Following the trend of eco-conscious, more people pay attention to environmental issues in recent years, the environmental pollution led government to increase restrain on emission standard of industrial air pollution. For enterprises, they must comply with regulation requirements. In addition, how to reduce exhaust emissions with limited resources and improve the performance of control equipments is an important task of the industry. The purpose of this study is to enhance the performance of acid exhaust treatment equipments and reduce their operating costs by performing five research tasks. This study utilizes the concept of pre-washing in order to enhance the treatment efficiency. By setting sprinklers in the pipe, the emission concentrations of F- and Cl- at the stack exit were reduced by about 10 to 30%. By configuring the cycle sprinkler piping on the inside of horizontal scrubber and installed maintenance hole on either sides of the bottom of scrubber, it could reduce the accumulation of sludge sedimentation and still could be maintained when the equipment was continuously in operation. The growth speed of the bacteria on the inside of scrubbers could be weaken by isolating the light transmittance of wet scrubbers, thereby reducing obstructions in the scrubber and extending the periodicity of maintenance. And by setting sprinklers above the windmill impeller in order to improve the crystal adhesion situation, it could help to improve the windmill operating efficiency and reduce its operating cost. And demolition of non-essential parts around wet scrubbers such as check damper could reduce the operating pressure loss and saving operating costs.
