A smoke channel is arranged between the precooler and the sulfur dioxide absorber, the precooler has a discharging channel for discharging coolant and the absorber has a discharging channel for discharging water. The utility model has the advantages of high absorption efficiency of sulfur dioxide and low cost of production and operation.
Description
The utility model relates to apparatus for absorbing SO 2 from fume by seawater method, belongs to environmental protection technical field, is applicable to the occasion of the acid pollution materials such as sulfur dioxide in the facility institute discharged flue gas such as eliminating coastal industry device such as thermal power plant coal-burning boiler.
Because the needs of environmental protection control acid rain must remove sulfur in smoke that industrial equipment discharges such as fire coal.Prior art is to install flue gas desulfurization equipment additional on above-mentioned industrial plants, and these flue gas desulfur devices all must use certain sulfur dioxide absorbent, with the absorbing and removing sulfur in smoke.Natural sea-water is because natural alkalinity that it had makes it become cheap and good sulfur dioxide absorbent, thus make coastal industrial plants use cheap and efficiently desulfuration of flue gas by sea water technology had advantageous supremacy clause.The desulfuration of flue gas by sea water device, with the natural sea-water flue gas that spray washing flows through in absorber that extracts, the clean flue gas that has been washed sulfur dioxide can directly enter atmosphere by chimney; Washed the draining behind the sulfur dioxide,, therefore its quality recovery can have been entered the nature marine site after satisfying environmental requirement because wherein the minute quantity sulfate that increases is safe and harmless for marine environment.Because the flue gas that is washed is to come from commercial plant such as coal-burning boiler, the cigarette temperature often surpasses 130 ℃ Celsius, can not directly absorb the operation of sulfur dioxide to it, so must carry out pre-cooled to flue gas.Existing seawater method apparatus for absorbing SO 2 (Fig. 6), because its precooler is positioned at below, absorber inside, because of having absorbed the pre-cooled water that flue gas heat has higher water temperature, converge at absorber bottom and the acid seawater that has absorbed sulfur dioxide, thereby offseted pre-cooled effect, the sulfur dioxide that causes dissolving in liquid phase is overflowed again, thereby causes system's desulfuration efficiency to descend.Simultaneously, because the spray facility of absorber is located at precooler top, thereby must corresponding lifting as the lift of the seawater of absorbent, the rising significantly that this has just caused systematic running cost to use.Because desulfuration efficiency is low and the high critical defect of operating cost, the use of said apparatus is subjected to strict restriction.
The purpose of this utility model is, overcomes the deficiencies in the prior art, improves the process structure of desulfuration of flue gas by sea water device, make its can be more efficiently, build at low cost and move.
The technical scheme of apparatus for absorbing SO 2 from fume by seawater method of the present utility model is: it comprises precooler and absorber, and precooler discharge cooling medium and absorber draining have passing away separately.It is achieved in that precooler and absorber constitute (Fig. 2) by two cavitys respectively, between two cavitys exhaust gases passes is arranged, and precooler discharge cooling medium and absorber draining are provided with passing away separately.Precooler and absorber also can be two independent tower bodies (Fig. 3), have exhaust gases passes to connect between two tower bodies, and precooler discharge cooling medium and absorber draining are provided with passing away separately.The cooling medium that precooler uses can be that water for industrial use, seawater, air or other are suitable for use as the liquid or the gas of cooling medium.The heat absorption mode of precooler can be cooling medium directly spray (Fig. 2, Fig. 3) or with cooling medium by heat exchange element absorb heat (Fig. 4, Fig. 5).Precooler can be that flue gas enters pipe self formation.When the heat absorption mode of precooler was the structure of absorbing heat by heat exchange element with cooling medium, precooler can be located at the absorber below and be arranged at same tower body (Fig. 5) with absorber, and cooling medium also can have independent passing away.
