Abstract
Description
Technical Field
[0001] This utility model relates to a carbon capture device for bulk carriers, and more particularly to a carbon capture device for bulk carriers applied in the shipbuilding field. Background Technology
[0002] During operation, bulk carriers burn fuel and produce a large amount of exhaust gas containing carbon dioxide. Direct emissions would exacerbate the greenhouse effect and would not meet environmental protection requirements.
[0003] Chinese utility model patent CN202222519511.7 discloses a device for capturing carbon dioxide from ship exhaust gas, comprising: a heat exchange tower for cooling the ship exhaust gas entering the heat exchange tower; and an absorption tower containing catalytic packing material to allow seawater entering the absorption tower to react with the ship exhaust gas entering the absorption tower; wherein the heat exchange tower and the absorption tower are connected; the ship exhaust gas is cooled by passing through the heat exchange tower before entering the absorption tower, and the carbon dioxide in it is absorbed by the seawater entering the absorption tower before being discharged from the absorption tower. The device utilizes carbonic anhydrase in the catalytic packing material to catalyze the hydration reaction of CO2 with seawater, eliminating the need for heating and regenerating the seawater, and the captured CO2 does not require liquefaction and storage, significantly reducing system energy consumption and volume; immobilizing the carbonic anhydrase on the packing material increases the mass transfer rate and reduces the overall volume of the absorption tower.
[0004] However, the carbon capture equipment mentioned above still has some shortcomings in use. When the treatment tank in the existing technology uses the treatment liquid to spray and treat the waste gas, the treatment liquid needs to be filtered to prevent the presence of large particulate impurities in the treatment liquid from affecting the treatment of the waste gas. However, in actual operation, the rising waste gas contains some dust, which can easily clog the filter plate after contacting the treatment liquid. The clogged filter plate can generally only be cleaned after the machine is stopped, which affects the waste gas treatment efficiency and treatment effect. Summary of the Invention
[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the filter plates in the treatment tank are easily clogged and difficult to clean.
[0006] To address the aforementioned problems, this utility model provides a carbon capture device for bulk carriers, comprising a capture unit connected to the hull, the capture unit including a recovery tank, an extraction tank, and a processing tank, the recovery tank, the extraction tank, and the processing tank being connected together, and further comprising:
[0007] The air inlet pipe is fixedly connected to the bottom of the treatment tank;
[0008] The spray box is rotatably connected to the treatment tank;
[0009] The nozzle is fixedly connected to the bottom of the spray box;
[0010] The conical filter box is rotatably connected in the treatment tank, and the conical filter box is located directly below the spray box and above the air inlet pipe;
[0011] The conical filter box has multiple sets of oblique holes, which are evenly distributed on the conical filter box.
[0012] In the aforementioned carbon capture device, the impurities that are blocked in the inclined holes are centrifugally ejected by the rotation of the conical filter plate.
[0013] As a further improvement of this application, a sealing plate is rotatably connected to the spray box, and an infusion pipe is fixedly connected to the side wall of the treatment tank. The infusion pipe is fixedly connected to the sealing plate and is connected to the spray box.
[0014] As a further improvement of this application, a drive motor is fixedly connected to the top of the treatment tank, and a drive rod is fixedly connected to the drive end of the drive motor. The conical filter box and the spray box are both fixedly connected to the drive rod.
[0015] As a further improvement of this application, multiple sets of stirring rods are fixedly connected to the bottom side wall of the drive rod, and the multiple sets of stirring rods are evenly distributed on the drive rod.
[0016] As a further improvement of this application, a sealing ring is fixedly connected to the side wall of the conical filter box, and the sealing ring abuts against the inner side wall of the treatment tank.
[0017] As a further improvement to this application, a baffle is fixedly connected to the conical filter box.
[0018] As a further improvement to this application, the baffle is an arc-shaped plate.
[0019] In summary, this application uses a drive motor to rotate the spray box, which causes the spray nozzles to spray the treatment liquid evenly, allowing the treatment liquid to fully and evenly contact the exhaust gas, effectively improving the treatment efficiency and effect of the exhaust gas during carbon capture and enhancing the absorption capacity of carbon dioxide. At the same time, the drive rod synchronously drives the conical filter box to rotate, and under centrifugal force, impurities in the inclined holes are thrown out. Combined with the inclined hole design, the risk of clogging of the inclined holes is effectively reduced, the frequency of manual cleaning is reduced, and the continuous and stable filtration function is ensured.

