Description

Technical Field

[0001] The present invention relates to the technical field of heat storage and concentrating reaction, and specifically relates to a heat storage and concentrating reaction device for producing syngas and carbon with negative carbon emissions from methane and carbon dioxide. Background Art

[0002] As disclosed in a Chinese patent with the publication number CN214990266U, it discloses a system for converting methane and carbon dioxide into syngas using solar energy, including a solar methane dry reforming subsystem, a photovoltaic power generation subsystem, an energy storage subsystem, and a gas separation subsystem; the solar methane dry reforming subsystem includes a solar concentrator and a photothermal reforming reactor. The photothermal reforming reactor includes a hemispherical reaction tube filled with a catalyst inside. A thermocouple is arranged on the inner side wall surface of the reaction tube, and a horn-shaped light channel is arranged at the upper end of the reaction tube. The upper opening of the horn shape is sealed by a convex lens; both the reaction tube and the light channel are coated with a heat insulation layer on the outside, and an inlet pipe for the raw material gas is arranged between the heat insulation layer and the light channel.

[0003] However, the above solution has the following deficiencies: In the above patent, sunlight is guided to the position of the convex lens through a solar concentrator, and the sunlight is concentrated on the surface of the reactor through the convex lens to realize the conversion and utilization of gas. However, when used in a low-temperature environment, frost will appear on the surface of the convex lens and the surface of the concentrator. At this time, the concentrator cannot well guide the sunlight to the surface of the convex lens, and at the same time, due to frosting, the convex lens cannot well converge the light to the surface of the reaction tube. Moreover, when the external environment is in a snowing state, snow will accumulate on the surface of the concentrator. At this time, the operator needs to clean the snow before the concentrator can guide the sunlight. Therefore, we introduce a heat storage and concentrating reaction device for producing syngas and carbon with negative carbon emissions from methane and carbon dioxide. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0024] Embodiment 1:

[0025] A heat storage and concentrating reaction device for producing syngas and carbon with negative carbon emissions from methane and carbon dioxide includes a bottom plate 1. Reflective baffles 16 are provided around the upper end of the bottom plate 1. Reflective coatings are provided on the opposite surfaces of several reflective baffles 16 and the upper end of the bottom plate 1. The reflective strip coating is a stainless steel coating. The lower ends of several reflective baffles 16 are fixedly connected to gear rollers 5. The gear rollers 5 are movably connected in a connection cavity 18. The connection cavity 18 is opened at the upper end of the bottom plate 1. The gear rollers 5 are engaged with a toothed plate 32. The toothed plate 32 is fixedly connected to an L-shaped connecting plate 7. The L-shaped connecting plate 7 is movably connected in the connection cavity 18. The upper and lower ends of the L-shaped connecting plate 7 extend into the external environment. During the movement of the L-shaped connecting plate 7, the toothed plate 32 will move synchronously. Since the toothed plate 32 is engaged with the gear roller 5, during the rotation of the gear roller 5, the reflective baffles 16 will move and unfold;

[0026] The upper end of the L-shaped connecting plate 7 is connected to a solar thermochemical reforming reaction mechanism. The solar thermochemical reforming reaction mechanism is fixedly connected to the lower end of the top plate 9. The solar thermochemical reforming reaction mechanism includes a heat insulation seat 14. The upper end of the L-shaped connecting plate 7 is fixedly connected to the lower end of the heat insulation seat 14. The heat insulation seat 14 is fixedly connected inside the lower end of the top plate 9. A light channel 23 is opened at the lower end of the heat insulation seat 14. A convex lens 24 is fixedly connected to the lower end of the light channel 23. A hemispherical reaction tube 21 is fixedly connected in the light channel 23. A catalyst 11 is contained in the hemispherical reaction tube 21. A thermocouple 22 is fixedly connected to the outside of the hemispherical reaction tube 21. The thermocouple 22 is connected to a wire 13. The upper end of the wire 13 extends into the external environment. When the external environment is cloudy, at this time, the thermocouple 22 can be controlled through the wire 13 to heat the hemispherical reaction tube 21, so that the catalyst 11 reacts with the raw material gas;

