Description

Technical Field

[0001] The present invention relates to the field of chemistry, and in particular to a hydrogen preparation technology, and specifically to a highly efficient, environmentally friendly, hydrolysis hydrogen production system that can be used in a low-temperature environment. Background Art

[0002] It is a known technology that sodium borohydride can be hydrolyzed to produce hydrogen, especially under the action of transition metal catalysts, the speed of hydrolysis to produce hydrogen can be increased. Patent US 6932847B2 details a hydrogen generator device in which a sodium borohydride aqueous solution is pumped into a catalyst tube by a pump to produce hydrogen. After the hydrolysis hydrogen production reaction occurs in the catalyst tube, the byproduct sodium metaborate generated by the reaction needs to be quickly removed from the catalyst area to avoid preventing the reaction from continuing. Hydrogen is transmitted to the required components, such as a fuel cell, through a hydrogen pipeline.

[0003] However, in the above-mentioned patent, there is a shared area between the waste liquid chamber and the fuel tank. During use, the volume displacement is used to continuously adjust the volume of the waste liquid chamber and the fuel tank. Although the entire hydrogen generator has a compact structure, the reaction chamber and the waste liquid chamber must use pressure-resistant and high-temperature resistant materials. The waste liquid is not easy to clean and cannot be reused, and the cost of use is high. In order to reuse the reaction tube and catalyst multiple times, the byproduct sodium metaborate is directly discharged from the system through the waste liquid pipeline. However, since the solubility of the generated waste liquid sodium metaborate is very low, and its solubility is closely related to temperature, it is easy to get blocked during the discharge from the reaction tube, especially in a low temperature environment.

[0004] In order to reduce blockage and improve the adaptability to low-temperature environments, the first option is to reduce the concentration of the sodium borohydride solution so that there is enough water in the waste liquid, but this will reduce the hydrogen storage capacity of the sodium borohydride solution and thus reduce the overall energy density; the second option is to locally heat the drain pipe, but this will increase the system power consumption and also reduce the overall efficiency and energy density; the third option is to increase the exhaust frequency, but this will cause hydrogen waste and also reduce the overall energy density of the system. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides an efficient and environmentally friendly hydrolysis hydrogen production system that can be used in a low temperature environment, which overcomes the deficiencies of the prior art. The separated liquid is discharged into the fuel tank again through a gas-liquid separator, so that the fuel concentration in the fuel tank can be continuously reduced as the reaction proceeds, thereby reducing the concentration of by-products and the viscosity of by-products in the hydrolysis hydrogen production reactor, and then reducing the possibility of blockage of the waste liquid outlet; at the same time, by setting a waste liquid recovery bottle, the reaction by-products can be collected and recovered at any time to reduce environmental pollution. At the same time, the liquid level sensor in the hydrolysis hydrogen production reactor is set to control the discharge frequency, reduce the residence time of the waste liquid in the hydrolysis hydrogen production reactor and the seventh pipeline, and allow the waste liquid to quickly enter the waste liquid recovery bottle. The residual liquid that has not reacted fully can continue to react in the waste liquid recovery bottle to improve the hydrogen production efficiency, thereby further improving the hydrolysis hydrogen production efficiency. The pipeline and waste liquid air inlet before entering the waste liquid recovery bottle are covered with insulation materials. The temperature of the reaction waste liquid in the waste liquid recovery bottle is relatively high. In addition, there is heat release from the residual liquid reaction inside, which makes the temperature inside the waste liquid recovery bottle and the liquid inlet relatively high, avoiding the possibility of blockage in the discharge pipe, so that the hydrolysis hydrogen production system can be used in low temperature environments.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0023] Embodiment 1, as Figure 1 to Figure 2As shown, a highly efficient, environmentally friendly, low-temperature hydrogen production system by hydrolysis includes a fuel tank 1, a hydrogen production reactor by hydrolysis 2, a gas-liquid separator 3, and a waste liquid recovery bottle 4. The inner cavity of the fuel tank 1 is connected to the input end of a feed pump 6 through a first pipeline 5, and the output end of the feed pump 6 is connected to the material inlet end of the hydrogen production reactor by hydrolysis 2 through a second pipeline 7. A hydrogen outlet is provided at the top of the hydrogen production reactor 2, and the hydrogen outlet is connected to the inlet end of the gas-liquid separator 3 through a third pipeline 8. The gas outlet end of the gas-liquid separator 3 is connected to the inlet end of a filter 11 through a fourth pipeline 10, and the outlet end of the filter 11 is connected to a fuel cell 9 through a fifth pipeline 12. The liquid outlet end of the gas-liquid separator 3 is connected to the inner cavity of the fuel tank 1 through a sixth pipeline 13.

