Abstract

The invention discloses a synergistic device for semi-dry desulfurization and an implementation method thereof. The synergistic device comprises a desulfurization synergist and a desulfurization additive, wherein the desulfurization synergist, air and the desulfurization additive are mixed and ground into a desulfurization mixture, and the mixture is conveyed to a feeding-end flue for sufficient mixing and reacting with sulfur-containing flue gas, CaO and circulating desulfurization ash; and then atomized water is sprayed into a desulfurization tower, and desulfurized flue gas fully reacts with the mixture at the inlet of a chimney. A desulfurization device is composed of an electric dust remover, a pellet main exhaust fan, a flue, a CaO spiral feeder, the desulfurization tower, a bag-typedust remover, a desulfurization fan, the chimney and an efficient desulfurization device, wherein the electric dust remover is connected with the pellet main exhaust fan, the pellet main exhaust fanis connected with the lower end of the desulfurization tower through the flue, the CaO spiral feeder is connected with the desulfurization tower, the upper portion of the desulfurization tower is connected with the bag-type dust remover, the bag-type dust collector is connected with the desulfurization fan, an air outlet flue of the desulfurization fan is divided into two parts, one part is connected with the chimney, the other part is connected with an inlet of the desulfurization tower, and the efficient desulfurization device is connected to the flue.

Description

technical field [0001] The invention relates to the technical field of chemical industry and environmental protection technology, in particular to a semi-dry desulfurization efficiency increasing device and a realization method thereof. Background technique [0002] my country SO 2 The pollution is already very serious, and the SO emitted into the atmosphere every year 2 More than 20 million tons, ranking first in the world. by SO 2 The acid rain pollution hazard area caused by discharge accounts for 30% of the country's land area, which has seriously restricted the sustainable development of my country's economy and society. 2 Pollution control efforts are very urgent. The current flue gas desulfurization technologies mainly include three types: wet method, dry method and semi-dry method. Among them, wet desulfurization has been gradually replaced by semi-dry desulfurization and dry desulfurization due to the problems of white smoke, corrosion and wastewater discharge....
