Is it necessary to install a nitrogen inlet pipe for the nitrogen-sealed storage tank? Can it be blown directly at Class A liquids?

A nitrogen inlet pipe is required for the nitrogen-sealed storage tank. The installation of nitrogen inlet pipes is not merely about introducing nitrogen into the storage tank; various factors such as the distribution of nitrogen, mixing, and safety also need to be taken into account. Typically, the outlet of the nitrogen inlet pipe needs to be designed in a dispersed shape, so that nitrogen can be distributed more evenly within the tank, reducing the oxygen concentration and thus protecting the stored materials. However, nitrogen cannot be blown directly at Class A liquids either. This is mainly because Class A liquids are often flammable and explosive, and directly blowing nitrogen can generate static electricity, leading to fires or explosions. Therefore, the outlet of the nitrogen inlet pipe often needs to be located at the top or side wall of the tank, equipped with appropriate diffusion devices to reduce velocity and prevent the generation of static electricity. At the same time, regular inspection and maintenance of the nitrogen inlet pipe are also required to ensure its proper operation. Of course, the specific methods of operation need to be based on the particular engineering design and relevant safety regulations. .

Ours is connected directly to the top of the tank, with the liquid level in the pipe reaching at most 80%. Generally, it cannot reach the liquid

Without an intake pipe, how can nitrogen be introduced?

As the nitrogen gas enters the storage tank and expands, its velocity drops to almost 0, so there is no liquid being blown along
