Description

Apparatus and Method For Separating Oxygen Using Electromagnetic field

The present invention relates to an oxygen separation device using an electromagnetic field, and more particularly, to an oxygen separation device that uses an electromagnetic field to separate oxygen in air, and simultaneously separates oxygen and nitrogen therefrom.

In recent years, superconducting and low temperature generation technologies have been greatly advanced, and superconducting magnets with excellent economical efficiency and operability are being put into practice. When such a superconducting magnet is applied to a magnetic separation device, a large amount of suspended particulates can be processed at high speed, energy is saved, and a small device can be processed in a small area.

In general, a superconducting magnetic separation device is a type of device for purifying wastewater or contaminated air generated in factories or homes using a superconducting magnet. After magnetizing a material to be separated in wastewater or air, a superconducting magnet When the object to be treated is passed through the magnetic filter inserted between, the material to be separated is adsorbed by the filter and separated.

The present invention is to separate oxygen from the air, and the air is composed of about 78% nitrogen (N ₂ ) and about 21% oxygen (O ₂ ), and there are various methods for separating air into nitrogen and oxygen. have.

In particular, a method of separating using activated carbon or zeolite by using the size difference between nitrogen and oxygen molecules has been commercialized. However, this increases the purity by repeating compression and expansion at high pressure, and there is a problem in that productivity is low, such as a large amount of air to be used compared to the amount of gas to be separated, and a lot of time required for the process.

On the other hand, nitrogen has a very weak diamagnetic (-0.43 × 10 ^-6 cm ³ /mol), and oxygen has a large susceptibility (108 × 10 ^-6 cm ³ /mol) among paramagnetic materials. Therefore, under a high magnetic field, nitrogen is hardly affected, but oxygen is attracted in the direction of a strong magnetic field. Of course, oxygen is expected to be effective in the high magnetic field generated by superconducting magnets because its susceptibility is much smaller than that of strong magnetic materials such as Fe, Ni, and Co.

Accordingly, Korean Patent No. 1215554 uses a superconducting magnetic separation device and a non-magnetic pipe including a magnetic filter wire to transfer air at a higher speed compared to the existing device, and the gas and oxygen concentrations of the gas and oxygen are high compared to the natural state. An oxygen superconducting magnetic separation device that can be separated into gas at the same time has been proposed. In Korean Utility Model Registration No. 0355913, an oxygen generating unit that separates and condenses oxygen in the atmosphere and an oxygen molecule that has passed through the oxygen generating unit is a powerful reactive oxygen group. An oxygen generator consisting of a magnetization generator that converts into molecules and supplies them to the outside has been proposed.

However, the above documents are a method of adsorbing and separating magnetized oxygen into a magnetic filter wire or a magnetization generator, and it is difficult to efficiently separate from air by adsorbing oxygen whose kinetic energy rapidly changes according to temperature to the filter with only magnetic force. There was a problem.

In the present invention, the main body 110 contains oxygen (short dotted line) and oxygen separated through an inlet 111 through which air (solid line) can be introduced, and a magnetization generator 120 and a discharge module 130 to be described later. A discharge port 112 through which the separated air (thick dotted line) is discharged is formed, and the main body is formed as one body 115 until the discharge port 112, and among the discharge ports 112, the magnetization generating unit 120 At the end of the end, preferably at the distal ends of the permanent magnets 121 and 122 of the magnetization generating unit 120, the main body is separated by a partition wall 113 to extend into two bodies. Accordingly, in the main body, air is introduced through the inlet 111 of one body, and the oxygen separated and treated through the magnetization generating unit and the discharge module is discharged to the oxygen discharge unit (O ₂ rich, 112a) of the two bodies, The air from which oxygen is separated is discharged to the nitrogen discharge unit (N ₂ rich, 112b).

At this time, the body 115 and the partition wall 113 of the main body may be non-magnetic materials that are not magnetized so as not to affect the magnetization generating unit, and for example, may be plastic, ceramic, glass, etc., and the shape of the main body is a hexahedral body. , It can be manufactured in a variety of shapes such as a tubular shape, but a hexahedral shape is preferable in terms of installing the magnetization generator and the discharge module inside the body and in the upper and lower portions.

