[0002] In the process of recycling used lithium batteries, the electrolyte waste gas is effectively dedusted by cyclone dust removal and dry filtration to remove micron-level dust. After dry filtration, it is defluorinated with alkaline solution and then enters the three-chamber RTO thermal storage pyrolysis. After molecular sieve adsorption, low-standard waste gas emissions are guaranteed.
[0003] When performing dry filtration, the existing dry filter is mainly composed of a main body, a frame, an air inlet, an air outlet, a fixing block, a primary filter element, a sealing strip, a secondary filter element, and a tertiary filter element. In order to expand the filtration area and ensure the filtration effect, a baffle filter element is generally used, and the gas passes through the baffle filter elements of each level in sequence in the horizontal direction, thereby performing dry filtration on the electrolyte waste gas.
[0004] During actual use, it was found that although the baffle filter element can expand the filtration area, the dust in the electrolyte exhaust gas adheres to the surface of the baffle filter element. When the baffle filter element is taken out for cleaning, the dust attached to its surface easily falls into the equipment, which is not conducive to the subsequent dry filtration of the electrolyte exhaust gas. Utility Model Content
[0005] The utility model aims to provide an electrolyte waste gas dry filtering device which can ensure the filtering area and is not easy to drop dust in view of the above-mentioned deficiencies in the prior art.

[0008] A lifting rod is fixedly connected to the inner bottom of the tertiary filter cartridge, and the lifting rod moves vertically through the secondary filter cartridge and the primary filter cartridge. A sealing ring located on the top of the sealing partition is detachably sleeved on the proximal end of the upper end of the lifting rod, and the upper ends of the primary filter cartridge, the secondary filter cartridge and the tertiary filter cartridge are all in contact with the sealing ring.
[0009] The bottoms of the primary filter cartridge and the secondary filter cartridge in the above-mentioned electrolyte waste gas dry filtration equipment are fixedly connected with a connecting sleeve that is movably mounted on the lifting rod, a supporting ring is fixedly connected to the lower end of each connecting sleeve, and a first sealing ring that fits the lifting rod is fixedly connected to the inner ring of each connecting sleeve.

Since the filter mechanism is cylindrical, it can ensure a large filtration area, thereby ensuring the filtration effect; and during the filtration process, the dust in the electrolyte waste gas remains in the cylindrical filter mechanism.

