Abstract
A housing for purifying an air flow moving through it provides a reception space for receiving the air flow. The air is treated with mechanical filtration of particles larger than approximately 2 micron, ionizing with energetic ions, exposure to ultraviolet light radiation, and electrostatic precipitation of particles in the air inflow. The ionizing and UV bombardment of the air inflow occur simultaneously.
Claims13
An air purification apparatus comprising:
- a housing providing therein, a reception space for receiving an air inflow drawn into the reception space;
- a means for mechanical filtration and extraction of particles larger than approximately 2 micron in the air inflow, a means for ionizing of the air inflow with energetic ions;
- a means for bombardment of the air inflow with ultraviolet light radiation;
- and a means for electrostatic precipitation of particles in the air inflow;
- the ionizing means positioned integrally with the ultraviolet light radiation bombardment means.
2 more elements
An air purification method comprising the steps of:
- drawing an air inflow into a reception space of a housing;
- filtering particles larger than approximately 2 micron in the air inflow, ionizing the air inflow with energetic ions while simultaneously bombarding the air inflow with ultraviolet light radiation within an aperture of a closed loop ultraviolet lamp;
- and capturing particles from the air inflow using an electrostatic precipitator.
