Description

Technical Field

[0001] The present invention belongs to the technical field of carbon dioxide conversion, and particularly relates to a carbon dioxide conversion reactor based on the synergistic effect of plasma and photothermal energy. Background Art

[0002] The synergistic effect of plasma and photothermal energy is a cutting-edge technology that combines the plasma resonance effect and the photothermal conversion process. Through the interaction between the two, efficient energy utilization and function enhancement are achieved. Carbon dioxide is converted into fuels or high-value-added chemicals (such as CO, methane, methanol, etc.) through the efficient energy utilization of the ion resonance effect and the photothermal conversion process. The CO2 conversion reactor can break through the efficiency limitations of traditional thermal catalysis or photocatalysis and provide key technical support for the carbon neutrality goal.

[0003] Common carbon dioxide conversion reactors convert carbon dioxide under the catalytic action of a catalyst by using carbon dioxide and other conversion gases such as hydrogen in a closed space. However, in actual use, as the continuous conversion of carbon dioxide progresses, the catalytic rate of the catalyst gradually weakens because the catalyst is not easy to install and replace. Therefore, we provide a carbon dioxide conversion reactor based on the synergistic effect of plasma and photothermal energy to solve the above technical problems. Summary of the Invention

[0007] The present invention is further configured such that engaging drive columns are slidably disposed on opposite side surfaces of the catalytic support frame body. A support disc is fixedly connected to one side of the engaging drive column. A second return spring is fixedly connected between the support disc and the catalytic support frame body. The second return spring is sleeved outside the engaging drive column, and the other end of the engaging drive column is slidably engaged with the inner wall of the engaging adjustment groove.

Positioning grooves are formed on the other opposite inner side walls of the catalytic support frame body, and the positioning grooves are adapted to the corresponding extension blocks. A plurality of assembly cross bars are fixedly connected to the side surface of the first opening and closing cover away from the first air inlet pipe, and the assembly cross bars penetrate through the hollow catalytic frame and the second opening and closing cover.

[0008] The present invention is further configured such that a first guiding chute is formed on the side surface of the first opening and closing cover close to the first air inlet pipe. A bidirectional rack is slidably disposed inside the first guiding chute through an extension pillar. An electric telescopic rod is fixedly connected to the side surface of the first opening and closing cover close to the first air inlet pipe through a support seat, and the output section of the electric telescopic rod is fixedly connected to the bidirectional rack. A second guiding chute is formed on the side surface of the second opening and closing cover close to the air outlet pipe.

[0031] Further, the opening and closing control assembly 2 further includes an opening and closing support disk 202 and an opening and closing support frame 203. The opening and closing support disk 202 is fixedly connected to the corresponding first intake pipe 105, second intake pipe 106, and outlet pipe 107. An opening and closing guide groove 204 corresponding to the opening and closing control plate 201 is formed on one side surface of the opening and closing support disk 202. An extending transmission block that is slidably engaged with the corresponding opening and closing guide groove 204 is fixedly connected to one side surface of the opening and closing control plate 201.

A sector gear 206 is fixedly connected to the circumferential side surface of the opening and closing support frame 203. The sector gear 206 is meshed with the corresponding bidirectional rack 117 and transmission rack 119.

[0032] The operation process of this embodiment is as follows: Before the conversion of carbon dioxide, the hollow catalytic frame 102 is installed inside the catalytic support frame 101 by using the clamping and matching effect between the hollow catalytic frame 102 and the catalytic support frame 101. The specific operation is as follows:

[0033] Control the extension block 115 to move towards the corresponding positioning groove. At the same time, the hollow catalytic frame 102 pushes the corresponding clamping support block 108 to move horizontally. The telescopic column 110 and the first return spring 111 are compressed. At the same time, under the sliding cooperation of the inclined sliding surface of the clamping control groove 109 and the clamping transmission column 112, the clamping transmission column 112 slides along the inclined sliding surface of the clamping control groove 109, thereby pushing the clamping transmission column 112 to move horizontally. The second return spring 113 is stretched. As the hollow catalytic frame 102 moves horizontally, the clamping transmission column 112 moves along the surface of the clamping support block 108 to the side surface of the hollow catalytic frame 102 until the clamping transmission column 112 is aligned with the corresponding clamping hole 114. Under the elastic recovery action of the second return spring 113, the clamping transmission column 112 is inserted into the corresponding clamping hole 114. Under the plugging and matching action of the clamping transmission column 112 and the corresponding clamping hole 114, the position limitation of the hollow catalytic frame 102 is realized.

[0034] At the same time, control the second cover 104 to approach the first cover 103. The second cover 104 and the catalytic support frame 101 installed with the hollow catalytic frame 102 slide along the circumferential side surface of the assembly cross bar 116 and are fixed with nuts until the three are closely attached to form a sealed conversion space. The hollow catalytic frame 102 is located inside the sealed conversion space. When carbon dioxide conversion is required, drive the double-sided rack 117 to move horizontally through the electric telescopic rod 118. Under the meshing action of the double-sided rack 117 and the sector gear 206 of the opening and closing control assembly 2 on the first air inlet pipe 105 and the second air inlet pipe 106, the sector gear 206 drives the opening and closing support frame 203 to rotate synchronously, and the inclined sliding groove 205 moves synchronously. Under the sliding cooperation of the inclined sliding groove 205 and the corresponding transmission column, the extended transmission block drives the opening and closing control plate 201 to slide along the track of the opening and closing guide groove 204, so that the opening and closing control assembly 2 is in an open state, and carbon dioxide, hydrogen and other gases required for carbon dioxide photocatalysis are introduced into the conversion space. When the gas passes through the catalyst inside the hollow catalytic frame 102, the catalyst is used to react with carbon dioxide and other gases, and gases such as methane are formed through the catalytic reaction, thereby realizing the conversion of carbon dioxide. After the carbon dioxide conversion is completed, disconnect the power supply of the electromagnet, and the magnetic effect of the electromagnet disappears. Under the elastic recovery action of the transmission return spring 120, the extended cross bar drives the transmission rack 119 to move horizontally. Under the meshing action of the transmission rack 119 and the sector gear 206 of the air outlet pipe 107 corresponding to the opening and closing control assembly 2, the air outlet pipe 107 corresponding to the opening and closing control assembly 2 is in an open state, and the converted gas is discharged through the air outlet pipe 107 and collected.
