Dry-process flue gas desulfurizing method using combined gas jet

Abstract

The invention discloses a drying smoke desulfurizing method by using combined smoke jet. The character is that it adds a smoke jet nozzle above the water nozzle and desulfurizing agent muzzle. It realizes the fully combination of gas, solid and liquid in the desulfurizing reaction tower, increases the desulfurizing efficiency.

Description

technical field [0001] The invention relates to a dry flue gas desulfurization method using a combined flue gas jet, which belongs to the technical field of flue gas desulfurization, and particularly relates to a dry desulfurization system and process in flue gas discharged from various combustion equipment. Background technique [0002] The control of sulfur dioxide gas pollution has always been the focus of environmental protection in most countries in the world, and the pollutants produced by it are the largest source of pollution that has caused damage to the ecological environment in my country. At present, it has become the top priority of air pollution control in my country. [0003] At present, the treatment of sulfur dioxide generally adopts the wet lime-gypsum method (W-FGD) in foreign countries. Although the above-mentioned method has a good removal effect, it has huge investment, large water consumption, large floor area, complex system, There are a series of pro...
