Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of high-efficiency desulfurizing dust-collector comprises gas wash tower and desulfurizing tower, and gas wash tower and desulfurizing tower lower end are by tower reactor race way 4 UNICOMs.Gas wash tower comprises air intake flue 1, dedusting area 2 and cooling area 3 from top to bottom successively, is respectively equipped with circulating water intake in air intake flue 1 bottom and cooling area 3, is provided with two-layer eddy flow tray in the cooling area 3, and the air intake flue is Venturi tube; Desulfurizing tower comprises desulfurization zone 5, demist dehumidification district 6 and chimney 7 from top to bottom successively, and demist desulfurization zone 6 tops are provided with the flushing water import, and the flushing water import is communicated with flushing water, is provided with two-layer eddy flow tray in the desulfurization zone 5; 4 bottoms, tower reactor race way are provided with sewage draining exit.
Circulation comprises lime slurrying pond 8, regenerated reactor 9, sedimentation basin 10 and the clean solution tank 11 of successively series connection, and by pipeline and desulfurization water pump 12 and clean solution tank 11 connections, sewage draining exit is communicated with by pipeline and regenerated reactor circulating water intake respectively.Clean solution tank adds soda by the soda entrance, and sedimentation basin exports desulfurization slag by desulfurization slag, and lime slurrying pond adds fresh water (FW) and lime by fresh water (FW) import and lime entrance.
The course of work: recirculated water sprays by the desulfurization water pump and enters the Venturi tube bottom, form negative pressure in the Venturi tube, the recirculated water that ejects forms water smoke, water smoke can effectively force to catch the dust in the flue gas, flue gas enters Venturi tube by tangent plane and directly contacts also fully mixing with water smoke, water droplet condenses the SO in the flue gas in grit under high velocity air impacts in the flue gas and the water smoke
2Neutralize with the alkaline components in the water smoke.Be provided with two-layer eddy flow tray in the cooling area, cooling area is connected with circulation, circulating water intake is positioned at each place, eddy flow tray top and is equipped with a plurality of spray nozzles that are positioned on the same level face, in the time of in the middle of flue gas enters two-layer spiral board, utilize the air-flow guide effect of spiral board and the downward screw of flue gas self that the doctor solution on the spiral board is dispelled, atomizes, make and form one section desirable atomizing zone on the spiral board, the desulfurization absorption liquid exists with the droplet of tens microns sizes in this zone, greatly increase the gas-liquid contact area, thereby guaranteed the SO in the flue gas
