Description

Technical Field

[0001] This invention relates to the field of oxygen production technology, and in particular to a liquid silver oxygen production device and method. Background Technology

[0002] Oxygen is a fundamental substance for human survival and an important natural resource, widely used in metallurgy, chemical industry, medicine, and aerospace. Current methods for oxygen production mainly include physical, chemical, and electrochemical methods.

[0003] Physical methods mainly include cryogenic oxygen production, pressure swing adsorption (PSA), and membrane separation. Cryogenic oxygen production is suitable for large-scale production, but it is complex to operate, slow to start up, has strict requirements, and is costly. PSA and membrane separation are not suitable for large-scale oxygen production. Chemical methods produce oxygen rapidly and with high purity, but they are also costly, have complex reaction devices, poor safety, and are prone to pollution. Electrochemical methods, represented by water electrolysis, produce oxygen with high purity and stable performance, but consume a lot of electricity, and the byproduct hydrogen poses a flammable and explosive safety hazard.

[0004] Research has found that molten silver in the air can absorb approximately 22 times its own volume of oxygen, while nitrogen, rare gases, and carbon dioxide in the air are poorly soluble in silver. By using air as a raw material and utilizing the physical property of liquid silver to selectively dissolve oxygen from the air and release it under reduced pressure, it is possible to achieve high-purity, low-pollution, cyclical oxygen production.

[0005] The solubility S of a gas in a liquid metal is related to the temperature of the metal and the partial pressure P of the gas. When the temperature is constant, the solubility model is:

[0006]

[0007] In the formula, S is the solubility of the gas in the metal; P is the partial pressure of the gas; K P This is the equilibrium constant.

[0008] Liquid silver oxygen production model, such as Figure 6 As shown, different partial pressures of oxygen correspond to different Ag-O equilibrium systems. When the dissolved oxygen liquid surface is in contact with air, the partial pressure of oxygen at the dissolved oxygen liquid surface is P1, which is greater than the oxygen pressure P2 in the oxygen-generating chamber. Because the solubility of liquid silver for oxygen varies under different oxygen partial pressures, after the liquid silver oxygen-generating system reaches equilibrium, a concentration gradient of silver to oxygen is formed between the dissolved oxygen liquid surface and the oxygen-generating chamber surface, where S1 is greater than S2. This causes oxygen in the dissolved oxygen liquid surface to diffuse towards the oxygen-generating chamber side and precipitate, thus producing high-purity oxygen.

[0009] Therefore, based on the physical properties of liquid silver selectively dissolving oxygen from the air and releasing it under reduced pressure, a complete theoretical scheme for oxygen production was established, consisting of three steps: oxygen dissolution, migration, and oxygen release. Based on this theoretical scheme, a liquid silver oxygen production device and method were designed. Summary of the Invention

[0010] The purpose of this invention is to address the shortcomings of existing technologies by proposing a liquid silver oxygen production device and method.

[0011] To achieve the above objectives, the present invention adopts the following technical solution: a liquid silver oxygen production device, comprising a dual-chamber furnace, a heating component, a vacuum suction mechanism, a water cooling mechanism, and a stirring mechanism;

[0012] The dual-chamber furnace has a racetrack-shaped cylindrical structure, including a furnace shell and a dual-chamber crucible disposed inside the furnace shell. The dual-chamber crucible is divided into an oxygen-generating chamber and an oxygen-dissolving chamber, with an opening between the two chambers to allow them to communicate. A furnace cover is provided on the top of the furnace shell, and the surface of the furnace cover has a feeding port, a stirring port, and a vacuum suction port. The feeding port is the opening of the oxygen-dissolving chamber. The stirring port and the vacuum suction port are located above the oxygen-generating chamber. The stirring mechanism is installed at the stirring port. The suction end of the vacuum suction mechanism is connected to an air cooler, which is connected to the vacuum suction port through a hot exhaust pipe. The exhaust end of the vacuum suction mechanism is connected to an oxygen storage tank. The heating component is located between the furnace shell and the dual-chamber crucible. A lifting mechanism is provided on one side of the dual-chamber furnace, and the lifting mechanism is connected to the stirring mechanism. The water cooling mechanism is sequentially connected to the dual-chamber furnace, the heating component, the stirring mechanism, and the air cooler for circulating water cooling.

[0013] Furthermore, the double-chamber crucible is made of graphite material, and an asbestos board insulation layer surrounds the outside of the double-chamber crucible.

[0014] Furthermore, the furnace shell and furnace cover adopt a double-layer stainless steel structure, with the outer layer made of ordinary steel plate and the inner layer made of stainless steel plate, and water circulating in the middle for cooling.

