Abstract
The invention relates to a flue-gas wet dust removal desulfurizer which belongs to the technical field of flue-gas purification. The flue-gas wet dust removal desulfurizer comprises a circular device body, a purified gas outlet and a flue-gas inlet and is characterized in that a circular tube of the flue-gas inlet extends into the circular device body, a rain cap is arranged at the top of the circular device body, a cone bushing is arranged above the rain cap, and a circular spraying tube is arranged above the cone bushing. When water is sprayed onto the cone bushing from the circular spraying tube and flows onto the rain cap from the peripheral wall of the cone bushing, a secondary water-film waterfall on the internal wall surface of the cone bushing and the outer wall surface of the water cap is formed. In the gas wet dust removal desulfurizer, not only the flue gas can generate a plurality of collision choices with water in the device body, but also the flue gas rinsing effect and the desulphurization effect of the water-film waterfall are greatly improved, the abrasion and the blockage of a spray header are effectively solved, the ascending resistance of the flue gas is reduced simultaneously, and the manufacturing, installing and operating cost is greatly reduced. The invention has the advantages of reasonable design, simple structure, low cost and wide application and usage value.
Description
Technical field
The invention discloses a kind of flue-gas wet dust removal desulfurizer, belong to the flue gases purification field.Be to the dust of boiler export flue gas and the integration apparatus of sulfur dioxide dust-removal and desulfurizing.
Background technology
Flue gas ash removal is two importances that control environment and pollute with removing sulfur dioxide.Wet dedusting desulfurization principle of the prior art: after generally adopting boiler smoke to enter deduster, by shower water the time, swash, adopt the physics method to make water atomization washing flue dust with water.In addition, shower water can use alkaline solution, adopts the chemical method reacting generating salt in sulfur in smoke and a spot of sulfur trioxide and the alkaline solution contact process, and ash-pit falls bottom dust falls into deduster.Through post precipitation, through artificial or grey machine ash is gone out clearly from ashpit again.Flue gas after being purified is aspirated naturally through chimney and is discharged to atmosphere.There is following shortcoming in the prior art equipment that adopts this common principle to make at present: 1, general flue gas only once contacts the chance that swashs mutually with shower water, causes the washing flue dust abundant inadequately; 2, shower water generally adopts the spray head injection that special nozzle is made, and not only costs an arm and a leg, and very easily produces wearing and tearing and obstruction.
Summary of the invention
Shortcoming at above-mentioned prior art situation existence, technical problem to be solved by this invention provides a kind of flue-gas wet dust removal desulfurizer, it not only can make flue gas produce repeatedly the chance that swashs with water in body, flue gas must be washed through twice moisture film waterfall, the flue-gas dust-removing and desulfurization that washed is thoroughly purified, and effect improves greatly.And wearing and tearing and the blockage problem that can effectively separate spray head, and can reduce manufacturing cost greatly.
Technical scheme of the present invention realizes as follows:
A kind of flue-gas wet dust removal desulfurizer, it comprises that two ends are the circular body of cone.The upper end of circular body is the pure qi (oxygen) outlet.The lower end of circular body is a gas approach.The bottom perisporium of circular body is provided with the gap of control water level and the dirt-discherging outlet of dust discharge.Its design feature is that the pipe of described gas approach extends in the circular body.The pipe top of gas approach is provided with the rain cap that is connected by stent support, the top of rain cap is provided with the cone lining that is connected with circular body inwall, the top of cone lining is provided with the circular shower around circular body inwall, and the external water inlet pipe of circular shower and circular device is connected.Offer many uniform perforates on the tube wall below the circular shower radius.When water when each perforate of circular shower is sprayed onto on the cone lining and flow on the rain cap by cone lining perisporium, form the secondary water waterfall of cone lining internal face and rain cap outside wall surface.
The present invention has been owing to adopted above-mentioned structure, flows down along the cone lining after liquid enters circular shower by water inlet pipe and forms moisture film waterfall one time, after liquid flows to rain cap along the cone lining, flows down formation secondary moisture film cylinder type waterfall along the rain cap outer wall again.The gas approach that enters dust-removing desulfurizing device of the present invention from the flue gas of boiler output enters in the circular body, because the prevention of rain cap makes flue gas wear to prolong from moisture film waterfall between the bottom of rain cap and the gas approach and upwards obtains once the chance that swashs mutually with the liquid contact, owing to the suction force effect of pure qi (oxygen) outlet, mixed flue gas upwards contacts once more mutually with cone lining inwall water waterfall again and swashs again.Institute is so that water atomization washing flue dust and desulfurized effect improve greatly.In addition, the used spray head of the present invention is the circular shower of many uniform perforates of offering on the following tube wall of its radius, need not to use expensive special nozzle, the wearing and tearing and the blockage problem of spray head had both been solved, flue gas rising resistance is reduced, do not need to increase the air inducing power-equipment, greatly reduce again and make the installation and operation cost.The present invention is reasonable in design, and is simple in structure, and cost is low, has the value of extensively promoting the use of.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cross section view.
The specific embodiment
Dust-removing desulfurizing device of the present invention comprises that two ends are the circular body 2 of cone.The upper end of circular body 2 is pure qi (oxygen) outlet 1, and the lower end of circular body 2 is a gas approach 9, and the bottom perisporium of circular body 2 is provided with the gap 7 of control water level and the dirt-discherging outlet 8 of dust discharge.The pipe of gas approach 9 extends on the waterline in the circular body 2.The pipe top of gas approach 9 is provided with the rain cap 5 by support 6 support and connection, and the top of rain cap 5 is provided with the cone lining 4 that is connected with circular body 2 inwalls, and the top of cone lining 4 is provided with the circular shower 3 around circular body 2 inwalls.Circular shower 3 is connected with circular body 2 water inlet pipe 10 outward, offers many uniform perforate 3-1 on the tube wall below circular shower 3 radiuses.When water when each perforate 3-1 of circular shower 3 is sprayed onto on the cone lining 4 and flow on the rain cap 5 by cone lining 4 perisporiums, form the secondary moisture film waterfall of cone lining 4 internal faces and rain cap 5 outside wall surface.
Using method of the present invention is same as the prior art, and the shower water that is injected in the circular shower 3 by water pump generally uses alkaline solution.Sulfur in smoke and a spot of sulfur trioxide are swashing reacting generating salt in the process mutually with the contact of the secondary of alkaline solution, fall into the bottom of circular body 2 with dust, enter sedimentation basin through dirt-discherging outlet 8.Through post precipitation, by artificial or ash hoist ash is gone out clearly from ashpit again.Flue gas after being purified is aspirated discharge from pure qi (oxygen) outlet 1 naturally by chimney.The alkaline solution that flows out by gap 7 and can recycle repeatedly by liquor box and water pump through the alkaline solution of post precipitation.
