Abstract
The present invention relates to a fume purification system used in conjunction with food cooking equipment. The fumes which are generated during cooking pass through a plurality of filter balls washed by an oxidizing liquid which removes the greasy contaminants from the said fumes. A cooling coil is also used in conjunction with the filter balls to accelerate the condensation of the fumes. If required, a charcoal filter is placed before the purified air is returned to the atmosphere or recirculated in the system.
Claims16
A purification system for removing contaminants including particles and gases from fumes generated from a cooking area, said system comprising:
- a container having an upper portion and a lower portion, said container including an inlet in said lower portion and an outlet in said upper portion;
- a plurality of stationary filter elements disposed in said container;
- means for cooling said filter elements, said cooling means used to increase the condensation of said fumes;
- means for holding said filter elements, said holding means used to keep said filter elements at a certain distance from said inlet of said container;
- means for cleaning and wetting said filter elements, a portion of said filter elements being disposed above said cleaning and wetting means;
- means for collecting liquid, contaminant particles, and condensed gases, said collecting means disposed in said lower portion of said container;
- and,
- means for inducing negative pressure, said inducing means connected to said outlet of said container.
A purification system according to claim 17 wherein said cleaning and wetting means includes an oxidizing liquid and means for circulating this liquid over said filter elements.
A purification system for removing contaminants including particles and gases from the fumes generated from a cooking area, said system comprising:
- a container having an upper portion and a lower portion, said container comprises an inlet in said lower portion and an outlet in said upper portion;
- a plurality of stationary spherical glass balls disposed in said container;
- means for cooling said glass balls, said cooling means used to inrease the condensation of said fumes;
- means for holding said glass balls, said holding means used to keep said balls at a certain distance from said inlet of said container;
- means for cleaning and wetting said glass balls, a portion of said cleaning and wettingmeans disposed in said lower portion of said container, said cleaning and wetting means includes an oxidizing liquid;
- means for collecting liquid, contaminant particles, and condensed gases, said collecting means disposed in said lower portion of said container;
- means for inducing negative pressure, said inducing means connected to said outlet of said container;
- wherein the cooling means comprises a refrigeration coil which surrounds the outside surface of said container;
- a hood disposed over said cooking area to collect said fuels and said container inlet and outlet are connected to said hook in order to form a closed circuit system;
- a charcoal cartridge is placed just after the negative pressure inducing means, a plate is disposed above said container inlet, in order to prevent the oxidizing liquid from entering into said inlet, the contaminant particles and condensed gases collecting means includes a "t" shape inlet located in the lower portion of said container and a reservoir is connected to said "t" inlet.
