Steam ejector is a vacuum acquisition device, which is the application of jet technology in the field of heat conduction. In the 1980s, this technology was introduced to China and has been applied in engineering in recent years. The steam pump has simple structure, low investment, reliable operation, reasonable matching of steam pressure grade, recovery of low-level steam and liquid, and improvement of steam and liquid utilization efficiency are important ways to save energy. This product is widely used in food, medicine, chemical, metallurgy and other industries.

Structure and working principle of steam ejector:
The steam ejector is mainly composed of nozzle, contact chamber, mixing chamber, diffuser and other parts, and the specific structure is shown in the figure. Its working principle is that high pressure steam generates high speed air flow when passing through the nozzle, and forms a low pressure zone at the nozzle outlet, where low pressure steam is inhaled. High pressure steam compresses low pressure steam during expansion, and uses the residual pressure of high pressure steam to improve the level of low pressure steam, and then fully mixes through the mixing chamber. The mixed steam recovers part of the pressure through the expansion chamber to reach the required steam pressure and supply it to the heat user. According to the high and low steam parameters, different structural designs can be carried out to obtain steam of different pressure levels to meet the needs of different heat users. The extracted low-pressure steam can be either the discharged waste steam or the flash steam generated by the condensate, which can make full use of the low enthalpy heat energy to achieve the purpose of energy conservation. The energy saving rate of steam ejector can reach about 35%, which has good practical value.
The above is the function and working principle of the steam ejector introduced to you. I hope it can help you!
