The above article is a basic overview of steam ejector introduced by the editor. If you don't know anything before, you can read it. Well, let's talk about today's knowledge first. I hope it can help relevant people.
When seeing this steam ejector, some friends are familiar with it, while others will ask what it is and where it is used. What is the function of steam ejector? These problems are also common online. Today, let's take this opportunity to give you a brief introduction. I hope it can help you.
Steam ejector is also a product with a wide range of applications. In fact, it is also quite common in life, but many people do not know its name. The first thing you need to know here is that the steam ejector is a vacuum device, which is the application of jet technology in the field of heat transfer. This technology was introduced into China in the 1980s and has been applied in engineering in recent years. The steam jet pump has simple structure, small investment and reliable operation. This can naturally and reasonably match the steam pressure level, recover low-grade steam and improve steam utilization efficiency. This is an important way to save energy. It is widely used in food, pharmaceutical, chemical, metallurgical and other industries. In fact, this product is mainly composed of nozzle, receiving chamber, mixing chamber, diffuser chamber and other parts. The working principle of its steam ejector is that high pressure steam will produce high speed airflow when passing through the nozzle. When used, a low pressure area can be generated at the nozzle outlet. In this area, low-pressure steam is sucked in, high-pressure steam compresses low-pressure steam while expanding, and the grade of low-pressure steam increases with the edge pressure of high-pressure steam. Then it can be fully mixed through the mixing chamber, and the mixed steam can recover part of the pressure through the diffuser. After reaching the required steam pressure, it can be supplied to the heat user.
In addition, when using steam ejector, different structural designs can be carried out according to the parameters of high and low pressure steam to obtain steam of different pressure levels to meet the requirements of different heat users. The low-pressure steam inhaled can be either scattered waste steam or flash steam generated by condensate, which can make full use of low-enthalpy heat energy and achieve the purpose of energy conservation. The energy saving rate of steam ejector can reach about 35%, which has good practicability. The steam ejector is powered by the energy difference before and after the pressure reduction of the advanced working steam. The ratio of the heat provided to the heat user through the jet pump cycle to the heat consumed by the working steam is called the heating coefficient, which is also mainly expressed in cop here. The greater the cop, the higher the efficiency of the jet pump. Of course, there are also some important points. For example, the steam ejector is different from the traditional temperature and pressure reducer. The thermal process of the conventional pressure reducer is the process of reducing the effective energy of the live steam and devaluing the energy. The jet pump type temperature and pressure reducer can reasonably use the effective energy of the working steam. But when buying, we also need to look for regular manufacturers. In this way, we can meet these basic advantages only if we are guaranteed in all aspects.
