Semi-dry method efficient desulfurization system

Abstract

The invention relates to the technical field of desulfurization equipment, and provides a semi-dry method efficient desulfurization system. The system comprises a desulfurization agent preparation system and a desulfurization system body; the desulfurization agent preparation system comprises a quicklime bin, the lower end of the quicklime bin is in penetrating connection with a rotary feeding device, the driving end of the rotary feeding device is connected with a rotating shaft of a first motor, and the other end of the rotary feeding device is in penetrating connection with a digestion tank; the upper end of the digestion tank is in penetrating connection with a first water inlet pipe, the other end of the first water inlet pipe is connected with an external water source, and the side wall of the digestion tank is in penetrating connection with a slurry tank through a first connecting pipe. The defects in the prior art are overcome, the design is reasonable, the structure is compact, and the problems are solved that an existing SDS desulfurization system is poor in desulfurization effect and meanwhile, when an SDA desulfurization system is adopted, sufficient contact between a desulfurization agent solution and sulfur-containing flue gas cannot be ensured. A series of structural combinations are adopted, so that the desulfurization efficiency is improved, and the system hashigh practicability and commercial value.

Description

technical field [0001] The invention relates to the technical field of desulfurization equipment, in particular to a semi-dry high-efficiency desulfurization system. Background technique [0002] With the increasingly serious environmental protection situation, the requirements for the emission indicators of various pollutants are becoming increasingly strict. During the operation of the sintering machine, a large amount of flue gas will be generated. These flue gases contain a large amount of sulfide gas, which seriously pollutes Air, in order to desulfurize the flue gas of the sintering machine to meet or meet lower emission standards, it is usually equipped with a corresponding desulfurization system or device. [0003] The traditional desulfurization device uses NaHCO3 as the desulfurizer, that is, the SDS desulfurization system. NaHCO3 is decomposed at high temperature to produce NaCO3 particles, and NaCO3 reacts with SO2 and SO3 to solve the content of sulfide in the a...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a semi-dry high-efficiency desulfurization system, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and solves the problem of poor desulfurization effect of the existing SDS desulfurization system. The SDA desulfurization system cannot ensure sufficient contact between the desulfurizer solution and the sulfur-containing flue gas. This application adopts a series of structural combinations to improve the desulfurization efficiency and has strong practicality and commercial value.
