Evaluation analysis and development overview of electrostatic precipitator

The domestic standards for electrostatic precipitator about pressure drop and leakage rate were analyzed. The electrostatic precipitator was evaluated from three aspects,including environment protection,performance and management. In order to effectively control the dust emission,the outlet dust concentration should be reduced below the standard emission limit. The on-line monitoring system was established,body pressure drop and leakage rate was degraded,and the removal efficiency and system operation rate and the product components standardized coefficient was enhanced. The new electrostatic precipitator technologies,including wet electrostatic precipitator and electrical bags composite,were demonstrated. The future research direction for electrostatic precipitator was discussed,including adjustment of dust specific electric resistance by means of adjusting the temperature and humidity of flue gas,adding other chemical substances,selecting appropriate form of electrode and wide spacing,setting reasonable flow guide device,and checking regularly the operating equipment in order to solve the problem of air leakage. According to the practical operation,suitable power supply system and dedusting system will be adopting.
