Dry quenching circulating diffused tail gas treatment device

Abstract

The invention discloses a dry quenching circulating diffused tail gas treatment device comprising a shell and a gas outlet disc, wherein a treatment tower is fixedly mounted in the shell; a water collecting tank is mounted at the lower end of the treatment tower; the left side of the water collecting tank communicates with a water inlet pipe of a water pump; a water outlet pipe of the water pump is fixedly connected with a three-way device, the upper end of the three-way device is fixedly connected with a connecting pipe, a first fan is mounted on the upper left side of the treatment tower, agas washing box is mounted on the lower side of the first fan, a recycling pipe is mounted on the lower left side of the gas washing box, and a filtering tower is fixedly mounted on the left side of the gas washing box. The dry quenching circulating diffused tail gas treatment device has the advantages that a liquid is sprayed out of an atomizing nozzle in a mist form through an upper spraying device and a lower spraying device, dust-containing tail gas can be cooled, particle impurities in tail gas are collected in the water collecting tank after being atomized, tail gas purification is morethorough, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment equipment, in particular to a dry quenching coke exhaust gas treatment device. Background technique [0002] As the environmental protection of the coking industry becomes more and more serious, the environmental protection standards are also getting higher and higher, regardless of water, gas, and dust must be controlled within the control range of national indicators; in response to industry trends, the company will treat the CDQ cycle release gas, The main idea is to remove the soot concentration in the circulating gas to ensure that the production of the ground station flue gas desulfurization system meets the national emission standards; the existing flue gas treatment device cannot reduce the temperature of the tail gas during treatment, so that after reaching the standard The exhaust gas temperature is high, which will have a certain impact on the atmosphere. In severe cases, it ...

[0002] As the environmental protection of the coking industry becomes more and more serious, the environmental protection standards are also getting higher and higher, regardless of water, gas, and dust must be controlled within the control range of national indicators; in response to industry trends, the company will treat the CDQ cycle release gas, The main idea is to remove the soot concentration in the circulating gas to ensure that the production of the ground station flue gas desulfurization system meets the national emission standards; the existing flue gas treatment device cannot reduce the temperature of the tail gas during treatment, so that after reaching the standard The exhaust gas temperature is high, which will have a certain impact on the atmosphere, and in severe cases, it will cause certain pollution to the environment. Therefore, it is urgent to produce exhaust gas purification treatment devices for chemical industry to solve the above problems
