[0027] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.

[0028] like Figure 1 and Figure 2 As shown, this application provides a small, portable carbonization device that utilizes industrial carbon dioxide exhaust gas, including an air intake system 01, an exhaust system 02, a water removal system 03, a monitoring system 04, a uniform gas distribution system 05, and a drainage system 06.

[0029] The water removal system 03 of this application includes a water removal tank 1, in which a Pall ring is installed to reduce the water content in the carbon dioxide-containing exhaust gas from the flue gas source (in this embodiment, the flue gas source is a chimney, but the flue gas source is not limited to a chimney), thereby reducing the impact of excessive water content on the carbonization process.

[0030] The inlet of the dewatering tank is located at the bottom, and the outlet is located at the top. Flue gas enters from the bottom and exits from the top. A first drain pipe with a first drain valve is also installed at the bottom of the dewatering tank. The flue gas source 7 is connected to the inlet of the dewatering tank via a first pipe 8. The filtered water collects at the bottom of the dewatering tank and is discharged through the first drain pipe. The filtered water is also collected, sampled, and tested.

[0031] The air intake system 01 of this application includes a blower and a first eddy current flow meter. The blower in this application is a Roots blower 2. The inlet of the blower is connected to the outlet of the dewatering tank through a second pipeline 9, and the outlet of the blower is connected to the air inlet of the uniform air distribution system through a third pipeline 10. The first eddy current flow meter is installed on the third pipeline near the air inlet of the uniform air distribution system. The flue gas in the flue gas source is drawn out from the outlet of the flue gas source by the suction of the Roots blower, passes through the dewatering tank, and enters the blower. The blower pressurizes the flue gas before it enters the movable carbonization box, providing the movable carbonization box with the required flow rate and pressure of flue gas.

[0032] The exhaust system 02 of this application includes a fourth pipe 11 and a second valve 5. The fourth pipe is connected to the exhaust port of the movable carbonization box and the flue gas source. The second valve is installed on the fourth pipe and is used to regulate the system pressure and device pressure relief.

[0033] The uniform gas distribution system 05 of this application includes a movable carbonization box 3, which is provided with an air inlet, an air outlet, and a detection port. The air inlet is connected to the outlet of a fan through a third pipeline, the air outlet is connected to a flue gas source through a fourth pipeline, and the detection port 6 is connected to a monitoring system through a fifth pipeline. The movable carbonization box is provided with a feed inlet, which is used to put in or take out the blank to be carbonized through the opening and closing of the feed door. A chamber is provided inside the movable carbonization box, and there is a gap between the chamber and the outer wall of the movable carbonization box. A DN5 aperture dot matrix is ​​evenly arranged on the chamber wall to make the gas distribution uniform. Multiple baffles are provided inside the movable carbonization box, and the edge of the baffle is 20cm away from the outer wall. φ5mm circular gas distribution holes are evenly distributed on the baffles to make the gas concentration inside the movable carbonization box uniform.

[0034] It also includes multiple stackable trays with a hollow structure. In this embodiment, the trays can be stacked up to 30 layers. The specific number can be determined as needed and does not affect the implementation of the technical solution of this application. The pressed and shaped slab to be carbonized is placed on the hollow tray, so that the slab to be carbonized can contact the flue gas to the maximum extent. The carbon dioxide in the flue gas is absorbed and reacted in the movable carbonization box. After the reaction is completed, the carbon dioxide concentration in the flue gas decreases. When it is lower than the set value, the second valve is opened, and the remaining flue gas is returned to the flue gas source through the fourth pipeline.

[0035] The drainage system 06 includes a sixth pipe and a second drain valve. The sixth pipe is connected to the movable carbonization box, and the second drain valve is installed on the sixth pipe to promptly remove accumulated water from the device.

[0036] The monitoring system 04 includes an inhalation monitor 4, a temperature and humidity combined detector, and a pressure gauge. The inhalation monitor is connected via a fifth pipeline to the air inlet, air outlet, and detection point of the movable carbonization chamber. A temperature and humidity combined detector and a pressure gauge are installed at both the air inlet and outlet of the movable carbonization chamber. The inhalation monitor is used to monitor carbon dioxide concentration, with a control range of 0-99% and an accuracy of ±1%. The temperature and humidity combined detector monitors the temperature and humidity within the system and outputs temperature and humidity curves. The physical pressure gauge provides real-time pressure feedback.

