The Design of 15m3 Oxygen Buffer
Abstract: The buffer tanks are widely used in the chemical industry. When the pressure of the system and fluid-sexual medium flow rate are unstable, and the amount of storage is not enough, the buffer tank will be able to play a significant role. It can play a role of buffering and ensure the production process safely and stably, when the gaseous medium transports.
The oxygen buffer means that when the media in the process of transferring, reaction and compressing, the buffer can keep the pressure of the system and flow stably, and provide the guarantees of the security and efficiency for the process of the production. The issue is put forward for that the system can be ensure safely, stably and separation. This design is mainly to do a proper buffer tank, to determine the subject material, import and export size and the diameter of the cylinder, and the structure design. The main design has a manhole, discharge opening at the bottom of DN25, safety valve etc, and doing the strength calculation. This design can solve the problem of the instability, medium flow rate and separation in the process of production in the chemical industry. It has the important meaning.
