A pressure pipeline renovation and upgrade system that utilizes high-pressure air injection from an air compressor to mix with water flow to improve the power generation efficiency of a hydropower station.

This invention provides a pressure pipeline upgrade system that improves the power generation efficiency of hydropower stations by using a high-pressure air compressor to inject air and mix it with water. The system includes a pressure tank, an air compressor, a high-pressure connecting air pipe, a one-way check valve, a pressure equalization chamber, a pressure pipeline, a vortex guide pipe, a high-pressure jet nozzle, and a hydro-generator. The core components of this invention are: the pressure equalization chamber, the pressure pipeline, the vortex guide pipe, and the high-pressure jet nozzle. The vortex pipe and the pressure pipeline are an integral design; the vortex pipe is attached to the inner wall of the pressure pipeline, guiding the water flow in a vortex shape to accelerate and impact the hydro-generator. The vortex pipe is designed as a hollow structure with evenly distributed spiral air holes. The high-pressure air output from the air compressor is injected into the water flow spirally through these air holes along the path of the vortex pipe, thoroughly mixing with the water. Simultaneously, influenced by the water level difference in the upstream pressure pool, the water flow naturally forms a strong vortex effect, further enhancing the rotational power of the water flow. This achieves a dual pressurization effect from the high-pressure mixture of water and air, causing the water pressure and velocity to increase several times before impacting the turbine generator blades and driving them to generate electricity, thereby improving the power generation efficiency of the hydropower station. This invention has advantages such as simple structure, convenient installation, easy maintenance, water conservation, and environmental friendliness, and can also bring good social and economic benefits.
