Description

Big flux high-efficiency cyclone plate tower desulfurizing and dust removing unit
Technical field
The utility model belongs to environmental protection and resource technical field, relates to a kind of desulfation dust-extraction device of prevention and control of air pollution.
Background technology
Dust arrester commonly used has mechanical collector, wet scrubber, filtration dust catcher and electric cleaner.The wet scrubber of imitating during water film dust removal device belongs to, main structure comprises cylindrical shell, spray equipment, demister etc., and efficiency of dust collection is 85-90%, and desulfuration efficiency only is 10-15%.Along with people to improving constantly that atmosphere quality requires, the control of sulfur dioxide is required also progressively to improve.At present, general on the basis of original dust arrester in order to control the discharge capacity of sulfur dioxide, add desulfurizer again thereafter, to reach the target of desulfurization and dedusting.
Though this technical method can reach the purpose of desulfurization and dedusting, newly-built absorption tower has increased floor space in order to desulfurization, is not suitable for the smaller situation in place, and must increase investment and operating cost.
The utility model patent of patent No. ZL98243156.2 discloses a kind of high-efficient desulfation dust-extraction device, this device includes a venturi water film dust arrester, also has a concentric circles water mist desulfurized dust collector, in the middle of this device is smoke-intake pipe, outer periphery several layers concentric drums, the top is provided with water injector, have smoke uptake at smoke-intake pipe and each layer concentric drums, the outlet flue of concentric drums is connected with the inlet flue duct of venturi water film dust arrester by a middle flue, is provided with the hydrolock overflow mechanism in the bottom of concentric circles water mist desulfurized dust collector.But its flux is little, thereby barrel diameter is big, and floor space is big, and having relatively high expectations to basic load-bearing.
The utility model patent of patent No. ZL01263901.X discloses a kind of whirlwind water film type desulfurizing dust-collector, and it comprises all parts such as desulfurization dust separation chamber, indoor spray head settling tank, administration liquid device, centrifuge dehumidifier.Bottom, desulfurization dust separation chamber is provided with spiral scroll casing shape smoke-intake pipe, it advances mouth and connects boiler boiler exhaust gas road, its outlet flue communicates with the desulfurization dust separation chamber, the above clean room's microbody inwall of spiral case smoke-intake pipe is welded with the polylith spiral deflector, spiral deflector is above to be fixed with the water film dedusting net near clean room's tube inwall, seedpod of the lotus shape shower nozzle has the nozzle of a plurality of sensing oblique uppers in the clean room, and the clean room establishes centrifuge dehumidifier in the top, and the clean room establishes primary sedimentation basin in the bottom.But its inner barrel complex structure, nozzle and filter screen all stop up easily.
Summary of the invention
The utility model provides a kind of big flux high-efficiency cyclone plate tower desulfurizing and dust removing unit, and water film dust removal device and desulfation dust-extraction device is integrated, improves desulfuration efficiency greatly, and further obviously improves efficiency of dust collection.
The technical method that the utility model rotating stream tray scrubber desulfation dust-extraction device is adopted is:
A kind of big flux high-efficiency cyclone plate tower desulfurizing and dust removing unit comprises water dust scrubber, and the inner barrel of water dust scrubber adds the multi-layer rotational flow column plate, rotating stream tray by blind plate, be close to the swirl vane of blind plate and fixedly the ring support of swirl vane form.
Described ring support is provided with several liquid-leaking nozzles, and the liquid-leaking nozzle below is connected with the downspout of inclination.
The ratio of interval area between the described swirl vane and cylindrical shell sectional area is 20-50%.
The swirl vane quantity of described rotating stream tray is the 8-200 sheet, and the anglec of rotation of swirl vane and horizontal plane is 15-50 °.
The utility model device can be used for various desulfurization dust-removing techniques such as two alkaline process, lime/lime stone method, alkaline waste method.
Generally, the empty tower gas velocity of common rotating stream tray scrubber is 2.5-3m/s, and adopts the empty tower gas velocity through improved rotating stream tray of the present utility model can be up to 3.1-6m/s.Gap between the swirl vane of rotating stream tray scrubber of the present utility model is bigger, and the ratio of interval area and cylindrical shell sectional area is up to 20-50%, thereby the assurance low pressure drop prevents that simultaneously column plate from stopping up; Adopt suitable swirl vane angle (15-50 °), guarantee the fully effect of atomizing, can make mist droplet granularity reach tens microns (common rotating stream tray scrubber droplet reaches the hundreds of micron), thereby guarantee high desulfurization dust-removing efficiency; Efficiency of dust collection of the present utility model can reach more than 99.8%, and desulfuration efficiency can reach 70-99%, and the pressure drop that increases (or claiming resistance drop) only is 500-1000Pa.
The utility model also can be used for transforming original water film dust removal device, need not increase and build desulfuration absorbing tower, not change water dust scrubber cylindrical shell, ventilating fan not, not increase floor space, only in tower, add rotating stream tray to increase the gas-liquid contact area, improve desulfurization dust-removing efficiency.The device internal structure is simple, less scaling, and investment for trnasforming urban land is little, and operating cost is low.
