Abstract

The present invention features that line as desulfurizer material is made to pass through one clean wet fume slaking equipment to form slaked lime desulfurizer with high surface activity. In the system, there are three kinds of circulation modes, including inner circulation of desulfurizer grains; outer circulation and circulation of clean wet fume. The present invention is superior to available technology in that desulfurizing efficiency up to 90-92 % may be reached at relatively low Ca / S ratio, 1.1-1.3; that wide regulation ratio characteristic can meet the high efficiency desulfurizing requirement in load of the combustion equipment from 20% to 110%, and that the present invention has low water consumption and low cost.

Description

Technical field

[0001] The invention relates to a composite circulating fluidized dry flue gas desulfurization process and a desulfurization reaction tower, belonging 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 causes damage to the ecological environment in our country. It has become a top priority for air pollution control in my country.

[0003] At present, for the treatment of sulfur dioxide, the wet lime gypsum method (W-FGD) is generally adopted in foreign countries. Although the above method is adopted, although the removal effect is better, it has huge investment, large water consumption, large area, complex s...
