Description

Technical Field

[0001] This utility model relates to the field of hydrogen production equipment technology, specifically to a reaction material input mechanism for a hydrogen production device. Background Technology

[0002] There are various methods for producing hydrogen, which can be divided into several categories depending on the raw materials, energy sources, and technical routes. The fossil fuel reforming method, which produces hydrogen by reacting hydrocarbons or hydrogen-containing fuels with steam or oxygen, is currently the main method of industrial hydrogen production (accounting for about 95% of global hydrogen production). Its production principle is: CH4 + H2O → CO + 3H2 (under high temperature catalyst), and the yield is further improved by water-gas shift reaction (CO + H2O → CO2 + H2).

[0003] Since natural gas contains a certain amount of sulfides, these sulfides (such as H2S) can poison the catalyst during the reaction, thus affecting the reaction efficiency and hydrogen production efficiency, and further impacting hydrogen production.

[0004] Therefore, a reaction material input mechanism for a hydrogen production device capable of absorbing sulfides from natural gas is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a reaction material input mechanism for a hydrogen production device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A reaction material input mechanism for a hydrogen production device includes:

[0008] A purification chamber, wherein an air inlet pipe is connected to one side of the top of the purification chamber and extends to the bottom of the purification chamber, and an air pump is connected to the other side of the top of the purification chamber, and an air outlet pipe is connected to the outlet of the air pump.

[0009] A purification component for removing hydrogen sulfide gas from natural gas. The purification component includes an alkaline solution filled in a purification chamber. A drive cylinder is fixedly connected to the top wall of the purification chamber. Multiple connecting frames are evenly arranged at the bottom end of the drive cylinder. Multiple nozzles are evenly fixedly installed at the bottom end of the connecting frames.

[0010] A regeneration component is used to regenerate an alkaline solution saturated with hydrogen sulfide so that the alkaline solution can be reused. The regeneration component includes a heating tube disposed at the bottom of the purification chamber.

[0011] Preferably, a connecting pipe is rotatably installed inside the drive cylinder, and the top end of the connecting pipe has a through hole that communicates with the connecting frame and the nozzle.

[0012] Preferably, multiple actuating plates are uniformly fixedly installed on the side wall at the top of the drive cylinder.

[0013] Preferably, a water pump is fixedly installed on the side wall of the purification box, the inlet of the water pump is connected to a water inlet pipe, the bottom end of the water inlet pipe is connected to the bottom end of the purification box, the outlet of the water pump is connected to a water injection pipe, and the other end of the water injection pipe is connected to the side wall of the drive cylinder.

[0014] Preferably, the water injection pipe is tangent to the side wall of the drive cylinder, and a baffle is provided at the top of the purification box near the air pump.

[0015] Preferably, a controller connected to the heating tube is fixedly installed on the side wall at the bottom of the purification box.

[0016] Preferably, an exhaust pipe is connected to the side wall at the top of the purification box, a solenoid valve is connected to the exhaust pipe near the purification box, and an exhaust fan is also provided at the end of the exhaust pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By setting up purification components, after the water pump starts working, the water pump, through the inlet pipe and the injection pipe, can drive the alkaline solution in the purification tank to circulate. The through hole at the top of the connecting pipe allows the alkaline solution to easily enter the nozzle on the connecting frame, facilitating the spraying of the alkaline solution. This ensures that the alkaline solution is evenly mixed with the natural gas, facilitating the complete purification of hydrogen sulfide gas in the natural gas and ensuring the purification effect. After the alkaline solution enters the drive cylinder, it can push the actuating plate, which in turn drives the connecting pipe to rotate. The connecting pipe, in turn, drives the nozzle on the connecting frame to rotate. At this time, the alkaline solution sprayed by the nozzle has a larger centrifugal force range, which can further purify the overflowing natural gas, thereby improving the purification effect.

[0019] 2. By setting up a regeneration component, the controller can activate the heating element, which heats the alkaline solution after absorbing hydrogen sulfide gas. This causes the hydrogen sulfide gas in the alkaline solution to be released, allowing the alkaline solution to continue absorbing hydrogen sulfide gas from natural gas. This enables the alkaline solution to be reused, reducing its consumption and ensuring continuous absorption. Furthermore, opening the solenoid valve activates the exhaust fan, which drives the hydrogen sulfide gas decomposed in the purification chamber out through the exhaust pipe. This prevents the hydrogen sulfide gas from entering the hydrogen production unit and allows for the separate guidance of the hydrogen sulfide gas, which is beneficial for hydrogen production.

[0027] Please see Figures 1 to 4 ,

[0028] A reaction material input mechanism for a hydrogen production device includes:

[0029] Purification box 1, with an air inlet pipe 6 connected to one side of the top of purification box 1 and the air inlet pipe 6 extending to the bottom of purification box 1, and an air pump 4 connected to the other side of the top of purification box 1, with an air outlet pipe 3 connected to the outlet of air pump 4.

[0030] The purification component is used to remove hydrogen sulfide gas from natural gas. The purification component includes an alkaline solution filled in the purification box 1.

[0031] The regeneration component is used to regenerate the alkaline solution after it has been saturated with hydrogen sulfide so that the alkaline solution can be reused. The regeneration component includes a heating tube 13 located at the bottom of the purification chamber 1.

[0032] In this embodiment, after natural gas is introduced into the purification box 1 through the inlet pipe 6, when the natural gas overflows from the alkaline solution, the purification component can absorb the hydrogen sulfide gas in the natural gas, and the regeneration component is used to regenerate the alkaline solution after it is saturated with hydrogen sulfide, so that the alkaline solution can be reused. The purified natural gas can be injected into the hydrogen production equipment from the outlet pipe 3 by the gas pump 4.