[0024] A liquid inlet 14, an air outlet 15 and a safety valve 16 are respectively arranged on the top of the waste liquid recovery bottle 4, and a waste liquid outlet is arranged at the bottom of the hydrolysis hydrogen production reactor 2. The waste liquid outlet is connected to the liquid inlet 14 through the seventh pipeline 17, and the air outlet 15 is connected to the inlet end of the filter 11 through the eighth pipeline 18. The outer surfaces of the waste liquid recovery bottle 4, the seventh pipeline 17 and the liquid inlet 14 are covered with thermal insulation cotton to play a thermal insulation role.

[0025] Working principle:

[0026] The hydride aqueous solution in the fuel tank 1 is first transported to the hydrolysis hydrogen production reactor 2 through the feed pump 6, and a hydrolysis reaction occurs under the action of the catalyst in the hydrolysis hydrogen production reactor 2. The generated hydrogen enters the gas-liquid separator 3 through the third pipeline 8 for gas-water separation, and the separated hydrogen is transported to the filter 11 through the fourth pipeline 10 for further filtration treatment. In this embodiment, the filter 11 can be composed of a strong acid ion exchange resin and a shell; the filtered hydrogen enters the fuel cell stack to react and generate electricity. The liquid separated by the gas-liquid separator 3 is discharged into the fuel tank 1 again through the sixth pipeline 13, so that the fuel concentration in the fuel tank 1 can be continuously reduced as the reaction proceeds, thereby reducing the concentration of by-products and the viscosity of by-products in the hydrolysis hydrogen production reactor 2, and then reducing the possibility of blockage of the waste liquid outlet; the by-products generated by the hydrolysis hydrogen production reactor 2 after the hydrolysis reaction enter the waste liquid recovery bottle 4 through the seventh pipeline 17. In this embodiment, the waste liquid recovery bottle 4 has a certain heat preservation effect and can be pre-placed with trace catalyst particles or catalyst solution. Therefore, the residual liquid that has not reacted fully into the waste liquid recovery bottle 4 can continue to react under high temperature or under the action of high temperature and catalyst. The accumulated hydrogen after the reaction will flow to the inlet end of the filter 11 through the eighth pipeline 18, and then enter the fuel cell 9 stack after further filtering to react and generate electricity, thereby further improving the efficiency of hydrogen production by hydrolysis. In addition, the waste liquid in the hydrolysis hydrogen production reactor 2 directly enters the waste liquid recovery bottle 4 through the seventh pipeline 17. By insulating the seventh pipeline 17 and the liquid inlet 14, the probability of blockage in the waste liquid outlet at the bottom of the hydrolysis hydrogen production reactor 2 is further reduced.

[0027] In the whole system, the waste liquid recovery bottle 4 is a low-pressure reaction device (≤1bar), which is a low-pressure passage, and the hydrolysis hydrogen production reactor 2 and the gas-liquid separator 3 are high-pressure reaction devices, with a pressure range of 2-8bar, which is a high-pressure passage. Among them, the hydride aqueous solution in the fuel tank 1 can adopt hydride aqueous solutions such as sodium borohydride, lithium borohydride, LiAlH4, etc. In this embodiment, a sodium borohydride aqueous solution with a concentration of 15-30wt% is adopted, and a sodium hydroxide alkaline stabilizer with a concentration of 1-10wt% is adopted. In addition, a gas permeable membrane component is installed on the fuel tank 1 to balance the internal and external air pressures of the fuel tank 1. Among them, the fuel cell 9 is a proton exchange membrane fuel cell, which adopts hydrogen as the anode reactant and air or oxygen as the cathode reactant.

[0028] Embodiment 2, as a further preferred embodiment of embodiment 1, a drain valve 19 is provided at the waste liquid outlet of the hydrolysis hydrogen production reactor 2, a first liquid level sensor is installed inside the hydrolysis hydrogen production reactor 2, a drain valve 20 is provided at the liquid outlet end of the gas-liquid separator 3, a second liquid level sensor is installed inside the gas-liquid separator 3, the signal output ends of the first liquid level sensor and the second liquid level sensor are respectively connected to the signal input ends of the control system, and the signal output ends of the control system are respectively connected to the drain valve 19 and the drain valve 20.

