Low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification

Abstract

The invention relates to the technical field of flue gas purification, and discloses a low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification. Thedevice comprises a machine body, and further comprises a water vapor generator, a carbon-based purification mechanism and a secondary filtering mechanism, a desulfurization and denitrification chamberis arranged in the machine body, a carbon-based catalyst is arranged in the desulfurization and denitrification chamber, and the inner wall of the desulfurization and denitrification chamber is fixedly connected with a machine box. Flue gas is subjected to a desulfurization reaction with water and oxygen under the action of the carbon-based catalyst, then the flue gas is subjected to a denitration reaction, an ammonia gas bottle conveys ammonia gas to an ammonia gas main pipe, the ammonia gas enters the desulfurization and denitration chamber through an ammonia gas branch pipe and an ammoniagas channel and an ammonia spraying opening which are arranged in a rotating shaft, and flue gas turbulence is improved under the stirring action of the rotation of fan blades, so that the flue gas and the ammonia gas are fully mixed to generate denitration reaction. The desulfurization and the denitration are carried out in the same desulfurization and denitration chamber, and the purposes of synchronous desulfurization and denitration, uniform mixing of ammonia and flue gas and improvement of flow field uniformity are achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a low-consumption carbon-based catalytic desulfurization and denitrification device for flue gas purification. Background technique [0002] The flue gas combined desulfurization and flue gas pollutant control technology using carbon-based catalysts as adsorbents and catalysts can realize the integration of desulfurization, denitrification, mercury removal, heavy metal removal, and dust removal, and eliminate white smoke.
