Description

Technical Field

[0001] This utility model relates to the field of electrolyte tail gas treatment technology, and in particular to an electrolyte tail gas condensation treatment device. Background Technology

[0002] Lithium batteries have advantages such as small size, light weight, high discharge voltage, and high specific energy. As demand continues to expand, the requirements for their production process are becoming increasingly stringent. Lithium battery electrolytes generally include lithium salts, organic solvents, and additives. During their preparation and solvent transfer, organic exhaust gases are often generated due to poor temperature control or other reasons. During the nitrogen feeding process, these organic exhaust gases mix into the nitrogen gas and are not easily detected. If they are ultimately emitted directly with the nitrogen gas, they may directly cause air pollution.

[0003] A tail gas treatment device for lithium battery electrolyte production, disclosed in CN209422999U, includes a tail gas inlet, a treatment box, a tail gas outlet, and a waste liquid tank. The treatment box includes a fixed position, a coil, a support leg, a coolant inlet, and a coolant outlet. The tail gas inlet pipe is fixedly connected to one end of a connecting pipe via threads, grooves, or flanges.

[0004] The packing material in the above-mentioned device will undergo qualitative changes after long-term use and needs to be replaced. However, when replacing the packing material through the packing inlet, the coil has a bent part, which requires the use of special tools to remove and refill it. The operation is cumbersome and brings inconvenience to the regular replacement of the packing material. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing technologies cannot easily replace the packing material in electrolyte tail gas treatment equipment, resulting in the need for special tools and cumbersome operation during replacement. Therefore, this invention proposes an electrolyte tail gas condensation treatment equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrolyte tail gas condensation treatment device includes a treatment box and two horizontal pipes. A set of packing tubes is installed inside the treatment box. Each packing tube has two leak-proof mechanisms inside. A set of mounting through holes is opened inside each of the two horizontal pipes. A set of rubber sleeves is installed on the inner wall of each mounting through hole. The end of each packing tube is inserted into the mounting through hole and abuts against the rubber sleeve. Two mounting plates are fixedly connected to the outer surface of each packing tube. Each mounting plate has a limit mechanism inside. A set of combined tongue plates is fixedly connected to the side of the two horizontal pipes that are close to each other. A synchronization plate is provided on the side of the two horizontal pipes that are close to each other.

[0008] Preferably, the leak-proof mechanism includes a packing barrier mesh plate, the outer surface of which is threaded to a packing pipe, a connecting rod is fixedly connected to one side of the packing barrier mesh plate, and a hand-tightening plate is fixedly connected to one end of the connecting rod.

[0009] Preferably, the limiting mechanism includes a limiting tongue plate, and the mounting plate has a first limiting slot and a second limiting slot inside. The inner wall of the first limiting slot is slidably connected to the combined tongue plate, the outer surface of the limiting tongue plate is in contact with the combined tongue plate, the outer surface of the limiting tongue plate is slidably connected to the second limiting slot, and a pull rod is fixedly connected to one side of the limiting tongue plate. The outer surface of the pull rod is slidably connected to the second limiting slot.

[0010] Preferably, one end of the pull rod is fixedly connected to a pull plate, and each pull plate is fixedly connected to a synchronization plate.

[0011] Preferably, a spring is sleeved on the outer surface of the pull rod, and the two ends of the spring are fixedly connected to the inner sidewalls of the limiting tongue plate and the second limiting slot, respectively.

[0012] Preferably, coolant inlets are installed on both the left and right sides of the processing box.

[0013] Preferably, each of the two horizontal pipes has a set of vents inside, and one end of each of the two horizontal pipes is connected to an exhaust port.

[0014] Compared with the prior art, the present invention provides an electrolyte tail gas condensation treatment device, which has the following beneficial effects;

[0015] 1. This utility model uses a limiting structure that links a synchronous plate, a pull plate, a pull rod, and a limiting tongue plate. Pulling the synchronous plate releases the limiting of the combined tongue plate and the mounting plate, making it easy to remove the horizontal pipe. With the help of a hand-tightening plate and a connecting rod, the packing barrier mesh plate and the packing pipe threads can be disassembled and assembled. The packing can be replaced without special tools, solving the problem of cumbersome packing replacement operations in the prior art.

[0016] 2. The present invention has a multi-channel treatment structure formed by a set of packing tubes in the overtreatment box. Combined with the circulating coolant introduced by the coolant inlet, it enhances the condensation effect of organic exhaust gas. At the same time, the rubber sleeve ensures the seal between the packing tube and the horizontal through pipe, reduces exhaust gas leakage, and improves the efficiency and stability of exhaust gas treatment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-5 An electrolyte tail gas condensation treatment device includes a treatment box 1 and two horizontal pipes 3. A set of packing pipes 2 are installed inside the treatment box 1. The packing pipes 2 are filled with packing material, which can be activated carbon or activated alumina.

[0026] Each packing tube 2 is equipped with two leak-proof mechanisms inside, which can prevent packing from overflowing. The leak-proof mechanism includes a packing barrier mesh plate 6. The outer surface of the packing barrier mesh plate 6 is threaded to the packing tube 2. A connecting rod 7 is fixedly connected to one side of the packing barrier mesh plate 6. A hand-tightening plate 8 is fixedly connected to one end of the connecting rod 7. The threaded connection and hand-tightening operation make it easy to quickly install and remove the packing barrier mesh plate 6.