[0027] There are two connecting pipes 10 fixedly connected inside the heat insulation seat 14. One end of the connecting pipe 10 extends into the optical channel 23 and is connected to the hemispherical reaction tube 21, and the other end extends into the external environment. The upper end of the hemispherical reaction tube 21 is fixedly connected with an air outlet pipe 12, and the upper end of the air outlet pipe 12 extends into the external environment. When sunlight shines on the surfaces of the reflective baffle 16 and the bottom plate 1, the sunlight will be reflected to the position of the convex lens 24 at this time. The sunlight entering the convex lens 24 is concentrated and shines on the surface of the hemispherical reaction tube 21. The raw material gas enters the hemispherical reaction tube 21 through the left connecting pipe 10 and reacts with the catalyst 11. The mixed gas generated after the reaction enters the external gas separation device through the air outlet pipe 12. The synthesis gas hydrogen / carbon monoxide in the mixed gas is separated by the gas separation device, and the unreacted raw material gas methane / carbon dioxide is re-entered into the hemispherical reaction tube 21 through the right connecting pipe 10 for reaction again. The gas separation device can be a pressure swing adsorption separation device produced by Dalian Keteli Catalyst Engineering Technology Co., Ltd.;

[0028] One side of the L-shaped connecting plate 7 is fixedly connected with a connecting plate 2, and the connecting plate 2 is connected to the lifting transmission mechanism. The lifting transmission mechanism is arranged inside the bottom plate 1. A groove 29 is opened at the upper end of the reflective baffle 16, and a first sealing mechanism is arranged at the lower end of the top plate 9. The lower end of the first sealing mechanism is clamped in the groove 29. When several reflective baffles 16 change from an inclined state to an upright state, the first sealing mechanism will be clamped into the groove 29 at this time to seal the upper sides of several reflective baffles 16;

[0029] A second sealing mechanism is arranged inside the reflective baffle 16. When the reflective baffle 16 rises, the second sealing mechanism seals between the two reflective baffles 16. When the reflective baffle 16 unfolds, the second sealing mechanism cancels the seal between the two reflective baffles 16. Triangular rubber strips 31 are fixedly connected to both ends of the reflective baffle 16, and an installation base 20 is fixedly connected to the lower end of the bottom plate 1. The installation base 20 is connected to the bracket installed on the ground, so that the bottom plate 1 is arranged in an inclined state facing the sun.

[0030] Example 2:

[0031] On the basis of Embodiment 1, in order to ensure that the T-shaped sealing rod 30 does not obstruct the reflective baffle 16 during the unfolding process of the reflective baffle 16, the lifting transmission mechanism includes a transmission motor 19 fixedly connected to the inside of the lower end of the bottom plate 1. The output end of the transmission motor 19 is fixedly connected to a transmission gear 3. A lead screw 6 is screwed inside the connecting plate 2. The lead screw 6 is movably connected to the connecting cavity 18. The lower end of the lead screw 6 extends into the external environment and is fixedly connected to a connecting gear 4. The connecting gear 4 meshes with the transmission gear 3. When the transmission motor 19 is turned on to drive the transmission gear 3 to rotate, the transmission gear 3 rotates to drive the four connecting gears 4 meshing with it to start rotating. Since the connecting gear 4 is connected to the lead screw 6, during the rotation of the connecting gear 4, the lead screw 6 will be driven to start rotating, and the rotation of the lead screw 6 drives the connecting plate 2 to move upward;

[0032] The first sealing mechanism includes a T-shaped connecting ring 27 slidably connected to the annular cavity 8 opened inside the lower end of the top plate 9. The lower end of the T-shaped connecting ring 27 extends into the external environment and is fixedly connected to a rubber sealing ring 25. The rubber sealing ring 25 is clamped in the groove 29. The upper end of the T-shaped connecting ring 27 is fixedly connected to a plurality of support springs 33. The upper ends of the support springs 33 are fixedly connected to the annular cavity 8. An electromagnet 26 is provided inside the support spring 33. A plurality of electromagnets 26 are fixedly installed at the upper end of the annular cavity 8. After the electromagnet 26 is turned off, under the elastic force of the support spring 33, the T-shaped connecting ring 27 will move downward and drive the rubber sealing ring 25 to be clamped into the grooves 29 opened at the upper ends of a plurality of reflective baffles 16;

[0033] The second sealing mechanism includes a T-shaped liquid storage cavity 17 opened in the reflective baffle 16. An I-shaped rod 15 is slidably connected to the T-shaped liquid storage cavity 17. The upper end of the I-shaped rod 15 extends into the groove 29. A connecting spring 28 is sleeved outside the I-shaped rod 15. One end of the connecting spring 28 is fixedly connected to the groove 29, and the other end is fixedly connected to the I-shaped rod 15. Two T-shaped sealing rods 30 are slidably connected to the T-shaped liquid storage cavity 17. A rubber block is provided at one end of the T-shaped sealing rod 30 away from the reflective baffle 16. When a plurality of electromagnets 26 are turned on to adsorb the T-shaped connecting ring 27, the T-shaped connecting ring 27 moves to drive the rubber sealing ring 25 to disengage from the groove 29. Under the elastic force of the connecting spring 28, the I-shaped rod 15 returns to its original position upward. At the same time, the T-shaped sealing rod 30 will be retracted into the T-shaped liquid storage cavity 17 again to prevent the reflective baffle 16 from being unable to unfold normally.

