Background

The pressure swing adsorption nitrogen making machine is a simple nitrogen making device, takes air as raw material, consumes only electric energy consumed by an air compressor, and has the advantages of low operation cost, low energy consumption, high efficiency and the like. The adsorption tower has wide application in the industries of chemical industry, metallurgy, pharmacy, food, electronics and the like, in smaller pressure swing adsorption nitrogen making equipment, because the proportion of the volume of the adsorption tower relative to an air inlet is not very different, raw material air can be uniformly adsorbed by the molecular sieve through the air inlet directly, so that an air flow distributor is not needed, the molecular sieve can be used more efficiently, but when the nitrogen making equipment with large gas production is designed, the volume of the adsorption tower is correspondingly increased, at the moment, if no proper air flow distributor is arranged in the adsorption tower, the raw material air is uniformly distributed to all corners of the adsorption tower, the molecular sieve in the tower cannot be efficiently utilized, and a part of the molecular sieve does not participate in the nitrogen making work.

The current gas distributor aperture is mostly the circular sheet structure that the size equals, under the effect of pressure, because the inlet port is in the bottom central point of adsorption tower and puts, gaseous when passing through the gas distributor module, gas distributor intermediate position gas flow is great, lead to when passing through the molecular sieve, gaseous also can concentrate on the intermediate position, molecular sieve on every side can not obtain make full use of, thereby lead to equipment nitrogen making inefficiency, if will reach the same nitrogen gas output of same purity, just must load more molecular sieves, the cost rises, simultaneously because load more molecular sieves and need more bulky, also increase more energy consumptions during the use, can't satisfy the user demand yet.
