Description
Technical field
The utility model belongs to environmental protection and resource technical field, relates to a kind of desulfation dust-extraction device that is used for prevention and control of air pollution.
Background technology:
Dedusting and desulphurization integrated form is usually adopted in middle-size and small-size flue gas in power station boiler pollution control, perhaps the form of desulfurization again after the dedusting.These desulfation dust-extraction devices are the inverted U structure generally by the bottom air intake, and adopt towers such as rotating stream tray scrubber, turbulence sphere tower more, have circulating water pool, for several boiler smokes are handled shared.Sulfur method then adopts two alkaline process, promptly adopts sodium alkali desulfurization, with the method for lime regeneration.The major defect that exists: the one, desulfuration efficiency is not high, and the NaOH consumption is big, so the operating cost height.The 2nd, flue gas with water is serious, thereby causes faults such as blower fan corrosion.
Summary of the invention
The purpose of this utility model is that a kind of simple in structure, reduced investment, liquid column tower flue gas desulfur device that desulfurized effect is good will be provided.
The utility model is to realize like this, it comprises that the top side has the desulfurization fluid column king-tower of gas approach and the desulfurization secondary tower that top has exhaust opening, it is characterized in that: desulfurization fluid column king-tower and desulfurization secondary tower connect into U font tower body, U font tower body bottom is provided with circulating water pool, and circulating pump, be provided with the desulfurizing agent playpipe that upwards sprays in the described desulfurization fluid column main tower, with the fluid column spraying layer that is positioned at Side under the desulfurizing agent playpipe, the input of described fluid column spraying layer is connected with the circulation delivery side of pump, and the spout of fluid column spraying layer up.
Above-mentioned desulfurizing agent can be sprayed into by the desulfurizing agent playpipe, when using lime desulfurization, can obtain the accessory substance gypsum; When using the magnesia desulfurization, can obtain accessory substance magnesium sulfate.
During work, on the one hand, absorption slurries in the circulating water pool by recirculation pump from the tower bottom sucking-off, the special nozzle of being made by high-abrasive material by the fluid column spraying layer under the effect of pressure is upwards sprayed, form some fluid columns that cover whole absorption tower section, flue gas once contacts washing with slurries this moment, collide and formation high density particulate mutually again in the process that slurries fall after scattering in the fluid column top naturally, gas-liquid contacts with flue gas once more and washs it, finishes slurries and the two overall processes that contact of flue gas in the circulating water pool thus.On the other hand, flue gas enters from tower body top, after the absorption slurries contact purification, again outside demister is discharged to tower.
Liquid column tower flue gas desulfur device of the present utility model is integrated desulfurizing tower and recirculated water, and structural design is comparatively reasonable.Its spray absorption reaction chamber and dehydrating demisting chamber are provided with respectively, thereby have solved the contradiction of desulfuration efficiency and flue gas with water effectively, have promptly avoided after desulfuration efficiency strengthens spray flux the serious problem of flue gas with water being taken place for improving.Feeding compressed air in circulating water pool, is calcium sulfate with the desulfurization product calcium sulfite oxidation, drives the carbon dioxide that is dissolved in the water, has solved the line clogging problem.Because the increase of calcium sulfate concentration drops into a spot of calcium sulfate crystal seed in the early stage, has created condition for the crystallization of calcium sulfate, obtain at last can commercial Application calcium sulphate dihydrate.

The specific embodiment
The utility model liquid column tower flue gas desulfur device, comprise that the top side has the desulfurization fluid column king-tower of gas approach and the desulfurization secondary tower that top has exhaust opening, it is characterized in that: desulfurization fluid column king-tower and desulfurization secondary tower connect into U font tower body, U font tower body bottom is provided with circulating water pool, and circulating pump, be provided with the desulfurizing agent playpipe that upwards sprays in the described desulfurization fluid column main tower, with the fluid column spraying layer that is positioned at Side under the desulfurizing agent playpipe, the input of described fluid column spraying layer is connected with the circulation delivery side of pump, and the spout of fluid column spraying layer up.
For favourable deslagging, improve desulfurized effect, be provided with the desulfurization slag excavationg pump in the described circulating water pool, the mixer and the port of export extend the oxidation air pipe of mixer below, in the described desulfurization secondary tower body demister are installed.Described U font tower body adopts steel design or granite structure.The gas approach of desulfurization fluid column king-tower is connected with preposition deduster, the external air-introduced machine of the exhaust opening of desulfurization secondary tower.
During work, lime (carbide slag) or magnesia are modulated into certain density slurries, are ejected in the desulfurizing tower, the mode of injection is and the flue gas adverse current direction that this process mainly solves desulfurizing agent and evenly distributes and problems of dissolution in tower.Desulfuration recycle pump is extracted desulfurization slurry out from circulating water pool, by liquid column-spraying, contact with flue gas adverse current, in the absorption tower, the absorption slurries upwards spray and downwards with contacting for twice with flue gas in the flow of flue gas process, local liquid-gas ratio is doubled, and the clearance of sulfur dioxide is higher.In the slurries pond, SO2 in the flue gas and the CaO in the slurries and the oxidation air that blasts carry out chemical reaction, and final reacting product is a gypsum.Flue gas after the desulfurization is removed tiny drop through demister, enters chimney.Slurries after the desulfurization can utilize or abandon.
