The utility model discloses a design is unique, can realize completely that the exhaust emission who produces accords with national standard in the lime production process, pollution abatement, reduce cost, extension equipment life.
Description
Technical field
The utility model belongs to lime production field, particularly the desulfurization dust-removal system of limekiln flue dust.
Background technology
A large amount of waste gas and dust is produced in lime sintering procedure, from limekiln body flue-gas temperature about 120 DEG C out, dust content is at 120g/m3, containing sour gas, as SO2, CO2, the pernicious gases such as nitrogen oxide, need to carry out dedusting, degasification and desulfurization process, otherwise contaminated environment that will be serious, dusting and desulfuring system is in the past designed with defect, apparatus arrangement is unreasonable, accessing of dust, transhipments etc. are not easy to operate, need a large amount of manually to carry out operation, add processing cost and danger, dust pelletizing system does not reach environmental requirement, and device damage is serious, need often to carry out clearing up and keeping in repair.
Summary of the invention
Technical assignment of the present utility model provides a kind of Novel lime kiln flue gas desulfurization dust-removal system for above prior art deficiency.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel lime kiln flue gas desulfurization dust-removal system, comprise cyclone dust collectors, sack cleaner, air-introduced machine and desulphurization system, each wherein said equipment is connected by connecting pipe, in described cyclone dust collectors, flue gas enters along the inner tangential direction of deduster, granule dust is got rid of on wall under the influence of centrifugal force, particle falls to bottom collection along wall, cyclone dust collectors efficiency is high, equipment is little, SR is little, high power air-introduced machine can be joined, described sack cleaner top is provided with cloth bag group, bottom is provided with flue-dust retainer, described air-introduced machine is arranged between sack cleaner and desulphurization system.
Further, described desulphurization system is made up of desulfurizing tower, lye pump, circulating water pool and sealant supplement cylinder, desulfurizing tower internals adopt stainless steel corrosion-resistant, and inwall is lined with refractory brick, resist washing away of current, alkaline absorption solution in circulating water pool, through lye pump, water supply line, under Valve controlling, feed spray equipment at different levels in desulfurizing tower with suitable pressure and flow, react with the SO2 in flue gas, the SO2 in flue gas is removed.
The design of this utility model is unique, long service life, air-introduced machine is arranged in before desulfurizing tower, avoids desulfurizing tower demist insufficient, and the little liquid in flue gas is to the impact of fan blade, and topology layout is reasonable, reduce investment cost, automaticity height reduces the input of labour greatly, improves work situation simultaneously, dust and sour gas are effectively removed, reduces the dust pollution in place and the diffusion of bad smell.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Detailed description of the invention
With reference to Figure of description, the utility model is described in detail below:
As shown in Figure 1, a kind of Novel lime kiln flue gas desulfurization dust-removal system, draw together cyclone dust collectors 1, sack cleaner 3, air-introduced machine 5 and desulphurization system composition, each wherein said equipment is connected by connecting pipe, waste gas is introduced cyclone dust collectors through pipeline by kiln body top, flue gas tangentially enters cyclone dust collectors inside, under the influence of centrifugal force, big dust particle in flue gas is thrown on wall, under wall surface, slide to flue-dust retainer, the inward eddy that the flue gas be separated after bulky grain is formed centrally rising in deduster is expelled to the pipeline connecting sack cleaner through outlet.
The flue gas come from cyclone entrance enters sack cleaner 3 through pipeline, and described sack cleaner 3 top is provided with cloth bag group, and bottom is provided with flue-dust retainer 4.After flue gas enters casing, air-flow enters toilet through fine and close cloth bag group, discharge on deduster top, dust granules is then by cloth bag retentate surface, often at regular intervals, blowback system will to cloth bag blowback once, and cloth bag be expanded blowback by inverse flow of flue gas direction, the dust resting on cloth bag surface is blown down, and falls in the flue-dust retainer 4 of lower box.
Further, described air-introduced machine 5 arranges between sack cleaner and desulphurization system, described desulphurization system is made up of desulfurizing tower 6, lye pump 7, circulating water pool 8 and sealant supplement cylinder 9, flue gas from sack cleaner out after, enter in desulfurizing tower 6 through air-introduced machine, rotate with the flow velocity of feature, angle and direction and rise.The fogged lye counter current contacting sprayed with water-distributing device, the quality that gas, liquid, solid three are alternate and energy transferring significantly strengthen more than liquid unit expanded surface area to 200 doubly.Solid particle is atomized that water is moistening enters liquid phase.There is physical absorption and chemical reaction in the sulfur dioxide in gas phase, carbon dioxide etc., through repeatedly effectively absorbing, the acid ingredient in flue gas is removed between sour gas and alkali lye.The water droplet of wet flue gas after purification in vane demister interception flue gas, emptying through desulfurizing tower top chimney finally by the flue gas after demist.Alkaline absorption solution in circulating water pool, through lye pump 7, water supply line, under Valve controlling, feeds spray equipment at different levels in desulfurizing tower 6 with suitable pressure and flow.Waste liquid after desulfurization, the pipeline bottom desulfurizing tower is introduced circulating water pool and is followed 8 rings utilizations.
