The waste gas treating system comprises a spray chamber, a settling water-storage tank and a dewatering tower, wherein a smog passage is formed in the spray chamber; a smog inlet and a smog outlet are respectively formed in the front end and the rear end of the smog passage; more than one row of spray nozzles are arranged along the smog passage; a water outlet is formed in the bottom of the smog passage; the smog inlet is communicated with the damp outlets of a tobacco leave redryer and a tobacco stem redryer through pipelines; the smog outlet is communicated with a gas inlet of the dewatering tower through a pipeline; the settling water-storage tank is provided with a water pump; a water inlet of the water pump is communicated with a spray liquid in the settling water-storage tank; a water outlet of the water pump is communicated with the spray nozzles through pipelines; a reflux hole is formed in the bottom of the settling water-storage tank; the reflux hole is communicated with the water outlet of the smog passage through a pipeline; multiple adsorption layers are arranged between the gas inlet and a gas outlet in the dewatering tower; the gas outlet of the dewatering tower is communicated with an external boiler chimney through a fan.

The invention relates to the waste gas treating field of electroplating industry, in particular to a waste gas treating system. The waste gas treating system comprises a gas scrubbing tower. The front end of the gas scrubbing tower is provided with a cyclone separating tower, an air inlet part of which is provided with a plurality of gas inlet pipelines, and each gas inlet pipeline is respectively provided with a suction fan and an air suction cover. By taking the air inlet part of the cyclone separating tower as a connecting part, the gas inlet pipelines are counterclockwise arranged in the circumferential tangential direction of the air inlet pipeline. The gas inlet pipeline is respectively provided with a check baffle plate. At least one gas inlet pipeline at the front end of the cyclone separating tower is provided with equipment for pretreating special waste gas. The cyclone separating tower is provided with a cooling device. The system is provided with switches for flexibly adjusting the suction fans according to the treating requirement, therefore, the operation cost can be controlled, and the waste gas of different sources and properties can be flexibly treated; the gas inlet temperature of the gas scrubbing tower is decreased, the Reynolds number is increased, the acid removing effect of the gas scrubbing tower is enhanced, the usable waste acid can be recycled, and the resources are sufficiently saved.

A liquid aminoether acid gas absorbent which is subject to freezing in a cold climatic zone though which the aminoether is to be shipped is rendered freeze-resistant by mixing the aminoether with water prior to transport through the cold climatic zone; the aminoether / water mixture typically contains 10 to 40 weight percent water, based on the weight of the aminoether. The aminoether / water mixture can also be stored in the cold climatic zone without being externally maintained at a temperature above the inherent freezing point of the aminoether.
