Abstract

The invention belongs to the technical field of environment-friendly construction and in particular relates to a factory flue gas desulfurization and denitrification device for the environment-friendly construction. Aiming at the problems that the design structure is simple, the denitrification efficiency is low and the desulfurization efficiency is low, the invention provides the following scheme: the factory flue gas desulfurization and denitrification device comprises a denitrification chamber, wherein a gas inlet is formed in the middle position of a bottom outer wall of the denitrification chamber; the top of a peripheral inner wall of the gas inlet is connected with a second filtering screen plate through a fastening bolt; the bottoms of inner walls at four sides of the denitrification chamber are connected with a transition pipe through fastening bolts; ammonia gas spraying nozzles, which are distributed at an equal distance, are connected with the outer wall at one side, far away from the denitrification chamber, of the transition pipe through fastening bolts. According to the factory flue gas desulfurization and denitrification device for the environment-friendly construction, the contact efficiency between ammonia gas and flue gas is improved, a catalyst is sufficiently utilized and the denitrification efficiency is improved; the ammonia gas which does not react completely is effectively filtered and subsequent equipment is prevented from being damaged by the ammonia gas; a condition that the deposition concentration of Ca(OH)2 slurry is not uniform is effectivelyavoided; sufficient mixing and contact of ammonia gas and the flue gas is ensured and the desulfurization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection construction, in particular to a plant flue gas desulfurization and denitrification device for environmental protection construction. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry where nitrogen oxides and sulfur oxides are generated. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Ambient air purification benefits a lot.