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0028] Implementation method 1:
[0029] Figures 1-5 A carbon capture device for a bulk carrier is shown, including a capture unit 1 connected to the hull. The capture unit 1 includes a recovery tank 101, an extraction tank 102, and a treatment tank 103, which are connected by pipes. The device also includes: an air inlet pipe 1031 fixedly connected to the bottom of the treatment tank 103; a spray box 4 rotatably connected to the treatment tank 103; a nozzle 4011 fixedly connected to the bottom of the spray box 4; and a conical filter box 5 rotatably connected to the treatment tank 103, located directly below the spray box 4 and above the air inlet pipe 1031. The conical filter box 5 has multiple sets of oblique holes 503 evenly distributed on it.
[0030] A sealing plate 401 is rotatably connected to the spray box 4, and an infusion pipe 3 is fixedly connected to the side wall of the treatment tank 103. The infusion pipe 3 is fixedly connected to the sealing plate 401 and is connected to the spray box 4.
[0031] A drive motor 2 is fixedly connected to the top of the treatment tank 103. A drive rod 201 is fixedly connected to the drive end of the drive motor 2. The conical filter box 5 and the spray box 4 are both fixedly connected to the drive rod 201.
[0032] In practice, the exhaust gas containing carbon dioxide generated during the ship's operation is discharged into the treatment tank 103 through the air inlet pipe 1031. At this time, the drive motor 2 is started, and the treatment liquid is simultaneously input into the spray box 4 through the liquid inlet pipe 3. The drive motor 2 will drive the spray box 4 to rotate, and the rotation of the spray box 4 will drive the nozzle 4011 at its bottom to rotate, thereby enabling the treatment liquid to be sprayed evenly, so that the sprayed treatment liquid comes into uniform contact with the exhaust gas introduced below, thereby improving the treatment efficiency and effect of the exhaust gas.
[0033] When the drive rod 201 drives the spray box 4 to rotate, the drive rod 201 will also drive the conical filter box 5 fixedly connected to it to rotate simultaneously. At this time, under the centrifugal force of rotation, the impurities in the inclined hole 503 will be thrown out, thereby reducing the possibility of the inclined hole 503 being blocked during the processing. At the same time, through the inclined hole 503, the impurities blocked in the inclined hole 503 can be easily thrown out without affecting the filtered liquid.
[0034] Figure 3 , Figure 4 As shown, multiple sets of stirring rods 2011 are fixedly connected to the bottom side wall of the drive rod 201, and the multiple sets of stirring rods 2011 are evenly distributed on the drive rod 201.
[0035] When the drive rod 201 rotates, it will also drive the stirring rod 2011 fixedly connected to its bottom to rotate. The rotation of the stirring rod 2011 at the bottom will agitate the material at the bottom of the treatment tank 103, thereby preventing some sediment from settling to the bottom.
[0036] Figure 2 , Figure 3 As shown, a liquid extraction pipe 6 is fixedly connected to the inner wall of the processing tank 103. One end of the liquid extraction pipe 6 is connected to the processing tank 103, and the other end of the liquid extraction pipe 6 is connected to the extraction tank 102. When recovering the rich liquid containing carbon dioxide at the bottom of the processing tank 103, the rich liquid at the bottom of the processing tank 103 is extracted into the extraction tank 102 through the liquid extraction pipe 6 for carbon extraction.
[0037] Figure 4 , Figure 5 A sealing ring 502 is fixedly connected to the side wall of the conical filter box 5, and the sealing ring 502 abuts against the inner side wall of the treatment tank 103.
[0038] The sealing ring 502 provided on the side wall of the conical filter box 5 can ensure the connection and sealing between the conical filter box 5 and the inner side wall of the treatment tank 103, thereby ensuring the filtration effect of the conical filter box 5.
[0039] Figure 5 As shown, a baffle 501 is fixedly connected to the conical filter box 5.
[0040] Baffle 501 is an arc-shaped plate.
[0041] By connecting an arc-shaped baffle 501 to the conical filter box 5, when impurities in the inclined hole 503 are thrown out, the arc-shaped baffle 501 can block the collection of impurity materials, thereby preventing the materials from falling into the connection gap between the conical filter box 5 and the treatment tank 103, thus reducing the situation where materials fall into the gap and jam the conical filter box 5, and thus ensuring that the conical filter box 5 can rotate stably.
[0042] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
