Abstract
A method is provided for preventing microbial growth on the collector plates (42) of an electronic air cleaner (10) by directing germicidal light, advantageously ultraviolet light, upon the surface of the collector plates (42) and the particulate material deposited thereon. At least one germicidal lamp (50) is disposed to irradiate ultraviolet light upon the collector plates (42) to destroy microbes that might be growing on the particulate material collected on the plates (42).
Claims2
A method for preventing microbial growth in an electronic air cleaner having an electrostatic precipitator cell including a plurality of collector plates arrayed in parallel spaced relationship and disposed within a gas flow passage defined within a housing and extending between an inlet to the housing and an outlet to the housing, comprising:
- disposing at least one lamp for emitting germicidal light within the housing either upstream or downstream of the array of collector plates;
- aligning said at least one lamp parallel to the array of collector plates;
- and
- providing at least one reflector in operative association with said at least one lamp for directing germicidal light emitted from said at least one germicidal lamp to irradiate upon said collecting plates at an angle of incidence.
