Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas generation and processing apparatuses face issues with gas purity and malfunction due to inadequate pressure control, leading to fluctuations in pressure and reduced operational efficiency of compressors.
Innovation Solution
A pressure control apparatus comprising a body portion with a fluid inlet and outlet, a pressure sensor module, a valve module, and a control module that automatically adjusts the fluid pressure by measuring and controlling back pressure between the compressor and gas separator, using a solenoid valve for proportional pressure relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic pressure control is implemented using a pressure sensor module, control module, and solenoid valve, then pressure stability and gas purity are improved, but device complexity increases
Solution Approach 1:
The pressure control apparatus employs a feedback mechanism where the pressure sensor module continuously monitors the pressure of compressed gas and sends signals to the control module. The control module automatically activates the solenoid valve to relieve pressure when thresholds are exceeded, creating a closed-loop system that maintains pressure stability without manual intervention.
Solution Approach 2:
The system is designed to be self-regulating, where the control module autonomously decides when to activate the solenoid valve based on pressure sensor readings. This self-service capability eliminates the need for external monitoring or manual pressure adjustment, improving reliability while the automation manages the added complexity.
2Reliability
If back pressure control is implemented between compressor and gas separator, then gas purity is improved, but energy consumption increases
Solution Approach 1:
The solenoid valve is designed to activate only when pressure exceeds predetermined thresholds, providing partial relief rather than continuous operation. This partial action approach maintains gas purity by controlling back pressure only when necessary, while minimizing energy consumption by keeping the valve closed during normal operating conditions.
