Solution Overview

Problem

Existing electrolytic cells face inefficiencies due to solid material accumulation at cathodes, reduced dissolution rates, and interference from carbon dust, leading to decreased performance and increased resistance.

Innovation Solution

Feeding solid material and gas into the electrolytic cell close to the anode, with an inlet positioned within a specific distance relative to the anode, facilitates quicker dissolution and reduces accumulation at cathodes, utilizing inert gas to maintain a conducive atmosphere and turbulent mixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If solid material is fed into the electrolytic cell at conventional positions, then the material can be introduced into the cell, but solid material accumulates at cathodes and dissolution rates decrease

Engineering Contradiction:

Improvematerial throughputVSAvoiddissolution rate

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The solid material is fed into the electrolytic cell near the anode before it can reach the cathode, preventing accumulation at the cathode. This preliminary positioning of the material in the electrolyte near the anode allows it to dissolve before potentially interfering with cathode operations, thereby maintaining high dissolution rates and continuous productivity.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If solid material is fed into the electrolytic cell, then material processing can occur, but carbon dust interferes with the process and resistance increases

Engineering Contradiction:

Improveoperational efficiencyVSAvoidcarbon dust interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The harmful carbon dust is removed from the system by feeding solid material near the anode where carbon dust is generated and removed through the electrolysis process. The carbon dust is extracted from the electrolyte at the anode region, preventing it from accumulating and interfering with the overall electrolytic process, thereby maintaining operational efficiency and preventing resistance increases.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the inlet is positioned far from electrodes, then material feeding is simpler, but dissolution rates decrease and accumulation occurs

Engineering Contradiction:

Improveinlet positioningVSAvoiddissolution rate

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The inlet is positioned in a specific local region near the anode where the electrolyte conditions are optimal for dissolution. This localized positioning takes advantage of the electrochemical environment near the anode, including bubble-induced mixing and electrical field effects, to maximize dissolution rates while maintaining operational simplicity.

Inventive Principle:

Principle #3Local quality

4Productivity

If higher currents are applied to increase productivity, then material throughput increases, but solid material accumulation at cathodes worsens

Engineering Contradiction:

Improvematerial throughputVSAvoidsolid material accumulation

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

Solid material is fed near the anode where it dissolves into ions before reaching the cathode, preventing the accumulation of undissolved solid material at the cathode even at higher currents. This preliminary dissolution action ensures that the material is in ionic form and can be properly transported through the electrolyte without forming problematic accumulations.

Inventive Principle:

Principle #10Preliminary action
