Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generator filtering, in particular to a nitrogen generator with a dust filtering function. Background Art

[0002] The nitrogen generator is mainly composed of a compressor, a separator and a gas storage tank. The working principle of the nitrogen generator is to use air separation technology, usually using the method of compressed air, to separate oxygen, moisture and other impurities in the air to obtain high-purity nitrogen. Common nitrogen production methods include pressure friction adsorption (PSA) and membrane separation. The air enters the separator after being pressurized by the compressor. The separator is equipped with a special adsorbent. Under a certain pressure, nitrogen will be adsorbed by the adsorbent, while oxygen and other impurities are discharged through the separator. When the adsorbent reaches saturation, it is released by decompression, and the adsorbent desorbs again, and the nitrogen is further purified. This cycle can be repeated continuously to obtain nitrogen of the required purity;

[0003] During the operation of the nitrogen generator, oxygen, moisture and other impurities in the air need to be separated. Dust is inevitable during the separation process. Most of the nitrogen generators on the market do not have the function of dust filtration. For this reason, we propose a nitrogen generator with dust filtration function to solve the above problem.
