Gas is input to burner, and it is tradition that the nitrogen oxygen segregation apparatus used, which includes at least one of molecular sieve bucket and oxygen permeable membrane,
Separation method, the traditional separation methods such as molecular sieve bucket and oxygen permeable membrane can obtain the oxygen-enriched air of high-purity, the disadvantage is that needing to mention
Air is driven to flow for biggish difference force, device is huge, complicated, energy consumption is big.
In recent years, domestic, occur some patent report (air about magnetic air separation tech successively in the world
In nitrogen, aqueous vapor, two carbon of dioxy and hydrogen etc. be weak inverse magnetism composition, they will receive slight repulsion in magnetic field
Power, and another important ingredient oxygen in air has strong paramagnetism, diamagnetism, paramagnetism molecule are only in gradient
It could be by the effect of power, draw of the diamagnetism molecule by the power for weakening direction along magnetic field strength, paramagnetism in magnetic field
Draw of the molecule by the power along magnetic field strength enhancing direction), but it is wherein most of because Technology design is unreasonable, without
It can be able to widely practically to apply, use the power on coil consumption electric energy as Japan Patent examined patent publication 42-15361 is proposed and produce
Raw high-intensity magnetic field recycles high-intensity magnetic field to carry out separation oxygen processed to the higher oxygen of magnetic susceptibility in air, but it is big with volume, power consumption
Height, and it is difficult to realize the shortcomings that commercially producing and applying.

Embodiment 2
Essentially identical with the structure of embodiment 1, as shown in fig. 6, difference is: ejector pipe 1 is corresponding in air intake end 11
Tube wall is in the shape of a trumpet, and equipment for magnetic separation 3 includes two blocks of opposite semi-circular shape magnetic of fixed cyclic and opposite surface polarity
Iron, such as third magnetic patch 311 and the 4th magnetic patch 312, the inner wall of third magnetic patch 311 and the 4th magnetic patch 312 has to enter along ejector pipe 1
The thickness that the corresponding tube wall in port end 11 is gradually increased.So that third magnetic patch 311 and the 4th magnetic patch 312 are far from air intake end
11 position has the thickness being gradually increased, in this way so that third magnetic patch 311 and the 4th magnetic patch 312 are far from air intake end 11
Position there is the thickness that is gradually increased, the internal diameter of such third magnetic patch 311 and the 4th magnetic patch 312 itself is also therewith changing and shape
At magnetic field gradient, bigger in the magnetic field gradient far from air intake end 11, the attraction that oxygen molecule is subject to can be stronger.
Magnetic field gradient in the present embodiment can reach 80-1000T/m, and oxygen enrichment percentage can reach 21%~23%, due to 311 He of third magnetic patch
Itself internal diameter of the 4th magnetic patch 312 can form magnetic field gradient, bigger in the magnetic field gradient far from air intake end 11, oxygen molecule
The attraction being subject to can be stronger.