[0015] Furthermore, the heating component is a three-dimensional induction coil, which is a multi-turn coil spirally wound around the outside of the crucible.

[0016] Furthermore, the material of the three-dimensional induction coil is a square copper tube, which is cooled by water.

[0017] Furthermore, the air cooler is provided with a high-temperature oxygen inlet and a low-temperature oxygen outlet on both sides, and a hot water outlet and a cooling water inlet at the top and bottom of the air cooler, respectively.

[0018] Furthermore, the vacuum suction mechanism includes a water ring vacuum pump and a valve. The water ring vacuum pump is connected to the low-temperature oxygen outlet of the gas cooler via the valve, and the high-temperature oxygen inlet is connected to a hot exhaust pipe, which has an inverted U-shaped structure.

[0019] Furthermore, the stirring mechanism includes a drive motor, the drive end of which is connected to a cycloidal pinwheel reducer, a stirrer bracket is installed at the bottom of the cycloidal pinwheel reducer, a stirring rod is connected to the shaft of the cycloidal pinwheel reducer, a stirring blade is fixed at the bottom end of the stirring rod, a cooling water jacket is fitted on the outer surface of the stirring rod, and the cooling water jacket is connected to the top of the stirrer bracket.

[0020] The lifting mechanism is a lifting cylinder, and the telescopic end of the lifting cylinder is connected to the stirrer bracket.

[0021] Furthermore, the water cooling mechanism includes a closed counter-flow cooling tower and an auxiliary water tank. The surface of the closed counter-flow cooling tower is provided with a hot water inlet and a cooling water outlet. The cooling water outlet is connected to the auxiliary water tank, and a circulating water pump is connected to the bottom of the auxiliary water tank.

[0022] A method for producing oxygen from liquid silver, the specific steps of which are as follows:

[0023] Step 1: Place the metallic silver in the dissolved oxygen chamber and heat it using a heating element until the temperature of the metallic silver rises to its melting point. Oxygen from the atmospheric environment dissolves into the liquid silver in the dissolved oxygen chamber.

[0024] Step 2: Start the stirring mechanism to stir the liquid silver, so that the liquid silver circulates in the dissolved oxygen chamber and the oxygen generation chamber;

[0025] Step 3: When liquid silver flows from the dissolved oxygen chamber into the oxygen generating chamber, oxygen diffuses into the oxygen generating chamber. After the opening between the oxygen generating chamber and the dissolved oxygen chamber is submerged, the vacuum suction mechanism is activated to create a negative pressure environment in the oxygen generating chamber.

[0026] Step 4: The high-temperature oxygen in the oxygen generating chamber is introduced into the air cooler through the hot exhaust pipe to cool it down, and then collected using the oxygen storage tank.

[0027] The beneficial effects of this invention are:

[0028] 1. This invention utilizes the physical property of liquid silver to selectively dissolve oxygen in the air and release it under pressure to produce high-purity oxygen. The oxygen generation chamber and the oxygen dissolving chamber are separated but connected by liquid silver. A vacuum mechanism is used to release the oxygen dissolved in the liquid silver under pressure.

[0029] 2. The present invention has high oxygen production efficiency. It adopts a stirring mechanism to guide the liquid silver to circulate in a directional manner between the oxygen dissolution chamber and the oxygen production chamber, forming a working state of dissolving oxygen and producing oxygen at the same time, which accelerates the collection of oxygen in the oxygen production chamber.

[0030] 3. The oxygen production process of this invention is mechanically automated, automatically controlling heating, melting, stirring, and air intake mechanisms to achieve automatic adjustment, circulation, and efficient oxygen production.

[0031] 4. This invention can ensure the stability of furnace temperature during the oxygen production process, reduce energy loss, and is environmentally friendly.

[0032] In summary, the liquid silver oxygen production device and method are based on the principle that one end of the oxygen production device is in contact with the air environment to dissolve oxygen, while the other end releases and collects oxygen when the vacuum system depressurizes, forming a working state of simultaneous air intake and degassing, thereby achieving the purpose of oxygen production. By using a racetrack (waist) shaped double-chamber furnace, one chamber dissolves oxygen and the other produces oxygen. Combined with related technologies such as metal melting, vacuum degassing and oxygen production processes, the temperature of silver remains constant during the dissolution and release of oxygen, thus better realizing cyclic oxygen production.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] like Figures 1-5 As shown, a liquid silver oxygen production device includes a dual-chamber furnace 1, a heating component 8, a vacuum suction mechanism 6, a water cooling mechanism 5, and a stirring mechanism 2.

