Waste gas spraying desulfurization tower

The invention discloses a waste gas spraying desulfurization tower, and belongs to the technical field of desulfurization towers. A waste gas spraying desulfurizing tower comprises a tower body and a gas supply pipe, the gas supply pipe provides waste gas for the middle section of the tower body, a shell is installed at the bottom end of the tower body in a penetrating mode, lime water is contained in the shell, and a spraying assembly is installed between the shell and the tower body. A dispersing component is arranged on the inner side of the tower body and between the outlet of the spraying component and the outlet of the gas supply pipe; and the dispersing component is used for dispersing and converging the waste gas and the lime water. Through optimization of the dispersion assembly, during desulfurization reaction, waste gas entering the tower body moves upwards to impact on the bottom surface of the partition plate and is quickly dispersed to the periphery, lime water sprayed downwards can stay and be
