FIELD: waste gas treatment.
SUBSTANCE: group of inventions is a system for cleaning waste gases with the possibility of effective cleaning of waste gases formed during a variety of working processes. A centralized and autonomous system for cleaning waste gases and a method for cleaning waste gases of many working processes are claimed. Waste gases generated by a variety of work processes pass through pipes to transport the waste gases to a treatment system containing an integrated column. The integrated column consists of multiple self-contained units or sets of activated carbon adsorption units. The cleaning system also includes a desorption column, where the waste gas generated during each working process is cleaned in a stand-alone unit or a set of activated carbon adsorption units. The activated carbon adsorbed by the contaminant in the activated carbon adsorption unit or set is desorbed and reconstituted in the desorption column and then sent to each activated carbon adsorption unit or set for circulation. In the cleaning system according to the present invention, the waste gas generated during each working process is cleaned separately, the waste gas flow generated during each working process is not interfered with, different emission standards and different operating parameters are provided for cleaning the waste gas generated during each working process. And then the activated carbon is desorbed centrally. Thus, the use of the desorption column is significantly reduced, equipment costs are saved, and at the same time, the utilization rate and production efficiency of the desorption column are improved.
EFFECT: group of inventions makes it possible to effectively purify the waste gases formed during a variety of processes.
