Abstract
A method for air purification from dust includes electrically charging dust by air ionization; and collecting the charged dust by an electric field force, performed in a common airflow while changing the direction of the airflow at least once by an angle of more than 135°.
Claims6
A method for air purification from dust comprising:
- electrically charging dust by means of air ionization;
- and
- collecting the charged dust by means of an electric field force, performed in a common airflow,
- wherein the direction of the airflow is changed at least twice by an angle of more than 135°, once between the step of electrically charging the dust and the step of collecting the charged dust and once during the step of collecting the charged dust, where dust is influenced by the electric field.
1 more element
An electrostatic filter comprising:
- a dust charging device, a dust collector having at least one section, high voltage power supplies for applying an electric field through which an airflow is provided, which includes at least two direction-changing devices for changing the direction of the airflow passing through by an angle of more than 135°, one direction changing device located between the dust charging device and the dust collector and one direction-changing device located within the dust collector where dust is influenced by the electric field.
