Description

Technical Field

[0001] This invention relates to the field of carbon dioxide resource utilization technology, specifically a carbon dioxide resource utilization device and a carbon dioxide resource utilization method. Background Technology

[0002] The large amounts of carbon dioxide emitted by human activities and the burning of fossil fuels in industrial and agricultural production remain in the atmosphere, contributing significantly to climate change. Faced with this increasingly severe environmental crisis, current methods primarily employ physical, chemical, and biological approaches to treat carbon dioxide. Physical methods mainly involve compressing and storing the collected carbon dioxide on the seabed or in underground mine tunnels. However, this method fails to utilize carbon dioxide as a resource or energy source and carries geological risks, potentially triggering geological disasters during crustal movements. Chemical methods synthesize organic compounds such as methanol and starch through chemical processes and highly efficient catalysts, but these methods suffer from complex processes, expensive catalysts, high costs, and low yields, hindering large-scale engineering implementation. Biological methods primarily rely on algae photosynthesis to absorb carbon dioxide, but these also present challenges in controllability. Therefore, there is an urgent need to develop a systematic device and method for the resource utilization of carbon dioxide to achieve its resource recovery. Summary of the Invention

[0003] To address the above problems, this invention provides a carbon dioxide resource utilization device and method. Solid carbon dioxide (dry ice) undergoes a heat exchange process, where room-temperature dry air exchanges heat with the dry ice, causing the dry ice to sublimate into low-temperature carbon dioxide gas. This low-temperature carbon dioxide gas further exchanges heat with room-temperature dry air and is then heated to room temperature. After pressure regulation and flow adjustment, it enters a carbon dioxide buffer tank, and is then pressurized and stored in a carbon dioxide storage tank. It is then used in conjunction with a civilian or industrial carbon dioxide plasma ignition device for heating and energy supply in civilian or industrial applications. The room-temperature dry air, after heat exchange, becomes cold air, which can be collected and used to provide a cooling source for nearby equipment or buildings requiring cooling or refrigeration. This invention provides a systematic solution for the resource utilization of carbon dioxide and is of great significance for addressing the climate crisis.

[0004] This invention is specifically achieved through the following technical solution: A carbon dioxide resource utilization device proposed according to this invention includes, from front to back, a dry ice sublimation device, a heat exchange device, a gas heating device, a pressure regulating and stabilizing device, a flow regulating device, a carbon dioxide buffer tank, a gas booster pump, and a carbon dioxide storage tank. The dry ice sublimation device includes an insulated storage tank, which is provided with an air compressed gas inlet I, a cold air outlet, and a low-temperature carbon dioxide gas outlet. The heat exchange device includes a heat exchange chamber, which is provided with a low-temperature carbon dioxide gas inlet, a near-room temperature carbon dioxide gas outlet, an air compressed gas inlet II, and a cold air outlet II. The low-temperature carbon dioxide gas inlet is connected to the low-temperature carbon dioxide gas outlet via a pipeline, and the near-room temperature carbon dioxide gas outlet is connected to the gas heating device. The carbon dioxide buffer tank includes a tank body, which is provided with a carbon dioxide gas inlet I and a carbon dioxide gas outlet I. The carbon dioxide storage tank body is provided with a carbon dioxide gas inlet II. The carbon dioxide gas inlet I is connected to the flow regulating device, the carbon dioxide gas outlet I is connected to the inlet of the gas booster pump, and the outlet of the gas booster pump is connected to the carbon dioxide gas inlet II.

[0005] In the aforementioned carbon dioxide resource utilization device, a first pressure sensor is installed on the connecting pipeline between the gas heating device and the pressure regulating device, a second pressure sensor is installed on the connecting pipeline between the pressure regulating device and the flow regulating device, and a flow sensor is installed on the connecting pipeline between the flow regulating device and the carbon dioxide buffer tank.

