Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production and power generation equipment, and particularly relates to a water-hydrogen generator with a multifunctional raw material tank. Background Art

[0002] Hydrogen is one of the most ideal energy sources in the 21st century. When burning the same weight of coal, gasoline, and hydrogen, hydrogen generates the most energy, and its combustion product is water, without ash and waste gas, and does not pollute the environment; while the main products of coal and oil combustion are CO2 and SO2, which can cause the greenhouse effect and acid rain respectively. The reserves of coal and oil are limited, while hydrogen mainly exists in water, and the only product after combustion is also water, so hydrogen can be continuously produced and will never be used up. Hydrogen is widely distributed. Water is a large "warehouse" of hydrogen, which contains 11% hydrogen. There is about 1.5% hydrogen in the soil; hydrogen is contained in petroleum, coal, natural gas, and animal and plant bodies, etc. The main body of hydrogen exists in the form of compound water, and about 70% of the earth's surface is covered by water, with a large water storage capacity. Therefore, it can be said that hydrogen is an energy source that "is inexhaustible and never runs out". If hydrogen can be produced by a suitable method, then hydrogen will also be a relatively cheap energy source.

[0003] Currently, by using the methanol steam reforming technology to produce a mixed gas of H2 and CO2, and then separating it through a palladium membrane separator, H2 and CO2 can be obtained respectively. Referring to Chinese Invention CN201510476342.5, this patent discloses a methanol steam reforming hydrogen production generator. Methanol and steam are in the reforming chamber of the reformer, and under the temperature condition of 350 - 409 °C and the pressure condition of 1 - 5 MPa, through a catalyst, under the action of the catalyst, a methanol cracking reaction and a carbon monoxide shift reaction occur to generate hydrogen and carbon dioxide. This is a multi-component and multi-reaction gas-solid catalytic reaction system. The reaction equations are as follows: (1) CH3OH → CO + 2H2; (2) H2O + CO → CO2 + H2; (3) CH3OH + H2O → CO2 + 3H2. The H2 and CO2 generated by the reforming reaction are then separated by the palladium membrane separator in the separation chamber to obtain high-purity hydrogen. The obtained high-purity hydrogen then enters the fuel cell. In the fuel cell, hydrogen and oxygen in the air undergo an electrochemical reaction to generate electric energy. At the anode of fuel cell 1: 2H2 → 4H + + 4e - , H2 splits into two protons and two electrons. The protons pass through the proton exchange membrane (PEM), and the electrons pass through the anode plate, through the external load, and enter the cathode bipolar plate. At the cathode of fuel cell 1: O2 + 4e - + 4H +→ 2H2O, protons, electrons and O2 recombine to form H2O. This generator integrates methanol-water reforming hydrogen production with a fuel cell, achieving the technical purpose of combining hydrogen production and power generation. However, the technical problems existing in the invention patent CN201510476342.5 are as follows: First, relying only on two ordinary fans for air extraction, the air extraction effect of ordinary fans is poor, and the patent does not set up an air collecting hood and a flow guiding hood, which will cause the air to be very uneven when passing through the fuel cell, reducing the power generation efficiency and cooling efficiency of the fuel cell, and the temperatures of various parts of the fuel cell are unbalanced; Second, the temperature of the tail gas discharged from the methanol-water reformer is relatively high, which is likely to affect the mechanisms around the tail gas window and cannot cool the methanol-water reformer; Third, it is necessary to install a heavy steel bearing support frame to support and protect the fuel cell and the methanol-water reformer, and the steel bearing support frame has no buffering force on the fuel cell and the methanol-water reformer, and its protection strength is not good enough; Fourth, it is necessary to additionally configure a methanol-water raw material tank to supply methanol-water raw materials to the methanol-water reformer; Fifth, a large amount of space inside the casing of the methanol-water reforming hydrogen generator is wasted and cannot be utilized; Sixth, the noise generated by the fan is relatively large, and no noise reduction treatment is carried out on the fan.

