Portable oxygenerator

Abstract

The invention relates to the technical field of oxygenerators, in particular to a portable oxygenerator, which comprises a shell and an oxygenator main body placed in the shell. The oxygenator main body comprises two parallel adsorption towers, which are flat cylindrical structures and filled with molecular sieves in the inner cavities, the two adsorption towers are erected on both sides of the oxygenator main body oppositely, a compressor, an oxygen storage tank, a circuit board, an air intake module and a corresponding bracket and connection pipeline are placed between the two adsorption towers, air distribution structures are disposed between all adsorption tower air inlets and the molecular sieves, the air distribution structures include air distribution nozzles and flow equalization sieve plates for air distribution and flow equalization, so that the gas entering the adsorption towers can achieve a uniform pressure in the adsorption towers. The portable oxygenerator provided by the invention has the beneficial effects of compact space structure, small size, light weight and easy carrying, also the atmospheric pressure in the adsorption towers is uniform and the molecular sieveutilization rate is high.

Description

technical field [0001] The invention relates to the technical field of oxygen generators, in particular to a portable oxygen generator. Background technique [0002] At present, most oxygen generators on the market use pressure swing adsorption (PSA) circular adsorption tower oxygen generators. Pressure swing adsorption oxygen generators, also known as molecular sieve oxygen generators, are based on pressure swing adsorption (PSA) technology. , a new device for extracting oxygen from the air. It uses molecular sieve physical adsorption and desorption technology to fill the oxygen generator with molecular sieve, which can absorb nitrogen in the air when pressurized, and the separated unadsorbed oxygen is collected, and after purification, it becomes high-purity oxygen. The specific working process is that after the compressed air is purified by the air purification dryer, it enters the adsorption tower through the switching valve. In the adsorption tower, nitrogen is adsorb...

AI Technical Summary

Problems solved by technology

In the existing oxygen generators on the market, the high-pressure air enters the adsorption tower and directly passes through, resulting in a straight-through tunnel effect and side wall effect. The utilization rate of molecular sieves is low, and the probability of molecular sieve pulverization is increased; and the adsorption towers are cylindrical. shape, low space utilization, and the overall structure is relatively bulky, so it is generally used indoors or outdoors, and it is not convenient to carry and use
