Abstract
The utility model discloses a dedusting and desulfurization plant, which comprises a dedusting device with an air inlet and an exhaust outlet, which is communicated with a kiln smoke vent. The dedusting device comprises a dedusting tower, a fume transition tower and a thionizer, which are orderly arranged in parallel. A smoke passage is mad into an S-shaped structure by openings, which are respectively positioned on the dedusting tower, the upper part of the lateral wall of the fume transition tower and the lower part of the lateral wall of the fume transition tower and the thionizer. Filter screen layers are horizontally positioned in chambers of the dedusting tower and the thionizer respectively. A spray device, which is positioned at the dedusting tower and the upper end of the cavity of the fume transition tower, is communicated with a circulating water basin under a water discharge port, which is arranged on the dedusting tower and the bottom of the dedusting tower and the fume transition tower, through a deducting pipeline. A desulfurization sprayer on the upper end of the thionizer cavity is communicated with a desulfurization water basin under a water discharge port at the bottom of the thionizer through a desulfurization pipeline. By using the utility model, which has the advantages of simple structure, low cost, small land occupation, non residue and exhaust liquid retaining, the fly ash deposit can be re-burnt and reutilized after being mixed with the dry coal and the environmental protection requirement is met.
Description
Technical field
The utility model relates to the dust arrester of coal-fired furnace flue gas, especially relates to a kind of dust-removing desulfurating apparatus of purifying flue gas body.
Background technology
In the flue gas that discharge flue is discharged, contain a large amount of flyash and harmful substance during the work of various coal-fired furnace, if let alone to be emitted in the atmosphere, will major polluting atmosphere environment, so the dust arrester of various structures arises at the historic moment.In use, some dust arrester effect is bad, does not reach the purification purpose, though some good dedusting effect, cost is very high, is unfavorable for applying at medium-sized and small enterprises.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, cost is low, result of use is good dust-removing desulfurating apparatus.
For achieving the above object, the utility model can be taked following technical proposals:
Dust-removing desulfurating apparatus described in the utility model, comprise the dust arrester that has air inlet and exhaust outlet that is connected with the kiln smokejack, gas wash tower, smog transition tower and the desulfurizing tower of described dust arrester for being set up in parallel successively, the opening that is opened in gas wash tower, smog transition tower side wall top and smog transition tower, desulfurizing tower lower sidewall respectively made the S-shaped structure of cigarette channel; In the chamber of gas wash tower and desulfurizing tower, be horizontally disposed with filter mesh layer; The spray equipment that is provided with in gas wash tower and smog transition tower inner chamber upper end is connected with circulating water pool below being arranged on gas wash tower and smog transition tower bottom discharge outlet by the dedusting pipeline; The desulfurization shower nozzle that is provided with in desulfurizing tower inner chamber upper end is connected with desulfurization pond below the desulfurizing tower bottom discharge mouth by the desulfurization pipeline.
For making things convenient for, in the desulfurization pond, adding desulfurizing agent timely, guarantee desulfurized effect, described desulfurization pond is connected with the desulfurizing agent regenerating tank by pipeline.
For making things convenient for the cleaning of dirt in the pond, the bottom in described circulating water pool and desulfurization pond offers sewage draining exit.
For guaranteeing the spray effect, in the pipeline of described dedusting pipeline and desulfurization pipeline, be provided with force (forcing) pump.
Advantage of the present utility model is that the dense smoke that the kiln smokejack is discharged enters gas wash tower from air inlet, water or Ca (OH) in the circulating water pool
2Alkaline solution sprays to the tower body inner chamber to spray equipment through the dedusting pipeline, on filter mesh layer, be covered with uniform liquid film, when upwards breaking through filter mesh layer, air-flow evokes spray and water smoke, gas, liquid are fully contacted, in cooling, fine particle is become larger particles with fixed attention, return and drop on the filter mesh layer, play the effect of dedusting, simultaneously Ca (OH)
2With SO
2The reaction back generates CaSO
3, can also remove harmful substances such as partial vulcanization thing; Treat that air-flow rises to the top and enters smog transition tower inner chamber, under the effect of spray equipment, gas, liquid are further contacted, strengthen cooling, collision effect, increase dust removing effects; After at the bottom of air-flow is reduced to tower, entering desulfurizing tower, owing in the desulfurization pond, added desulfurizing agent, filter mesh layer will be done once more removing to remaining in harmful substances such as sulfide in the flue gas, guarantee that the air cleaning that is discharged in the atmosphere is up to standard, reach the purpose of thorough dust-removal and desulfurizing.This apparatus structure is simple, and cost is low, and floor space is little, and the flyash sediment of discharging in circulating water pool and desulfurization pond can mix the utilization of flashing back the dry coal, does not stay any residue and waste liquid, can not produce secondary pollution, meets country to environmental protection requirement.
