The associated electrical signals for the soot gas flow for flowing through the shell are fed back to the microprocessor (2) by signal feedback device (3)；
When the soot gas flow that electric signal feedback flows through the shell increases, the microprocessor (2) is accordingly controlled
Increase the voltage of the purification device (1)；
When the soot gas flow that electric signal feedback flows through the shell reduces, the microprocessor (2) is accordingly controlled
Reduce the voltage of the purification device (1).
