Description

Technical Field

[0001] This utility model relates to the field of gas reaction equipment technology, and in particular to a gas reactor and a hydrogen generator. Background Technology

[0002] The gas reactor is a key piece of equipment in hydrogen production facilities, used to convert water and methanol or other raw materials into hydrogen.

[0003] Existing gas reactors typically use heat transfer oil for heating during the reaction. Heat transfer oil is filled into the reactor and heated, and gas is introduced to react under the action of a catalyst. However, the heat required by the gas varies at different stages of the reaction. Heating with heat transfer oil results in a uniform heating temperature within the reactor, leading to incomplete gas reaction, low conversion rate, slow heating of the heat transfer oil, significant heat loss, and a tendency to coke and clump after prolonged use, requiring regular replacement of the heat transfer oil. Utility Model Content

[0004] The main objective of this invention is to provide a gas reactor to solve the problem of insufficient gas reaction caused by the single and uncontrollable reaction temperature in existing reactors.

[0005] To achieve the above objectives, this utility model proposes a gas reactor, comprising:

[0006] The tower body has a reaction chamber for filling with a catalyst. The tower body is provided with an inlet and an outlet, which are sequentially connected.

[0007] An electric heating unit is provided in the tower body. The electric heating unit includes multiple electric heating tubes, which are spaced apart in the reaction chamber to form a reaction zone in the reaction chamber where the temperature decreases sequentially along the gas flow direction.

[0008] Optionally, the electric heating assembly includes multiple electric heating tubes of different lengths, which extend along the gas flow direction to form a reaction zone in the reaction chamber with the temperature decreasing sequentially along the gas flow direction.

[0009] Optionally, the electric heating tube assembly includes a first electric heating tube, a second electric heating tube, and a third electric heating tube with sequentially increasing lengths. The first electric heating tube, the second electric heating tube, and the third electric heating tube extend along the gas flow direction and are spaced apart from each other, so that a first reaction zone, a second reaction zone, and a third reaction zone with sequentially decreasing temperatures along the gas flow direction are formed in the reaction chamber.

[0010] Optionally, a distributor is provided in the reaction chamber, the distributor is located near the air inlet, the distributor is provided with a number of air passage holes and a number of mounting holes, and the electric heating tube passes through the mounting holes.

[0011] Optionally, the reaction chamber is provided with a flow guiding structure for guiding gas flow. The flow guiding structure is coiled between the air inlet and the air outlet to form a curved channel for gas flow.

[0012] Optionally, the flow guiding structure includes a plurality of baffles, with a gap formed between one side of the baffle and the cavity wall of the reaction chamber, and the plurality of baffles are staggered along the gas flow direction to form the curved channel.

[0013] Optionally, the flow guiding structure includes a spiral plate, which is arranged around the electric heating tube along the gas flow direction to form a spiral-shaped curved channel.

[0014] Optionally, the top of the tower body is provided with an explosion-proof wiring compartment, and the wiring terminals of multiple electric heating tubes are located in the explosion-proof wiring compartment for electrical connection with an external power source. The explosion-proof wiring compartment is filled with inert gas.

[0015] Optionally, the gas outlet is connected to a temperature sensor, which is used to detect the temperature of the reaction zone.

[0016] This utility model also proposes a hydrogen production machine, including a mixing station, an electric heating device, a purification device, and the aforementioned gas reactor, wherein the mixing station, the electric heating device, the purification device, and the gas reactor are connected by pipelines.

[0017] In this invention, the gas reactor tower has an inlet and an outlet. The reaction chamber of the tower is filled with a catalyst, and multiple electric heating tubes are installed within the reaction chamber to create reaction zones with progressively decreasing temperatures along the gas flow direction. When applied to methanol-water hydrogen production, methanol-water solution vapor enters the reaction chamber through the inlet. During the reaction, the gas undergoes endothermic and exothermic reactions sequentially. Since the endothermic reaction requires a large amount of heat, while the exothermic reaction requires a small amount, the multiple electric heating tubes gradually lower the temperature from the inlet to the outlet, creating reaction zones with different temperatures to meet the heat requirements of different reaction stages. This promotes complete gas reaction and improves hydrogen conversion efficiency. Simultaneously, the electric heating tubes have high and controllable heating efficiency and direct contact with the catalyst, effectively reducing heat loss and saving costs.