[0033] As one embodiment of this utility model, please refer to Figure 2 A connecting pipe 15 is rotatably installed inside the drive cylinder 10. The top end of the connecting pipe 15 has a through hole 17 that communicates with the connecting frame 12 and the nozzle 14.

[0034] In this embodiment, the through hole 17 at the top of the connecting pipe 15 allows the alkaline solution to easily enter the nozzle 14 on the connecting frame 12, facilitating the spraying of the alkaline solution and enabling the alkaline solution to be evenly mixed with the natural gas, thus facilitating the complete purification of hydrogen sulfide gas in the natural gas.

[0035] As one embodiment of this utility model, please refer to Figure 3 Multiple actuating plates 16 are evenly fixedly installed on the side wall at the top of the drive cylinder 10.

[0036] In this embodiment, the actuating plate 16 can provide a bearing surface for the connecting pipe 15, which is beneficial to the rotation of the connecting pipe 15.

[0037] As one embodiment of this utility model, please refer to Figure 4 A water pump 5 is fixedly installed on the side wall of the purification box 1. The inlet of the water pump 5 is connected to a water inlet pipe 18, and the bottom end of the water inlet pipe 18 is connected to the bottom end of the purification box 1. The outlet of the water pump 5 is connected to a water injection pipe 19, and the other end of the water injection pipe 19 is connected to the side wall of the drive cylinder 10.

[0038] In this embodiment, the water pump 5 can drive the alkaline solution in the purification tank 1 to circulate and spray it evenly in the purification tank 1 through the nozzle 14, so that the alkaline solution can come into uniform contact with the natural gas, fully absorb the hydrogen sulfide gas mixed in the natural gas, and ensure the purification effect.

[0039] As one embodiment of this utility model, please refer to Figure 2 The water injection pipe 19 is tangent to the side wall of the drive cylinder 10, and a baffle 11 is provided at the top of the purification box 1 near the air pump 4.

[0040] In this embodiment, the alkaline solution can be circulated into the drive cylinder 10 through the water injection pipe 19, which can provide power for the rotation of the actuating plate 16, and the baffle 11 can prevent the alkaline solution sprayed from the nozzle 14 from splashing onto the air pump 4, thus ensuring the purification effect.

[0041] As one embodiment of this utility model, please refer to Figure 2 A controller 2, which is connected to the heating tube 13, is fixedly installed on the side wall at the bottom of the purification box 1.

[0042] In this embodiment, the controller 2 can activate the heating tube 13, which can heat the alkaline solution after absorbing hydrogen sulfide gas, thereby releasing the hydrogen sulfide gas from the alkaline solution. This allows the alkaline solution to continue absorbing hydrogen sulfide gas from natural gas, enabling the alkaline solution to be reused, reducing its consumption, and ensuring its continuous absorption effect.

[0043] As one embodiment of this utility model, please refer to Figure 4 An exhaust pipe 8 is connected to the side wall at the top of the purification box 1. A solenoid valve 7 is connected to the exhaust pipe 8 near the purification box 1. An exhaust fan 9 is also installed at the end of the exhaust pipe 8.

[0044] In this embodiment, after the solenoid valve 7 is opened, the exhaust fan 9 is started. The exhaust fan 9 can drive the hydrogen sulfide gas decomposed by heating in the purification box 1 to be discharged outward through the exhaust pipe 8, which can prevent the hydrogen sulfide gas from entering the hydrogen production device. It can guide the hydrogen sulfide gas separately, which is beneficial to the preparation of hydrogen.

[0045] Working Principle: First, natural gas is introduced into the purification tank 1 through the intake pipe 6. When the natural gas overflows from the alkaline solution, the alkaline solution at the bottom of the purification tank 1 can initially absorb part of the hydrogen sulfide gas in the natural gas. After the water pump 5 starts working, the water pump 5, through the water inlet pipe 18 and the water injection pipe 19, can drive the alkaline solution in the purification tank 1 to circulate. The through hole 17 at the top of the connecting pipe 15 allows the alkaline solution to easily enter the nozzle 14 on the connecting frame 12, facilitating the spraying of the alkaline solution and ensuring that the alkaline solution is evenly mixed with the natural gas, thus facilitating the complete purification of the hydrogen sulfide gas in the natural gas and ensuring the purification effect. After the alkaline solution enters the drive cylinder 10, it can push the actuating plate 16, which in turn drives the connecting pipe 15 to rotate. The connecting pipe 15 can then drive the nozzle 14 on the connecting frame 12 to rotate. At this time, the alkaline solution sprayed by the nozzle 14 has a larger centrifugal force range, which can further amplify the overflow. The natural gas is purified again, which can improve the purification effect. The baffle 11 can prevent the alkaline solution sprayed from the nozzle 14 from splashing onto the gas pump 4. When the alkaline solution is saturated, the controller 2 can start the heating tube 13. The heating tube 13 can heat the alkaline solution after absorbing hydrogen sulfide gas, which can release the hydrogen sulfide gas in the alkaline solution, so that the alkaline solution can continue to absorb hydrogen sulfide gas in the natural gas. The alkaline solution can be reused, which can reduce the consumption of alkaline solution and ensure the continuous absorption effect of alkaline solution. After the solenoid valve 7 is opened, the exhaust fan 9 is started. The exhaust fan 9 can drive the hydrogen sulfide gas heated and decomposed in the purification box 1 to be discharged out through the exhaust pipe 8, which can prevent hydrogen sulfide gas from entering the hydrogen production device. It can guide the hydrogen sulfide gas separately, which is beneficial to the preparation of hydrogen. The purified natural gas can be injected into the hydrogen production equipment by the gas pump 4 from the gas outlet pipe 3.
