The method is widely applied to the industries of food, pharmacy, chemical industry, metallurgy and the like.
The jet pump is used for sucking and delivering liquid by utilizing the principle that static pressure energy and dynamic pressure energy are converted when fluid flows, and can be used for sucking and delivering gas and liquid. In chemical production, the purpose of generating vacuum is often used. The jet pump mainly comprises a nozzle, a receiving chamber, a mixing chamber, a pressure expansion chamber and the like, and has the characteristics of simplicity, reliability, continuous work, no rotating part, long service life and the like. The working fluid of the jet pump can be steam or liquid. The common steam jet pump is a single-stage steam jet pump, and the working principle is that dynamic steam generates high-speed airflow when passing through a nozzle, the static pressure energy of the steam is converted into kinetic energy, a low-pressure area is generated at the outlet of the nozzle, the gas is sucked in the area, the dynamic steam compresses the pumped gas while expanding, the gas is well mixed through a mixing chamber, and after the mixed gas enters a diffusion pipe, the speed is reduced, the pressure is increased, and finally the mixed gas is discharged through a discharge port.
However, the conventional steam jet pump is slow in starting, and the amount of high-pressure steam input at the beginning of starting is not large, so that the high-pressure steam is not completely mixed with the sucked low-pressure steam, the pressure of the low-pressure steam is slowly increased, and the working efficiency of the low-pressure steam is affected.
