A continuous water wash hood type ventilation system for installation over one or more cookers, wherein exhaust air is drawn into and passed through one or more hoods for scrubbing by a spray of recirculated solution, including a water-detergent combination, with each hood incorporating a canopy formed of a front, back, side and top walls, an exhaust outlet provided through the top wall, an exhaust chamber formed within the canopy by means of a series of arranged baffles, generally comprising an upper, intermediate, and lower baffle, all staggered, to adequately pass the exhaust gases through the canopy to achieve scrubbing and discharge, and for properly channelling the collection of the scrubbing solution within a basin for draining to a supply and recirculation reservoir. The recirculation unit of this invention includes its reservoir, a pump for recirculating the solution to the various spray heads embodied within the exhaust hoods, the reservoir holding the supply of water-detergent solution, and additional water may be added to the reservoir, to replenish any depleted stock, while further adding a quantity of detergent so as to maintain a specified concentration of the solution for use within the ventilating system; a drain may be provided for flushing all or part of the solution, and which accumulates grease and debris for collection of such impurities before the soiled water is discharged to the sewer system.

A continuous water wash hood type ventilating system for installation over one or more cookers, heaters, or the like, wherein the exhaust air drawn into and passing through one or more hoods is scrubbed by a spray of recirculated water, wherein each hood incorporating a canopy formed having a front, back, side, and top walls, an exhaust outlet incorporated through one of said walls, an exhaust chamber provided within the canopy and communicating with the outlet, a series of baffle means structured into the interior of the canopy at the entrance to the exhaust chamber and providing a circuitous path for movement of the exhaust air arising from the cooker, while also providing a channeling means for flow and collection of the sprayed water, and said baffle means including a series of vertically staggered and overlapping baffles, an upper baffle connecting with the back wall and extending forwardly and downwardly within the canopy, an intermediate baffle connecting with the canopy and extending rearwardly and downwardly beneath the arranged upper baffle, and a lower baffle connecting within the canopy and extending forwardly and upwardly beneath the intermediate baffle, said lower baffle shaped to form the said collection basin for accumulation of the sprayed air scrubbing water, and wherein said baffling means being disposed for effecting a cascading of the scrubbing water to provide a precooling of the exhaust gases before their passage through the sprayed water, a series of spray heads arranged the length of the canopy and within the exhaust chamber to form an aquatic shield therein during hood operations, said spray heads arranged within the canopy and above the baffle means and each provided for discharging a cone shaped spray of water for furnishing an aquatic shield throughout the exhaust chamber and through which the exhaust air must pass for scrubbing before exiting the canopy via the exhaust outlet, a collection basin operatively associated with the canopy and arranged downwardly of the baffle means for accumulation of the sprayed air scrubbing water, a drain connecting with the basin, a reservoir communicating with the drain for deposit and collection of the water, and a recirculation pump communicating with said reservoir for returning the wash water to the spray heads during functioning of the ventilating system.
