Description

Technical Field

[0001] The invention relates to the technical field of hydrogen production equipment, and in particular to a novel chemical chain hydrogen generator. Background Art

[0002] As the ultimate energy source, hydrogen energy has the characteristics of being renewable, zero-emission, high calorific value, storable, and widely used. It is generally believed that hydrogen can become a green energy that can replace fossil energy in the future. As a strategic emerging industry, the hydrogen energy industry chain is relatively long, including hydrogen production, storage, transportation, hydrogenation, use and many other links. Each link has its own product development direction, and they are closely linked. There is great potential for each link in the industry chain.

[0003] There are many different hydrogen production pathways, but the costs of hydrogen production vary greatly due to different raw material prices. The most commonly used hydrogen production method is water electrolysis. The water electrolysis process is not complicated, but it consumes too much electricity. The cost of large-scale hydrogen production is much higher than that of hydrogen production from coal and natural gas. Therefore, this hydrogen production method has no competitive advantage. The chemical process of metal-water reaction to produce hydrogen is a green hydrogen production process, but there are many problems with the reaction of a single metal with water. Although some single metals have high reactivity, an oxide film will form on the surface during the reaction, which hinders the continued reaction of the metal with water. Therefore, the current metal-water reaction hydrogen production equipment mainly changes the shape of the metal, such as making aluminum into aluminum boxes, aluminum powder, sheets, etc., to increase the contact surface area and improve the conversion rate.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of the embodiments of the present invention based on its overall structure.

[0045] like Figure 1-8 As shown, the present invention discloses a novel chemical chain hydrogen generator, comprising a reaction vessel 1, a lower rotating mechanism 2, an upper rotating mechanism 3, a feeding mechanism 4 and a steam generator 5, wherein the reaction vessel 1 comprises a discharge port 11 and a gas outlet 12, the lower rotating mechanism 2 comprises a lower turntable 21 and an annular protrusion 22, the lower turntable 21 is horizontally rotatable in the reaction vessel 1, a plurality of annular protrusions 22 of different diameters are concentrically and spaced apart on the upper surface of the lower turntable 21, the upper rotating mechanism 3 comprises an upper turntable 31 and an annular net cylinder 32, the upper turntable The disc 31 and the lower turntable 21 are close to each other and are arranged with a common rotation axis. A plurality of annular mesh cylinders 32 of different diameters are concentrically and spacedly arranged on the lower surface of the upper turntable 31. The annular mesh cylinders 32 and the annular protrusions 22 are staggered with each other and a gap is left. The feeding port 41 of the feeding mechanism 4 is connected with the upper rotating mechanism 3, and the metal powder filled inside enters the lower turntable 21 through the upper rotating mechanism 3. The air delivery port 51 of the steam generator 5 is connected with the lower rotating mechanism 2, and the high-temperature water vapor generated inside enters the upper turntable 31 through the lower rotating mechanism 2. The metal powder in this embodiment moves from the inside to the outside under the centrifugal force of the lower turntable 21 and the high-temperature water vapor. Under the staggered blocking effect of the annular mesh cylinders 32 and the annular protrusions 22, the reaction time of the metal powder and the high-temperature water vapor can be prolonged; under the joint action of the lower rotating mechanism 2 and the upper rotating mechanism 3, the metal powder is kept in a discrete flying state, which can increase the contact area between the high-temperature water vapor and the metal powder and improve the conversion efficiency. In addition, the metal powder will collide with the high-speed rotating annular mesh cylinder 32 and the annular protrusion 22 under the action of centrifugal force, which will destroy the oxide film on the surface of the metal powder and further improve the utilization rate of the metal powder.

[0046] It is worth noting that the metal powder used in this embodiment is one of aluminum powder, magnesium powder, aluminum-magnesium alloy powder, and aluminum-magnesium-lithium alloy powder; when the temperature is below 350°C, aluminum reacts with water vapor to generate hydrogen and aluminum hydroxide. When the temperature is higher than 350°C, aluminum hydroxide will further decompose into aluminum oxide. When the temperature is higher than 800°C, the reaction rate of aluminum and water vapor is the fastest. The water vapor can be heated to a higher temperature by increasing the pressure and secondary heating, but the corresponding equipment cost and energy consumption will also increase. Usually, the water vapor temperature in the boiler can be maintained at about 370°C. Therefore, the steam generator 5 in this embodiment is used to convert water into high-temperature water vapor above 350°C.

