Description
Technical Field
The utility model relates to a technical field is administered to the flue gas, concretely relates to take absorption tower of porous tray.
Background
Flue gas generated by a coal-fired boiler generally needs denitration, dust removal and desulfurization, and pollutants in the flue gas are removed and then discharged into the atmosphere. The desulfurization generally adopts a limestone-gypsum desulfurization process, a spray empty tower is arranged, and a slurry pool area, a tray area, a spray area and a demisting area are arranged in the tower.
The temperature of the inlet smoke of the wet desulphurization is generally more than 120 ℃, and the smoke temperature is reduced to about 50 ℃ after the smoke is washed by the slurry sprayed by the spraying area and is in a saturated wet smoke state. Because the cooling range is obvious, the moisture that the thick liquid carried evaporates in the flue gas in a large number, in order to maintain the water balance in the absorption tower, need wash through the defroster and carry out a large amount of moisturizing. That is, the majority of the water in the absorber is lost due to evaporation. The moisture carried away by the smoke is discharged through a chimney and condensed into fine liquid drops when exchanging heat with the ambient air to form white smoke plume. On the other hand, in water-deficient areas, the operation cost is high because wet desulphurization requires a large amount of water.
