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.

Hydrochloric acid containers are widely used in various industrial fields such as chemical, pharmaceutical, and metallurgical industries. In the chemical industry, hydrochloric acid containers are used to store hydrochloric acid raw materials required in the production process; In the pharmaceutical industry, hydrochloric acid containers are used to store hydrochloric acid reagents required during the pharmaceutical process; In the field of metallurgy, hydrochloric acid containers are used to store the hydrochloric acid solution required during the pickling process. The commonality of these application areas is that they all require a large amount of storage of hydrochloric acid and ensure the safety and efficiency of the storage process.

The installation of hydrochloric acid containers should strictly follow relevant standards and specifications. Before installation, it is necessary to conduct a comprehensive inspection of the storage tank to ensure that it is intact and undamaged. During the installation process, attention should be paid to the support and fixation of the storage tank to prevent displacement or tilting during use. After installation, it is necessary to conduct pressure testing and leak detection on the storage tank to ensure its safety and reliability.

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.
