Device and method for treating waste gas with water

Abstract

The invention discloses a device and a method for treating waste gas by adopting water. The device comprises an atomizer, a charge loader, a mixer and a water scrubber, wherein a charge loader comprises a waste gas charge loader and a water mist charge loader; the waste gas charge loader comprises a waste gas pipeline, the waste gas pipeline is provided with a Venturi pipe section, and waste gas flows through the waste gas pipeline for charge loading; the water mist charge loader comprises a water mist pipeline, the water mist pipeline is also provided with a Venturi tube section, and the atomizer is connected with an inlet of the water mist pipeline to enable water mist to flow through the water mist pipeline for charge loading; the mixer is connected with an outlet of the water mist pipeline and an outlet of the waste gas pipeline so as to realize mixing of the waste gas and the water mist, and the water mist adsorbs the waste gas during mixing; and the water scrubber is connected with a mixing outlet of the mixer so as to treat the water mist having adsorbed waste gas through a water washing method. The device has the advantages that combustion explosion cannot be caused; the device is safe and reliable; and pollutants not soluble or hardly soluble in the waste gas can be effectively removed.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a device and method for treating waste gas with water. Background technique [0002] Organic waste gas and other waste gases are the main causes of air pollution. Waste gases can be divided into three categories: soluble in water, insoluble in water and difficult to dissolve in water. Waste gas soluble in water can be directly absorbed and removed by water spraying. Waste gas that is insoluble in water or insoluble in water cannot be removed by water spraying. Now, activated carbon adsorption, high-temperature combustion, catalytic combustion, zeolite runner combustion, photocatalysis, low-temperature plasma oxidation, ozone oxidation and other methods are used to remove them. Inseparable from storage (such as activated carbon adsorption method, the adsorption process is also the accumulation and storage process of flammable gases) or high temperature (such as c...

Problems solved by technology

Waste gas that is insoluble in water or insoluble in water cannot be removed by water spraying. Now, activated carbon adsorption, high-temperature combustion, catalytic combustion, zeolite runner combustion, photocatalysis, low-temperature plasma oxidation, ozone oxidation and other methods are used to remove them. Inseparable from storage (such as activated carbon adsorption method, the adsorption process is also the accumulation and storage process of flammable gases) or high temperature (such as combustion, catalytic combustion, zeolite runner combustion, etc.) or direct contact with high-voltage circuits (such as photocatalysis, low-temperature plasma) These methods are restricted by the ecological environment department and are not recommended due to the accumulation of combustible gas in the ignition pipeline, or the retention of combustible gas in the pipeline due to equipment failure, which will cause explosion hazards when ignited.
