Abstract
The invention belongs to the field of industrial dust removal and discloses a cyclic wet filtration dust remover. The cyclic wet filtration dust remover is mainly characterized in that a dust collection cover is arranged above a dusting point and is communicated with a dust absorption pipe; an atomizing nozzle is arranged at the inner front part of the dust absorption pipe; front-stage and back-stage cyclic dust filtration screens are arranged in the downstream direction of the atomizing nozzle; a washing nozzle is arranged at the back of a screen surface of each cyclic dust filtration screen; an ash removal hopper is arranged below each cyclic dust filtration screen; a dust absorption fan is connected to the rear part of each cyclic dust filtration screen. The cyclic wet filtration dust remover has the advantages of reasonable structure, combination of dust removal functions, good dust removal effect, stable performance, small maintenance amount, energy conservation, environmental friendliness and the like.
Description
Technical field
The invention belongs to the industrial dedusting field, relates to power plant's coal handling system dust arrester, specifically is the wet filtering dust collecting machine of a kind of circulation.
Background technology
According to statistics, use sack cleaner in the present domestic power plant coal handling system, the ratio of electrostatic precipitator and wet type wet dust collector reaches 80%, but moves devoting rate less than 50% still, and operational effect is not good.Three class dedusting technologies existing problems are as follows:
Sack cleaner wherein
1) because coal dust humidity and cloth bag eye high velocity air by easily forming the dewfall factor, are stained with stifled cloth bag eye easily, safeguard and when changing cloth bag workload bigger,
2) the equipment pressure loss is big, and institute's gas-distributing fan power is big, the energy consumption height,
3) continuous service for a long time needs the periodic replacement cloth bag.
Wherein, electrostatic precipitator
1) cost height, the investment cost height,
2) because electrostatic precipitator requires the very low wind speed that passes through, therefore bulky, be not suitable for the narrow space mounting at coal handling system,
3) cause the spontaneous combustion blast easily for the treatment of coal dust,
4) wind speed can not be too high, otherwise efficiency of dust collection seriously descends, and can not form that enough negative pressure are dustproof to escape,
5) because electrostatic precipitator is subjected to the influence of dust resistivity, dust there is certain selectivity, and the polar curve pole plate dust stratification that makes moist, can't carry out deashing, cause discharge performance to decline to a great extent like this.
Wherein, water-bath type dust cleaner
1) power of fan is big, the energy consumption height,
2) water consumption is big, and fan belt water is serious,
3) owing to reasons such as water source calcic easily cause pipeline blockage, continuous firing for a long time.
In order to solve the problem that domestic power plant coal handling system dedusting present situation exists, the technical scheme that the invention is taked is the wet filtering dust collecting machine of a kind of circulation of design, its structure comprises: frame, in frame dust collection cover is set, be connected with dust collection cover sweep-up pipe is set, in the front portion of sweep-up pipe, atomizer is set, pharmacy jar is connected with the water inlet pipe of atomizer, prime circulation dirt filtrating screen and back level circulation dirt filtrating screen are set in the downstream of atomizer, wire side back at prime circulation dirt filtrating screen and back level circulation dirt filtrating screen arranges flooding nozzle, below prime circulation dirt filtrating screen and back level circulation dirt filtrating screen ash bucket is set, the rear of circulation dirt filtrating screen is connected with dust absorption fan after level.
The wet filtering dust collecting machine of this circulation that the invention is designed, during use, dust collection cover is installed in the workshop material to be risen on the dirt pits, during work, under the effect of dust absorption fan, dust laden air in the dust collection cover enters sweep-up pipe, entered the dust laden air of sweep-up pipe before arriving prime circulation dirt filtrating screen, at first through atomizer catch dirt or the atomizing liquid medicine (such as foaming agent, desulfurizing agent etc.), with the toxic component that strengthens the deduster effect and remove pernicious gas, atomizer produces water smoke, with the dust collision combination of process, dust contains grey water droplet at this district's coacervating large particle, contains buck and drops in the gravity effect landing of sinking and go into ash bucket and discharge.Water smoke sprays prime circulation dirt filtrating screen and forms moisture film (can produce foam if add foaming agent) at filter screen, and part is caught by moisture film when the dust arrival prime circulation dirt filtrating screen surface of dirt escape is caught in atomizing.From the comparatively clean air that prime circulation dirt filtrating screen passes through, also contain part water smoke and small amount of dust, this part dust-laden air contained water during by back level circulation dirt filtrating screen water smoke form moisture film at filter screen again, dust further is hunted down.The effect of back level dirt filtrating screen mainly separates with small amount of dust water smoke from air.Pure air after the dirt of level filter later dirt filtrating screen further filters enters atmosphere by dust absorption fan, contains buck and is dropped into ash bucket and discharges.Prime circulation dirt filtrating screen and back level circulation dirt filtrating screen be cycle rotation separately, and flooding nozzle carries out online wash cycles to the wire side of circulation dirt filtrating screen in case of necessity, guarantees that the filter screen working face is in clean conditions, realizes working continuously for a long time.
This circulation of the invention filtering dust collecting machine that wets, level gyration dirt filtrating screen is caught dirt in conjunction with atomizing before and after adopting, and moisture film is caught dirt, foam arrested dust and sterilizing and purifying, adopt circulation dirt filtrating screen gyration operation, filter screen working face on-line cleaning realizes working continuously, and has rational in infrastructure, good dedusting effect, stable performance, maintenance is few, remarkable advantages such as energy-conserving and environment-protective.