[0029] 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.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] See Figures 1 to 6 As shown, in one embodiment of the present invention, a gas reactor 100 includes: a tower body 10, the tower body 10 having a reaction chamber 11 for filling a catalyst, the tower body 10 having an inlet 12 and an outlet 13, the inlet 12, the reaction chamber 11 and the outlet 13 being sequentially connected; and an electric heating group disposed in the tower body 10, the electric heating group including multiple electric heating tubes 20, the multiple electric heating tubes 20 being spaced apart in the reaction chamber 11 so that a reaction zone 111 with a temperature decreasing sequentially along the gas flow direction is formed in the reaction chamber 11.

[0032] In the technical solution of this utility model, the tower body 10 of the gas reactor 100 has an inlet 12 and an outlet 13. The reaction chamber 11 of the tower body 10 is filled with a catalyst, and multiple electric heating tubes 20 are provided in the reaction chamber 11 to form a reaction zone 111 in which the temperature decreases sequentially along the gas flow direction. When applied to methanol-water hydrogen production, methanol-water solution vapor enters the reaction chamber 11 through the inlet 12. During the reaction, the gas undergoes endothermic and exothermic reactions sequentially. Since the endothermic reaction requires a large amount of heat and the exothermic reaction requires a small amount of heat, by setting multiple electric heating tubes 20, the temperature in the reaction chamber 11 gradually decreases from the inlet 12 to the outlet 13, forming reaction zones 111 with different temperatures to adapt to the heat requirements of different reaction stages of the gas, which is conducive to the full reaction of the gas and improves the hydrogen conversion efficiency. At the same time, the heating efficiency of the electric heating tubes 20 is high and controllable, and direct contact heating with the catalyst can effectively reduce heat loss and save costs.

[0033] It should be noted that when applied to hydrogen production, after the gas enters the reaction chamber 11, under the action of the catalyst, the initial stage of the reaction is a preheating and reforming stage, which is mainly an endothermic reaction and requires a large amount of heat. The final stage of the reaction is a conversion stage, which is mainly an exothermic reaction and requires a small amount of heat. It can be understood that the gas reactor 100 of this utility model can also be applied to fields such as petroleum refining and metallurgy that require gas heating and catalytic reactions. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model. Specifically, in this embodiment, the air inlet 12 is located near the top of the tower body 10, and the air outlet 13 is located near the bottom of the tower body 10, both connected to ventilation pipes. The electric heating group includes multiple electric heating tubes 20 and a controller (not shown in the figure) for controlling the heating of the electric heating tubes 20. The multiple electric heating tubes 20 are arranged in the reaction chamber 11. By setting the electric heating tubes 20 in different structures, different arrangements in the reaction chamber 11, or controlling the heating power, reaction zones 111 with different temperature zones can be formed in the reaction chamber 11. For example, in one embodiment, more electric heating tubes 20 are arranged near the air inlet 12 to form a heat matrix with a higher density; fewer electric heating tubes 20 are arranged near the air outlet 13 to form a heat matrix with a lower density; and a moderate number of electric heating tubes 20 are arranged in the middle area to transition and connect the upper and lower areas. The specific number depends on the actual situation. All electric heating tubes 20 are uniformly controlled in temperature. In this way, a reaction zone 111 with a gradually decreasing temperature from the air inlet 12 to the air outlet 13 can be formed in the reaction chamber 11. In another embodiment, multiple electric heating tubes 20 are spaced apart along the axis of the tower body 10 within the reaction chamber 11. The electric heating tubes 20 extend perpendicular to the axis of the tower body 10, dividing the chamber into multiple zones according to the different temperatures required for the reaction. The heating power of each electric heating tube 20 within each zone is controlled. By adjusting the heating power of the electric heating tubes 20, the temperature of each zone is adjusted to match the required reaction temperature. Thus, a reaction zone 111 with a gradually decreasing temperature from the inlet 12 to the outlet 13 is formed within the reaction chamber 11. This embodiment is not limited thereto, and all of the above are within the protection scope of this utility model. It is understood that the catalyst in the reaction chamber is filled with high, medium, and low temperature conversion catalysts according to different temperature zones. Preferably, the electric heating tube 20 in this embodiment is a U-shaped tube. The U-shaped tube structure has high thermal efficiency and uniform heating, good mechanical strength, and small space occupation. It can fill more catalyst in the reaction chamber 11, improve conversion efficiency, and the electric heating tube 20 does not need to be replaced even after long-term use. Of course, the electric heating tube 20 can also adopt spiral tube, straight tube, coil tube and other structures. This embodiment is not limited to this. All of the above are within the protection scope of this utility model.

