Embodiment 1

[0087] Example 1 - planting fast-growing plants to capture CO 2

[0088] Use the photosynthesis of fast-growing plants such as fast-growing herbs, woody plants, algae, lichens or mosses to convert gaseous CO in the atmosphere 2 , transferred into the biosphere to form solid organic carbon compounds for carbon storage and sequestration; taking the example of planting hybrid pennisetum in the middle and lower reaches of the Yangtze River for forming, carbon storage, and sequestration, the specific steps are as follows:

[0089] (1) planting

[0090] Choose a place with deep, fertile, sunny, and convenient irrigation. Before planting, plow and form a ridge. The ridge width is preferably 2-3m to facilitate drainage and field management.

[0091] Sow when the temperature is stable above 10°C, select strong stems with full bud eyes, no diseases, insects, and damages as the stems, cut them into small sections, each section has 1 to 2 axillary buds; the row spacing between plants ...

Embodiment 2

[0102] Example 2 - capture CO by physical absorption 2

[0103] Take Na 2 O, K 2 O, Al 2 o 3 , MgO, CaO, Li 2 O, ZrO 2 , Li 2 ZrO 3 , Li 4 SiO 4 , activated carbon, zeolite and other CO 2 Examples of solid adsorbents.

[0104] Utilize Na 2 O, K 2 O, Al 2 o 3 , MgO, CaO, Li 2 O, ZrO 2 , Li 2 ZrO 3 , Li 4 SiO 4 and other metal oxide adsorbents for CO 2 The adsorption capacity is very high, and it can carry out multiple cycles of adsorption without pollution. Or use adsorbents such as zeolite, activated carbon and activated carbon fiber, porous materials, molecular sieve materials, and nanotubes to adsorb CO with developed pore structure, large specific surface area, excellent adsorption performance, and stable physical and chemical properties. 2 , to capture carbon resources.

[0105] The solid sorbent converts CO during the reaction 2 Converted into solid form for easy storage, transportation and utilization. Wide source of raw materials, no second...

Embodiment 3

[0110] Example 3 - Membrane separation method captures CO 2

[0111] see figure 1 , the membrane separation method captures CO 2 Take cellulose acetate or ethyl cellulose as examples of membrane materials.

[0112] Separation of CO is achieved by using the different transmission rates of gases through the membrane driven by pressure. 2 , for the purpose of purification and recovery.

[0113] Specific steps are as follows:

[0114] 1. The air passes through the air filter to remove particulate matter.

[0115] 2. The filtered clean gas enters the gas membrane separation device through the air booster.

[0116] 3. CO separated by membrane separation device 2 , into the CO through the air booster 2 Storage tower (tank).

[0117] 4. Membrane separation device to separate CO 2 Afterwards, the exhaust gas is released into the atmosphere.

Abstract

Disclosed are a device and method for trapping carbon resources in the atmosphere. The method includes the following steps: (1), transferring gaseous CO2 in the atmosphere into the biosphere to form solid organic carbon compounds through photosynthesis of rank vegetation, trapping CO2 in the atmosphere, and converting the CO2 into organic carbon compounds through microorganisms or enzyme, (2), trapping CO2 in the atmosphere in a physical method, (3), trapping CO2 in the atmosphere in a chemical method, (4), trapping CO2 in the atmosphere in a physicochemical method, and (5), carrying out carbon storage and sealing storage on the carbon resources trapped from the atmosphere to achieve negative growth of atmospheric CO2, reduce partial pressure of atmospheric CO2 gas, adjust the greenhouse effect and solve relevant environmental problems, putting the stored carbon products into global carbon trading, and carrying out technical control over the cyclic process of carbon cycle, carbon conversion, carbon storage, carbon sealing storage and carbon utilization so that people can use carbon sources fully and reasonably. Manual cultivation and planting of the rank vegetation are new power for carbon cycles on the earth.

Description

technical field [0001] The invention relates to a device and a method for capturing carbon resources in the atmosphere, belonging to the field of resources and environment. Background technique [0002] Since the 18th century, due to the extensive use of coal, oil, and natural gas, the CO emitted by humans into the atmosphere 2 As greenhouse gases increase year by year, the greenhouse effect will increase, causing sea level rise; abnormal climate, increased ocean storms; land drought, reduced grain production; rapidly expanding desertification area; diseases, insects, pests, heat stroke and infectious diseases on the earth Frequent and other serious natural disasters. The greenhouse effect and global warming have attracted widespread attention and great attention from all countries in the world. global CO emissions into the atmosphere each year 2 About up to 200×10 8 t above. Human emissions of CO into the atmosphere 2 The annual rate of 3%~5% is increasing, which has ...
