A device that uses physical methods to separate oxygen in the air to obtain nitrogen is called a nitrogen generator. Nitrogen generators are mainly divided into three types, namely cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation. Law. Today, the nitrogen generator manufacturer-Suzhou Hengda Purification Equipment Co., Ltd. will tell you how to fill and use the deoxidizer of the nitrogen generator.

1. Filling

1. Before filling, the nitrogen generator manufacturer said that the reactor must be cleaned and the air tightness test of the reactor must be carried out. If the packing height is more than 1 meter, it is recommended to pack the catalyst into a bottomless cloth bag before feeding it into the reactor.

2. Before installing the flange, clean air must be used to purge from the bottom of the reactor to blow out the powder produced by impact and friction during the filling process.

3. Close the flange and conduct an air tightness test on the entire reactor.

2. Feeding

For hydrodeoxygenation in hydrogen or nitrogen: The catalyst does not need to be activated and can be directly put into use. Before use, the air in the reactor must be replaced with nitrogen by means of charging and discharging pressure. Nitrogen generator manufacturers can directly introduce pre-refined hydrogen or hydrogenated nitrogen when feeding, and the catalyst in the reactor can perform catalytic reaction to remove trace oxygen in the gas.

3. Replacement; when it is determined by analysis that the catalyst has reached its lifespan, it must be replaced. When replacing, the material in the bed should be replaced by the method of nitrogen charging and discharging (0.5-0.7MPa) first, and then a certain amount of air (10-100%) should be added to the nitrogen to purge the bed. And gradually increase the amount of added air, until the added gas is all air, the catalyst can be removed and replaced.

  Precautions:

1. It is strictly forbidden to enter a large amount of oxygen (≥3%) during use.

2. Strictly do the air tightness test of the system.

3. Before replacing the deoxidizer or opening the deoxidizer, the nitrogen generator manufacturer must completely replace the hydrogen in the system. When the device is shut down for some reason, the deoxidizer cannot be in direct contact with the air. It is necessary to use nitrogen to purge the hydrogen in the bed before it can be discharged or contacted with air, otherwise the catalyst may be easily pulverized.