[0034] Furthermore, a filling port is provided at the top of the tower body 10. The catalyst is filled into the reaction chamber 11 through the filling port. The filling port is connected to a flange as a sealing cover to prevent catalyst and / or gas leakage. Of course, the sealing cover can also adopt a rotating door structure connected by a hinge, or a compression sealing cover connected by a buckle, spring lock, etc., or a sealing cover that can be flipped and opened and closed 180° by a flipping mechanism. The specific choice depends on the actual situation and is not limited here.

[0035] See Figures 1 to 6 As shown, further, in one embodiment of this utility model, the electric heating assembly includes multiple electric heating tubes 20 of different lengths. These multiple electric heating tubes 20 extend along the gas flow direction, so that a reaction zone 111 is formed within the reaction chamber 11 with the temperature decreasing sequentially along the gas flow direction. Specifically, this embodiment provides multiple electric heating tubes 20 of different lengths, with at least one of each length. Since the gas flows from the top to the bottom of the tower due to gravity in this embodiment, the electric heating tubes 20 are also arranged to extend downwards from the top of the tower body 10. All electric heating tubes 20 have their heating power uniformly controlled. Figure 2 and Figure 3 As can be seen, due to the varying lengths of the electric heating tubes 20, the number of electric heating tubes 20 decreases closer to the bottom of the tower body 10. Short tubes are concentrated in the high-temperature heating zone, while long tubes cover the low-temperature zone. This means that the density of electric heating tubes 20 is highest at the top of reaction zone 111, decreasing progressively downwards. Therefore, the temperature of reaction zone 111 gradually decreases from the top to the bottom of the tower. It should be noted that the length and arrangement density of the electric heating tubes 20 are set according to the power requirements for gas reaction heat supply. The optimal length and arrangement density are calculated through simulation experiments to achieve uniform temperature in reaction zone 111. This setup, by adjusting the power density through electric heating tubes 20 of different lengths, achieves temperature zoning to adapt to the heat requirements of different reaction stages of the gas, resulting in more complete gas conversion in the catalytic reaction.

