The applied external electric field can improve the recovery efficiency of circulating cooling water

so it is necessary to analyze the transport characteristics and influencing factors of micro-droplets in electrostatic equipments. In this paper

the drag force under the velocity field is solved by using the k-? turbulent model and the momentum equation. The electric field distribution was solved by the current continuity equation and Poisson equation. The transport characteristics and trajectories of the droplets and the distribution of electric potential field and intensity in electrostatic equipment sare studied under electric field with low Reynolds number turbulence. The results show that

micro-droplets with smaller diameter are more likely affected by the turbulent air flow

resulting in a longer slip distance and then the collecting efficiency will be reduced in the electrostatic equipments. With the decrease of airflow velocity

the electric charging and flowing time of the micro-droplets in the equipments increase and the collection efficiency of the micro-droplets in the electrostatic equipments becomes larger. In fact

the inlet electric potential directly affects the saturation charge number of the micro-droplets

especially for the droplets with a smaller diameter

the lower the saturated charge number and the lower the collection efficiency. Therefore

the collection efficiency of the circulating cooling water can be improved by increasing the working voltage and decreasing the distance between the collecting plates and selecting a reasonable airflow velocity.
