Description
Technical field
The present invention relates to a kind of environmental protection facility, specifically a kind of facility of the harmful substances such as middle cigarette, dust, sulphur that remove smoke.
Background technology
Be the boiler, Industrial Stoves etc. of fuel with the coal, have the cheap relatively characteristics of fuel cost, but owing to behind the coal combustion, contain a large amount of ashes, co in the high-temperature flue gas of generation
2, harmful substance such as co, slag, the dense black smoke of release causes severe contamination to environment.Eliminate or reduce the method for smoke pollution at present, mainly contain two kinds: dry method or wet method, pluses and minuses separately are as shown in the table.
Summary of the invention
The objective of the invention is to, provide a kind of efficiency of dust collection high, simple in structure, maintenance, easy to maintenance, the facility that removes smoke and pollute of long service life.
The present invention has been achieved in that dust remover capable of eliminating smoke and desulphation and air-introduced machine.Dust remover capable of eliminating smoke and desulphation is being fixed a center axis body by spiral guide vane by dedusting wall, cylindrical cavity and place, inner chamber axis and is being formed.The gas approach place of cylindrical cavity is provided with sprayer unit.The middle and upper part of dedusting wall is provided with a plurality of dedusting water jets, and the bottom is provided with osculum; The front and back of dust remover capable of eliminating smoke and desulphation are connected with the downtake pipe road with the boiler smoke pipeline respectively; Air-introduced machine is installed on the downtake pipe road.Said air-introduced machine: be to make pernicious gas become the power of air-flow, generation impulsive force and the centrifugal force of high-speed motion.
Between dust remover capable of eliminating smoke and desulphation and air-introduced machine, can increase a desulfurizing tower, this desulfurizing tower is made up of the tower axle at Ta Bi, tower chamber and place, axis, tower chamber; Spiral fin is equipped with on tower axle top, and reverse acting spiral shape fin is arranged at the top; The middle and upper part of tower wall is provided with a plurality of sulphur removal water jets, and the bottom is provided with the tower osculum.The bottom of this desulfurizing tower communicates with dust remover capable of eliminating smoke and desulphation, and top and second exhaust pipe road join, and air-introduced machine is installed on the second exhaust pipe road.
Operation principle of the present invention is:
Dust remover capable of eliminating smoke and desulphation is made up of inlet plenum, clean room, dewatering station.
1, inlet plenum: ash-laden gas quickens in import throat collapsible tube gradually, and when arriving the throat place, flue gas flow rate is up to 25-35m/s, and flue gas is strong turbulent motion.Being provided with press water in the throat position sprays into---and be the vaporific whole throat that is covered with, the flue gas of high-speed motion, grit break through the mist film and the coacervating large particle ash globule.Then, get in the clean room of dust remover capable of eliminating smoke and desulphation.
2, clean room: be the centrifugal facility of machinery.Be provided with the multilayer deflector in this clean room, shower is equipped with on its top, and the bottom contains ponding.Ash-laden gas gets into from import department, in the shape of a spiral upset.In whole flow process, the grit in the flue gas receives mechanical action of centrifugal force to get rid of Xiang Tabi, rushes at deflector and bottom ponding place, takes the ash discharge groove of intracavity bottom after being adhered to by moisture film to, discharges automatically through the water seal ash discharging hole.
3, dewatering station: purified gas gets into dewatering station and reduces the rotation flow velocity suddenly, makes the moisture in the flue gas can not get enough centrifugal force and sedimentation, and the ash discharge groove of the moisture after the sedimentation at the bottom of tower discharged by the water seal ash discharging hole automatically.Separate thereby reach carbonated drink, make the flue gas after the processing not be with water.
The present invention's dust remover capable of eliminating smoke and desulphation with the harmful substance in the flue gas, reaches the purpose of eliminating its pollution through impact, bathing and mechanical centrifugal force.This dust remover capable of eliminating smoke and desulphation can use separately, also can use with the desulfurizing tower polyphone, and the reducing smoke and dust and desulfurizing effect when polyphone uses is better.The present invention is applicable to the auxiliary facility of all kinds of large, medium and small type boilers and Industrial Stoves, and to eliminating black smoke, the pollution of grey dust, sulfur dioxide has fairly obvious effect.Probationary certificate, this dust remover capable of eliminating smoke and desulphation meets the requirement of emission standard of air pollutants for boilers GB13271-2001 class one zone fully.Also reached the requirement among " Industrial Boiler and stove wet process of FGD engineering legislation " HJ462-2009 fully.
