[0028] See also Figure 1-Figure 2 The reactor is usually made of high temperature and pressure resistant materials, such as stainless steel or alloy steel. The reactor is designed with a catalyst bed inside, which is used to promote the pyrolysis reaction of water and natural gas. Under high temperature, the hydrocarbons in water and natural gas will be decomposed into hydrogen and other by-products, such as carbon monoxide and carbon dioxide.
[0029] However, when in use, the conventional catalytic pyrolysis hydrogen production reactor set therein needs to stop the catalytic reaction because the floating carbon 9 rises to a certain height, and the floating carbon 9 and the catalytic salt 8 cannot be discharged. Based on this, the present application provides a novel overflow device for a catalytic pyrolysis hydrogen production reactor, comprising a reactor cylinder 1 for catalytic pyrolysis hydrogen production, a heater 2 installed on the outside of the reactor cylinder 1, a feeding assembly 13 arranged on the top of the reactor cylinder 1, and a feeding barrel 12 combined with the feeding assembly 13;
[0030] Two through holes are provided at the positions near the center of the outer wall of the reactor cylinder 1, and a conduit 7 is sealed and fixed thereto. A collecting cylinder 3 is provided at the bottom of the conduit 7 for collecting the target object guided out through the conduit 7.
[0031] The inner side of the reactor cylinder 1 is filled with catalyst, and a layer of catalytic salt 8 is loaded on the top of the catalyst. The catalytic salt 8 is located below the feeding cylinder, and floating carbon 9 is precipitated above it. A heating device is also provided on the outer side of the reactor cylinder 1 to melt the catalytic salt 8 and take away the floating carbon 9.
[0032] The reactor cylinder 1 is filled with a catalyst, a layer of catalytic salt 8 is placed on the top of the catalyst, the feeding cylinder is located below the catalytic salt 8, and floating carbon 9 is generated above the catalytic salt 8. In order to solve the problem of discharging floating carbon 9 and catalytic salt 8, the device opens two through holes near the center on both sides of the outer wall of the reactor cylinder 1, and installs a sealed and fixed conduit 7. A collecting cylinder 3 is set at the bottom of the conduit 7 to collect the target discharged through the conduit 7.
[0033] At the same time, the outer side of the reactor cylinder 1 is also equipped with a heating device for melting the catalytic salt 8, thereby removing the floating carbon 9. The heating device can provide sufficient heat to the catalytic salt 8 to melt it and remove the floating carbon 9 to maintain the effective activity of the catalyst.
[0034] When in use, the feeding assembly 13 is combined with the feeding barrel 12 to realize automatic addition of reactants, and through the combination of the conduit 7 and the collecting cylinder 3, the floating carbon 9 and the catalytic salt 8 are effectively discharged, thereby maintaining the continuous progress and stability of the reaction.
[0035] By opening through holes on both sides of the outer wall of the reactor cylinder 1 and installing the conduit 7, the floating carbon 9 and the catalytic salt 8 can be effectively discharged under the premise of ensuring the sealing. This can prevent the floating carbon 9 and the catalytic salt 8 from accumulating in the reactor, resulting in a decrease in reaction efficiency or equipment failure.
[0036] The collecting cylinder 3 disposed at the bottom of the conduit 7 is used to collect the target objects discharged through the conduit 7, such as floating carbon 9 and catalytic salt 8. The design of the collecting cylinder 3 enables the target objects to be collected and processed in a centralized manner, thereby avoiding the diffusion of the target objects and pollution to the environment.
[0037] The catalytic salt 8 is melted by the external heating device, which can effectively remove the generated floating carbon 9. This method can remove the floating carbon 9 in time, maintain the stability and efficiency of the catalytic reaction, and extend the service life of the catalyst.

[0039] A collecting tube flange 5 is provided on the top of the collecting tube 3, and an overflow pipe flange 4 is connected to the top of the collecting tube flange 5 via bolts 6 for connecting with a conduit 7 to form an overflow passage.
[0040] The feeding barrel 12 includes a barrel body 121 , and the top of the barrel body 121 is connected to the feeding assembly 13 through a pipeline for controlling the amount of feeding in the later reaction.
[0041] A sealing groove 122 is upwardly provided at the bottom of the barrel body 121 , and a sealing plate 128 is sealed at the sealing groove 122 for sealing the barrel body 121 .
[0042] A drainage pipe 1210 is provided in the middle of the bottom of the closing plate 128 . The drainage pipe 1210 is connected to the barrel body 121 and extends below the liquid surface of the catalytic salt 8 .
