Description
Technical field
The utility model discloses a kind of flue-gas wet dust removal desulfurizer, belong to the flue gases purification field with waste heat recovery.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.In order to address the above problem, Chinese patent 200820110914.3 discloses 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.But the shortcoming of this patented technology is: the thermal loss in this devulcanizer is more, the heat in the boiler is not made full use of, the demand that discontented podomere can reduce discharging.
Summary of the invention
At the shortcoming that above-mentioned prior art situation exists, technical problem to be solved in the utility model provides a kind of flue-gas wet dust removal desulfurizer with waste heat recovery.It not only can make the flue-gas dust-removing and desulfurization that washed thoroughly purify, and has effectively solved the wearing and tearing and the blockage problem of spray head.And, the waste heat in the devulcanizer fully can be reclaimed and link to each other with water tank in the boiler, recycle, satisfy the requirement of energy-saving and emission-reduction.
The technical solution of the utility model realizes as follows:
A kind of flue-gas wet dust removal desulfurizer with waste heat recovery, it comprises that two ends are the circular body of cone.The upper end of circular body is the pure qi (oxygen) outlet, and the lower end of circular body is a gas approach, and the bottom perisporium of circular body is provided with the gap of control water level and the dirt-discherging outlet of dust discharge.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.Its design feature is that the periphery of the upper end of described circular body and pure qi (oxygen) outlet is provided with the preheating clear water tanks.Water inlet and delivery port are set on the preheating clear water tanks, between the upper end of the bottom of circular body and preheating clear water tanks many heat pipes are set.
In above-mentioned flue-gas wet dust removal desulfurizer, described many heat pipes are evenly arranged a circle along the inwall of preheating clear water tanks and circular body.
The utility model is owing to adopted above-mentioned structure, after liquid enters circular shower by water inlet pipe, flow down and form moisture film waterfall one time along the cone lining, after liquid flows to rain cap along the cone lining, flow down along the rain cap outer wall again and form secondary moisture film cylinder type waterfall.The gas approach that enters the utility model dust-removing desulfurizing device 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 utility model 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.When the bottom of this dust-removing desulfurizing device is arrived in the liquid following current, also remain suitable heat in the liquid.By set heat pipe the heat in the liquid is transferred in the set preheating clear water tanks and carries out heat exchange.In addition, the waste heat of pure qi (oxygen) outlet also can be preheated clear water tanks and absorb, and all reclaims with the waste heat of realization with this dust-removing desulfurizing device.Water in the preheating clear water tanks is connected with boiler water tank with delivery port by water inlet, recycles, and satisfies the requirement of energy-saving and emission-reduction fully.
