Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1 like Figs. 1 to 4 As shown, the integrated hydrogen production and combustion device with built-in serpentine pipe high-efficiency heat exchange in this embodiment 1 includes a feeding component, a high-temperature cracking component, an ignition component, and a body 100. The feeding component includes a first pipe 400 and a second pipe 410. The inlet end of the first pipe 400 extends outside the body 100 to connect to the feeding source. The first end of the second pipe 410 is connected to the first pipe 400, and the second end of the second pipe 410 is connected to the combustion head. The outlet end of the first pipe 400 is connected to the high-temperature cracking component, and the gas outlet of the high-temperature cracking component is connected to the combustion head.

[0025] Furthermore, the high-temperature pyrolysis assembly includes an outer shell 700 and a combustion chamber 500. One end of the combustion chamber 500 extending out of the outer shell 700 is provided with a flame outlet. The combustion chamber 500 is disposed inside the outer shell 700 and directly opposite the combustion head. A serpentine pipe 510 is disposed in the inner wall of the combustion chamber 500. The serpentine pipe 510 is embedded in the combustion chamber 500, meaning it is not visible on either the inner or outer wall of the combustion chamber 500. The inlet end of the serpentine pipe 510 is connected to the first pipe 400, and the outlet end of the serpentine pipe 510 is connected to the combustion head.

[0026] The ignition assembly includes an electric spark generator 910 and a controller 900 disposed within the body 100, with the end of the electric spark generator 910 extending to the position of the burner head.

[0027] Meanwhile, a blower chamber connected to the combustion chamber 500 is defined inside the body 100. A blower is installed on the body 100 at the position corresponding to the blower chamber. At this time, a combustion chamber is defined inside the body 100 at the position corresponding to the burner head. The combustion chamber is connected to the combustion chamber 500. The fuel burned in the combustion chamber is finally ejected through the combustion chamber 500 and the flame is ejected from the flame outlet.

[0028] In use, the high-temperature pyrolysis unit, controlled by the feeding unit, can separately complete the pyrolysis of raw materials to produce hydrogen and the combustion of the produced hydrogen to release heat, eliminating the need for hydrogen storage and transportation and improving the overall system safety.

[0029] During combustion, the combustion chamber and combustion liner 500 release a large amount of heat. To prevent this heat from leaking from the outer shell 700 or being transferred to the feeding assembly, a heat insulation layer 800 is provided between the outer shell 700 and the combustion liner 500. A cavity is formed between the outer wall of the heat insulation layer 800 and the inner wall of the outer shell 700 to accommodate the first pipe 400 and the second pipe 410. The end of the outer shell 700 and the outer wall of the combustion liner 500 form a cooling outlet communicating with the cavity. In this way, the heat insulation layer not only reduces heat loss but also protects the first pipe 400 and the second pipe 410. When the blower blows air, some low-temperature gas can flow through the cavity and out through the cooling outlet, thereby cooling the heat insulation layer 800 and preventing the cavity from becoming too hot.

[0030] In this embodiment 1, the burner head is the fuel injection point and also the origin of the flame.

[0031] Specifically, the burner head includes a cylindrical base 600, within which a cavity is defined. The cavity communicates with the serpentine conduit 510 and the second conduit 410. Multiple fuel nozzles 610 are arranged on the side of the base 600 facing the combustion chamber 500. The serpentine conduit 510 can absorb more heat, allowing the raw materials within it to decompose at high temperatures. The multiple fuel nozzles 610 ensure a more uniform combustion process.

[0032] In order for the spark generator 910 to ignite the fuel more evenly during ignition, the spark generator 910 is configured to extend from the center of the base 600 to near the fuel nozzle 610.

[0033] At this time, the blower is mainly used to provide air to the combustion chamber and combustion liner 500. Specifically, the blower includes a first motor 200 and an impeller 210. The impeller 210 is rotatably disposed inside the blower cavity, the first motor 200 is disposed outside the body 100, and the body 100 is also provided with an air intake assembly that communicates with the blower cavity.

[0034] Specifically, the air intake assembly includes an air intake duct 300, an air damper is installed inside the air intake duct 300, and an actuator for controlling the air damper is installed on the air intake duct 300. The opening size of the air damper is controlled by the actuator, thereby controlling the air intake volume in the blower chamber.

[0035] Furthermore, the damper includes an upper damper 310 and a lower damper 320, which are arranged in the same vertical plane. The actuator includes a first rotating rod 311 fixedly connected to the upper damper 310 and a second rotating rod 321 fixedly connected to the lower damper 320. Both the first rotating rod 311 and the second rotating rod 321 are rotatably mounted on the air inlet duct 300. A second motor 340 for driving the first rotating rod 311 is provided on one side of the air inlet duct 300. The sides of the first rotating rod 311 and the second rotating rod 321 away from the second motor 340 are connected by a connecting rod 330.

[0036] To better perceive the situation inside the machine body 100, a wind pressure detection element 120 and a flame detection element 110 are installed at the location corresponding to the blower cavity of the machine body 100. The wind pressure detection element 120 and the flame detection element 110 can sense the wind pressure and combustion status inside the machine body 100, and can provide reference data for the combustion process to facilitate control.

[0037] To control the fuel flow, a main valve 401 is installed near the inlet of the first pipe 400, and a two-stage ignition solenoid valve 402 is installed after the first pipe 400 passes the second pipe 410. A first-stage ignition solenoid valve 411 is installed on the second pipe 410. The two-stage ignition solenoid valve 402 and the first-stage ignition solenoid valve 411 can be used to adjust and control the fuel injection sequence from the burner head, facilitating preheating of the combustion chamber 500 and switching of subsequent combustion processes.

