Air purification device and method

摘要

The present invention is an air purification method and device. Due to the lower airflow resistance that the present invention induces, an exhaust fan or blower with motor of lower torque is adopted. Consequently, the whole air purification is operated at a lower noise level. Lower operational voltage is applicable for the high-voltage electrostatic precipitator device and provides a similar or superior performance and effectiveness for dust removal. The air purification device/system is designed with higher flexibility and of more compact in dimension and size. Dust is removed from the environment by a high voltage electrostatic precipitator. The airflow stream within a high-voltage electrostatic precipitator is such that the direction of the path of the airflow is changed at least twice.