[0006] In the aforementioned carbon dioxide resource utilization device, the compressed air inlet I is connected to air compressor I, and the compressed air inlet II is connected to air compressor II; both cold air outlet I and cold air outlet II are connected to a cold air collection device through pipelines.

[0007] The aforementioned carbon dioxide resource utilization device also includes a metal spiral coil inside the heat-insulating storage tank. The metal spiral coil is spirally arranged along the axial direction of the heat-insulating storage tank. One end of the metal spiral coil is connected to the compressed air inlet I, and the other end is connected to the cold air outlet I. The inner cavity of the heat-insulating storage tank is filled with dry ice.

[0008] The aforementioned carbon dioxide resource utilization device includes an inner shell and an outer shell in the heat-insulating storage tank, with a vacuum heat-insulating layer between the inner and outer shells.

[0009] The aforementioned carbon dioxide resource utilization device includes a pressure gauge I, a temperature gauge I, and a dry ice feeding valve installed on the top of the heat-insulated storage tank; and a pressure gauge II and a temperature gauge II installed on the top of the heat exchange box.

[0010] In the aforementioned carbon dioxide resource utilization device, a metal heat exchange tube grid is provided inside the heat exchange box. The metal heat exchange tube grid includes multiple heat exchange tubes arranged in parallel. The axial direction of the heat exchange tubes is parallel to the axial direction of the heat exchange box. The bottom or top of two adjacent heat exchange tubes are interconnected. Finally, the multiple heat exchange tubes are interconnected to form a carbon dioxide gas heat exchange channel. One end of the carbon dioxide gas heat exchange channel is connected to the low-temperature carbon dioxide gas inlet, and the other end is connected to the near-room temperature carbon dioxide gas outlet.

[0011] The aforementioned carbon dioxide resource utilization device is further equipped with a third pressure sensor on the carbon dioxide buffer tank and a carbon dioxide gas outlet II and a fourth pressure sensor on the carbon dioxide storage tank. The carbon dioxide gas outlet II is connected to a civilian or industrial plasma ignition device through a pipeline.

[0012] In the aforementioned carbon dioxide resource utilization device, a bypass is connected between the gas heating device and the first pressure sensor, and a gas detection alarm is installed on the bypass.

[0013] This invention also provides a method for the resource utilization of carbon dioxide, which uses the carbon dioxide resource utilization device described above, and the specific steps include: (1) Dry ice is placed in the heat-insulated storage tank of the dry ice sublimation device. The heat-insulated storage tank is equipped with a metal spiral coil. One end of the metal spiral coil is connected to the air compressor inlet I, and the other end is connected to the cold air outlet I. The air compressor inlet I is connected to the air compressor I. The ambient temperature dry air enters the metal spiral coil through the air compressor I and the air compressor inlet I. The ambient temperature dry air in the metal spiral coil exchanges heat with the dry ice in the heat-insulated storage tank. The low temperature dry ice absorbs the heat of the ambient temperature dry air and sublimates into low temperature carbon dioxide gas. The air temperature in the metal spiral coil decreases and becomes cold air. The cold air enters the cold air collection device through the cold air outlet I. The low temperature carbon dioxide gas enters the metal heat exchange grid of the heat exchange device. (2) In the heat exchange device, room temperature dry air enters the heat exchange box through air compressor II and air compressed gas inlet II. Low temperature carbon dioxide gas in the metal heat exchange tube grid exchanges heat with room temperature dry air in the heat exchange box. The carbon dioxide gas gradually heats up and approaches room temperature. Finally, it is output through near room temperature carbon dioxide gas outlet and enters the gas heating device. After the room temperature dry air exchanges heat with low temperature carbon dioxide gas, it becomes cold air and is output through cold air outlet II and enters the cold air collection device. (3) The gas heating device heats the input near-room temperature carbon dioxide gas to room temperature. Then, the room temperature carbon dioxide gas enters the pressure regulating and stabilizing device after the pressure is measured by the first pressure sensor. After the pressure is measured by the second pressure sensor, the carbon dioxide gas enters the flow regulating device for flow adjustment. After the flow is monitored by the flow sensor, it is transported to the carbon dioxide buffer tank. (4) When the pressure of carbon dioxide gas in the carbon dioxide buffer tank rises to 0.4~1MPa, open the valve on carbon dioxide gas outlet I to allow carbon dioxide gas in the carbon dioxide buffer tank to enter the gas booster pump. The gas booster pump pressurizes the carbon dioxide gas to 0.8~2MPa and then delivers it to the carbon dioxide storage tank. The carbon dioxide gas in the carbon dioxide storage tank is delivered to the civil or industrial plasma ignition device through carbon dioxide outlet II, so that it is converted into heat energy for heating and energy supply.

