Abstract

The invention discloses a dust-gas mixing device for semi-dry desulphurization reactors, which comprises a dust-gas mixing section, wherein the lower port of the dust-gas mixing section is a flue gas inlet, the upper port of the dust-gas mixing section is a flue gas outlet, and the cross-sectional area of the flue gas outlet is greater than that of the flue gas inlet; the right side face of the dust-gas mixing section is provided with a mixed dust inlet; and the inside of the dust-gas mixing section below the mixed dust inlet is provided with a declivitous distributing plate. The dust-gas mixing device disclosed by the invention has the advantages that flue gas is fed into the dust-gas mixing device from the flue gas inlet at the lower part of the dust-gas mixing section, and mixed dust is fed into the dust-gas mixing device from the mixed dust inlet; and under the action of the distributing plate, the mixed dust and the flue gas are excited and mixed and uniformly distributed in the whole cross section of the dust-gas mixing device, so that a flue gas purifying device keeps efficient operation.

Description

technical field [0001] The invention relates to an ash gas mixing device for a semi-dry desulfurization reactor. Background technique [0002] Semi-dry flue gas desulfurization technology often adopts desulfurization ash circulation humidification technology to improve the utilization rate of desulfurization agent and desulfurization efficiency. It enters the reactor in the form of flow, and reacts with the hot flue gas from the boiler to remove sulfur dioxide and other substances in the flue gas. Through the circulation of desulfurization ash, the effective desulfurization agent content in the reactor is greatly increased, and the desulfurization efficiency is improved. The ash in the reactor The load is also greatly increased. Whether the mixed ash is evenly distributed on the cross-section after entering the reactor has a great relationship with the flue gas desulfurization effect, and also has a certain influence on the stable operation of the reactor. [0003] When th...
