Description

Technical Field

[0001] The utility model relates to the technical field of flue gas carbon capture, in particular to a carbon dioxide collector. Background Art

[0002] A carbon dioxide collector is a device for capturing and separating carbon dioxide gas, which is commonly used in industrial production, environmental protection, scientific research and other fields. A carbon dioxide collector can be used to separate and recover carbon dioxide generated in the process, which can not only reduce greenhouse gas emissions, but also transport the carbon dioxide to other production processes that require carbon dioxide. After the carbon dioxide collector captures the carbon dioxide in the gas, the gas containing solid impurities will be directly discharged from the exhaust pipe. A Chinese patent with patent number CN 219559182U discloses a flue gas treatment carbon capture device, including a carbon capture device body, an exhaust pipe and a fixed ring, etc. The scheme drives the impeller to rotate through the airflow inside the exhaust pipe, so that the cleaning part rotates around the fixed ring as an axis to clean the impurities deposited in the exhaust pipe. The purpose is to prevent the accumulation of impurities from affecting the flue gas flow. However, when the scheme is actually used, it can only rotate and clean along the inner wall of the exhaust pipe in a circular shape. When facing solid impurities that are relatively firmly attached to the inner wall of the exhaust pipe, the cleaning efficiency is insufficient, and there are limitations in use.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4The utility model discloses a carbon dioxide collector, including a collector body 1, an exhaust pipe 2 is arranged at the gas outlet end of the collector body 1, an exhaust pipe 3 is arranged at the bottom of the exhaust pipe 2 and is interconnected, the exhaust pipe 3 is arranged on the side of the exhaust pipe 2 close to the collector body 1, a switch cover is arranged at the bottom of the exhaust pipe 3, a fan 4 is installed at the end of the exhaust pipe 2 away from the collector body 1, when in use, the switch cover is in a normally closed state, the collector body 1 is used to capture carbon dioxide in the gas, and other gases and solid impurities are discharged outwardly from the exhaust pipe 2, and the fan 4 is started to extract the gas in the exhaust pipe 2 outwardly to increase the efficiency of gas discharge.

[0022] In one embodiment, a filter screen 5 is installed in the exhaust pipe 2, and the impurity discharge pipe 3 is located between the inlet of the exhaust pipe 2 and the filter screen 5, and the spacing between the inlet of the exhaust pipe 2 and the filter screen 5 is the same as the diameter of the impurity discharge pipe 3. The moving end of the fan 4 is provided with a connecting shaft 6 that penetrates the filter screen 5. This design is to enable the solid impurities intercepted by the filter screen 5 to fall completely and directly and enter the impurity discharge pipe 3. The fan 4 is started to drive the connecting shaft 6 to rotate. A reciprocating motion device is provided at one end of the connecting shaft 6 that penetrates the filter screen 5. A scraping device that contacts the inner wall of the impurity discharge pipe 3 is provided on the reciprocating motion device. The rotation of the connecting shaft 6 drives the scraping device to rotate around the connecting shaft 6 as the center and scrape impurities on the inner wall between the inlet of the exhaust pipe 2 and the filter screen 5. The reciprocating motion device is used to drive the scraping device to reciprocate along the exhaust direction of the exhaust pipe 2 when the connecting shaft 6 rotates.

[0023] In a specific implementation, when the collector body 1 captures carbon dioxide in the gas and continuously discharges other gases, the solid impurities in the gas are intercepted by the filter 5. At this time, the solid impurities are only between the inlet of the exhaust pipe 2 and the filter 5. The continuous operation of the fan 4 will drive the connecting shaft 6 to rotate, and the reciprocating motion device and the scraping device will also rotate synchronously with the rotation of the connecting shaft 6. In this process, the scraping device will rotate with the connecting shaft 6 as the center and scrape the impurities on the inner wall of the exhaust pipe 2 from the inlet to the filter 5, and the reciprocating motion device will drive the scraping device to reciprocate along the exhaust direction of the exhaust pipe 2 when the connecting shaft 6 rotates, thereby further pushing the impurities on the inner wall of the exhaust pipe 2 laterally. This design can further effectively scrape off the impurities on the inner wall of the exhaust pipe 2, and the scraped impurities will fall directly and enter the impurity exhaust pipe 3. The staff only needs to open the switch cover at regular intervals to concentrate the impurities for processing, so as to achieve efficient scraping of impurities on the exhaust pipe of the carbon dioxide collector.

[0024] It can be understood that when the reciprocating device drives the scraping device to reciprocate along the exhaust direction of the exhaust pipe 2, the reciprocating motion of the scraping device will not collide with the filter 5. This design is to prevent the scraping device from affecting the installation stability of the filter 5 when it is working. In addition, the device can effectively separate the solid impurities in the gas separately, and no additional solid impurity separation equipment is required to separate the solid impurities, thereby reducing the production cost.

[0025] In one embodiment, the reciprocating motion device includes a sleeve body 7 slidably mounted on the connecting shaft 6, a first bevel gear ring 9 arranged at the center of the filter screen 5, and a second bevel gear ring 10 arranged on the side of the sleeve body 7 close to the first bevel gear ring 9. The sleeve body 7 and the first bevel gear ring 9 are both located on the side of the filter screen 5 close to the entrance of the exhaust pipe 2. The first bevel gear ring 9 and the second bevel gear ring 10 are both annular, and their ends close to each other are provided with a plurality of bevel teeth distributed in an annular shape and engaged with each other, while the connecting shaft 6 passes through the first bevel gear ring 9, and a tension spring is provided at one end of the connecting shaft 6 close to the sleeve body 7, and the other end of the tension spring is connected to the inner wall of the sleeve body 7.

