Abstract
The utility model relates to a device for the smoke gas of coal boilers or other industrial dust, which simultaneously carries out smoke elimination, dust removing and desulfurization for harmful gas. In the utility model, a plurality of turboseparators are arranged in a tank body, a sprinkling pipe is arranged in each of the turboseparators, the upper part of the tank body is provided with a gas and liquid separator, an overflow tank is arranged on an ash collecting bucket, an overflow pipe is arranged on the overflow tank, and a flushing butterfly valve and a slurry discharging gate valve are arranged in an ash falling opening. Ideal smoke eliminating, dust removing and desulfurizing effects are obtained. The degree of Ringelmen blackness is less than one stage, the dust removing efficiency is more than 95%, and the desulfurizing efficiency is more than 90%. After being treated, the water can be used periodically.
Description
The utility model is the device that is widely used in various fire coal boiler fume smoke eliminations, dedusting, desulfurization.
In the flue of various coal-burned industrial boiler combustion systems, adopt the method for following several smoke eliminations, dedusting, desulfurization usually.
First kind, make first order cleaner by a kind of cyclone dust collectors, send into positive pressure handle flue gas by blower fan then and carry out desulfurization in the desulfurizing tower.Since two device processes are used in dedusting and desulfurization respectively, its cost of equipment height, and operating cost is big, takes up an area of now to amass greatly the SR height.
Second kind,, finish dedusting, desulfurization (as: Swashing type, water-bath type dust cleaner etc.) simultaneously by a wet scrubber.Owing to adopt periodic replacement to contain the alkali lye body, cause the desulfurized effect instability, the water level in this kind equipment flue-dust retainer is very big to dedusting and desulfurized effect influence, and resistance also produces great changes with the variation of water level.In addition, because that flue gas contact with alkali lye is insufficient, the time lacks, and dedusting, desulfuration efficiency are not high.
The third, spray in a kind of barrel type apparatus, wash, impact and make flue gas smoke elimination, dedusting, desulfurization, this type of equipment class is similar to the spray column in the chemical mechanical equipment, because the device space is very big, flue gas can not fully contact with alkali lye, and its dedusting and desulfuration efficiency are not high.
The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of compact conformation, smoke elimination efficiently, dedusting, desulphurization plant.
Can take following technology to realize purpose.This desulfurizing dust-collector is the device that a kind of smoke elimination, dedusting, desulfurization one are carried out simultaneously.Be made up of casing and flue-dust retainer two large divisions, arrange in the casing to be provided with a shower in each whirlwind by a plurality of whirlwind, casing top is provided with gas-liquid separation device.Flue-dust retainer is provided with spill box, and the bottom is provided with flushing butterfly valve and blowoff gate valve.Make smoke elimination, dedusting, the desulfurization product that to move continuously.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Accompanying drawing is that a kind of structure of desulfurizing dust-collector is shown and avoided figure.
This desulfurizing dust-collector is based on multi-tube dust cleaner.Adopt in parallel use of whirlwind (part 4) of a plurality of tangential admissions, casing and flue-dust retainer are separated by with dividing plate 3, and whirlwind is arranged on the dividing plate by different angles, pour into sub and guarantee sealing (seeing sealant 12) with fixing whirlwind then with alumina cement, aggregate.Sub-discharge pipe 5 of whirlwind and inclined clapboard 11 usefulness alumina cements, aggregate sealing and fixing (seeing sealant 10).Be provided with spray bend pipe 7 (shower) in whirlwind, its end and sweep have some apertures, can be to sub-import of whirlwind and discharge pipe import department ejection alkali lye.
The sub-ash port water-stop of whirlwind, (sealing range 20-100mm) guaranteed the efficiency of dust collection of whirlwind.
Owing to be provided with shower 7 in whirlwind, when flue gas enters casing by equipment importation 6, enter the whirlwind period of the day from 11 p.m. to 1 a.m with tangential direction, mix contacting at once with the alkali lye of shower ejection, flue gas along outer wall from top to bottom as spirality rotatablely move (outer vortex).Under action of centrifugal force, the grit and the globule are thrown on the outer wall, form a kind of moisture film on outer wall, and moisture film can be caught littler grit.The grit of arrival outer wall and water droplet fall into flue-dust retainer 2 along wall under the acting in conjunction of air-flow and gravity.Meanwhile produce neutralization reaction because the mixing of flue gas and alkali lye contacts, sulfur in smoke is fully absorbed.After the outer vortex of flue gas arrives cone base, then rotate up to the axle center, upper edge, mix with the alkali lye of shower 7 ejection once more when rotating to the import of discharge pipe 5, a part of water droplet is thrown on the discharge pipe inwall, because the gravity effect flows into whirlwind downwards along wall; Part water droplet is carried jointly by flue gas and upwards rotates, up to being discharged by discharge pipe.Because flue gas fully mixes once more, contacts with alkali lye in discharge pipe, the efficiency of dust collection of this equipment and desulfuration efficiency is greatly improved, efficiency of dust collection 95-98%, desulfuration efficiency 90-95%.After moisture flue gas was discharged by whirlwind, after gas-liquid separator 8 separated, pure gas was discharged by equipment outlet 9.
Desulfurizing dust-collector shown in the accompanying drawing is provided with spill box 13 to guarantee the water level in the flue-dust retainer on collection bucket 2.When water level changed within the specific limits, dedusting and desulfuration efficiency were unaffected.
In the desulfurizing dust-collector, flue-dust retainer bottom ash port 1 is provided with towards Xian's butterfly valve and ash discharge gate valve for slurry shown in the accompanying drawing.The ash discharge slurry can regularly discharge according to actual ash discharge amount, and the flow that also can regulate the ash discharge gate valve for slurry carries out continuous blowdown.
The relative prior art of the technical program has the following advantages and effect:
At first the utility model equipment adopts a plurality of showers to spray in each Whirlwind cyclone respectively Drench, flue gas and alkali lye are fully mixed, contact. Can be with the grit in the flue gas and SO2Gas Simultaneously in this equipment, carry out twice separation and absorption, can obtain desirable smoke elimination, dedusting, Desulfurized effect, lingemann blackness be less than 1 grade, dust removal efficiency＞95%, desulfurization degree＞90%, resistance Power is moderate. The plant area area is little, and is convenient by dress, has automatic adjusting water level, fixed Phase or continuous ash discharge slurry function. Water can be recycled after treatment, and product purpose is extensive, Both can be used for the purification of large, medium and small type Industrial Boiler flue gas, also can be used for other industry The purification of dust and pernicious gas. Rational in infrastructure, simple, convenient, use the longevity Life is long, and maintenance cost is low.