[0014] Furthermore, the high-temperature exhaust gas generated after the carbon dioxide plasma ignition device is powered is collected and enters the exhaust gas channel. The collected exhaust gas is first treated to remove oil fumes. The gas after oil fume removal is then enriched with carbon dioxide through a polyimide organic membrane, etc. The enriched carbon dioxide gas is compressed and stored, or made into dry ice using a dry ice maker, for the next round of recycling. Alternatively, the enriched carbon dioxide gas can be directly sent to the first pressure sensor through a delivery pipeline, and after pressure measurement, it enters the subsequent connection device for recycling.

[0015] Compared with existing technologies, this invention has significant advantages and beneficial effects. Through the above technical solution, this invention achieves considerable technological advancement and practicality, and has broad application value, possessing at least the following advantages: The large-scale emission of high-concentration carbon dioxide gas from industrial and agricultural production exacerbates the "greenhouse effect." This high-concentration carbon dioxide gas can be collected, processed, and then made into dry ice using existing dry ice-making machines for storage. However, this invention utilizes this dry ice through its carbon dioxide resource utilization device and method. In the carbon dioxide resource utilization device designed in this invention, dry ice sublimates after heat exchange with room-temperature dry air to obtain low-temperature carbon dioxide gas. This low-temperature carbon dioxide gas further exchanges heat with room-temperature dry air, raising its temperature. It is then further heated to room temperature by a gas heating device. After being heated to room temperature, the carbon dioxide gas is pressure-regulated and its flow rate adjusted before entering a carbon dioxide buffer tank. It is then pressurized by a gas booster pump and stored in a carbon dioxide storage tank. Subsequently, it is used in conjunction with a civilian or industrial carbon dioxide plasma ignition device for heating and energy supply. The carbon dioxide-based exhaust gas produced after the plasma ignition device can be collected, processed, and made into dry ice, which is then recycled through the carbon dioxide resource utilization device of this invention. After heat exchange, the dry air at room temperature becomes cold air. The collected cold air can be used to provide a cooling source for nearby equipment or buildings that need cooling, thus achieving energy conservation and consumption reduction.

[0016] This invention can, to a certain extent, replace fossil fuels, reducing fossil fuel consumption and saving energy. It also prevents the continuous release of high concentrations of carbon dioxide generated during industrial and agricultural production into the atmosphere, thus avoiding the exacerbation of the greenhouse effect and preventing the sustained release of greenhouse gases. Furthermore, the cold air generated during resource utilization can be fully utilized, further saving energy consumption. This invention provides a reliable and systematic solution for the resource utilization of high concentrations of carbon dioxide gas generated in industrial and agricultural production, and is of great significance for addressing the global climate crisis.

[0028] Furthermore, the top of the thermal insulation storage tank 1.1 is also equipped with a pressure gauge I 1.7, a temperature gauge I 1.8, and a dry ice feeding valve 1.9.

The air compressed gas inlet II 2.5 is connected to the air compressor II 2.7, and the cold air outlet II 2.6 is connected to the cold air collection device 12 via a pipeline.

