Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a nitrogen generator structure capable of reducing noise. Background Art

[0002] The nitrogen generator is a nitrogen production equipment designed and manufactured according to the pressure swing adsorption technology. The nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as adsorbent and adopts the pressure swing adsorption principle (PSA) at room temperature to separate air and produce high-purity nitrogen. Usually two adsorption towers are connected in parallel, and the imported pneumatic valve is automatically operated by the imported PLC to alternately perform pressurized adsorption and decompression regeneration to complete the separation of nitrogen and oxygen and obtain the required high-purity nitrogen.

[0003] According to a new integrated nitrogen generator disclosed in Chinese patent CN202020597699.5, the application can absorb the noise generated by the nitrogen generator through the setting of the overall structure, thereby reducing the noise generated by the nitrogen generator to people working nearby. The existing nitrogen generator reduces noise by setting a sound insulation board inside the chassis. However, the sound insulation board can only reduce the noise of the internal nitrogen making mechanism. When the nitrogen generator is running, the entire chassis will vibrate due to the operation of the internal nitrogen making mechanism, and noise will also be generated outside when the chassis vibrates.
