Description
Technical field
The utility model relates to a kind of garbage combustion device, is the flue gas washing tower that the high-temperature flue gas after the waste incineration is carried out cooling, purifying specifically.
Background technology
At present, in the garbage disposal industry, a large amount of house refuses and part industrial refuse all need to be transported to the garbage reclamation station and reclaim, and finally carry out burning disposal by incinerator.Owing to after rubbish burns in incinerator, can produce a large amount of high-temperature flue gas, and containing a large amount of harmful substance particles in this high-temperature flue gas, directly this high-temperature flue gas being discharged in the atmosphere and can causing severe contamination to environment.Therefore, all need to arrange deduster at the smoke outlet of incinerator, deduster can with a large amount of harmful substance particle removals in the high-temperature flue gas, can reduce the pollution to environment like this.Also have the part garbage combustion device also to increase the flue gas washing tower behind deduster, the flue gas washing tower is to come high-temperature flue gas is carried out cooling, purifying by the principle of spray and heat exchange, thereby further reduces the gas pollution on the environment of discharging.
Traditional flue gas washing tower comprises body, and there is exhanst gas outlet the upper end of body, and there is outlet of sewer the lower end, on the sidewall of body bottom gas approach is arranged; Body interior has heat transfer zone and spray district from bottom to top successively between gas approach and exhanst gas outlet; There is shower the top in spray district, and there is sieve plate the below, and shower stretches out at this external end and is connected with water supply installation.Like this, after entering from the gas approach of flue gas washing tower via the high-temperature gas of deduster dedusting, successively through heat transfer zone heat exchange cooling, spray district washing, purifying, discharged by the exhanst gas outlet of body upper end at last from bottom to top.
Yet, because traditional flue gas washing tower only can carry out one time spray cleaning to flue gas, and the mode of spray cleaning is difficult to the harmful substance particulate in the flue gas is removed, therefore through still also having a small amount of harmful substance microparticle residue in the flue gas after traditional flue gas washing tower washing, can't be up to state standards, directly be drained in the atmosphere or can impact environment.
The utility model content
Problem to be solved in the utility model provides a kind of flue gas washing tower, adopts this flue gas washing tower, can effectively remove the harmful substance particulate in the high-temperature flue gas, and flue gas is fully purified, and it is up to state standards, and can not impact environment.
For addressing the above problem, take following scheme:
Flue gas washing tower of the present utility model comprises body, and it is cylindrical shape.There is exhanst gas outlet the upper end of described body, and there is outlet of sewer the lower end, on the sidewall of body bottom gas approach is arranged.Body interior has heat transfer zone and the first spray district from bottom to top successively between gas approach and exhanst gas outlet.There is the first shower the top in described the first spray district, and there is sieve plate the below, and the first shower stretches out at this external end and is connected with water supply installation.Be characterized between described the first top, spray district and exhanst gas outlet the second spray district being arranged, there is the second shower the top in the second spray district, and there is the bubble-cap support below.Described the second shower stretches out at this external end and is connected with water supply installation.On the described bubble-cap support a plurality of through holes are arranged, the top of through hole all is placed with bubble-cap, and overflow pipe is all arranged around the bubble-cap.
Wherein, described bubble-cap comprises inner core and outer cover, described inner core lower ending opening and being fixed on the through hole of bubble-cap support, and the upper end perforate of inner core and be fixed together by screw and nut and outer cover, the external diameter of inner core is less than the internal diameter of outer cover.Opening is arranged at the bottom of described outer cover sidewall, and the height of this opening is not more than the height of overflow pipe, and the height of overflow pipe is not more than the height of inner core.
The further improvement of the utility model scheme is that the below of described heat transfer zone has sieve plate, gathers and be stacked with some Pall rings in the top of sieve plate.Pall ring can increase heat exchange area, so that the flue-gas temperature after the heat transfer zone heat exchange reduces greatly.
In the such scheme, spraying the spray liquid that uses in the district in described the first spray district and second is the flue gases such as concave convex rod lime absorption spray liquid.This spray liquid can adsorb a large amount of solid particles, further reduces the solia particle in the flue gas.
Take such scheme, have the following advantages:
Because flue gas washing tower of the present utility model is to have increased by the second spray district on the basis of existing flue gas washing tower, and adopt bubble-cap that flue gas is carried out washing, purifying in the second spray district, in this process, flue gas can contact fully with spray liquid, so that the washing, purifying effect is fully complete, therefore the particulate that contains hazardous substance hardly in the flue gas through second spray district's washing, purifying is drained into it in atmosphere and can impact environment.
