Large steel industry sintering machine electrostatic dust collector electrostatic precipitators are mainly
used to filter the dust produced by burning coal in power plants.
Its working principle is to use a high voltage electric field to charge the suspended particles in the flue
gas, and then separate and collect them by electrostatic action. When the flue gas enters the dust
collector, the dust particles in it are attracted by the charge and adhere to the inner wall of the dust
collector. After a period of time, these dust particles will automatically fall and collect. This electrostatic
precipitator can filter out up to 99% of the dust, thus protecting the environment. This is how electrostatic
precipitators work.
Large steel industry sintering machine electrostatic dust collector the main reason why electrostatic
precipitators need to be cleaned regularly is to ensure their continuous
and efficient operation. Electrostatic precipitator attracts and collects particles in the air through the action
of electric field in the process of work, so that they deposit on the electrode. Over time, a large amount of
dust and particulate matter will accumulate on the electrode, which will gradually affect the electric field
strength and reduce the dust removal efficiency. In addition, ash accumulation can cause a number of
problems, including equipment damage and safety hazards.
