Description

The smoke dust in boiler device

The utility model relates to a kind of smoke dust in boiler device, belongs to environmental protection equipment.

At present, the employed deduster of coal-burning boiler generally all adopts cyclone type, centicell unit, the deduster of this type is according to the dedusting of inertia reduction of speed principle, this dedusting method then can make it sink by the inertia reduction of speed for bigger soot dust granule, to reach the purpose of dedusting, tiny soot dust granule then is brought in the atmosphere with the wind, still causes to atmosphere smoke contamination to a certain degree, so efficiency of dust collection is lower.Pocket type, electrostatic precipitator efficiency of dust collection, effect are more satisfactory, but it costs an arm and a leg, and are difficult for promoting the use of at medium small boiler.Two types deduster in sum, its efficiency of dust collection height no matter, all ubiquity only has the shortcoming of single dedusting function, the sulfide that is contained in the flue gas for the boiler fired coal discharge and the gas of other oxious component, then can't handle at all, cause pernicious gas still to enter in the atmosphere and pollute.According to several overall target requirements of current environmental emission standard, the deduster of this single dedusting function is can not reach discharge standard far away.Give thus and use this type of to have the enterprise of single dedusting function deduster, on the environment protection standard problem, brought many worries.

The purpose of this utility model provides a kind of smoke dust in boiler device that can overcome above-mentioned technical deficiency part.

The purpose of this utility model is achieved in that the smoke dust in boiler device of forming by spray thrower, sprayer, deep bead, into and out of parts such as mouth and sewage draining exits, advance mouth and be installed in the one side bottom, outlet flue and sewage draining exit be lower end mounted thereto respectively, parts such as spray thrower, sprayer, deep bead are installed in its inside, spray thrower and the sprayer pipeline by separately respectively join with outside flange, clarifier advance mouth and employed boiler outlet flue joins; Outlet flue joins with the chimney air-introduced machine that is discharged; Sewage draining exit and circulating sedimentation tank join.During use, according to the sulfur content of fire coal, prepare the alkaline solution that is complementary with it, send in spray in the clarifier, the sprayer by circulating pump, make its spray, spraying.After the flue dust that need purify is admitted to clarifier, it is fully mixed with alkaline water smoke, come to increase fast the proportion of soot dust granule and the harmful components in the change flue dust thus, to reach the dual purpose of dust-removal and desulfurizing rapidly.

The utility model feeds the alkaline solution for preparing and sprays spraying because only need spray thrower, sprayer, deep bead are installed in the clarifier, can reach the double effects of dust-removal and desulfurizing, so structure is simple especially; Simultaneously, this utility model is easy to use, with low cost, reliable operation, applied widely, dust-removal and desulfurizing is satisfactory for result, test through reality: blackness of exhaustion is 0.5 grade of Lin Geman, and smoke dust discharge concentration is 93 milligrams/meter ³, pH value is 8-10 in the flue gas, and desulfuration efficiency is 84%, and combined dust-eliminating efficient is 92%, has reached discharging standards fully.And flue gas resistance need not to dispose in addition high-power air-introduced machine less than 40 millimeters of water.This utility model is present comparatively desirable environmental protection equipment, and extensive use can produce apparent in view society, economic benefit.

Figure of description 1 is a structural representation of the present utility model;

Figure of description 2 is the vertical view of the utility model spray thrower;

Figure of description 3 is a user mode schematic diagram of the present utility model.

The utility model is described in further detail in conjunction with implementing below with reference to Figure of description.

Smoke dust in boiler device of the present utility model, comprise clarifier (1), spray thrower (4), sprayer (5), deep bead (2), arc wind board (3), shower (10), injection spray pipe (9), advance mouth (6), outlet flue (12), sewage draining exit (8), the two ends up and down of clarifier (1) have outlet flue (12) respectively, sewage draining exit (8), clarifier (1) one side bottom has into mouth (6), deep bead (2) fixes by support (7) and clarifier (1) inwall bottom, sprayer (5) is installed on the deep bead (2), and join by injection spray pipe (9) and external flanges, spray thrower (4) is installed on the sprayer (5), and join by shower (10) and external flanges, spray thrower (4) top is equipped with deep bead (2), the upper space both sides of its deep bead (2) are respectively to there being the arc wind board (3) that fixes with clarifier (1) inwall, with outlet flue (12) bottom opposite position deep bead (2) is arranged, and fix by support (7) and clarifier (1) inwall top.Spray thrower (4) is that the cross pipe of two groups of horizontal directions is formed, its up and down two groups of cross pipes intersect 45 degree mutually and install, two groups of cross pipes communicate with the newel inner chamber, the horizontal direction of cross tube wall both sides have one with spray apertures.Sprayer (5) is a column tube, and more than one spray holes is arranged around its tube wall.

During fabrication and installation, earlier make clarifier (1), advance mouth (6) and be installed in the one side bottom according to the clarifying smoke needs of institute's use boiler, outlet flue (12) and sewage draining exit (8) are installed in its upper and lower end respectively, spray thrower (4), sprayer (5), deep bead parts such as (2) are installed in its inside, spray thrower (4) and sprayer (5) pipeline (10), (9) by separately respectively join with the flange of outside, and flow deflector (11) is installed in the outlet flue (12).The mouth (6) that advances of clarifier (1) joins by smoke-intake pipe (14) and boiler (13) outlet flue; The outlet flue (12) of clarifier (1) joins by smoke exhaust pipe (20) and air-introduced machine (21) import, and air-introduced machine (21) outlet is joined with chimney (22); The sewage draining exit (8) of clarifier (1) joins with circulating sedimentation tank (19); Spray, injection spray pipe (10) (9) join with control valve (16), (15) one ends respectively, join by circulation pipe (18) and circulating pump (17) after the other end of control valve (16), (15) is in parallel.

During use, according to coal-fired sulfur content, prepare the alkaline solution that is complementary with it and pour in the circulating sedimentation tank (19), make the circulation of its solution, regulate control valve (16), (15) work spray thrower (4) and sprayer (5) simultaneously by circulating pump (17).When the coal-fired flue dust of discharging of boiler (13) is in smoke-intake pipe (14) enters clarifier (1), flue dust rises under the effect of deep bead (2) and a large amount of alkaline water smoke of sprayer (5) ejection fully mixes, dust proportion in the flue dust increases fast at this moment, harmful components in the flue gas are changed rapidly, drop to sewage draining exit (8) after most of dust and harmful components are carried by alkaline water smoke, promptly finish purified treatment for the first time; Rising to spray thrower (4) through the flue dust after the single treatment locates, two-layer totally eight pipes on the spray thrower (4) are 45 degree each other mutually, every the pipe both sides horizontal direction all have one with spray apertures, this space of the whole covering of spray thrower (4) the two-layer jet of ejection, promptly wash the flue dust that rises once more, eliminate its smokeshade and harmful components.Substantially, become innocuous gas through the flue dust after above-mentioned twice purified treatment, forward enters smoke exhaust pipe (20) under flow deflector (11) effect, sends into chimney (22) by air-introduced machine (21) and is discharged in the atmosphere.The water that the dirt that is produced in decontamination process falls by spray, spraying at any time falls into sewage draining exit (8) and flows in the circulating sedimentation tank (19), and sewage filters through multi stage precipitation, still can continue to use.The technology that the utility model does not relate to all is a prior art, does not just give unnecessary details one by one here.
