Research on grounding electrode atomized corona discharge precipitator
The main problem facing the current atomized corona discharge and dust removal technology is the electrode fatness caused by uneven water distribution on the surface of the discharge electrode,and the discharge performance is thus limited.In order to solve this problem,a grounded-pole atomized corona dis-charge precipitator with threaded uniformly distributed water electrodes is designed,and discharge and dust removal experiments are carried out.The discharge characteristics are analyzed in detail,the effects of positive and negative corona discharge on voltammetric characteristics are studied,and the effects of flow rate and spacing of poles on the corona voltage,voltammetric characteristics,and spark discharge voltage are investigated,and it is determined that the grounded-pole atomized corona discharge dust col-lector has excellent discharge performance and removal performance.Experimental investigation of the control of the two poles spacing of 25 mm flow rate of 10 mL/min negative corona discharge can obtain the best discharge characteristics;at the same time,from the comparison of experiments that the grounding electrode atomized corona discharge dust removal efficiency stability is better than the traditional corona discharge,control flow rate of 10 mL/min to obtain the maximum dust removal efficiency.
