Description

Technical Field

[0001] The utility model relates to the technical field of separation and purification, in particular to a radio frequency plasma separation and purification system using a hydrogen energy storage fuel cell as power. Background Art

[0002] Separation and purification refers to separating impurities from a mixture to improve its purity. It mainly includes chemical purification and physical purification methods. Among them, radio frequency plasma spheroidization technology, as a kind of physical separation method, can be well applied to the separation and purification of high-melting-point metal impurities; radio frequency plasma spheroidization technology is to heat the raw materials through the high temperature of plasma, so that the high-melting-point metal is melted by heat, and the low-melting-point impurities are vaporized and burned. The molten high-melting-point metal is rapidly solidified under the combined action of surface tension and extremely high temperature gradient to form a spherical powder, which is then separated from the impurities. Radio frequency plasma spheroidization technology can convert the raw materials from irregular shapes into high-quality spherical powders with high sphericity and good fluidity while separating and purifying, so it has gradually become one of the methods for separating and purifying high-melting-point metals, ceramics, and composite materials.

[0003] In the prior art, the radio frequency plasma separation and purification process requires a high-power current to ionize the inert argon gas to increase the ambient temperature. The argon gas brings the powdered raw materials to be separated and purified into the plasma generator, and completes the separation of high-temperature materials and low-temperature impurities in a high-temperature heating environment. After the high-temperature material is melted, it passes through the temperature gradient in the cooling chamber and the surface tension to form round particles that gather in the powder collection tank. The utility model proposes a radio frequency plasma separation and purification system powered by a hydrogen energy storage fuel cell to solve the above-mentioned technical problems. The above-mentioned radio frequency plasma separation and purification technology requires a large amount of electricity and a large amount of argon gas, and the cost of separation and purification remains high.

[0012] The radio frequency plasma separation and purification system powered by hydrogen energy storage fuel cells operates as follows:

[0013] S1: Hydrogen is ionized in a plasma jet by a high voltage electric field to form a high enthalpy plasma;

[0015] S3: The molten raw materials are formed into powder with uniform particles under the action of temperature gradient and surface tension; the impurities that are gasified or burned are sucked out of the plasma jet by negative pressure, completing the separation of raw materials and impurities;

[0016] The cooling process of the equipment is achieved by introducing cooling medium into the jacket on the outer wall of the high-temperature equipment.

[0017] Wherein, the high-voltage electric field in step S1 is supplied by industrial power supply equipment and / or SOFC-SOEC batteries, and the SOFC-SOEC batteries include SOFC fuel cells and SOFC electrolytic cells; when the industrial electricity cost is low, the industrial power supply ratio is increased and the SOFC-SOEC battery power supply ratio is reduced. When the industrial electricity cost is low, the SOFC-SOEC battery is powered, hydrogen is prepared by water electrolysis reaction, and the hydrogen is stored and collected to provide hydrogen for the radio frequency plasma separation and purification system and supply hydrogen gas for the SOFC fuel cell; when the industrial electricity cost is high, the industrial electricity consumption ratio is reduced and the SOFC-SOEC battery power supply ratio is increased.

[0018] Optionally, hydrogen can be introduced into the plasma jet to prevent the raw materials from being oxidized under high temperature conditions through the hydrogen atmosphere.

[0021] The working principle is as follows: through the reversibility of the hydrogen production process of hydrogen fuel cell power generation, according to the changes in industrial electricity prices during peak and off-peak periods, when the electricity rate is low, the industrial electricity consumption is increased while the industrial electricity is used to electrolyze water to produce hydrogen. The stored hydrogen can be used to supply hydrogen to the fuel cell and the plasma injector, so as to maximize the internal supply ratio of hydrogen sources. On the one hand, off-peak electricity consumption solves the electricity storage pressure of the national power grid, and on the other hand, it effectively reduces the separation and purification costs. By recycling the heat generated in the separation and purification process and the heat released by the SOFC fuel cell and utilizing it in the water hydrogen production process of the SOEC cell, the input of external energy is reduced, further reducing the operating cost of the system. Furthermore, the water generated by the SOFC-SOEC cell can be used in the high-temperature cooling process, and the water cycle inside the system is reused.

