Abstract
The utility model relates to a high-speed inner cross current absorption tower having a T-shaped structure. The lower part is a cylindrical or elliptical circulating slurry pond, and the upper part is a horizontal flue of a spraying absorption zone; an air oxidation pipe and a side stirrer are distributed in the circulating slurry pond, and two or three layers of spraying devices are distributed in the spraying absorption zone; and circulating slurry can be conveyed into the spraying devices from the circulating slurry pond. The spraying absorption zone is arranged in the horizontal flue above the circulating slurry pond, and the circulating slurry sprayed upwards and downwards in the spraying absorption zone is in cross current type contact with flue gas flowing horizontally. The utility model has the advantages of simple structure, small volume and occupied space, and lower cost, thereby facilitating improvements on the system operation efficiency and the desulfurization efficiency.
Description
One, technical field
The utility model belongs to industrial waste gas purifying environmental protection and energy field, particularly is used for the interior cross-flow absorption tower of high speed of gas cleaning.
Two, background technology
Flue gas desulfurization is SO in the control coal-fired flue-gas that extensively adopts both at home and abroad at present
2Effective ways, wherein wet fuel gas desulfurizing technology be use on the our times at most, the most effective flue gas desulfurization technique.The absorption tower of being adopted in the wet fuel gas desulfurizing technology is adverse current void tower structure mostly at present, the absorption tower is followed successively by circulation stock tank, gas approach, spraying layer, mechanical demister and exhanst gas outlet from bottom to up, the absorption tower tower body height of the type, floor space is big, flue gas resistance is big, limited the desulfurization transformation of existing boiler unit greatly, and some semi-dry desulfurizing process do not reach SO
2Allow the concentration of emission limit value with flue dust.
Three, utility model content
The purpose of this utility model is to provide a kind of housing structure that is applicable to wet process of FGD, also is applicable to the desulfurization transformation of old unit.
The utility model is realized in the following way:
Cross-flow absorption tower at a high speed, comprise recycle slurry liquid pool, horizontal flue, spray equipment, this absorption tower is a T type structure, the bottom is column type or disciform recycle slurry liquid pool, top is the horizontal flue of spray uptake zone, spray is furnished with two-layer or three layers of spray equipment in the uptake zone, and spray equipment connects the recycle slurry liquid pool by slush pump and pipeline.Be furnished with oxidation air pipe and agitating device in the circulation stock tank.The import of spray uptake zone is connected with clean flue gas flue with former flue gas flue respectively with outlet, the flue gas that boiler is discharged carries out desulfurization in spray uptake zone, absorption tower, after the demister in the horizontal flue of the flue gas after the desulfurization after being arranged in the absorption tower outlet carries out demist by smoke stack emission.The horizontal flue bottom of arranging the demister place is provided with water leg, collects water and turns back in the recycle slurry liquid pool.
The cross-flow absorption tower comprises in the high speed of the present utility model: column type or disciform recycle slurry liquid pool; The horizontal flue of spray uptake zone; Be arranged on the spray equipment in the spray uptake zone; Oxidation air pipe and side-feeding mixer in the recycle slurry liquid pool.
Cross-flow absorption tower in the above-mentioned high speed, replace countercurrent spray desulfurization in traditional desulfurizing tower with the desulfurization of horizontal flue spray, spray uptake zone and horizontal flue unite two into one, and have cancelled the construction of traditional large desulfurization tower and leading in/out of flue gas, have reduced SR effectively.
Recycle slurry liquid pool of the present utility model be arranged in horizontal flue below, join together with horizontal flue, and greatly reduced floor space.
The utility model has overcome problems such as conventional wet absorption tower floor space is big, volume is big, resistance is big, reduces investment cost and operating cost simultaneously.
Four, description of drawings
Fig. 1 is an at a high speed interior cross-flow absorption tower elevation, and Fig. 2 is an at a high speed interior cross-flow absorption tower vertical view, and wherein: 1 is the recycle slurry liquid pool; 2 is gas approach; 3 is horizontal flue; 4 is spray equipment; 5 is exhanst gas outlet; 6 is agitator.
Five, the specific embodiment
Provide a preferred forms of the present utility model below in conjunction with accompanying drawing 1.
Flue gas enters the absorption tower from horizontal flue import 2, loop slurry is delivered to the spray equipment 4 that is arranged in the horizontal flue 3 by circulating pump from recycle slurry liquid pool 1, the flue gas that horizontal flow is crossed contacts with the loop slurry cross-flow that sprays up and down in horizontal flue 3, finish sweetening process, flue gas is discharged from exhanst gas outlet 5, and the slurries after the desulfurization turn back to recycle slurry liquid pool 1.Agitating device 6 and oxidation unit are installed in the recycle slurry liquid pool 1, prevent the precipitation of slurries and the effective generation that guarantees the desulfurated plaster slurries, the liquid-solid bulk concentration of recycle slurry liquid pool 1 entoplasm reaches 15% when above, discharges processing.
Claims (2)
1. cross-flow absorption tower in the high speed, comprise recycle slurry liquid pool, horizontal flue, spray equipment, it is characterized in that, this absorption tower is a T type structure, the bottom is column type or disciform recycle slurry liquid pool, top is the horizontal flue of spray uptake zone, and spray is furnished with two-layer or three layers of spray equipment in the uptake zone, and spray equipment connects the recycle slurry liquid pool by slush pump and pipeline.
2. cross-flow absorption tower in the high speed according to claim 1 is characterized in that, is furnished with oxidation air pipe and agitating device in the circulation stock tank.
