The Control of Constant Current Source in Electrostatic Precipitators Based on Microcontroller

Abstract:

In order to improve the efficiency of electrostatic precipitators, a control system of constant current source based on Single Chip Microcomputer (SCM) is designed. In the control process, we use the pulse signal from microcontroller P1 port as digital signals of the switch. By changing the number of contact closure control, we achieve steady flow output of different magnitude. By using closed-loop feedback control, we achieve constant monitoring of dust concentration and ensure it compliance with outlet concentration of national requirements. The results show that microcontroller control system has a strong anti-interference, high accuracy, ease of programming, etc. Used in the electrostatic precipitator, collection efficiency can be further improved.
