Benefits of technology

The present invention is an improved regenerative media filter structure and associated method of manufacturing such a filter. The invention solves problems associated with current regenerative media filters by achieving high fluid flows without being affected by turbulence. The invention filters a greater volume of fluid in a smaller footprint, resulting in lower installation costs. The invention also includes a bridging element or member that forms a closed interstitial space which allows for high levels of regenerative media filtration while minimizing the filter size. The invention includes a honeycomb pattern with at least three bridging elements, each containing a coil spring that helps prevent differential pressure collapse as the filter element becomes loaded with filtrate. The invention ensures a taught sheath and prevents pump head pressure reduction, resulting in significant energy savings.

Problems solved by technology

The field of regenerative media filters suffers from inefficient placement of the filtration elements relative to each other.
The tank geometry is therefore overly sized and inefficient.
Furthermore, this inefficient placement makes the filter susceptible to turbulence, which negatively affects the filtration efficiency.

Embodiment Construction

[0078]In accordance with the present invention the regenerative media filter is constructed to optimize the overall size of the filter per unit of fluid filtered and achieves this by optimizing multiple variables simultaneously, Refer in particular to FIG. 2 that illustrates a regenerative media filter in accordance with the present invention indicated generally at 32. These variables include, among possible other variables, the diameter of the filter elements 31; the planar spacing of the elements 31; the volume of regenerative media 33 that is deposited on the outer surface 40 of the filter elements 31; the resultant interstitial free space S (refer, for example, to the embodiment shown in FIG. 25) when the filter elements 31 are coated with the filtration media 33; the shell diameter of the filter housing 34; the height and volume of the inlet zone 35; the height and volume of the buffer zone 36; and the height and volume of the filtration zone 37 of the regenerative media filte...

Abstract

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.

Description

RELATED CASES[0001]This application is a continuation-in-part (CIP) of U.S. Ser. No. 16 / 047,437 filed Jul. 27, 2018 and which claims priority under 35 U.S.C. § 119(e) to commonly owned and co-pending U.S. Provisional Patent Application Nos 62 / 647,006 filed Mar. 23, 2018 and 62 / 655,468 which was filed on Apr. 10, 2018, and each of which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates in general to improvements in subcomponents that form a regenerative media filter; particularly subcomponents within the gas and liquid filtration housing of the regenerative media filter. More particularly, the present invention relates to an improvement and optimization of the construction of interdependent components of the regenerative media filter. Even more particularly the present invention relates to the relative proximity and sizing of individual filter elements or components including the provision, in one embodiment, of a monolithic...
