Solution Overview
Problem
Existing liquid power generation devices that utilize repeating transient confined liquid pressures, such as ram pumps, are inefficient and wasteful, typically pumping only 10 to 25 percent of the input water while releasing the remaining 75 to 90 percent as waste, limiting their practical applications.
Innovation Solution
A transient liquid pressure power generation system that includes a liquid source and a transient pressure drive device capable of generating high pressure transient waves, utilizing a heat source to recycle and reuse the liquid, thereby improving efficiency and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If ram pumps are used to pump water using transient pressure waves, then power generation is achieved, but 75 to 90 percent of the water is wasted
Solution Approach 1:
The patent applies the discarding and recovering principle by capturing the transient pressure wave that would otherwise be wasted and redirecting it to drive a power generation device. The system recovers energy from the pressure wave reflection off the closed valve, converting what would be discarded energy into useful mechanical work to generate electricity.
Solution Approach 2:
The patent converts the harmful water hammer effect (sudden pressure surge) into a beneficial force for power generation. By closing the valve rapidly to create the pressure wave and then using that same wave to drive the turbine, the system transforms a potentially damaging phenomenon into a useful energy source.
2Power
If ram pumps operate with limited circumstances and high waste flow, then transient pressure waves can be utilized, but efficiency is poor
Solution Approach 1:
The patent replaces the traditional mechanical pumping mechanism of ram pumps with a power generation system. Instead of using the transient pressure wave to mechanically pump water, the system uses the wave to drive a turbine connected to a generator, substituting mechanical work with electrical energy generation.
Solution Approach 2:
The system utilizes periodic transient pressure waves generated by rhythmic valve closure to continuously drive the turbine. The periodic opening and closing of the valve creates repeating pressure surges that rotate the turbine blades, converting intermittent hydraulic impulses into continuous rotational motion and electrical power.
