Description

Technical Field

[0001] This invention relates to the field of carbon absorption technology, and in particular to a modular carbon absorption device and application method adaptable to multiple scenarios. Background Technology

[0002] As micro-units of low-carbon cities, campuses exhibit three main characteristics in carbon emissions: dispersion, fluctuation, and spatial constraints. Carbon sources primarily originate from gas combustion in canteens, small heating equipment in laboratories, and air conditioning systems in dormitories and teaching buildings, with no centralized large-scale carbon sources. Carbon emissions surge during canteen mealtimes; laboratory carbon emissions fluctuate with experimental schedules. Core carbon source areas such as laboratory countertops, canteen kitchens, and teaching building corridors have limited space, making it impossible to accommodate large-scale industrial-grade carbon absorption equipment. Mainstream solutions, such as campus green walls or green belts, rely on natural absorption through plant photosynthesis, achieving only 20%-30% removal efficiency, and are limited by light and space constraints. Simplified industrial water-washing carbon absorption devices use clean water as the absorption medium, resulting in low CO2 solubility and an absorption efficiency of less than 40%; furthermore, continuous electric heating regeneration is required, consuming 8%-10% of the total energy consumption of small campus equipment, which is inconsistent with the low-carbon campus concept. The most significant technical problems with existing campus carbon absorption technologies are poor adaptability, low efficiency, and high energy and maintenance costs, failing to meet the needs of multi-source, decentralized carbon emission scenarios on campuses. Summary of the Invention

[0003] The purpose of this invention is to provide a modular carbon absorption device and application method adaptable to multiple scenarios. Through modular design, composite absorption medium, low-energy regeneration and intelligent monitoring, it solves the unique problems of carbon absorption.

[0004] To achieve the above objectives, the present invention provides a multi-scenario adaptable modular carbon absorption device, including a carbon capture unit, a low-energy regeneration module, a scenario adaptation interface module, and a monitoring and control module. The monitoring and control module is connected to the carbon capture unit via a flexible hose, and the carbon capture unit is connected to the low-energy regeneration module and the scenario adaptation interface module via flexible hoses. Both the scenario adaptation interface module and the low-energy regeneration module are connected to the monitoring and control module.

[0005] Preferably, the monitoring and control module includes a logistics communication module and dual CO2 sensors, the dual CO2 sensors are connected to an air inlet and an air outlet, and the monitoring and control module is externally equipped with an operation panel.

[0006] Preferably, the scenario adaptation interface module includes a unit splicing hose and an air intake pipe interface, wherein multiple air intake pipe interfaces are provided, and multiple air intake pipe interfaces are connected to an exhaust pipe.

[0007] Preferably, the low-energy regeneration module includes a waste heat exchanger and a temperature controller. The temperature controller controls the temperature inside the device to be between 60 and 70 degrees Celsius. The temperature controller is located at the lower part of the waste heat exchanger, and the waste heat exchanger is connected to the flue pipe and the waste heat pipeline.

[0008] Preferably, the low-energy regeneration module is provided with a CO2 collection port at its end, and the CO2 collection port is optionally equipped with a small gas bag.

The adjustable silent fan is located at the lower part of the carbon capture unit, and an exhaust port is provided at the upper part of the carbon capture unit. The exhaust port is located at the upper part of the composite medium layer.

[0010] Preferably, the composite medium layer includes a modified activated carbon layer and a peat moss layer, both of which are disposed inside a pull-out drawer, and the drawer is provided with a leak-proof drainage channel on its exterior.

[0011] Preferably, the carbon capture unit adopts a standard unit size, and the carbon capture unit adopts single connection and parallel connection.

[0012] The method of using a multi-scenario adaptable modular carbon absorption device includes the following steps: Step 1: Scene adaptation. Select the appropriate connector in the scene adaptation interface module, connect the pipeline, and connect the two modular carbon capture units in parallel through the splicing hose; operate the intelligent module. Step 2, carbon absorption process: The generated CO2-containing airflow enters the carbon capture unit through the scene adaptation interface module. The adjustable speed silent fan blows the airflow evenly to the composite medium layer. The upper modified activated carbon layer quickly adsorbs CO2, and the lower peat moss layer assists in adsorbing and filtering a small amount of particulate matter. After purification, the airflow is discharged from the exhaust port. Step 3: Intelligent monitoring. Dual CO2 sensors detect the concentration at the inlet and outlet in real time, calculate the absorption efficiency, and upload the data synchronously to the campus logistics APP. Step 4: Low-energy regeneration reduces carbon emissions to below 2000ppm. The monitoring and control module automatically switches to regeneration mode. The waste heat exchanger heats the hot gas flow to 70°C and then introduces it into the carbon capture unit. CO2 in the composite medium is desorbed. After regeneration, the medium regains its adsorption capacity, and the device automatically switches back to standby mode.

