Abstract
The main structure of a desulfuration and dedusting device is characterized in that the smoke enters into a heat exchanger, and the temperature of the gas containing sulfur dioxide discharged from a combustion boiler is reduced by the smoke. Then after the dedusting of a cleaning box is conducted and the smoke is filtered by water, the gas can be directly discharged into the air. The liquid in the cleaning box is desulfurated after inflowing into a desulfurizing tower and the liquid can directly inflow into the cleaning box after the desulfuration and can be used circularly. The structure of the desulfuration and dedusting device has the advantages of being simple in technology, low in cost and easy to popularize.
Description
Affiliated technical field
The utility model relates to the structure field, especially a kind of structure that aims at the desulfurating dust-removing equipment of fire coal boiler fume and design.
Background technology
At present, the coal-burning boiler of China's majority still adopts traditional granite water film dust, dedusting and the desulfuration efficiency of this granite water film dust are lower, be difficult to reach the boiler smoke discharge standard of Environmental Protection in China department defined, and complex structure, investment is large, operating cost is higher and difficult universal shortcoming.
The utility model content
Existing desulfurating dust-removing equipment complex structure, investment are large in order to overcome, operating cost high being difficult for popularize, and the utility model provides the structure of a desulfurating dust-removing equipment, and this equipment is not only simple in structure, and desulfurized effect is good, with low cost and easily popularize.
The utility model solves the technical scheme that its structure problem adopts: the part such as the dust cleaning case in the desulfurating dust-removing equipment structure, sedimentation basin, desulfurizing tower, recovery tower is by pipeline circulation UNICOM.At first flue gas connects heat exchanger, and the temperature that coal-burning boiler is discharged still high sulfur-bearing dust-laden exhaust gas is lowered the temperature by heat exchanger, then passes into the dust cleaning case dust-removing sulphur removing function again.
Dust cleaning case is the thin wall cylindrical bucket of an accumbency, is provided with the helical form guide vane in the bucket, and the middle and upper part of blade is fixed with close the touching of bucket wall, and there is certain spacing its underpart with the bucket wall, injects a certain amount of water in bucket.
When the dust in the boiler waste gas was cleaned by water, sulfur dioxide wherein was water-soluble, generation sulfurous acid, will be cleaned rear free of contamination waste gas and enter atmosphere.
Sedimentation basin is set.The sulfurous acid solution that will contain solid dust passes into sedimentation basin and removes the comparatively limpid liquid of dust one-tenth and pass into desulfurizing tower.
Fill block lime stone in the desulfurizing tower.Sulfurous acid and lime stone reaction generate gypsum etc., thereby sulphur is sloughed from water again, and the water that contains gypsum is passed into recovery tower, and the lower gypsum of precipitation becomes comparatively clear water, feeds back into dust cleaning case through Micropump, forms a circulation.
The beneficial effects of the utility model are: the simple in structure, with low cost, easy of this desulfurating dust-removing equipment popularized, and desulfurization and dedusting is effective.
Description of drawings
Below in conjunction with accompanying drawing and enforcement the utility model is further described.
Accompanying drawing 1 is the perspective view of desulfurating dust-removing equipment structure
1. boilers, 2. pipes, 3. heat exchangers, 4. blower fans, 5. dust cleaning cases, 6. chimneys, 7. pipelines, 8. precipitations among Fig. 1
The specific embodiment
Such as figure, the temperature of discharging from boiler (1) still high sulfur-bearing dust-laden exhaust gas enters heat exchanger (3) through pipe (2), cool to about 50 ℃ through blower fan (4) and be blown into the end from dust cleaning case (5) of speed faster, enter chimney (6) discharging after being cleaned.Purpose to the waste gas cooling is to be conducive to SO wherein

Heat exchanger (3) is to utilize natural air to lower the temperature for high-temp waste gas, is inhaled into boiler (1) after natural air is heated up combustion-supporting, thereby can fuel savings.
Dust cleaning case (5) is the thin-wall circular tubular of accumbency.In establish the helical form guide vane, upper along touching with the bucket wall is close in the blade, its lower along with the bucket wall at a distance of suitable distance, the water of built-in certain depth.The sulfur-bearing dust-laden exhaust gas corkscrews under the water conservancy diversion of blade and repeatedly impacts the water surface, can make dirt and SO
2Incorporate in the water fully, thereby reach the effect of cleaning waste gas.
Dust-laden, sulfur-containing waste water are through the bottom input of pipeline (7) from sedimentation basin (8), through precipitation, the comparatively limpid sulfurous acid waste water of one-tenth.
Sulfurous acid waste water flows into the bottom outflow from the top of desulfurizing tower (9).Fill desulfurizing agent in the tower---block lime stone CaCO

Contain gypsum waste water and be passed to recovery tower (11) through Micropump (10), become comparatively the clear water circulation through precipitation and reenter dust cleaning case (5) and finish a circulation.
Claims (2)
1. the structure of a desulfurating dust-removing equipment is characterized in that: dust cleaning case, sedimentation basin, desulfurizing tower, recovery tower are by the pipeline UNICOM of circulating.
2. the structure of desulfurating dust-removing equipment according to claim 1, it is characterized in that: dust cleaning case (5) is the barrel-shaped of accumbency, in establish the helical form guide vane.
