[0002] Flue gas and other polluted gases must be desulfurized and dust-removed before they can be discharged into the atmosphere. Existing desulfurization and dust removal towers usually use reaction solvents for desulfurization, but there are a large number of carbon-containing particles in the flue gas, which causes the flue gas to turn gray and black. It is necessary to add an activated carbon adsorption filter layer to de-whiten the flue gas, and the filter layer is mostly fixed and difficult to replace.

Through the bending design of the flue pipe, in conjunction with the first air guide folding plate and the second air guide folding plate provided in the spray tower body, the flow rate of the gas can be slowed down to a great extent, thereby increasing the residence time of the gas in the upper part of the spray tower body, and the inclined surface setting on the first air guide folding plate and the second air guide folding plate, in conjunction with the setting of multiple through holes, while ensuring the normal flow of desulfurization slurry droplets, it also increases the residence time of the desulfurization slurry droplets in the upper part of the spray tower body, thereby greatly improving the efficiency of the preliminary mixed desulfurization; however, the above-mentioned spray tower cannot solve the problem of inadequate flue gas desulfurization, and it is difficult to meet the emission standards.
