The application range of programmable valve is introduced
The following is mainly about the application of program-controlled valve in PSA process and the role of program-controlled valve in PSA device.
Requirements of PSA process for programmable valves
PSA is a physical process of approximate isothermal change. It is a selective adsorption under certain working conditions by using the different adsorption capacity of different components on the adsorbent in the gas medium, and the adsorbent is regenerated by depressurization. In the production process, it is required to switch valves periodically, and the number of valves is large, the action is frequent, and manual operation is impossible. Due to the particularity of the PSA device process, in order to ensure the long-term stable and reliable operation of the device, the programmable valve must meet the following requirements :
1, good sealing performance, often subject to frequent periodic action and keep not leaking.
2, the valve switch speed should be fast, with different valve diameter of its opening and closing time should be less than 3 seconds.
3.It has two-way pressure resistance and high-speed airflow erosion resistance.
According to the process requirements, it is easy to realize the functions of regulating function and valve position status on-site indication and remote transmission.
The role of program-controlled valve in PSA device
The PSA unit is a highly automated device. Each adsorption tower must undergo adsorption ( A ), one-average drop ( 1L ), forward pressure relief ( PP ), two-average drop ( 2L ), reverse pressure relief ( L ), flushing ( P ), two-average rise ( 2H ), final charge ( FH ) and other processes. These process steps are completed by switching the program-controlled valve. At this time, the program-controlled valve is like the heart of the device. Frequent, stable, and sequential opening and closing ensure the smooth operation of the process and the continuous and stable output of the product.Suzhou Jiarui Gas System Co., Ltd.is a science and technology company specializing in the research and development of gas separation and purification technology.