[0047] Continue to refer Figure 5 The reaction vessel 1 is mounted on the fixing frame 8 by means of a bolt assembly, a detachable cover 13 is provided on the top thereof, and two symmetrical funnel-shaped discharge ports 11 are provided on the bottom thereof, so as to facilitate the collection of the metal powder; an air outlet 12 is provided on the cover 13, and the metal powder in the reaction vessel 1 can generate hydrogen after chemical reaction with high-temperature water vapor, and the mixed gas in the reaction vessel 1 enters into external processing equipment such as a condenser and a gas-liquid separator through the air outlet 12 and a pipeline, so as to facilitate the purification and storage of the hydrogen.

[0048] Continue to refer Figure 6 The lower rotating mechanism 2 in this embodiment also includes a first hollow rotating shaft 23, a first driving mechanism 24 and fins 25. The upper end of the first hollow rotating shaft 23 passes through the upper surface of the lower turntable 21, and the lower end passes through the bottom of the reaction container 1 and is connected to the air supply port 51. The first driving mechanism 24 is used to drive the first hollow rotating shaft 23 and the lower turntable 21 to rotate horizontally. The outer side surfaces of the plurality of annular protrusions 22 are provided with vertical fins 25, which can increase the force on the upward and outward movement of the metal powder during rotation. Specifically, the cross section of the annular protrusion 22 is set to be a trapezoid with a narrow upper part and a wide lower part, and the heights of two adjacent annular protrusions 22 are different. In this embodiment, four annular protrusions 22 are provided, including three different heights of high, medium and low, and the height sequence from the inside to the outside is medium, low, high and low; a pulley is installed at the lower part of the first hollow rotating shaft 23, and the motor of the first driving mechanism 24 drives the first hollow rotating shaft 23 to rotate through the pulley assembly.

[0049] Continue to refer Figure 7-8The upper rotating mechanism 3 in this embodiment further includes a second hollow rotating shaft 33 and a second driving mechanism 34. The lower end of the second hollow rotating shaft 33 passes through the lower surface of the upper rotating disk 31, and the upper end passes through the top of the reaction container 1 and is connected to the feeding port 41. The second driving mechanism 34 is used to drive the second hollow rotating shaft 33 and the upper rotating disk 31 to rotate horizontally. The upper rotating disk 31 rotates in opposite directions to the lower rotating disk 21. Specifically, the upper end of the second hollow rotating shaft 33 passes through the middle of the cover body 13, and a gear is installed on the upper part of the second hollow rotating shaft 33. The motor of the second driving mechanism 34 drives the second hollow rotating shaft 33 to rotate through a gear set.

[0050] Preferably, the surfaces of the lower turntable 21, the annular protrusion 22, the upper turntable 31 and the annular mesh cylinder 32 are all set to be rough frosted surfaces, which can more effectively destroy the oxide film on the surface of the metal powder.

[0051] Preferably, rotating sealing rings are respectively provided at the connection between the first hollow rotating shaft 23 and the reaction container 1 and the air supply port 51, and rotating sealing rings are respectively provided at the connection between the second hollow rotating shaft 33 and the cover body 13 and the feed port 41, which can improve the air tightness of the reaction container 1 and the stability of the rotor.

[0052] Continue to refer Figure 3-4 The feeding mechanism 4 in this embodiment includes a storage bin 42, a first feeding screw 43 and a first driving motor 44.

The top of the storage bin 42 is provided with a hinged bin door 421, which is convenient for adding metal powder to the storage bin 42 in time. It is worth noting that the rotation direction of the first feeding screw 43 when conveying metal powder downward is opposite to the rotation direction of the second hollow rotating shaft 33, which can improve the conveying efficiency of the metal powder.

