Embodiment 1
[0032] A nitrogen production system such as figure 1 and figure 2 As shown, it includes the base 1 and the air compressor 2, air buffer tank 3, air treatment device 4, nitrogen generator 5, nitrogen buffer tank 6, pressurized delivery, which are fixedly installed on the base 1 and connected sequentially through pipelines according to the airflow direction. Device 7 and high-pressure nitrogen storage tank 8.
[0033] Wherein, the base 1 is a rectangular frame structure formed by welding or boltingmetal profiles (such as channel steel or H-shaped steel). The air compressor 2 is a piston type or a screw type compressor, and is preferably an oil-free air compressor. The air compressor 2 usually has an independent chassis, and the chassis is fixed on the base 1 by bolts.
[0034] The air buffer tank 3 is connected with the air outlet of the air compressor 2 through a pipeline, so as to buffer and temporarily store the compressed air produced by the air compressor 2 . The air b...
Embodiment 2
[0041] A nitrogen production method, such as image 3 shown, including the following steps:
[0042] Step S1, compress the air with an air compressor, and send the compressed air into the air buffer tank;
[0043] Step S2, sending the compressed air in the air buffer tank to the air treatment device, and performing one or more treatments of oil removal, drying, cooling, and purification on the compressed air sent in through the air treatment device;
[0044] In this step, the compressed air in the air buffer tank flows to the air treatment device through its own pressure, and in this embodiment, the air treatment device preferably includes an oil removal tank, a cold dryer, a purifier and The buffer tank is used to degrease, dry, cool and purify the compressed air, and then buffer the air.
[0045] Step S3, sending the treated compressed air into a nitrogen generator, and separating the air into oxygen and nitrogen through the nitrogen generator;
[0046] In this step, the ...

Abstract
The invention discloses a nitrogen making system and a nitrogen making method, and belongs to the technical field of nitrogen making, wherein the nitrogen making system comprises a base, and an air compressor, an air buffer tank, an air processing device, a nitrogen making machine, a nitrogen buffer tank, a pressurizing conveying device and a high-pressure nitrogen storage tank which are fixedly mounted on the base and are sequentially connected through pipelines according to the airflow direction; and the nitrogen making method comprises the step of preparing nitrogen according to the nitrogen making system. The system is high in integration level, all the subsystems are mounted in a centralized mode, and thus flexible deployment is facilitated, the occupied area is small, and in addition, damage caused by unstable pressure air impacting equipment can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of nitrogen production, in particular to a nitrogen production system and a nitrogen production method. Background technique [0002] A nitrogen generator is a device that uses air as a raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. The nitrogen generator is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. The nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as the adsorbent, and adopts the principle of pressure swing adsorption (PSA) at room temperature to separate air to produce high-purity nitrogen. nitrogen. Usually two adsorption towers are connected in parallel, and the imported PLC controls the automatic operation of the imported pneumatic valve to alternately perform pressurized adsorption and decompressed regeneration to complete the separation of nitrogen and oxyg...
