Fluid Treatment Apparatus Upward Flow Medium Bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid treatment apparatuses face issues with treatment medium clogging, short service life, high usage amounts, pressure loss, and reduced water flow, especially in low water pressure regions, due to the compaction of treatment mediums which leads to decreased performance and frequent replacement needs.
Innovation Solution
The apparatus features a treatment chamber with a permeable wall where the fluid moves treatment mediums in a direction opposite to their natural movement, maintaining a medium bed layer that prevents compaction, reduces friction, and allows for easy removal of dirt and impurities, along with features like bed depth control plates and flow control flanges to enhance treatment performance and reduce pressure loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If treatment mediums are used in conventional fluid treatment apparatus, then treatment function is provided, but treatment mediums compact during service causing clogging and short service life
Solution Approach 1:
The patent inverts the conventional flow direction by making the fluid flow upward through the treatment mediums instead of downward. This upward flow counteracts the compaction caused by gravity and maintains the treatment mediums in a loose, expanded state, preventing clogging and extending service life while preserving the treatment function.
2Reliability
If treatment mediums adsorb dirt and impurities, then treatment performance is achieved, but resistance increases and water pressure is lost
Solution Approach 1:
By inverting the flow direction to upward flow, the patent prevents the compaction that leads to increased resistance and pressure loss. The treatment mediums remain expanded and loose, maintaining low resistance while continuing to adsorb dirt and impurities effectively, thus preserving both treatment performance and water pressure.
Solution Approach 2:
The upward flow continuously expands and fluidizes the treatment mediums, maintaining a consistent loose state throughout service. This continuous action prevents the progressive compaction that would otherwise occur, ensuring sustained low resistance and pressure loss while maintaining treatment performance.
3Reliability
If treatment mediums are compacted, then dirt capture capability is improved, but output water flow decreases
Solution Approach 1:
The upward flow direction inverts the conventional compaction mechanism. Instead of compacting the treatment mediums to improve dirt capture, the upward flow keeps them expanded and loose, maintaining high porosity and water flow capacity while still enabling effective dirt capture through the treatment medium's surface area and chemical properties.
4Ease of operation
If simple backwash operation is performed by reversing filter element, then disassembly is simplified, but dirt bonded on treatment medium surface is not effectively removed
Solution Approach 1:
The patent utilizes the upward flow direction during backwash to effectively lift and suspend the treatment mediums, causing them to collide and rub against each other. This mechanical action, combined with the reversed flow, effectively removes dirt bonded to the treatment medium surfaces, significantly improving cleaning effectiveness while maintaining operational simplicity.
Solution Approach 2:
The upward flow during backwash creates turbulent motion and mechanical vibration among the treatment mediums, enhancing the removal of bonded dirt through friction and collision. This mechanical action complements the flow reversal to achieve effective cleaning.
