Problems solved by technology

On the one hand, most of the traditional oxygen production uses zeolite molecular sieves to produce oxygen by pressure swing adsorption. The higher the pressure, the stronger the adsorption capacity, but as the pressure increases, the temperature inside the shell will also increase. The increase will reduce the adsorption capacity of the zeolite molecular sieve, and the device cannot be used to absorb oxygen to the greatest extent; on the other hand, the air inlet is directly aligned with the middle of the zeolite molecular sieve, which will easily cause the gas to gather in the middle, causing the middle area to enter the adsorption saturation in advance State, slow adsorption around; low efficiency of oxygen production, insufficient adsorption of zeolite molecular sieve, etc.

Description

technical field [0001] The invention belongs to the technical field of oxygen generators, and in particular relates to a thermodynamic model-based pressure swing adsorption device. Background technique [0002] At present, there are more and more types of oxygen generators on the market, but there are still many problems. On the one hand, most of the traditional oxygen production uses zeolite molecular sieves to produce oxygen by pressure swing adsorption. The higher the pressure, the stronger the adsorption capacity, but as the pressure increases, the temperature inside the shell will also increase. The increase will reduce the adsorption capacity of the zeolite molecular sieve, and the device cannot be used to absorb oxygen to the greatest extent; on the other hand, the air inlet is directly aligned with the middle of the zeolite molecular sieve, which is easy to make the gas gather in the middle, causing the middle area to enter the adsorption saturation in advance State...
