The beneficial effects are that: 1 )Have and remove dust and two kinds of functions of desulfurization. 2 )Remove dust, the desulfurization is efficient. This dust removal process can catch the dust particle degree of 0.5 -1 micron, and general water drenches, lector, whirlwind are removed dust gets rid of the grain more than 5 microns. The high -efficient of event this dust collection efficiency 98% is removed dust. 3 ) water level control, dirt log raft go out full automatic control, and degree of automation is high. 4 )Equipment is difficult to be blockked up, during the shut down, and restart, the no -load operation, but paste the dust and dirt of living in the automatic clear dust remover. 5 )The dehydration and the integration of removing dust, it is efficient to dewater, has guaranteed the dust particle and can not discharge along with the aqueous vapor.

Description

Furfural dregs boiler combustion desulfurating dust removing device for flue gas

Technical field

The utility model belongs to technical field of environment protection equipment, relates to a kind of improvement of emission-control equipment.

Background technology

With corn core be raw material extract furfural be worth higher important industrial chemicals, it is widely used in multiple production fields such as agricultural chemicals, medicine, petrochemical industry, food additives, casting, be the chemical project that a kind of technique is simple, pollution is heavy, the fast development of the sector has caused serious environmental pollution and ecological disruption.

Take furfural dregs as the boiler of fuel, smoke evacuation is containing a large amount of lightweight micronic dust, its very light in weight, inertia is very little, conventional dust removal device is difficult to be removed, all kinds of individual event dedusting technologies such as such as gravitational dust collection, inertial dust collection, cyclone dust removal, dry dust removal or wet dust removal, for lightweight micronic dust and the sulfur dioxide gas of the lightweight as fog, very difficult seizure is removed.Furfural production producer does not solve boiler flue gas purification problem, is that furfural produced by raw material with corncob, the restriction that be stopped production.Furfural producer domestic at present generally faces this problem.

Summary of the invention

The purpose of this utility model is: provide a kind of furfural dregs boiler combustion desulfurating dust removing device for flue gas, the flue dust that the boiler that furfural dregs can be fuel by it produces carries out environmental purification process.

The technical solution of the utility model is: in tubular atomized cover, be provided with several arc whirl cylinder, each whirl cylinder is communicated with, two nozzles are installed in air intake vent, nozzle is towards whirl cylinder, water level controller (LC) is provided with at support body rear portion, be provided with overflow device in support body bottom, whirl cylinder is communicated with overflow outlet by dust collecting trough.

The beneficial effects of the utility model are:

1) there are dedusting and desulfurization two kinds of functions.

2) dedusting, desulfuration efficiency are high.This dust collecting process can catch the grit degree of 0.5---1 micron, and general water pouring, lector, cyclone dust removal remove grain more than 5 microns.Therefore the high-effective dust-removing of this efficiency of dust collection 98%.

3) water lev el control, dirt water discharge Automatic Control, and automaticity is high.

4) equipment not easily blocks, and during shutdown, restarts, no-load operation, can automatically remove the dust and dirt touched in deduster.

5) dehydration is with dust removal integrated, and dewatering efficiency is high, ensure that grit can not be discharged with aqueous vapor.

Fig. 2 is the main sectional view of the utility model;

Fig. 3 is the utility model left view.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, 1 be manhole, 2 are nozzles, 3 are air intake vents, 4 are air outlets, 5 are whirl cylinders, 6 are water level controller (LC)s, 7 are support bodys, 8 are overflow devices, 9 are atomized covers, 10 are overflow outlets, 11 is dust collecting troughs.

Flue gas after furfural burning, rush at the water surface of the first whirl cylinder, enter from air intake vent 3, waste gas blows and sprays on whirl cylinder 5 by the nozzle 2 in air intake vent 3, under the effect of high-temperature flue gas, water smoke is vaporized, enter whirl cylinder 5, in whirl cylinder 5, due to the expansion of sectional area, the flow velocity of air-flow lowers, along with the increase of humidity, the decline of temperature, when dropping to below 1000c, take grit as core, be condensed into droplet, or be deposited at the bottom of room, or introduce furfural dregs deduster with air-flow, achieve the pretreatment of flue dust, effectively fine dust is condensed, dirt is with wet dirt state, increase the proportion of grit, vital effect is played to the seizure of this type of flue dust.Grit in flue gas enters in water, simultaneously at the droplet of dirt condensing chamber cohesion, also enters in water simultaneously, is captured.The flue gas entering whirl cylinder rolls water smoke again, rotates in cylinder, and flue gas mixes further with the water in cylinder, and under the effect of centrifugal force, dirt water flows into the water surface along barrel.And constantly discharge from dust collecting trough 11 end.Flow to precipitation pond.Equipment has level Four whirl cylinder, carries out the seizure of four times above-mentioned flue dust.Four water levels revolving cylinder by the automatic control of water gauge, and are constantly supplied water by supply-water pump, ensure the discharge of muddy water and supply new water.

Through four eddy flows, flue dust enters the unauspicious of this deduster, and unauspicious is eddy flow dehydrator, and flue gas is in this indoor rotation, and under the effect of centrifugal force, water flows to the outlet of bottom along barrel, by overflow water seal, arranges into sedimentation basin, cycling use of water.Gas is discharged by centre bore.
