Description

Technical Field

[0001] The invention relates to the technical field of jet acceleration equipment, and in particular to a gas-liquid two-phase jet acceleration device. Background Art

[0002] Jet processing is a special processing technology. Its equipment uses the principle of liquid pressurization to convert the mechanical energy of the power source into pressure energy through a specific device. Water with huge pressure energy passes through a small hole nozzle, and then converts the pressure energy into kinetic energy to form a high-speed jet, thereby achieving full mixing of the gas and liquid phases. In order to speed up the mixing speed, a gas-liquid two-phase jet acceleration device is required. Although the common gas-liquid two-phase jet device can mix gas and liquid during use, the conventional acceleration device has a low mixing rate and a fixed structure, resulting in limited outlet pressure, which cannot meet the requirements of some high-pressure scenarios. At the same time, if the mixed medium contains viscosity, long-term use will cause the outlet pressure to decrease, the jet to become smaller, and it cannot meet the use requirements. For example, the application number is: 2023116215430, and the name is: A technical solution of a new annular propeller structure based on gas-liquid two-phase flow. This technical solution can adjust the power of the liquid or air intake to keep the gas-liquid two-phase in a high-efficiency state. However, since the volume of the gas-liquid mixing chamber is consistent and the structure is fixed, its outlet pressure is limited, and the propulsion efficiency cannot be increased indefinitely.
