Abstract:
A multi-function fluid treatment system (10) which can filter liquids or diffuse gases into liquids. To achieve filtration, the system (10) includes a housing (150) with multiple, closely-spaced filter cartridges (12, 14, 16) therein. The cartridges (12, 14, 16) are connected to a drive system (632) which rotates them in unison. Fluids to be filtered enter the housing (150) and surround the rotating cartridges (12, 14, 16). Cartridge rotation scrubs solids from the cartridges (12, 14, 16) and promotes fluid flow into the cartridges (12, 14, 16). Filtered fluids collected within the cartridges (12, 14, 16) thereafter exit the system (10). To achieve gas diffusion, the housing (150) is filled with a selected liquid (840). During cartridge rotation as discussed above, a gas (802) is introduced into the interior of each cartridge (12, 14, 16) which is constructed of a porous material. The gas (802) diffuses outwardly during cartridge rotation, causing substantial mixing of the gas (802) and fluid (840), with gas diffusion into the fluid (840). Cartridge rotation also prevents solids from accumulating thereon to achieve maximum gas delivery.
Abstract:
A high efficiency, self cleaning system for separating solid materials from liquids. The system includes a primary housing (150) having at least one inlet (163) and a plurality of cylindrical filter cartridges (12, 14, 16) therein which are directly adjacent to and in close proximity with each other. The lower end of each cartridge (12, 14, 16) is positioned on a spring biased bearing member, with the upper end having an opening therein. Positioned within the opening and connected to each cartridge is a tubular shaft attached to a pulley type motor drive system (632, 750). The drive system (632, 750) is used to rotate the cartridges (12, 14, 16) in a selected direction. In operation, fluids to be filtered enter the housing and come into direct contact with the cartridges (12, 14, 16). Rotation of the multiple cartridges (12, 14, 16) and close proximity of the cartridges (12, 14, 16) to each other creates fluid turbulence within the housing (150). This turbulence scrubs collected solids from the cartridges (12, 14, 16) and promotes fluid flow into the cartridges (12, 14, 16).