[0037] The inhalation detector is connected to the air inlet, air outlet and detection point of the movable carbonization chamber via a 6# PU air tube (the fifth line) to detect the gas inhaled at the detection point. The inhalation detector of this application is also connected to a centrifugal adsorption filter to reduce the influence of the moisture content of the flue gas on the monitoring results and to compare it with the carbon dioxide concentration at the air inlet.

[0038] When this technical solution is used in practice:

[0039] Flue gas is drawn from the outlet of the flue gas source by the suction of the Roots blower, and enters the dewatering tank through the DN150 first pipeline. The dewatering tank contains Pall rings; the inlet is located at the bottom and the outlet at the top, with the flue gas entering from the bottom and exiting from the top. As the flue gas passes through the Pall rings in the dewatering tank, the Pall rings filter out some of the moisture in the flue gas. The filtered moisture collects at the bottom of the dewatering tank, where a first drain pipe is connected. A drain valve is installed on the first drain pipe for draining moisture and for collecting, sampling, and testing the filtered moisture. After the flue gas has been dewatered, it is drawn into the inlet of the Roots blower and compressed and pressurized. The pressure inside the movable carbonization box can be adjusted to 0.06 MPa (the pressure inside the movable carbonization box is adjusted by changing the speed of the Roots blower and the opening of the second valve at the outlet of the movable carbonization box according to process requirements). The compressed flue gas enters the movable carbonization box through the first eddy current flow meter at the inlet of the movable carbonization box (to detect the flow rate at the inlet), and processes the slab inside the movable carbonization box. The inlet and outlet of the movable carbonization box are equipped with inlet and outlet chambers. The inner partition is 20 cm away from the outer wall and is evenly distributed with φ5 mm circular holes for gas distribution, so that the gas concentration inside the movable carbonization box is uniform. After being pressed and shaped, the slab is placed on a perforated tray (to maximize contact between the slab and the flue gas). The trays are stacked up to 30 layers high. The flue gas is absorbed and reacted in the movable carbonization chamber. After the reaction is complete, the carbon dioxide concentration in the flue gas decreases. Once it falls below a set value, the second valve is opened. The movable carbonization chamber is equipped with a carbon dioxide detector to detect the carbon dioxide concentration inside the chamber. Simultaneously, carbon dioxide detectors are also installed at the inlet and outlet of the carbonization chamber to compare data and determine the slab's carbon dioxide absorption capacity. The inlet and outlet of the movable carbonization chamber are also equipped with thermometers and hygrometers to detect the impact of different temperature and humidity conditions on the slab's carbon dioxide absorption efficiency. The Roots blower and the movable carbonization chamber are controlled by the first and second valves, enabling three operating modes:

[0040] ① Atmospheric pressure direct discharge: The first and second valves at the inlet and outlet of the movable carbonization box are fully open, and the valve between the flue gas source and the inlet of the Roots blower is open. After the flue gas enters the movable carbonization box, it is discharged directly. The flue gas is supplied in unlimited quantities and carbon dioxide in the flue gas is captured freely by the slab.

[0041] ② Pressurized direct discharge: The first and second valves at the air inlet of the movable carbonization box are fully open. The second valve is at a certain opening degree according to the pressure requirement inside the movable carbonization box. The valve between the flue gas outlet and the Roots blower inlet is open. The flue gas is compressed by the Roots blower and enters the movable carbonization box for compression and pressurization. At the same time, a small amount of flue gas is discharged. The flue gas is supplied in unlimited quantities. While relying on the slab to freely capture carbon dioxide in the flue gas, the external pressure is increased to accelerate the carbon dioxide absorption rate of the slab.

[0042] ③ Internal circulation: After pressurizing the movable carbonization box to the predetermined pressure requirement, close the first and second valves of the inlet and outlet, open the valve between the flue gas source and the inlet of the Roots blower, and open the valve on the connecting pipe between the Roots blower and the fourth pipeline to allow the flue gas to circulate internally.

Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
