Description

technical field [0001] The monitoring and evaluation system of the operating efficiency of the electrostatic precipitator of the present invention specifically relates to a system for real-time on-line monitoring of the working condition of the electrostatic precipitator and evaluation of its working efficiency level. Background technique [0002] The electrostatic precipitator uses a high-voltage electric field to ionize the flue gas, so that the charged dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, called discharge electrodes, and the positive electrode is made of metal plates with different geometric shapes, called dust collection electrodes. The dust removal effect of this dust collector is very good, but the performance of the electrostatic precipitator is affected by three factors, such as the nature of the dust, the structure of the equipmen...

AI Technical Summary

Problems solved by technology

If the specific resistance is too low, it is difficult for dust particles to remain on the dust collecting electrode, causing them to return to the airflow

If the specific resistance is too high, the charge of the dust particles reaching the dust collection electrode is not easy to release, and the voltage gradient formed between the dust layers will cause local breakdown and discharge, which will cause the dust removal efficiency to decrease

Because people cannot intuitively observe the situation in the high-voltage electric field, it seriously affects the operating efficiency of the dust collector

There is currently no relevant technology to monitor and evaluate its work efficiency level
