Abstract

A pollution control system for removing particle and gas phase pollutants in a waste airstream exhausted from commercial cooking operations may include a plurality of filters arranged within a housing for filtering particle and gas phase pollutants in the waste airstream. Various ones of the filters may be composed of a variety of different materials, and ozone may be provided within the housing to assist with removal of the pollutants. In some examples, a wash mechanism may be included to wash surfaces of a filter to remove grease therefrom. In some examples, the system may further include means to spray droplets (such as in a fog or mist form) into the waste airstream to condense a portion of gas phase pollutants into condensed particles.

Dependent claims

An air pollution control system for removing particle and gas phase pollutants in a waste airstream exhausted from commercial cooking operations, comprising:

a housing having an inlet and an outlet,
an exhaust fan attached to the outlet for drawing the waste airstream into the inlet and through the housing to the outlet and discharging to the outside atmosphere,
a plurality of filters arranged in adjacent spaced relation along the length of the housing between the inlet and outlet for filtering the particle and gas phase pollutants in the waste airstream,
a water droplet generation source adapted to spray water droplets into the inlet to mix with the incoming waste airstream, and
a wash mechanism arranged in the housing in facing relation to a first of the plurality of filters, the wash mechanism including a plurality of spray nozzles supplying a mix of heated water and detergent for periodically washing surfaces of the first filter to remove grease therefrom.
