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.

Description

technical field [0001] The invention relates to a flue gas desulfurization and dust removal technology, in particular to a flue gas washing device. Background technique [0002] At present, the flue gas generated by domestic and foreign offshore platform facilities (such as main engines and boilers) is basically discharged directly into the atmosphere, and the problem of flue gas pollution has not been effectively resolved. Due to the limitations of space and environment of offshore platforms and ships, such as floor area, load-bearing capacity, safety, equipment height restrictions, and climate factors such as typhoons and waves, offshore platforms and ships have high requirements for flue gas scrubbers. requirements. Therefore, there is a need for a device that can efficiently process flue gas that can meet the requirements of offshore platforms and sailing ships. Contents of the invention [0003] Aiming at the above technical problems, the present invention designs a...