[0027] The interior of each of the two horizontal through pipes 3 is provided with a set of installation through holes 4. Each installation through hole 4 is fitted with a set of rubber sleeves 5. The end of each packing tube 2 is inserted into the interior of the installation through hole 4 and abuts against the rubber sleeves 5. The rubber sleeves 5 can buffer the contact pressure and improve the airtightness of the interface.

[0028] Coolant inlets 19 are installed on both the left and right sides of the processing box 1. The two coolant inlets 19 are connected to the coolant cooler through coolant pipes. The coolant circulation can be achieved through the dual-port design to ensure uniform condensation. A set of vents 18 is opened inside the two horizontal pipes 3. One end of the two horizontal pipes 3 is connected to the exhaust port 20. The vents 18 guide the exhaust gas. One exhaust port 20 is connected to the exhaust gas inlet, and the other exhaust port 20 is connected to the external gas-liquid separation and storage device.

[0029] Two mounting plates 9 are fixedly connected to the outer surface of each packing tube 2. Each mounting plate 9 has a limiting mechanism inside, including a limiting tongue plate 13. The mounting plate 9 has a first limiting slot 10 and a second limiting slot 11. A set of combined tongue plates 12 is fixedly connected to the side of each of the two horizontally arranged tubes 3 that are close to each other. The inner wall of the first limiting slot 10 is slidably connected to the combined tongue plate 12. The outer surface of the limiting tongue plate 13 contacts the combined tongue plate 12. The arc-shaped surfaces of the limiting tongue plate 13 and the combined tongue plate 12 are as follows: Figure 4 As shown, this allows the limiting tongue plate 13 to push the combined tongue plate 12 open.

[0030] The outer surface of the limiting tongue plate 13 is slidably connected to the second limiting slot 11. A pull rod 14 is fixedly connected to one side of the limiting tongue plate 13. The outer surface of the pull rod 14 is slidably connected to the second limiting slot 11. The sliding fit structure can reduce friction and extend the service life of the component.

[0031] Both horizontal pipes 3 are equipped with a synchronization plate 16 on their adjacent sides. One end of the pull rod 14 is fixedly connected to a pull plate 15. Each pull plate 15 is fixedly connected to the synchronization plate 16. The synchronization plate 16 can link multiple sets of pull rods 14 to achieve synchronous operation and save time.

[0032] A spring 17 is fitted onto the outer surface of the pull rod 14, and the spring 17... Figure 4 In the natural state, the two ends of the spring 17 are fixedly connected to the inner sidewalls of the limiting tongue plate 13 and the second limiting slot 11, respectively. The elastic force of the spring 17 can automatically reset the limiting tongue plate 13 to ensure the stability of the limiting position.

[0033] Working principle: The inlet and outlet pipes of the coolant are connected to the two coolant ports 19 of the treatment tank 1, respectively, so that the coolant forms a circulation channel inside the treatment tank 1, providing a continuous condensation environment for the packing tube 2. The tail gas source of the electrolyte to be treated is connected to one of the tail gas ports 20, and the tail gas port 20 on the other side is connected to the gas-liquid separation and storage device. The tail gas of the electrolyte containing organic components, including nitrogen carrier, enters the corresponding horizontal pipe 3 through the connected tail gas port 20. With the cooperation of the air inlet 18 on the horizontal pipe 3, it enters each packing tube 2 in sequence.

[0034] In the packed tube 2, the organic components in the exhaust gas are adsorbed by the packing material inside the tube, and condensed by the low temperature of the circulating coolant in the treatment tank 1 to form liquid organic components. Nitrogen gas is difficult to condense and is not adsorbed by the packing material, so it continues to move with the airflow and is discharged into the gas-liquid separation and storage device from the exhaust gas port 20 on the other side. The liquid organic components are deposited at the bottom of the storage device due to gravity, while the nitrogen gas is discharged from the gas phase outlet of the storage device, thus completing the exhaust gas purification.

[0035] Pull the synchronous plate 16, which drives the pull plate 15 and pull rod 14 to slide along the second limiting slot 11, causing the limiting tongue plate 13 to disengage from the combined tongue plate 12 and release the limit. At this time, the spring 17 is compressed, removing the horizontal through pipe 3 and causing the end of the packing tube 2 to disengage from the installation through hole 4. At the same time, the rubber sleeve 5 loses its sealing contact. Tighten the hand-tightening plate 8, which drives the packing barrier mesh plate 6 to rotate out along the inner wall of the packing tube 2 through the connecting rod 7. Remove the old packing and install the new packing. Then, twist the hand-tightening plate 8 in the opposite direction to reset the threaded connection between the packing barrier mesh plate 6 and the packing tube 2, restoring the seal.

[0036] Align each of the combined tongue plates 12 of the horizontal through-pipe 3 with the first limiting slot 10 and insert them. The combined tongue plate 12 pushes the limiting tongue plate 13 to compress the spring 17. When the combined tongue plate 12 is fully in place, the spring 17 resets and pushes the limiting tongue plate 13 to abut against the combined tongue plate 12, thus completing the limiting fixation. At the same time, the end of the packing tube 2 is inserted into the installation through hole 4 and abuts against the rubber sleeve 5 to seal, thus completing the replacement of the packing.