[0036] See Figures 1 to 6 As shown, further, in one embodiment of this utility model, the electric heating assembly includes a first electric heating tube 21, a second electric heating tube 22, and a third electric heating tube 23 with sequentially increasing lengths. The first electric heating tube 21, the second electric heating tube 22, and the third electric heating tube 23 extend along the gas flow direction and are spaced apart from each other, so that a first reaction zone 111a, a second reaction zone 111b, and a third reaction zone 111c with sequentially decreasing temperatures along the gas flow direction are formed in the reaction chamber 11. It should be noted that the electric heating tube 20 in this embodiment is configured as a tube of three lengths, wherein the first electric heating tube 21 is a short tube, the second electric heating tube 22 is a medium-length tube, and the third electric heating tube 23 is a long tube, so as to divide the reaction zone 111 into three temperature zones, wherein, as shown Figure 3As shown by the dashed lines, the area covered from the air inlet to the end of the first electric heating tube 21 forms the first reaction zone 111a, which is the preheating zone; the area covered from the end of the first electric heating tube 21 to the end of the second electric heating tube 22 forms the second reaction zone 111b, which is the main reaction zone 111; and the area covered from the end of the second electric heating tube 22 to the end of the third electric heating tube 23 forms the third reaction zone 111c, which is the stabilization / cooling zone. This arrangement allows the three reaction zones to cover different stages of the gas reaction, creating a reasonable temperature gradient to meet the heat requirements of different reaction stages. Furthermore, the reasonable spacing design reduces temperature interference between adjacent areas, improving energy utilization efficiency. Of course, it is also possible to set the reaction zones to two or four lengths, etc., depending on the actual reaction type, to divide the reaction zones into different numbers. This embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0037] See Figures 1 to 6 As shown, in one embodiment of this invention, a distributor 30 is provided inside the reaction chamber 11. The distributor 30 is located near the air inlet 12 and has several air passage holes and several mounting holes. The electric heating tube 20 passes through the mounting holes. It should be noted that the distributor 30 in this embodiment is a perforated plate-type flat distributor 30. When gas enters the reaction chamber 11 from the air inlet 12, the gas is first dispersed by the distributor 30 and then enters the reaction zone 111 through the air passage holes on the distributor 30. By setting the distributor 30, the gas distribution can be more uniform, and the gas can be more fully contacted with the catalyst during the reaction process, thereby improving the conversion efficiency. Of course, the distributor 30 can also be configured as an arc shape with several air passage holes on the arc plate; it can also be configured as a corrugated plate with a wavy or sawtooth surface and several air passage holes; it can also be configured as a multi-layer concentric ring arrangement with several air passage holes on the ring; as long as the gas can be dispersed, this embodiment is not limited to this, and all of the above are within the protection scope of this utility model.

[0038] See Figures 1 to 6 As shown, in one embodiment of this invention, a flow guiding structure 40 for guiding gas flow is provided in the reaction chamber 11. The flow guiding structure 40 is coiled between the gas inlet 12 and the gas outlet 13 to form a curved channel for gas flow. By providing the flow guiding structure 40 in the reaction chamber 11 to form a curved channel, the gas flows along the curved channel to the gas outlet 13 after entering the reaction chamber 11. In this way, the travel distance and residence time of the gas in the reaction zone 111 can be increased. The flow guiding design can break laminar flow and form turbulent flow, promote the mixing and contact of gas and catalyst, effectively reduce the reaction dead zone, and improve conversion efficiency.

[0039] See Figures 1 to 6As shown, further, in one embodiment of this utility model, the flow guiding structure 40 includes a plurality of baffles 41. A gap is formed between one side of each baffle 41 and the wall of the reaction chamber 11. The plurality of baffles 41 are staggered along the gas flow direction to form a curved channel. It should be noted that the flow guiding structure 40 of this embodiment is composed of a plurality of baffles 41. One side of each baffle 41 has a notch to form a gap with the wall of the reaction chamber 11 for gas passage. Adjacent baffles 41 partially overlap and their notches are staggered. The gas flow direction within the reaction chamber 11 is as follows: Figure 4 As shown, by setting multiple staggered baffles 41, a tortuous reaction channel is formed, which guides the gas flow. This allows the gas to flow along the baffles 41 throughout the reaction chamber 11, increasing the gas's travel distance and residence time in the reaction zone 111. This allows the gas to have more complete contact and reaction with the catalyst, effectively reducing dead zones and improving conversion efficiency. Of course, the baffles 41 can also be configured as guide vanes with guiding angles, spiral baffles, etc., as long as they can form multiple tortuous reaction channels to increase the gas travel distance. This embodiment is not limited to these, and all of the above are within the protection scope of this utility model.