In addition, the main body 110 further includes a magnetic filter 114 made of ferritic stainless steel, an adsorbent, a separator, etc. to the oxygen discharge part 112a through which oxygen is discharged among the two bodies separated by the partition wall 113. It may be a magnetic filter 114 made of a ferritic stainless material capable of maintaining magnetization to oxygen so that oxygen can be separated and adsorbed from the air to be discharged, and preferably oxygen is stably discharged through the oxygen discharge unit 112a. .

In the present invention, the magnetization generator 120 is provided with permanent magnets 121 and 122 respectively on the upper and lower outer circumferential surfaces of the main body 110 described above to magnetize oxygen in the air introduced into the main body, and a discharge module to be described later. By forming a magnetic field in the current generated at (130), it plays a role of moving oxygen in the direction of a force (Lorentz force) perpendicular to the direction in which the electric charge moving in the magnetic field moves. At this time, nitrogen in the air is hardly affected and oxygen can be separated from the air.

The permanent magnets 121 and 122 of the magnetization generating unit 120 are arranged in parallel with the N-pole permanent magnet 121 and the S-pole permanent magnet 122 on the upper and lower outer circumferential surfaces of the main body, Allow air to pass inside the body of the body. At this time, the arrangement method of the N-pole permanent magnet 121 and the S-pole permanent magnet 122 is to place an N-pole permanent magnet on the upper outer circumference of the main body, or an S-pole permanent magnet, and N It is also possible to place a pole permanent magnet, or a south pole permanent magnet.

The permanent magnets 121 and 122 can be used without limitation as long as they are magnetic permanent magnets capable of magnetizing oxygen passing through the body, and can be used by adjusting to the size of the body, preferably having a magnetic force of 1,500 G or more, more preferably It may be between 2,000 G and 15,000 G. If the magnetic force is less than 1,500 G, there may be a problem that oxygen cannot be dragged in the direction of the electromagnetic field due to insufficient magnetization of oxygen.

In the present invention, the discharge module 130 is mounted inside the main body and is spaced apart from the first discharge unit 131 and the first discharge unit 131 charged with a negative electrode and arranged in parallel, and charged with a positive electrode. The second discharge unit 135 is provided.

The first discharge unit 131 is made of a metallic material having good electrical conductivity, such as aluminum, copper, iron, and alloys thereof, and the shape thereof is an open type so that the flow of air can pass without being disturbed, as described later. Since a number of pointed needles 132 are formed toward the center of the second discharge plate hole 136 that is formed, electric charges can be efficiently transferred to the second discharge plate even at a relatively low voltage.

The second discharging unit 135 is spaced apart from the first discharging unit 131 and arranged in parallel, and aluminum, copper, iron, etc., so that the current generated from the first discharging unit 131 flows well. It is composed of a metallic material such as an alloy of, and preferably may be composed of aluminum in terms of durability. 1 to 6 show the second discharge unit 135 in a flat plate shape, but it is possible to form an electric field by receiving a current (charge) generated from the first discharge unit 131 without interfering with the flow of air. Any form can be used as long as it exists.

In addition, the second discharge unit 135 drills a hole 136 with an area corresponding to the minimum area of the pointed needle 132 of the first discharge unit to enable the flow of air, thereby reducing the back pressure load in the device to allow the flow of air. Help reduce energy consumption. In this case, the distance between the second discharge unit and the first discharge unit is a distance between the second discharge unit 135 and the needle unit 132 protruding from the first discharge unit, and may range from 0.1 cm to 1 cm. If the distance between the second discharge part and the needle part 132 protruding from the first discharge part is less than 0.1 cm, a short-circuit occurs and a problem of shortening the life of the discharge module occurs. If it is exceeded, an electric field cannot be formed, resulting in a problem in that oxygen separation from air cannot be efficiently performed.

The discharge module 130 provided with the first discharge unit and the second discharge unit as described above is arranged in a vertical direction with the magnetization generating unit 120 to form a strong electric field in the vertical direction of the magnetic field formed from the magnetization generating unit, thereby forming a paramagnetic air. Oxygen in the medium (short dotted line) moves in one direction strongly in the direction of the Lorentz force of the powerful electromagnetic field due to the Hall Effect.

