Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide recovery, and in particular to a waste gas carbon dioxide recovery and separation device. Background Technology

[0002] Waste gas refers to the mixture of gases emitted into the atmosphere from human activities such as industrial production and transportation. It has a complex composition, containing pollutants such as carbon monoxide, nitrogen oxides, sulfur oxides, particulate matter, and carbon dioxide. If these waste gases are emitted directly without treatment, they will pollute the air, harm health, and exacerbate the greenhouse effect. Carbon dioxide, as a major greenhouse gas, contributes to global warming due to its excessive emissions. Currently, carbon capture technologies (such as chemical absorption and adsorption) can efficiently separate and recover carbon dioxide from waste gases. After compression and liquefaction, it can be used as a chemical raw material, in food processing, or for geological storage, achieving the dual goals of resource utilization and emission reduction.

[0003] However, in the existing technology, in order to prevent large particulate impurities in the exhaust gas from entering and affecting the separation effect, filter plates are usually installed at the pipe opening. But after a long period of operation, large particulate impurities will continue to accumulate and cover one side of the filter plate, which will lead to a deterioration in the filtration effect. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas carbon dioxide recovery and separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas carbon dioxide recovery and separation device, comprising a collection box, a vent pipe fixedly connected to the left side of the collection box, a purification box provided at the other end of the vent pipe, a filter plate provided inside the purification box, fixing blocks fixedly connected to both sides of the purification box, an electric push rod provided at the upper end of the fixing block, a top block fixedly connected to the upper end of the electric push rod, a fixing bolt provided inside the top block, a sliding rod provided at the lower edge of the top block, a cleaning pad fixedly connected to the lower end of the sliding rod, connecting blocks fixedly connected to the edges of both sides of the collection box, and a connecting rod provided inside the connecting block.

[0006] Preferably, an air outlet pipe is fixedly connected to the right side of the collection box, an installation groove is provided inside the collection box, an adsorption plate is provided inside the installation groove, a limit block is fixedly connected to the upper end of the adsorption plate, a limit groove is provided inside the limit block, and an arc plate is fixedly connected to the front and rear of the collection box.

[0007] Preferably, the arc-shaped plate has a threaded hole inside, and a guide hole is provided inside the arc-shaped plate near the threaded hole. A guide rod is slidably connected inside the guide hole. A short block is fixedly connected to one end of the guide rod. A connecting ring is fixedly connected to the upper end of the short block. A locking block is fixedly connected to one side of the connecting ring. A connecting ring is movably connected inside the connecting ring. A lead screw is fixedly connected to one side of the connecting ring.

[0008] Preferably, the connecting rod slides inside the connecting block via a top plate and an electric push rod.

[0009] Preferably, the number of the limiting blocks is two sets, and they are symmetrically arranged about the center line of the adsorption plate.

[0010] Preferably, the internal thread of the arc-shaped plate is adapted to the external thread of the lead screw.

[0011] Using the above technical solution, by activating the electric push rod, the top plate is moved upwards, and the sliding rod moves the cleaning pad accordingly, thereby cleaning large particles of impurities on one side of the filter plate. Under the continuous output of the electric push rod, the cleaning pad circulates up and down, thus completing the overall cleaning of the filter plate. The setting of two sets of connecting blocks and connecting rods can improve the stability during the process of driving the electric push rod to move the cleaning pad up and down. In addition, the staff can also separate the top block and the sliding rod through the fixing bolt, so that the cleaning pad can be removed from the inside of the purification box for maintenance. The filter plate can be cleaned by components such as the electric push rod, top block, connecting rod, sliding rod, and cleaning pad, thereby preventing it from being blocked by large particles of impurities and improving the filtration effect.

[0012] Using the above technical solution, by rotating the lead screw, under the action of the threaded hole inside the arc plate, the lead screw drives the connecting ring and connecting ring to move to one side, and the locking block slides out from the inside of the limiting block, releasing the limitation on the adsorption plate. At this time, simply pull the adsorption plate upward to achieve disassembly. Similarly, during installation, the adsorption plate is slid into the inside of the installation groove. When it reaches the preset position, the lead screw is rotated in the opposite direction, and the lead screw pushes the connecting ring and connecting ring to move in the opposite direction. The locking block re-enters the inside of the limiting block, thereby fixing and installing the adsorption plate. The adsorption plate can be quickly installed and removed through components such as the lead screw, connecting ring, connecting ring, and arc plate, so that it can be replaced after adsorption is completed, and the difficulty of replacement can also be reduced.

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1

[0022] Please see Figures 1-6 This utility model provides a technical solution: a waste gas carbon dioxide recovery and separation device, including a collection box 1, a vent pipe 2 fixedly connected to the left side of the collection box 1, a purification box 3 set at the other end of the vent pipe 2, a filter plate 12 set inside the purification box 3, a fixing block 4 fixedly connected to both sides of the purification box 3, an electric push rod 5 set at the upper end of the fixing block 4, a top block 6 fixedly connected to the upper end of the electric push rod 5, a fixing bolt 7 set inside the top block 6, a sliding rod 8 set at the lower edge of the top block 6, a cleaning pad 9 fixedly connected to the lower end of the sliding rod 8, connecting blocks 10 fixedly connected to both sides of the collection box 1, a connecting rod 11 set inside the connecting block 10, and the connecting rod 11 slides inside the connecting block 10 through the top plate in cooperation with the electric push rod 5.

