Precautions for the use of cryogenic liquid nitrogen tanks

Cryogenic storage tanks In the industry, cryogenic storage tanks are often used to store and transport liquid nitrogen, and are also based on the characteristics of liquid nitrogen. Therefore, there are some items that need to be paid attention to when using storage tanks to ensure the effectiveness and safety of storage. In the case of using cryogenic storage tanks to store liquid nitrogen, ensure that the storage tank is cleaned every year to prevent the liquid nitrogen from corroding the tank wall. Before cleaning the storage tank, discharge the remaining liquid nitrogen. The discharge needs to follow the standard method To perform the operation, use a neutral lotion for cleaning, and then use a large amount of water for a second rinse.
 
The cryogenic storage tank cannot be put into use immediately after cleaning to ensure the requirements of the cryogenic storage tank. Therefore, the temperature of the cleaning liquid cannot exceed 40 degrees. Too high temperature will affect the performance of the storage tank.
 
Cryogenic storage tanks are equipment for high-vacuum storage of cryogenic liquids. During use, attention should be paid to the relevant maintenance methods to ensure that the storage role of the storage tank is fully utilized, and at the same time, the service life of the equipment can be prolonged to reduce the frequency and frequency of equipment replacement. cost. Before using the cryogenic storage tank to store a large amount of liquid nitrogen, it is necessary to inject an appropriate amount of liquid nitrogen to pre-cool the tank body, and then start to fill a large amount of liquid nitrogen when the temperature in the tank is determined to be at an adapted temperature. The environment where the liquid nitrogen tank is located should be kept dry and well ventilated. In the process of storing liquid nitrogen, it is necessary to reduce the number of times of opening the lid as much as possible. At the same time, pay more attention to whether the neck plug is frozen or not, if it is necessary to remove it in time, and if there is water droplets or When it is hoarfrost, check the insulation of the tank in time to determine whether the tank is suitable for continuing to store liquid nitrogen, and do a good job of marking the cryogenic storage tank for storing liquid nitrogen, so as to facilitate detailed storage Happening.
 
When transporting cryogenic storage tanks, keep the tank upright and avoid severe vibration or impact during transportation to ensure the safety and normal performance of the tank.
