Abstract
Description
Technical Field
[0001] This utility model relates to intelligent carbon reduction equipment in power systems, specifically to a carbon capture and purification device. Background Technology
[0002] Against the backdrop of global climate change, carbon dioxide emissions have become a key factor restricting business development and environmental protection. In particular, the control of carbon emissions has long been a global concern, with global carbon emissions continuing to rise. In recent years, both internationally and domestically, efforts to address the threat of global warming have been intensified to control carbon emissions.
[0003] Existing technologies have incorporated intelligent carbon reduction and other functions into new power systems. However, the following problems still exist:
[0004] 1. Grid connection loss between wind and solar power: Current distributed photovoltaic / wind power requires multiple energy conversion stages: "DC (direct current) → AC (alternating current) inverter → boost → high voltage transmission → buck → AC". The overall efficiency is only 78%, with line losses of 6%-8%. For 100 kWh, about 22 kWh is wasted in the form of Joule heat during the process, which is equivalent to an additional emission of 18.6 kg CO2.
[0005] 2. Thermal power plants need to make adjustments and store energy reserves when wind and solar power are insufficient. The combination of wind, solar, thermal and energy storage leads to a rebound in carbon emissions. The volatility of wind and solar power reduces the annual utilization hours of coal-fired power plants from 5,000 hours to 3,000 hours. Frequent start-ups and shutdowns of units lead to an increase in coal consumption of 8%-12%, resulting in the abnormal phenomenon that "the more wind and solar power there is, the more the carbon emission curve drops and then rises."
[0006] 3. CCUS (Carbon Capture, Utilization and Storage) technology has high barriers to entry. A million-ton-level CCUS system costs 3,000-5,000 yuan / tCO2 in CAPEX. It requires a large area and is complex to operate and maintain, which is difficult for small and micro entities to afford. Moreover, most of them are centralized and cannot be adapted to the distributed needs of campuses, industrial parks and other places.
[0007] 4. The air purification and carbon sequestration functions are separated. Commercially available air purifiers can only filter PM2.5 and do not have CO2 capture function; while existing DAC (direct air capture, carbon dioxide negative emission technology) equipment lacks synergistic effects such as air purification and plant enhancement, resulting in "two sets of equipment and double energy consumption".
[0008] 5. Poor versatility of structural components and high maintenance costs. DAC reaction chambers are mostly made of metal welding or injection molding, which are large in size and heavy in weight. Filter replacement requires special tools, and maintenance time is >2 hours, making it difficult to iterate quickly. Utility Model Content
[0009] To address the problems existing in the prior art, this utility model provides a carbon capture and purification device that combines a negative ion generator with a carbon capture box, integrating air purification and carbon fixation functions into one unit. It also features good structural versatility and low maintenance costs.
[0010] The technical solution of this utility model is: a carbon capture and purification device, including an air inlet, an air inlet air quality sensor, a dust removal chamber, a negative oxygen ion generator, a top cover, a fan, an air duct, a carbon capture chamber, a carbon capture box, an air outlet, and an air outlet air quality sensor.
[0011] The air quality sensor at the air inlet is fixedly installed at the air inlet; the air inlet is fixedly installed at the opening on one side of the dust removal chamber; the negative ion generator is placed inside the dust removal chamber;
[0012] The top cover is fixed to the top opening of the dust removal chamber, and the top cover has an opening;
[0013] The air quality sensor at the air outlet is fixedly installed at the air outlet; the air outlet is installed at the opening on one side of the horizontally placed carbon capture chamber, and the air outlet of the air duct is integrally fixedly connected to the opening on the other side of the carbon capture chamber.
[0014] The carbon-catching chamber is equipped with the carbon-catching box, and the carbon-catching box contains food-grade Ca(OH)2.
[0015] The air inlet of the air duct faces downward, and the air outlet side of the fan is fixedly installed at the air inlet of the air duct; the air inlet side of the fan is connected and fixed to the opening on the upper cover.
[0016] Furthermore, the air outlet and the opening on one side of the carbon capture chamber are detachably connected via a magnetic snap-fit. The carbon capture box is detachably installed inside the carbon capture chamber via a magnetic snap-fit. The structures of the carbon capture chamber, carbon capture box, and air outlet are all 3D printed from carbon fiber reinforced polylactic acid in a single step. This facilitates maintenance; the carbon capture box can be replaced in 5 seconds. The weight of a single part is less than 180g, representing a 65% reduction in weight and a 42% reduction in cost compared to aluminum alloy solutions. Maintenance time is reduced from 2 hours to 5 minutes, supporting rapid iteration.
