Specific embodiment
Dusty gas of the utility model by the way of ventilation and dust removal on degree getting working face is handled, and mainly has suction Gas, spray for dust suppression, dry three processes of water dumping.
The structure of the utility model is penetrated through, dedusting before and after dedusting cylinder 1 as shown in Figure 1, include the dedusting cylinder 1 of tubular The inlet end of cylinder 1 is equipped with the air amplifier 2 positioned at import section, and the rear portion of air amplifier 2 is spray atomizer 3, spray The rear portion of water atomizer(-iser) 3 is air deflector 4, and the rear half interior wall of dedusting cylinder 1 is equipped with dehydrator 5, after dehydrator 5 covers entirely Half interior wall.Air deflector 4 is that the flow deflector 401 of arc strip is arranged in a fixing axle of 1 center of dedusting cylinder, into Flow deflector 401 is pushed and is rotated by gas air-flow, and water mist and dusty gas are got rid of dehydrator 5 posteriorly by the rotation of flow deflector 401;Dehydration Device 5 is the permeable plastic plate of flexible mesh, is drainage flow chamber between dehydrator 5 and dedusting cylinder 1, dedusting cylinder 1 is in sewage stream Dynamic bottom of chamber portion is equipped with mudhole 6.
In the utility model air amplifier 2 be 8 groups and by air hose 201 it is radial collect be connected to blast pipe 202, into Air hose 202 is introduced from 1 side wall of dedusting cylinder, and the length of air hose 201 and alternate angle are identical, and the position that air hose 201 collects is in The center of dedusting cylinder 1, as shown in Figure 3.
Air amplifier 2 is metal structure, as shown in Fig. 2, being divided into the outlet air end of front flaring air intake 203 and tubular 204, the reaming of the centre bore and air intake 203 of outlet air end 204 is air duct, and outlet air end 204 is set in the barrel of air intake 203 There is the annular housing 205 of circular 204 cylinder of outlet air end, annular housing 205 extends and be connected to flaring at the rear portion of flaring to be formed Annulus 206, forms curved wall 207 between 203 inner wall of annulus 206 and air intake, and annular housing 205 passes through outlet air end 204 Inner wall formed air inlet 208 be connected with air hose 201, air intake 203 of the flaring of air intake 203 towards dedusting cylinder 1, outlet air The centerline parallel at end 204 is in the center line of dedusting cylinder 1.
Air amplifier 2 is to enter annular housing, high pressure gas warp by air inlet using high pressure gas as power source Annulus ejection is crossed, gas is sprayed and is flowed along curved wall, and generates 90 ° of steerings, final gas is attracted to outlet air end It is flowed on inner wall, generates a negative pressuren zone in the center of air intake, this negative pressure can be air in air intake flaring position Air sucking outlet air end all living creatures heart hole in, the wind of sucking can and original high pressure draught converge, this strand of new high-speed flow from Outlet air end end sprays.The air expansion that air amplifier 2 sucks, speed increase, pass through together with the compressed air of supply Heart hole.When air amplifier outlet does not connect conduit, the air-flow to gush out from centre bore can also bring the air around more into. Final outlet tolerance (air of sucking+compressed air of the supply+air brought into) and the ratio of entrance air demand can achieve 40: 1.Theoretical calculation is carried out to air amplifier, obtaining determining air inlet is diameter 15mm, annular gap 3mm, and centre bore is straight Diameter is 78mm, and the utility model just uses almag as the air amplifier of material processing and fabricating.
The air amplification factor relation table of single air amplifier
For the amplification factor of air amplifier substantially at 38 times or so, single air amplifier can not as can be seen from the above table Meet dedusting fan needs.Select eight air amplifiers as an assembly by calculating, the air inlet of air amplification is logical It crosses air hose to be evenly distributed on a disk, internal diameter 700mm, outer diameter 800mm, intermediate disc is pressed gas shunting Device guarantees that each air amplifier air demand is uniform, and intermediate disc connects air inlet, and air inlet connects high-pressure air source.
Spray atomizer 3 be multiple atomizers 301 by water pipe 302 it is radial collect be connected to water inlet pipe 303, intake Pipe 303 is introduced from 1 side wall of dedusting cylinder, and the length of water pipe 302 and alternate angle are identical, and the position that water pipe 302 collects is in and removes The center of dirt barrel body 1;The water mist direction that atomizer 301 sprays is to the rear portion of dedusting cylinder 1, as shown in Figure 4.
Flow deflector 401 is two groups of arc-like sheets, and curvature 180mm, one end is fixed in a shaft with slightly angled manner, is inclined Tilted direction is flow deflector rotation direction
Shaft is arranged on bearing, the inner wall that bearing is fixed on dedusting cylinder by connecting rod structure.
It is viscid due to pressure-air working principle of the utility model is: pressure-air enters air amplifier by pipeline Effect, forms powerful negative pressuren zone in entrance, and high pressure water is atomized by spray atomizer, and air is viscid near nozzle Effect forms negative pressuren zone at atomizer rear, and two negative pressuren zones form more powerful negative pressure by superposition.The distinguished and admirable quilt of dust-laden Above-mentioned negative pressure sucks dedusting cylinder, and the high speed of air amplifier is distinguished and admirable after sucking dust-laden is distinguished and admirable will sufficiently hit atomization with water mist and mix It closes, after dust-laden waste air is inhaled into dedusting fan, the water mist and dust sprayed by spray atomizer generates collision, by water mist to powder The trapping that dirt generates acts on forming dirt aqueous mixtures, and by the effect of distinguished and admirable guider, air-flow becomes helical form, dust-contained airflow quilt Dehydrator is thrown to, the dirt aqueous mixtures of waste air are sloughed under the action of dehydrator, sewage is flowed out from mudhole.It is a series of by this Effect, clean gas is flowed out in the end of final dedusting fan.
Present apparatus overall mass is 120Kg, and for the dedusting fan with model generally all in 350Kg or more, present apparatus quality is remote It is lighter than the latter.Noise test is carried out to this dedusting fan, noise < 65dB when maximum suction air volume, and common dedusting fan noise Up to > 85dB, in addition the present apparatus is non-electric fan, and general dedusting fan needs to use motor impeller fan, comprehensive Pick work increase is very dangerous with electric line, and the negative pressure that the generation of combination type air amplifier is utilized in the present apparatus makes dust-contained airflow It is inhaled into blower, it is only necessary to supply a small amount of high pressure gas, high pressure gas comes from mine air above compressor, defeated by pipeline Send all fully mechanized workface present apparatus relative to common dedusting fan not only safety coefficient height, but also light weight convenient transportation peace Dress, it is not necessary to which electricity consumption, reduces energy consumption.
