Description

Technical Field

[0001] The utility model relates to the technical field of liquid ammonia tanks, in particular to a liquid ammonia tank fixing device. Background Art

[0002] Liquid ammonia is a colorless liquid with a strong pungent odor. Ammonia is an important chemical raw material. For the convenience of transportation and storage, gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. Ammonia is easily soluble in water, and forms an alkaline solution of ammonium hydroxide after dissolving in water. Liquid ammonia is mostly stored in pressure-resistant steel cylinders or steel tanks, and cannot coexist with substances such as acetaldehyde, acrolein, and boron. Liquid ammonia is widely used in industry, is corrosive and easily volatile, so its chemical accident rate is very high. Liquid ammonia tanks need to be stored in liquid ammonia tanks during storage and transportation.
