Abstract
The invention relates to a smoke washing device. A washing tower of the smoke washing device comprises a cooling adsorption washing area and an adverse current adsorption washing area. When smoke passes through the cooling adsorption washing area, partial pollutant such as smoke dust in the smoke can be removed, volume flow rate of the smoke is reduced simultaneously, and sectional area of the adverse current adsorption washing area is favorably reduced. In the adverse current adsorption washing area, the smoke dust in the smoke can be absorbed through sufficient contact between the smoke dust and a liquid film, and simultaneously pollutant such as sulfur dioxide can be sufficiently reacted. By means of the smoke washing device, high-efficient smoke dedusting desulfuration is achieved. In addition, washed smoke and heated air are mixed and then discharged out, smoke humidity is reduced, and rime fog at an air outlet of the smoke washing device is avoided. The smoke washing device is small in size, light in weight and applicable to flue gas treatment of a host machine and a boiler of an offshore platform or a traveling ship, and meets miniaturization requirements of on-land fume treatment equipment.
