Abstract
A grease extractor apparatus having a housing, a hood, a first chamber connecting with air and grease vapors entrained by said hood, a cold water spray nozzle system and a hot water wash system associated with said chamber, a sump at the bottom of said chamber for collecting solidified grease vapors, a second chamber connecting with said first chamber and having additional wash nozzles incorporated therewith, a third chamber for having turbulent flow therein and connected with said second chamber, a duct leading from the third chamber to an expansion chamber the expansion chamber having an airflow baffle and third wash nozzles incorporated therewith, and an exhaust duct from the expansion chamber connected to a suction fan and a fire damper means therein.
Claims13
A ventilating system for drawing air from above cooking ranges and the like, comprising;
- a vertically oriented, upstanding housing adapted for mounting above a cooking range, a hood member secured to the housing for collecting contaminated air for passage through the housing, an entry chamber having an opening at an angle to the vertical arranged on the housing and adjacent the hood member, a plurality of baffle plates within the housing and arranged transversely of the air flowing through said housing, nozzle means within the chamber for imparting a spray of cold water across substantially the width of the chamber to extract contaminant materials entrained in the air, additional nozzle means disposed within the entry chamber for imparting a spray of hot wash liquid to said chamber and the baffle plates arranged therein, sump means at the bottom of said chamber for collecting and removing excess liquid and contaminant materials collected at the bottom of the chamber, an expansion chamber within the housing arranged above the forementioned structure to receive the flow of air and to permit an expansion and slowing of movement thereof, an exhaust duct communicating with the expansion chamber for exhausting the air after cleaning thereof, an easily removable central manifold structure, and said nozzle means and additional means are provided upon said central manifold structure for complete assembly and removal of the entire arrangement as an integral unit.
A ventilating system for drawing air from above cooking ranges and the like, comprising;
- a vertically oriented, upstanding housing adapted for mounting above a cooking range, a hood member secured to the housing for collecting contaminated air for passage through the housing, an entry chamber having an opening at an angle to the vertical arranged on the housing and adjacent the hood member, a plurality of baffle means within the housing and arranged transversely of the air flowing through said housing, nozzle means within the chamber for imparting a spray of water across substantially the width of the chamber to extract contaminant materials entrained in the air, and sump means at the bottom of said chamber for collecting and removing excess liquid and contaminant materials collected at the bottom of the chamber, and an expansion chamber within the housing and above the forementioned structure to receive the flow of air therewithin and to permit an expansion and slowing of movement thereof, and an exhaust duct communicating with the expansion chamber for exhausing the air after cleaning thereof, an additional nozzle means disposed within the entry chamber for imparting a spray of wash liquid to said chamber and the baffles arranged therein, and an interior baffle being provided for separating the contaminant sump into two portions with the first portion being adjacent the flow of exhaust air throughout the apparatus for creating a blowing effect upon the said surface to cause contaminant particles floating thereon to be pushed backwardly into the second part for exhaust out a sump overflow, the lower edge of said interior baffle almost touching the water surface in the sump so that the second part is not in the flow of air through the first portion.