[0040] See Figures 1 to 6 As shown, further, in one embodiment of this utility model, the flow guiding structure 40 includes a spiral plate, which is arranged around the electric heating tube 20 along the gas flow direction to form a spiral curved channel. It should be noted that the flow guiding structure 40 in this embodiment is a spiral plate (not shown in the figure), forming a structure similar to a spiral staircase within the reaction chamber 11, with the electric heating tube 20 spiraling around it. The spiral plate has a spiral channel, and the gas flows continuously from the inlet 12 along the spiral channel to the outlet 13. By setting the spiral plate, uniform radial and axial gas distribution can be achieved, increasing the gas's travel distance and residence time in the reaction zone 111, allowing for more complete contact and reaction between the gas and the catalyst, effectively reducing dead zones and improving conversion efficiency. Furthermore, the spiral plate is a continuous channel, resulting in lower flow resistance during gas flow. It is understood that the radius of the spiral plate and the angle of the flow guiding spiral can be adjusted to accommodate different gas flow rates, increasing the adaptability of the gas reactor 100.

[0041] See Figures 1 to 6As shown, in one embodiment of this utility model, the top of the tower body 10 is provided with an explosion-proof wiring compartment 50. The wiring terminals of multiple electric heating tubes 20 are located inside the explosion-proof wiring compartment 50 for electrical connection to an external power source. The explosion-proof wiring compartment 50 is filled with inert gas. It should be noted that in this embodiment, the top of the flange of the filling port is provided with an explosion-proof wiring compartment 50, which contains electrical components such as a power supply for supplying power to the electric heating tubes 20 and a controller for controlling the heating of the electric heating tubes 20. The wiring terminals of the multiple electric heating tubes 20 are electrically connected to the power supply. The explosion-proof wiring compartment 50 is filled with inert gas, which can be compressed air. With this configuration, even if there is an explosive gas leak, the explosive gas cannot enter the explosion-proof wiring compartment 50, ensuring the safety of the electrical components inside the explosion-proof wiring compartment 50 and preventing accidents.

[0042] See Figures 1 to 6 As shown, in one embodiment of this invention, a temperature sensor 60 is connected to the air outlet 13. The temperature sensor 60 is used to detect the temperature of the reaction zone 111. By setting the temperature sensor 60 on the external pipe connected to the air outlet 13 to detect and display the temperature inside the reaction chamber 11, the operator can monitor and adjust the temperature inside the reaction chamber 11 in real time.

[0043] This embodiment provides a hydrogen production machine, including a mixing station, an electric heating device, a purification device, and the aforementioned gas reactor 100. The mixing station, electric heating device, purification device, and gas reactor 100 are connected by pipelines. The gas reactor 100 includes a tower body 10 with a reaction chamber 11 for filling with a catalyst. The tower body 10 has an inlet 12 and an outlet 13, which are sequentially connected. An electric heating group is located in the tower body 10 and includes multiple electric heating tubes 20 spaced apart within the reaction chamber 11 to form a reaction zone 111 within the reaction chamber 11 where the temperature decreases sequentially along the gas flow direction. In this embodiment, the hydrogen generator produces hydrogen from methanol and water using the following reaction principle: CH3OH + H2O → CO2 + 3H2. The methanol-water mixture is mixed at a mixing station, heated by an electric heating device, and then introduced into the gas reactor 100 for hydrogen production. Because the gas reactor 100 is equipped with multiple electric heating tubes 20, the temperature within the reaction chamber 11 gradually decreases from the inlet 12 to the outlet 13, forming reaction zones 111 with different temperatures. This adapts to the heat requirements of different gas reaction stages, facilitating complete gas reaction and improving hydrogen conversion efficiency. Therefore, the crude hydrogen produced after the reaction is purified by a purification device to obtain pure hydrogen with a purity of up to 99.999%. It should be noted that the hydrogen generator in this embodiment can also be equipped with a heat exchanger. The heat exchanger is connected to the mixing station and the gas reactor 100 via pipelines to exchange heat between the mixed liquid and / or the crude hydrogen produced, thereby improving reaction efficiency and hydrogen yield. The hydrogen generator in this embodiment can also be used to produce hydrogen from natural gas or other hydrogen production methods that are the same as or similar to those used in methanol-water hydrogen production.