DETAILED DESCRIPTION
[0020] See also Figures 1 to 3 As shown, a dry-type filtration device for electrolyte waste gas of the utility model comprises a filter tank 1 arranged in the horizontal direction, so that the electrolyte waste gas can flow in the horizontal direction for dry filtration. An air inlet 2 is provided at one end of the filter tank 1, and an air outlet 3 is provided at the other end of the filter tank 1. The electrolyte waste gas enters the filter tank 1 from the air inlet 2 and is discharged from the air outlet 3. A guide plate 4 close to the air inlet 2 is fixedly connected in the filter tank 1, and the guide plate 4 is tilted toward the air outlet 3, so as to guide the electrolyte waste gas. A sealing partition 5 arranged in the horizontal direction is fixedly connected to the upper end of the guide plate 4, and a plurality of cylindrical filter mechanisms 6 arranged in the vertical direction are arranged on the sealing partition 5. The sealing partition 5 cooperates with the guide plate 4 to separate the internal space of the filter tank 1, so that the electrolyte waste gas can pass through the cylindrical filter mechanism 6 in the vertical direction and then be discharged. The top of the filter tank 1 is provided with an inspection port 7 corresponding to each cylindrical filter mechanism 6, so that the cylindrical filter mechanism 6 can be inspected or cleaned. When in use, through the cooperation of the guide plate 4 and the sealing partition 5, the electrolyte waste gas enters the filter tank 1 in the horizontal direction through the air inlet 2, and can flow to the top of the filter tank 1 under the action of the guide plate 4 and the sealing partition 5, and then enter the cylindrical filter mechanism 6 from top to bottom, and finally be discharged in the horizontal direction through the air outlet 3. The dust in the electrolyte waste gas remains in the cylindrical filter mechanism 6, and is not easy to fall into the inside of the equipment when the cylindrical filter mechanism 6 is taken out.
[0021] Specifically, the cylindrical filter mechanism 6 includes a primary filter cartridge 601, a secondary filter cartridge 602 and a tertiary filter cartridge 603 which are arranged in sequence from the inside to the outside. The diameters of the filter holes on the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 decrease step by step, and the electrolyte waste gas can be filtered step by step, thereby effectively removing dust in the electrolyte waste gas. A lifting rod 604 is fixedly connected to the inner bottom of the tertiary filter cartridge 603, and the lifting rod 604 moves through the secondary filter cartridge 602 and the primary filter cartridge 601 in the vertical direction. A sealing ring 605 located at the top of the sealing partition 5 is detachably sleeved on the upper proximal end of the lifting rod 604. The upper ends of the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 are all in contact with the sealing ring 605, and the gaps between the tops of the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 can be blocked, so that the electrolyte waste gas can only pass through the ring opening of the sealing ring 605 into the primary filter cartridge 601, and then filtered step by step through the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603. In addition, when it is necessary to clean the inside of the cylindrical filter mechanism 6, the filter mechanism can be lifted upward by the lifting rod 604.
[0022] The bottom of the primary filter cartridge 601 and the secondary filter cartridge 602 are fixedly connected with a connecting sleeve 8 that is movably sleeved on the lifting rod 604, and the lower end of each connecting sleeve 8 is fixedly connected with a supporting ring 9, which can assist in supporting the primary filter cartridge 601 or the secondary filter cartridge 602 through the cooperation of the connecting sleeve 8 and the supporting ring 9, so that when the lifting rod 604 is lifted upward, the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 can be driven to move upward. The inner ring of each connecting sleeve 8 is fixedly connected with a first sealing ring 10 that fits the lifting rod 604, which can seal the intersection, so that the electrolyte waste gas can only be filtered and discharged after being discharged through the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 in sequence.
[0023] Furthermore, an inspection cover 11 is connected to the top of the inspection port 7 by bolts, and a limiting groove 12 adapted to the lifting rod 604 is integrally formed on the inspection cover 11, and the top of the lifting rod 604 can be movably inserted into the limiting groove 12, thereby limiting the position of the lifting rod 604; a second sealing ring 13 that fits the sealing partition 5 is fixedly connected to the bottom of the sealing ring 605. When the inspection cover 11 is covered, the limiting groove 12 is sleeved on the lifting rod 604, thereby preventing the lifting rod 604 from moving upward, so that the sealing ring 605 can press the second sealing ring 13 to seal the junction between the sealing ring 605 and the sealing partition 5, thereby preventing the electrolyte waste gas from entering each filter cartridge through the junction.
[0024] Specifically, the upper proximal end of the lifting rod 604 is fixedly connected with a fixing sleeve 14 through screws, and the fixing sleeve 14 is sleeved on the lifting rod 604. A plurality of connecting rods 15 are fixedly connected between the outer ring of the fixing sleeve 14 and the inner ring of the blocking ring 605, and the connecting rods 15 are arranged at intervals along the circumferential direction, so that the blocking ring 605 and the fixing sleeve 14 can be fixedly connected, and at the same time, the electrolyte waste gas does not affect the passing of the ring opening of the blocking ring 605; the blocking ring 605 is detachably connected to the lifting rod 604 through the cooperation of the fixing sleeve 14 and the connecting rod 15. After taking out the cylindrical filter mechanism 6, the screws can be removed to move the fixing sleeve 14 upward and separate it from the lifting rod 604, thereby driving the blocking ring 605 away from the filter cartridges of each level. Since the primary filter cartridge 601 and the secondary filter cartridge 602 are mounted on the lifting rod 604, after removing the sealing ring 605, the primary filter cartridge 601 and the secondary filter cartridge 602 can be directly pulled out upwards, thereby separating the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603, and each filter cartridge can be cleaned separately.
[0025] In addition, the bottom of the blocking ring 605 is fixedly connected with an annular positioning groove 16 adapted to the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 respectively, and the upper ends of the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 can be respectively inserted into the corresponding annular positioning groove 16, so as to position the upper ends of the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603. The upper ends of the primary filter cartridge 601, the secondary filter cartridge 602 and the tertiary filter cartridge 603 are all fixedly connected with a third sealing ring 17 that fits the blocking ring 605, which can seal the intersection of the filter cartridge and the blocking ring 605 to prevent the electrolyte waste gas from passing through the intersection.
[0026] Preferably, the sealing baffle 5 is integrally formed with a mounting groove 18, and the blocking ring 605 is embedded in the mounting groove 18, so that the top surface of the sealing baffle 5 is relatively flat, reducing dead angles, and dust in the electrolyte waste gas is not easy to accumulate in the dead angles. The upper end surface of the blocking ring 605 is tapered with a wide top and a narrow bottom, which facilitates the electrolyte waste gas to pass through the ring opening of the blocking ring 605.
[0027] In this embodiment, since the electrolyte waste gas contains fluorine, the components in the device such as the filter tank 1, the guide plate 4, the sealing partition 5, the cylindrical filter mechanism 6, etc. need to be made of corrosion-resistant materials or undergo anti-corrosion treatment. In addition, it should be noted that the filter cartridges at all levels all adopt a cylindrical structure composed of a filter bag and a frame, which is a prior art and will not be described in detail here.
[0028] When in use, the electrolyte waste gas enters the filter tank 1 through the air inlet 2, and then flows to the top of the filter tank 1 under the action of the guide plate 4 and the sealing partition 5, and then enters the cylindrical filter mechanism 6 from top to bottom. The electrolyte waste gas is subjected to multiple filtrations by the cylindrical filter mechanism 6, and the filtered electrolyte waste gas is discharged through the air outlet 3.
[0029] When the cylindrical filter mechanism 6 needs to be cleaned, the inspection cover 11 is opened, and the lifting rod 604 is lifted upward to take out the cylindrical filter mechanism 6. Since the filter mechanism is cylindrical, the dust in the cylindrical filter mechanism 6 is not easy to fall into the interior of the device.
[0030] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
