Dissolving Solid Substances in Water Using Recirculation Jets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dissolving solid chemical substances in water, such as calcium hypochlorite, often result in deposit formation due to incomplete dissolution, requiring frequent manual intervention and energy-intensive agitation, which increases operational costs and risks damage from corrosion and salt deposits.
Innovation Solution
A device with a cylindrical container, a charging chamber for solid substances, and a liquid-dispersing unit that directs water jets to dissolve the substances gradually, combined with a recirculation system that maintains continuous flow and agitation, reducing deposit formation by controlling water flow based on concentration levels and using a differential float valve to regulate water levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If mechanical agitators or nozzle agitators are used to keep chlorinated water in agitation, then deposit formation is reduced, but device complexity increases and energy consumption increases
Solution Approach 1:
The system uses the chlorinated water itself to agitate and dissolve solid substances through recirculation and jet injection, eliminating the need for external mechanical agitators or blowers. The water flow performs the agitation function that would otherwise require separate mechanical devices.
Solution Approach 2:
The invention employs hydraulic principles by using pressurized water jets to create agitation and promote dissolution. The recirculation system uses pump-driven water flow to maintain movement and prevent deposits, replacing mechanical agitation with hydraulic action.
2Object-generated harmful factors
If mechanical agitators or nozzle agitators are used to keep chlorinated water in agitation, then deposit formation is reduced, but energy consumption increases
Solution Approach 1:
The chlorinated water performs the agitation function itself through recirculation, eliminating the need for energy-intensive mechanical agitators. The system uses the water's own flow to prevent deposits and maintain dissolution.
Solution Approach 2:
The recirculation system maintains continuous water flow and agitation, ensuring constant dissolution and preventing deposits without the need for periodic high-energy mechanical intervention. The continuous low-energy pump operation replaces intermittent high-energy mechanical agitation.
3Ease of operation
If floats with immersed mechanisms are used to regulate water levels, then water level control is achieved, but reliability decreases due to corrosion and salt deposits
Solution Approach 1:
The float mechanism is extracted from the corrosive environment by positioning it above the liquid level. The float operates in air rather than being immersed in chlorinated water, eliminating exposure to corrosion and salt deposits while maintaining water level control functionality.
Solution Approach 2:
A rod or linkage acts as an intermediary between the float and the valve mechanism. The float moves in air and transmits motion through the intermediary to control the valve, isolating the float from direct contact with corrosive water while maintaining control function.
