The dusty water is filtered by two stages of screens, which ensures the cleanliness of the working water. The high pressure water mist wet type dust remover avoids the mine gas accidents owing to that no electric spark and friction spark is created in the ventilating duct.
Description
Technical field
The utility model relates to a kind of wet dust removal machine, is specially high-pressure water mist wet dust removal machine.
Background technology
Existing wet dust removal machine structure comprises: the ventilation duct that has air inlet and gas outlet, place the water mist dust fall device at ventilation duct air inlet place, separated by a distance with the water mist dust fall device, be installed in the screen pack on the ventilation duct, the water tank of screen pack is equipped with in inside, the water pump that one end is connected with water tank, the other end is connected with the water mist dust fall device, the return pipe that places the ventilation duct bottom and be communicated with water tank is plugged in the water inlet pipe in the water tank; The gas outlet is equipped with air exhauster; The problem that the wet dust removal machine of this structure exists is: the dust in (1) current failed to remove before reflow tank in advance, caused dust-laden current reflow tank; (2) though screen pack is housed in the water tank, dust deposit is in water tank, and the water that can't guarantee to enter water pump effectively is clean water; (3) the wet dust removal machine of this structure, because current the time are closed circulation in work, and when in subway, mine and other tunnel, using dust removal machine, all be to make its continuous uninterrupted work, so, can't realize being deposited on the effect that the dust in the water tank is in time removed from water tank.
Summary of the invention
The utility model provides a kind of high-pressure water mist wet dust removal machine at the problems referred to above that existing wet dust removal machine exists.
The technical solution of the utility model realizes by following structure: a kind of high-pressure water mist wet dust removal machine, its structure comprises: the ventilation duct that has air inlet and gas outlet, place the water mist dust fall device at ventilation duct air inlet place, separated by a distance with the water mist dust fall device, be installed in the screen pack on the ventilation duct, the water tank of screen pack is equipped with in inside, the water pump that one end is connected with water tank, the other end is connected with the water mist dust fall device, the return pipe that places the ventilation duct bottom and be communicated with water tank is plugged in the water inlet pipe in the water tank; The ventilation duct bottom has the filtration mouth of band water storage tank, and screen pack is installed in and filters on the mouth; The water mist dust fall device is the high-pressure nozzle of a nozzle towards the gas outlet; The ventilation duct bottom at place, gas outlet has the mud hole of band slag blocking plate; Water pump is a high-pressure hydraulic pump; Return pipe is communicated with the water storage tank bottom; The external water source of water inlet pipe.During work, because high-pressure nozzle ejection high-pressure water mist makes the air inlet place form the air negative pressure district, in dust laden air suction ventilation pipe, dust with after water liquid mixes, is deposited on the ventilation duct bottom in stroke, filter by filtering mouthful dust that major part is mixed with water liquid, discharge by mud hole.
The utility model is reasonable in design, because high-pressure hydraulic pump outlet hydraulic pressure can reach the 40-120 kilogram, so dedusting air quantity scope is big, according to instructions for use, can reach 100-650m
3/ min, ventilation duct length can reach about 300 meters, can satisfy the actual needs in subway, mine and other tunnel; Dust infiltration rate is up to more than 95%, so good dedusting effect; The dust-laden current adopt the two-stage strainer filtering, have guaranteed the cleannes of working water; Because no electric spark and friction spark have been avoided the generation of mine gas accident, so the utility model is particularly suitable for the dedusting needs of gaseous mine in the ventilation duct.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
A kind of high-pressure water mist wet dust removal machine, its structure comprises: the ventilation duct 3 that has air inlet 1 and gas outlet 2, place the water mist dust fall device 4 at ventilation duct air inlet place, separated by a distance with the water mist dust fall device, be installed in the screen pack 5 on the ventilation duct, the water tank 6 of screen pack is equipped with in inside, the water pump 7 that one end is connected with water tank, the other end is connected with the water mist dust fall device, the return pipe 8 that places the ventilation duct bottom and be communicated with water tank is plugged in the water inlet pipe 9 in the water tank; The ventilation duct bottom has the filtration mouth of band water storage tank 10, and screen pack is installed in and filters on the mouth; The water mist dust fall device is the high-pressure nozzle of a nozzle towards the gas outlet; The ventilation duct bottom at place, gas outlet has the mud hole 17 of band slag blocking plate 11; Water pump is a high-pressure hydraulic pump; Return pipe is communicated with the water storage tank bottom; The external water source of water inlet pipe.
And the water mist dust fall device is separated by a distance, ventilation duct bottom between water mist dust fall device and the mud hole, can all be set to filter mouthful, several also can be set in this section zone at interval filter mouthful, and several are filtered mouthful water storage tanks of bottom be communicated with pipeline.
In order to prevent that dust-containing water from flowing back to stream, can establish a seal plate 12 in the ventilation duct bottom of filtering between mouth and the water mist dust fall device.
For the water in the cleaned water tank more, can be located at the top of the screen pack in the water tank with stretching into water inlet pipe delivery port in the water tank, current are entered in the water tank by screen pack.
Because during dust removal machine work, be in the continuous uninterrupted state, and the external water source of water inlet pipe, so probably owing to reasons such as carelessness, cause the water in the water tank excessive, influence working environment,, the water controller 13 of a band float 18 is set on can the water inlet pipe in stretching into water tank for fear of this trouble, when the water in the water tank reach a certain height, the float come-up is stopped up water inlet pipe, has disconnected the water source.
For the dust on the screen pack that is deposited in the water tank in time being removed, can open a slag-drip opening 14 in the water tank bottom, like this, the dust on the screen pack, just working water that can constantly be refluxed and external water inlet sweep away from screen pack, discharge with dust-containing water from slag-drip opening.
In order to regulate the wind speed in the ventilation duct, can open a ventilation window 15 on the ventilation duct top between water mist dust fall device and the mud hole.
For dust laden air is fully mixed with water smoke, can a helical runner 16 be set in the ventilation duct between air inlet and the water mist dust fall device, make dust laden air form eddy current by helical runner after, fully mix with water smoke.
