A vertical multi-layer carbon dioxide capture device includes a processing box, an air inlet and an air outlet. The multi-layer adsorption structure provided in the carbon dioxide capture device remains in a vertical state, so that the carbon dioxide will undergo multi-stage purification and filtration when flowing inside the processing box, and the adsorption material is easy to replace later. The adjustment component can adjust the angle and height of the air inlet of the processing box, and can be adapted to a variety of carbon dioxide emission equipment. It can accurately capture carbon dioxide and is not easy to leak. The switching component allows the carbon dioxide capture device to switch between mobile and fixed states, increasing the flexibility of the device. It can ensure a certain effect of carbon dioxide capture requirements, and meet the emission reduction goals of small and medium-sized enterprises to spend little money to achieve great things.

[0012] According to the above technical scheme, it also includes an anti-caking device, which includes a cam, a moving rod, a pressure plate and a screen plate. The rotation of the receiving shaft drives the cam to rotate, and the rotation of the cam contacts and squeezes the moving rod to move upward. The cam is fixedly installed on the circumferential surface of the receiving shaft, and the moving rod slides through the upper and lower walls of the lifting plate. The pressure plate is fixedly installed above the moving rod, and the screen plate is fixedly installed on the inner wall of the discharge frame.

At the same time, when the discharge roller stops working, the pressure plate and the screen plate are attached to each other under the action of the telescopic elastic rod 2 to achieve isolation of the discharge frame, thereby maintaining the stability of the internal environment of the storage box.

[0014] The present invention provides a multi-layer carbon dioxide capture device. It has the following beneficial effects:

[0015] (1) This multi-layer carbon dioxide capture device can flip and stir the powdered steel slag and catalyst in the filter frame and filter plate through the sleeve and spiral scraper, thereby increasing the contact area between the carbon dioxide in the exhaust gas and the steel slag and catalyst, thereby improving the carbon fixation effect of carbon dioxide. At the same time, the steel slag and catalyst gradually enter the interior of the slag storage frame during the rotation process, thereby avoiding the gradual reduction of the carbon fixation effect of the steel slag and catalyst due to long-term treatment of the exhaust gas. In addition, the mass of the steel slag gradually increases during the carbon fixation process, thereby causing the filter plate to move downward under the action of gravity, and the slag discharge hole and the slag discharge pipe are connected under the action of the connecting plate and the baffle, so that the steel slag after carbon capture is discharged to the outside, realizing the automation of slag discharge, effectively improving the carbon capture effect and reducing subsequent maintenance costs.

[0016] (2) In this multi-layer carbon dioxide capture device, the rotation of the casing drives the discharge tray to rotate, and the steel slag and catalyst inside the discharge frame are spread on the top of the discharge tray under the action of the discharge roller. At the same time, the discharge tray rotates to evenly sprinkle the steel slag and catalyst on its surface inside the filter frame through the oblique surface, thereby achieving stable and uniform discharge of the steel slag and catalyst. At the same time, under the action of the telescopic elastic rod, the discharge roller can always fit with the discharge tray, maintain stability during the discharge process, and reduce subsequent maintenance costs.

[0017] (3) In this multi-layer carbon dioxide capture device, the discharge roller rotates to drive the pressure plate to move upward through the cam and the moving rod, and the pressure plate moves up and down under the action of the telescopic elastic rod 2. The up and down movement of the pressure plate can effectively crush some agglomerated slag and catalyst under the action of the screen plate, thereby preventing the water vapor in the exhaust gas from entering the interior of the storage box through the discharge frame during the long-term treatment of the exhaust gas, causing some slag and catalyst to agglomerate in a humid environment and become blocked inside the discharge frame. At the same time, when the equipment stops working, the pressure plate and the screen plate fit together to block the discharge frame, thereby separating the equipment frame from the storage box and maintaining the stability of the internal environment of the storage box.

