Abstract
The invention discloses a micro-vortex rotary demisting apparatus for ammonia-based desulphurization. The apparatus comprises a cylinder, a central column, and vortex boards. The cylinder is internally equipped with a coaxial central column provided with a plurality of vortex boards. The bottom edges of the vortex boards come into contact with the bottom edge of the cylinder, and the central column is in fixed connection to the inner wall of the cylinder through a supporting rod. Through the vortex boards, standing vortexes are generated in flue gas and flue gas is forced to rotate at a high speed in the apparatus. In the combined action of turbulent flow, centrifugal force, spouting and gravity, liquid drops and dust with different particle size distribution in the flue gas collide to each other and form large liquid drops. The large liquid drops are captured and removed. The purified flue gas meets the need of efficient capture of fine dust of flue gas arranged at an outlet of a desulfurizing tower. The apparatus is high in demisting efficiency, compact in structure, high in operation reliability, and low in investment and operation energy consumption.
