Dry electrostatic precipitator is a dust collector that removes ash from flue gas and discharges it in dry state. It releases a high-intensity electric field through electrodes. Under the action of the electric field force, the charged dust is collected by the cathode and anode devices. The anode plate adopts parallel suspended metal plates, while the cathode can be top-mounted or side-mounted according to the actual situation of the project.

[0003] Traditional dry electrostatic precipitators can only monitor pollutant emissions and operating parameters, but cannot monitor and characterize CO2 emissions, which is not conducive to energy conservation and carbon reduction of pollution reduction equipment. This paper proposes an online accounting system and method for characterizing CO2 consumption during operation of dry electrostatic precipitators. [Summary of the invention]