For example, as shown in Figs. 1 to 6, a first discharge unit 131 is disposed on the left side of the main body 110, and a second discharge unit 135 is disposed on the right side of the main body to face the disposed first discharge unit. When a voltage is applied to the first discharge unit 131 and the second discharge unit 135 through the power supply unit 140, current flows from the first discharge unit 131 to the second discharge unit 135. And an electric field is formed. At this time, if the N-pole permanent magnet 121 is positioned under the outer circumferential surface of the main body 110, and the S-pole permanent magnet 122 is positioned on the upper outer circumferential surface of the main body, a magnetic field is formed in a direction perpendicular to the current formed in the discharge module 130. Oxygen in the air (short dotted line) moves toward the oxygen discharge part 112a by receiving the Lorentz force to the maximum without changing energy.

The power supply unit 140 for supplying power to the high voltage discharge module 130 increases the voltage to the first discharge unit 131 and the second discharge unit 135 of the discharge module at 6 V or higher, preferably 9 V to 30 V is applied to charge the first discharge portion to the negative electrode and the second discharge portion to the positive electrode. If the voltage of the power supply unit is less than 6 V, the voltage cannot be applied to the discharge module, and an electric field cannot be formed in the main body.

In order to improve the oxygen separation efficiency, the oxygen separation device 100 according to the present invention includes a permanent magnet of the magnetization generating unit 120 and a first discharge unit and a first discharge unit of the discharge module 130 in the main body as shown in FIGS. 4 to 6. 2 It is possible to arrange a plurality of discharge units at predetermined intervals. At this time, the magnetization generating unit and the discharge module disposed in the main body may be adjusted according to the space in which they are disposed, and preferably 2 or more, less than 10, and more preferably 2 to 5.

In another aspect, the present invention relates to an oxygen separation method for separating oxygen from air using the above-described oxygen separation device.

In the oxygen separation method according to the present invention, a voltage is applied from the power supply unit 140 of the oxygen separation device 100 to the discharge module 130 to charge the cathode to the first discharge unit 131, and the second discharge unit. When the positive poles are respectively charged to 135, a current flows between the charged first and second discharge units, and at the same time, a magnetic field in the permanent magnets 121 and 122 of the magnetization generators respectively mounted on the upper and lower parts of the outer circumferential surface of the main body It is formed in the vertical direction of the formed current. At this time, of the air (solid line) introduced through the main body inlet 111, only oxygen (short dotted line), which is a paramagnetic substance, is dragged in one direction under the influence of the Lorentz force, and the main body separated into two by the partition wall 113 The body is discharged in the direction of the oxygen discharge part 112a located in the Lorentz force direction, and the air separated from the oxygen (thick dotted line), that is, nitrogen is separated and discharged to the nitrogen discharge part 112b in the other body.

In addition, the oxygen separation method according to the present invention further improves the separation of oxygen from the air, and in order to increase the purity of the separated oxygen, a magnetic filter 114 is provided inside one body from which oxygen is discharged among two bodies separated by a partition wall. , An adsorbent, a separator, etc. may be additionally included to separate and adsorb oxygen from the air. In addition, a plurality of magnetization generators 120 and voltage modules 130 of the oxygen separation device are placed on the main body 110 at predetermined intervals. Can be placed in dogs.

Therefore, the oxygen separation method according to the present invention creates a strong electric field in the vertical direction of a strong magnetic field, so that oxygen in the air is strongly focused in the direction of Lorentz force without external influences such as temperature through the Hall effect. It can be separated from the inside, and air is introduced into the device due to natural convection through the movement of oxygen, so there is no need for a compressor or fan to inject air, and separation of oxygen is possible without external influences such as temperature. As a result, the oxygen separation device can be used in a narrow space because it can compensate for the disadvantages of the existing oxygen separation device and reduce the volume and cost.

Hereinafter, the present invention will be described in more detail through examples. These examples are for illustrative purposes only and should not be construed as limiting the scope of the present invention by these examples.