[0004] With the progress of technology, the applicant has developed a new type of methanol-water reforming hydrogen generator. See Chinese Patent Application No. 202221987299.0, and see Figure 1 and Figure 2, the new methanol steam reforming hydrogen generator includes a methanol-water raw material tank 100 and a generator body 200. The methanol-water raw material tank 100 supplies methanol-water raw materials to the generator body 200 through a conveying pipeline 101. The generator body 200 includes a steel bearing support frame 201. Above the steel bearing support frame 201, a fuel cell power generation system and a methanol steam reforming hydrogen production system are installed. Among them, the fuel cell power generation system includes an air filter 202, a fuel cell 203, a wind collecting hood 204, and a wind guiding hood 205 from right to left in sequence. A centrifugal fan 206 is installed in the wind guiding hood 205. Under the action of the centrifugal fan 206, the outside air can be discharged after passing through the air filter 202, the fuel cell 203, the wind collecting hood 204, and the wind guiding hood 205 in sequence. The methanol steam reforming hydrogen production system is arranged on one side of the centrifugal fan 206. The methanol steam reforming hydrogen production system includes a methanol steam reformer 207. The air discharged from the fuel cell power generation system is blown onto the methanol steam reformer 207 and finally discharged from the left side of the generator body 200. The generator body 200 also includes a control device 208 and a casing 209. The control device 208 is installed on the side of the methanol steam reformer 207. Compared with the invention patent CN201510476342.5, the new methanol steam reforming hydrogen generator can make the air more uniform when passing through the fuel cell due to the setting of the wind collecting hood, the air guiding hood, and the centrifugal fan, so that the fuel cell has higher power generation efficiency and cooling efficiency; in addition, since the air discharged from the fuel cell power generation system is blown onto the methanol steam reformer, it can be mixed with the tail gas of the chimney 210 of the methanol steam reformer to reduce the tail gas temperature of the methanol steam reformer.

[0005] However, Figure 1 and Figure 2The novel methanol-water reforming hydrogen generation generator shown above also has the following technical defects: (1) After the air discharged from the fuel cell is mixed with the tail gas discharged from the chimney 210 of the methanol-water reformer, it will easily enter the body of the methanol-water reforming hydrogen generation generator in sequence. The relatively high-temperature gas is likely to have an adverse impact on the mechanisms around the tail gas window; (2) It is necessary to install a heavy steel bearing support frame 201 to support and protect the fuel cell and the methanol-water reformer. The weight of the steel bearing support frame 201 is about 8-12 kg, and the steel bearing support frame has no buffering force on the fuel cell and the methanol-water reformer, and its protection strength is not good enough; (3) It is necessary to install an air collecting cover and a flow guiding cover. The air collecting cover and the flow guiding cover need to be manufactured and formed by using two sets of injection molds, with high manufacturing costs and inconvenient installation; (4) The temperature of each mechanism module of the fuel cell power generation system and the methanol-water reforming hydrogen generation system is unbalanced; (5) A large amount of space inside the casing of the methanol-water reforming hydrogen generation generator is wasted and cannot be utilized; (6) There is no sound insulation device outside the centrifugal fan 206, and the noise of the methanol-water reforming hydrogen generation generator is still relatively large; (7) It is necessary to additionally configure a separate methanol-water raw material tank to supply methanol-water raw materials to the methanol-water reformer, which causes great inconvenience to transportation and use.

[0031] The structural principle and working principle of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] As Figures 3 - 7As shown in the figure, the present invention is a water-hydrogen generator with a multi-functional raw material tank, including a first multi-functional raw material tank 1. The first multi-functional raw material tank 1 is provided with a first methanol-water raw material bin 11 for storing methanol-water raw materials. Inside the first multi-functional raw material tank 1, there is a power generation system accommodation cavity 12. Inside the power generation system accommodation cavity 12, a fuel cell power generation system 300 is installed. The fuel cell power generation system 300 includes an air filter 2, a fuel cell 3, a wind collection cavity, a wind guiding cavity, and a centrifugal fan 4. The first methanol-water raw material bin 11 surrounds the outside of the fuel cell power generation system. The power generation system accommodation cavity 12 includes a first cavity part 121, a second cavity part 122, a third cavity part 123, and a fourth cavity part 124 arranged in sequence from right to left. The air filter 2 is accommodated inside the first cavity part 121. The fuel cell 3 is accommodated inside the second cavity part 122. The inner cavity wall of the third cavity part 123 constitutes the wind collection cavity of the fuel cell power generation system 300. The inner cavity wall of the fourth cavity part 124 constitutes the wind guiding cavity of the fuel cell power generation system 300. The centrifugal fan 4 is installed in the fourth cavity part 124. Under the air extraction action of the centrifugal fan 4, the outside air can pass through the air filter 2, the fuel cell 3, the wind collection cavity, and the wind guiding cavity in sequence and then be discharged.

