[0024] For ease of understanding, the five core modules will now be explained in detail.
[0025] The industrial emission source module 110 is used to monitor flue gas data and perform prediction and data processing.
[0026] In some embodiments, such as Figure 2 As shown, the industrial emission source module 110 includes a real-time monitoring unit 111, an operating condition prediction unit 112, and a data preprocessing unit 113.
[0027] The real-time monitoring unit 111 includes multiple sensor arrays for collecting flue gas data, including flow rate data, concentration data, content data, and temperature data. For example, multi-parameter sensor arrays are installed at the outlets of emission sources such as cement kilns, coal / gas boilers, and steel sintering machines to collect real-time flue gas flow rate, CO2 concentration, temperature, and SO2 / NO2 ratio. x Data such as content and dust concentration.

[0033] The multi-stage synergistic purification unit 121 is used for graded purification of flue gas. For example, the multi-stage synergistic purification unit 121 includes a first purification unit, a second purification unit, and a third purification unit connected in sequence. The first purification unit is a primary dust removal stage, specifically employing a high-efficiency bag filter to reduce the dust content to 5 mg / Nm³. 3 Within [a certain range].

The third stage uses a metal fiber filter with high filtration accuracy, preventing clogging of heat exchange equipment and ensuring uniform carbonization reaction. The units are sequentially connected, with a simple process flow. Parameters can be dynamically adjusted according to flue gas conditions, improving purification efficiency and reducing energy consumption.
[0034] The dynamic conditioning buffer tank 122 is connected to the multi-stage synergistic purification unit 121. Exemplarily, the dynamic conditioning buffer tank 122 adopts an innovative three-section buffer design, including an intake homogenization zone, a conditioning reaction zone, and a stable output zone. The conditioning system of the dynamic conditioning buffer tank 122 includes a spray device, a multi-stage heating coil, and an ultrasonic atomizing humidifier.

[0039] Waste heat recovery unit 131 is used to capture waste heat in stages according to flue gas temperature.

The second temperature section is a medium-temperature section (120℃-180℃), including 180℃ and 120℃, specifically generating 90℃-120℃ hot water through a flue gas heat exchanger for heat preservation in the carbonization curing furnace. The third temperature section is a low-temperature section (80℃-120℃), including 80℃ but excluding 120℃, specifically generating 60℃-90℃ hot water through a hot water heat exchanger for heating the plant area and pre-treatment of the boards. By dividing waste heat into three segments based on temperature for precise utilization: the high-temperature segment produces steam for board drying, the medium-temperature segment produces hot water for curing furnace insulation, and the low-temperature segment produces hot water for heating and pretreatment, achieving efficient utilization of waste heat across all scenarios. This segmented design facilitates equipment selection and parameter matching, improves recovery efficiency, avoids heat waste, stabilizes process parameters, and enhances product quality.

[0042] In this embodiment, the waste heat recovery unit 131 captures waste heat in stages according to flue gas temperature, achieving efficient utilization in stages, reducing heat waste, and improving energy efficiency. The heat storage buffer unit 132 uses phase change heat storage materials to store excess waste heat, solving the time mismatch between waste heat and heat demand, and ensuring continuous and stable heating. The intelligent heat network distribution unit 133, based on model predictive control algorithms, dynamically adjusts the heat distribution according to the needs of each process section, achieving precise heating. The three work together to form a closed-loop heat energy utilization chain of "waste heat recovery - heat storage buffer - precise distribution," providing stable and efficient heat energy support for the production of carbon mineralized panels. The carbon mineralization board production line adapter module 140 is connected to the waste heat recovery and distribution module 130 for production line equipment modification and adaptation, carbonization curing and board conveying control.

[0044] The carbonization curing furnace 142 adopts an innovative design, featuring multi-point air intake at the bottom and swirling air outlet at the top to improve the uniformity of CO2 distribution and optimize airflow organization; the furnace chamber is divided into 3-5 control zones with zoned temperature and humidity control to achieve gradient curing; and CO2 concentration distribution monitoring, plate surface temperature monitoring, and reaction process monitoring are added.
[0045] The sheet material conveying unit 143 is equipped with a radio frequency identification system, that is, an RFID tagging system, to realize the whole process tracking of the sheet material; for example, the sheet material conveying unit 143 is also equipped with an automatic scheduling system to optimize the furnace entry and exit scheduling according to the curing status.
[0046] In this embodiment, the vertical drying oven 141 is equipped with a steam-air heat exchanger, which efficiently utilizes waste heat steam, improves drying uniformity, and reduces drying energy consumption. The carbonization curing oven adopts a bottom multi-point air inlet and top swirl air outlet structure to improve CO2 distribution uniformity, making the carbonization reaction more complete and increasing the carbon solidification amount and strength of the board. The board conveying unit integrates an RFID system to achieve full-process tracking and quality traceability, providing data support for production scheduling and carbon solidification accounting. Each unit is coordinated to adapt to flue gas and waste heat utilization requirements, deeply coupled with the system, improving the level of intelligence and production efficiency.

The carbon cycle traceability module 160's cycle verification algorithm is as follows: unit product carbon sequestration amount = (consumed flue gas volume × average CO2 concentration × solidification efficiency coefficient) / product output; system energy efficiency index = (waste heat utilization + carbon solidification equivalent emission reduction) / total system energy consumption. Through the full-process carbon metering and carbon label generation system, a verifiable closed-loop verification system of "industrial carbon emissions → building material storage" is established.
