Two front-to-back symmetrical air inlets 55 are arranged at the bottom of the reforming cavity 5, and the gas flows into it for reaction; the top of the reforming cavity 5 is provided with a product outlet 54.

[0044] The intelligent fixed-point heating resistance coil 51 is composed of a plurality of resistance heating units 511 connected by pure nickel high-temperature wires. Each resistance heating unit 511 is composed of a resistor 5111 with a hollow cylindrical structure and an intelligent heating controller 5112 located inside the resistor 5111. The intelligent heating controller 5112 is provided with a temperature sensor and a control switch. The resistance heating unit 511 is connected to the PLC system.

[0045] The outer wall of the reforming chamber 5 is wrapped with a preheating outer layer 4; the side wall of the preheating outer layer 4 is a first quartz window 41, which is made of quartz with strong light transmittance; two openings 43 are symmetrically arranged on the top of the preheating outer layer 4, and two sets of left-right symmetrical curved pipelines 42 are distributed inside the preheating outer layer 4, and temperature sensors are arranged in the curved pipelines 42; the top of the curved pipeline 42 is connected to the corresponding opening 43, and the end of the curved pipeline 42 is connected to the air inlet 55 at the bottom of the reforming chamber 5.

[0047] The concentrating solar panel 61 is a double-layer structure, the upper layer is a plurality of rows of concentrating reflectors 611 arranged in sequence, and the lower layer is a solar panel 614; each row of concentrating reflectors 611 is composed of a plurality of concentrating reflectors 611 connected in sequence, and the rows are connected by nickel-based high-temperature synthetic wires; two adjacent rows of concentrating reflectors 611 are connected by springs 612, and the springs 612 are made of nickel-based high-temperature synthetic wires; an electric cut-off telescopic rod 613 is provided at the bottom of the plurality of rows of concentrating reflectors 611, the base of the electric cut-off telescopic rod 613 is fixed to one end of the plurality of rows of concentrating reflectors 611, and the extended end of the electric cut-off telescopic rod 613 is connected to the electric cut-off telescopic rod 613 away from the electric cut-off telescopic rod 613.

[0049] This embodiment proposes a methane dry reforming photoelectric coupling reactor that efficiently utilizes solar energy. The working principle is:

[0050] Methane and carbon dioxide are introduced from the raw material inlet 32 ​​in a volume ratio of 1:1, enter the inner tube of the serpentine sleeve 31, and then enter the curved pipeline 42 of the preheating outer layer 4 through two symmetrical openings 43 on the preheating outer layer 4. Multiple rows of focusing reflectors 611 inject light energy into the curved pipeline 42 through the first quartz window 41, which is used to preheat and heat the raw gas inside the curved pipeline 42; the heated raw gas enters the reforming chamber 5 through the air inlet 55 for methane dry reforming reaction, and the high-temperature synthesis gas produced by the reaction flows into the outer tube of the serpentine sleeve 31 through the product outlet 54, thereby preliminarily preheating the raw gas in the inner tube of the serpentine sleeve 31; the high-temperature synthesis gas after heat exchange is discharged through the product outlet 33. While preheating the raw gas in the curved pipeline 42, the temperature of the reforming chamber 5 is gradually increased under the focusing effect of the focusing heat collecting reflector 7 and the second quartz window 53, and the temperature of the catalyst environment in the reforming chamber 5 is more uniform.

[0051] Due to the shortcomings of uneven sunlight and uncontrollable sunlight, an intelligent fixed-point heating resistor coil 51 is also provided in the reforming chamber 5. Each resistance heating unit 511 is provided with an intelligent heating controller 5112. The intelligent heating controller 5112 has a temperature sensor inside and is connected to the PLC system. The resistance heating unit 511 at each part of the reforming chamber 5 is set with a reaction temperature. When the actual temperature of a point in the reforming chamber 5 is lower than the set reaction temperature, the resistance heating unit 511 at that point is powered on to generate heat until the temperature at that point reaches the set value and stops heating. Since each individual resistance heating unit 511 has an independent control structure, each resistance heating unit 511 can carry out heating work alone or work in coordination with each other; the entire heating system has temperature control flexibility, realizes refined control of the temperature in the reforming chamber 5, meets diverse heating requirements, and enables the methane dry reforming reaction to proceed efficiently and stably.

[0052] When the temperature sensor in the curved pipeline 42 sends a signal that the raw gas preheating temperature reaches the preset temperature threshold, the PLC system controls the electric telescopic rod 613 to retract, so that the multiple rows of focusing reflectors 611 are folded to expose the lower solar panels 614; the solar panels 614 are connected to the power storage element 81 to convert the solar energy absorbed by the solar panels 614 into electrical energy for storage. The power storage element 81 is connected to all electrical devices in the device through lines to provide electrical energy for these electrical devices.
