Pipeline dust-settling device for chemical exhaust treatment

Abstract

The invention discloses a pipeline dust-settling device for chemical exhaust treatment, comprising a front joint, a dust-settling pipe and a back joint. The back joint is provided with a front end cover connected with an air cylinder, an output rod of the air cylinder is provided with a telescopic rod which penetrates the back joint to be further hinged to a hinge rod, the hinge rod is fixedly connected with a dust scraper, a sleeve which is integrally molded with the dust scraper is arranged on the top of the dust scraper, a drive shaft penetrates the dust-settling pipe, one end of the driveshaft is fixedly connected with an output shaft of a stepping motor, two circular discs are fixedly connected with the drive shaft, a vane impeller is fixedly connected between the two circular disc,and a spray pipe is fixedly connected onto the top of the dust-settling pipe while a dust-collecting pipe is fixedly connected onto the bottom of the dust-settling pipe. The dust-settling pipe is mounted by means of flange connection in an exhaust pipeline, exhaust flow drives the vane impeller to rotate so that the vane impeller touches dust repeatedly to attach the same, and thus, dust settlingeffect is realized effectively. The pipeline dust-settling device is simple in structure, easy to operate and worthy of population.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment, in particular to a pipeline dust suppression device for chemical tail gas treatment. Background technique [0002] Chemical waste gas refers to the poisonous and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health. The composition of chemical waste gas produced by different chemical production industries varies greatly. According to the form of pollutants, chemical waste gas can be divided into particulate pollutants and gaseous pollutants. Particle pollutants include dust particles, dust, smoke, fog, coal dust, etc. ; Gaseous pollutants include sulfur-containing compounds, chlorine-containing compounds, carbon oxides, hydrocarbons, halogen-oxygen compounds, etc. [0003] The par...

AI Technical Summary

Problems solved by technology

[0003] The particle size of particulate pollutants is relatively large, and their physical and chemical properties are quite different from those of gaseous pollutants. In the prior art, particulate pollutants and gaseous pollutants are generally treated separately to reduce the difficulty of comprehensive treatment. For this reason, a kind of A pipeline dust suppression device that effectively reduces dust in exhaust gas has become a problem that those skilled in the art need to solve urgently
