Operation principle is described in detail below：
Mining wet precipitator water is passed through by feed pipe 14, and feed pipe 14 is divided into two towards impeller hub in exit
6 small outlet pipe, is not that the such water outlet bore of nozzle reduces or tortuous, so will not block because caliber is larger.Current along
Impeller hub 6 central lug position cambered surface and launch.Motor 4 be the two poles of the earth asynchronous machine, each second rotating speed close to 49 turns, by
In impeller hub in high-speed rotation, current are attached to rapidly on impeller hub 6, and get rid of into moisture film state by centrifugal force.Due to
The profile design of the contact current of impeller hub 6 is conducive to the shaping scattered with moisture film of current into circular shape.The dynamic of impeller is put down
During weighing apparatus adjustment, carried out in the opposite side of impeller hub 6.When being gradually increased with the radius that current leave the center of impeller hub 6, water
Film is also gradually thinning.Because rotating speed is very fast, so water-film-rate is more uniform, after moisture film leaves impeller hub 6, then become radiation
The moisture film and water smoke of shape, become " blockade line " for stopping dust in air-flow.
Air containing dust in tunnel, axial flow blower 2 is pumped into by wind collecting unit 1, after by impeller blade 7, dust-laden
Air-flow starts to contact moisture film and water smoke that impeller hub 6 throws away, and moisture film starts to be blown to be offset to airflow direction by air-flow to accelerate, and
Scatter.Water smoke is thrown into receipts water drum 8 under the double action of centrifugal force and air-flow along parabolical incline direction.Work as ash-laden gas
Flow during by the region that is made up of moisture film and water smoke, the dust in air-flow clashes into moisture film or water smoke, cohesion, and enter receive together
Water drum 8.The centrifugal force of the offer of impeller hub 6 is by means of due to moisture film and water smoke, the shock strength with dust is very fierce, therefore always
Efficiency of dust collection is higher.
Receive the inner chamber of water drum 8 and be dispersed with multi-disc block water plate 19, the Main Function of block water plate 19 is come when impeller hub 6 throws away
Water smoke enter receive water drum 8 when, can prevent, stop and buffered water aerosol bomb rise and splashes, next to that to receipts the structure of water drum 8 on
Strengthen.Block water plate 19 and water smoke contact position at first, are horn structure, to reduce the ejection of water smoke.The rear portion of block water plate 19 is then set
Annular water tank 20, to accommodate and collect water droplet.Because the block water plate 19 of whole ring-type is to erect direction to put, no matter above also
It is the water droplet of side, into after annular water tank 20, the front sewage disposal groove 15 of bottom will be flowed into, most flows out dedusting through blow-off pipe 25 afterwards
Device.The preceding orifice plate 24 covered on front sewage disposal groove 15, is isolated so that the pressure in dirt discharge groove 15 is slightly below to dirt discharge groove 15

Wheel wheel hub 6 throws away the tangential direction of water smoke, it is also possible to weaken the bounce-back and splashing of water smoke.
The afterbody for receiving water drum 8 is provided with common pressure chamber 26, and the bottom of common pressure chamber 26 communicates with inside front sewage disposal groove 15, so common pressure chamber
Less than the pressure near block water plate 19, the current and air-flow that the outer casing inner wall of water drum 8 is received to reaching have attraction to pressure inside 26
Effect.The air-flow in water drum 8 is received, due to the effect of impeller blade 7, really helical form is advanced.Hole on front apron 27
In the first half area of the rising for being distributed only over spiral air flow.This be due to spiral air flow decline halfth area when, its direction with collect
Current afterwards are same direction, and current are readily flowed into front sewage disposal groove 15.And in Ling Ban areas, current falling direction and spiral
Airflow direction is conversely, the current especially after top area, collection are very easily because gravity flows out again.Therefore in spiral air flow
Drilled on front apron 27 in the first half area of rising, the low pressure of common pressure chamber 26 is attracted current and air-flow.When current and air-flow
When reaching receipts 8 outer casing inner wall of water drum, take advantage of a situation and influenceed by the hypobaric of common pressure chamber 26, impinge upon on front apron 29, and fall into
Tank 29 afterwards, dirt discharge groove 16 after flowing into still further below.Some air-flows and current can enter common pressure chamber 26 from the hole of front apron 27, and
Row is flowed down with dust-containing water afterwards, into front sewage disposal groove 15.Can be mixed into dirt water into the gas in common pressure chamber 26, discharge deduster,
Escaped again in current, the gas of this part belongs to pure air.
The length for receiving water drum 8 determines that the wind speed with air-flow, the linear velocity of the outer rim of impeller hub 6 rotation is related, i.e., water smoke exists
Under the force action of centrifugal force and air-flow, the region of block water plate 19 is entered with parabolical track, main water smoke should fall into several groups
The centre position of block water plate 19, just can guarantee that most water smoke --- the sewage i.e. containing dust enters receives water drum 8.
Air-flow advances in the presence of draught fan impeller 7 in rotation, after by receiving water drum 8, can contain in air-flow
Mist.Further to make pneumatic dewatering, spy is provided with dehydration tube 11.Flow deflector 10 in dehydration tube 11 is the wind direction along air-flow
Set, the mist in air-flow can hit the dehydration on 9 surfaces of flow deflector 10, the inwall of dehydration tube 11 and diffusion cylinder under effect of inertia
On silk screen 34.Mist is bonded in the outside of silk screen 34 first, is flowed on wire mesh bottom along silk screen 34 after accumulation, then flows into rear dirt discharge groove
In 16, most deduster is flowed out through blow-off pipe 31 afterwards.The waterstop 35 of the taper type being welded on the afterbody flange of dehydration tube 11, can be with
Stop the water droplet outflow deduster after collecting, it is also possible to further stop and got rid of fog in eddy flow outer layer.After pneumatic dewatering, from
The rear shield 12 of deduster afterbody is discharged.Protection network on rear shield 12 is set primarily for security reason.
In coal mine roadway, dust-proof cistern can be set, the sewage of deduster discharge can be reclaimed into pond.Yin Benfa
