Technical Field
The utility model belongs to the technical field of oxygen concentrators, and particularly relates to a molecular sieve cylinder.
Background
The oxygen concentrator is a common oxygen collecting device, and the working principle is that zeolite molecular sieve is used as adsorbent, and nitrogen in air is adsorbed and released by using the principles of pressure adsorption, depressurization and desorption, so that the oxygen collection and concentration improvement are completed. The zeolite molecular sieve has super strong adsorption performance, and the zeolite molecular sieve has strong adsorption performance because molecular attraction acts on the surface of a solid to generate a surface force, when fluid flows, some molecules in the fluid collide with the surface of an adsorbent due to irregular movement, and molecular concentration is generated on the surface, so that the number of the molecules in the fluid is reduced to the purposes of separation and removal. Since adsorption does not change chemically, zeolite molecular sieves have adsorption capacity as long as they try to drive away molecules concentrated on the surface, which is the reverse of adsorption, known as the desorption or regeneration process. Zeolite molecular sieves also have strong ion exchange properties, which refer to the compensatory cation exchange process to the outside of the framework. The pore size of the zeolite molecular sieve can be changed by ion exchange, thereby changing its properties. After ion exchange, the number, the size and the position of cations are changed, for example, after high-valence cations exchange low-valence cations, the number of cations in the zeolite molecular sieve is reduced, and position vacancies are often caused to enlarge the aperture of the zeolite molecular sieve; and after ions with larger radius exchange ions with smaller radius, holes of the ions are easily blocked to a certain extent, so that the effective aperture is reduced.
The existing molecular sieve tube has the following defects: the internal zeolite molecular sieve is easy to wet to cause failure, so that the service life of the zeolite molecular sieve is reduced.
