Description
Technical field
The utility model relates to the rich sulfur mineral flue gas desulfurization device of burning field, is specifically related to a kind of device that the gas that is rich in sulfur dioxide is washed.
Background technology
In traditional ammonia desulfurizing process, adopting before the absorption liquid absorbing sulfur dioxide, generally need be to coal or oil being SO in a large amount of flue gases of coal-burning boiler or thermal power plant discharging of fuel
X, and little amount of N O
X, harmful substance such as HCl removes, water scrubber is modal device.But; When traditional water scrubber contacts with the very high flue gas of temperature; Particularly when high concentration sulfur dioxide gas that rich sulfur mineral such as burning sulphur etc. produces contacts, still contain a large amount of sulfur dioxide gas in the rinsing solution, if these sulfur dioxide gas can not be released; Continue to be trapped in the circulation fluid, water washing effect will be had a greatly reduced quality.
The utility model content
The purpose of the utility model is: the device that provides a kind of high concentration sulfur dioxide gas that rich sulfur minerals such as burning sulphur are produced to wash, and fully with the sulfur dioxide recovery in the recirculated water.
The technical scheme that the utility model adopts is: a kind of device that the gas that is rich in sulfur dioxide is washed comprises water scrubber, degassing tower, slag liquid accumulator tank, circulating pump, mashing pump.The bottom of said water scrubber is provided with gas approach, and the top is provided with exhanst gas outlet, and the bottom is provided with the water scrubber kerve, and water scrubber inside also is provided with shower, and shower is provided with some shower nozzles, and shower links to each other with slag liquid accumulator tank with mashing pump by the road; Be provided with the circulation fluid outlet at the water scrubber kerve, the circulation fluid outlet links to each other with the circulation fluid import of mashing pump and degassing tower by the road.Said degassing tower top is provided with the circulation fluid import, and the top is provided with gas vent, and the bottom is provided with the degassing tower kerve, and the degassing tower kerve links to each other with slag liquid accumulator tank by the road.
Further, the pipeline between degassing tower kerve and the slag liquid accumulator tank is provided with valve.The preferred 2-3 of quantity of said shower (9).
Be transported in the shower nozzle from inlet through the water of circulating pump slag liquid accumulator tank; After the circulation fluid that forms after rich sulphur gas contacts with water falls into the water scrubber kerve; Circulation fluid in mashing pump water scrubber kerve is transported to the circulation fluid import; Circulation fluid cools off in degassing tower, outgases, and gas flows into slag liquid accumulator tank after breaking away from completion, and the top is provided with gas vent.After the gas of discharging draws the gas of discharging with water scrubber and converges, can use for next step desulfurization.
The beneficial effect of the utility model is that employing water can separate rich sulphur IMPURITIES IN as circulation fluid with flue gas; The circulation fluid of the high temperature that warp is contacted with flue gas cools off in desulfurizing tower, wherein remaining sulfur dioxide gas is collected, and converged with sulfur dioxide gas that water scrubber is discharged; The circulation fluid that will pass through the degassing tower degassing flows into slag liquid accumulator tank, realizes that the solid impurity in the slag liquid accumulator tank reclaims.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1-water scrubber; The 2-degassing tower; 3-slag liquid accumulator tank; The 4-gas approach; The 5-exhanst gas outlet; The import of 6-circulation fluid; The 7-gas vent; The 8-shower nozzle; The 9-shower; The 10-circulating pump; The 11-valve; 12-degassing tower kerve; The 13-mashing pump; 14-water scrubber kerve; The outlet of 15-circulation fluid.
The specific embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further.
As shown in Figure 1, a kind of device that the gas that is rich in sulfur dioxide is washed comprises water scrubber 1, degassing tower 2, slag liquid accumulator tank 3, circulating pump 10, mashing pump 13.The bottom of water scrubber 1 is provided with gas approach 4; The top is provided with exhanst gas outlet 5, and the bottom is provided with water scrubber kerve 14, and water scrubber 1 inside also is provided with 3 showers 9 from top to bottom; Shower is provided with 6 shower nozzles 8, and shower 9 links to each other with slag liquid accumulator tank 3 with mashing pump 13 by the road; Be provided with circulation fluid outlet 15 at water scrubber kerve 14, circulation fluid outlet 15 links to each other with the circulation fluid import 6 of mashing pump 13 and degassing tower by the road.Degassing tower 2 tops are provided with circulation fluid import 6, and the top is provided with gas vent 7, and the bottom is provided with degassing tower kerve 12, and degassing tower kerve 12 links to each other with slag liquid accumulator tank 3 by the road.Pipeline between degassing tower kerve 12 and the slag liquid accumulator tank 3 is provided with valve 11.The gas vent 7 at degassing tower 2 tops is connected through the discharge line of pipeline with the exhanst gas outlet 5 at the top of water scrubber 1.
