Pneumatic flow dividing, spraying and desulfurizing equipment

Abstract

The invention discloses pneumatic flow dividing, spraying and desulfurizing equipment. The pneumatic flow dividing, spraying and desulfurizing equipment comprises a gas inlet chamber, a tower body and a gas discharging opening, wherein three layers of spraying devices and a dehydrating and demisting device are arranged in the tower body; a pneumatic flow dividing device is arranged between an outlet of the gas inlet chamber and a first-layer spraying device, and consists of a central column and a plurality of isosceles trapezoid-shaped metal sheets, one ends of the metal sheets are welded to the central column through connecting pieces, the other ends of the metal sheets are fixed on the inner wall of the tower body through the connecting pieces, included angles between the metal sheets and the horizontal direction are between 22 DEG and 30 DEG, and the circumference consisting of the whole metal sheets has a ventilation rate of about 40%, so that the rotary ascending velocity of flue gas flow is increased, kinetic energy of the flue gas flow is increased, ascending flue gas flow can hold absorption liquid sprayed down from the upper side, and the strong mass transfer time between a gas phase and a liquid phase is extended, thus SO2 and dust particles in flue gas can be well reacted and adsorbed, and the high desulfurizing and dust removing efficiency is realized; meanwhile, according to the pneumatic flow dividing, spraying and desulfurizing equipment disclosed by the invention, an absorption liquid circulating system has the advantages of low energy consumption and low operation cost.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to a pneumatic split flow spray desulfurization equipment for industrial tail gas desulfurization. Background technique [0002] Desulfurization equipment is a kind of purification equipment that discharges dust, waste gas and other harmful substances in the field of industrial production. At present, the wet flue gas desulfurization purification equipment generally consists of a tower body and one to three layers of spraying devices and demisting devices in the tower body. The tower body is a whole body from bottom to top. After the flue gas enters the tower body, it quickly reaches the top of the tower. The contact time between the flue gas and the spray water is very short, so the desulfurization and dust removal effect is not ideal, especially for high concentration and large flue gas volume. The exhaust gas control effect is even less ideal. Contents o...

The tower body is a whole body from bottom to top. After the flue gas enters the tower body, it quickly reaches the top of the tower. The contact time between the flue gas and the spray water is very short, so the desulfurization and dust removal effect is not ideal, especially for high concentration and large flue gas volume. The effect of exhaust gas treatment is even less ideal