[0030] The metal heat exchanger grid 2.2 comprises multiple heat exchanger tubes arranged in parallel, with the axial direction of the heat exchanger tubes parallel to the axial direction of the heat exchange chamber. The bottoms or tops of adjacent heat exchanger tubes are interconnected, ultimately forming a carbon dioxide gas heat exchange channel. One end of the carbon dioxide gas heat exchange channel is connected to a low-temperature carbon dioxide gas inlet 2.3, and the other end is connected to a near-room temperature carbon dioxide gas outlet 2.4.

Finally, it exits through the near-room temperature carbon dioxide gas outlet 2.4 and enters the gas heating device 3.

[0031] Furthermore, the shell of the heat exchange box 2.1 includes an inner shell and an outer shell, and a vacuum insulation layer is provided between the inner and outer shells.

[0032] Furthermore, a pressure gauge II 2.8 and a temperature gauge II 2.9 are installed on the top of the heat exchange chamber 2.1.

[0033] In one embodiment, the gas heating device 3 is a commercially available carbon dioxide pipeline heater.

[0034] In one embodiment, the pressure regulating and stabilizing device 5 is a commercially available gas pressure regulating and stabilizing device, such as a self-regulating pressure regulating valve. After pressure regulation and stabilization, the carbon dioxide gas pressure in the conveying system is not higher than 0.4 MPa.

[0035] In one embodiment, the flow regulating device 7 is a commercially available linear electric actuator, such as the LK80 linear electric actuator manufactured by Force Control Valve Co., Ltd., but the present invention is not limited thereto.

[0036] like Figure 4 As shown, the carbon dioxide buffer tank 9 includes a tank body 9.1, on which a carbon dioxide gas inlet I 9.2, a carbon dioxide gas outlet I 9.3, and a third pressure sensor 9.4 are provided. The carbon dioxide gas inlet I 9.2 is connected to the flow regulating device 7 via a pipeline, and the carbon dioxide gas outlet I 9.3 is connected to the inlet of the gas booster pump 10 via a pipeline.

[0037] The structure of the carbon dioxide storage tank 11 is the same as that of the carbon dioxide buffer tank 9. The carbon dioxide storage tank 11 is equipped with a carbon dioxide gas inlet II 11.1, a carbon dioxide gas outlet II 11.2, and a fourth pressure sensor 11.3. The carbon dioxide gas inlet II 11.1 is connected to the outlet of the gas booster pump 10, and the carbon dioxide gas outlet II 11.2 is connected to a civil or industrial plasma ignition device through a pipeline.

[0038] After the pressure value of carbon dioxide buffer tank 9 reaches M, the valve on carbon dioxide gas outlet I9.3 is opened, allowing the carbon dioxide gas in carbon dioxide buffer tank 9 to enter gas booster pump 10. Gas booster pump 10 pressurizes the carbon dioxide gas to 2M and then delivers it to carbon dioxide storage tank 11.

[0039] In one embodiment, M = 0.4~1 MPa.

[0040] The plasma ignition device can be a commercially available, mature product, such as a microwave plasma ignition device of model WY manufactured by a microwave company in Nanjing.

[0047] In other embodiments, a gas detector 14 can be installed on the gas delivery pipeline after the gas heating device. The gas detector 14 is not connected to the inside of the pipeline; it is simply installed on the pipeline. The gas detector 14 can detect the carbon dioxide concentration in the air in real time, and will promptly sound an alarm when the carbon dioxide concentration exceeds a threshold, thereby ensuring the safety of the operators.

