liquid nitrogen tank What are the human factors of the explosion? Self pressurized liquid nitrogen tank

Liquid nitrogen tank is a kind of dangerous chemical. If it is not used properly, it will easily explode. In light, it will cause equipment damage, or even lead to heavy casualties. Therefore, the safety of liquid nitrogen container in the use process should be highly valued. There are many reasons leading to the explosion accident of liquid nitrogen container. What we should say here is human factors. Nanjing liquid nitrogen tank experts remind you to avoid using liquid nitrogen tank in time.

(1) improper storage and transportation

The storage types of liquid nitrogen tank can be generally divided into storage tank and transport tank. The storage tank is mainly used for the static storage of indoor liquid nitrogen, and it is not suitable for remote transportation under working condition.

(2) improper use

If the long-term use of liquid nitrogen tank, if the regular maintenance and inspection and maintenance are not done in the operation process, the equipment will have unsafe hidden danger, which may cause explosion accident.

When operating the liquid nitrogen tank, if the exhaust valve is not opened or the opening degree is not enough, the pressure of the inner cylinder will increase after long time of natural evaporation of liquid nitrogen. At this time, if there is no safety protection device, the pressure continues to rise, which may lead to the cracking of the original defects of the nozzle at the bottom of the booster pipe. Once the liquid nitrogen seeps into the interlayer space and vaporizes, the pressure of the interlayer increases rapidly, which will lead to the explosion of the outer cylinder.

Some liquid nitrogen tank operators without safety education, only rely on the master's oral teaching of operating skills before taking up their posts. The safety quality and skills are poor, and accidents are easy to occur.   

(3) leakage of liquid nitrogen

The liquid nitrogen in the tank can not be discharged normally for a long time, or a large amount of leakage into the interlayer space for gasification may also lead to the explosion of liquid nitrogen container. Self pressurized liquid nitrogen tank
