Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a small-scale oxygen generator system with low energy consumption. Background technique [0002] Oxygen concentrator is a kind of machine for producing oxygen. Some small household oxygen concentrators generally use molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. The molecular sieve discharges the adsorbed nitrogen back into the ambient air during decompression, and can absorb nitrogen and produce oxygen during the next pressurization. The whole process is a periodic dynamic cycle process, and the molecular sieve does not consume. [0003] The following problems also exist in existing small-sized oxygen generator: [0004] 1. The heat generated after th...

Problems solved by technology

[0004] 1. The heat generated after the air is pressurized will cause the temperature of the high-pressure pipeline to continue to rise. Traditional equipment usually uses a fan to blow the high-pressure pipeline to cool down the high-pressure pipeline and the high-pressure gas in the pipeline. Cooling, this method is not effective and the heat still exists inside the shell of the equipment, which will cause the ambient temperature in the shell of the equipment to rise and affect the normal operation of the equipment;

[0005] 2. Traditional equipment generally uses an air compressor to absorb ambient air as an oxygen-generating material, while the filter device that comes with the existing air compressor is generally installed directly on the air intake pipe of the air compressor. It is not self-cleaning, and the filter element and filter screen need to be replaced frequently. When the filter element or filter screen is clogged, it is easy to cause problems such as reduced air intake and dust accumulation on the impeller during operation of the air compressor

In view of this problem, under normal circumstances, the filter element must be shut down, which increases the maintenance cost and maintenance workload of the air compressor, and the service life of the equipment will also be affected
