Halogenating Process Resolving Sludge Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing halogenation devices for water, such as those used in swimming pools, suffer from contamination and clogging due to insoluble residues like lime sludge, which are not effectively prevented from entering the dosing system.
Innovation Solution
A method that allows sufficient settling time for sludge in the collecting basin before the halogenated solution is discharged, utilizing a controller to manage the flow and ensure that the solution is free from residues before transfer, incorporating a funnel-shaped bottom for efficient sedimentation and a cleaning mechanism to remove accumulated sludge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the outlet line is positioned close to the bottom of the collecting basin, then the discharge of halogenated water is efficient, but sludge and residues enter the dosing system causing contamination and clogging
Solution Approach 1:
The outlet line is segmented into multiple openings positioned at different heights above the basin bottom. This segmentation allows the system to draw water from multiple levels, ensuring efficient discharge while preventing sludge entry, as the lower openings are positioned above the sludge accumulation zone but below the water surface.
Solution Approach 2:
The outlet line acts as an intermediary structure between the collecting basin and dosing system. By positioning its openings at a specific height above the bottom, it mediates between the need for efficient water discharge and the need to prevent sludge contamination, allowing clear water to pass while blocking residues.
2Object-affected harmful factors
If the outlet line is positioned high above the bottom of the collecting basin, then sludge contamination is prevented, but the discharge of halogenated water becomes less efficient
Solution Approach 1:
The outlet line is divided into multiple openings distributed at different heights. This segmentation allows the system to maintain effective discharge by utilizing openings at optimal heights while preventing sludge contamination through the strategic positioning of lower openings above the sludge zone.
Solution Approach 2:
The outlet line transitions from a single-point discharge to a distributed multi-height discharge system. This dimensional change from vertical point to vertical distribution allows simultaneous achievement of contamination prevention and discharge efficiency by utilizing the vertical dimension strategically.
3Productivity
If water flows continuously through the collecting basin, then the dosing system operates without interruption, but sludge accumulates and settles in the basin
Solution Approach 1:
The system implements periodic action by controlling water flow to alternate between filling the collecting basin and allowing sludge settlement. During settlement phases, water flow is reduced or stopped, allowing sludge to settle. During discharge phases, water is drawn through the elevated outlet line, preventing sludge entry while maintaining continuous overall operation.
Solution Approach 2:
The outlet line is pre-positioned at an elevated height before operation begins. This preliminary configuration ensures that from the start, the system is capable of preventing sludge contamination while maintaining discharge efficiency, without requiring active control during operation.
4Object-generated harmful factors
If a jet of water is introduced at the bottom of the catch basin to keep water in motion, then sludge settling is prevented, but the water in the basin cannot be effectively discharged and contamination occurs
Solution Approach 1:
Instead of using bottom jets to prevent sludge settling, the invention inverts the approach by using elevated outlet openings to prevent sludge entry. The system accepts that sludge will settle but prevents contamination by drawing water from above the sludge zone, eliminating the need for anti-settling measures.
Solution Approach 2:
The invention converts the harmful effect of sludge settling into a beneficial separation mechanism. By allowing sludge to settle naturally and positioning outlet openings above the sludge zone, the system uses gravity-driven separation to its advantage, achieving both sludge containment and clean water discharge without requiring active anti-settling measures.
