Utilize magnetic force to realize that the principle of oxygen concentration in the air and method describe to the present invention below.
The main component of air is oxygen and nitrogen, also has a spot of carbonic acid gas, water vapor and other micro-rare gas element.In the middle of these gases, the volume susceptibility of oxygen is+146 * 10
-6("+" represents that this gas is paramagnetism gas), this class gas is consistent with the magnetic field gradient direction in the direction of the magnetic force that gradient magnetic is subjected to.On the contrary, the volume susceptibility of nitrogen is-0.58 * 10
-6, carbonic acid gas be-0.84 * 10
-6, water vapor be-0.58 * 10
-6("-" represents that this gas is diamagnetism gas), the direction of the magnetic force that this class gas is subjected in gradient magnetic is opposite with the magnetic field gradient direction.This shows that not only the volume susceptibility of oxygen is more a lot of greatly than the volume susceptibility of other gas in the air, and its magnetic is opposite.This character of oxygen makes utilizes gradient magnetic to realize that the enrichment of oxygen becomes possibility in the air.
The method of utilizing magnetic force to realize oxygen concentration in the air of the present invention is to make air by there being the space of gradient magnetic on the border, utilize gradient magnetic that the reactive force that oxygen molecule produces is strapped in the airborne oxygen molecule that is flowing in the magnetic field space, in magnetic field space, form the enrichment region of oxygen, the gas in this zone is drawn to obtain oxygen-rich air.After air enters magnetic field space from gas inlet, will from around open boundary flow out.When air flows out magnetic field space, because boundary exists direction to point to the magnetic field gradient of magnetic field space inside, oxygen molecule (paramagnetism molecule) will be subjected to pointing to the magnetic force of magnetic field space inside, so it goes out stream and is fettered; Nitrogen molecule and other gas molecule (diamagnetism molecule) then are subjected to pointing to the magnetic field force of magnetic field space outside, therefore can flow out magnetic field space smoothly.So just obtain enrichment at the inner oxygen molecule of magnetic field space.
Magnetic field space of the present invention is formed relatively by two permanent magnet heteropoles, and boundary forms the magnetic field gradient that points to magnetic field space inside around magnetic field space.Two permanent magnets distance range apart is 0.1mm～1000mm.
The present invention be utilize " the magnetic sieve " of gradient magnetic thus effect is strapped in airborne oxygen molecule the enrichment of realization oxygen in the magnetic field space, it changes the flow direction of oxygen in the fluidizing air and realizes that the method for oxygen concentration is different the magnetism that oxygen produces with relying on gradient magnetic, though the both has utilized the oxygen nitrogen molecule can be subjected to the opposite magneto motive principle of direction in gradient magnetic, but the former can effectively avoid in the oxygen concentration process, gas turbulence, the weakening effect of the pedesis of gas molecule and concentration diffusion couple oxygen concentration.
The present invention has the following advantages:
1. can carry out oxygen concentration at normal temperatures and pressures, do not need liquefaction of air, thereby energy consumption be little, cost is low;
2. required magnetic field is produced by permanent magnet, not other consumed energy, simultaneously, and the permanent magnet material low price, range of choice compares broad;
3. the major parts that is used for oxygen concentration does not exist mechanical wear, long service life;
