摘要： A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path. The filter elements are disposed in an monolithic array. An inlet port arrangement is disposed at the filter housing leading to the inlet zone and is constructed and arranged to direct the fluid path into the filter housing in a manner so as to maintain a controlled turbulence at the inlet zone. The inlet port arrangement comprises a pair of inlet ports that are arranged in juxtaposition at the inlet zone and each having one end where the fluid flow enters. Embodiments that are considered as falling under the scope of the present invention include 1. Single inlet/two or more outlets; 2. Two or more inlets/single outlet, or 3. Two or more inlets and two or more outlets.

摘要： A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an array and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

摘要： A screening apparatus that includes a strainer element used for the purpose of retaining particulate while permitting the passage of a liquid through the strainer element, a support structure for the strainer element to enable rotation of the strainer element between opposed 180 degree positions, and a control member coupled with the strainer element for controlling the rotation of the strainer element. The strainer element, in both opposed positions thereof impedes any particulate while permitting the passage of a liquid. The control member is constructed so that, in a first state thereof, the rotation of the strainer element is periodically controlled to rotate the strainer element between said opposed 180 degree positions, and in a second state thereof, inhibits rotation of the strainer element.

摘要： A method of cleaning a regenerative filter having a filter housing having inlet and outlet zones, a fluid path provided between the inlet and outlet zones, and a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path, the method comprising draining all fluids from the filter housing, refilling the filter housing with fluid to an optimum level, and initiating a cleaning sequence of the filter housing with the fluid at the optimum level. The cleaning sequence can comprise agitating the tube sheet, initiating a pump to effectively air scour for a first predetermined amount of time, dwelling for a second predetermined amount of time, and repeating the agitating, initiating, and dwelling until a third predetermined amount of time is complete.

摘要： A heat exchanger that is constructed with a heat exchanger shell having inlet and outlet plenums and fluid inlet and outlet ports, and a tube sheet construction disposed in the heat exchanger shell. The tube sheet construction includes at least two separate tube sheets and a plurality of tubes that extend between the separate tube sheets. Each tube sheet includes at least two planar tube sheet segments and an interstitial layer disposed between the at least two tube sheet segments, and at least one sensor element supported by each of the interstitial layers. A control monitor controls flow through the shell by a feedback control from the sensor to an inlet control valve and/or a stimulus device excites the media layer.
