Welcome!
When using liquid nitrogen for a short period of time or over a short distance, insulated bottles, cups, etc. can also be used as containers. However, if the pot body has a plastic handle, it is easy for liquid nitrogen to freeze and crack, so special care should be taken when using it.
There are two main types of storage containers for liquid nitrogen tanks: low-temperature tank (mobile or fixed) and liquid nitrogen biological storage tank. Low temperature tank is a closed pressure vessel, with the tank body wrapped in a vacuum layer and a filling layer, providing insulation effect. The liquid nitrogen biological storage tank is an open insulation tank, also wrapped in a vacuum layer, but the tank mouth can be opened and there is no pressure inside the tank.
To ensure storage safety, hydrochloric acid containers are usually equipped with safety valves and level gauges. The safety valve can automatically open and release pressure when the internal pressure of the storage tank is too high, preventing the occurrence of explosion accidents. The liquid level gauge can display the real-time level of hydrochloric acid in the storage tank, making it convenient for operators to timely grasp the storage situation.
The working principle of hydrochloric acid containers is relatively simple. When storing hydrochloric acid, it is injected into the storage tank through an inlet pipeline. During storage, hydrochloric acid in the storage tank is evenly distributed through natural convection and diffusion. When hydrochloric acid is needed, it is extracted through the outlet pipeline for production use.
