ELECTRIC PRECIPITATION METHOD AND ELECTRIC PRECIPITATOR

摘要

PROBLEM TO BE SOLVED: To suppress the lowering of dust collection efficiency by preventing the lowering of charge voltage even if spark discharge occurs frequently. SOLUTION: Charging is interrupted for a predetermined period in the same way as a conventional method only when spark discharge having possibility transferring to arc discharge is generated but continued as it is when spark discharge having no possibility transferring to arc discharge is generated.
