Background

The flue gas desulfurization and denitration technology is a boiler flue gas purification technology applied to the chemical industry of generating multi-nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. The application of this technology is of considerable benefit for ambient air purification. Known flue gas desulfurization and denitration technologies include a PAFP (polyamide-formaldehyde filter), an ACFP (Acrylonitrile-co-fired Filter), a pyrolusite method, an electron beam ammonia method, a pulse corona method, a gypsum wet method, a catalytic oxidation method, a microbial degradation method and the like, most of the flue gas desulfurization and denitration technologies are in research and industrial demonstration stages, but because the flue gas desulfurization and denitration technologies can simultaneously realize desulfurization and denitration in a set of system, particularly along with continuous strictness of NOx control standards, the desulfurization and denitration technologies are increasingly emphasized by various countries. The simultaneous flue gas desulfurization and denitration technology mainly comprises three types, wherein the first type is a combined technology of flue gas desulfurization and flue gas denitration; the second type is that SOX and NOx are removed simultaneously by using an adsorbent; the third type is to modify the existing Flue Gas Desulfurization (FGD) system (such as adding a denitration agent into a desulfurization solution) and add a denitration function.

For example, the chinese patent application No. CN201920034245.4 is a baffle demister for a desulfurization tower, comprising a demister main body assembled by a plurality of baffle modules, where the baffle modules include a plurality of baffles and a connecting piece for connecting each baffle, the connecting piece includes a clamping tube and a plug pin rod, the bottom of the clamping tube is provided with transverse notches at equal intervals matched with the thickness of the baffles, the top and the bottom of each baffle are provided with a plurality of plug pin holes along the length direction, and after the clamping tube is clamped with the baffles at the baffle plug pin holes, the plug pin rod penetrates through the plug pin holes of each baffle in the clamping tube. The utility model discloses a each baffling board and baffling board module are connected to the connecting piece, and joint strength is high, has solved the joint strength that the tradition adopted the viscose connected mode to cause and has hanged down, the unstable problem of high temperature.

Based on the technical scheme, the invention designs the anti-scaling high-efficiency demister for the desulfurizing tower to solve the problems.
