Description

Technical Field

[0001] This invention relates to the field of chemical equipment technology, and more specifically, to a hydrogen-rich gas generator. Background Technology

[0002] Hydrogen energy, recognized as a clean energy source, is emerging as a low-carbon and zero-carbon energy source in today's society. As a new energy fuel, hydrogen exhibits a vast and potentially huge market. How to plan for and technologically prepare for this inevitable development is a matter of paramount importance. Choosing advanced technologies and rational methods to produce and apply hydrogen to achieve maximum economic and environmental benefits is the future development trend.

[0003] Currently, methanol is widely used to produce hydrogen. Methanol-to-hydrogen production refers to the process where, under certain temperature and pressure conditions, a methanol solution is used as a raw material. The methanol solution is heated to produce methanol vapor, which then undergoes a conversion reaction under the action of a hydrogen-producing catalyst, ultimately producing hydrogen. In existing technologies, the vapor production process mainly uses combustion catalysis to heat the methanol solution, ultimately yielding vapor. However, methanol solutions often contain both gaseous and liquid methanol. Therefore, when heating the methanol solution using combustion catalysis, the methanol solution is heated unevenly, and the heat from the combustion of the exhaust gas cannot be fully utilized, ultimately reducing the efficiency of hydrogen production. Summary of the Invention

[0004] This invention can solve the technical problem that uneven heating of the methanol solution during the methanol-to-hydrogen process leads to heat waste and ultimately affects the hydrogen production efficiency.

[0005] To address the aforementioned problems, this invention provides a hydrogen-rich gas generating device, comprising: a steam generator, a superheater, and a hydrogen reactor. The steam generator is used to generate steam, the superheater is used to heat the steam, and the hydrogen reactor is used to generate hydrogen. The steam generator includes: a generator body with a steam material receiving cavity inside for storing steam material; and a steam material pipeline located outside the generator body and connected to the steam material receiving cavity for conveying steam material into the cavity. The steam material pipeline includes: a steam material conveying pipe and a gas-liquid separation pipe. The steam material conveying pipe is connected to a steam material conveying device, and the gas-liquid separation pipe is connected between the steam material conveying pipe and the steam material receiving cavity. The steam material is conveyed from the steam material conveying device to the gas-liquid separation pipe via the steam material conveying pipe, and the gas-liquid separation pipe can separate the steam material into gas and liquid components.

[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting up a gas-liquid separation pipe, gas-liquid separation of the vapor material is achieved, allowing the gaseous and liquid materials in the vapor material to be transported to the vapor material receiving cavity through different pipes. It can be understood that since the density of the gaseous material is less than that of the liquid material, the gaseous material will be on top and the liquid material will be on the bottom after the vapor material is transported to the vapor material receiving cavity. When the vapor material after gas-liquid separation is heated by combustion catalysis, both the liquid and gaseous materials can fully absorb the heat, thereby reducing heat loss and ultimately improving the efficiency of hydrogen production.

[0007] Furthermore, in this invention, the gas-liquid separation pipe includes: a connecting pipe connected to a vapor material conveying pipe; a first pipe, one end of which is connected to the connecting pipe and the other end of which is connected to a vapor material receiving cavity; and a second pipe, one end of which is connected to the connecting pipe and the other end of which is connected to the vapor material receiving cavity; wherein, the liquid vapor material after gas-liquid separation is conveyed to the vapor material receiving cavity by the first pipe; and the gaseous vapor material after gas-liquid separation is conveyed to the vapor material receiving cavity by the second pipe.

[0008] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: After the steam material is transported from the steam material conveying pipe to the connecting pipe, the connecting pipe can transport liquid steam material to the first pipe and gaseous steam material to the second pipe, realizing gas-liquid separation in the steam material. After the gas-liquid separation, the steam material can fully absorb heat after being transported to the steam material receiving cavity, thereby improving the efficiency of hydrogen production in the hydrogen-rich gas generator.

[0009] Furthermore, in this invention, the second pipe is arranged parallel to the first pipe, and the second pipe is located above the first pipe in the vertical direction.

