Abstract

The invention relates to the technical field of flue gas desulfurization equipment. The invention further discloses flue gas desulfurization equipment based on the circulating semi-dry method. The equipment comprises a digestion box, single-shaft stirring blades and a mixing atomization pipe, a heat exchange mechanism is arranged above an inner cavity of the digestion box, one end of the heat exchange mechanism communicates with the water inlet end of the mixing atomization pipe, the heat exchange mechanism is a middle section, communicating with a water outlet of a water pump, of the mixing atomization pipe, and the bottom surface of the heat exchange mechanism makes contact with a desulfurizing agent in the digestion box. The heat exchange mechanism is arranged at the upper part betweenthe two single-shaft stirring blades of the digestion box; the heat exchange mechanism is communicated with the mixed atomizing pipe; water flowing through the heat exchange mechanism absorbs heat inthe digestion box and brings the heat to the mixed atomization pipe; by means of the arrangement, heat generated in the equipment can enter a flue gas reactor through a desulfurizing agent outlet in time, so that the evaporation effect on the residual water amount in the flue gas desulfurization reaction process is improved, and energy is reasonably utilized.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization equipment, in particular to a flue gas desulfurization equipment based on a circular semi-dry method. Background technique [0002] At present, there are about forty kinds of flue gas desulfurization technologies for coal-fired industrial boilers, of which more than a dozen are relatively stable in operation, and their desulfurization efficiency can reach the national allowable standard, including direct injection of lime / limestone in the furnace and fluidized bed limestone dry method Flue gas desulfurization, calcium-alkali method, amine-alkali method, sodium-alkali method and magnesium-alkali method and other wet flue gas desulfurization. [0003] The cycle semi-dry method uses the reaction to proceed in the three phases of gas, solid and liquid, and uses the sensible heat of the flue gas to evaporate the moisture in the absorption liquid, so that the final product is dry powder...
