Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen production equipment, and in particular relates to a portable chemical hydrogen production machine. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. It requires a hydrogen supply system to provide a stable and reliable supply of hydrogen for its power generation. Currently, there are several hydrogen use schemes to address the difficulties in using hydrogen for fuel cells in the wild. Among them, chemical hydrogen production based mainly on borohydride hydrolysis has attracted widespread attention due to its advantages such as high hydrogen purity, low additional power consumption, and unlimited endurance. However, in order to apply chemical hydrogen production to the wild environment, portable hydrogen production equipment is needed to produce hydrogen in real time on site.

[0003] Existing portable hydrogen production equipment cannot be well applied to field fuel cell hydrogen supply. For example, the portable, safe and controllable hydrolysis hydrogen production device disclosed in CN102167285A is a relatively common chemical hydrogen production equipment, including a reactor, a water storage tank and pipelines. A micro pump is provided between the reactor and the water storage tank. A water inlet and an air outlet are provided on the reactor. The air outlet is connected to a pressure sensor and a condenser dryer. The device has many pipelines and a large volume. It is not easy to carry and transfer. In addition, the interface may loosen and the pipeline may be squeezed during the transfer process, which will affect the hydrogen production process and pose a safety hazard.

[0004] CN208200367U discloses a portable hydrogen production and supply device, including a water storage container and a reaction container, the reaction container is placed in the water storage container, the reaction container is connected to a water pipe, the water stored in the water storage container is transported to the reaction container through the water pipe, the reaction container is provided with a first air outlet, and the water storage container is provided with a second air outlet. The device integrates the reaction container and the water storage container into an integrated design, greatly reduces the volume, and eliminates complicated pipelines, effectively improving portability, but the addition of raw materials is inconvenient, and the water storage container and the reaction container need to be disassembled, which is time-consuming and labor-intensive, and the hydrogen production effect is not good, and the hydrogen will carry a large amount of water vapor and cannot be used directly, and needs to be subsequently dried, which affects the efficiency.

[0017] The present invention has the following beneficial effects:

[0018] 1. By arranging the hydrogen production components in the casing and arranging a movable protective cover outside the casing, an integrated design is realized, which significantly reduces the size of the device, is convenient to carry and transfer, and the pipeline is also hidden, which improves safety; as long as the quick-plug female connector in the protective cover is connected to the male connector of the fuel tank, the hydrogen production pipeline can be connected. On the one hand, this structure plays a role in fixing the fuel tank, and on the other hand, it can also well protect the water inlet pipe and the air outlet pipe on the fuel tank, so that it is not deformed and blocked by accidental contact from the outside, and the replacement of the fuel tank is extremely convenient, saving time and effort; the generated hydrogen is separated and dried in the casing, and can be used directly after output, with good hydrogen production effect and high efficiency. Therefore, under the condition of sufficient raw materials, the present invention can ensure long-term hydrogen supply, meet the needs of corresponding field hydrogen equipment including fuel cells, and has good application prospects.

[0019] 2. By setting a locking piece on the quick-plug female head, the quick-plug female head and the quick-plug male head are clamped together to prevent the water inlet pipe and the air outlet pipe from being separated and ensure airtightness; at the same time, the setting of the locking piece will not affect the removal of the quick-plug female head. Just press the spring on the locking piece to release the quick-plug male head, which is convenient for operation. More optimized, by setting an annular groove on the quick-plug male head to engage with the locking piece, the tightness of the connection between the quick-plug female head and the quick-plug male head is further improved.

[0020] 3. By placing the fan directly opposite the fuel tank and providing a through-hole on the casing, the fan can not only dissipate heat to the internal components and environment of the casing, but also dissipate heat to the fuel tank outside the casing, ensuring that the reaction can maintain high efficiency; in a low-temperature environment, the heat of the fuel tank can be transferred to the casing through the through-hole to prevent the pipeline from freezing.

[0021] 4. By setting the water-dividing column and the drying column with upper and lower covers, and setting the lower cover outside the casing, it is convenient to replace the filter material and drain the water. The water-dividing pipe and the drying pipe can be designed to be integrated into one piece, so that they can be disassembled or replaced at the same time, which is more convenient to use.

[0022] 5. The hydrogen generator of the present invention can be adapted to a fuel cell power generation system, and the temperature control of the thermostat and the signal control of the drive pump are centralized in the power generation system control circuit board, thereby reducing the size and weight of the hydrogen generator and improving its lightness and portability.
