Abstract
The utility model relates to a mining dust removing device, in particular to a mining wet dust removing device, comprising a exhaust contra-rotary fan, a dust removing box, a slide and an air regulator, wherein a negative pressure ventilation pipe is mounted at one end of the exhaust contra-rotary fan, and another end is connected with the inlet of the smoke at the end side of the dust removing box through a positive pressure ventilation pipe; an air guiding plates assembly and a dehydrator are mounted in the dust removing box; air guiding plates assembly and the dehydrator form a curved channel from the smoke inlet to the dehydrator; the top of channel is open-type and is immersed in the water in the box; and the air regulator is mounted outside of the smoke outlet of the another side of the dust removing box. The dust removing device has three dust removing functions with using water flow, drop and film separately and the total dust removing ratio is 90% and has the advantages of explosion proof, electric spark proof, good safety performance, small volume, light weight, simple operation, low water consumption and low production cost. Therefore the utility model is suitable for ventilation and dust removing on mechanical mining area underground.
Description
Technical field:
The utility model relates to the mine dust removing device of the development works face dedusting of the tunneling working face dedusting of down-hole, mine or dirt source concentrating, particularly a kind of mining wet dust removal device.
Background technology:
Dust is one of down-hole, mine idea disaster, and wherein the dirt source of tunneling working face is maximum, and dust concentration is up to 1000-3000mg/m
3, and the decentralization height, wherein particle diameter accounts for more than 85% less than the respirable dust of 7 μ m, if adopt general measurements for reduction, is difficult to remove these respirable dusts.Though known shaped Venturi dedusting device, bag type filtering dust arrester, self-excitation wet dust removal device and electrostatic precipitator etc. are removed less than the respirable dust effect of 7 μ m and still can, but the cost that these dust arresters have is expensive, the big flow of the resistance that has is little, the big Heavy Weight of the volume that has, thereby all can not be applied directly to the down-hole, mine.For a long time, the mine generally adopts spraying to spread the water dust suppression, and test showing that spraying spreads water the efficiency of dust collection of respirable dust only is 30-50%, energy consumption height.
Summary of the invention:
Goal of the invention of the present utility model is intended to solve that concentrate in the dirt source and the dust removal problem of the work plane that dust concentration is high, and a kind of volume is little, in light weight, cost is low, water consumption is little, move efficient mining wet dust removal device easy for installation and provide.
The technical scheme that realizes the foregoing invention purpose is: this is mining, and the wet dust removal device comprises the pull-out type counter-rotating fan, the dust cleaning case casing, skid, parts such as air register, this pull-out type counter-rotating fan one end is equipped with the negative pressure air duct, the other end links to each other by the distolateral flue dust import of malleation air duct and dust cleaning case casing, in this dust cleaning case casing guide plate assembly and dehydrator are housed, this guide plate assembly and boxboard constitute from the flue dust import bending channel to dehydrator, the curved top of this bending channel is open shape and is immersed in the interior pond of casing, and air register is equipped with in the exhanst gas outlet outer end of this another side of dust cleaning case casing.
According to described this mining wet dust removal device of this case, its dust removal process is: dusty gas is under the effect of pull-out type counter-rotating fan, be pressed into dust cleaning case by negative pressure air duct and malleation air duct, flue dust impacts the water surface along the passage that the downward guide vane of turning constitutes, bigger grit is because the coherence effect falls into the pond, and less grit during by the bending channel between last guide vane, fully collides and the sedimentation that is hunted down with a large amount of water droplets that evoke with higher speed with air-flow.The moisture air-flow of dust-laden under action of centrifugal force, forms certain thickness moisture film again on dust cleaning case inwall and guide vane, grit is captured descend.After removing water droplet and water smoke in the air-flow by dehydrator again, be discharged in the tunnel by air register.
Compared with prior art, this dust arrester is owing to have three kinds of dedusting functions of moisture film of water-bath, water droplet, centrifugal force generation, thereby can obtain higher dust removing effects, its total dust removal efficiency is up to 98%, the respirable dust efficiency of dust collection is up to 90%, and have explosion-proof, no electric spark, security performance is good, volume is little, in light weight, simple to operate, advantage, the dust control by ventilation of suitable especially mine down-hole mechanical driving face such as water consumption is low, cost is low.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Provide the specific embodiment of this case below in conjunction with accompanying drawing.
The mining wet dust removal device that present embodiment provides is by negative pressure air duct 1, pull-out type counter-rotating fan 2, malleation air duct 3, flue dust import 4, dust cleaning case casing 5, guide plate assembly 6, dehydrator 7, exhanst gas outlet 8, air register 9, sewage draining exit 10, skid 11, guide vane 12 parts such as grade are formed, these pull-out type counter-rotating fan 2 one ends are connected with negative pressure air duct 1 by clip, the other end is connected with malleation air duct 3 one ends by clip, these malleation air duct 3 other ends are connected by the 5 distolateral flue dust imports 4 of clip and dust cleaning case casing, guide plate assembly 6 and dehydrator 7 are housed in this dust cleaning case casing 5, this guide plate assembly 6 and boxboard welding, formation is the bending channel to dehydrator 7 from flue dust import 4, the curved top of this bending channel is open shape and is immersed in the pond in the casing 5, air register 9 is equipped with in exhanst gas outlet 8 outer ends of these dust cleaning case casing 5 another sides, and its pond bottom side is provided with sewage draining exit 10.
Negative pressure air duct 1 concentrates the position to collect mine dust from the dirt source, pull-out type counter-rotating fan 2 sucks the mine dust of collecting and is imported in the dust cleaning case casing 5 by malleation air duct 3, the dedusting mechanism of being made up of the pond of guide plate assembly 6, dehydrator 7 and casing 5 bottoms in the casing 5 is finished the dedusting dehydration again, and flue gas after being purified is discharged by exhanst gas outlet 8.Air register 9 is by regulating the working resistance that air quantity is regulated dedusting mechanism.
These pull-out type counter-rotating fan 2 bottoms and dust cleaning case casing 5 bottoms in the present embodiment are equipped with skid 11 respectively, and it mainly acts on is to be used for guiding and to be convenient to transportation.
