Liquid nitrogen storage tanks are generally divided into storage tanks and transport tanks. The storage tank is mainly used for indoor static storage of liquid nitrogen; The transport tank meets the transport conditions and is specially designed for shock prevention. It can not only be used for static storage, but also be transported in the state of filling with liquid nitrogen, and it can also avoid violent collision and vibration.

Use of liquid nitrogen tank

1, check before use

Liquid nitrogen tank is a special tool for liquid nitrogen, and other liquids are not allowed. Before filling the liquid nitrogen tank with liquid nitrogen, it is necessary to check whether the shell is sunken and whether the vacuum exhaust port is intact.

If it is damaged, the vacuum degree will be reduced, and in severe cases, air will be introduced, which makes it impossible to maintain thermal insulation. At this time, the upper part of the tank will frost, and the loss of liquid nitrogen will increase, losing the value of continuous use. Secondly, check whether the inside of the water tank is clean and dry. If there are foreign objects, be sure to take them out to prevent the liner from being corroded.

2. Filling with liquid nitrogen

When the container is filled with liquid nitrogen for the first time and then after long-term use, the filling speed should not be too fast because the container is at room temperature. A small amount should be injected first to gradually cool the container, and then the filling speed should be accelerated after the boiling phenomenon of liquid nitrogen is weakened. Otherwise, liquid nitrogen will boil and splash outward, causing frostbite. Liquid nitrogen should not be too full, and the liquid level should not be high enough to contact the glass fiber reinforced plastic neck pipe.

Do not flush liquid nitrogen on the neck tube. Insert the filling pipe head into the bottom of the container and inject liquid nitrogen. When filling with a funnel, there should be a gap between the funnel and the neck so that nitrogen can be discharged freely.
