Overall, the main function of liquid nitrogen storage containers is to ensure safe and effective storage of liquid nitrogen at low temperatures, while facilitating transportation and use. However, due to the extremely low temperature of liquid nitrogen, special attention should be paid to preventing frostbite during use.

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.

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.

In terms of material selection, hydrochloric acid containers usually use materials with strong corrosion resistance, such as stainless steel, fiberglass, etc. These materials can effectively resist the erosion of hydrochloric acid and ensure the long-term stable operation of the storage tank.

Hydrochloric acid containers are usually designed in a vertical cylindrical shape to meet the needs of large-scale storage. The tank body is welded from steel plates and has undergone special treatment inside to prevent corrosion of the material by hydrochloric acid. At the same time, the storage tank is also equipped with inlet and outlet pipelines, safety valves, liquid level gauges and other auxiliary equipment to facilitate operation and management.
