Intelligent self-adaptive pressure swing adsorption nitrogen making machine

Abstract

The invention discloses an intelligent self-adaptive pressure swing adsorption nitrogen making machine. The nitrogen making machine comprises a nitrogen making machine body, an air compressor, a nitrogen purification device and a nitrogen storage box. A gas inlet of the nitrogen making machine body is fixedly connected with a first connecting pipeline; the other end of the first connecting pipeline is fixedly connected with the gas outlet end of the air compressor; a connecting branch pipe is fixedly connected to the side face of the first connecting pipeline; a pressure detector is fixedly connected to the top of the connecting branch pipe; a first flow limiting control valve is arranged at the position, close to the nitrogen making machine body, of the side face of the first connecting pipeline; and the gas outlet end of the nitrogen making machine body is connected with the nitrogen purification device through a pipeline. According to the nitrogen making machine, flow limiting control valves are arranged at the two ends of the nitrogen making machine, and the pressure detector is further arranged on one side of the first flow limiting control valve, so that the gas inlet amountand the gas outlet amount of the nitrogen making machine can be well controlled, and the purity of the nitrogen making machine can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent adsorption nitrogen generators, in particular to an intelligent self-adaptive pressure swing adsorption nitrogen generator. Background technique [0002] Pressure swing adsorption nitrogen generator (referred to as PSA nitrogen generator) is a nitrogen generating equipment designed and manufactured according to pressure swing adsorption technology. Air is used as raw material, high-quality carbon molecular sieve is used as adsorbent, and the principle of pressure swing adsorption (PSA) is used to selectively adsorb air by using molecular sieves filled with micropores to achieve the purpose of oxygen and nitrogen separation. [0003] The nitrogen purity produced by the traditional PSA nitrogen generator structure is difficult to automatically adjust, and the purity of the nitrogen produced will be unstable due to the influence of the air flow rate. Contents of the invention [0004] The obje...
