A wet-type dust-collecting air flow cooling device

Abstract

The invention provides a wet-type dust-capturing wind current cooling device mounted at a head-on rear position of a mining working face mining machine, connected with an outlet end of a polluted wind pumping canister and comprising a cover shell, and a spray dedusting device, a cyclone centrifugal dedusting device, a dust screen filtering device, an air cooling type heat exchanger and a baffle plate demister which are connected in order inside the cover shell; positions of the cover shell walls below the cyclone centrifugal dedusting device and the baffle plate demister are respectively provided with drainage pipe ports. Fully-mechanized excavating working face dust capturing and wind current cooling works are combined together, with a treatment mode of firstly dust capturing and then wind current cooling, polluted wind is firstly subjected to multi-stage dust capturing treatment and then is demisted and cooled, the working face wind current temperature is controlled in a suitable temperature, a safe and comfortable working environment of the down-hole working face is ensured, and the problems of high temperature and high dust of the mine mining working face are better solved.

Description

technical field [0001] The invention relates to an air flow cooler, in particular to a wet dust collecting air flow cooling device, which belongs to the field of mine dust removal and temperature reduction. Background technique [0002] At present, coal still occupies a dominant position in my country's energy structure. With the continuous increase of coal mining depth, the continuous improvement of the degree of mechanized mining, and the continuous increase of the installed capacity of the working face, the dust production of the fully mechanized excavation working face has increased and high temperature problems have emerged one after another, seriously affecting the safe production of mines and the health of employees. . [0003] A large number of studies and tests at home and abroad have proved that: in the complex working environment of fully mechanized excavation working faces, the problems of high dust concentration and high temperature in the air flow are particul...

AI Technical Summary

Problems solved by technology

[0006] However, at the present stage, the dust control and dust removal system and the cooling regulation system of the high-temperature dust-producing working face in my country work independently and independently, resulting in a large work space and a serious lack of economic rationality
