Description

Water-filmed cyclonic dust collector
The utility model relates to Wet-way dust-collector, a kind of moisture film cyclone dust collectors.
Existing moisture film cyclone dust collector is a kind of double-cylinder type moisture film cyclone dust collector, is made up of urceolus, inner core, flue, water jet, outlet flue and discharge outlet.Flue gas enters the inner/outer tube space from flue, under the airflow effect, and eddy flow and descending, simultaneously, very fast combination of water smoke with water jet gets off owing to the centrifugal force that eddy flow produces, makes flue gas separate with dust in flue gas (impurity), the dust of separating, get rid of to barrel, adhered to, go downstream by moisture film, enter clarifier-tank from discharge outlet, and flue gas after being purified is discharged by the inner core dry type.But this mechanism, flue gas rotate downwards form so-called outside during eddy current, still have the fraction air-flow upwards and the obstacle that is subjected to top cover return again and formed last eddy current, this part air-flow is under the extruding of air-flow afterwards, directly downward punching press is not discharged by the exhaust inner core through purifying, thereby influence dust removing effects, the discharging flue gas after the dedusting still contains a certain amount of dust or harmful substance.
The purpose of this utility model is intended to the improvement to above-mentioned double-cylinder type water dust scrubber, adopts multistage dedusting method, provides a kind of efficiency of dust collection high moisture film cyclone dust collector.
That the utility model adopts is multistage (secondary or more than the secondary) dedusting method, promptly one-level is revolved separations, and the secondary free space separates, the three-stage filtration separation, will once intake and utilize for three times.Specifically, air-flow one advances to revolve, just with water smoke and the very fast combination of wall moisture film, under the effect of rotary centrifugal force, flue gas carries out the first order with dust in flue gas (impurity) to be separated, flue gas behind first class purification is by deflector freedom of entry space chamber, with cascade that from deflector overflow crack, flows down and the combination for the second time of deduster two wall moisture films, centrifugation, remove impurity, flue gas behind secondary purification carries out wet filter by the filter chamber, bottom again, and the Purge gas after the filtration is discharged from inner core and exhaust outlet.
Detailed technology content of the present utility model in conjunction with the embodiments and accompanying drawing further specified.
Fig. 1 is the front view of embodiment moisture film cyclone duster structure schematic diagram.
Fig. 2 is that the A of Fig. 1 moisture film cyclone dust collectors is to view.
Among the figure, (1) base, (2) control lock, (3) filter chamber, (4) inner core bearing, (5) free space chamber, (6) inner barrel, (7) outer cylinder body, (8) deflector, (9) interior outlet flue, (10) advance mouth, (11) hot water tap, (12) water jet, (13) loam cake, (14) outlet flue, (15) centrifuge dehumidifier, (16) rotation road upper cover plate, (17) rotation road, (18) blast pipe, (19) overflow crack.
Present embodiment by outer cylinder body (7), inner barrel (6), advance mouth (10), water jet (12), rotation road (17), deflector (8), filter chamber (3), drainpipe (18), outlet flue parts such as (14) is formed.Rotation road (17) is to be formed by the space that rotation road upper cover plate (16) and deflector (8) are comprised, and deflector (8) is pressed certain angle, the shape device in the shape of a spiral along the inner/outer tube space, and the oblique angle is preferably 15 °, and its effect is that flue gas of formation rotates the road.Overflow crack (19) is arranged on the deflector, make impurity and water after first class purification is handled flow into free space chamber (5) along the overflow crack, in free space chamber (5),, carry out second level purified treatment by the water combination that the flue gas that comes out of outlet flue (9) and overflow in the rotation road are got off.The effect of filter chamber (3) is that the micro-tiny floating dust that remains in the secondary purification gas is made third level purified treatment.Filter chamber (3) forms by a draining control valve (or lock) (2) is installed in the drainpipe (18), rely on control lock (2) to make the deduster bottom form certain water level, being used for filtration, purification handles, when water level arrives certain altitude, valve (or lock) (2) is opened under the hydraulic pressure effect automatically, allows water enter clarifier-tank.To purify requiring not really high deduster, can establish the filter chamber, promptly need not use control valve (or lock) (2), allow the water behind the secondary purification directly enter clarifier-tank by drainpipe.
During deduster work, flue gas sucks from advancing mouth (10), flow velocity is the 20-23 meter per second, in order to make the fine dust in the flue gas, the light-water floating dust, black smoke enters in the inner/outer tube body space after being soaked into by steam in the fastest time, be preferably in into mouth (10) and locate several hot water taps of device (11),, make the fine dust in the flue gas to flue gas spray hot water, rapid light-water floating dust, black smoke are subjected to entering after warm water vapour soaks into rotation road (17) in the fastest time.Flue gas is in the rotation road, the very fast combination of water smoke that same water jet (12) sprays and barrel moisture film, because action of centrifugal force, flue gas carries out the first order with dust to be separated, dust after the separation, get rid of to wall and adhered to by moisture film, the overflow crack by deflector flow to free space chamber, bottom (5).About deflector flue rotary speed 13 meter per seconds, when flue gas changed interior outlet flue (9) over to, because the relative aperture of interior outlet flue rotation road bore is little, at this moment, flue gas flow rate increased to the 18-20 meter per second, has increased the centrifugal force that is rotated down.From the flue gas that interior outlet flue (9) comes out, freedom of entry space chamber (5), the cascade that flows down with deflector overflow crack and the moisture film of barrel combine, and under centrifugal action, carry out second level flue dust and separate.Flue gas and impurity after the separation enter the filter chamber, and contamination precipitation is in the bottom, filter chamber, and flue gas carries out wet filter in the filter chamber, purify the minute quantity dust that remains in the flue gas.Suddenly go into the dry type inner barrel through the purification flue gas after the filter chamber filtration, because the anxious centrifugal force that turns round and produce of air-flow makes dust and water all be thrown toward inner tube wall with the rising of 5-6 meter per second speed, this process has evoked a large amount of sprays and bubble, and another has caught flue dust.Final purification gas slowly rises to centrifuge dehumidifier (15), and the Purge gas after the dehydration is discharged from outlet flue (14).Dust after deduster is handled enters clarifier-tank in company with filtered water from the drainpipe (18) of bottom.As seen, the utility model can revolve separation to the flue gas that contains dust (impurity), free space separates, multi-stage separation such as isolated by filtration, and can carry out three times to the water of water jet and utilize, promptly be used to revolve separation, free space separates (by the overflow crack of deflector), the filter chamber separates (as filtered water), combine wet type runway whirlwind, filter the dry type dehydration and separate the separation of the free whirlwind height of wet type centrifugal force and filter chamber, good dedusting effect, calculate according to subitems at different levels, efficiency of dust collection can reach more than 98%, every cube of flue gas water consumption 0.15-0.25 kilogram recirculated water.Cylinder material can adopt granite, plastics and acid resisting material.Present embodiment adopts the granite cylindrical shell, both is incubated, and anticorrosion is subjected to temperature, wind-force influence of fluctuations little again.The utility model is simple in structure, and cost is low, is a kind of comparatively ideal cleaner, is suitable for to make cleaners such as spreader stoker boiler, tempering furnace, coal-powder boiler, fluidized bed furnace.
