Wet-type electrostatic precipitator energy-saving measures (thyristor method)

The improved energy-saving control achieves high energy efficiency for the electric dust collector.

Our electric dust collector adopts constant voltage control to achieve high dust collection efficiency. In conventional power-saving control, sufficient energy-saving effects could not be obtained during operation with low gas load. However, we have successfully developed an improved power-saving control that captures the characteristics of the electric dust collector, significantly enhancing energy-saving effects compared to conventional methods. The improved power-saving control can also be implemented in newly installed or existing electric dust collectors using constant voltage control, so customers considering energy-saving solutions for new or existing electric dust collectors are encouraged to contact us.

basic information

In the conventional power-saving control, the output voltage was switched based on two thresholds: a high and a low point of exhaust gas load, which meant that when the exhaust gas load was low, sufficient power-saving effects could not be achieved. In the newly developed improved power-saving control, the output voltage is continuously adjusted according to load fluctuations, allowing for sufficient power-saving effects even with small load variations, significantly enhancing the power-saving effectiveness compared to the conventional method.

Applications/Examples of results

Purpose: Electric dust collector using constant voltage control Results: The energy-saving effect obtained varies depending on the scale of the electric dust collector and the specifications of the exhaust gas, so we will consider it according to various conditions.
