Oxygen generation system and molecular sieve health state monitoring method thereof

Abstract

The invention provides an oxygen generation system and a molecular sieve health state monitoring method thereof. The method comprises the following steps: monitoring a pressure value of a molecular sieve; determining duration information when the pressure value reaches a pressure threshold; and determining the state of the molecular sieve according to the duration information. According to the technical scheme provided by the invention, the actual health state of the molecular sieve can be reflected according to objective indexes, and a user can accurately replace the molecular sieve when the performance of the molecular sieve is reduced, so that waste caused by advanced replacement is avoided, and meanwhile, danger caused by delayed replacement is avoided.

Description

technical field [0001] The invention relates to the technical field of oxygen production equipment, in particular to an oxygen production system and a method for monitoring the health status of molecular sieves thereof. Background technique [0002] Oxygen concentrator is a kind of equipment that can produce oxygen. According to the principle of oxygen production, it can be divided into molecular sieve oxygen concentrator, polymer oxygen-enriched membrane oxygen concentrator, electrolytic water oxygen concentrator and chemical reaction oxygen concentrator, etc. . In order to meet the needs of oxygen-demanding users for freedom of movement, there have been many portable oxygen concentrators, that is, users can carry them with them. The portable oxygen concentrators are small, simple and compact, and can meet the needs of users with oxygen at hand. [0003] In the adsorption portable oxygen generator, molecular sieves are consumables. Its service life is closely related to t...

Problems solved by technology

However, two molecular sieves are usually set up in portable oxygen concentrators to produce oxygen alternately. This general suggestion is only based on the manufacturer’s experience of the life of the molecular sieve. Users cannot know the real adsorption performance of each molecular sieve. There may be some If the performance of a molecular sieve is still very good, it should be replaced early, which will increase the user's use cost and waste resources; or, because the use environment is not good, the performance of the molecular sieve is already very poor, but it has not reached the time recommended by the manufacturer for replacement, which will give The use of aerobic users has buried potential safety hazards, resulting in poor user experience