[0017] Furthermore, the top cover is snap-fitted onto the top opening of the dust collection chamber. It is easy to assemble and disassemble.
[0018] Furthermore, it includes a PWM wind-solar hybrid controller, the input of which can be connected to a wind power generation device and a solar power generation device to receive electrical energy transmitted by the wind power generation device or the solar power generation device.
[0019] The PWM / solar hybrid controller has three output channels: the first connects to the battery; the second connects in series with an air switch and a relay, then to the negative ion generator and the fan; the third directly connects to drive the inlet air quality sensor, the outlet air quality sensor, and a serial server for collecting data from these sensors and transmitting it to the carbon capture and purification device controller. This allows the device to use a 12V–36V DC bus, directly connecting the 20W photovoltaic power and 15W wind power to the load. After the solar panels generate electricity, the inverter, boost converter, and grid connection are bypassed. The PWM / solar hybrid controller directly drives the fan, sensors, and serial server of the carbon capture and purification device. The device itself is equipped with a rechargeable power supply, which charges the battery when wind and solar power generation is sufficient, and uses battery power when wind and solar power are insufficient. Achieving a link efficiency of 94.2%; with short cable length and line loss of less than 0.5%, it reduces the 22% energy waste and hidden carbon emissions caused by traditional "wind and solar grid connection" from the source.
[0020] Furthermore, the air quality sensors at the air inlet and outlet are air quality detection chips capable of collecting CO2, PM2.5, and temperature and humidity data. The carbon capture and purification device controller collects real-time data on carbon dioxide detected by the air quality sensors at the air inlet. When the carbon dioxide level exceeds the threshold of 650 ppm, the carbon capture and purification device automatically activates. When wind and solar power are in surplus, electrical energy is stored in batteries to ensure 24-hour operation. When wind and solar power are insufficient, thermal power generation requires adjustments. This strategy further reduces carbon emissions while maintaining the same annual utilization hours of coal-fired power plants, resulting in a further 8%-12% reduction in net carbon emissions for the system.
[0021] Furthermore, the negative oxygen ion generator is -22 kV and can generate 2.1 × 10⁻⁶ ions. 4 This negative ion generator boasts ions / cm³ of negative oxygen ions. It simultaneously ionizes airborne dust, reducing PM2.5 levels. It removes up to 93% of PM2.5 and increases cucumber photosynthetic efficiency by 10% and root vitality by 20%. A single device can simultaneously perform carbon sequestration, air purification, and plant enhancement, eliminating the need for secondary investment.
[0022] Furthermore, the carbon capture box has a volume of 120 mL and contains 100 g of food-grade Ca(OH)2. By placing 100 g of food-grade Ca(OH)2 in a 3D-printed carbon capture box of only 120 mL, and enhancing mass transfer through negative ion wind, the reaction rate constant k is increased from 0.12 min⁻¹ to 0.31 min⁻¹. Experiments show that CO2 emissions can be reduced from 1406 ppm to 441 ppm within 30 minutes, with an average daily carbon capture of 1.15 kg and an annual CO2 reduction of 0.42 t CO2; the CAPEX is reduced to <1200 yuan / t CO2, only one-third of that of traditional methods.
[0023] Furthermore, the carbon capture chamber, carbon capture box, and air outlet are all constructed from carbon fiber reinforced polylactic acid through a one-time 3D printing process.
[0024] The beneficial effects of this utility model are: it provides a carbon capture and purification device that combines a negative oxygen ion generator with a carbon capture box, integrating air purification and carbon fixation functions into one, and has good structural versatility and low maintenance costs.

Detailed Implementation
[0032] The present invention will be further described below with reference to the accompanying drawings.
[0033] like Figure 1 , 2As shown, a carbon capture and purification device includes an air inlet 1, an air inlet air quality sensor 2, a dust removal chamber 3, a negative oxygen ion generator 4, a top cover 5, a fan 6, an air duct 7, a carbon capture chamber 8, a carbon capture box 9, an air outlet 10, and an air outlet air quality sensor 11.
[0034] The air quality sensor 2 is fixedly installed at the air inlet 1. The air inlet 1 is fixedly installed at the opening on one side of the dust collection chamber 3. The negative ion generator 4 is placed inside the dust collection chamber 3.
[0035] The upper cover 5 is fixed to the top opening of the dust removal chamber 3, and the upper cover 5 has an opening.
