Background
A large amount of sulfur dioxide discharged from industrial flue gas needs to be treated, and common desulfurization processes comprise wet methods, dry methods and other technologies. The wet desulphurization process has the main advantages of over 99 percent of desulphurization efficiency, simple operation and maintenance and high one-time investment, large occupied area and large water consumption. The key device of the wet desulphurization process is a desulphurization tower, and the traditional desulphurization tower generally adopts a vertical round steel internal anti-corrosion hollow towerSpraying, wherein the flue gas rising from the bottom and the desulfurized slurry sprayed from the top carry out desulfurization reaction in a countercurrent manner, the liquid-gas ratio is high, the water consumption is high, the flow rate is low, the diameter of the desulfurizing tower is large, the residence time is long, the height of the desulfurizing tower is high, and the investment and energy consumption are high. In order to improve the desulfurization efficiency and save investment and energy consumption, a tray technology and a rotational flow technology are developed on the basis of an empty tower, and the tray technology and the rotational flow technology have advantages and disadvantages in application. Wherein the tray technique is similar to chemical plate tower structure, sprays the tray that the layer set up a circular equipartition trompil promptly at the desulfurizing tower, and the primary function makes the flue gas flow equalize and slurry mixing reaction, improves desulfurization efficiency, establishes double-deck tray for improving desulfurization efficiency sometimes, but the resistance increase. The disadvantage of tray technology is that, although it is more efficient than the empty column desulfurization, it is more efficient for SO2The flue gas with higher original concentration can not realize ultralow emission desulfurization, and simultaneously slurry is accumulated on a tray to often cause deposition and scaling and even block open pores. The cyclone technology is formed by uniformly distributing N cyclones similar to an exhaust fan structure under a spray layer of the desulfurization tower, the gas-liquid-solid three-phase full contact is realized by utilizing the gas dynamics forced turbulent flow mass transfer principle, the mass transfer rate is improved, the aim of improving the desulfurization efficiency is achieved, the cyclone technology has the advantage of higher desulfurization efficiency, the resistance is higher, more than 500 plus 1000Pa is generally increased compared with a tray, the energy consumption of a follow-up fan motor is increased, in addition, the fixed cyclones strongly scour glass scale anti-corrosion layers of an upper spray layer, a supporting beam and a desulfurization tower wall plate in the flue gas cyclone application, and the anti-corrosion layers are easily abraded, shed and corroded. The above disadvantages limit the popularization and application of the empty tower, tray and rotational flow technology.
