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

[0033] 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.

[0034] 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 an exhaust system, comprising: a housing positioned in an airflow channel, the housing comprising: a first filter; a second filter; a filter adjacent to the housing a baffle that prevents cleaning fluid from dripping from the first filter and out of the housing; and a number of spray nozzles that distribute the fluid within the housing and onto the filter. The plurality of injection nozzles generate cleaning fluid droplets of a certain size capable of combining with pollutant droplets to form combined droplets in the gas flow, wherein the first filter and the second filter capture the pollutant droplets and the particles emitted from the injection nozzles. droplet. A circulation system for a filter assembly is also disclosed.

Description

technical field [0001] 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 [0002] 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. [0003] 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 is cooked. In this way, cooking produces fumes containing oil droplets. [0004] The filters installed in this type of exhaust system usually consist of a steel mesh designed to catch most of the oil droplets. Such filters may be located in the exhaust ho...