[0043] A collecting tube flange 5 is provided on the top of the collecting tube 3, which is connected to the overflow pipe flange 4 by bolts 6 and is used to connect to the conduit 7 to form an overflow passage. In this way, the floating carbon 9 and the catalytic salt 8 can be smoothly discharged from the reactor through the conduit 7 and enter the overflow pipe, thereby realizing overflow treatment.
[0044] In addition, the feeding barrel 12 in the device is composed of a barrel body 121, and the top of the barrel body 121 is connected to the feeding assembly 13 through a pipeline. This connection method can control the amount of feeding in the later reaction and ensure accurate and stable material addition during the reaction.
[0045] In order to ensure the sealing of the feeding barrel 12, a sealing groove 122 is provided upwardly at the bottom of the barrel body 121, and a closing plate 128 is installed at the sealing groove 122. In this way, the closing plate 128 can effectively close the feeding barrel 12 to prevent material leakage and gas leakage during the reaction process.
[0046] A drainage pipe 1210 is provided at the middle of the bottom of the closing plate 128, and the pipe is connected to the barrel 121 and extends below the liquid level of the catalytic salt 8. The drainage pipe 1210 plays a role of guiding and diverting, and can guide the overflowing catalytic salt 8 to the correct position to avoid overflow and waste. In this way, the liquid level of the catalytic salt 8 can be kept stable to ensure the normal progress of the reaction process.
[0047] See also Figure 3 , Figure 4 as well as Figure 5 One or more slide grooves 124 are arranged on the outside of the drainage pipe 1210, and a guide block 123 is slidably connected to the inside of the slide groove 124. A groove is opened in the middle of the guide block 123 to form an "I"-shaped disc, and the disc on the side close to the catalytic salt 8 is also opened with filter holes 127 arranged at equal distances for guiding the discharge of the floating carbon 9.
[0048] A combination groove 126 is provided at the bottom of the drainage tube 1210, and a discharge plate 125 is connected through the combination groove 126.

A groove is provided in the middle of the guide block 123 to form an "I"-shaped disc. In particular, the disc on the side close to the catalytic salt 8 is also provided with filter holes 127 arranged at equal distances to guide the discharge of the floating carbon 9. Such a design helps to smoothly discharge the floating carbon 9 generated by the catalytic reaction, and filter out finer particles through the filter holes 127, ensuring that the floating carbon 9 is guided while keeping the medium clean and stable.
[0050] In addition, a combination groove 126 is provided at the bottom of the drainage tube 1210, and the discharge plate 125 is connected through the combination groove 126. A convex ring 129 adapted to the combination groove 126 is provided on one side of the discharge plate 125 for fixing the discharge plate 125. A discharge hole 1211 for material discharge is provided at the bottom of the discharge plate 125 for assisting the discharge of materials. This design can realize the effective discharge of materials, so that the products in the reaction process can be discharged smoothly, reduce the residue in the reactor, and maintain the continuity and stability of the reaction process.
[0051] The working process is:
[0052] See also Figure 1 , load the designed catalyst into the reactor cylinder 1, check the sealing of the combined connection between the conduit 7 and the collecting cylinder 3, close the door of the feeding device to check the sealing, and exhaust the air in the reactor by filling and discharging nitrogen using the volume expansion method;
[0053] Close the isolation valve and heater 2, observe the temperature and pressure gauge to determine the reaction status, introduce the reaction gas through the gas inlet 10, and use the gas outlet 11 to adjust the pressure;
[0054] The catalytic reaction in the reactor continues to proceed, and floating carbon 9 is produced at the upper end of the catalytic salt 8 melt. When the liquid level of the catalytic salt 8 melt is higher than the overflow port height, the catalytic salt 8 flows into the collecting tube 3 through the conduit 7. The floating carbon 9 is brought into the collecting tube 3 during the overflow of the catalytic salt 8 melt.
[0055] When the catalytic salt 8 melt does not overflow, the isolation valve is opened, and the feeding barrel 12 in the figure is lowered to the limit bottom, and the cotton rope wrapped around it is burned off at high temperature. The catalyst is opened, and the catalytic salt 8 is added to the reactor. The liquid level rises and the overflow port continues to have catalytic salt 8 melt to discharge the floating carbon 9. The floating carbon 9 in the reactor is controlled and the catalytic reaction in the reactor continues;
[0056] Or as attached Figure 2 As shown, by utilizing automated control components, such as a liquid level valve, etc., with the support of sensor data, the material is discharged through the drainage tube 1210 to achieve continuous feeding to meet the needs of the reaction.