[0023] Specifically, when the electric push rod 5 is activated, it pushes the top plate upward, and the slide rod 8 moves the cleaning pad 9 accordingly, thereby cleaning large particles of impurities on one side of the filter plate 12. With the continuous output of the electric push rod 5, the cleaning pad 9 rises and falls in cycles, thus completing the overall cleaning of the filter plate 12. The two sets of connecting blocks 10 and connecting rods 11 can improve the stability of the process of the electric push rod 5 moving the cleaning pad 9 up and down. In addition, the staff can also separate the top block 6 and the slide rod 8 through the fixing bolt 7, so that the cleaning pad 9 can be removed from the inside of the purification box 3 for maintenance. The filter plate 12 can be cleaned by components such as the electric push rod 5, the top block 6, the connecting rod 11, the slide rod 8, and the cleaning pad 9, thereby preventing it from being blocked by large particles of impurities and improving the filtration effect.

[0024] Example 2

[0025] Please see Figures 1-6 This utility model provides a technical solution: a waste gas carbon dioxide recovery and separation device, wherein an outlet pipe 13 is fixedly connected to the right side of the collection box 1, an installation groove 14 is provided inside the collection box 1, an adsorption plate 15 is provided inside the installation groove 14, a limiting block 16 is fixedly connected to the upper end of the adsorption plate 15, a limiting groove 17 is provided inside the limiting block 16, and an arc-shaped plate 18 is fixedly connected to the front and rear of the collection box 1, a threaded hole 19 is provided inside the arc-shaped plate 18, and a position of the arc-shaped plate 18 near the threaded hole 19 is provided. A guide hole 20 is provided, and a guide rod 21 is slidably connected inside the guide hole 20. A short block 22 is fixedly connected to one end of the guide rod 21, and a connecting ring 23 is fixedly connected to the upper end of the short block 22. A locking block 25 is fixedly connected to one side of the connecting ring 23. A connecting ring 24 is movably connected inside the connecting ring 23, and a lead screw 26 is fixedly connected to one side of the connecting ring 24. There are two sets of limiting blocks 16, and they are symmetrically arranged about the center line of the adsorption plate 15. The internal thread of the arc plate 18 is matched with the external thread of the lead screw 26.

[0026] Specifically, rotating the lead screw 26 causes the connecting ring 24 and connecting ring 23 to move to one side under the action of the threaded hole 19 inside the arc plate 18. The locking block 25 slides out from the inside of the limiting block 16, releasing the limiting of the adsorption plate 15. At this time, the adsorption plate 15 can be disassembled simply by pulling it upward. Similarly, during installation, the adsorption plate 15 is slid into the inside of the mounting groove 14. When it reaches the preset position, the lead screw 26 is rotated in the opposite direction. The lead screw 26 pushes the connecting ring 24 and connecting ring 23 to move in the opposite direction, and the locking block 25 re-enters the inside of the limiting block 16, thus fixing and installing the adsorption plate 15. The adsorption plate 15 can be quickly installed and removed through components such as the lead screw 26, connecting ring 24, connecting ring 23, and arc plate 18, so that it can be replaced after adsorption is completed, and the difficulty of replacement can also be reduced.

[0027] Working principle: When using this separation device, firstly, connect the pipe on one side of the purification box 3 to the fan used to discharge the exhaust gas. After the connection is complete, the exhaust gas is introduced into the purification box 3 under the action of the fan. After the exhaust gas enters the purification box 3, it will be filtered through the internal filter plate 12. During this process, large particles are intercepted by the filter plate 12. Then, the filtered exhaust gas enters the collection box 1 through the ventilation pipe 2. At this time, the carbon dioxide in the exhaust gas is absorbed by the adsorption plate 15 in the collection box 1, while the remaining gases in the exhaust gas are discharged through the exhaust pipe 13. After the adsorption plate 15 completes its adsorption operation, rotating the lead screw 26 causes the connecting ring 24 and connecting ring 23 to move to one side under the action of the threaded hole 19 inside the arc plate 18. The locking block 25 then slides out from inside the limiting block 16, releasing the limiting effect on the adsorption plate 15. At this point, simply pull the adsorption plate 15 upwards to disassemble it. Similarly, during installation, the adsorption plate 15 is slid into the mounting groove 14. When it reaches the preset position, rotating the lead screw 26 in the opposite direction causes the connecting ring 24 and connecting ring 23 to move in the opposite direction, and the locking block 25 re-enters the limiting block 16, thus fixing and installing the adsorption plate 15. The lead screw 26, connecting ring 24, connecting ring 23, and arc plate 18 enable quick loading and unloading of the adsorption plate 15, allowing for replacement after adsorption is complete. This also reduces the risk of damage. The filter plate 12 is easy to replace. When cleaning is required, the electric push rod 5 is activated, which pushes the top plate upward. The sliding rod 8 moves the cleaning pad 9 accordingly, thus cleaning large particles on one side of the filter plate 12. With the continuous output of the electric push rod 5, the cleaning pad 9 rises and falls in cycles, thus completing the overall cleaning of the filter plate 12. The two sets of connecting blocks 10 and connecting rods 11 can improve the stability of the cleaning pad 9 during the process of the electric push rod 5 moving upward and downward. In addition, the staff can also separate the top block 6 and the sliding rod 8 through the fixing bolt 7, so that the cleaning pad 9 can be removed from the inside of the purification box 3 for maintenance. The filter plate 12 can be cleaned by components such as the electric push rod 5, top block 6, connecting rod 11, sliding rod 8 and cleaning pad 9, thereby preventing it from being blocked by large particles and improving the filtration effect.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