[0036] The air quality sensor 11 is fixedly installed at the air outlet 10. The air outlet 10 is installed at one side opening of the horizontally placed carbon capture chamber 8, and the air outlet and the side opening of the carbon capture chamber 8 are detachably connected by a magnetic snap-fit. The air outlet of the air duct 7 is integrally fixedly connected to the other side opening of the carbon capture chamber 8. The carbon capture box 9 is detachably installed inside the carbon capture chamber 8 by a magnetic snap-fit. The carbon capture box 9 contains food-grade Ca(OH)2. The structures of the carbon capture chamber 8, the carbon capture box 9, and the air outlet 10 are all 3D printed from carbon fiber reinforced polylactic acid in one piece. Maintenance is convenient; the detachable magnetic snap-fit connection allows for carbon capture box replacement in 5 seconds. The weight of a single piece is <180 g, which is 65% lighter and 42% cheaper than the aluminum alloy solution, reducing maintenance time from 2 hours to 5 minutes, and supporting rapid iteration.
[0037] The air inlet of the air duct 7 faces downward, and the air outlet side of the fan 6 is fixedly installed at the air inlet of the air duct 7. The air inlet side of the fan 6 is connected and fixed to the opening on the upper cover 5.
[0038] The top cover 5 is snapped onto the top opening of the dust collection chamber 3. It is easy to assemble and disassemble.
[0039] like Figure 3 As shown, a carbon capture and purification device also includes a PWM wind-solar hybrid controller, the input of which can be connected to a wind power generation device and a solar power generation device to receive electrical energy transmitted by the wind power generation device or the solar power generation device.
[0040] The output of the PWM wind-solar hybrid controller is divided into three paths: the first path is connected to the battery. For example... Figure 4 As shown, the second circuit connects the air switch and relay in series to the negative ion generator 4 and the fan 6. Figure 5As shown, the third channel directly connects to drive the inlet air quality sensor 2, the outlet air quality sensor 11, and a serial server for collecting data from the inlet air quality sensor 2 and the outlet air quality sensor 11 and transmitting it to the carbon capture and purification device controller, as shown. Figure 6 As shown, this allows the device to use a 12V–36V DC bus to directly connect the DC power generated by the 20W photovoltaic system and the 15W micro-wind system to the load. For example... Figure 3 As shown, after the solar panels generate electricity, the process skips the inverter, boost, and grid connection stages. The PWM wind-solar hybrid controller directly drives the wind turbine, sensors, and serial server of the carbon capture and purification device. The equipment itself is equipped with a rechargeable power supply, charging the device's battery when wind and solar power generation is sufficient, and using battery power when wind and solar power are insufficient. This achieves a link efficiency of 94.2%. The short cable length and line loss of less than 0.5% eliminate the 22% energy waste and hidden carbon emissions caused by traditional wind-solar grid connection at the source.
[0041] The inlet air quality sensor 2 and the outlet air quality sensor 11 are air quality detection chips capable of collecting CO2, PM2.5, and temperature and humidity data. The carbon capture and purification device controller collects real-time data on carbon dioxide detected by the inlet air quality sensor. When the carbon dioxide level exceeds the threshold of 650 ppm, the carbon capture and purification device automatically activates. When wind and solar power are in surplus, electrical energy is stored in batteries to ensure 24-hour operation. When wind and solar power are insufficient, thermal power needs to be allocated. This strategy further reduces carbon emissions while maintaining the same annual utilization hours of coal-fired power plants, resulting in a further 8%-12% reduction in the system's net carbon emissions.
[0042] The negative oxygen ion generator 4 is -22 kV and can generate 2.1 × 10⁻⁶ ions. 4 This negative ion generator boasts ions / cm³ of negative oxygen ions. It simultaneously removes up to 93% of PM2.5 and increases cucumber photosynthetic efficiency by 10% and root vitality by 20%. A single device can simultaneously perform carbon sequestration, air purification, and plant enhancement, eliminating the need for secondary investment.
[0043] The carbon capture box 9 has a volume of 120 mL and contains 100 g of food-grade Ca(OH)2. By placing 100 g of food-grade Ca(OH)2 in a 3D-printed carbon capture box of only 120 mL, and enhancing mass transfer through negative oxygen ion wind, the reaction rate constant k was increased from 0.12 min⁻¹ to 0.31 min⁻¹. Experiments show that CO2 emissions can be reduced from 1406 ppm to 441 ppm within 30 minutes, with an average daily carbon capture of 1.15 kg and an annual CO2 reduction of 0.42 t CO2; the CAPEX is reduced to <1200 yuan / t CO2, only one-third of that of traditional methods.
[0044] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
