Problems solved by technology

Some oil droplets that are not deposited on the inner wall of the exhaust system may be discharged into the atmosphere, causing air pollution
Other problems that may be caused include: shortened exhaust fan life cycle due to clogging of pollutants, unsanitary due to rapid accumulation of bacteria on the inner wall of the exhaust system; increased fire risk due to dry grease layer on the inner wall; inefficiency of the exhaust action causing work Ventilation problems in the premises
However, most share one or more characteristics: complex, bulky, expensive, inefficient and dangerous to use

Embodiment Construction

[0034] First refer to figure 1 , shows an air flow passage through the exhaust system, with air flowing in the direction of arrow 50 . The air passing in the direction of arrow 50 may contain contaminants such as oil droplets, dust, particulate matter and others. Air is drawn in the direction of arrow 50 when an exhaust fan (not shown) of the exhaust system operates.

[0035] The self-cleaning filter assembly 52 is arranged in the airflow channel of the exhaust system along the airflow direction 50 . Self-cleaning filter assemblies fit into brackets or slots on existing filter assemblies in existing exhaust systems. Existing baffle filters may be replaced with self-cleaning filter assemblies 52 . A traditional kitchen exhaust system can be replaced with an advanced grease removal kitchen exhaust system with minimal capital expenditure. Such as Figure 14 As shown, the self-cleaning filter assembly 52 may be installed in an existing bracket or slot in an existing exhaust s...

Abstract

The present invention provides a self cleaning filter assembly for use in an exhaust system, including: a casing for placement in the path of an air flow, the casing containing: a first filter; a second filter; a barrier for placement adjacent to the casing to prevent a cleaning fluid from dripping from the first filter and out from the casing; and a plurality of spray outlets for dispersion of fluid within the casing and onto the filters. The plurality of spray outlets create droplets of the cleaning fluid of a size able to combine with droplets of a contaminant to form combined droplets in the air flow and wherein the first filter and the second filter captures droplets of the contaminant and droplets from the spray outlets. A circulation system for use with the filter assembly is also disclosed.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200480010316.3, the application date is December 21, 2004, and the invention name is "self-cleaning filter assembly and circulation system". technical field [0002] The present invention relates to a self-cleaning filter assembly, in particular, but not exclusively, to a self-cleaning filter assembly for use in domestic and industrial exhaust systems for exhausting vapors, such as those produced during kitchen cooking and chemical processing steam. Background technique [0003] The use of exhaust systems to exhaust contaminated air from affected work areas is mandatory in many industries. For example, the manufacturing and chemical industries are such industries. [0004] Such exhaust systems are commonly used in industrial and commercial kitchens such as the food processing industry and hotels, where the use of oil to treat food is common as long as the food...
