[0025] It should be noted that the utility model is a nitrogen purification device. When in use, general nitrogen is first guided to the deoxygenation component 2 to remove oxygen in the general nitrogen. After removal, it is condensed by the cooler 3. After condensation, the gas is cold-dried by the cold dryer 4. The cold-dried gas is dried and adsorbed by the drying adsorption component 5. After drying and adsorption, the nitrogen is precisely filtered, pre-stored and detected by the self-checking filtering and nitrogen exhausting component 6. In the process of purifying nitrogen, multi-angle leakage detection is performed on it through the multi-angle leakage detection support component 1. The multi-angle leakage detection support component 1 includes an installation support base 101, a bottom nitrogen detector 102, and a bottom leakage sound and light detector 103. The early warning device 103, the support column 104, the limit sliding top plate 105, the sliding nitrogen detector 106 and the sliding sound and light early warning device 107 are installed. Before use, the bottom nitrogen detector 102 installed on the support base 101 and the sliding nitrogen detector 106 on the limit sliding top plate 105 are adjusted and fixed according to the pipeline position of the nitrogen purification device. After fixation, the bottom leakage sound and light early warning device 103 and the sliding sound and light early warning device 107 are connected to the bottom nitrogen detector 102 and the sliding nitrogen detector 106 respectively. After connection, the limit sliding top plate 105 is installed in alignment with the support column 104 installed on the support base 101. When in use, the bottom nitrogen detector 102 and the sliding nitrogen detector The detector 106 performs leakage detection on the connection of the nitrogen purification device. When the bottom nitrogen detector 102 or the sliding nitrogen detector 106 detects nitrogen leakage, the bottom leakage sound and light warning device 103 and the sliding sound and light warning device 107 are used for sound and light warning respectively. When in use, multi-point leakage detection can be performed on the connection of the purification device, and nitrogen overflow can be discovered in time and the leakage position can be located and warned to avoid hypoxia in the working environment and equipment damage. The self-checking filtering and nitrogen exhausting component 6 includes a precision filtering tank 601, a filtering inlet pipe 602, a filtering exhaust pipe 603, an air intake control valve 604, a No. 1 nitrogen purity detection storage tank 605, and a No. 2 nitrogen purity detection storage tank 60 6. The top reflux valve 607, the reflux pipe 608 and the two-way valve drain pipe 609, when in use, first transfer the dried and adsorbed nitrogen to the precision filter tank 601 through the filter inlet pipe 602, and then filter it through the precision filter tank 601. After filtering, the filtered nitrogen is transferred to the No. 1 nitrogen purity detection storage tank 605 through the air intake control valve 604 of the filter drain pipe 603, until the No. 1 nitrogen purity detection storage tank 605 is full, the inlet of the No. 1 nitrogen purity detection storage tank 605 is closed through the air intake control valve 604, and after closing, the filtered nitrogen is continuously transferred to the No. 2 nitrogen purity detection storage tank 606. During the transfer, the No. 1 nitrogen purity detection storage tank 605 performs purity detection on the internal nitrogen.When the purity reaches the standard, it is discharged and stored through the two-way valve pipe 609. When it is detected that the purity does not reach the standard, it is transferred to the reflux pipe 608 through the top reflux valve 607 for reflux secondary filtration. The No. 1 nitrogen purity detection storage tank 605 and the No. 2 nitrogen purity detection storage tank 606 perform relay storage detection through the filter pipe 603 and the air intake control valve 604. When in use, the nitrogen can be pre-stored for purity detection, and the gas that does not reach the standard can be refluxed for secondary purification to ensure the quality of nitrogen purification.
