Solution Overview
Problem
Cartridge filters in industrial operations face issues with particulate matter accumulation leading to clogging, reduced effectiveness, and costly downtime, as well as the challenge of recovering valuable particulate matter during filtration processes.
Innovation Solution
A method and apparatus that control the flow rate and use compressed air to dislodge particulate matter from cartridge filters, allowing it to settle and be collected, maintaining filter permeability and enabling the reuse or recovery of particulate matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cartridge filters are used to clean fluid in industrial operations, then particulate matter is removed from the fluid, but a non-porous filter cake accumulates around the exterior surface of the cartridge filter, reducing flow rate and effectiveness
Solution Approach 1:
The patent reverses the conventional filtration approach by using an inside-out cartridge filter where fluid flows from the interior to the exterior of the filter media. This inversion prevents particulate matter from accumulating on the exterior surface, eliminating the formation of non-porous filter cake that blocks flow in conventional outside-in filters.
Solution Approach 2:
The patent changes the flow direction parameter from the conventional outside-in flow to an inside-out flow through the filter media. This parameter change fundamentally alters how particulate matter interacts with the filter surface, preventing cake formation on the exterior while maintaining filtration effectiveness.
2Productivity
If cartridge filters operate with high flow rates to maintain productivity, then fluid processing efficiency is improved, but particulate matter penetrates into the filter media and accumulates, causing clogging and requiring frequent replacement
Solution Approach 1:
By inverting the flow direction to inside-out, the patent prevents particulate matter from penetrating deep into the filter media and accumulating. Particles are captured on the interior surface where they can be more easily removed, extending filter service life while maintaining high flow rates.
Solution Approach 2:
The patent enables easier removal and recovery of captured particulate matter from the interior surface of the filter. This allows for extended filter life through cleaning and regeneration, or efficient recovery of valuable particles, reducing the frequency of filter replacement.
3Reliability
If cartridge filters are cleaned or replaced frequently to maintain filtration effectiveness, then filter performance is preserved, but considerable downtime occurs during cleaning or replacement operations
Solution Approach 1:
The inside-out filter design allows for easier cleaning and recovery of particulate matter from the interior surface. The filter can be cleaned in-place or regenerated more efficiently, reducing the frequency and duration of maintenance shutdowns while maintaining filtration effectiveness.
Solution Approach 2:
The filter design enables self-cleaning capabilities or easier regeneration processes, reducing the need for manual intervention and extensive downtime for maintenance operations.
4Ease of manufacture
If conventional cartridge filters are used, then disposable filtering is achieved, but valuable particulate matter cannot be easily recovered and the filters must be replaced frequently
Solution Approach 1:
The inside-out filter design facilitates the recovery of valuable particulate matter captured during filtration. The particles accumulate on the interior surface in a manner that allows for efficient collection and recovery, converting what would be waste into a recoverable resource.
Solution Approach 2:
By changing the flow direction parameter to inside-out, the patent alters the particulate matter distribution pattern, concentrating captured particles on the interior surface where they are accessible for recovery operations, rather than being dispersed throughout the filter media or on the exterior surface.

Function Achieved in This Case
This approach extends the life of cartridge filters, reduces downtime, and allows for the efficient recovery of valuable particulate matter by preventing non-porous filter cake formation and maintaining fluid flow rates, while enabling the collection and reuse of particulate matter.
Implementation Method 1
cleaning the at least one cartridge filter by introducing compressed air into the filter housing to dislodge the particulate matter deposited on the cartridge filter
Implementation Method 2
the dislodged particulate matter accumulates within the filter housing

AI summary
Method and apparatus are provided for treating and removing particulate matter from fluid or treating and removing fluid from a recoverable particulate matter from fluid circulating into, through and out of an industrial operation, and for washing a disposable cartridge filter used therein. The influent fluid is maintained at a flow rate such that the differential pressure across the cartridge filter is no greater than 10 psi to prevent the buildup of non-porous filter cake. A pressure detecting mechanism and method is also provided to detect the amount of deposited particulate matter inside the cartridge filter, so that an operator can determine whether the cartridge filter should be taken out to remove or recycle the deposited particulate matter.