[0038] The specific working process of the integrated hydrogen production and combustion device with built-in serpentine pipe high-efficiency heat exchange in Embodiment 1 is as follows: First, the combustion chamber 500 is purged by a blower, followed by a preheating step. The preheating step includes closing the second-stage ignition solenoid valve 402 and opening the first-stage ignition solenoid valve 411 and the main valve 401, allowing the raw materials to enter the combustion head through the second pipe 410. The raw materials here are methanol and water, with methanol accounting for 65% and water accounting for 35%. Ignition is then performed, allowing the methanol to burn and preheat the combustion chamber 500, raising its temperature to 830℃-850℃. At this point, the hydrogen production stage can begin. In the hydrogen production stage, the second pipe 410 needs to be closed, allowing methanol and water to enter the serpentine pipe 510 of the combustion chamber 500 through the first pipe 400 for high-temperature cracking. The cracked hydrogen gas is still ejected from the combustion head and is then ignited again to achieve combustion and heat supply. Both the preheating and hydrogen production stages require control of the air pressure within the blower chamber, including the degree of damper opening. The damper is opened to its maximum during scavenging and can be adjusted to the required level during combustion. Additionally, the fuel can be ethanol and water, with ethanol comprising 60% and water 40%; petroleum ether and water, with petroleum ether comprising 50% and water 50%; naphtha and water, with each comprising equal parts; or diesel and water, with each comprising equal parts.

[0039] Example 2 The integrated hydrogen production and combustion method with built-in serpentine pipe high-efficiency heat exchange in Embodiment 2 adopts the aforementioned integrated hydrogen production and combustion device with built-in serpentine pipe high-efficiency heat exchange, and specifically includes the following steps: S1. Preheating stage: Control the blower to start and purge the combustion chamber 500; close the second-stage ignition solenoid valve 402 on the first pipe 400, and simultaneously open the first-stage ignition solenoid valve 411 and the main valve 401 on the second pipe 410; allow the preheated fuel to be transported to the combustion head through the second pipe 410 and ignited by the electric spark generator 910, and burn in the combustion chamber 500; by controlling the combustion process, heat the inner wall temperature of the combustion chamber 500 to the pyrolysis preparation temperature of 830℃~850℃.

[0040] S2. Hydrogen Production and Combustion Stage: When the combustion chamber 500 reaches the pyrolysis preparation temperature, the first-stage ignition solenoid valve 411 is closed, and the second-stage ignition solenoid valve 402 is opened simultaneously. The hydrogen production feedstock is transported through the first pipeline 400 and flows into the serpentine pipe 510 in the inner wall of the combustion chamber 500. When the hydrogen production feedstock flows through the serpentine pipe 510 surrounded by high-temperature flames, it absorbs the high-temperature heat inside the combustion chamber 500 and undergoes a pyrolysis reaction to generate hydrogen. The hydrogen generated by pyrolysis is output from the outlet end of the serpentine pipe 510 to the combustion head. After mixing with air, it is ignited again in the flame channel of the combustion chamber 500 for continuous combustion and heating.

[0041] S3. Cooperative control steps: During the preheating stage and the hydrogen production and combustion stage, the controller 900 receives feedback signals from the wind pressure detection element 120 and the flame detection element 110 in real time and controls the opening degree of the blower damper.

[0042] The integrated hydrogen production and combustion device and method of the present invention, with built-in serpentine pipe for high-efficiency heat exchange, can complete the cracking of raw materials to produce hydrogen and the combustion of the produced hydrogen to release heat, eliminating the need for hydrogen storage and transportation and improving the overall system safety. The serpentine pipe can absorb more heat, allowing the raw materials within it to crack at high temperatures. Simultaneously, multiple fuel nozzles ensure a more uniform combustion process. Furthermore, the insulation layer reduces heat loss and protects the first and second pipes. The opening size of the damper is controlled by the actuator, which controls the air intake in the blower chamber. The air pressure detector and flame detector sense the air pressure and combustion status within the machine, providing reference data for combustion control. The fuel injection sequence of the burner head can be controlled by a two-stage ignition solenoid valve and a one-stage ignition solenoid valve, facilitating preheating of the combustion chamber and subsequent combustion switching.

[0043] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.

Preheating stage: The blower is started to purge the combustion chamber (500); the second-stage solenoid valve (402) on the first pipe (400) is closed, while the first-stage solenoid valve (411) on the second pipe (410) and the main valve (401) are opened; the preheated fuel is transported to the combustion head through the second pipe (410) and ignited by the electric spark generator (910) and burned in the combustion chamber (500); by controlling the combustion process, the inner wall temperature of the combustion chamber (500) is heated to the pyrolysis preparation temperature of 830℃~850℃; S2, Hydrogen Production and Combustion Stage: When the combustion chamber (500) reaches the pyrolysis preparation temperature, the first-stage ignition solenoid valve (411) is closed, and the second-stage ignition solenoid valve (402) is opened simultaneously; the hydrogen production raw material is transported through the first pipeline (400) and flows into the serpentine pipe (510) in the inner wall of the combustion chamber (500); when the hydrogen production raw material flows through the serpentine pipe (510) surrounded by high-temperature flames, it absorbs the high-temperature heat in the combustion chamber (500) and undergoes a pyrolysis reaction to generate hydrogen; the hydrogen generated by pyrolysis is output from the outlet end of the serpentine pipe (510) to the combustion head, mixed with air, and then ignited again in the flame channel of the combustion chamber (500) for continuous combustion and heating; S3. Cooperative control steps: During the preheating stage and the hydrogen production and combustion stage, the controller (900) receives feedback signals from the wind pressure detection device (120) and the flame detection device (110) in real time and controls the opening degree of the blower damper.