[0013] Preferably, when the absorption efficiency is below 70% for 3 consecutive hours, the monitoring and control module pushes a media replacement reminder to the logistics APP.

[0014] Therefore, this invention adopts the aforementioned multi-scenario adaptable modular carbon absorption device and application method, which has strong scenario adaptability. Its modular design with multiple interfaces can cover all scenarios, including canteens, laboratories, and teaching buildings, overcoming the shortcomings of fixed size and space limitations. It boasts high and stable absorption efficiency, with composite media efficiency far exceeding that of green walls and water washing devices.

[0019] Example Please see Figure 1This invention provides a modular carbon capture device adaptable to various scenarios, including a carbon capture unit 1, a low-energy regeneration module 2, a scenario adaptation interface module 3, and a monitoring and control module 4. The monitoring and control module 4 is connected to the carbon capture unit 1 via a flexible hose 5. The carbon capture unit 1 is also connected to the low-energy regeneration module 2 and the scenario adaptation interface module 3 via flexible hose 5. Both the scenario adaptation interface module 3 and the low-energy regeneration module 2 are connected to the monitoring and control module 4. The flexible hose 5 is a DN100 PVC pipe, and the flexible hose 5 is connected to the module unit via a snap-fit ​​connection. The modular unit adopts a standard size of 1.0m × 0.5m × 0.8m. Each unit supports independent and combined operation, and supports single-unit and multi-unit parallel operation. It is adaptable to high-flow scenarios in canteens and low-flow scenarios in laboratories, solving the problem of irregular campus spaces.

[0020] The monitoring and control module 4 is equipped with a logistics communication module and dual CO2 sensors. The dual CO2 sensors are connected to the air inlet and outlet, with a detection range of 0-5000ppm. The monitoring and control module 4 is equipped with an operation panel 6 on the outside. The operation panel 6 displays information such as CO2 concentration, flow rate, and temperature. It also includes a mode switching key and a start / stop control key. The operation panel 6 has a one-button switch between canteen mode and laboratory mode, which is convenient for logistics personnel to operate.

[0021] The scene adaptation interface module 3 includes a unit splicing hose and an air inlet interface 7. The air inlet interface 7 has multiple lengths, including 2cm, 8cm, and 10cm. Multiple air inlet interfaces are connected to the exhaust pipe. The scene adaptation interface module is equipped with an infrared detector. The unit splicing hose is 1-2m long and the unit spacing can be flexibly adjusted to adapt to irregular spaces on campus.

[0022] The low-energy regeneration module 2 includes a waste heat exchanger 8 and a temperature controller 9. The temperature controller 9 maintains the internal temperature at 60-70 degrees Celsius to prevent damage to the peat moss from high temperatures. The temperature controller 9 is located at the lower part of the waste heat exchanger 8, which is connected to the flue pipe and waste heat pipeline. The heat exchange area is 0.5 m². 2 Titanium is corrosion-resistant. The waste heat exchanger 8 is connected to the exhaust gas from the canteen or the waste heat from the air conditioning in the teaching building, reducing energy consumption by more than 60% and eliminating the need for additional electric heating, which aligns with the concept of a low-carbon campus; the temperature is controlled at 60-70℃ to avoid damage to the medium.

[0023] The low-energy regeneration module 2 is equipped with a CO2 collection port 10 at its end. The CO2 collection port 10 is equipped with a small gas bag for campus carbon emission reduction data statistics.

[0024] The carbon capture unit 1 includes a composite absorption medium layer and an adjustable silent fan with a flow rate of 0.5-12 m³ / h. 3 / h, noise ≤45dB, adjustable silent fan is located at the lower part of carbon capture unit 1, and exhaust port 11 is provided at the upper part of carbon capture unit 1, and exhaust port 11 is located at the upper part of composite medium layer.

[0025] The composite media layer comprises a modified activated carbon layer 12 and a peat moss layer 13, each 8cm thick. The combination of modified activated carbon and peat moss achieves an adsorption efficiency of ≥80%, and ≥75% under low temperature or low light conditions. It is non-corrosive and non-toxic, while the peat moss contributes to the aesthetics of campus landscaping. Both the peat moss layer 13 and the modified activated carbon layer 12 are housed in a pull-out drawer for easy replacement of the composite media layer. The drawer exterior features a leak-proof drainage channel to prevent condensate leakage during regeneration from damaging campus equipment. Dual CO2 sensors and a logistics APP link extend the media replacement cycle to 15-20 days, reducing maintenance costs.

[0026] The method of using a multi-scenario adaptable modular carbon absorption device includes the following steps: Step 1: Scene adaptation. Select the appropriate connector in the scene adaptation interface module 3, connect the pipeline, and connect the two modular carbon capture units 1 in parallel through the splicing hose 5; operate the intelligent module.