[0033] The fuel cell 3 of the fuel cell power generation system 300 of the present invention is used for the electrochemical reaction between hydrogen and oxygen in the air to generate electric energy. At the anode of the fuel cell 3: 2H2 → 4H + +4e - , H2 splits into two protons and two electrons. The protons pass through the proton exchange membrane (PEM), and the electrons pass through the anode plate, pass through the external load, and enter the cathode bipolar plate. At the cathode of the fuel cell 3: O2 + 4e - +4H + →2H2O. The protons, electrons, and O2 recombine to form H2O. The generated electric energy is output through the power output port 6. Under the air extraction action of the centrifugal fan 4, the outside air passes through the air filter 2, the fuel cell 3, the wind collection cavity, and the wind guiding cavity in sequence and then is discharged. When the outside air enters the fuel cell 3, on the one hand, it dissipates heat and cools down the fuel cell 3, and on the other hand, it provides oxygen for the electrochemical reaction of the fuel cell 3. The hydrogen required for the fuel cell 3 to generate electricity comes from the methanol-water reforming hydrogen production system 400, and its structural function will be described in detail later.

[0034] As Figure 4 and Figure 5 shown, a control box accommodation cavity 125 is further provided at the lower end of the first multi-functional raw material tank 1. A water-hydrogen generator control device 5 is installed inside the control box accommodation cavity 125. A control main board is arranged inside the water-hydrogen generator control device 5, which is used to control the operation of the fuel cell power generation system 300 and the methanol-water reforming hydrogen production system 400.

[0035] As Figures 3 - 6 shown, a box side plate 6 is installed on the left side of the power generation system accommodation cavity 12. The left side of the centrifugal fan 4 is fixedly connected to the box side plate 6. The box side plate 6 is provided with a first exhaust hole 61 for exhausting air. The box side plate 6 can block the left side of the fourth cavity part 124, leaving only one first exhaust hole 61, so that the air extracted by the centrifugal fan 4 is discharged from the first exhaust hole 61.

[0036] As Figures 3 - 7 shown, the water-hydrogen generator further includes a second multi-functional raw material tank 7. The second multi-functional raw material tank 7 is arranged in parallel with the first multi-functional raw material tank 1. The second multi-functional raw material tank 7 is provided with a second methanol-water raw material bin 71 for storing methanol-water raw materials. A reforming system accommodation cavity 72 is arranged inside the second multi-functional raw material tank 7. A methanol-water reforming hydrogen production system 400 is installed inside the reforming system accommodation cavity 72. The second methanol-water raw material bin 71 surrounds the methanol-water reforming hydrogen production system 400. The second multi-functional raw material tank 7 has the following technical advantages: 1) Since the reforming system accommodation cavity 72 is arranged inside the second multi-functional raw material tank 7, the methanol-water reforming hydrogen production system 400 is installed inside the reforming system accommodation cavity 72, and the second methanol-water raw material bin 71 surrounds the methanol-water reforming hydrogen production system 400, therefore, the present invention does not need to additionally install a heavy steel bearing support frame to support the methanol-water reforming hydrogen production system 400, reducing the weight and cost. Moreover, the box body of the second multi-functional raw material tank 7 can play a role in protecting and supporting the methanol-water reforming hydrogen production system 400, having a buffering force and good protection strength; 2) The second multi-functional raw material tank makes full use of the space inside the methanol-water reforming hydrogen production generator, avoiding space waste; 3) The second multi-functional raw material tank 7 increases the accommodation capacity of the methanol-water raw materials.

[0037] The methanol steam reforming hydrogen production system 400 of the present invention includes a heat-insulating housing. Inside the heat-insulating housing, there are a reforming chamber, a separation chamber and a combustion chamber. The reforming chamber is used for the reforming reaction of methanol and water to produce a mixed gas mainly composed of carbon dioxide and hydrogen. A catalyst is provided in the reforming chamber. Methanol and water vapor pass through the catalyst in the reforming chamber under a pressure condition of 1-5 MPa. Under the action of the catalyst, a methanol cracking reaction and a carbon monoxide conversion reaction occur to generate hydrogen and carbon dioxide. This is a multi-component and multi-reaction gas-solid catalytic reaction system, and the reaction equations are: (1) CH3OH → CO + 2H2, (2) H2O + CO → CO2 + H2, (3) CH3OH + H2O → CO2 + 3H2, to produce a high-temperature mixed gas mainly composed of carbon dioxide and hydrogen; the separation chamber is used to separate hydrogen from the mixed gas, and the hydrogen can be output externally or supplied to a fuel cell; the combustion chamber is used for partial hydrogen produced to burn in the combustion chamber to provide heat for the operation of the reforming hydrogen production device; in addition, in the reforming hydrogen production device, there is also a heating and vaporizing coil. Before methanol and water raw materials enter the reforming chamber, they are first vaporized through the heating and vaporizing coil.