[0010] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the parallel arrangement of the first and second pipes achieves the purpose of stably delivering steam material to the steam material receiving cavity, and further improves the efficiency of steam generator in producing steam.

[0011] Furthermore, in this invention, the generator body is also provided with an exhaust gas containment chamber, a steam containment chamber, and an waste gas containment chamber; wherein the exhaust gas containment chamber, the steam material containment chamber, the steam containment chamber, and the waste gas containment chamber are arranged sequentially.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: After exhaust gas is introduced into the exhaust gas chamber, it can flow into the steam material receiving chamber. The heat released after the reaction in the steam material receiving chamber is absorbed by the steam material in the chamber, ultimately achieving the purpose of steam preparation. It can be understood that as the exhaust gas continues to burn, the temperature of the exhaust gas will decrease. After complete combustion, it will flow into the exhaust gas receiving chamber and eventually be discharged. In this process, the heat of the exhaust gas is fully utilized, further improving the efficiency of steam preparation.

[0013] Furthermore, the present invention also includes: an exhaust gas inlet pipe, which is disposed on the generator body and connected to the exhaust gas receiving cavity; a first steam outlet pipe, which is disposed on the generator body and connected to the steam receiving cavity; and an exhaust gas outlet pipe, which is disposed on the generator body and connected to the exhaust gas receiving cavity.

[0014] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the exhaust gas inlet pipe is designed to deliver exhaust gas into the exhaust gas containment chamber, and after the exhaust gas is completely combusted, it can be discharged from the exhaust gas outlet pipe. In this process, the heat of the exhaust gas combustion is effectively utilized, and the exhaust gas discharged after combustion also greatly reduces the harm to the environment.

[0015] Furthermore, in this invention, the steam generator also includes a third pipe, which is disposed in the steam material receiving chamber and the steam receiving chamber, and the two ends of the third pipe are respectively connected to the waste gas receiving chamber and the tail gas receiving chamber; and the third pipe is filled with a combustion catalyst.

[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: after the exhaust gas enters the third pipe through the exhaust gas containment chamber, it can react with the combustion catalyst to generate heat, thereby enhancing the efficiency of the third pipe.

[0017] Furthermore, in this invention, the steam generator further includes: an expansion joint disposed on the generator body near the steam receiving chamber; and / or, an expansion joint disposed on a third pipe.

[0018] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the expansion joint can prevent the generator body from deforming during the heating process, thereby effectively protecting the generator body and steam generator and further improving its service life.

[0019] Furthermore, in this invention, the superheater includes: a superheater body, the superheater body having a superheated cavity inside; a first steam inlet pipe, one end of which is connected to a first steam outlet pipe and the other end of which is connected to the superheated cavity; and a second steam outlet pipe, which is connected to the superheated cavity.

[0020] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting up a superheater, the steam can be further heated, thereby ensuring the efficiency of steam-to-hydrogen production. It is understandable that when steam is transported through pipelines, the heat of the steam will gradually decrease, which will affect the hydrogen production. By setting up a superheater to further heat the steam, the temperature required for hydrogen production is ensured, thereby further improving the hydrogen production efficiency.

[0021] Furthermore, in this invention, the hydrogen reactor includes: a reactor body, the reactor body having a hydrogen containment chamber inside; a second vapor inlet pipe, one end of which is connected to a second vapor outlet pipe and the other end of which is connected to the hydrogen containment chamber; and a hydrogen outlet pipe, which is connected to the hydrogen containment chamber; wherein, the hydrogen containment chamber is filled with a hydrogen production catalyst.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: after the steam is introduced into the reactor body, it can react with the hydrogen production catalyst filled in the hydrogen storage chamber at a certain temperature, and finally produce hydrogen. The reactor body is designed to achieve the purpose of producing hydrogen, and at the same time improves the hydrogen production efficiency.

[0023] Furthermore, the present invention also includes: a first heating element disposed on the generator body for heating the vapor material containing cavity; a second heating element disposed on the superheater body for heating the superheated cavity; and a third heating element disposed on the reactor body for heating the hydrogen containing cavity.

[0024] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the arrangement of the first heating element, the second heating element, and the third heating element improves the efficiency of steam and hydrogen production.

