After reading the above contents, you must have a clear understanding of the structure and working principle of the steam ejector, and have a basic understanding of its application methods. I hope this article can help you understand this equipment.
With the rapid development of science and technology, steam ejector appears in people's vision. Steam ejector is a vacuum equipment, an application of jet technology in the field of heat transfer, and gradually applied in engineering in recent years. This steam ejector has simple structure, reliable operation and low investment cost. It can reasonably match the pressure grade of steam, recover some low-grade steam, and improve the utilization efficiency of steam knife. It is an important way to save energy at present. The steam ejector is widely used in many industries, such as chemical industry, manufacturing, food and so on.
The steam ejector is mainly composed of several parts, such as the mixed-type receiving nozzle and the diffuser. The steam ejector prompts that a relatively fast air flow will be generated through high-pressure steam with the help of water spray, and then a low-pressure area will appear at the nozzle outlet. In this area, some steam with low pressure will be sucked in. High-pressure steam, while expanding, will also compress these low-pressure steam, and then use the pressure of high-pressure steam to improve the grade of low-pressure steam, and then enter the mixing chamber to mix the mixed steam, and then restore the original pressure through the expansion type to reach the required steam pressure, which can be provided to users for use.
According to the different parameters of pressure, it can enter into different structural designs to obtain steam of different pressure levels to meet different users. Generally, the low-pressure steam inhaled can be either the discharged waste steam or some steam generated by the condensate, so that this part of steam can be reasonably used to achieve the goal of energy conservation.
The jet pump type desuperheater and pressure reducer is composed of steam ejector as the main body of the pressure reducer and desuperheater. It is a high-speed energy-saving equipment that can simultaneously regulate steam pressure and temperature and recover waste heat steam. It is different from the conventional temperature and pressure reducer. The thermal process of the conventional pressure reducer is the process of reducing the effective energy of fresh steam and energy depreciation. The jet pump type temperature and pressure reducer can make reasonable use of the effective energy of the working steam.
The steam pressure matching device is an ideal device to meet the requirements of users for different steam pressures. It uses high-pressure steam to inject low-pressure steam, reduce the grade of high-pressure steam and improve the grade of low-pressure steam, and generate steam at various pressures between high and low-pressure steam pressures.
After reading the above contents, you must have a clear understanding of the structure and working principle of the steam ejector, and have a basic understanding of its application methods. I hope this article can help you understand this equipment.
