Abstract

The invention relates to semi-dry desulfurization equipment, which belongs to the technical field of desulfurization equipment, and comprises a desulfurization tank, a smoke inlet pipe communicated with the bottom end of the desulfurization tank, and a scaling removal mechanism, a smoke exhaust pipe, a transmission screw rod and a circular pipeline; a smoke filtering mechanism is arranged at the upper section in the desulfurization tank, and a plurality of atomization spray guns communicated with the interior of the circular pipeline are arranged on the circular pipeline; the scaling removingmechanism comprises a rotating assembly and two mounting sleeves, each mounting sleeve is provided with two scaling scraping and collecting assemblies, and the two ends of the transmission lead screware provided with two sections of external threads with opposite spiral directions correspondingly. According to the invention, scaling on the side wall of the desulfurization tank can be removed andcollected through the scaling removal mechanism, a transmission lead screw enables a mounting plate and an extension plate to generate rotational flow in the rotating process to prolong the residencetime of flue gas in the desulfurization tank, and the desulfurization effect on the flue gas is improved; in addition, the plurality of filter screens can further filter the exhausted flue gas.

Description

technical field [0001] The invention relates to the technical field of desulfurization equipment, in particular to a semi-dry desulfurization equipment. Background technique [0002] The circulating fluidized bed flue gas desulfurization technology is through the continuous circulation of the desulfurizer in the reactor and the full mixing and contact with the SO2, HF and other gases in the flue gas and chemical reaction, which greatly improves the utilization efficiency of the desulfurizer. With the continuous advancement of technology and the accumulation of experience, the desulfurization efficiency of this method is close to that of the wet method. [0003] The circulating fluidized bed dry flue gas desulfurization device disclosed by the invention with the cited application number of CN200610118960.3 is characterized in that it is composed of a cylinder body, a rotating stirring device, a desulfurizing agent inlet, a fluidized air inlet, a water inlet and a screening ai...