[0038] As Figures 3 - 7 shown, the methanol steam reforming hydrogen production system 400 is provided with an exhaust gas discharge window 401. After partial hydrogen produced burns in the combustion chamber, its exhaust gas is discharged from the exhaust gas discharge window 401; the second multi-functional raw material tank 7 is provided with a second exhaust hole 73 that penetrates left and right at a position corresponding to the exhaust gas discharge window 401, and the second exhaust hole 73 is communicated with the first exhaust hole 61. Since the second exhaust hole 73 is communicated with the first exhaust hole 61, the air extracted from the centrifugal fan 4 will directly blow to the position of the exhaust gas discharge window 401 in the second exhaust hole 73 and quickly mix with the exhaust gas discharged from the exhaust gas discharge window 401, so that the high-temperature exhaust gas is quickly cooled and then discharged outward, and the mixed gas will be discharged from the second exhaust hole 73 to the third exhaust hole 91 (its structure will be described in detail later), and finally discharged to the outside from the third exhaust hole 91. This discharge process can prevent the exhaust gas from entering the body of the methanol steam reforming hydrogen production generator and avoid adverse effects of the exhaust gas on the body structure.

[0039] As Figures 3 - 7As shown, the water-hydrogen generator further includes a bottom plate 13, a right side plate 10, a left side plate 9, and an outer cover plate 8; the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7 are arranged in parallel on the bottom plate 13; the right side plate 10 is installed on the right side of the first multi-functional raw material tank 1, and the lower end of the right side plate 10 is connected to the right end of the bottom plate 13; the left side plate 9 is installed on the left side of the second multi-functional raw material tank 7, and the lower end of the left side plate 9 is connected to the left end of the bottom plate 13; the outer cover plate 8 includes a front side plate 81, an upper side plate 82, and a rear side plate 83 that are connected to each other. The outer cover plate 8 covers both the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7 at the same time. The right end of the outer cover plate 8 is connected to the right side plate 10, the left end of the outer cover plate 8 is connected to the left side plate 9, and the lower end of the outer cover plate 8 is connected to the bottom plate 13. A plurality of rolling wheels 131 are installed on the lower side of the bottom plate 13.

[0040] As Figures 3 - 7 shown, an air inlet window 101 is provided at the position of the right side plate 10 corresponding to the air filter 2, and a third exhaust hole 91 is provided at the position of the left side plate 9 corresponding to the tail gas discharge window 401. The third exhaust hole 91 is communicated with the second exhaust hole 73.

[0041] As Figure 4 and Figure 5 shown, the water-hydrogen generator further includes a reinforcing frame 14. The reinforcing frame 14 is sleeved outside both the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7 at the same time. The right side plate 10, the left side plate 9, and the outer cover plate 8 are installed outside the reinforcing frame. By providing the reinforcing frame 14, on the one hand, the second multi-functional raw material tank 7 can be tightly bundled with the first multi-functional raw material tank 1, and on the other hand, the anti-collision strength of the corners of the second multi-functional raw material tank 7 and the first multi-functional raw material tank 1 can be significantly increased.

[0042] As Figures 3 - 7 shown, a plurality of longitudinal and / or transverse grooves 15 are respectively provided on the front side, upper side, and rear side of the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7. A plurality of longitudinal and / or transverse ridges 84 are respectively provided on the inner sides of the front side plate 81, the upper side plate 2, and the rear side plate 83 of the outer cover plate 8. The positions of the ridges 84 correspond to those of the grooves 15, and the ridges 84 are embedded into the corresponding grooves 15. By providing the structure of the ridges 84 and the grooves 15, on the one hand, the outer cover plate 8 can be stably clamped with the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7, and on the other hand, the overall firmness and body strength of the water-hydrogen generator can be significantly improved.

[0043] As Figures 3 - 7As shown, the box body material of the first multi-functional raw material tank 1 is plastic, and the box body material of the second multi-functional raw material tank 7 is plastic or metal. Among them, the plastic is preferably PE polyethylene material; the first multi-functional raw material tank 1 and the second multi-functional raw material tank 7 are respectively injection molded by an injection molding machine. A methanol-water raw material addition port 16 is provided on the upper side of the first multi-functional raw material tank 1 and / or the second multi-functional raw material tank 7, and a feed hole 85 is opened at the position of the outer cover plate 8 corresponding to the methanol-water raw material addition port 16.
