Experimental Study on Influence of Gas Flow on Trichel Pulse Discharge

[摘要] Negative corona discharge is the basis of electrostatic precipitator(ESP) which has been widely used in various production fields due to its significant advantages. The characteristics of negative corona discharge have an important impact on dust removel efficiency of ESP. In this paper, the influence of airflow on negative corona discharge has been studied experimentally based on needle-net discharge model which is simplified of ESP discharge electrodes. Using statistical method, the influence of airflow on the parameters of Trichel pulse was analyzed. According to the simulation results of the negative ion desity distribution in the discharge zone by COMSOL software, the reasonable explanation for the experimental results is given.
