Description
Technical field
The utility model relates to a kind of dust arrester, relates generally to a kind of dust arrester of crop dryer.
Background technology
What the cleaner that existing drying machine drying plant is commonly used adopted is gravitational dust collection, because the particular principles of dryer requires to require that in drying course the source of air draft dust exhausting equipment is preferably clog-free, but is but far from it in the use of reality.Gravitational dust collection is that a kind of structure is simple, volume is large, resistance is little, inefficient more original cleaning equipment, can only be used for thick purification.But still containing a certain amount of minute dust in the waste gas of thick purification, though it is permitted cannot observe for naked eyes, larger to the ambient influnence (particularly more concentrated at city population) of surrounding, therefore the utility model increases water spray dirt pocket in the design.
Summary of the invention
(1) technical problem that will solve
The utility model with the addition of water spray dirt pocket, proposes water dust scrubber: be a kind ofly to utilize on dusty gas impact dust remover inwall or other special components with the moisture film that causes someway, dust caught by moisture film, the cleaning equipment that gas is purified.
(2) technical scheme
The utility model relates to a kind of dust arrester, relates generally to a kind of dust arrester of crop dryer.It mainly comprises gravity dust separator and water spray dirt pocket two large divisions, first gravity dust separator carries out a preliminary clearning to waste gas, still containing a certain amount of minute dust in the waste gas of preliminary clearning, though it is permitted cannot observe for naked eyes, but larger to the ambient influnence of surrounding, particularly in the city that population is comparatively concentrated.Therefore the utility model adds water spray dirt pocket, namely a water film dedusting in the design.Water film dedusting utilizes water source, by the special component that water pipe is equipped with---the moisture film that finer atomization shower nozzle causes, dust is caught by moisture film, and gas is purified, and the water of use then refluxes in sedimentation basin and recycles.
Further, described gravity dust separator mainly comprises ash bucket, filter bag, air-purifying chamber, relay, program control instrument, unloading valve, pulse spraying equipment composition, casing all adopts Welding Structure, and access door temperature resistant rubber bar sealing, ensures that deduster does not tightly leak out.
Further, waste gas enters filter bag by ash bucket, and now flow velocity reduces greatly, air velocity must not be greater than 3 meter per seconds, namely the grit that particle diameter is greater than 50 microns settles down under gravity and stays in filter bag surface, and preliminary clearning gas to air-purifying chamber, is blown into water spray dirt pocket by blower fan through sack.Be generally 10 ~ 20 millimeters of water by the pressure loss of filter bag, the efficiency of dust collection of gravitational precipitator is 40 ~ 60%, is applicable to dusty gas preliminary clearning.Dust in addition when filter bag surface constantly increases, when causing equipment resistance to rise to setting value, the time relay outputs signal, program control instrument is started working, one by one unbalanced pulse valve, makes compressed air carry out jetting deashing by spout to filter bag, under the effect of back draught, filter bag expands suddenly, and the dust investing bag table hightails filter bag and falls into ash bucket, and dust is discharged by unloading valve.After whole filter-bag blowing deashing terminates, deduster recovers normal work.
Further, described water spray dirt pocket mainly comprises cylindrical shell, lightweight ball float, nozzle, demister composition.Be screen below in cylindrical shell, screen placed the bead of some, there is nozzle layers of balls top spray after spray liquid atomization to bead surface, then there are again one deck bead and nozzle in top, is topmost dehydrator.General cylindrical shell is made up of carbon steel, inside lining anti-corrosive material, and anti-corrosion material can use anti-corrosion fiberglass; Also cylindrical shell outsourcing one deck fiberglass can be made with polypropylene.
Further, preliminary clearning gas is introduced along tangential by cylindrical shell bottom, rotates and rises, grit is separated by centrifugal action, throws to cylinder inboard wall, grit is contacted with liquid film, and be captured, grit and drop contact, thus increase weight and condense, adsorb by the water film that cylinder inboard wall flows, bottom cone is flow to water, draw off through dust-exhausting port, gas is evolved, the water of use then refluxes in sedimentation basin and recycles.
Further, the formation of described internal water rete is tangentially sprayed onto wall by the several nozzles being arranged in inner barrel by suitable for water.Like this, cover one deck all the time at cylinder inboard wall and rotate the very thin water film flowed downward, reach the object improving dust removing effects.
Further, described gravity dust separator is connected by pipeline with water spray dirt pocket, and preliminary clearning gas is directly blown into water spray dirt pocket by blower fan from gravity dust separator.
(3) beneficial effect
The utility model compared with prior art, it has following beneficial effect: water film dedusting utilizes water source, by the special component that water pipe is equipped with---and the moisture film that finer atomization shower nozzle causes, makes dust be caught by moisture film, gas is purified, and the water of use then refluxes in sedimentation basin and recycles.This utility model structure is simple, and easy to operate, efficiency of dust collection is high, and economize energy is reduced expenses, and reduces machine energy loss, and also has no effect to environment, expand the scope of application, also can use in the city that personnel relatively concentrate.
