Description
Technical Field
The invention relates to an oxygen dehumidifying mechanism of an oxygen generator, in particular to a hot blowing dehumidifying mechanism of the oxygen generator.
Background
The oxygen generator adopting the molecular sieve pressure swing adsorption principle generally needs to remove water in compressed air at the front section of the molecular sieve, otherwise, after the molecular sieve absorbs water in air, the molecular sieve strength can be reduced, and under the alternate change of the internal pressure of the molecular sieve cylinder, the molecular sieve can be rapidly powdered, so that the service life of the oxygen generator is greatly shortened. Meanwhile, when the water content of the produced oxygen is high, corrosion damage can be caused to the inner wall of the gas storage steel cylinder.
In addition, for medical oxygen produced by a small-sized oxygen generator, the national standard has strict standards on the moisture content in the produced oxygen, so that the removal of the moisture in the compressed air is very necessary in the oxygen production process.
For general oxygenerator, can use the cold drier to remove water, but the cold drier is relatively big, only the large-scale molecular sieve center oxygen generation system can be supporting to have the cold drier after again pass through the drier and adsorb the dewatering, and domestic or medical small-size molecular sieve oxygenerator then directly uses the adsorbent to adsorb the dewatering mode. However, the direct adsorption type water removal mode cannot continue adsorption after adsorption saturation, so that the service life of the water removal device can be obviously reduced in areas with high humidity. The water removal is also called dehumidification, and the effect is the same, and the moisture content in oxygen is not high, so the industry is generally called dehumidification, and all matters below adopt dehumidification to replace water removal.
In the case of small molecular sieve oxygenerator for household or medical use, there is a centrifugal dehumidifying method, i.e. compressed air is filled into a centrifugal separating tank, and because the water content in the air is greater than the water content in the air itself, the water will adhere to the inner wall of the centrifugal separating tank and flow down along the inner wall, and then flow into a water storage tank.
The conventional centrifugal dehumidification method avoids the problem that the adsorbent cannot continuously adsorb water after saturation, 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 can space be occupied, but also a special interface is needed for matching, the processing difficulty is increased, and the attractiveness is influenced; on the other hand, more importantly, the water storage tank needs to be taken out and poured out when the water storage tank is nearly full, so that time and labor are wasted, water in the water storage tank is easy to overflow due to forgetting or advanced water filling, equipment is damaged due to corrosion, safety accidents are caused due to electric leakage, and the like.
