Description

A kind of colliery Wet-type dust-removal fan demister
Technical field
The utility model relates to the demister of a kind of colliery Wet-type dust-removal fan.
Background technique
Along with improving constantly of the mine machinery level of production, mine dust-producing amount sharply increases, the serious threat safety in production of mine and the healthy of worker.Large quantifier elimination and test both at home and abroad proves: utilizing and taking out dirt purification is solve one of the most effective technological approaches of channel of coal mining working surface dust pollution question.The key equipment taking out dirt purification technics is dedusting fan, and the dedusting fan for underground coal mine must ensure higher dust removal efficiency and larger process air quantity, ensures normal working environment at coal mines simultaneously.But, existing Wet-type dust-removal fan in dedusting working procedure, due to the restriction of himself design condition, distinguished and admirable humidity restriction requirement can not be ensured after dedusting, often there is a large amount of droplet to get rid of with fan outlet, have a strong impact on underground work environment, even can bring out security incident.Therefore, while the dust removal efficiency of making great efforts to be up to state standards and process air quantity, for avoiding processing the larger result of rear distinguished and admirable fog, ensureing underground work environment, being badly in need of designing the colliery Wet-type dust-removal fan demister that effectively can process fog droplet.
Model utility content
For the problem that distinguished and admirable fog after the Wet-type dust-removal fan dedusting of existing colliery is larger, the utility model proposes a kind of colliery Wet-type dust-removal fan demister.
The utility model adopts following technological scheme:
A kind of colliery Wet-type dust-removal fan demister, comprise dedusting fan air duct, be provided with motor and spraying device in described dedusting fan air duct, described spraying device comprises blower fan water pipe, described blower fan water pipe connects nozzle support pipe, and described nozzle support pipe is provided with several atomizer nozzles, described spraying device connects atomising device at dedusting fan air duct entering-dust mouth place by water pipe, described atomising device comprises intake pipe, described intake pipe is provided with switching ball, water storage box is connected bottom intake pipe, described water storage box connects water filter by water pipe, described water filter connects electric booster pump by water pipe, described electric booster pump accesses the spraying device in described dedusting fan air duct by water pipe, described dedusting fan air duct is connected with a demister at exhaust port place, several baffling blades are provided with in described demister, described several baffling blades heap is connected together.
Preferably, described baffling blade is provided with 2 ~ 5 dogleg passage, in obtuse angle, this obtuse angle is between 90 ° ~ 120 °, and the spacing of adjacent baffling blade is 30mm ~ 40mm in the cross section of dogleg passage.
Preferably, described baffling blade surface is provided with dust removel fiber layer.
The beneficial effect that the utility model has is:
The colliery Wet-type dust-removal fan demister that the utility model provides, to Wet-type dust-removal fan with the use of demister, tackles a large amount of dust and the droplet of distinguished and admirable middle generation.Because mostly concentrating near blower fan barrel containing nebelwind stream, pie structure narrow-minded in wide around the demister form structure of design, reduces materials application, reaches except fog effect.
Dust-laden is distinguished and admirable can there is vortex motion through demister, there is local eddy currents phenomenon, increase the touch opportunity that dust-laden contains nebelwind stream and baffling blade, the passage of many sub-threads is separated into after entering blower fan demister, under the effect of inertial force, the collision of drop mist forms liquid film on waveform plate, the dust removel fiber of baffling blade surface makes liquid film adhesion droplet effect more remarkable, fog moves forward to air-flow that turning is separated gets off, discharged by drain opening, dirt aqueous mixtures is removed.Dust removel fiber has larger coefficient of frictional resistance, and roughness reaches 0.60, can effectively trap the droplet in distinguished and admirable, and meanwhile, demister has carried out again removing to dust, improves the dust-laying effect of Wet-type dust-removal fan.
While having ensured dedusting fan dust removal requirement, greatly reduce the humidity that air-out is distinguished and admirable, distinguished and admirable dustless without mist after process, ensure mine working environment.After measured, the demister that the utility model provides, maximum choke amount is only more than 5%, demisting efficiency has exceeded 90%, effectively reduces mine Wet-type dust-removal fan droplet concentration, also can intercept the dust of distinguished and admirable middle droplet parcel simultaneously, increase dust removal efficiency, ensure mine working environment.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Composition graphs 1, Fig. 2 and Fig. 3, a kind of colliery Wet-type dust-removal fan demister, adopts Mechanics of Machinery filtered version to catch the theory of dust and droplet, to Wet-type dust-removal fan with the use of demister, tackles a large amount of dust and the droplet of distinguished and admirable middle generation.A kind of colliery Wet-type dust-removal fan demister, comprise dedusting fan air duct 7, motor and spraying device is provided with in described dedusting fan air duct 7, described spraying device comprises blower fan water pipe 6, described blower fan water pipe 6 connects nozzle support pipe, and described nozzle support pipe is provided with several atomizer nozzles; Described spraying device connects atomising device at dedusting fan air duct 7 entering-dust mouth place by water pipe, described atomising device comprises intake pipe 1, described intake pipe 1 is provided with switching ball 2, water storage box 3 is connected bottom intake pipe, described water storage box 3 connects water filter 4 by water pipe, described water filter 4 connects electric booster pump 5 by water pipe, and described electric booster pump 5 accesses the spraying device in described dedusting fan air duct 7 by water pipe.Described dedusting fan air duct 7 is connected with a demister 8 at exhaust port place, is provided with drain opening 9 bottom described demister 8, is provided with several baffling blades 10 in demister 8, and several baffling blade 10 heaps described are connected together.Each baffling blade is provided with 2 ~ 5 dogleg passage, and in obtuse angle, this obtuse angle is between 90 ° ~ 120 °, and the spacing of adjacent baffling blade is 30mm ~ 40mm in the cross section of dogleg passage.Baffling blade surface is provided with dust removel fiber layer, and dust removel fiber has larger coefficient of frictional resistance, and roughness can reach 0.60.
