Abstract
The invention discloses a dust removal method of a wet dust collector. The defect of the wet dust collector includes that slurry discharged from the wet dust collector needs to be disposed, and secondary pollution is caused otherwise. The dust removal method of the wet dust collector comprises the following steps that gas with dust enters the dust collector from an inlet, under the action of guide vanes, airflow turns and impacts a water surface downwards, a part of large dust particles fall into water, when the gas with dust passes through a channel S between the upper vane and the lower vane at the speed ranging from 18m/s to 35m/s, a large amount of water splashes, so that the water makes full contact with the gas, most of micro dust is mixed into the water, and therefore the gas with the dust is purified; after passing through the channel S, the water with the dust particles returns to a funnel due to the action of the centrifugal force; small part of micro dust upwards impacts along with the airflow and is captured by a stuffing, and the dust absorbed on the stuffing falls back to the funnel under the action of high-pressure spray; clean gas is discharged from a chimney after being dewatered by a water baffle. The dust removal method of the wet dust collector is used for wet dust removal.
Description
technical field:
the present invention relates to a kind of dust collection method of wet scrubber.
background technology:
the wet scrubber manufacturing cost is relatively low.But for chemical industry, spray paint, the dust with moisture content, viscosity and penetrating odor that the industries such as glaze spraying, pigment produce is optimal dedusting method.Because not only can remove dust, also can utilize water to remove a part of peculiar smell, if harmful gas (as a small amount of sulfur dioxide, salt acid mist etc.) can be prepared absorbent and absorb in cleaning solution.Shortcoming:
(1) the mud of discharging from wet scrubber will be processed, otherwise can cause secondary pollution;
(2) when purification has subversive gas, chemical corrosion is transferred in water, so sewerage will be protected with anti-corrosion material;
(3) do not conform to for the hydrophobicity flue dust; For the viscosity flue dust, make easily pipeline, blade etc. stop up; |
(4) need to consume water with the dry collector analogy, and process a difficult problem, at severe cold area, should adopt antifreezing measures.
cJSC Swashing type wet dust collector is in conjunction with the advantage of Swashing type and water-bath type dust cleaner, and efficiency of dust collection all is improved largely with respect to single group Swashing type or water-bath type.It is by exquisite structural design, and by the various mechanism of deduster, as collision, diffusion, coalescence, gravity and centrifugation effectively combine, and by the air-flow self-excitation water surface, solution-air, solid-liquid is fully merged, and is convenient to grit and is combined with water droplet.
summary of the invention:
the dust collection method that the purpose of this invention is to provide a kind of wet scrubber.
above-mentioned purpose realizes by following technical scheme:
a kind of dust collection method of wet scrubber, dusty gas enters deduster by entrance, air-flow is turned and is impacted the water surface downwards under the effect of stator, the larger grit of part falls into the water, when dusty gas evokes a large amount of sprays with the speed of 18-35m/s during the S passage by upper and lower blade, aqueous vapor is fully contacted, overwhelming majority micronic dust is sneaked in water, makes dusty gas be able to abundant purification; After the S passage, due to the effect of centrifugal force, the water that obtains grit returns to again funnel; The fraction micronic dust upwards impacts with air-flow, by filler, is trapped, and is adsorbed on during dust on filler falls back to funnel under the effect of high-pressure spraying; Clean gas, after water fender dewaters, is discharged from chimney.
beneficial effect:
1. the present invention is the two-stage dedusting, and efficiency of dust collection is high, and the dedusting resistance is low, and power consumption is few.
2. part standard of the present invention, maintenance cost is low.
3. outlet water orifice diameter of the present invention is large, is difficult for stopping up.
4. floor space of the present invention is little, easy for installation, reliable, long service life.
5. exit gas of the present invention is without water phenomenon.
6. the present invention is applicable to purify the non-corrosive temperature of non-fiber not higher than the dusty gas of 300 ℃, be applicable to the enterprises such as metallurgy, non-ferrous metal, coal, chemical industry, casting, generating, construction material and refractory material, also can obtain good effect in the dedusting for the sticking quick lime of tool transportation system, this is the another outstanding advantages of this unit.
the accompanying drawing explanation:
accompanying drawing 1 is the structural representation of wet scrubber of the present invention.
the specific embodiment:
embodiment 1:
a kind of dust collection method of wet scrubber, dusty gas enters deduster by entrance, air-flow is turned and is impacted the water surface downwards under the effect of stator, the larger grit of part falls into the water, when dusty gas evokes a large amount of sprays with the speed of 18-35m/s during the S passage by upper and lower blade, aqueous vapor is fully contacted, overwhelming majority micronic dust is sneaked in water, makes dusty gas be able to abundant purification; After the S passage, due to the effect of centrifugal force, the water that obtains grit returns to again funnel; The fraction micronic dust upwards impacts with air-flow, by filler, is trapped, and is adsorbed on during dust on filler falls back to funnel under the effect of high-pressure spraying; Clean gas, after water fender dewaters, is discharged from chimney.
embodiment 2:
described wet scrubber, liquid state or solid particles that wet scrubber can be 0.1-20 microns by diameter are effectively removed from air-flow, simultaneously, also can remove the part gaseous contaminant.It has simple in structure, floor space is little, operation and easy to maintenance and purification efficiency advantages of higher, can process the air-flow of high temperature, high humidity, what will catch fire, explode may minimize.But to pay special attention to the problems such as processing of e-quipment and pipe corrosion and sewage and mud while adopting wet scrubber.The wet dust removal process also is unfavorable for the recovery of byproduct.If equipment is arranged on indoor, the problem that also must consideration equipment may freeze in winter.Moreover, if it is also higher to remove the efficiency of subparticle, need liquid phase is better disperseed, but energy consumption increases.
Claims (1)
1. the dust collection method of a wet scrubber, it is characterized in that: dusty gas enters deduster by entrance, air-flow is turned and is impacted the water surface downwards under the effect of stator, the larger grit of part falls into the water, when dusty gas evokes a large amount of sprays with the speed of 18-35m/s during the S passage by upper and lower blade, aqueous vapor is fully contacted, overwhelming majority micronic dust is sneaked in water, makes dusty gas be able to abundant purification; After the S passage, due to the effect of centrifugal force, the water that obtains grit returns to again funnel; The fraction micronic dust upwards impacts with air-flow, by filler, is trapped, and is adsorbed on during dust on filler falls back to funnel under the effect of high-pressure spraying; Clean gas, after water fender dewaters, is discharged from chimney.
