Description

Technical Field

[0001] This utility model relates to the field of formic acid hydrogen production technology, specifically a power generation device based on formic acid catalytic hydrogen production. Background Technology

[0002] Many methods for producing and storing hydrogen have been developed, but they all face significant technical obstacles. For example, methanol reforming for hydrogen production generally requires temperatures above 200 degrees Celsius, and the resulting hydrogen contains a high concentration of CO. CO can easily poison fuel cells, necessitating a subsequent purification process. Therefore, methanol-to-hydrogen production is very complex and inefficient, making new hydrogen production methods highly valuable.

[0003] In the current formic acid catalytic hydrogen production process, the generated hydrogen is directly discharged from inside the reactor. This practice may lead to frequent fluctuations in the hydrogen concentration inside the reactor, thereby increasing safety risks. In addition, frequent discharge may also exacerbate the wear and tear on discharge pipelines and equipment, which may further increase safety hazards.

[0004] Therefore, this invention provides a power generation device based on formic acid catalytic hydrogen production to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This invention provides a power generation device based on formic acid catalytic hydrogen production, such as... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the formic acid catalytic hydrogen production power generation device includes a base plate 1, a support frame 2 fixedly installed on the base plate 1, a fuel cell 4, a reaction vessel 3 fixedly installed on the support frame 2, a gas buffer tank 5 fixedly installed on the fuel cell 4, an exhaust pipe 6 fixedly installed on the reaction vessel 3, and a metering mechanism for metering hydrogen gas exhaust inside the exhaust pipe 6.

[0027] The metering mechanism includes a fixed plate 7 fixedly installed inside the discharge pipe 6, a guide rod 8 fixedly installed between the two fixed plates 7, a blocking plate 9 slidably installed on the guide rod 8, a tension spring 10 sleeved on the guide rod 8, a rotating plate 11 rotatably installed inside the discharge pipe 6, an inclined groove 12 opened inside the discharge pipe 6, an air bladder 13 set inside the inclined groove 12, a heat-resistant gas pipe 14 fixedly installed on the side surface of the reactor 3, an insert 15 fixedly installed on the blocking plate 9, and a slot 16 opened inside the rotating plate 11 for the insert 15 to be inserted.

[0028] The guide rod 8 passes through the rotating plate 11, one end of the tension spring 10 is fixedly connected to one side of one of the fixed plates 7, and the other end of the tension spring 10 is fixedly connected to one side of the blocking plate 9.

[0029] The end of the heat-resistant gas pipe 14 away from the reactor 3 passes through the discharge pipe 6 and is fixedly connected to one side of the gas bag 13. One side of the gas bag 13 is in contact with the side surface of the rotating plate 11.

[0030] In operation, the formic acid catalytic hydrogen production power generation device first places the base plate 1 in a suitable position. Then, formic acid feedstock and catalyst are added into the reactor 3 through the feed pipe at the top of the reactor 3. After adding the formic acid feedstock and catalyst, the heating system of the reactor 3 is started, causing the formic acid to decompose and produce hydrogen under the action of the catalyst. The generated hydrogen gas enters the discharge pipe 6 through the outlet inside the reactor 3. At this time, due to the elastic force of the tension spring 10, the blocking plate 9 will tightly adhere to the inner wall of the discharge pipe 6 to prevent the hydrogen gas from being directly discharged. The hydrogen gas pushes the blocking plate 9 along the guide rod 8 until the insert 15 is attached to one side of the rotating plate 11. When the hydrogen gas accumulates to a certain level, the gasbag 13 expands due to the compression of a portion of the hydrogen gas transmitted by the heat-resistant gas pipe 14, pushing the rotating plate 11 to rotate inside the inclined groove 12 in the discharge pipe 6. The rotation of the rotating plate 11 aligns the slot 16 with the insert 15, and the insert 15 is inserted into the slot 16. At this time, the hydrogen gas is discharged from the discharge pipe 6 and enters the gas buffer tank 5 for buffering and storage. Then, it is used to generate electricity through the fuel cell 4.

[0031] In order to ensure that the formic acid raw material and the catalyst are fully mixed, such as Figure 1 , Figure 2 and Figure 6 As shown, the reactor 3 is rotatably connected to a rotating shaft 18, and a stirring blade 19 is fixedly connected to the side surface of the rotating shaft 18. Multiple stirring blades 19 are provided and are evenly distributed on the rotating shaft 18.

[0032] When the formic acid catalytic hydrogen production power generation device is in use, after the formic acid raw material and catalyst are added into the reactor 3, the rotating shaft 18 rotates inside the reactor 3, thereby driving the stirring blade 19 to mix and stir the formic acid raw material and catalyst, ensuring that they can react fully and improve the hydrogen production efficiency.

[0033] It should be noted that, in order to drive both rotating shafts 18 to rotate simultaneously, such as Figure 1 , Figure 2 and Figure 6 As shown, a fixed base 17 is fixedly connected to the top of the reactor 3, and a synchronous wheel 20 is rotatably connected inside the fixed base 17. The top end of the rotating shaft 18 passes through the reactor 3 and the fixed base 17 in sequence, and the top end of the rotating shaft 18 is fixedly connected to the bottom of the synchronous wheel 20.

[0034] A timing belt 21 is movably connected between the two timing pulleys 20. A motor 22 is fixedly connected to the top of the fixed base 17. The output end of the motor 22 passes through the fixed base 17 and is fixedly connected to the top of one of the timing pulleys 20.

[0035] When the formic acid catalytic hydrogen production power generation device is in use, after the motor 22 is started, its output end will drive the synchronous wheel 20 fixedly connected to it to rotate. Since the two synchronous wheels 20 are movably connected by the synchronous belt 21, when one synchronous wheel 20 rotates, it will drive the other synchronous wheel 20 to rotate synchronously through the synchronous belt 21. In this way, the two rotating shafts 18 will be driven at the same time, and then rotate inside the reactor 3, driving the stirring blades 19 to mix and stir the formic acid raw material and the catalyst. This design not only improves the stirring efficiency, but also ensures the full mixing of the formic acid raw material and the catalyst.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
