[0002] Carbon dioxide is widely present in the atmosphere, water and rock formations; it is produced in the processing of coal, oil and carbonates, as well as in the combustion of fuels. In industry, industrial production and industrial power generation will produce a large amount of carbon dioxide waste gas, as well as some other products such as nitrogen. Regardless of the source of carbon dioxide gas, it must be separated and purified before it can be used. Therefore, a carbon dioxide waste gas purification adsorption tower is used to refine carbon dioxide.

[0003] Prior art includes a utility model with publication number CN216778401U, which discloses an adsorption tower for purifying carbon dioxide waste gas. The patent adopts an adsorption tank for separating carbon dioxide, a pressure control pump for changing the pressure change inside the adsorption tank, an adsorption device capable of fully adsorbing carbon dioxide is movably installed in the middle of the adsorption tank, and a movable limiting mechanism is symmetrically arranged on the outer wall of the adsorption device so that the adsorption device can move within a certain range inside the adsorption tank. The adsorption device is composed of a plurality of closely connected adsorption beds, and one end of each adsorption bed is fixedly connected with a vibration generating mechanism for causing the adsorption device to vibrate when working. The utility model solves the problems that thinner carbon molecular sieves are easily damaged, the content of carbon dioxide desorbed by a single pressure swing adsorption is low, and the thicker carbon molecular sieve layer cannot be fully adsorbed. Even if a curved structure is adopted, there is still a lot of carbon dioxide in the adsorbed waste gas, making it difficult to fully adsorb.

[0004] The applicant has found in daily work that in the process of gas filtering, there is a problem that the connecting frame and the filter frame are prone to shaking, making filtering difficult. Utility Model Content

[0005] The utility model aims to solve the shortcoming in the prior art that the connection frame is difficult to replace quickly, and proposes an adsorption tower for purifying carbon dioxide waste gas.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adsorption tower for purifying carbon dioxide waste gas, comprising a tower body and a connecting device, the lower surface of the tower body is fixedly connected to a base, the upper surface of the tower body is provided with an air outlet pipe, the side of the tower body is provided with an air inlet pipe, the side of the tower body is provided with a controller, the connecting device is arranged on the surface of the tower body, the connecting device comprises a connecting frame and a pull handle, the connecting frame is slidably connected to the inner wall of the tower body, the pull handle is fixedly connected to the surface of the connecting frame, and the two sides of the connecting frame are fixedly connected with a first connecting block, by arranging the first connecting blocks on both sides of the connecting frame, the connection frame can be stabilized and kept balanced, thereby reducing the situation where the connection frame is prone to deviation when the equipment is in use, and the side of the tower body is provided with a second connecting block, and the inner wall of the first connecting block is slidably connected with a resist rod, and the resist rod is arranged to facilitate the movement of the card rod.

[0007] Furthermore, both ends of the abutment rod are fixedly connected with clamping rods, and the clamping rods are clamped with the inside of the second connection block. The clamping rods are provided to facilitate connection restriction of the first connection block and the second connection block.

[0008] Furthermore, a replacement device is provided inside the connecting frame, and the replacement device includes a filter block and a filter frame. The filter frame is provided on the inner wall of the connecting frame, and the filter block is fixedly connected to the inner wall of the filter frame. A slot is provided on the inner wall of the connecting frame, and a rotating block is rotatably connected to the inner wall of the rotating block. A pull rod is slidably connected to the inner wall of the rotating block. By providing the pull rod, the filter frame can be firmly connected to the inside of the connecting frame, thereby reducing the situation in which the filter frame rises and falls inside the connecting frame when the equipment is in use, making it difficult to effectively filter.

[0009] Furthermore, the pull rod is engaged with the inner wall of the slot, and a retaining ring is fixedly connected to the surface of the pull rod, and the retaining ring is provided to facilitate limiting the spring.

[0010] Furthermore, a spring is fixedly connected to the surface of the butt ring, and one end of the spring away from the butt ring is fixedly connected to one end of the rotating block. The spring is provided to facilitate applying elastic force to the pull rod.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, when the device absorbs the impurities inside the gas, the gas is passed into the interior of the tower body through the air inlet pipe, and then the gas is filtered inside the tower body, and the impurities in the gas are adsorbed in the filter block, and then the filtered gas is discharged through the air outlet pipe. When using the device, the user manually lifts the push rod, and the movement of the push rod drives the clamping rod to move, and the clamping rod moves away from the interior of the second connecting block, and then the connecting block loses its restraint, and the pull handle is pulled to drive the connecting frame to move away from the interior of the tower body. By setting a connecting device, the connecting block and the tower body are effectively connected, which plays a role in stabilizing the connecting frame, reducing the use of bolts to stabilize the surface of the connecting frame and the tower body when the device is in use. The installation and removal of the bolts require the use of tools for operation. The use of tools is too cumbersome, resulting in low work efficiency for the user, and improving the stability of the device.

