Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide recovery, in particular to a device for recovering carbon dioxide from coal-fired flue gas. Background Art

[0002] Treat the waste gas from the pollution source to remove harmful substances and make it meet the recycling requirements. Waste gas treatment is the process of treating the waste gas from the pollution source to remove harmful substances. Carbon dioxide is separated from the waste gas by adsorption or dissolution. Carbon dioxide collection is the process of separating carbon dioxide from the waste gas by adsorption or dissolution. There are two common collection methods: adsorption and dissolution. Adsorption is to separate carbon dioxide from the waste gas by the adsorption capacity of certain adsorbents. Dissolution is to dissolve carbon dioxide in a solvent and then separate carbon dioxide from the solvent by distillation or other methods. When using chemical agents to react with waste gas, it is necessary to filter the impurities in the waste through a bag filter. The impurities blocked outside the filter bag will accumulate in the dust storage box in the dust collector. When transferring the impurities in it, the receiving bucket is often placed at the outlet of the dust storage box to receive the impurities and dust. However, this method causes a large amount of impurities to float in the air again, causing environmental pollution and affecting the health of the staff. Utility Model Content

[0025] Specifically, the utility model prevents impurities in the dust storage cart 3 from floating out by providing a cover plate 61. When the dust storage cart 3 is pulled so that the feed port of the dust storage cart 3 is away from the discharge port of the dust storage box 2, the cover plate 61 rotates to seal the feed port of the dust storage cart 3, so that the dust impurities in the dust storage cart 3 will not be blown up and pollute the environment. The discharge port of the dust storage box 2 still slides on the dust storage cart 3 until it is connected with the feed port of another dust storage cart 3. In this process, the dust impurities that have not been discharged cleanly in the dust storage box 2 will not leak out, thereby achieving dust-free dust discharge, protecting the ecological environment, and providing protection for the health of the staff.

[0026] In another embodiment of the present invention, reference Figures 1 to 5, a device for recovering carbon dioxide in coal-fired flue gas comprises: a dust collector body 1, a dust storage box 2 is fixedly installed below the dust collector body 1, a dust storage car 3 is arranged below the dust storage box 2, and the two sides of the dust storage car 3 are respectively fixedly connected with a first hook 9 and a second hook 10, when the second hook 10 on one dust storage car 3 is inserted into the first hook 9 on the other dust storage car 3, the connection of the two dust storage cars 3 is completed, and when they need to be disassembled, only one of the dust storage cars 3 needs to be slid relative to the other dust storage car 3 to make the first hook 9 slide out of the second hook 10, so that the two dust storage cars 3 are separated, and four universal wheels 32 are arranged below the dust storage car 3, and the universal wheels 32 are universal brake wheels with a self-locking function. The dust storage car 3 is placed below the dust storage box 2 to collect dust and impurities When the dust storage cart 3 is in a state of being compacted, the universal wheel 32 is locked to prevent the dust storage cart 3 from moving. The bottom end of the dust storage cart 3 is fixedly connected to the telescopic pull rod 33, and the telescopic pull rod 33 includes a fixed rod 331, which is fixedly connected to the dust storage cart 3. A movable rod 332 is slidably arranged in the fixed rod 331, and a slide groove 3311 is provided in the fixed rod 331. The movable rod 332 is slidably arranged in the slide groove 3311, and a block is installed at the exit of the slide groove 3311 to prevent the movable rod 332 from sliding out. The discharge port of the dust storage box 2 abuts on the dust storage cart 3, and the top of the dust storage cart 3 is a guide rail 31, and the feed port of the dust storage box 2 abuts on the guide rail 31. When the two dust storage carts 3 are connected together by the first hook 9 and the second hook 10, the ends of the two guide rails 31 are tightly attached to each other. Figure 2 When the dust storage cart 3 on the left is pulled, the discharge port of the dust storage box 2 slides on the guide rail 31 relative to the dust storage cart 3, and a rotating shaft 6 is rotatably arranged in the dust storage cart 3, and a cover plate 61 is fixedly connected to the rotating shaft 6. When the feed port of the dust storage cart 3 leaves the discharge port of the dust storage box 2, the cover plate 61 blocks the feed port of the dust storage cart 3, and a gear 7 is fixedly sleeved on the rotating shaft 6. A wedge block 5 is slidably arranged in the dust storage cart 3, and the wedge block 5 is connected to the dust storage cart 3 through a second spring 51. One end of the second spring 51 is fixedly connected to the wedge block 5, and the other end of the second spring 51 is fixedly connected to the guide rail 31. The top end of the wedge block 5 The two sides are provided with inclined surfaces so that when the wedge block 5 is subjected to lateral force, its component force can overcome the elastic force of the second spring 51, thereby causing the wedge block 5 to move downward. A tooth groove 52 is provided on the wedge block 5, and the tooth groove 52 is meshed with the gear 7. A material guide nozzle 4 is slidably provided at the lower end of the dust storage box 2, and the material guide nozzle 4 is connected to the dust storage box 2 through a first spring 41. One end of the first spring 41 is fixedly connected to the material guide nozzle 4, and the other end of the first spring 41 is fixedly connected to the dust storage box 2. A plunger 42 is fixedly connected inside the material guide nozzle 4, and holes are provided around the plunger 42 for connecting the dust storage box 2 with the dust storage vehicle 3.

[0027] In this utility model, reference is made to Figures 1 to 5When dust discharge is required, first pull the movable rod 332 out of the slide slot 3311, pull the movable rod 332 to drive the dust storage cart 3 to move forward, so that both dust storage carts 3 slide, and the guide nozzle 4 overcomes the elastic force of the first spring 41 under the action of the pulling force, so that the guide nozzle 4 retracts into the dust storage box 2, and the plunger 42 blocks the discharge port of the dust storage box 2, thereby preventing dust in the dust storage box 2 from leaking out. At this time, the dust storage box 2 is no longer in contact with the wedge block 5, and the wedge block 5 moves upward under the elastic force of the second spring 51, driving the gear 7 meshing with the tooth groove 52 to rotate, so that the cover plate 61 rotates to block the feed port of the dust storage cart 3, and then Continue to pull the movable rod 332, so that the dust storage box 2 squeezes the wedge block 5 in the other dust storage cart 3, so that the wedge block 5 moves downward and drives the gear 7 to rotate, so that the cover plate 61 rotates and opens the feed port of the dust storage cart 3. At this time, the guide nozzle 4 slides downward under the elastic force of the first spring 41, and the plunger 42 no longer blocks the discharge port of the dust storage box 2, so that the dust and impurities in the dust storage box 2 are discharged into the dust storage cart 3. Finally, the full dust storage cart 3 is removed and pulled away, and after the dust and impurities in the dust storage cart 3 filled with dust and impurities are processed, the empty dust storage cart 3 is continued to be installed behind the dust storage cart 3 that is being loaded, waiting for the next replacement.
