Embodiment Construction

[0152] According to a preferred embodiment of the present invention, in Figure 4 A combined filter 26 and electrode unit 25 mounted together are shown in . In operation, the structure is surrounded on all sides by ventilation ducts, and the air flows from top to bottom according to the arrows in the diagram.

[0153] The electrodes 14 are arranged parallel to the air flow and covered with a suitable photocatalytic material such as TiO 2 . Electrode 14 is typically aluminum, although other metals or other conductive materials may be used. On these electrode plates, UV light sources 16 are positioned on both sides of the electrodes. These light sources 16 are typically LED (Light Emitting Diode) light sources assembled on a suitable substrate, in this case a longitudinal circuit board extending deep into the filter bag 15 . Typically, the light source element is as long as the electrode 14 . On the other hand, the electrodes 14 extend almost to the end of the filter bag 15...

Abstract

This publication discloses an electrostatic filter device (2), to be positioned in air ducts or ventilation channels, which electrostatic filter device (2) includes a charging unit (10), which chargesthe particles to be filtered into a first electric potential and arranged in the filter device (2) in the path of the air flow before filter elements (15), electrically conducting electrodes (14, 31)connected to a second electric potential different to the potential of the charged particles and set substantially parallel to the direction of the airflow, and bag shaped filter elements (15) positioned after the charging unit (10) in the path of the air flow. According to the invention each bag shaped filter element (15) has at least one designated UV- light source (6) and an element (14, 31) of photo catalytic material like TiO2.

Description

technical field [0001] The invention relates to an electrostatic filter arrangement comprising a gas and particle filter according to the preamble of claim 1 . Background technique [0002] Awareness of airborne impurities and their health hazards has increased dramatically in recent years. Research has shown that gaseous and particulate impurities are environmental exposure agents that significantly increase disease and health hazards. These problems are most acute in large cities, where emissions from traffic and energy production pollute the air. In addition to being a health hazard, impurities in the outdoor air can affect the corrosion and oxidation of materials. [0003] Attempts have been made to reduce the transfer of impurities from the exterior of buildings and vehicles to indoor air by filtering incoming air. Today, mainly only particulate filters are used to clean displacement air in residential, office and commercial buildings. Only in some special occasions...
