Description

Smoke and dust purifying device

The utility model relates to the improvement of device for eliminating smoke and dust.

In industry production processes such as metallurgy, non-ferrous metal, cement, produce a large amount of flue dust, adopt two-stage dust removal that flue dust is carried out purified treatment usually.The first order is large-scale cooling tower, only reduces the temperature of flue dust with water cooling in this tower, for the next stage dedusting is prepared; The second level is electrostatic precipitation or dust removal by filtration.Its shortcoming is that technological process is long, and equipment is more, and consumes energy is big, and takies a large amount of investments and operating cost.

The purpose of this utility model is exactly at the problems referred to above, and a kind of simple in structure, compact, purification flue dust device that efficient is high is provided.

The purpose of this utility model is achieved in that exactly existing process for cooling, dust collecting process to be incorporated in the cooling tower carries out simultaneously, promptly the top in tower is provided with corona zone and activation cooling water jet unit, realizes above-mentioned purpose of the present utility model with this.

Between the pole plate of corona zone, can pass through high voltage narrow pulse, produce particulate in a large amount of electronics and the bombardment by ions flue dust, moment makes it charged, charged flue dust mixes the formation air curtain with the rotation activated water, move at the bottom of tower from cat head, in running, because charged grit static cohesion is strengthened greatly, the volume of grit can increase several times to tens times.Like this, flue dust is through corona zone, activated water inlet zone, become temperature lower, have a large amount of oarse-grained flue dust, reduce to tower bottom.

Because flue dust carries out above-mentioned integrated treatment at Ben Tanei, improved the efficient of purification flue dust greatly, and saved a large amount of equipment, thereby reduced manufacturing cost and operating cost.

Below in conjunction with accompanying drawing concrete structure of the present utility model is further described:

The utility model comprises tower body 10, tower body 10 comprises air intake 14, air outlet 8, depositing dust mouth 1, high pressure generator 5 links to each other respectively with discharge plate 15, the dust collecting pole plate 13 at tower body 10 tops, water pipe 18 links to each other with the water spout 11 at tower body 10 tops, and water pipe 18 sides are respectively arranged with pump 16 and strong magnetic tube 17, high-frequency generator 19.

Water spout 11 can be provided with a plurality of on the tower body in the same plane 10, and can be the tangential direction setting, makes activated water be easy to fully mix mutually with flue dust.

High pressure generator 5 also can link to each other with the pre-charge device 12 on the tower body 10 between discharge plate 15, dust collecting pole plate 13 and the water spout 11, owing to have powerful electrostatic field in the pre-charge device 12, just produce a large amount of electronics and anion 21 thereupon, make the charged grit 20 of the further charged one-tenth of flue dust, flue dust is easier to combine with activated water, produces the dust removing effects of lowering the temperature even more ideally.The number of pre-charge device 12 can be determined than the size of resistance according to flue dust.

Pre-charge device 12 comprises housing 22, and discharge electrode 25, positive pole 23 are set in the housing 22, on housing 22 inwalls insulating barrier 26 is set, and housing 22 sides are provided with blast pipe 27; Also can have prickle 24 on the discharge electrode 25, with this enhanced discharge effect.

Water spout 11 comprises mouth body 29, and mouth body 29 comprises water inlet 28, delivery port 32, and the side of water inlet 28 is an air inlet 30, has sprinkling head 31 in the delivery port 32.After water enters mouth body 29 from water inlet 28, through the air of air inlet 30 blow, the effect of sprinkling head 31 is vaporific and is sprayed onto outside the delivery port 32.

Tower body 10 bottoms are provided with static networking deduster 2, and networking deduster 2 comprises housing 6, have the tube 4 that gathers dust in the housing 6, and the tube 4 that gathers dust is with being the oblique ash-pit 7 that leaks between the housing 6, and housing 6 tops are dust-catching board 9, and the side of housing 6 is a supporter 3.

High pressure generator 5, strong magnetic tube 17, high-frequency generator 19 all can be purchased from market.High-frequency generator 19 can adopt the DXG-4 model.

Through the flue dust of the air inlet 14 of tower body 10, the activated water water spray district that forms through discharge plate 15, dust collecting pole plate 13 formed corona zones and water spout 11 again makes charged grit 20 and is able to fully mix with activated water; Again under the effect of tower internal pressure differences, drive charged flue dust and flow to deduster 2 to tower body 10 bottoms, above air outlet 8, reached the cooling requirement, flue dust sedimentation some, the flue dust that is not removed, above air outlet 8, at first attracted by the dust-catching board 9 of positively charged position, by the rapping grit enter oblique slide ash-pit 7 flow to enclosed type gather dust the tube 4, flue dust is by dust collection plate 9 wind speed decreased, and turn to the electrostatic precipitation endless loop, by further dedusting, dust is then discharged from depositing dust mouth 1, and the flue dust of air outlet 8 also can be imported next stage and further purify.
