Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrolytic cell systems for producing oxidants face inefficiencies due to the need for expensive pumps to precisely meter brine, which can lead to energy losses and inconsistent oxidant production, especially as carbonate scale builds up, requiring constant adjustments in voltage or amperage to maintain efficiency.
Innovation Solution
A vacuum venturi system is used to meter saturated brine into the electrolytic cell, employing a venturi injector and variable control valves to maintain the correct conductivity of the electrolyte, eliminating the need for expensive pumps and allowing for simpler, more reliable operation by adjusting brine flow based on monitored amperage levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive pumps are used to precisely meter brine, then brine flow control precision is improved, but system cost and complexity increase
Solution Approach 1:
The patent replaces mechanical pump-based brine metering systems with an electrolytic cell that uses electrical current to directly control brine generation and flow. The electrolytic cell converts electrical energy into chemical reactions that produce bromine and control brine flow rate through amperage regulation, eliminating the need for mechanical pumps and associated precision metering mechanisms.
Solution Approach 2:
The electrolytic cell generates brine on-demand through electrochemical reactions, using the brine it produces as the electrolyte for subsequent reactions. This self-contained system eliminates the need for external brine storage tanks, pumps, and complex flow control mechanisms, as the cell autonomously regulates brine production and flow based on electrical input.
2Measurement precision
If pumps are used to meter brine, then brine flow control is improved, but energy consumption increases
Solution Approach 1:
The patent replaces energy-intensive mechanical pump systems with an electrolytic cell that uses controlled electrical current to generate and meter brine. The electrical energy required to drive the electrochemical reactions is more efficiently converted into useful brine production compared to the mechanical energy required to pump and meter brine through complex valve and pump systems.
Solution Approach 2:
The electrolytic cell autonomously regulates brine production and flow rate through electrical control, eliminating the continuous energy consumption associated with pump operation. The system only consumes energy when brine is needed, and the amount of energy consumed is directly proportional to the brine production rate, providing more efficient energy utilization.
3Stability of the object's composition
If voltage or amperage adjustments are made to maintain efficiency as scale builds up, then oxidant production consistency is improved, but operational complexity increases
Solution Approach 1:
The patent incorporates a control system that monitors oxidant production and automatically adjusts electrical parameters (voltage, amperage) to maintain consistent oxidant output despite carbonate scale buildup on electrodes. The feedback mechanism detects changes in cell resistance and production rate, then automatically compensates by adjusting electrical input, eliminating the need for manual interventions and complex operational procedures.
4Measurement precision
If pumps with moving parts are used, then brine metering capability is improved, but reliability decreases due to wear and tear
Solution Approach 1:
The patent replaces mechanical pump systems with moving parts that are subject to wear, seal failures, and maintenance requirements with a stationary electrolytic cell system. The electrolytic cell uses electrochemical reactions to generate and meter brine without mechanical moving parts, significantly improving system reliability and eliminating maintenance associated with pump components.
