Abstract

The invention is applicable to the field of molecular sieve oxygen production and provides a device for testing comprehensive performance of an airborne multi-bed molecular sieve. The device comprisesa molecular sieve inlet air conditioning subsystem, a variable multi-bed molecular sieve subsystem, a vacuum cabin subsystem and a test subsystem, wherein the molecular sieve inlet air conditioning subsystem is connected with the variable multi-bed molecular sieve subsystem and is used for providing the inlet air meeting test requirements, the variable multi-bed molecular sieve subsystem is connected with the vacuum cabin subsystem and the test adjustment subsystem, and is used for controlling absorption and desorption of each molecular sieve bed according to the test requirements, obtainingoxygen-enriched gas by absorbing nitrogen in the air at an inlet, transmitting the oxygen-enriched gas to the test subsystem, and desorbing and transmitting the absorbed nitrogen to the vacuum cabin subsystem, the vacuum cabin subsystem is used for collecting the nitrogen, and the test subsystem is used for obtaining performance parameters representing the performance of the molecular sieve according to the oxygen-enriched gas. The device is advantaged in that performance of molecular sieve oxygen production equipment can be tested, and development and research of related products are facilitated.

Description

technical field [0001] The invention relates to the technical field of molecular sieve oxygen production, in particular to a test device for comprehensive performance of airborne multi-bed molecular sieves. Background technique [0002] The molecular sieve oxygen concentrator is the core component of the airborne molecular sieve oxygen generation system, using zeolite molecular sieve as the adsorbent. Based on the principle of pressure swing adsorption, the preferential adsorption of nitrogen by zeolite molecular sieve is used to realize the separation of oxygen and nitrogen and generate oxygen-enriched gas. Molecular sieve oxygen concentrator is generally composed of multiple molecular sieve beds, each bed works alternately and is in the state of adsorption and desorption respectively, so that the high-pressure gas from the engine passes through the adsorption and separation of molecular sieve beds to produce oxygen-enriched gas. The performance of molecular sieve oxygen c...