[0045] The double-chamber furnace 1 has a racetrack-shaped cylindrical structure, including a furnace shell and a double-chamber crucible inside the furnace shell. The double-chamber crucible is divided into an oxygen-generating chamber 13 and an oxygen-dissolving chamber 12. An opening is made between the oxygen-generating chamber 13 and the oxygen-dissolving chamber 12 to connect the two chambers. A furnace cover 11 is provided on the top of the furnace shell. The surface of the furnace cover 11 has a feeding port, a stirring port, and a vacuum suction port. The feeding port is the opening of the oxygen-dissolving chamber 12. The stirring port and the vacuum suction port are located above the oxygen-generating chamber 13. The stirring mechanism 2 is installed at the stirring port. The suction end of the vacuum suction mechanism 6 is connected to the air cooler 4. The air cooler 4 is connected to the vacuum suction port through a hot exhaust pipe 9. The exhaust end of the vacuum suction mechanism 6 is connected to an oxygen storage tank 7. The heating component 8 is located between the furnace shell and the double-chamber crucible. A lifting mechanism 3 is provided on one side of the double-chamber furnace 1. The lifting mechanism 3 is connected to the stirring mechanism 2. The water cooling mechanism 5 is connected to the double-chamber furnace 1, the heating component 8, the stirring mechanism 2, and the air cooler 4 in sequence for circulating water cooling.

[0046] The double-chamber crucible is made of graphite, which prevents carbon and silver from reacting, reducing silver leakage and avoiding contamination of the molten silver by other refractory materials. Furthermore, the double-chamber crucible is surrounded by an asbestos insulation layer, ensuring long-term furnace operation at high temperatures and extending its service life.

[0047] The furnace shell must have the ability to resist oxidation, corrosion and high temperature. Therefore, the furnace shell and furnace cover 11 adopt a double-layer stainless steel structure. The outer layer is made of ordinary steel plate and the inner layer is made of stainless steel plate. Water is circulated in the middle for cooling, which is convenient to connect with the water cooling mechanism 5 for cooling. The inner wall of the furnace cover is finely polished to facilitate the removal of dirt and splashes in the metallic silver during smelting.

[0048] like Figure 2As shown, the heating component 8 is a three-dimensional induction coil. The three-dimensional induction coil is a multi-turn coil spirally wound around the outside of the crucible, which can keep the temperature inside the crucible uniform at all times. It has a large inductance value and a small size, which can improve the efficiency of electromagnetic induction heating. According to the skin effect of electromagnetic field and the ring effect of current, the current region of rectangular tube is closer to the heating element than that of circular tube. Moreover, the cooling performance of circular tube is poor and the leakage of magnetic field is serious. Therefore, the cross-section of the induction coil is designed to be rectangular. The material of the three-dimensional induction coil is a square copper tube. Water is circulated inside the tube for cooling. The lower end is the cooling water inlet and the upper end is the cooling water outlet, which facilitates connection with the water cooling mechanism 5 for cooling.

[0049] like Figure 1 and Figure 5 As shown, the air cooler 4 has a high-temperature oxygen inlet 41 and a low-temperature oxygen outlet 42 on both sides, and a hot water outlet 44 and a cooling water inlet 43 at the top and bottom of the air cooler 4, respectively. The vacuum suction mechanism 6 includes a water ring vacuum pump 61 and a valve 62. The water ring vacuum pump 61 is connected to the low-temperature oxygen outlet 42 of the air cooler 4 through the valve 62. The high-temperature oxygen inlet 41 is connected to the hot exhaust pipe 9, which has an inverted U-shaped structure.

[0050] The melting temperature of metallic silver is typically very high, so the oxygen discharged from the oxygen-generating chamber is a high-temperature gas and cannot be directly collected. Therefore, an air cooler 4 is installed to cool the high-temperature oxygen. The inverted U-shaped hot exhaust pipe 9 forms a heat insulator, which can separate the high-density cold gas near the air cooler 4 from the high-temperature oxygen in the upper part of the oxygen-generating chamber 13. Therefore, the upper part of the oxygen-generating chamber 13 can easily maintain a high operating temperature, thereby preventing the furnace body from crusting and improving the degassing efficiency.

