Waste gas treatment equipment for industrial environmental protection

Abstract

The invention discloses waste gas treatment equipment for industrial environmental protection. The equipment comprises a settling tower, a hot drying chamber, a dust removal chamber and an activated carbon adsorption tower which are sequentially connected through pipelines. An air inlet is formed in the lower portion of the settling tower, the top of the settling tower is connected with the hot drying chamber through a pipeline, an air extracting pump is installed on the pipeline between the hot drying chamber and the dust removal chamber, a filter screen is installed in the pipeline between the dust removal chamber and the activated carbon adsorption tower, and a dustproof assembly is installed in the dust removal chamber. According to the invention, dust or smoke dust in the waste gas isfully removed through the combined action of pre-sedimentation, hot-drying water removal and multi-stage dust blocking, so that a good purification effect of the subsequent waste gas is ensured.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas purification, in particular to waste gas treatment equipment for industrial environmental protection. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during the fuel combustion and production processes in the factory area. Industrial waste gas will cause serious harm and impact to the environment and human body, so it is necessary to use purification equipment. Harmful substances in the exhaust gas are fully purified and filtered. [0003] Most of the existing waste gas treatment equipment or systems use catalytic oxidation, spray absorption or active adsorption. In the whole process of waste gas treatment, dust must be fully removed first to ensure a good subsequent purification effect, especially for In the way of active adsorption, when the dust content in the exhaust gas is large and a...

Problems solved by technology

[0003] Most of the existing waste gas treatment equipment or systems use catalytic oxidation, spray absorption or active adsorption. In the whole process of waste gas treatment, dust must be fully removed first to ensure a good subsequent purification effect, especially for In the way of active adsorption, when the dust content in the exhaust gas is large and accompanied by water vapor, the adsorption effect of the entire activated carbon adsorption layer will be greatly reduced, and the dust accompanied by water vapor will block the pores on the surface of the activated carbon, thereby reducing the service life of the activated carbon.
