Foshan nitrogen machine manufacturer talk about how the nitrogen machine is made of nitrogen? Compressed air passes through the semi-permeable membrane, oxygen can pass through smoothly, and the high concentration of nitrogen is not passed.

Home oxygen generators take advantage of this process, but instead of using oxygen, they release nitrogen into the air. If you collect the released gas, you get a high concentration of nitrogen.

Raw air through air compression, purification, into the precision filter, through the spiral, condensation, surface filtration to remove most of the liquid water and oil, and then into the freezer dryer, the refrigerant compressor refrigeration system will be compressed air pressure dew point down to 2 ~ 3℃, remove a lot of water, and then into the super-fine filter, Further remove the solid particles contained in the compressed air, so that the compressed air quality reaches 0.01μm, and then enter an activated carbon tank, remove most of the oil, hydrocarbons, etc., through the air buffer tank into two pressure swing adsorption separation system filled with adsorbent, that is, NGN-110D type nitrogen production unit. Clean compressed air enters from the bottom of the adsorption tower, and after the air is diffused by the air diffuser, it evenly enters the adsorption tower for oxygen and nitrogen adsorption separation, and then flows out of the outlet nitrogen into the nitrogen buffer tank, the nitrogen production process is about 1 minute, and then the pressure is equalizing and reducing (to normal pressure), removing the adsorbed impurity components (mainly oxygen), and completing the regeneration of the adsorbent. The two adsorption towers are operated alternately, and the raw material air is continuously fed, and the purity of continuous production is ≥99.9%; Output ≥110Nm3/h; Pressure 0.6MPa (adjustable); Nitrogen with dew point ≤-40 ° C.

After the nitrogen from the nitrogen machine is heated to a certain temperature by the heat exchanger and heater, it enters the deoxidizer filled with carbon catalyst, the residual oxygen in carbon and nitrogen reacts to produce carbon dioxide and trace water, and then enters the high-efficiency cooler to normal temperature, and then removes carbon dioxide and water through the suction machine filled with molecular sieve, and finally passes through the high-purity nitrogen buffer tank. Precision filter to obtain high purity nitrogen, nitrogen purity ≥99.999%; The output is ≥100Nm3/h; Outlet temperature ≤40℃, pressure 0.5MPa (adjustable) nitrogen atmospheric pressure dew point -70℃.
