hot air that making industries incapable of steam or inert gas supply being able to recovery organic solvent exhaust gas without secondary pollution, simultaneity resolving problem of system internal pollution caused by using variety fuels and equipment corrosion caused by steam.

Description

technical field [0001] The invention relates to the field of industrial organic waste gas treatment, in particular to a treatment method and system for organic waste gas, which are used in the production process of medicine, packaging, printing, light industry, coating, chemical industry, electronics, coating and other industries. The organic solvents in the generated waste gas are recovered and recycled. Background technique [0002] The waste gas generated in the production process of medicine, packaging, printing, light industry, coating, chemical industry, electronics, coating and other industries contains organic solvents, which not only causes the loss of raw materials, but also causes great pollution to the surrounding environment , while causing economic losses to production, it also produces certain harm to human health. These exhaust gases containing organic solvents can seriously damage the hematopoietic function of the human body. Many organic substances are car...

Problems solved by technology

[0005] In order to solve the problem that it is difficult for production enterprises without steam or inert gas generation conditions to desorb and recover organic solvents, the invention provides a treatment method for organic waste gas, which uses low-oxygen hot air to desorb and recover organic solvents, and the recovered organic solvents can be used in production At the same time, a part of the recovered organic solvent is used to generate low-oxygen hot air. This low-oxygen hot air desorption method provides production enterprises without steam or inert gas generation conditions to desorb and recover organic solvents without using steam or inert gas. method
