Two-Stage Gas Solution Supply for High Concentration and Stable Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone water producing devices struggle to achieve high concentrations of ozone water due to limited pressure in the gas-liquid separator and fluctuations in delivery pressure, especially when using air-driven pumps.
Innovation Solution
The gas solution supply device incorporates a first and second gas-liquid separator, an intermediate line with a pressure booster pump, and a gas dissolving unit to increase pressure and concentration of the gas solution, while the second gas-liquid separator acts as a damper to stabilize delivery pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single gas-liquid separator and downstream pump configuration is used, then the device structure is simple, but the pressure in the gas-liquid separator cannot be increased and high concentration of gas solution cannot be achieved
Solution Approach 1:
The gas-liquid separation system is divided into two separate gas-liquid separators (first and second) arranged in series. The first gas-liquid separator handles initial separation at lower pressure, while the second gas-liquid separator performs final separation after pressure boosting. This segmentation allows each separator to operate optimally at different pressure stages, enabling high concentration gas solution while maintaining manageable structural complexity through modular design.
Solution Approach 2:
A pressure booster pump is introduced between the two gas-liquid separators to pre-increase the pressure of gas solution before it enters the second gas-liquid separator. This preliminary pressure increase enables the second separator to operate at higher pressure, thereby achieving high concentration gas solution without requiring the first separator to handle extreme pressures, thus resolving the contradiction between concentration and structural complexity.
2Reliability
If a single gas-liquid separator is used, then the device structure is simple, but fluctuations in delivery pressure cannot be suppressed
Solution Approach 1:
The second gas-liquid separator is strategically positioned downstream of the pressure booster pump to function as a pressure damping chamber. This separator absorbs and cushions pressure fluctuations generated by the pump before the gas solution is delivered to the use point. By providing this cushioning effect in advance, the system achieves stable delivery pressure without requiring additional complex pressure control mechanisms.
Solution Approach 2:
The system uses two gas-liquid separators in series where the second separator specifically serves as a pressure stabilization stage. This segmentation of functions (first separator for separation, second separator for pressure stabilization) enables reliable pressure delivery while maintaining a relatively simple overall structure through the natural damping effect of the second separator chamber.
3Quantity of substance
If pressure is increased in the gas-liquid separator to achieve high concentration, then gas solution concentration improves, but delivery pressure fluctuations increase
Solution Approach 1:
The system separates the pressure increase function from the pressure delivery function by using two distinct gas-liquid separators. The first separator operates at lower pressure for initial separation, while the pressure booster pump increases pressure between separators. The second separator then operates at higher pressure to achieve high concentration while simultaneously acting as a damping chamber to stabilize delivery pressure, thus resolving the contradiction between concentration and pressure stability.
Solution Approach 2:
The second gas-liquid separator acts as an intermediary element between the pressure booster pump and the delivery point. It receives high-pressure gas solution from the pump, allows pressure fluctuations to be dampened within its chamber, and then provides stabilized pressure to the use point. This intermediary role enables both high concentration (through high pressure operation) and pressure stability (through damping effect) to coexist.
