Description

Technical Field

[0001] This utility model relates to the field of greenhouse gas treatment technology, and in particular to a greenhouse gas treatment system. Background Technology

[0002] Global warming, caused by the combined effects of greenhouse gases produced by human industrialization and the Earth's positive feedback system, has become a climate catastrophe, posing a significant challenge to sustainable development. Besides causing global warming and its devastating consequences, greenhouse gases have also directly led to severe pollution of human living environments and serious degradation of the Earth's ecosystems since industrialization, driven by the development of industries such as energy, mining, chemicals, and agriculture. Therefore, how to capture, store, or convert greenhouse gases has become a crucial technological problem that needs to be solved.

[0003] For example, prior patent CN201885241U discloses a greenhouse gas treatment system, mentioning the combustion of captured greenhouse gases to ultimately convert them into clean gases or release other component gases with a high oxygen content into the air, thereby completely removing greenhouse gases and eradicating their greenhouse effect. However, this prior patent only involves combustion of greenhouse gases without converting them into products with high use value. Similarly, prior patent CN105271178B discloses a method for converting greenhouse gases into carbon, specifically utilizing the strong reducing properties of metal hydrogen compounds (e.g., metal hydrides, aluminum hydrides, borohydrides, etc.) to spontaneously convert greenhouse gases such as carbon dioxide into carbon materials under certain conditions. However, in its application, metal hydrogen compounds are used as… Catalysts are costly and their efficiency needs improvement. Catalysts also have a certain impact on product purity. In addition, this application only produces elemental carbon, resulting in a single product type and the waste of many elements. For example, the prior patent CN118598739A discloses a method for the synergistic conversion of two greenhouse gases and its application, specifically disclosing the preparation of liquid oxygen-containing compound formaldehyde by oxidizing methane and reducing carbon dioxide at room temperature. However, its processing capacity is limited, and the types of greenhouse gases processed are also limited. Another example is the high-voltage discharge catalytic reactor disclosed in the prior patent CN201520655391.0, which can process greenhouse gases but has low processing efficiency. At the same time, a large amount of residual greenhouse gases and by-product hydrocarbons and carbon-oxygen gases (such as carbon monoxide) are generated, posing dual problems of safety and efficiency. Multi-stage processing greatly increases the equipment size and energy consumption. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] refer to Figure 1 This invention discloses a greenhouse gas treatment system comprising:

[0029] Gas capture and storage devices;

[0030] A gas purification device is located downstream of the gas collection and storage device and is connected to the pipeline of the gas collection and storage device.

[0031] The reactor is located downstream of the gas purification device and is connected to the pipeline of the gas purification device.

[0037] A solid final product collection device is located downstream of the solid product testing device and is connected to the conveyor belt of the solid product testing device.

[0038] In this embodiment of the invention, greenhouse gases are captured using a gas capture and storage device. After capture, the greenhouse gases are sent to a gas purification device to remove particulate impurities such as dust and to separate different greenhouse gases before being sent to a reactor. In the reactor, the greenhouse gases are decomposed into various mixed elemental gases and elemental solids. These mixed elemental gases are first collected by a gas product collection device and then sent to a gas product separation device to separate the mixed elemental gases into individual elemental gas final products, which are collected in different gas final product collection devices. For gases in the mixed gas that have not been completely decomposed (reduced), they can be sent back to the reactor for further decomposition (reduction). Simultaneously, the elemental solid final products are collected in a solid... In the solid product collection device, solid products that fail the solid product testing device (which mainly tests the morphology, size, and purity of the product and is commercially available) can be transferred back to the reaction to be re-pyrolyzed (reduced). It should be noted that the gas purification device includes, for example, a gas separation membrane unit for separating different greenhouse gases, especially selecting sulfur-containing greenhouse gases and carbon-containing greenhouse gases to be treated separately. In this case, the solid element is elemental sulfur or elemental carbon, and the two are not mixed. In addition, for elemental carbon, depending on the desired form, by controlling parameters such as the number of re-firing cycles, temperature, current, and voltage, final products such as carbon nanoparticles, carbon nanotubes, or graphene can be produced. This process is existing technology and will not be elaborated here. The greenhouse gas treatment system provided in this embodiment can capture, store, and treat a variety of greenhouse gases. The products are gaseous and solid elements with high atom utilization. The treatment process is safe and stable, with low energy consumption and no catalyst used. At the same time, the production process has zero carbon emissions and zero waste emissions. The final products are all elemental products with high added value. Since the raw material is greenhouse gas, the manufacturing cost is low, which is conducive to significantly reducing the market price of related elemental products.

[0039] In this embodiment of the invention, the gas capture and storage device is used to capture greenhouse gases. For example, a carbon dioxide capture and storage device is used to capture carbon dioxide generated in the atmosphere or at the factory or agricultural product processing end. Similarly, a methane capture and storage device is used to capture methane gas, a nitrous oxide capture and storage device is used to capture nitrous oxide gas, a hydrofluorocarbon capture and storage device is used to capture hydrofluorocarbons, a perfluorocarbon capture and storage device is used to capture perfluorocarbons, and a sulfur hexafluoride capture and storage device is used to capture sulfur hexafluoride. These capture and storage devices are commercially available and will not be described in detail here. The gas purification device can be, for example, a pressure swing adsorption purification device or... Other purification devices used in existing technologies, such as separation membrane devices, will not be described in detail here. The reactor is preferably a plasma pyrolysis reactor, which uses ultra-low power high voltage electromagnetic force to decompose greenhouse gases. It can directly destroy the intermolecular forces of greenhouse gases and promote the combination of the same ions to form elemental substances. For example, carbon dioxide molecules form carbon and oxygen under the action of ultra-low power high voltage electromagnetic force, methane molecules form carbon and hydrogen under the action of ultra-low power high voltage electromagnetic force, nitrous oxide forms oxygen and nitrogen under the action of ultra-low power high voltage electromagnetic force, hydrofluorocarbons form carbon, hydrogen, and fluorine under the action of ultra-low power high voltage electromagnetic force, and so on.

Understandably, after the mixed gas products are separated to form elemental gases, it is preferable to install a detection device to detect the purity of the gas, facilitating the classification and processing of gases of different purities as needed.

[0042] In one specific embodiment, the reactor includes a cooling device (not shown). The cooling device is used to cool the gaseous and solid elements formed in the reaction, and preferably the cooling device is located downstream of the reactor.
