Solution Overview
Problem
Existing CIP units struggle to achieve satisfactory cleaning results for heavily contaminated equipment or plant parts, often requiring increased time and cleaning liquid volume, and lack environmental friendliness and efficiency.
Innovation Solution
A CIP unit with a high pressure circuit section that bypasses a balance tank, allowing the cleaning liquid to be pressurized above atmospheric pressure, enabling higher temperatures and reducing cleaning time and water usage, while maintaining control over flow rate and temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the amount of cleaning liquid or time is increased to clean heavily contaminated equipment, then cleaning effectiveness is improved, but environmental friendliness and efficiency deteriorate
Solution Approach 1:
The patent changes the pressure parameter of the cleaning liquid by introducing a high-pressure pump, increasing the pressure from atmospheric to above atmospheric pressure. This parameter change enables the cleaning liquid to penetrate heavily contaminated surfaces more effectively, achieving satisfactory cleaning results without increasing the volume of cleaning liquid required
Solution Approach 2:
The patent applies hydraulic principles by using a high-pressure pump to circulate the cleaning liquid through the equipment at elevated pressures. The system includes a high-pressure circuit with a pump, control valves, and pressure gauge to maintain and regulate the high pressure throughout the cleaning process, improving cleaning effectiveness while reducing liquid consumption
2Reliability
If the amount of cleaning liquid or time is increased to clean heavily contaminated equipment, then cleaning effectiveness is improved, but cleaning time efficiency deteriorates
Solution Approach 1:
By changing the pressure parameter to above atmospheric pressure, the cleaning liquid achieves better penetration and cleaning action on heavily contaminated surfaces. This allows the cleaning process to be completed in less time while maintaining or improving cleaning effectiveness, eliminating the need to extend cleaning duration
3Device complexity
If atmospheric pressure cleaning is used, then system simplicity is maintained, but cleaning effectiveness for heavy contamination deteriorates
Solution Approach 1:
The patent introduces a high-pressure pump and associated control components (control valves, pressure gauge) to create a high-pressure hydraulic system. This adds controlled complexity to the system, enabling effective cleaning of heavily contaminated equipment while maintaining manageable system operation through proper instrumentation and control
