Description
Technical Field
The utility model relates to an oxygen dehumidification mechanism of oxygenerator especially relates to a hot blowing dehumidification mechanism of oxygenerator.
Background
The oxygen generator adopting the molecular sieve pressure swing adsorption principle generally needs to remove moisture contained in compressed air at the front section of the molecular sieve, otherwise, the molecular sieve can cause the strength reduction of the molecular sieve after absorbing the moisture in the air, and the molecular sieve can be rapidly pulverized under the condition of the alternate change of the internal pressure of the molecular sieve cylinder, so the service life of the oxygen generator is greatly shortened. Meanwhile, when the water content of the prepared oxygen is high, the inner wall of the gas storage steel cylinder is corroded and damaged.
In addition, for medical oxygen produced by a small oxygen generator, the national standard has a strict standard on the moisture content in the produced oxygen, so that the moisture in the compressed air is very necessary to be removed in the oxygen production process.
For a common oxygen generator, a freeze-drying machine can be used for water removal, but the volume of the freeze-drying machine is large, only a large molecular sieve central oxygen generation system is matched with the freeze-drying machine and then water removal is carried out through adsorbent adsorption, and a household or medical small molecular sieve oxygen generator directly adopts an adsorbent adsorption water removal mode. However, the direct adsorption type water removal method cannot continue adsorption after saturated adsorption, so that the service life of the water removal device can be obviously reduced in areas with higher humidity. The water removal is also called dehumidification, the effect is the same, the industry is generally called dehumidification because the water content in the oxygen is not high, and the dehumidification is adopted to replace the water removal in all the following.
For household or medical small-sized molecular sieve oxygen generator, at present, there is also a centrifugal dehumidification mode, i.e. compressed air is filled into a centrifugal separation tank, and because the specific gravity of the water in the air is greater than that of the air, the water can be attached to the inner wall of the centrifugal separation tank and flows down along the inner wall, and then flows into a water storage tank.
The traditional centrifugal dehumidification mode avoids the problem that the adsorbent cannot continuously adsorb water after being saturated, but has the following defects: on one hand, the water storage tank needs to be connected below the centrifugal separation tank, so that not only is the space occupied, but also a special interface is needed for matching, the processing difficulty is increased, and the attractiveness is influenced; on the other hand, what is more important is that the water storage tank needs to be taken out and poured out when the water storage tank is nearly full, which not only wastes time and labor, but also easily causes the water in the water storage tank to overflow due to forgetting or being full in advance, and the like, thereby causing the consequences of equipment corrosion damage, safety accidents caused by electric leakage and the like.