[0029] When the waste liquid content in the hydrogen production reactor 2 by hydrolysis reaches the first liquid level sensor, the first liquid level sensor will transmit a signal to the control system, and the control system will control the drain valve 19 to open, so that the waste liquid in the hydrogen production reactor 2 is output to the waste liquid recovery bottle 4 through the seventh pipeline 17; when the water level in the gas-liquid separator 3 reaches the second liquid level sensor, the second liquid level sensor will transmit a signal to the control system, and the control system will control the drain valve 20 to open, so that the liquid in the gas-liquid separator 3 is discharged into the fuel tank through the sixth pipeline 13, so that the fuel concentration can be continuously diluted with the hydrogen production process. In this embodiment, the drain valve 19 and the drain valve 20 can be a pinch valve, a solenoid valve or a micro peristaltic pump. In addition, since the residual liquid that has not reacted fully into the waste liquid recovery bottle 4 can continue to react under high temperature or high temperature and catalyst, the liquid level sensor in the hydrogen production reactor 2 can be set to appropriately increase the drainage frequency to reduce the residence time of the waste liquid in the hydrogen production reactor 2 and the seventh pipeline 17, thereby further reducing the possibility of pipeline blockage.

[0030] Embodiment 3, as a further preferred embodiment of embodiment 1, a first pressure sensor 21 is provided on the third pipeline 8, and the signal output end of the first pressure sensor 21 is connected to the signal input end of the control system, and the signal output end of the control system is connected to the feed pump 6. The degree of the first pressure sensor 21 can be used to control the rotation speed of the feed pump 6, and then control the speed at which the hydride aqueous solution in the fuel tank 1 enters the hydrolysis hydrogen production reactor 2.

The pressure reducing valve 22 can be used to reduce the pressure of the hydrogen output from the gas outlet of the gas-liquid separator 3; the second pressure sensor 23 is used to detect the pressure of the output hydrogen, and when the pressure reaches the set value, the control system controls the solenoid valve 24 to open, so that the output hydrogen enters the fuel cell stack to react and generate electricity. By providing a one-way valve 25 on the sixth pipeline 13 and the eighth pipeline 18, hydrogen and liquid are prevented from flowing back.

[0032] Embodiment 5, as a further preferred embodiment of embodiment 4, the bottle body of the waste liquid recovery bottle 4 adopts a foldable structure. In this embodiment, a corrugated tube structure can be adopted, and the waste liquid recovery bottle 4 is made of a high temperature resistant rubber material or plastic material. In this embodiment, the waste liquid recovery bottle 4 is made of a silicone material, and the bottle body of the waste liquid recovery bottle 4 is foldable, so it is small in size and easy to carry. In addition, a liquid inlet quick connector is fixedly installed on the liquid inlet 14, and a gas outlet quick connector is fixedly installed on the gas outlet 15; the liquid inlet 14 can be quickly connected to the end of the seventh pipeline 17 through the liquid inlet quick connector, and the gas outlet 15 can be quickly connected to the end of the eighth pipeline 18 through the gas outlet quick connector. Therefore, the waste liquid recovery bottle 4 can be replaced at any time during the hydrogen production process.

[0033] Embodiment 6, as a further preferred embodiment of embodiment 4, a third liquid level sensor 26 is provided in the inner cavity of the waste liquid recovery bottle 4, and the signal output end of the third liquid level sensor 26 is connected to the signal input end of the control system. When the waste liquid content in the waste liquid recovery bottle 4 reaches the third liquid level sensor 26, the third liquid level sensor 26 will transmit a signal to the control system, and the control system will remind the staff to replace the waste liquid recovery bottle 4.

The temperature in the hydrolysis hydrogen production reactor 2 can be detected in real time by the temperature sensor. When the temperature in the hydrolysis hydrogen production reactor 2 reaches a certain value, the cooling fan can be controlled to run to dissipate heat for the hydrolysis hydrogen production reactor 2, so that the temperature of the hydrolysis hydrogen production reactor 2 is controlled between 50-90°C.
