Appl. No.:

12/622070

Inventors:

Russell Robison - Yamhill OR, US
Bruce Lukens - Newberg OR, US

Assignee:

ITW Food Equipment Group LLC - Glenview IL

International Classification:

F24C 15/20

US Classification:

126299R, 126299 F, 126300, 454 56

Abstract:

An exhaust system includes a hood structure having one or more of (i) an exhaust flow infeed surface extending downward from a lower end of the filter unit that helps to feed the thermal plume toward the filter unit, (ii) a bypass flow transition surface extending upward from the upper end of the filter unit and then forward to aid bypass flow in circulating back toward the filter aperture and (iii) a front wall structure that includes a downwardly extending wall portion with a chamfered and/or curved transition portion at its lower end and a rearwardly extending wall portion.

Inventors:

Russell Robison - Yamhill OR, US

International Classification:

B03C 3/74
B08B 3/04

US Classification:

134042000, 096043000

Abstract:

An electrostatic precipitator wash system includes a plurality of fluidic oscillator nozzles through which wash solution is directed at the electrostatic cell of the electrostatic precipitator. The nozzles are provided in a manifold rotatable about an axis of the manifold. The manifold is rotated through an arc of about 90 while emitting wash solution toward the cell in an oscillating stream of drops.

Russell Robison - Yamhill OR, US

International Classification:

F24C 15/20
B65D 69/00
G21G 5/00

US Classification:

126299 D, 206573, 2504921

Abstract:

A ventilator assembly for removing contaminants in cooking exhaust includes a hood portion having a hood plenum, and a duct portion in fluid communication with the hood portion, where the duct portion has an inside cross-sectional area that is less than half of an average inside cross-sectional area of the hoodplenum. A fan is in fluid communication with the duct portion for drawing the cooking exhaust through the hood portion to the duct portion. At least one ultra-violet lamp is disposed in the duct portion, where the ultra-violet radiation from the lamp reacts with the cooking exhaust to generate ozone for oxidizing contaminants in the cooking exhaust.

International Classification:

B08B 15/02

US Classification:

454 67

Abstract:

A ventilator assembly for removing contaminants in cooking exhaust includes a hood portion having a hood plenum and an exhaust portion downstream of and in fluid communication with the hood plenum. An electro-static precipitator is disposed in the hood plenum or the exhaust portion, and at least one ultra-violet lamp is disposed upstream of the electro-static precipitator for cleaning the electro-static precipitator. The ultra-violet radiation reacts with the cooking exhaust and removes collected contaminants from an electro-static cell of the electro-static precipitator.
