Abstract

The utility model provides an efficient liquid-surface micro-division desulfurizing and dedusting device. The efficient liquid-surface micro-division desulfurizing and dedusting device comprises a tower body, wherein a demister, a spraying device and a module are sequentially arranged in the tower body from top to bottom, and a Venturi tube is also arranged at the bottom of the tower body. The efficient liquid-surface micro-division desulfurizing and dedusting device is mainly suitable for the desulfuration and dedusting of a small-size boiler and has the advantages of low cost, high efficiency and the integration of desulfuration, dedusting and demisting; as a micro-division mechanism is additionally arranged at the inner part of equipment, water resource can be utilized sufficiently and can be sufficiently subdivided and micro-divided among a plurality of layers of grids, so that superficial area is greatly increased, and the contact between liquid phase and gas phase is particularly sufficient; and desulfurizing and dedusting efficiency can reach higher than 98%.

Description

A kind of liquid surface differential high-efficient desulfation dust-extraction device
Technical field
The utility model relates to dustless application, is specifically related to a kind of liquid surface differential high-efficient desulfation dust-extraction device.
Background technology
Present sulfur dioxide of China and soot emissions total amount all up to more than 2,000 ten thousand tons, rank first in the world.Sulfur dioxide and smoke contamination have become the key factor of restriction China economy, social sustainable development.Desulfurization and dedusting technology comprises dust-collecting sulfur-removing method at present, the differential method, and venturi granite moisture film method is two, the alkali wet type, cloth-bag type, and limestone-gypsum wet method, the technical characteristic of each process of cleaning specifically sees the following form:
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of liquid surface differential high-efficient desulfation dust-extraction device.
The technical scheme that the utility model adopts: a kind of liquid surface differential high-efficient desulfation dust-extraction device, comprise tower body, be disposed with demister in the said tower body from top to bottom, spray equipment, module, the bottom of said tower body also is provided with Venturi tube.
As the further improvement of technique scheme, above-mentioned Venturi tube is a rectangle.
As the further improvement of technique scheme, said module is netted module.
As the further improvement of technique scheme, said module is a multilayer.
As the further improvement of technique scheme, said module is the differential module.
As the further improvement of technique scheme, said module is selected stainless steel or polymer composite for use.
As the further improvement of technique scheme, the said module aperture is the 10-30 order.
As the further improvement of technique scheme, said module thickness is 150-200mm.
As the further improvement of technique scheme, above-mentioned spray equipment is many groups.
Enforcement the utlity model has following advantage:
1, this device mainly is applicable to the medium small boiler desulfurization and dedusting, and it is with low cost, instant effect, with desulfurization in the dedusting demist in one, efficient is higher; Because device interior has added differential mechanism, can make full use of only water resource, and it can fully be segmented and differential between multi-layer net, surface area has increase, and the gas-liquid two-phase contact is abundant especially, and its desulfurization dust-removing efficiency reaches more than 98%.
2, the absorption solute in the absorption liquid is sheet alkali (NaOH), and absorption liquid can recycle for a long time, does not have the crystalline hydrate solute to separate out, and lye pump, pipeline, nozzle do not have clogging, need not safeguard.
3, combine venturi, wet type whirlwind, differential mechanism and spray etc., thereby realized the incorporate function of desulfurization and dedusting demist, operating cost and resistance are little, operate also easier.

Tower body 1; Demister 2; Spray equipment 3; Module 4; Venturi tube 5; Collapsible tube 501, trunnion 502, convergent divergent channel 503; Outer comb 6.
The specific embodiment
The liquid surface differential high-efficient desulfation dust-extraction device that the utility model provides comprises tower body 1, is disposed with demister 2 in the tower body 1 from top to bottom, organizes spray equipment 3 more, module 4, and the bottom of tower body 1 also is provided with the Venturi tube 5 of rectangle.Module 4 is netted, and is multilayer differential module, and its material adopts stainless steel or other metal materials to process, and also can use the polymer composite of resistant to elevated temperatures alkali resistance corrosion to replace, and it is shaped as cylindrical or elliposoidal or other shapes.Module 4 apertures are the 10-30 order, and whole module thickness is 150-200mm, and individual layer module thickness is 2-4mm, and each works as a layer module gap is 20-30mm, and whole module has the 6-10 layer approximately.
The operation principle of the utility model is following:
The sulfur-bearing ash-laden gas of discharging from boiler gets into by collapsible tube 501 along flue with the speed of 15-18m/s, and the rectangle Venturi tube of trunnion 502 and convergent divergent channel 503 can be transformed into kinetic energy with gas-static gradually through collapsible tube 501; Speed raises gradually, mixes at collapsible tube 501 terminal spray atomizing absorption liquids, and the speed that has arrived trunnion 502 position flue dust reaches 40-60m/s; Fluid is in stronger turbulence state, impels two of gas-liquids fully to mix, after the preliminary treatment; Behind convergent divergent channel 503,, after air inlet pipe 6 rotations, get into tower body 1 through the design of flowing backwards; Remove to clash into the netted module 4 of stainless steel multilayer, the module hole size is controlled between the 10-30 order, and multilayer module thickness is at 150-200mm; Individual layer module thickness is 2-4mm, and each individual layer module gap is 20-30mm, and whole module has the 6-10 layer approximately.Spray the absorption liquid that gets off from tower body 1 top when running into module 4, it can fully be segmented with differential between multi-layer net become little water curtain, liquid surface gathers increase.Improved the probability that flue gas contacts with absorption liquid greatly, flue dust is dispelling water curtain simultaneously, because the surface tension effects of liquid; Dust in the flue gas is abundant or dissolved absorption of sulfur dioxide and reaction by water and since flue gas in dust caught by water after, become nucleus; Impel water smoke sharply to condense and become drop; Under the flue gas that is rotated drives, do centrifugal motion, be thrown to inner wall of tower, discharge through outer comb 7 at the bottom of the inflow tower; This process is followed the absorption and the reaction of sulfide simultaneously, and efficient is up to more than 98%.After this flue gas continues to be handled step by step by vaporific spray liquid facility in uphill process, and the flue gas after multistage is handled is taken off most of moisture in the flue gas through demister, final row's mark.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