[0048] Furthermore, the gas detection alarm 14 can be installed on the pipeline between the first pressure sensor 4 and the pressure regulating device 5, or on the pipeline between the pressure regulating device 5 and the second pressure sensor 6, or on the pipeline between the second pressure sensor 6 and the flow regulating device 7, or on the pipeline between the flow regulating device 7 and the flow sensor 8, or on the pipeline between the flow sensor 8 and the carbon dioxide buffer tank 9, or on the pipeline between the carbon dioxide buffer tank 9 and the gas booster pump 10, or on the pipeline between the gas booster pump 10 and the carbon dioxide storage tank 11. Alternatively, the gas detection alarm 14 can be installed at two or more of the above locations simultaneously.

[0049] In other embodiments, a bypass 15 can be added between the gas heating device 3 and the first pressure sensor 4.

Excess carbon dioxide gas is introduced into another set of delivery pipelines through the bypass 15, ultimately entering the carbon dioxide storage tank on the bypass.

[0050] In one embodiment, the gas detection alarm 14 is also installed on the bypass 15.

[0051] The gas detector alarm 14 can be selected from the Jiupu GTYQ-JIUP-30 industrial and commercial point-type gas detector, but the present invention is not limited thereto.

[0052] The methods for utilizing carbon dioxide resources using the above-mentioned carbon dioxide resource utilization devices include: (1) Dry ice is placed into the insulated storage tank 1.1 of the dry ice sublimation device 1 through the dry ice feeding valve 1.9. The insulated storage tank 1.1 is equipped with a metal spiral coil 1.6. One end of the metal spiral coil 1.6 is connected to the compressed air inlet I1.2, and the other end is connected to the cold air outlet I1.3. The compressed air inlet I1.2 is connected to the air compressor I1.5. The ambient temperature dry air enters the metal spiral coil 1.6 through the air compressor I1.5 and the compressed air inlet I1.2. The ambient temperature dry air in the metal spiral coil 1.6 exchanges heat with the dry ice in the inner cavity of the insulated storage tank 1.1. The low temperature dry ice absorbs the heat of the ambient temperature dry air in the metal spiral coil 1.6 and sublimates into carbon dioxide gas, which increases the air pressure in the insulated storage tank 1.1. The air temperature in the metal spiral coil 1.6 decreases and becomes cold air. The sublimation rate of dry ice and the pressure inside the insulated storage tank 1.1 can be controlled by adjusting the input rate of ambient temperature dry air. Cold air enters the cold air collection device 12 through the cold air outlet Ⅰ1.3. The cold air in the cold air collection device 12 can be transported to equipment or buildings near the carbon dioxide resource utilization device that require cooling through pipelines and flow control to provide cooling effect. The sublimated low-temperature carbon dioxide gas enters the metal heat exchange grid 2.2 of the heat exchange device 2 through the connected pipeline.

[0053] (2) In heat exchange device 2, ambient temperature dry air enters the heat exchange chamber of the heat exchange device through air compressor II 2.7 and compressed air inlet II 2.5. Low temperature carbon dioxide gas in metal heat exchange tube grid 2.2 exchanges heat with ambient temperature dry air in heat exchange chamber 2.1, causing the air temperature to decrease. The carbon dioxide gas in metal heat exchange tube grid 2.2 gradually heats up and approaches ambient temperature, and finally exits through near-ambient temperature carbon dioxide gas outlet 2.4 and enters gas heating device 3. After exchanging heat with low temperature carbon dioxide gas, ambient temperature dry air becomes cold air, which is exited through cold air outlet II 2.6 and enters cold air collection device 12.

[0054] (3) The gas heating device 3 heats the input near-room temperature carbon dioxide gas to room temperature. Then, the room temperature carbon dioxide gas enters the pressure regulating device 5 after the pressure is measured by the first pressure sensor 4. After the pressure is regulated, the carbon dioxide gas enters the flow regulating device 7 after the pressure is measured by the second pressure sensor 6. After the flow is monitored by the flow sensor 8, it is transported to the carbon dioxide buffer tank 9.