[0026] In specific implementation, when the connecting shaft 6 rotates, the sleeve 7 and the second bevel gear ring 10 will rotate synchronously therewith. At this time, the rotating second bevel gear ring 10 will contact the bevel teeth on the first bevel gear ring 9 and move toward the side away from the first bevel gear ring 9 along the shape of the bevel teeth. At this time, the tension spring will expand. When it moves to the tooth gap of the bevel teeth of the first bevel gear ring 9, the tension spring will pull the sleeve 7 toward the side close to the first bevel gear ring 9. The continuous rotation of the connecting shaft 6 will cause the above-mentioned sleeve 7 to slide back and forth in a straight line during rotation, thereby driving the scraping device to synchronously reciprocate in a straight line on the inner wall of the exhaust pipe 2 during rotation and scrape off impurities attached to the inner wall of the exhaust pipe 2.

[0027] In one embodiment, the scraping device includes a connecting rod 15 connected to the sleeve 7 at one end, and a scraping plate 8 is provided at the other end of the connecting rod 15, and the side of the scraping plate 8 away from the connecting rod 15 contacts the inner wall of the exhaust pipe 2, and the scraping plate 8 is provided with an anti-scratch layer, which can be a silicone layer, for preventing the scraping plate 8 from scratching the inner wall of the exhaust pipe 2.

[0028] In one embodiment, a cleaning device is provided on the scraping device, and the cleaning device is used to clean the side of the filter screen 5 close to the inlet of the exhaust pipe 2 when the reciprocating device and the scraping device rotate.

[0029] In one embodiment, the cleaning device includes a first bevel gear 11 which is arranged on the first bevel gear ring 9 and the centers of which coincide with each other, a second bevel gear 13 which is rotatably arranged on the first bevel gear ring 9 through a connecting shaft and meshes with the first bevel gear 11 at a right angle, a reciprocating screw 12 which is arranged on the other side of the second bevel gear 13 away from the first bevel gear ring 9, and a cleaning frame 14 which is arranged on the reciprocating screw 12 and cooperates with the reciprocating screw 12. A bearing which is not shown in the figure is sleeved on the first bevel gear ring 9, and the outer ring of the bearing is connected to the second bevel gear 13 through a connecting shaft, and the second bevel gear 1 3 is rotatably connected to the connecting shaft, a guide groove in the shape of a strip and arranged along the length direction of the scraper plate 8 is provided in the scraper plate 8, the other end of the reciprocating screw 12 away from the second bevel gear 13 is inserted into the guide groove, a limiting groove 16 in the shape of a strip and arranged along the length direction of the reciprocating screw 12 is provided on the connecting rod 15, the cleaning portion of the cleaning frame 14 contacts the filter screen 5, and one end of the cleaning frame 14 away from the cleaning portion is inserted into the limiting groove 16, and the second bevel gear 13 is used to cooperate with the first bevel gear 11 to drive the reciprocating screw 12 to rotate when the reciprocating screw 12 rotates around the first bevel gear ring 9 as the center.

[0030] In the specific implementation, when the connecting shaft 6 rotates and drives the sleeve 7 to rotate, the scraper plate 8 will also rotate synchronously, thereby driving the reciprocating screw 12 to rotate synchronously with the first bevel gear ring 9 as the center. In this process, the second bevel gear 13 meshing with the first bevel gear 11 will also rotate synchronously with the first bevel gear ring 9 as the center. The second bevel gear 13 is meshed with the first bevel gear 11 and rotates around the first bevel gear 11 in a ring shape, so that the second bevel gear 13 itself will rotate by itself, and the second bevel gear 13 synchronously drives the reciprocating screw 12 to rotate, and makes the cleaning frame 14 on the reciprocating screw 12 reciprocate along the length direction of the reciprocating screw 12. At this time, the cleaning frame 14 can rotate around the connecting shaft 6 as the center, and can also reciprocate along the length direction of the reciprocating screw 12, so that the impurities on the filter screen 5 can be cleaned very comprehensively.

[0031] It should be noted that when the cleaning frame 14 reciprocates along the length direction of the reciprocating screw 12, one end of it is inserted into the limit groove 16, thereby ensuring that the movement and adjustment of the cleaning frame 14 is very stable, and when the reciprocating motion device drives the scraping device to reciprocate, one end of the reciprocating screw 12 is always in the guide groove, so that when the scraping plate 8 rotates around the sleeve 7 as the center, it can drive the reciprocating screw 12 to rotate synchronously, and the scraping plate 8 will not affect the normal use of the reciprocating screw 12 when it reciprocates in a straight line.

[0032] It can be understood that the cleaning frame 14 has a compact overall structure, and can clean the filter screen 5 over a large area without affecting the normal flow of gas in the exhaust pipe 2, thereby facilitating practical use.

[0033] In one embodiment, a sealing sleeve (not shown) is provided at the center of the filter 5, and the connecting shaft 6 can rotatably penetrate the sealing sleeve, and the connecting shaft 6 and the sealing sleeve are dynamically sealed to prevent impurities from flying out of the exhaust pipe 2 from the installation point of the filter 5 and the connecting shaft 6.
