Dust-removal and desulfurizing Environment protection chimney is to belong to field of Environment Protection, and a kind of equipment of purification is provided to coal-fired flue-gas
At present both at home and abroad smoke dust-removing desulfurization equipment, is all independently cleaner and the wet desulphurization equipment cascaded structure being arranged in parallel on ground, and wet desulphurization equipment system is also the cascaded structure of desulfurizing tower and concentration basin, oxidation pond, slurrying pond horizontal layout.Taking up an area the ground multistage pump that is flowing in large, spray liquid is connected in series.Power consumption is high, investment is large.
The present invention does not exist together with general cleaning equipment maximum;
1, will in the equipment of flue gas ash removal, desulfurization, armamentarium series connection structure in a vertical vertical circle, polygon chimney, complete.
2, tower peripheral hardware oxidation pond is originally in the oxidation of spray liquid, enters oxidation pond be oxidized sulfur dioxide secondary pollutant with air blast drum air.The present invention completes oxidation with spray liquid at the vertical-overflow ingress of air of the top concentration basin of concentrated, oxidizing tower.
3, smoke-gas wet desulfurization directly discharges vaporific flue gas after being originally spray column.
The present invention is that the vaporific flue gas after spray column purifies with wet electrostatic device more again, and vaporific gas cleaning is discharged to water white transparency state.
The object of dust-removal and desulfurizing Environment protection chimney;
By pollutant harmful in flue gas; Solid particle, harmful liquid droplet, pernicious gas SO2 approach 100% and separate.Discharge water white transparency saturated flue gas.
The embodiment of dust-removal and desulfurizing Environment protection chimney;

Case; Medium; Coal-fired flue-gas
Flue gas enters spray column (1), uses the vaporific spray flue gas of spray system (5) in spray column (1).
Flue gas after spray becomes vaporific flue gas, rise into wet electrostatic tower (2) in wet electrostatic tower (2), the liquid of the various particle diameters that suspend in vaporific flue gas, solid particle are adsorbed pole plate 100% and adsorb, converge, increase the bulky grain of hundred times, under Action of Gravity Field, concentration basin (6) is entered in vertical landing
Water white transparency saturated flue gas after static rises into intensification tower (4) from wet electrostatic device (2) outlet,
In intensification tower (4), flue gas becomes unsaturated transparent fume emission after heating up.
In spray column (1), with the liquid vertical landing of the vaporific spray of spray system (5), enter the concentration basin (6) on concentrated oxidizing tower (3) top
Solid particles sediment is at the bottom of pond in concentration basin (6) for spray liquid, and concentration basin (6) outlet at bottom is entered in landing, enters auger or dewaterer (8) discharge.
Spray liquid is clarified spray liquid and from top overflow inclined hole (14), is overflowed to the exterior wall (12) of concentrated oxidizing tower (3) in concentration basin (6), then under vertical current, arrives the chute of bottom.Overflow layer (13) ingress of air, completes oxidation and the heat exchange of spray liquid.Generate 2 water gypsum particles, reduce water outlet simultaneously, with overflow layer (13) vertical current influent stream groove.
In chute, slurry is crossed the circulatory pool (7) that open-work enters tower inner bottom part
Circulatory pool (7) grinder system (10) above discharges the desulfurizing agent slurry grinding into the circulatory pool (7) of bottom
The desulfurizing agent slurry that circulatory pool (7) mixer (11) above grinds grinder system (10) stirs in circulatory pool (7).
Circulatory pool (7) circulating pump (9) above boosts the spray liquid after stirring in spray column (1), with the vaporific spray flue gas of spray system (5),