[0055] (4) When the pressure of carbon dioxide gas in carbon dioxide buffer tank 9 rises to M (M=0.4~1MPa) (the specific value of M depends on the volume of carbon dioxide buffer tank), open the valve on carbon dioxide gas outlet I 9.3 to allow the carbon dioxide gas in carbon dioxide buffer tank 9 to enter gas booster pump 10. Gas booster pump 10 pressurizes the carbon dioxide gas to 2M (M=0.4~1MPa) and then delivers it to carbon dioxide storage tank 11. Through pipeline design, the carbon dioxide gas in carbon dioxide storage tank 11 is delivered to civil or industrial plasma ignition device through carbon dioxide outlet II 11.2, so that it is converted into heat energy for heating and energy supply, realizing resource utilization. The high-temperature exhaust gas generated after the carbon dioxide plasma ignition device is powered is collected and enters the exhaust gas channel. The collected exhaust gas is first treated to remove oil fumes, which can be achieved using a fume purifier (such as Donaldson's fume purifier). The gas after oil fume removal is then enriched with carbon dioxide using a polyimide organic membrane, etc. The enriched carbon dioxide gas is compressed and stored, or made into dry ice using a dry ice maker, for further recycling. Alternatively, the enriched carbon dioxide gas can be directly sent to the first pressure sensor through a delivery pipeline, and after pressure measurement, it enters subsequent equipment for recycling.

[0056] Example 1 This embodiment uses, as follows: Figure 1 The carbon dioxide resource utilization device shown is used. After the carbon dioxide resource utilization device is fully debugged, dry ice is loaded into the heat-insulated storage tank 1.1. The dry ice consists of cubic particles with a side length of 20 mm, and the mass of dry ice loaded into the heat-insulated storage tank 1.1 at one time is 20 kg. After the dry ice is loaded, the air compressor I 1.5 is started. Room temperature dry air from the environment enters the metal spiral coil 1.6 through the air compressor I 1.5 and the compressed air inlet I 1.2. The flow rate of the compressed air is set to 50 L / min, and the initial temperature of the compressed air is 20℃. The room temperature dry air in the metal spiral coil 1.6 exchanges heat with the dry ice in the dry ice sublimation device 1. The low temperature dry ice absorbs the heat from the room temperature dry air in the metal spiral coil 1.6 and sublimates into carbon dioxide gas, increasing the air pressure in the heat-insulated storage tank 1.1. The air temperature in the metal spiral coil 1.6 decreases to become cold air. The cold air is output through the cold air outlet I1.3 and enters the cold air collection device 12. The sublimated low-temperature carbon dioxide gas enters the metal heat exchange grid 2.2 of the heat exchange device 2 through the connected pipeline.

[0057] Air compressor II 2.7 is started, and ambient temperature dry air enters the internal cavity of heat exchange chamber 2.1 through air compressor II 2.7 and compressed air inlet II 2.5. The flow rate of compressed air is set to 50 L / min, and the initial temperature of compressed air is 20℃. Low-temperature carbon dioxide gas exchanges heat with the ambient temperature dry air in heat exchange chamber 2.1 in metal heat exchange tube grid 2.2, causing the air temperature to decrease. The carbon dioxide gas in metal heat exchange tube grid 2.2 gradually heats up and approaches ambient temperature, and finally exits through near-ambient temperature carbon dioxide gas outlet 2.4 and enters gas heating device 3. After exchanging heat with low-temperature carbon dioxide gas, the ambient temperature dry air becomes cold air, which is exited through cold air outlet II 2.6 and enters cold air collection device 12.

[0058] Gas heating device 3 heats the input near-room temperature carbon dioxide gas to room temperature. Then, the room temperature carbon dioxide gas enters the pressure regulating device 5 after the pressure is measured by the first pressure sensor 4. After the pressure is regulated, the carbon dioxide gas enters the flow regulating device 7 after the pressure is measured by the second pressure sensor 6. After the flow is monitored by the flow sensor 8, it is delivered to the carbon dioxide buffer tank 9.