[0013] 2. In the utility model, by setting a replacement device, when using the equipment, the user pulls the pull rod, and when the pull rod moves, it drives the spring to displace and deform to generate elastic force, and then the pull rod moves out of the slot, and then the pull rod fits into the inside of the rotating block, and then the rotating block loses its restraint. When the pull rod is pulled to rotate, the rotating block is driven to rotate perpendicular to the filter frame, and the pull rod is lifted to drive the filter frame to move, and the filter block is replaced. By setting the replacement device, the filter block is effectively restricted, which plays a role in replacing the filter block, reduces the long-term use of the filter frame when the equipment is in use, and is prone to blockage, making it difficult to filter the gas, thereby improving the practicability of the equipment.

[0021] The specific settings and functions of the connecting device 6 and the replacing device 7 are described in detail below.

[0022] In this embodiment: the connection device 6 is arranged on the surface of the tower body 1 , and the connection device 6 includes a connection frame 61 and a pull handle 62 . The connection frame 61 is slidably connected to the inner wall of the tower body 1 , and the pull handle 62 is fixedly connected to the surface of the connection frame 61 .

[0023] Specifically, first connecting blocks 63 are fixedly connected to both sides of the connecting frame 61 .

[0024] In this embodiment, by providing the first connection blocks 63 on both sides of the connection frame 61, the connection frame 61 can be stabilized and kept balanced, thereby reducing the possibility of deviation of the connection frame 61 when the device is in use.

[0025] Specifically, a second connection block 64 is provided on the side of the tower body 1 , and a stopper 65 is slidably connected to the inner wall of the first connection block 63 . The stopper 65 is provided to facilitate the movement of the clamping rod 66 .

[0026] Specifically, both ends of the abutment rod 65 are fixedly connected with clamping rods 66 , which are clamped with the inside of the second connection block 64 . The clamping rods 66 are provided to facilitate connection restriction between the first connection block 63 and the second connection block 64 .

[0027] In this embodiment: a replacement device 7 is arranged inside the connecting frame 61, and the replacement device 7 includes a filter block 71 and a filter frame 72. The filter frame 72 is arranged on the inner wall of the connecting frame 61, and the filter block 71 is fixedly connected to the inner wall of the filter frame 72. A card slot 73 is opened on the inner wall of the connecting frame 61, and a rotating block 74 is rotatably connected to the inner wall of the filter frame 72. A pull rod 75 is slidably connected to the inner wall of the rotating block 74.

[0028] In this embodiment, by providing a pull rod 75, the filter frame 72 can be firmly connected to the inside of the connection frame 61, thereby reducing the situation where the filter frame 72 rises and falls inside the connection frame 61 when the device is in use, making it difficult to filter effectively.

[0029] Specifically, the pull rod 75 is engaged with the inner wall of the slot 73 , and a retaining ring 76 is fixedly connected to the surface of the pull rod 75 . The retaining ring 76 is provided to facilitate limiting the spring 77 .

[0030] Specifically, a spring 77 is fixedly connected to the surface of the butt ring 76 , and one end of the spring 77 away from the butt ring 76 is fixedly connected to one end of the rotating block 74 . The spring 77 is provided to facilitate applying elastic force to the pull rod 75 .

[0031] Working principle: when the device absorbs the impurities inside the gas, the gas is passed into the tower body 1 through the air inlet pipe 4, and then the gas is filtered inside the tower body 1, and the impurities in the gas are adsorbed in the filter block 71, and then the filtered gas is discharged through the air outlet pipe 3. When using the device, the user manually lifts the push rod 65, and when the push rod 65 moves, it drives the clamping rod 66 to move, and the clamping rod 66 moves out of the second connecting block 64, and then the connecting block loses its restraint, and the pull handle 62 is pulled to drive the connecting frame 61 to move out of the tower body 1. By setting the connecting device 6, the connecting block and the tower body 1 are effectively connected, which plays a role in stabilizing the connecting frame 61, reducing the use of bolts to stabilize the surface of the tower body 1. The installation and removal of the bolts require the use of tools. The use of tools is too cumbersome, resulting in low work efficiency for the user, thereby improving the stability of the equipment.

[0032] When using the device, the user pulls the pull rod 75. When the pull rod 75 moves, it drives the spring 77 to displace and deform to generate elastic force, and then the pull rod 75 moves out of the slot 73, and then the pull rod 75 is adapted to the inside of the rotating block 74, and then the rotating block 74 is freed from the restraint. When the pull rod 75 is pulled to rotate, the rotating block 74 is driven to rotate perpendicular to the filter frame 72. The pull rod 75 is lifted to drive the filter frame 72 to move and replace the filter block 71. By setting the replacement device 7, the filter block 71 is effectively restricted, which plays a role in replacing the filter block 71, reduces the long-term use of the filter frame 72 when the device is in use, and is prone to blockage, making it difficult to filter the gas, thereby improving the practicability of the device.