[0053] Furthermore, the feeding mechanism 4 also includes a spindle-shaped guide member 45. The lower end of the first feeding screw 43 passes through the second hollow rotating shaft 33 and is connected to the upper end of the guide member 45. The lower end of the guide member 45 is arranged directly above the upper end of the first hollow rotating shaft 23. The first hollow rotating shaft 23 and the second hollow rotating shaft 33 are arranged with a corotating axis. The middle diameter of the guide member 45 is larger than the diameters of the first hollow rotating shaft 23 and the second hollow rotating shaft 33, which can prevent the high-temperature water vapor passing through the first hollow rotating shaft 23 from directly hitting the second hollow rotating shaft 33.

[0054] Continue to refer Figure 2, this embodiment also includes a material distribution mechanism 6 and a recovery box 7, the inlet of the material distribution mechanism 6 is connected with the discharge port 11, the first outlet is connected with the air supply port 51, and the second outlet is connected with the recovery box 7, and the material distribution mechanism 6 is used to distribute the metal powder in the discharge port 11 to the first outlet or the second outlet. Specifically, the two discharge ports 11 are respectively connected with the two ports of the three-way piece 111, and the third port of the three-way piece 111 is connected with the inlet of the material distribution mechanism 6. Further, the material distribution mechanism 6 includes a tube body 61, a second feeding screw 62 and a second driving motor 63, the tube body 61 is sleeved on the second feeding screw 62, and one end of the second feeding screw 62 is connected to the output end of the second driving motor 63; the first outlet and the second outlet of the material distribution mechanism 6 are arranged at the two ends of the tube body 61 away from each other, and the inlet is arranged on the tube body 61 between the first outlet and the second outlet.

[0055] Specifically, the steam generator 5 includes a mixing chamber 52, the bottom of the mixing chamber 52 is connected to the air delivery port 51, and the top is connected to the lower end of the first hollow rotating shaft 23. The second drive motor 63 is installed on the fixed frame 8, and the output end is sealed and rotatably connected to the first end of the tube body 61, and is fixedly connected to one end of the second feeding screw 62.

The inlet of the dividing mechanism 6 is arranged above the middle of the tube body 61, and the second end of the tube body 61 is arranged as the first outlet of the dividing mechanism 6. The second outlet of the dividing mechanism 6 is arranged below the first end of the tube body 61, and a pressure relief valve 71 is arranged on the recovery box 7.

[0056] It can be understood that the first drive mechanism 24, the second drive mechanism 34, the first drive motor 44 and the second drive motor 63 in this embodiment are electrically connected to the control system respectively. When the second drive motor 63 is set to rotate forward, the metal powder in the discharge port 11 is transported to the first outlet by the second feeding screw 62, mixed with high-temperature water vapor in the mixing chamber 52 and then re-sent into the reaction container 1, thereby achieving precise control of the reaction time of the metal powder and the high-temperature water vapor, and further improving the conversion efficiency; when the second drive motor 63 is set to rotate reversely, the metal powder in the discharge port 11 is transported to the second outlet by the second feeding screw 62 and then enters the recovery box 7. In addition, the control system performs programmatic control of the working state of the drive mechanism and the drive motor, which can simplify the operation steps and improve work efficiency.

[0057] In summary, a new type of chemical chain hydrogen generator in this embodiment enables the metal powder to move from the inside to the outside under the centrifugal force of the lower turntable 21 and the action of high-temperature water vapor. Under the staggered blocking action of the annular mesh tube 32 and the annular protrusion 22, the reaction time of the metal powder and the high-temperature water vapor can be extended; under the joint action of the lower rotating mechanism 2 and the upper rotating mechanism 3, the metal powder is kept in a discrete flying state, which can increase the contact area between the high-temperature water vapor and the metal powder and improve the conversion efficiency; the metal powder will also collide with the high-speed rotating annular mesh tube 32 and the annular protrusion 22 under the action of centrifugal force, which plays a role in destroying the oxide film on the surface of the metal powder, thereby improving the utilization rate of the metal powder; by controlling the second drive motor 63 to rotate forward or reverse, the metal powder in the discharge port 11 can be distributed to the first outlet or the second outlet, and the reaction time of the metal powder and the high-temperature water vapor can be controlled, further improving the conversion efficiency.
