How to use a steam ejector

2021-08-27


In the steam ejector, the jet pump type temperature reducing pressure reducer uses the steam ejector as the main part of the pressure reducer, and will increase some clipping device combination, it can adjust the pressure and temperature of the steam at the same time, and the hot steam recovery of the exhaust gas is a good energy-saving equipment, it is different from the conventional alkali temperature pressure reducer we often use Conventional pressure reducer, its thermal process is often steam, effectively can reduce the energy reduction of a process, The steam ejector temperature and pressure reducing device can make the effective use of working steam rationally.
       
Steam ejector can meet the user's ideal equipment for different pressure requirements, it can increase low pressure with the help of high-pressure steam, reduce the grade of high-pressure steam at the same time, improve the grade of low-pressure steam, can produce a steam between the steam pressure between low pressure and high pressure, it can be used in thermal power plant steam turbine pumping heat supply, pressure matching has been a good application of steam ejector condensate, in the discharge process often produces a large amount of steam, If this steam is continuously emptied, it will not only waste energy, but also cause environmental pollution, and then with the help of jet pump condensate recovery device, the condensate can be well recovered, and the steam generated can be reused after improving the grade of steam.
       
Using the steam ejector as the main body of the temperature and pressure reducing device, it can provide customers with a low pressure and low temperature steam. Temperature and pressure reducer can be divided into two types, one is an integrated temperature and pressure reducer, the function of temperature reduction and pressure reduction are carried out inside the same temperature and pressure reducing valve, and the other is the split temperature and pressure reducer separates these two functions, which is more stable during operation, and the control accuracy is high, the adjustment is more sensitive, and the impact of the net difference is effectively removed.
       
The temperature and pressure reducer consists of a control system, a pressure reduction system, a steam ejector and a safety protection system. Its features are as follows: the main controller adopts high-precision multi-function digital controller, with powerful functional components, friendly man-machine interface and fast and accurate PID control loop, to achieve intelligent unattended, flexible parameter setting, and can be expanded according to user requirements. The depressurization process of steam in the steam ejector is realized by throttling of the pressure reducing valve and the orifice plate, and the number of decompression stages is determined by the difference in steam pressure after the new steam is depressurized. The pressure adjustment of the pressure reducing valve is completed by the electric actuator of the large actuator, which runs smoothly and has a long life, and can maintain the stability of the secondary steam pressure no matter how the primary steam pressure fluctuates according to the requirements of the secondary steam setpoint.
