[0032] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Please refer to Figure 1-Figure 10 The embodiment of the utility model provides a photothermal coupled biomass energy synthesis gas production device, including a heat absorber 1 with a heat transfer fluid inside, and the heat absorber 1 is surrounded by a mirror array 2 in a circumferential direction. The solar energy is reflected by the mirror array 2 to heat the heat transfer fluid in the heat absorber 1, and the heat transfer fluid is stored in a hot fluid storage device 21. When the device is running, the heat transfer fluid enters the gasifier 5 through a conduit to preheat the biomass, and promotes the gasification of the biomass to produce synthesis gas. The outlet flow is cooled by the cooling device 4 and then enters the cold fluid storage device 3, and high-temperature water vapor is generated for biomass gasification. The upper end of the gasifier 5 is rotatably provided with a hollow tube 8, and the lower end of the hollow tube 8 is rotatably provided with a diverter. A plurality of steam injection assemblies are installed on the diverter. The high-temperature steam in the steam injection assembly preheats the material, and the crude synthesis gas obtained by the reaction in the gasifier 5 is washed and cooled by a washing tower 6.

[0034] Among them, the diverter includes a connecting pipe 9 connected to the steam outlet of the hollow tube 8. There are multiple connecting pipes 9, and the steam outlets of the multiple connecting pipes 9 are all connected to the annular tube 10. At the same time, the steam inlet at the upper end of the hollow tube 8 is rotatably connected to the steam pipe 7. The steam inlet of the steam pipe 7 is connected to the steam outlet of the hot fluid storage device 21, so that steam can be introduced into the gasifier 5. At the same time, when the hollow tube 8 is rotated, it does not affect the transmission of steam.

[0035] The steam injection assembly includes a nozzle 11 connected to the annular tube 10 . The length of the nozzle 11 is adapted to the internal size of the gasifier 5 and can cover the material inside. A plurality of nozzles 12 are opened on one side of the nozzle 11 , and the incoming steam is ejected through the nozzles 12 .

[0036] In order to prevent the material from clogging the nozzle 12, a fixing sleeve 14 is fixed at both ends of the nozzle 11 by bolts, the sides of the two fixing sleeves 14 are connected by a vertical plate 13, a positioning sleeve 15 is installed on one side of the fixing sleeve 14, and a dustproof net 16 is fixed between the two positioning sleeves 15. The dustproof net 16 is used to isolate the material without affecting the output of steam.

[0037] In addition, an annular groove 18 is provided on the lower side of the positioning sleeve 15, and clamping plates 22 are provided on the upper and lower sides of the dustproof net 16. The clamping plates 22 are engaged with the annular groove 18 to facilitate the disassembly and assembly of the dustproof net 16, and further facilitate the cleaning of the dustproof net 16.

[0038] Furthermore, an arc plate 17 is provided on one side of the dustproof net 16. The arc plate 17 is provided with a plurality of mesh holes. The arc plate 17 strengthens the isolation of the material. Meanwhile, the arc plate 17 has an arc-shaped structure, which can push the material and further prevent the material from being blocked.

[0039] When steam is input, the hollow tube 8 can rotate with the annular tube 10 and the nozzle 11 to realize the comprehensive transportation of steam. Therefore, in order to make the hollow tube 8 rotate automatically, a gear 19 is rotatably provided on the outer side of the hollow tube 8, and a gear 20 is rotatably provided on the upper side of the gasifier 5. The gear 20 is driven by a motor. When the gear 20 rotates, the gear 19 and the gear 20 are meshed to make the gear 19 rotate with the hollow tube 8.

[0040] In summary, the photothermal coupled biomass energy synthesis gas production device of the embodiment of the utility model has the following working principle: the meshing of gear 19 and gear 2 20 causes the hollow tube 8 to rotate with the connecting tube 9 and the annular tube 10, and causes the annular tube 10 to rotate with the nozzle 11. When the steam enters, the comprehensive steam transportation is realized with the rotation of the nozzle 11. At the same time, the dustproof net 16 is used to block the nozzle 12 on the nozzle 11 to prevent the material from entering the nozzle 12. At the same time, the arc plate 17 with mesh is used to strengthen the shielding of the material. When the nozzle 11 rotates, the arc plate 17 pushes the material, effectively preventing the material from entering the nozzle 12.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