[0034] Working principle: During use, connect the installation base 20 to the bracket installed on the ground so that the bottom plate 1 is set in an inclined state facing the sun. Turn on several electromagnets 26 to adsorb the T-shaped connecting ring 27. The movement of the T-shaped connecting ring 27 drives the rubber sealing ring 25 to disengage from the groove 29. Turn on the drive motor 19 to drive the drive gear 3 to rotate. The rotation of the drive gear 3 drives the four connecting gears 4 engaged with it to start rotating. Since the connecting gear 4 is connected to the lead screw 6, during the rotation of the connecting gear 4, the lead screw 6 will be driven to start rotating. The rotation of the lead screw 6 drives the connecting plate 2 to move upward. The movement of the connecting plate 2 drives the L-shaped connecting plate 7 to move upward. The upward movement of several L-shaped connecting plates 7 drives the heat insulation seat 14 to move synchronously. At the same time, during the movement of the L-shaped connecting plate 7, the toothed plate 32 will be driven to move synchronously. Since the toothed plate 32 is engaged with the toothed roller 5, during the rotation of the toothed roller 5, the reflective baffle 16 will move and unfold. Since the reflective baffle 16 and the surface of the bottom plate 1 are both provided with light-emitting coatings, when sunlight shines on the surface of the reflective baffle 16 and the bottom plate 1, the sunlight will be reflected to the position of the convex lens 24 at this time, and the sunlight entering the convex lens 24 is concentrated and irradiated on the surface of the hemispherical reaction tube 21;

[0035] The raw material gas enters the hemispherical reaction tube 21 through the connecting pipe 10 on the left side to react with the catalyst 11. The mixed gas generated after the reaction enters an external gas separation device through the outlet pipe 12. The synthesis gas hydrogen / carbon monoxide in the mixed gas is separated by the gas separation device, and the unreacted raw material gas methane / carbon dioxide is re-entered into the hemispherical reaction tube 21 through the connecting pipe 10 on the right side to react again. When the external environment is cloudy, at this time, the thermocouple 22 can be controlled through the wire 13 to heat the hemispherical reaction tube 21 so that the catalyst 11 reacts with the raw material gas;

[0036] After use, control the drive motor 19 to drive the drive gear 3 to rotate in the reverse direction. The L-shaped connecting plate 7 will move downward and drive the toothed roller 5 to rotate in the reverse direction. At this time, several reflective baffles 16 will close together again. At the same time, the heat insulation seat 14 and the top plate 9 will move downward. When the reflective baffle 16 changes from an inclined state to an upright state, at this time, the triangular rubber strip 31 between the two reflective baffles 16 will fit together. At the same time, the electromagnet 26 will be turned off. At this time, under the elastic force of the support spring 33, the T-shaped connecting ring 27 will move downward and drive the rubber sealing ring 25 to be clamped into the groove 29 opened at the upper end of several reflective baffles 16;

[0037] When the rubber sealing ring 25 moves downward, it presses the I-shaped rod 15 in the groove 29. At this time, the I-shaped rod 15 moves downward and squeezes the hydraulic oil in the T-shaped liquid storage cavity 17. After being squeezed, the hydraulic oil pushes the T-shaped sealing rod 30 to move outward. Through the contact between the triangular rubber strips 31 in the two light-reflecting baffles 16 and the T-shaped sealing rod 30, the sealing of the connection between the light-reflecting baffles 16 and the light-reflecting baffles 16 is achieved. By clamping the rubber sealing ring 25 into the groove 29, the sealing of the upper side of the light-reflecting baffle 16 is achieved, preventing frosting or icing on the surface of the convex lens 24 in rainy or snowy weather. When the rubber sealing ring 25 disengages from the groove 29, at this time, under the elastic force of the connecting spring 28, the I-shaped rod 15 returns upward to its original position, and at the same time, the T-shaped sealing rod 30 will be retracted into the T-shaped liquid storage cavity 17 again.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
