Some reasons for explosion of liquid nitrogen tank

Article source:Some reasons for explosion of liquid nitrogen tank  Hits:197  Release time:2022-09-28

  Liquid nitrogen tanks are often used in precision industry, food, medicine and other industries, but in the process of use, especially in the process of filling and storing liquid nitrogen, there are more and more accidents of liquid nitrogen container explosion. What is the situation? Today we will talk about some reasons for the explosion of liquid nitrogen tank:

  1. High pressure and high temperature

  Liquid nitrogen is mainly cooled by compressed air, and it is recovered to nitrogen during gasification. After gasification, the volume of one liter of liquid nitrogen will expand 180 times when the temperature rises by 15 ℃. Therefore, if the external pressure temperature exceeds the cooling temperature and pressure that the liquid nitrogen tank can withstand, explosion will occur.

  2. Vibration

  The liquid nitrogen tank is generally designed with a special shock proof design. Whether it is used for storage or transportation, it can have a good shock proof effect. However, if it receives a strong collision and vibration, it may cause damage to the insulation layer or other components and cause explosion.

  3. Seal leakage

  If the storage environment of liquid nitrogen tank is poorly ventilated, it may lead to the continuous accumulation of nitrogen and hydrogen concentration distribution in the room, and finally reach the explosion limit and cause explosion.

  4. Other reasons

  In addition to the above three points, there may also be a material problem. Generally, liquid nitrogen tanks are made of pure aluminum and stainless steel cold-rolled steel plates. If these raw materials do not meet the standard requirements, explosion may occur.

  The above are some reasons for the explosion of liquid nitrogen tank. If you want to know more about it, you can visit Haisiyuan's official website www.hsy515.cn!
