Technical Field

The invention relates to the technical field of centrifuges, in particular to a paramagnetic centrifuge.

Background

The centrifugal machine is a machine which uses centrifugal force to accelerate the separation of different materials to be separated. The centrifugal machine is widely applied to chemical, petroleum, food, pharmacy, ore dressing, coal, water treatment, ships and other departments.

For air separation, especially nitrogen and oxygen separation, the most common method is deep freezing, i.e. air is compressed and cooled to very low temperature, or air is liquefied by expansion and then separated in a rectification column. The method can prepare oxygen, nitrogen and rare gas, and the purity of the obtained gas product can reach 98.0-99.9%. In addition, the air is separated by adopting a molecular sieve adsorption method and is used for preparing oxygen-enriched air containing 70-80 percent of oxygen. In recent years, some countries have also developed techniques for separating air by solid membranes. Oxygen, nitrogen, argon, helium and other noble gases are used in a wide range of applications, so air separation units are widely used in the metallurgical, chemical, petroleum, mechanical, mining, food, military and other industrial sectors. The general disadvantages of the above-mentioned methods are the complexity of the operation and the high equipment costs. At present, however, no equipment for directly separating nitrogen and oxygen from air by using the centrifugal principle exists.

Therefore, the invention provides a paramagnetic centrifuge which separates nitrogen and oxygen in air in a centrifugal mode.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

As shown in fig. 1, a structure diagram of a paramagnetic centrifuge according to an embodiment of the present invention includes a housing 1 and a storage chamber 2, wherein the housing 1 has magnetism, and magnetic lines of force of the housing 1 are directed to the storage chamber 2; the storage chamber 2 encapsulates in just by power device drive rotation in the shell 1, be equipped with a plurality of separating element of equidistant distribution in the storage chamber 2 for realize the nitrogen oxygen separation under centrifugal force and magnetic force effect.

In practical application, air enters the storage chamber 2 and enters the separation assembly, the storage chamber 2 starts to rotate, and due to the fact that oxygen has paramagnetism and the mass of the oxygen is larger than that of the nitrogen, under the double effects of centrifugal force and magnetic force, the nitrogen and the oxygen are separated.

As shown in fig. 1, as a preferred embodiment of the present invention, the housing 1 and the storage chamber 2 are circular in cross section and are coaxially disposed.

As shown in fig. 1, as another preferred embodiment of the present invention, the separation assembly comprises a settling chamber 3 and a flotation chamber 4, the settling chamber 3 and the flotation chamber 4 being separated by a partition and being in communication at a position away from the rotational center of the storage chamber 2, the settling chamber 3 and the flotation chamber 4 being provided with an air outlet 8 and an air inlet 7, respectively, at a position close to the rotational center of the storage chamber 2. And the gas outlet 8 and the gas inlet 7 are both connected with corresponding gas pipes through high-speed rotary joints, and certainly, the gas pipes connected with the gas outlet 8 are provided with pumping holes 9, so that separated oxygen is conveniently stored.

In practical application, the air inlet 7 can input air to be separated into the separation assembly, the storage chamber 2 starts to rotate, in the settling chamber 3, when the air moves from a position close to the rotation center of the storage chamber 2 to the edge, the air does accelerated motion, because the mass of oxygen is larger than that of nitrogen, when the air moves to the top end of the separating piece, because the inertia of oxygen is larger than that of nitrogen, the oxygen can continuously move to the edge under the action of inertia, the effect of the flotation chamber 4 is the same as that of the settling chamber 3, along with the rotation of the storage chamber 2, the gas certainly has ascending moment, the gas ascends is in decelerated motion, and because of the effect of centrifugal force and magnetic force, the nitrogen with lighter mass moves to the rotation center of the storage chamber 2, and the separation effect is realized.

However, since air contains a small amount of moisture, the molecular weight of moisture is 18, and the molecular weight is smaller than that of nitrogen and oxygen, the centrifugal force applied to the air is small, and the water molecules are polar molecules and nitrogen and oxygen are nonpolar molecules, the binding force between the water molecules and the nitrogen and oxygen molecules is smaller than that of the nitrogen and oxygen molecules, and the water has diamagnetism, so that the water completely gasified in the air floats on the nitrogen and oxygen gas, and is more easily separated than the nitrogen.

