The specific embodiment

The utility model is by cylindrical shell 14, be connected with cylindrical shape volute 16 in the lower end of housing 14, be connected with conical liquid storage ash collection slot 17 in the lower end of volute 16, in housing 14, be provided with cylindrical shape inner core 5, the lower end of inner core 5 is connected with drain socket 15 by cone 4, be provided with tapered eddy flow guide vane 3 of arranging at drain socket 15 and 16 of volutes, top and 14 of housings at inner core 5 are connected with flap blinds dewatering plate 11, on the volute 16 of housing 4 bottoms, be connected with the smoke inlet pipe mouth 31 that tangentially enters, be connected with the socket 9 of giving vent to anger in the upper end of housing 14, the give vent to anger lower end of socket 9 is stretched in the inner core 5,5 of socket 9 and inner cores are connected with eddy flow guide vane 8 giving vent to anger, in socket 9 lower port of giving vent to anger, be provided with resistance absorber blade 7, be provided with tank 22 in the outside of housing 14, automatic fluid level control valve 2, water circulating pump 1 and water supply line device constitute.

The utility model is further to improve dust removing effects, on housing 14 walls, offer the water inlet 28 and the tank 6 thereof of circle distribution, circle distribution tilts to be connected with one deck bypass channel 27 at least between the cavity of housing 14 madial walls and inner core 5 lateral walls, bypass channel 27 becomes the lath of groove for the cross section, accompanying drawing 1 embodiment is depicted as three layers, when bypass channel 27 is multilayer, every layer of bypass channel 27 is staggered, the water that is flowed out by the water inlet on housing 14 inwalls 28 flows down in housing 14 inner wall surface and forms moisture film, the moisture film that is formed on the outside wall surface of inner core 5 on inner core 5 outer walls guided the water on housing 14 internal faces into by bypass channel 27, and dirty moisture film in time is carried to the flue dust that captures in the liquid storage ash collection slot 17 of bottom.Bypass channel 27 also plays the effect of dewatering plate simultaneously, and the water smoke that absorption contains tiny flue dust is gathered into water droplet.

The utility model is further to improve the desulfurization and dedusting effect, tangentially be provided with plural at least water spout 26 in housing 14 inboards, cavity water spray to 5 of housing 14 and inner cores, strengthen gas, liquid, solid three mixings that contact, the flue dust, sulfur dioxide and the water-setting that promote to strengthen in the flue gas gather absorption.On housing 14 madial walls on water spout 26 tops, be located at water fender 12, stoped the moisture film on the shell wall face upwards to flow.

The utility model is further to improve the desulfurization and dedusting effect, is provided with shower 10 in the chamber, upper end 41 in housing 14, and it is mainly used in the control of dust of cleaning equipment inside, also is used for the intensified dust removal effect simultaneously in case of necessity.

The utility model ash-laden gas is under the effect of air-introduced machine, flue gas is tangentially entered rotation in the volute 16 of housing 14 bottoms by smoke inlet pipe mouth 31, and impact liquid storage ash collection slot 17 liquid levels simultaneously and evoke spray and water smoke, big flue dust directly is deposited in liquid storage ash collection slot 17, flue gas enters in the cavity of 14 of inner core 5 and housings rotation through eddy flow guide vane 3 and rises, grit in the flue gas is inhaled by water smoke and is caught, become drops of water fall down with the water smoke aggegation, diversed blade 3 of while, bypass channel 27, moisture film absorption on housing 14 inwalls and inner core 5 outer walls, flow downstream into liquid storage ash collection slot 17 with moisture film along wall, steam rises and is gathered into water droplet through flap blinds dewatering plate 11, through the gas of dewatering plate 11 housing 14 in chamber 41, upper end (after the purification of shower 10 spray washings) again the eddy flow guide vane 8 through inner core 5 upper ends enter downwards in the inner core 5, and in inner core, rotate, water smoke is thrown toward adsorpting aggregation on inner core 5 walls, and the rotation separation further is gathered into drops of water fall down in inner core 5, and cleaned gas rises through escape pipe 9 and discharges.

The utility model is rational in infrastructure, volume is less, and is easy to use flexible, and impact liquid level, turbulence, liquid film mass transfer, atomizing absorption, spray washing, rotation are separated kinds of processes and combine, make the abundant haptoreaction of gas, liquid, solid, thereby realize efficient desulfurizing and dust collecting.