The filter frame 8 stores steel slag and catalyst inside. The connecting plate 15 moves downward to drive the baffle 14 to move downward. The baffle 14 moves downward so that the slag discharge hole 141 on its surface is connected with the slag discharge pipe 6, and the steel slag after carbon capture in the slag storage frame 13 is discharged to the outside through the slag discharge pipe 6; wherein, a discharge device for discharging steel slag and catalyst is provided on the surface of the equipment frame 1, and the discharge device includes a storage box 171 and a discharge tray 172, the storage box 171 is fixedly penetrated through the upper inner and outer walls of the equipment frame 1, and the discharge tray 172 is fixedly mounted on the circumferential surface of the sleeve 10.

[0029] One end of the connecting plate 15 away from the slag storage frame 13 is fixedly connected to the filter plate 9, and the other end of the connecting plate 15 away from the filter plate 9 is fixedly connected to the baffle 14.

[0034] A discharge groove 177 is provided on the surface of the discharge roller 176, and the discharge roller 176 contacts the discharge tray 172. The surface of the discharge tray 172 is set as a bevel surface.

[0035] It also includes an anti-caking device, which includes a cam 181, a moving rod 182, a pressure plate 183 and a screen plate 184. The rotation of the receiving shaft 175 drives the cam 181 to rotate, and the cam 181 rotates to contact and squeeze the moving rod 182 to move upward. The cam 181 is fixedly installed on the circumferential surface of the receiving shaft 175, and the moving rod 182 slides through the upper and lower walls of the lifting plate 173.

At the same time, when the discharge roller 176 stops working, the pressure plate 183 and the screen plate 184 are attached to each other under the action of the telescopic elastic rod 186 to achieve the blocking of the discharge frame 174.

[0037] When the present embodiment is working, the sleeve 10 rotates to drive the discharge tray 172 to rotate, the discharge tray 172 rotates to contact and drive the discharge roller 176 to rotate, the discharge roller 176 rotates to spread the steel slag and catalyst inside the discharge frame 174 above the discharge tray 172 through the discharge groove 177 on its surface, and at the same time, the discharge tray 172 rotates to evenly sprinkle the steel slag and catalyst on its surface inside the filter frame 8 through the beveled surface, thereby achieving stable and uniform discharge of the steel slag and catalyst, increasing the contact area between the steel slag and catalyst and the exhaust gas, and thus improving the carbon fixation effect of the steel slag and catalyst, while avoiding the accumulation of too much steel slag and catalyst at the same position, thereby causing the filter plate 9 to get stuck during the up and down movement. It also affects the stability of the carbon fixation device during operation. At the same time, when the filter plate 9 moves up and down, it will drive the sleeve 10 to move up and down. When the sleeve 10 moves upward, it drives the discharge tray 172 to move upward. The discharge tray 172 moves upward to contact and drive the discharge roller 176 to move upward. The discharge roller 176 moves upward to drive the receiving shaft 175 to move upward. The receiving shaft 175 moves upward to drive the discharge frame 174 to move upward.

[0038] During the discharge process, the discharge roller 176 rotates and drives the receiving shaft 175 to rotate. The receiving shaft 175 rotates and drives the cam 181 to rotate.

The moving rod 182 moves downward and drives the pressure plate 183 to move downward. The pressure plate 183 moves up and down, and under the action of the screen plate 184, part of the agglomerated slag and catalyst can be effectively crushed. The crushed slag and catalyst pass through the screen on the surface of the screen plate 184. Hole 187 enters the interior of the discharge frame 174 and is discharged into the interior of the filter frame 8 under the action of the discharge roller 176, which can effectively prevent the exhaust gas from entering the interior of the storage box 171 through the discharge frame 174 during the long-term treatment of the exhaust gas, causing part of the slag and the catalyst to react inside the discharge frame 174, thereby affecting the subsequent carbon fixation effect and reducing the maintenance cost of the equipment. At the same time, when the exhaust gas treatment work is stopped, the discharge roller 176 stops working under the action of the telescopic elastic rod 186, so that the pressure plate 183 and the screen plate 184 are attached to the discharge frame 174 and the discharge frame 174 is blocked, thereby realizing the separation of the equipment frame 1 and the storage box 171, maintaining the stability of the internal environment of the storage box 171, and preventing the slag and the catalyst from affecting its effect under the action of the exhaust gas, thereby further reducing the subsequent maintenance cost.
