Abstract

The present invention provides one kind of horizontal inclined rotary fluidized bed desulfurizing reactor. The desulfurizing reactor is one double-layer structure including a truncated cone inner barrel with grid plate structure in the side wall, closed small caliber end and great caliber end as the gas outlet; and an outer barrel. There is a ring inlet channel formed between the small caliber end of the inner barrel and the outer barrel, the outer wall of great caliber end of the inner barrel is connected to the outer barrel, and the inclined reactor has outlet end higher than the inlet end. The present invention combines the fluidizing pneumatic force and the rotary centrifugal force well to realize the full reaction between SO2 and the desulfurizing agent grains, and has long reaction gas remaining period, high utilization rate one desulfurizing agent, and high desulfurizing efficiency up to 90-97 %.

Description

technical field [0001] The invention relates to the field of environmental protection for treating gas pollutants in flue gas, in particular to the structural design of a horizontal rotary fluidized bed desulfurization reactor. Background technique [0002] Fluidized beds are widely used in the fields of energy, environmental protection and chemical industry. The desulfurization reactor is the core device of the desulfurization process. Its technology and desulfurization index will restrict and determine the efficiency of the desulfurization process. The reactor is filled with a certain amount of desulfurization agent materials (such as limestone, desulfurization agent and other particles), and the gas from the intake air The gas is fed into the inlet, and the gas drives the material to move and fluidize in the reactor, and a neutralization reaction occurs to achieve the purpose of desulfurization. The inner cylinder of the existing horizontal fluidized bed desulfurization ...