[0027] Step 2, carbon absorption process: The generated CO2-containing airflow enters the carbon capture unit 1 through the scene adaptation interface module 3. The adjustable speed silent fan blows the airflow evenly to the composite medium layer. The upper modified activated carbon layer 12 quickly adsorbs CO2, and the lower peat moss layer 13 assists in adsorbing and filtering a small amount of particulate matter. After purification, the airflow is discharged from the exhaust port 11.

[0028] Step 3: Intelligent monitoring. Dual CO2 sensors detect the concentration at the inlet and outlet in real time, calculate the absorption efficiency, and upload the data synchronously to the campus logistics APP.

[0029] Step 4: Low-energy regeneration, carbon emissions are reduced to below 2000ppm. The monitoring and control module 4 automatically switches to regeneration mode. The waste heat exchanger 8 heats the hot airflow to 70℃ and then introduces it into the carbon capture unit 1. CO2 in the composite medium is desorbed. After regeneration is completed, the medium restores its adsorption capacity, and the device automatically switches back to standby mode.

[0030] If the absorption efficiency is below 70% for 3 consecutive hours, the monitoring and control module 4 will push a media replacement reminder to the logistics APP.

[0031] Taking a high-traffic scenario like a cafeteria during mealtimes as an example, the specific steps are as follows: Step 1: Scene Adaptation. Select the 10cm connector in scene adaptation interface module 3 and connect it to the canteen exhaust pipe. Connect the two modular carbon capture units 1 in parallel via the splicing hose 5 to handle high flow rates during mealtimes. Operate the intelligent module to switch to canteen mode with one click, and the fan will automatically adjust to 10m. 3 / h, regeneration temperature set to 70℃.

[0032] Step 2: Carbon Absorption Process. The CO2-containing flue gas generated by the combustion of gas in the canteen has a concentration of approximately 3000-4000 ppm. It enters the carbon capture unit 1 through the scene adaptation interface module 3. The adjustable speed fan blows the flue gas evenly onto the composite medium layer. The upper modified activated carbon layer 12 is loaded with carbonic anhydrase to quickly adsorb CO2. The lower peat moss layer 13 assists in adsorbing and filtering a small amount of particulate matter in the flue gas. After purification, the CO2 concentration of the flue gas is reduced to 600-800 ppm, which meets the indoor air quality standards, and it is discharged from the top.

[0033] Step 3: Intelligent monitoring. Dual CO2 sensors detect the concentration at the inlet (3500ppm) and outlet (700ppm) in real time, calculate the absorption efficiency, and display it on the operation panel 6. The data is also uploaded to the campus logistics APP, which logistics personnel can view remotely.

[0034] Step 4: Low-energy regeneration. After mealtimes, carbon emissions drop below 2000 ppm, and monitoring and control module 4 automatically switches to regeneration mode. Waste heat exchanger 8 connects to the waste heat from the canteen's exhaust, at approximately 120°C. The hot airflow is heated to 70°C and then introduced into carbon capture unit 1. CO2 in the composite medium is desorbed, and the desorbed gas can be collected in a gas bag for campus carbon reduction statistics. After regeneration, the medium regains its adsorption capacity, and the device automatically switches back to standby mode. When the absorption efficiency is below 70% for three consecutive hours, monitoring and control module 4 pushes a medium replacement reminder to the logistics APP. Logistics personnel manually remove the old medium layer and insert the new one.

[0035] Modified activated carbon and peat moss can be replaced with molecular sieves and sphagnum moss. Molecular sieves increase adsorption capacity by 10% and efficiency by ≥85%, but cost increases by 15%, making them suitable for laboratories with high requirements for absorption efficiency.

[0036] The waste heat from the canteen can be replaced with solar collectors, eliminating the need for waste heat and making it suitable for campuses with ample sunlight. However, the regeneration efficiency is affected by the weather, and on cloudy or rainy days, auxiliary electric heating is required, increasing energy consumption by 10%.

[0037] The outer shell, made of PP plastic, can be replaced with 304 stainless steel, which improves the temperature resistance to 100℃, making it suitable for high-temperature exhaust scenarios in laboratories. However, the weight increases by 30%, making it more suitable for fixed installation scenarios.

[0038] Therefore, this invention adopts the aforementioned multi-scenario adaptable modular carbon absorption device and application method, which has strong scenario adaptability. Its modular design with multiple interfaces can cover all scenarios, including canteens, laboratories, and teaching buildings, overcoming the shortcomings of fixed size and space limitations. It boasts high and stable absorption efficiency, with composite media efficiency far exceeding that of green walls and water washing devices. Energy consumption and maintenance costs are low, with reduced energy consumption for waste heat regeneration, extended media replacement cycles, and lower maintenance costs. It balances campus safety and aesthetics, with a leak-proof design to prevent equipment damage, no toxic media, and an appearance that matches the campus color scheme.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
