Description

Technical Field

[0001] The utility model relates to the field of desulfurization and denitration tower equipment, in particular to a flue gas desulfurization and denitration tower which is convenient to assemble and disassemble. Background Art

[0002] Flue gas desulfurization and denitrification tower is a boiler flue gas purification technology used in the chemical industry that produces a lot of nitrogen oxides and sulfur oxides. During the use of the flue gas desulfurization and denitrification tower, circulating water is needed to facilitate circulating spraying inside it. The existing flue gas desulfurization and denitrification tower has poor filtering effect of circulating water. When people use the flue gas desulfurization and denitrification tower, they cannot filter the circulating water thoroughly, which easily causes the spraying device to be blocked, affecting its spraying effect, making it inconvenient for people to use, and reducing the practicality of the flue gas desulfurization and denitrification tower;

[0003] Among them, the application number is "CN201921466974.3" and is a flue gas desulfurization and denitrification tower with good circulating water filtration effect. The utility model achieves the advantage of good circulating water filtration effect by arranging a bottom plate, a desulfurization and denitrification tower body, a filtering device, a reflux pipe, a water tank, a spraying device, a grille plate, a guide plate, a fixed block and a spraying pipe. The cooperation of each other solves the problem of poor circulating water filtration effect of the existing flue gas desulfurization and denitrification tower and improves the practicability of the flue gas desulfurization and denitrification tower; however, the filtering device inside the flue gas desulfurization and denitrification tower is installed in the inner cavity. Long-term filtration operation causes the internal filtration impurities to accumulate, thereby affecting the filtration effect. Since it is inconvenient to disassemble and assemble the filtering device, the subsequent maintenance and replacement of the internal filter plate body is more cumbersome. Utility Model Content
