The automatic dosing device of the wet scrubber integrates the PP dosing mixing tank, PH ONLINE DETECTION, electronic control system and liquid level gauge. The automatic dosing equipment realizes the purpose of adding acid at high level or adding alkali at low level according to the pH value interval set by the control system. A certain concentration of chemicals is automatically added to the circulating water tank of the scrubber through a metering pump, and the acid and alkali waste gas is in the packing layer and contacts the sprayed chemicals to achieve the purpose of absorbing and neutralizing the acid and alkali waste gas.
