How to keep the liquid nitrogen container daily
Date: Feb 18, 2020
Placement of liquid nitrogen storage tank
Liquid nitrogen tanks should be stored in a well-ventilated and cool place, and should not be exposed to direct sunlight. Due to its precise manufacturing and inherent characteristics, no matter when it is used or stored, liquid nitrogen tanks are not allowed to tilt, lay horizontally, inverted, piled up, and hit each other. It must be handled gently and kept upright at all times.
Cleaning of liquid nitrogen storage tank
When the liquid nitrogen tank is not in use, rinse it with clean water, drain the water, dry it with a blower, and place it at room temperature for use. After the liquid nitrogen in the liquid nitrogen tank is volatilized, the remaining material (such as frozen sperm) will quickly melt, become a liquid material and attach to the inner liner, which will cause corrosion to the inner liner of the aluminum alloy. The nitrogen tank must be scrapped, so it is necessary to scrub the tank after the liquid nitrogen in the liquid nitrogen tank is depleted. The specific brushing method is as follows: first remove the inner cylinder of the liquid nitrogen tank, remove the liquid nitrogen, and leave it for 2-3 days. After the temperature in the tank rises to about 0 ° C, pour warm water at about 30 ° C, and wipe it with a cloth. If individual melting substances are found sticking to the bottom of the liner, be sure to wash them carefully. Then rinse it with water several times, and then invert the liquid nitrogen tank, put it in a safe place where it should not be overturned, and let it air dry, or use a blower as described above. Note that during the entire brushing process, the action should be light and slow. The temperature of pouring water should not exceed 40 ℃, and the total weight should not exceed 2kg.
Third, the safe transportation of liquid nitrogen tanks
The liquid nitrogen tank must be installed in a wooden frame and cushioned during transportation. Fillers should be used to separate the tanks from one another to prevent bumps and knocks. When loading and unloading the truck, it is necessary to strictly prevent the liquid nitrogen tank from hitting, and not to drag on the ground at will, so as to avoid reducing the service life of the liquid nitrogen tank.
