Boiler flue gas desulfurization and denitrification device

Abstract

The invention discloses a boiler flue gas desulfurization and denitrification device, which belongs to the technical field of flue gas desulfurization and denitrification equipment, and comprises a cylinder body, a top cover, a gas inlet pipe, a gas outlet pipe, a gas inlet pipe and a gas outlet pipe, the filtering mechanism is mounted in the top cover, and the lower end of the filtering mechanism extends into the barrel; the spraying mechanism is used for spraying gas in the cylinder body; the spraying uniformity can be effectively improved through the spraying mechanism, so that the actual using effect and the using quality can be guaranteed; the filtering mechanism is arranged to purify and filter the sprayed gas, the aperture of the second filter screen is larger than that of the first filter screen, and the first filter screen and the second filter screen are arranged to achieve the purpose of twice purification and filtration, so that the cleanliness of the sprayed gas during output can be ensured; and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization and denitration equipment, in particular to a boiler flue gas desulfurization and denitration device. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in the chemical industry where polynitrogen oxides and sulfur oxides are generated. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Therefore, the application of this technology has many benefits for ambient air purification. Known flue gas desulfurization and denitrification technologies include PAFP, ACFP, pyrolusite method, electron beam ammonia method, pulsed corona method, gypsum wet method, catalytic oxidation method, and microbial degradation method. [0003] However, the desulfurization and denitrification devices on the market still have various problems. For example, the desulfurization and denitrificati...

Problems solved by technology

[0003] However, the desulfurization and denitrification devices on the market still have various problems. For example, the desulfurization and denitrification devices in the prior art cannot spray the washing liquid on a large area during the actual work process, so that the flue gas desulfurization and denitrification cannot be achieved ideally. The washing effect has certain limitations, so we propose a boiler flue gas desulfurization and denitrification device
