Abstract
The invention relates to an air purification method of a mine centrifugal dust-removing fan system. The largest problem in the mining of mines is as follows: the excavation operation is carried out under the mines, and during excavation operation, a great quantity of dust and harmful gas are generated to pollute the working environment and damage the body health of workers. The mine centrifugal dust-removing fan system comprises a dust-removing fan (1), wherein the dust-removing fan is arranged on a fan supporting frame (2), the fan supporting frame is arranged on a matching trolley (3), the two ends of the dust-removing fan are respectively connected with a positive wind pressure drum (4) and a negative wind pressure drum (5), and the positive wind pressure drum and the negative wind pressure drum are respectively arranged on a wind drum frame (6); the dust-removing fan comprises a mixing room, a fan is arranged in the mixing room, the mixing room is connected with a purifying room and the purifying room is communicated with a dehydrating device; the fan is directly provided with a group of vanes. The air purification method of the mine centrifugal dust-removing fan system, which is disclosed by the invention, is applied to mining equipment of the mines.
Description
technical field:
the present invention relates to a kind of air purification method of mining centrifugal dedusting fan system.
background technology:
the greatest problem that pit mining faces is excavated exactly under mine, during excavation, can produce many dust and pernicious gas, severe contamination working environment; Endangered the healthy of worker.
summary of the invention:
the air purification method that the purpose of this invention is to provide a kind of mining centrifugal dedusting fan system.
above-mentioned purpose realizes by following technical scheme:
a kind of mining centrifugal dedusting fan system, its composition comprises: dedusting fan, described dedusting fan is arranged on the blower fan bracing frame, described blower fan bracing frame is arranged on supporting dolly, described dedusting fan two ends connect respectively righteous style and practice pressure cylinder and negative wind pressure cylinder, and described righteous style and practice pressure cylinder and negative wind pressure cylinder are arranged on respectively on the air duct frame; Described dedusting fan comprises mixing chamber, described mixing indoor location blower fan, and described hybrid connection clean room, described clean room is communicated with dewater unit; Described blower fan is directly installed one group of impeller.
the air purification method of described mining centrifugal dedusting fan system, in described mixing chamber, described blower fan fully mixes dusty gas with the humidification spray water, the dust granules of various particle diameters forms oarse-grained mud pellet after by moisture absorption high velocity impact, with the tangential velocity of setting, enters described clean room; In described clean room, the gas of eddy flow Density Separation device high speed rotation, water, mud three-phase mist in centrifugal force field according to particle diameter and density stratification, mud pellet, the oarse-grained globule accelerate near and are adsorbed onto on barrel to discharge, cleaned air with droplet is being discharged after aqueous vapor is separated again, thereby reaches air purification effect.
the air purification method of described mining centrifugal dedusting fan system, in described mixing chamber, the air-flow produced after described impeller, corkscrew while moving and be the conulite shape along the inwall of body fuselage at air-flow, the air-flow of core can flow to border, utilizes the mixed dust of its powerful centrifugal force separate dusty gas and humidification spray water.
beneficial effect:
1. the dedusting fan that the inventive method relates to mainly is comprised of mixing chamber, clean room, blower fan, dewater unit four parts, its structural member all forms with Plate Welding, each section air duct connected by flange plate bolt, adopt impeller and motor associated mode, the compact conformation of whole device, sturdy and durable, use safety, easy to maintenance, be convenient in mobile environment, use under mine.Can change supporting leg into support, facilitate client's Mobile fan.This device can also increase reducing cylinder before mixing chamber, meets the demand of different mineral.Dedusting fan is arranged on the blower fan bracing frame, adds dolly again below the blower fan bracing frame, convenient mobile.
2. in the mixing chamber of the inventive method, be Wet-type dust-removal fan, this dedusting fan has concurrently and ventilates and the dedusting dual-use function, mainly being applicable to the more concentrated product dirt setting dust laden air of colliery downhole powder dust purifies on the spot, and can partly eliminate the poisonous and harmful element in gas, effectively make operating environment meet the industrial hygiene standard, guarantee miner's healthy and mine safety production.
3. the dedusting function of the inventive method is determined by the technical characterictic of self fully, do not need additional complicated dedusting filter, solved existing like product use at the scene in filter screen very easily stop up, filter screen one stops up, efficiency of dust collection obviously descends, even lose this puzzlement of use value technical barrier for many years, reach and reduce dust pelletizing system resistance, raising efficiency of dust collection, more can meet on-the-spot needs.
