Description

The water smoke dust arrester installation

Technical field

The utility model relates to a kind of dust-collecting and dust-removing device, refers in particular to the device with wet dust collector.

Background technology

In industrial processes, the dust pollution that emits air, allow many people, animal cause multiple disease, make many crop production reductions in poor harvest.The dust that emits as the cement plant can produce in reclaiming, if without reclaiming directly discharging, both contaminated environment was wasted resource again.At present, the big-and-middle-sized producer that has dust emission to pollute of China mostly makes the electricity consumption dust arrester installation come dust-collecting and dust-removing.But there are following several point defects in electric dust arrester installation: 1. dust collection effect is poor, with the cottrell that is applied in cement industry is example, the dust that cottrell is regained, through multiple working procedure dust is put in storage, with elevator dust is mentioned in the very high storage warehouse, with gases at high pressure dust is imported in the cement Dayao again, so big air pressure enters in the Dayao together with dust, grain dust in the kiln all blown out get back in the cottrell again, the dust of cement Dayao discharging is circulated within cement Dayao and the cottrell like this, so both increase the workload of cottrell, reduced the dust collection effect of cottrell again.2. cottrell power consumption is too big, and start a cottrell and need consume 60,000 volts of high-tension electricities, the electromagnetic field of its generation human magnetic field of can confusing, very harmful to operator's psychosomatic health.3. cottrell is out of order easily, and maintenance is inconvenient.

Summary of the invention

The purpose of this utility model just provides the dust arrester installation that a kind of dust collection effect is good, power consumption is low, easy to maintenance.

Main technical schemes of the present utility model is as follows: the water smoke dust arrester installation, be made up of extractor fan and working bin, water injector, extractor fan is by air draft pipe and the exhaust blower and the motor that are contained in dust sensor in the air draft pipe, transpose valve and are contained in the air draft pipe tail end are formed; Working bin is divided into dust-collecting bin and dust storehouse, dust-collecting bin is positioned at the top of dust storehouse, is provided with motor on the Cang Ding of dust-collecting bin, and the output shaft of motor stretches in the dust-collecting bin, the coaxial dust catcher that is with on its output shaft has air inlet, air outlet and sprayer aperture on the warehouse of dust-collecting bin; The warehouse of dust storehouse is equipped with motor outward, this driven by motor is contained in the reduction box in the dust storehouse, on the output shaft of reduction box, cleaning shoe is housed, the dust storehouse bottom has mud mouth, the bottom of mud mouth is provided with mud conveying pipeline, spiral reamer by driven by motor is housed in the pipeline, elastic pulp exit and following mud mace is housed at the tail end of dredging tube; Water injector is made up of high-pressure hydraulic pump and the hydrostate and water spray valve, the sprayer that are installed on the high-pressure water pipe, and the water smoke that sprayer sprays is sprayed in the dust-collecting bin by the aperture on the dust-collecting bin.

It is good to the utlity model has dust collection effect, and power consumption is low, advantage easy to maintenance.

The specific embodiment

As shown in the figure, the water smoke dust arrester installation is made up of extractor fan and three working bins, water injectors.Extractor fan is made up of air draft pipe 1 and the exhaust blower 13 and the motor 22 that are contained in dust sensor 2, the flue dust positioning valve 7 in the pipeline and are contained in the air draft pipe tail end.Three working bins connect by air draft pipe, by the positioning of the flue dust in air

draft pipe valve

29,30,31,32,33, the air inlet and the air outlet of 34 each working bins of control, each working bin is divided into dust-collecting bin 5 and dust storehouse 4 two parts, dust-collecting bin 5 is above dust storehouse 4, on the Cang Ding of dust-collecting bin 5, be provided with motor 6, the output shaft of motor stretches in the dust-collecting bin 5, the coaxial dust catcher 8 that is with on its output shaft, dust catcher 8 is shape in the shape of a spiral, on the warehouse of dust-collecting bin 5, have air inlet, air outlet and sprayer aperture, the warehouse of dust storehouse 4 is equipped with motor 9 outward, this driven by motor is contained in the reduction box 10 in the dust storehouse 4, cleaning shoe 11 is housed on the output shaft of reduction box 10, dust storehouse 4 bottoms have mud mouth, be provided with dredging tube 12 in the bottom of mud mouth, be equipped with in the pipe and connect reduction boxes 14 by motor 23 by belt pulley 24 and drive spiral reamers 15, elastic pulp exit 17 and following mud mace 16 are housed at the tail end of dredging tube.Water injector is by high-pressure hydraulic pump 27 and be installed in hydrostate 25 on the high-pressure water pipe and water spray valve 35, sprayer 26 are formed.The water smoke of sprayer 26 ejections is sprayed in the dust-collecting bin 5 by the aperture on the dust-collecting bin 5.

To be applied in the cement plant is example, the dust that emits when cement in vertical kiln 28 is during by the exhaust blower 13 inspiration exhaust columns 1 of air draft pipe afterbody, be installed in the dust sensor 2 in the exhaust column, the data input computer 3 of cement in vertical kiln discharging dust, computer sends the instruction of water spray immediately to hydrostate 25, at this moment motor 6 runnings drive dust catcher 8 rotation at a high speed in the dust-collecting bin 5, sprayer 26 is by aperture water spray in dust-collecting bin simultaneously, because the centrifugal force that dust catcher 8 is produced when rotating at a high speed, except getting rid of the wet mud of self being stained with, some wet mud is got rid of on the inwall of dust-collecting bin 5, by the trowel of scraping that is installed in the dust catcher outer the wet mud on the inwall is scraped in the dust storehouse 4, scraper in the dust storehouse 4 is slowed down by motor 9 and drives, wet mud in the dust storehouse 4 are all scraped in the mud conveying pipeline below the mud mouth, be transported to and wash in a pan in the mud sump 19 by the rotation of the mud conveying pipeline inside spin reamer mud that will wet, motor 21 drives by reduction box 18 and washes in a pan 20 microrunnings of mud plate, the humidity required according to the cement Dayao adds and sends mud to the Dayao calcination of cement clinker by slush pump 36 after water is washed in a pan into mud.

The quantity of the working bin of water smoke dust arrester installation can be installed according to the different needs of different enterprises, can improve dust collection rate so on the one hand, on the other hand when one of them working bin breaks down the needs maintenance, can open flue dust positioning valve, allow dust enter other working bin and continue to gather dust, do not need stop production to overhaul.In addition, this water smoke dust arrester installation is applied in the industrial and mining enterprises that other has dust pollution, need not use devices such as washing in a pan mud sump and naughty mud plate during as aspects such as smelting, chemical industry, chemical fibre, thermal power generation, coking.
