Description
Technical field
The utility model relates to medical equipment field, is specifically related to a kind of oxygen adsorption tower.
Background technology
Molecular sieve is one of important factor having a strong impact on the oxygenerator life-span, in prior art, when molecular sieve starts to occur efflorescence, the molecular sieve of efflorescence is due to smaller volume after efflorescence, molecular sieve mobility in space can increase, after flowing increases, surrounding sieve particle is under airflow scouring, increase the friction between particle, cause the efflorescence of more absorbent particles, this chain reaction can have a strong impact on the work-ing life of molecular sieve, simultaneously, after molecular sieve, molecular sieve reduces, molecular sieve reduces in the density of container, and a variety of causes causes the concentration of adsorb oxygen to reduce.
Utility model content
The utility model its object is to provide a kind of oxygen adsorption tower, realizes reducing molecular sieve, the concentration of supporting after improving absorption.
For realizing the utility model object, the technical scheme of employing is:
A kind of oxygen adsorption tower, comprise tower body, tower body is provided with inlet mouth and oxygen exhaust, it is characterized in that, the airintake direction of described inlet mouth is respectively arranged with sieve plate, wire cloth and isolating pad, is provided with activated alumina between described wire cloth and isolating pad; Be provided with contactor in described tower body, contactor top is fixedly connected with tower body top, and form annular inlet chamber outside contactor with inside tower body, annular inlet chamber communicates with inlet mouth, and contactor top is provided with air inlet sieve aperture; Degassing container is provided with in described contactor, be connected with bottom contactor bottom degassing container, degassing container top is provided with exhaust sieve aperture, and degassing container top is provided with opening, and stretch out tower body, between contactor inwall and degassing container outer wall, form adsorbent chamber; Be provided with push pedal between described contactor inwall and degassing container outer wall, push pedal lower end is provided with spring, and described spring bottom end is connected with bottom contactor, and its top is connected with push pedal lower end.
Further, described wire cloth is woven wire, economical and anti-static effect is good.
Further, the sieve aperture non-uniform Distribution of described degassing container middle and upper part.Be conducive to increasing air in the adsorbent chamber residence time, molecular sieve fully adsorbed, improves air utilization ratio.
The beneficial effects of the utility model:
One, by the design of the inlet chamber of annular, reach radial air inlet mode from outside to inside, make the intake pressure of adsorption tower even, and absorption is even, adsorption efficiency is high to coordinate ring-shaped ventilation mouth to reach; In addition, the high pressure draft that compressor is exported directly can not impact sieve particle, alleviates the efflorescence of molecular sieve, extends the work-ing life of oxygenerator.
Two, by being provided with push pedal and spring between contactor and degassing container, minimizing sieve particle with the flowing of air-flow, reduces intergranular friction in space, reduces molecular sieve speed, ensure the concentration of molecular sieve in adsorbent chamber in addition, avoid the concentration of oxygen to reduce.
Three, in channel of gas collection, design degassing container, outlet pressure is stablized, ensure that the pressure equilibrium in whole channel of gas collection, avoid the phenomenon that gas produces crossfire and molecular sieve " boiling " in the adsorbent chamber being filled with molecular sieve.
Four, by activated alumina and molecular sieve acting in conjunction, thus divided gas flow purity is improved.
