Filter Housing Self-Cleaning Nozzle System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial filtration systems face inefficiencies in cleaning filter cartridges due to accumulated debris and particles, which can lead to reduced filter efficiency and require manual replacement, and existing cleaning methods, such as backwash, may not effectively remove particulate material, especially when dealing with hazardous fluids.
Innovation Solution
A self-cleaning system integrated with the filter housing, featuring a movable wash nozzle and a gas injection mechanism that uses high-pressure gas to dislodge debris and a purge pipe to drain accumulated materials, allowing for efficient cleaning without opening the filter housing, and a processor-controlled process to manage the cleaning stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning by removing the cartridge is used, then the filter surface can be cleaned, but the filtration operation must be shut down and the housing must be opened
Solution Approach 1:
The filter housing is equipped with an integrated cleaning system that automatically cleans the filter cartridge while it remains in place. The system includes a movable nozzle that travels along the filter surface, powered by the existing fluid flow through the housing, eliminating the need for manual intervention and shutdown.
Solution Approach 2:
The cleaning function is merged with the filtration housing itself, rather than being a separate offline process. The housing contains both the filtration media and the cleaning mechanism, allowing simultaneous operation of filtration and cleaning functions.
2Productivity
If backwash procedure is used, then fluid flow can wash accumulated debris, but the flow may not be strong enough to remove aggregated particulate material
Solution Approach 1:
The system utilizes high-velocity fluid jets directed at the filter surface to provide intense localized washing force. The nozzle system converts the bulk fluid flow into concentrated high-velocity streams that can effectively remove aggregated particulate material without requiring system shutdown.
Solution Approach 2:
Instead of applying uniform backwash flow across the entire filter surface, the system concentrates the washing action at specific locations through movable nozzles that can be positioned to target areas with accumulated debris, maximizing the effectiveness of the washing force.
3Ease of operation
If external spraying device is used to move along filter surface, then cleaning can be performed, but liquid/gas escape may occur causing health and environmental concern
Solution Approach 1:
The cleaning system is integrated within the filter housing structure, with the nozzle system contained inside the sealed housing. This eliminates the need for external spraying devices that would require opening the housing, thereby preventing escape of hazardous liquids or gases during the cleaning operation.
4Ease of operation
If filter cartridge is removed for cleaning, then the surface can be accessed, but the housing must be opened and operation shut down
Solution Approach 1:
The cleaning system is integrated within the filter housing structure, with the nozzle system contained inside the sealed housing. This eliminates the need for external spraying devices that would require opening the housing, thereby preventing escape of hazardous liquids or gases during the cleaning operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables effective self-cleaning of filter cartridges within the housing, reducing downtime and preventing hazardous material escape, maintaining filtration efficiency and ensuring a safer, greener environment by integrating the cleaning process with backwash operations and using high-pressure fluid and gas to dislodge and remove particulate matter.
Implementation Method 1
introducing a pressurized gas that causes turbulence inside the filter housing to 'bubble off' (dislodge) the accumulated solids on the filter
Implementation Method 2
A gas injection inlet is also provided for introducing a pressurized gas that causes turbulence inside the filter housing
Implementation Method 3
a wash nozzle integrated with the filter housing... connected to a source of wash fluid through a wash pipe
Implementation Method 4
Another often performed filter cleaning procedure is called 'backwash,' where the fluid flow within the filter housing is reversed, and the accumulated debris and particles can be washed by the fluid and drained

AI summary
The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.