As shown in fig. 1, as another preferred embodiment of the present invention, the side of the storage chamber 2 close to the housing 1 is made of a magnetic conductive material.

Preferably, the side of the reservoir 2 close to the housing 1 is made of a highly permeable material, which facilitates the introduction of the magnetic field into the reservoir 2 and towards its centre of rotation.

As another preferred embodiment of the present invention, as shown in fig. 1, the housing 1 is made of a ferromagnetic material or an electromagnet.

The strong magnetic material can be made of neodymium iron boron with high magnetic polarization strength, the magnetic field strength of 1.6T can be achieved through magnetic conduction design, the permanent magnet is beneficial to reducing energy consumption, and the strength, the model and the like of the specific magnet can be selected and used according to the energy consumption ratio.

The strong magnetic material can also be an electromagnet, the electromagnet has the advantage of controllable strength, but the electromagnet with the manufacturing cost more than 1.6T is higher, and the separation effect is not improved by increasing the centrifugal force by increasing the rotating speed.

In practical application, the magnetic conductive plate can be used to guide the magnetic force lines to the rotation center of the storage chamber 2, and the oxygen paramagnetism is used to increase the centrifugal force, wherein the paramagnetism is weak magnetism, and the oxygen paramagnetism is 3449 × 10^-6The paramagnetic attraction force is weaker than the binding force between nitrogen and oxygen molecules, unless liquefaction is performed, namely, the particle size of oxygen particles is increased, and the paramagnetic attraction force is still weaker than the binding force between the nitrogen and oxygen molecules, but because the difference of the molecular weights of the nitrogen and the oxygen is too small, the separation is performed by using a centrifuge which needs a large diameter and an ultrahigh rotating speed, namely, a large centrifugal force to separate the nitrogen and the oxygen, and the energy consumption is huge, so that the separation of the nitrogen and the oxygen is performed by using the combination of the paramagnetism and the centrifugal force of the oxygen, and the feasibility is strong.

As another preferred embodiment of the invention, as shown in fig. 1, the length of the partition is adjustable for adjusting the air strokes of the settling chamber 3 and the flotation chamber 4, so that the nitrogen-oxygen separation effect is adjustable.

In one aspect of the embodiment of the present invention, the partition 5 is a partition, and the length of the partition 5 from the edge of the storage chamber 2 determines the amount of communication between the settling chamber 3 and the flotation chamber 4, and the length of the partition may be adjusted in such a manner that the partition is detachable, and the nitrogen-oxygen separation effect is adjustable by replacing the partition.

As shown in fig. 1, as another preferred embodiment of the present invention, the number of the storage chambers 2 is several, and the storage chambers 2 are distributed along the axial direction of the housing 1, and when two adjacent storage chambers 2 are connected, the air inlet 7 of one storage chamber 2 is connected with the air outlet 8 of the other storage chamber 2.

After the storage chambers 2 are connected according to the above manner, multiple times of separation can be realized, and high-concentration oxygen is finally obtained, and the more the storage chambers 2 are connected in series, the higher the concentration is.

The invention utilizes the high paramagnetism of oxygen to improve the centrifugal force of the oxygen, and the total separation coefficient of the oxygen = the centrifugal force generated by the rotation of the storage chamber + the adsorption force generated by the oxygen paramagnetism + the repulsive force of the nitrogen diamagnetism + the repulsive force of the water molecules, thus increasing the centrifugal force of the oxygen molecules and reducing the centrifugal force of the nitrogen and the water vapor. In the case of water removal, water has diamagnetism, but in a completely gasified state, once water is condensed, weak diamagnetism roots cannot offset centrifugal force increased due to mass increase, while diamagnetism of water vapor and nitrogen is small and ignored in many places, but adsorption binding force between molecules plays a great role, so that diamagnetism repulsive force needs to be calculated, and diamagnetism is used for reducing the centrifugal force of water vapor and nitrogen.

The embodiment of the invention discloses a paramagnetic centrifuge, which utilizes the paramagnetism of oxygen to increase the centrifugal force of oxygen molecules and reduce the centrifugal force of nitrogen and water vapor so as to realize nitrogen-oxygen separation, and can select a plurality of storage chambers 2 to be connected in series, thereby ensuring that high-concentration oxygen is finally obtained through a plurality of nitrogen-oxygen separation modes.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
