Backwashing fluid filtering system

Abstract

The system of the present disclosure enables a filter cartridge having an array of filter media tubes to be remotely selectively back flushed during service by sequentially flushing the tubes with the rotary valving element to permit removal of trapped filtered material in service without disrupting the filtering flow in the balance of the filter array.

Description

Background technique [0001] The present invention relates to a series connection type fluid filtration system for filtering pressurized fluid flowing in a treatment system. Typically, filters for in-line filtration of fluids employ a pressure vessel with a detachable cover having an inlet adapted to be connected to a source of pressurized fluid and an outlet adapted to be connected to a fluid discharge conduit for fluid in the fluid Handle continuous flow in the system. Filtration systems of this type are also known to employ removable assemblies of filter media elements which can be easily removed from the pressure vessel when the cover is opened. However, it is an operational desire to minimize the need to shut down and depressurize the fluid flow system in order to uncap the pressure vessel and replace the fluid filter cartridge. [0002] The filter cartridge may employ a set of tubular filter members disposed between end caps or tube sheets for positioning in the pressur...

AI Technical Summary

Problems solved by technology

At work, it has been experienced that filtered foreign matter, especially particulate matter, quickly accumulates on the inner surface of the filter media tube and causes clogging of parts of the filter, thus reducing the flow rate through the filter which affects fluid system operation
