(EN) A wet FGD: the upper square tower fixed with pure flue gas flue and raw flue gas flue whose widths same as that of the square tower, the flue are respectively shrunk to fit pure flue and raw flue, so eradicate entirely turbulence and bias flow field of flue gas. Flue gas is following then against with spraying slurry so can eradicate the pressure loss, cancel BUF. Oxidation air and predissolved absorption slurry are directly fed into spray zone so cancel Roots blowers. Instantly accomplish desulfurization. Realize running without dirtiness, so need no demister or only a simple metal demister, and the pure flue gas passage needs no corrosion protection, the naked tower is also a bypass flue.
