Abstract

The utility model provides a dust collection, desulfurizing and waste water treatment facility of which the first stage dust collection can reach the state standard of effluent discharge, which has the advantages of little investment and low operation cost. The utility model is especially suitable for the waste gas treatment of which the discharge amount is below 10T/H in the coal-burning kilns in downtowns. A cyclone dust removal tower, a sloped tube settler and a slag storage pool are arranged in the solid way by the utility model. The land use is smaller than 30; the dust collection water can be reused; only a plurality of tons of water are supplemented each day.

Description

Wet dedusting and waste water disposal unit

The utility model is a kind of improved wet dust removal, the treating apparatus of the waste water of the secondary pollution of sulphur removal and generation thereof.Be particularly useful for the following coal-burning boiler of 10T/H and the exhaust-gas treatment of the stove in the urban district.It has solved big place and two many difficult problems of water that wet dedusting in the past needs.

The flue gas processing means of existing coal-fired furnace kiln mainly contain two kinds of dry method and wet methods.Dry method mainly contains: static, bag type filtering, cyclonic separation, sedimentation etc.Wet method mainly contains: cyclonic separation, filtration, sedimentation etc.The height of its efficient, investment and operating cost all is arranged in order and is static, bag type filtering, wet filter, wet type cyclonic separation, dry type cyclonic separation, sedimentation.But the whole bag of tricks all is subjected to condition restriction separately, being tied minimum is the cyclonic separation method, but one-level dry type cyclonic separation does not reach discharging standards, one-level wet type cyclonic separation then can reach discharge standard: investment and operating cost are most economical, and effect is reasonable again to be wet type whirlwind partition method; In high-effective dust-removing, again can sulphur removal be wet type whirlwind partition method.But often because: few these two problems in lack of water and place, urban district have influenced applying of wet type whirlwind process of cleaning.

The utility model is exactly the device of wet type whirlwind partition method that has solved two difficult problems in above-mentioned lack of water, few place.It has kept reduced investment, operating cost is low, efficient is high advantage, and management is simple, water saving, province place, non-secondary pollution.

The utility model is reached by following manner:

With main facility cyclone dust removal tower, sedimentation basin, three layers of layout of the vertical branch of storage slag bath.The cyclone dust removal tower is put the highest, and water seal is not done by the water logging of tube settler in the bottom of tower, and the bottom of sedimentation basin is the storage slag bath, its storage slag and filtration.

Be described in detail as follows in conjunction with the accompanying drawings:

The stove flue gas is gone into from cyclone dust removal tower A air inlet tangent line 1., and grit is subjected to centrifugal action, contacts with the moisture film of tower wall, by water towards the tube settler at the bottom of tower 3..Waste gas is through separating grit and 2. being discharged by the B place after the spray washing purification by shower nozzle.The waste water that 3. tube settler will contain grit carries out Separation of Solid and Liquid, and grit is deposited in the taper bucket at the bottom of the pond, and clear water then spills into the gutter of pond body around the top, concentrates the back 4. to draw back 1. reuse of gas wash tower by pump, additional fresh water and alkaline water at C place.Grit deposits to a certain degree, 5. just opens slag slurry drain valve 6. by the electromagnet of time relay control, and the slag slurry is after the short time discharging, and 5. electromagnet does not work, and 6. 7. balance weight cut out residual cake valve.Slag slurry be discharged into the storage slag bath 10. after, 9. filter through packing layer, clear water from the gutter (11) drain, 8. slag is stayed the storage slag bath and is waited to transport.

The dedusting of a 10T/H boiler, sulphur removal and the about 20m of waste water disposal facility land used thereof ²But, because waste water reuse after treatment, so every day is as long as replenish several tons of water.

Claims

1, one by the cyclone dust removal tower 1., tube settler 3., the residual cake valve 5. controlled of electromagnet 6., the dedusting 10. formed of storage slag bath, sulphur removal and waste water disposal facility thereof is characterized in that:

A, entire process facility are three-dimensional the layouts, the cyclone dust removal tower 1. be located at tube settler 3. on, and tube settler 3. be located at the storage slag bath 10. on.

5. 6. b, residual cake valve control the unlatching deslagging by electromagnet, 7. close residual cake valve 6. by balance weight at ordinary times.

10. c, storage slag bath itself are filtering ponds, and the maximum layer filtrate is exactly a slag itself.