[0051] Once the metallic silver is completely melted and the central opening is submerged, the water ring vacuum pump 61 is activated to evacuate the oxygen-generating chamber 13 into a vacuum. This creates a pressure difference between the oxygen-generating chamber 13 and the dissolved oxygen chamber 12, separating them. The liquid silver in the oxygen-generating chamber rises to a height equal to the pressure difference. Through the stirring mechanism 2, the liquid silver undergoes a certain degree of circulation. Without changing the temperature, the vacuum suction mechanism 6 in the dual-chamber furnace 1 reduces the solubility of oxygen in the liquid silver, causing oxygen to migrate and diffuse to the surface of the liquid silver, where it is then extracted and collected. The operation of the vacuum suction mechanism 6 is controlled by a programmable controller, allowing for both manual and automatic operation. The valve 62 has a long service life.

[0052] The water ring vacuum pump 61 draws gas into the oxygen generation chamber 13. Its operating characteristic is constant volume; regardless of the gas pressure, the volume of gas removed per unit time remains constant. It is simple to install, oil-free, and safe and reliable. The suction pressure can reach 33 mbar absolute pressure (97% vacuum), and the ultimate vacuum is 2000–4000 Pa. The working principle of the water ring vacuum pump is as follows:

[0053] The pump body has eccentric blades inside. When working, the water in the pump forms a water ring against the side wall of the pump under the action of centrifugal force. A sealed space is formed between the blades and the water ring. When the space expands, air is drawn in; when the space shrinks, air is expelled. The gas enters from the suction port and exits from the exhaust port. Every time the blade rotates once, the space between the blade and the water ring will draw in and expel air once. With many spaces working continuously, gas can be continuously drawn in or transported.

[0054] like Figure 4 As shown, the stirring mechanism 2 includes a drive motor 21, the drive end of the drive motor 21 is connected to a cycloidal pinwheel reducer 22, the bottom of the cycloidal pinwheel reducer 22 is equipped with a stirrer bracket 23, the shaft of the cycloidal pinwheel reducer 22 is connected to a stirring rod, the bottom end of the stirring rod is fixed with stirring blades 25, the outer surface of the stirring rod is fitted with a cooling water jacket 24 to facilitate connection with the water cooling mechanism 5 for cooling, the cooling water jacket 24 is connected to the top of the stirrer bracket 23, and the lifting mechanism 3 is a lifting cylinder, the extension end of the lifting cylinder is connected to the stirrer bracket 23.

[0055] The stirring mechanism 2 operates in a circular motion. As the blades rotate, the blades at different angles and positions pass over the liquid silver, primarily experiencing the reaction force, friction, and centrifugal force exerted by the liquid silver on the stirring blades. This guides the liquid silver to produce circumferential (tangential), radial, and vertical movements, thus generating a stirring effect. However, if the stirring rate is too high, the oxygen production efficiency will actually decrease. This is because at high speeds, the centrifugal force of the liquid silver is greater than the frictional force between it and the blades. The rapid circulation of liquid silver from the dissolved oxygen chamber to the oxygen production chamber and back again results in low oxygen release and dissolution efficiency. Therefore, during operation, the centrifugal force of the liquid silver in the stirring mechanism 2 should not exceed the frictional force between it and the stirring blades.

[0056] The density of liquid silver is ρ = 9.33 g·cm³. -3 The viscosity at the melting point is μ = 4.21 mPa·s. A six-bladed disc turbine agitator is selected. The agitator and agitator shaft need to be immersed in high-temperature liquid silver. Both materials are made of 304 stainless steel, which has advantages such as high strength, corrosion resistance, and good high-temperature mechanical properties. A three-phase asynchronous motor is selected for drive, and the cycloidal pinwheel reducer 22 has high transmission efficiency, smaller size and weight than ordinary gear reducers of the same power, and longer service life. The agitator support 23 is made of cast iron, which has high strength and durability.

[0057] like Figure 5As shown, the water cooling system 5 includes a closed-loop counter-flow cooling tower 51 and an auxiliary water tank 53. The surface of the closed-loop counter-flow cooling tower 51 is provided with a hot water inlet 52 and a cooling water outlet 55. The cooling water outlet 55 is connected to the auxiliary water tank 53, and a circulating water pump 54 is connected to the bottom of the auxiliary water tank 53. Circulating water enters the heat source to be cooled through the auxiliary water tank 53, undergoes heat exchange and temperature rise, and then enters the closed-loop counter-flow cooling tower 51 from the hot water inlet 52 for cooling. It flows out from the cooling water outlet 55 and is then sent to the heat source by the circulating water pump 54. This closed-loop cooling system enables water recycling, prevents evaporation and eliminates impurities, isolates the system from the outside environment, and does not pollute the environment.

