IMPROVING THE EFFICIENCY OF ELECTROSTATIC PRECIPITATORS
RÉSUMÉ
This paper provides information on the achievements in development of gas cleaning. A critical analysis of functioning principle of electrostatic precipitators, which are currently being developed and operated, is conducted. The possibility of increasing the effectiveness of gas cleaning using unipolar voltage pulses has been analyzed. It has been found that a streamer mechanism of discharge or streamer shape of corona discharge is the case, when voltage pulses with over-voltage are used and electrostatic precipitators run. The most rational circuit for unipolar voltage pulses generation using low-voltage generators of periodic voltage pulses is identified. To separate space charges formed in the streamers' channel, it is proposed to use pulsating voltage with a direct component and a potential plane with corona needles-grounded plane electrode system. The analysis of transient process within feed circuit of discharge technological gaps has shown that cut-off pulse repetition frequency, in which stability of discharge current is ensured, depends on the parameters of feed circuit elements and the discharge gap capacitance. It was found that the use of corona discharge streamer form allows increasing the speed of the gas to be purified up to 8 m/s, and reducing the aerosol particles deposition zone to 1 m. The gas velocity is 1 m/s with a deposition zone of more than 27 m in an existing gas filling device (GFD) type electrostatic precipitator. When comparing these indicators, the energy intensity of the process decreases by more than 100 times, and the specific power of the gas flow purification process is 33 (W·s)/m3.
