Abstract

The invention relates to an energy-saving and efficiency-improving device of a wet desulphurization spray tower. The device comprises a coke oven flue; the coke oven flue is communicated with an external induced draft fan; the free end of the coke oven flue is communicated with a first desulfurization tank, and the upper portion of the first desulfurization tank is communicated with a second desulfurization tank; the top end of the second desulfurization tank is communicated with a dust remover connecting pipe; and a desulfurizing agent connecting pipe is arranged on the side wall of the second desulfurization tank in a communicating manner. The structure of an existing wet desulphurization spray tower is improved, and in the using process of the improved wet desulphurization spray tower, the effects of saving energy and reducing consumption can be achieved through timely mixing and contact of flue gas and slurry; and meanwhile, the effect of efficient desulfurization of the flue gas can be achieved through multiple times of desulfurization of the flue gas.

Description

technical field [0001] The invention relates to the technical field of wet desulfurization, in particular to an energy-saving and efficiency-improving device for a spray tower of wet desulfurization. Background technique [0002] At present, my country's petrochemical, pharmaceutical, thermoelectric, steel, metallurgy, cement and other industries mainly use wet flue gas desulfurization technology to remove sulfur dioxide in flue gas. The desulfurization tower is the most critical core equipment in the wet flue gas desulfurization process system. According to different technical characteristics, it can be divided into spray towers, bubbling towers, liquid column towers, etc. The mainstream tower type is usually arranged in the way of countercurrent contact between flue gas and slurry. After the spray layer nozzle close to the tower wall sprays the absorption liquid to the inner wall of the desulfurization spray tower, the absorption liquid will flow down along the tower wall...
