A removal device for dry multi-pollutant integrated removal

Abstract

The invention discloses a removal device for the integrated removal of multi-pollutants in a dry process. An inlet flue (2) and an outlet flue (7) are respectively arranged on both sides of the removal device. The inlet flue (2) and the outlet flue (7) A removal reactor is arranged between the outlet flue (7), and at least three flow plates are arranged in the removal reactor, and carbon-based materials for removing pollutants in the flue gas are filled between adjacent flow plates Particles, the flue gas passes through the flow plate from the inlet flue (2) and uses the carbon-based material particles to remove pollutants in the flue gas and is discharged from the outlet flue (7). A removal device for the integrated removal of dry multi-pollutants of the present invention can remove pollutants such as SO2, NOx, etc., improves the removal efficiency of the removal device, and reduces the pressure drop of the device and material wear; It can make the flue gas enter the removal device evenly, improve the reaction speed between the flue gas and the carbon-based material particles, and realize the rapid removal of pollutants; improve the fluidity of the carbon-based material particles.

Description

technical field [0001] The invention relates to a reactor for removing pollutants, in particular to a removal device for integrated removal of multiple pollutants in a dry process. Background technique [0002] SO emitted during coal combustion 2 , NOx and other pollutants have become the main source of air pollution. According to statistics, SO 2 Approx. SO 2 More than 85% of the total emissions, and more than 67% of the total NOx emissions. At present, for the control of various pollutants in the flue gas, separate removal technologies are mostly used at home and abroad. With the continuous increase of the types of pollutants controlled, the continuous expansion of pollutant purification equipment, regardless of the investment and operation costs or the complexity of the purification system All face great difficulties. Therefore, it has become a research hotspot at home and abroad to develop efficient and low-energy-consumption combined removal technologies for multipl...