[0023] The characteristic of this utility model patent is that it organically combines the SOFC-SOEC hydrogen fuel cell / electrolyzer with the high-purity powder making system, and combines the high energy consumption (electricity and hydrogen) of the powder making system with the reversible characteristics of the solid oxidation battery electrolyzing water to produce hydrogen and hydrogen to generate electricity, so as to realize the low-cost acquisition of electricity and hydrogen in the separation and purification system. At the same time, the large amount of heat generated is in turn supplied to the SOEC electrolytic hydrogen, reducing the cost of hydrogen production and power generation. The utility model can effectively reduce the cost of separating and purifying high-melting-point raw materials; the product can be separated and purified while improving the performance of use; hydrogen can be used as a protective gas and can also be supplied to fuel cells for power generation.

[0036] Specifically, such as Figure 2 As shown:

[0037] The power supply module 1 includes a SOFC-SOEC battery 1-1, an industrial power unit 1-2, an inverter 1-3, and a high-frequency induction power supply 1-4.

[0041] Specific implementation case 2:

[0042] Based on the specific implementation case 1, the radio frequency plasma separation and purification system powered by a hydrogen energy storage fuel cell may also adopt one or more of the following preferred technical solutions:

[0043] like Figure 2 , Figures 3 to 6As shown, the plasma injection module 2 includes a plasma injector 21, a support frame 22, an air distribution plate 23, a hand wheel 24, and a fan 25.

The clamping ring 231 is translated along the slot of the support frame 22 to install the air distribution plate 23 on the inner side of the support frame 22. The clamping ring 231 is rotatably connected to the side of the air distribution plate 23 through an axis, and one end of the rotating shaft 232 is directly fixed to the hand wheel 24 (as shown in FIG. Figure 6 As shown, one end of the rotating shaft 232 passes through the plasma injector 21, and the end of the rotating shaft 232 is threadedly connected to the hand wheel 24, and the air distribution plate 23 is rotated by turning the hand wheel 24) or indirectly transmitted (for example, one end of the rotating shaft 232 is provided with a gear, the hand wheel 24 is rotatably connected to the plasma injector 21 and the end of the hand wheel 24 located in the inner cavity of the plasma injector 21 is provided with a gear, and the two gears are meshed and connected, which is not drawn in the drawings), and the inclination angle of the air distribution plate 23 is changed by turning the hand wheel 24; the plasma injector 21 is provided with a medium-sized powder channel 91 above the installation position of the air distribution plate 23, and the powder collection tank 9 is installed at the outlet end of the medium-sized powder channel 91, and the powder collection tank 9 and the outer side of the medium-sized powder channel 91 are both connected to the cooling module 8, and the fan 25 is connected to the plasma injector 21 and the connection position is located below the air distribution plate 23.

A small amount of large-size spherical powder rises with the air flow, and most of it falls back on the upper surface of the air distribution plate 23 under the action of the internal air flow and its own gravity. By regularly rotating the hand wheel 24, the large-size spherical powder deposited on the upper surface of the air distribution plate 23 falls into the coarse powder collecting tank 6; a small amount of large-particle powder rises under the action of wind and enters the auxiliary coarse powder collecting tank 10 from the auxiliary coarse powder collecting channel 101 (depending on the different impurity particle sizes, some larger-size impurity powders can also be collected, which depends on the actual situation and is not a limitation on the collected materials here), and impurities with lower melting points form medium-size spherical powder which passes through the medium-size powder channel 91 and enters the powder collecting tank 9 for deposition and collection, and some smaller particles are collected through the fine powder collecting tank 7. At this point, the raw materials doped with one or more impurities are separated, purified and formed into high-purity spherical powder through the radio frequency plasma separation and purification system. The performance of the raw materials themselves is optimized during the separation and purification process. The separated impurities can also be further separated and purified before use, depending on the required purity.