[0058] The reasons why each component needs to be cooled are as follows:

[0059] Dual-chamber furnace 1 cooling. The furnace body (furnace shell and furnace cover 11) adopts a double-layer structure and is cooled by water circulation to ensure that the furnace body can operate stably and safely under permissible environmental and temperature conditions.

[0060] Induction coil cooling. The coil is designed with a hollow structure and internal water cooling. This dissipates heat from the induction coil and reduces the resistance of the copper coil. Copper has a temperature coefficient of resistance of 0.004 ppm / ℃, and its resistance loss decreases by 4% for every 10℃ decrease in operating temperature.

[0061] The stirring mechanism 2 is used for cooling. Located above the furnace cover 11 of the dissolved oxygen chamber, the stirring mechanism 2's blades are in direct contact with the liquid silver. High temperatures can be transmitted through the stirring shaft to the stirring drive motor 21 and the cycloidal pinwheel reducer 22, causing damage and malfunction, thus reducing production efficiency. Therefore, a hollow cooling water jacket 24 is installed on the stirring shaft, connected to the water cooling mechanism 5, to circulate cooling for the stirring mechanism 2 and prevent damage to the stirring drive motor 21 and the cycloidal pinwheel reducer 22.

[0062] Oxygen cooling. The oxygen exiting the oxygen-generating chamber 13 is at a very high temperature and cannot be collected directly; it needs to be cooled. The air cooler 4 transfers the heat carried by the oxygen to the cooling water, ensuring that the oxygen from the oxygen-generating chamber 13 is cooled to the required temperature range. During operation, cooling water enters the air cooler 4 through the liquid channel inlet at the bottom, while the high-temperature oxygen enters through the gas channel inlet at the top. The high-temperature oxygen and cooling water form a counter-current heat exchange. After heat exchange, the low-temperature oxygen is discharged from the lower gas outlet and collected, while the hot water enters the closed-loop counter-current cooling tower 51 through the upper liquid channel outlet for cooling, forming cooling water that then re-enters the air cooler 4 for heat exchange, creating a cycle. The system operates without blockage or leakage, possesses properties such as high temperature resistance, corrosion resistance, and resistance to extreme cold and heat, and features high heat exchange efficiency and a long service life.

[0063] Example 2:

[0064] A method for producing oxygen from liquid silver, the specific steps of which are as follows:

[0065] Step 1: Place metallic silver in the oxygen dissolving chamber 12 and heat it using the heating component 8 until the temperature of the metallic silver rises to its melting point. Oxygen dissolves from the atmospheric environment into the liquid silver in the oxygen dissolving chamber 12. The heating and melting method is the key to producing oxygen from metallic silver. Because silver has high thermal conductivity, when the temperature of silver is raised to its melting point, a solid-liquid phase transformation can occur rapidly. The vacuum system is activated, and a negative pressure environment is formed in the oxygen production chamber. In order to maintain the dynamic balance of oxygen production, the temperature needs to be stably controlled near the melting point of silver. Therefore, electromagnetic induction heating is adopted.

[0066] Step 2: Activate the stirring mechanism 2 to stir the liquid silver, causing it to circulate within the dissolved oxygen chamber 12 and the oxygen generating chamber 13. The stirring mechanism 2 guides the liquid silver from the dissolved oxygen chamber 12 through one hole in the partition into the oxygen generating chamber 13, and then introduces the deoxygenated liquid silver from the oxygen generating chamber 13 back into the dissolved oxygen chamber 12 through the other hole in the partition. Since the oxygen content in the liquid silver is unsaturated, it has a high absorption capacity for oxygen in the air, absorbing oxygen to achieve gas balance. This creates an infinite cycle of dissolved and released oxygen, achieving the purpose of oxygen generation from metallic silver.

[0067] Step 3: When liquid silver flows from the dissolved oxygen chamber 12 into the oxygen generating chamber 13, oxygen diffuses into the oxygen generating chamber 13. After the opening between the oxygen generating chamber 13 and the dissolved oxygen chamber 12 is submerged, the vacuum suction mechanism 6 is activated, creating a negative pressure environment inside the oxygen generating chamber 13. The oxygen generating chamber 13 and the dissolved oxygen chamber 12 are separated by liquid silver, creating an internal and external pressure difference. The liquid silver in the oxygen generating chamber 13 will rise to a height equal to the pressure difference. Through the action of the stirring mechanism 2, the liquid silver will generate a certain amount of circulation.

[0068] Step 4: The high-temperature oxygen in the oxygen generating chamber is introduced into the air cooler 4 through the hot exhaust pipe 9 to cool down, and then collected using the oxygen storage tank 7.
