Technical Field

[0001] The utility model relates to the technical field of nitrogen drying, in particular to a nitrogen drying device for a clean nitrogen system. Background Art

[0002] Nitrogen is colorless and odorless at room temperature. If placed in a high temperature and high pressure environment, it can be mixed with hydrogen to produce ammonia. In the atmosphere, the nitrogen content is as high as 78%, and the usable amount is extremely high. Therefore, in factory production, liquid air distillation is often chosen to produce nitrogen.

[0003] Because nitrogen is an inert gas, its chemical properties are very stable. After filling the inside of the container, it can have the functions of fire prevention, explosion prevention, flame retardant isolation, and even delay the period of food spoilage. In order to ensure the quality of nitrogen, it needs to go through a series of cleaning operations before use, such as filtering and drying. The air inlet and outlet pipes of general drying machinery are often welded and locked. If the equipment connected on both sides is changed, the connection between the air pipes is also quite unstable, and it is difficult to quickly adjust and change the position.

[0004] Now, a novel nitrogen drying device for a clean nitrogen system is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a nitrogen drying device for a clean nitrogen system to solve the problem of fixing the positions of inlet and outlet pipes in the above-mentioned background technology.