[0025] In summary, by adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] i) By setting up a gas-liquid separation pipe, gas-liquid separation of the vapor material is achieved, which allows the gaseous and liquid materials in the vapor material to be transported to the vapor material receiving cavity through different pipes. It can be understood that since the density of the gaseous material is less than that of the liquid material, the gaseous material will be on top and the liquid material will be on the bottom after the vapor material is transported to the vapor material receiving cavity. When the vapor material after gas-liquid separation is heated by combustion catalysis, the liquid and gaseous materials can fully absorb the heat, thereby reducing heat loss and ultimately improving the efficiency of hydrogen production.

[0027] ii) After the vapor material is transported to the connecting pipe by the vapor material conveying pipe, the connecting pipe can transport liquid vapor material to the first pipe and gaseous vapor material to the second pipe, realizing gas-liquid separation in the vapor material. After the vapor material is transported to the vapor material receiving cavity after gas-liquid separation, it can fully absorb heat, thereby improving the efficiency of hydrogen production in the hydrogen-rich gas generator.

[0028] iii) The expansion joint can prevent the generator body from deforming during heating, thus effectively protecting the generator body and steam generator and further improving service life. Attached image description:

Detailed Implementation

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The hydrogen-rich gas generating device 100 includes, for example, a steam generator 10, a superheater 20, and a hydrogen reactor 30. The steam generator 10 is used to generate steam, and the steam generated by the steam generator 10 is sent to the superheater 20. The superheater 20 is used to heat the steam generated by the steam generator 10. The steam after being further heated by the superheater 20 is sent to the hydrogen reactor 30, thereby achieving the purpose of hydrogen production.

[0045] Specifically, in the hydrogen-rich gas generating device 100, a vapor material is first introduced into a vapor generator 10. The vapor material evaporates in the vapor generator 10 to generate vapor. The vapor generated by the vapor generator 10 is then introduced into a superheater 20. The superheater 20 is equipped with a heating device to further heat the vapor. The vapor, after being further heated by the superheater 20, is then transported to a hydrogen reactor 30. The hydrogen reactor 30 stores a hydrogen-producing catalyst. After being heated by the superheater 20, the vapor in the hydrogen reactor 30 reacts with the hydrogen-producing catalyst to ultimately produce hydrogen. In this invention, the vapor material used can be water, methanol, a mixture of methanol and water, or other alcohols or mixtures of other alcohols and water.

(Not shown in the figure) The combustion catalyst can react with the exhaust gas in the exhaust gas receiving chamber 131 at a certain temperature. Under the action of the catalyst, the exhaust gas can be combusted and generate a large amount of heat. The released heat can further heat the steam material outside the third pipe 18, thereby causing the steam material to generate steam. At the same time, after the exhaust gas reacts with the combustion catalyst in the third pipe 18, it will become waste gas. The waste gas will flow upward into the waste gas receiving chamber 174 and finally be discharged to the outside from the waste gas output pipe 16.

The steam generator 10 prepares steam as follows: firstly, steam material is introduced into the steam material receiving chamber 171 through the steam material pipe 15, and then the exhaust gas is introduced through the exhaust gas input pipe 1. The exhaust gas is transported to the exhaust gas receiving chamber 131, and then further transported from the exhaust gas receiving chamber 131 to the third pipe 18. The exhaust gas reacts with the combustion catalyst in the third pipe 18, thereby releasing a large amount of heat. The heat generated by the combustion of the exhaust gas then heats the steam material, thereby generating steam. The steam is then transported from the steam material receiving chamber 171 to the steam receiving chamber 172, and finally transported to the superheater 20 through the first steam output pipe 173. At the same time, the exhaust gas after combustion is transported from the third pipe 18 to the waste gas receiving chamber 174, and finally discharged to the outside through the waste gas output pipe 16.

The gas part of the steam material flows upward into the second pipe 154, and the liquid part of the steam material flows downward into the first pipe 153. Finally, the liquid in the steam material flows into the steam material receiving cavity 171 through the lower first pipe 153, and at the same time, the liquid in the steam material flows into the steam material receiving cavity 171 through the upper second pipe 154.
