Description
Technical field
The present invention relates to boiler fume desulfurizing and dedusting equipment, particularly the numb stone smoke desulfurization dust remover of combined type venturi and backwash water distribution.
Background technology
Fiber crops stone desulfurizing dust-collector develops into the secondary cylindrical tower granite duster of today through updating several times from gallet water curtain dust collector the earliest.I had once applied for a kind of numb stone smoke desulfurization dust remover device patent to State Patent Office, the patent No. is ZL200920140968.9, its principal character is: added the foam water bathroom and the second vertical impact chamber in the first vertical impact chamber that imports flue gas, the smoke dust duct that three Room communicate is a S shape, the exhanst gas outlet passage of the 3rd vertical impact chamber is provided with gas baffle, gas baffle and king-tower cylindrical are tangent, be provided with the liner post in the king-tower, the liner post is provided with plurality of sections cloth water column, be furnished with numb stone overflow basin and circular numb stone boss on the cloth water column, be provided with umbrella eddy flow plate between two numb stone boss of circle and the tower wall, on numb stone overflow basin, spray header is set, the foam water bathroom also is provided with spray header, first, the inclined plane is arranged in the sidewall in the second vertical impact chamber and foam water bathroom and the bottom of king-tower.Such numb stone desulfurizing dust-collector is compared with deduster in the past, has desulfurization and dedusting rate height, can consume lower by water consumption, stable equipment operation is reliable, and ash and slag disposal is characteristics easily, but still has the some shortcomings part, the inclined plane gradient that mainly is impulse chamber is slow excessively, ash deposition water seal tank floor space is excessive, heavy easily ash crust, and the deashing difficulty is big; The also heavy easily ash crust in bottom when overflow basin inherence is stopped using; Before flue gas entered secondary tower, it was also thorough inadequately to dewater.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, and the numb stone smoke desulfurization dust remover of a kind of combined type venturi and backwash water distribution is provided.This numb stone smoke desulfurization dust remover can not only solve lime-ash deposits crust and fan belt water in facility problem, and can improve desulfurization dust-removing efficiency, prolongs the service life of deduster, saves water resource, reduces operating cost.
The numb stone smoke desulfurization dust remover of combined type venturi of the present invention and backwash water distribution comprises that impulse chamber that flue gas imports and sprinkling equipment, ash deposition water seal tank, king-tower, secondary tower and the liner post that is provided with, cloth water column, circular numb stone boss, the umbrella in the impulse chamber execute the stream plate in king-tower, spray header, unlike the prior art be: the impulse chamber that flue gas imports is the combined type venturi, the inclined plane steepness of the sidewall of combined type venturi and the bottom of king-tower strengthens, and ash deposition water seal tank floor space is dwindled; Be provided with the tangential inlet control room, be communicated with the combined type venturi before the control room, the back is communicated with eddy flow plate king-tower, can impel flue gas to cut tower body inwall eddy flow and bang into tower body inwall moisture film, and dust in flue gas is sticked on the moisture film, further improves efficiency of dust collection; Sprinkling equipment in the king-tower has removed the overflow basin, changes backwash formula water distribution into, and boss is provided with the plane, and the water of spray header is sprayed onto that backwash comes out on the boss, trickles down on desulfurization eddy flow plate, and seam forms cascade in desulfurization eddy flow sheet separation; Eddy flow plate king-tower upper inside wall is provided with dehydration vertical partition plate bar, and steam is separated at many levels; The ash deposition water seal tank sidewall steepening of bottom, tangential inlet control room, the pond floor space is dwindled, and the ash that can not sink at the bottom of sidewall and the pond crusts.
Described combined type venturi is comprehensive granite with water film formula, the advantage of venturi type and three kinds of different modes of numb stone impact type comprehensively forms, sidewall has adopted rectangle swash plate contraction section, can not only stop the non-caked grey shell of interior walls, can make flue gas throw the roll-type water-bath again and wash efficient by rubbing with the hands in the moisture film face performance of swash plate, the two ends, chamber are horn mouth, the middle part is an aditus laryngis, aditus laryngis adopts the flat partially aditus laryngis of rectangle, under the situation of air-flow low-resistance, can performance catch droplet a dedusting and a desulfuration efficiency efficiently, also utilize flue gas to impact on the swash plate moisture film face simultaneously and the performance percussion, grey water throwing can be delivered in the king-tower and impel and do not deposit lime-ash.
Advantage of the present invention is:
1, makes full use of the operation that flue gas enters in the facility and be used to power, with the low-flow resistance with stop the in service of grey shell that bonds, controlling the physical reaction process of 13 levels of gas-liquid contact, impel the high efficiency unique performance of desulfurization and dedusting.
2, the water supply water distribution distributes suitablely to group to save water consumption, and eliminates thoroughly that water system is stopped up at any place and at body of wall face bonding honeycomb ash shell.
3, be in operation buck in the facility by the classification hang plate, the molten long-pending face of the water seal that reduces the scope is delivered in throwing simultaneously.And discharge with on foot sloping lowest part advection, made the stop leeway that lime-ash does not have deposition that removes in service.
4, the flue gas by wet-treating, in king-tower on sections adopt multi-level gas-water separation measure, flue gas enters thoroughly dehydration before the secondary tower.
5, this facility water supply water distribution is provided with special anti-blockingly, does not require pure water quality, suitable cycling use of water and use factory effluent, and cancellation is special-purpose consumes towards buck, can save water resource.
6, this desulfurization and dedusting facility all is numb stone (granite of natural sex), adopts modern advanced machine finish to be processed into parts, adopts high-intensity anti-corrosion material for building joint filler by laying bricks or stones, and is both attractive in appearance and durable in use.
7, this numb stone smoke desulfurization dust remover floor space is little, arranges not to be subjected to angle limits again (because the import of facility connects at the top, appointing to inserting resistance to equate).
8, this desulfurization and dedusting facility, operation is easy, does not need to open manhole and remove to clean dust stratification when inactive, and is then with normal water supply continual rinsing 10 minutes, neat and tidy in its facility, eliminated the sorrow of all hidden danger in the operation way.Undertaking straightway normal operation for enterprise and guaranteeing that economic benefit is not subjected to the influence of hidden trouble of equipment.
