摘要
Equipment and a method for circulating fluidized bed semidry simultaneous desulfurization and denitration of a sintering flue gas, comprising an ozone generator (2), a diluting blower (1), a mixing buffer tank (3), an ozone distributor (4), and a circulating fluidized bed (CFB) reactor tower (9). When evenly mixed by the mixing buffer tank (3), ozone is injected into a flue (4′) via the ozone distributor (4); and, an oxidized flue gas is introduced into the CFB reactor tower (9), where NOx, SO2, and SO3 in the flue gas are reacted with a Ca-based absorbent under the action of atomized water in the reactor tower, thus implementing simultaneous removal of SOx and NOx. This provides the characteristics of a simple system, great performance, small footprint, and inexpensive investments.