[0059] Once the carbon dioxide gas pressure in the carbon dioxide buffer tank 9 reaches 0.4 MPa, the valve on the carbon dioxide gas outlet I 9.2 is opened, allowing the carbon dioxide gas in the buffer tank 9 to enter the gas booster pump 10. The gas booster pump 10 pressurizes the carbon dioxide gas to 0.8 MPa and then delivers it to the carbon dioxide storage tank 11. The carbon dioxide gas in the storage tank 11 is then delivered to the plasma ignition device through the carbon dioxide outlet II 11.2, where it is converted into heat energy for heating. The flame temperature of the plasma ignition device is adjustable from room temperature to 2000°C. A tail gas collection device is installed above the plasma ignition device. The high-temperature tail gas generated after the carbon dioxide plasma ignition device supplies power is collected by the tail gas collection device and degreased. Subsequently, the carbon dioxide is enriched through a polyimide organic membrane and then made into dry ice by a dry ice maker for the next round of recycling.

A method for the resource utilization of carbon dioxide, characterized in that, The carbon dioxide resource utilization device according to any one of claims 1-9 is used, and the specific steps include: (1) Place dry ice into the insulated storage tank (1.1) of the dry ice sublimation device (1). The insulated storage tank (1.1) is equipped with a metal spiral coil (1.6). One end of the metal spiral coil (1.6) is connected to the air compressor inlet I (1.2), and the other end is connected to the cold air outlet I (1.3). The air compressor inlet I (1.2) is connected to the air compressor I (1.5). External ambient temperature dry air passes through the air compressor I (1.5) and the air compressor inlet I (1.2). Entering the metal spiral coil (1.6), the ambient temperature dry air in the metal spiral coil (1.6) exchanges heat with the dry ice in the heat-insulating storage tank (1.1). The low temperature dry ice absorbs the heat of the ambient temperature dry air and sublimates into low temperature carbon dioxide gas. The air temperature in the metal spiral coil (1.6) decreases and becomes cold air. The cold air enters the cold air collection device (12) through the cold air outlet I (1.3). The low temperature carbon dioxide gas enters the metal heat exchange grid (2.2) of the heat exchange device (2). (2) In the heat exchange device (2), the ambient temperature dry air enters the heat exchange box (2.1) through the air compressor II (2.7) and the compressed air inlet II (2.5). The low temperature carbon dioxide gas in the metal heat exchange grid (2.2) exchanges heat with the ambient temperature dry air in the heat exchange box (2.1). The carbon dioxide gas gradually heats up and approaches ambient temperature. Finally, it is output through the near ambient temperature carbon dioxide gas outlet (2.4) and enters the gas heating device (3). After the ambient temperature dry air exchanges heat with the low temperature carbon dioxide gas, it becomes cold air and is output through the cold air outlet II (2.6) and enters the cold air collection device (12). (3) The gas heating device (3) heats the input near-room temperature carbon dioxide gas to room temperature. Then, the room temperature carbon dioxide gas enters the pressure regulating device (5) after the pressure is measured by the first pressure sensor (4). After the pressure is measured by the second pressure sensor (6), the carbon dioxide gas enters the flow regulating device (7) for flow adjustment. After the flow is monitored by the flow sensor (8), it is transported to the carbon dioxide buffer tank (9). (4) When the carbon dioxide gas pressure in the carbon dioxide buffer tank (9) rises to 0.4~1MPa, open the valve on the carbon dioxide gas outlet I (9.3) to allow the carbon dioxide gas in the carbon dioxide buffer tank (9) to enter the gas booster pump (10). The gas booster pump (10) pressurizes the carbon dioxide gas to 0.8~2MPa and then delivers it to the carbon dioxide storage tank (11). The carbon dioxide gas in the carbon dioxide storage tank (11) is delivered to the civil or industrial plasma ignition device through the carbon dioxide outlet II (11.2) to convert it into heat energy for heating.
