Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a battery decomposition waste gas treatment device. Background Technology

[0002] Battery decomposition refers to the process of effectively recycling and reusing waste batteries. It has important significance for resource conservation and environmental protection. Since waste batteries contain toxic and harmful substances, direct disposal will impact the environment. However, by adopting scientific decomposition processes, useful resources can be recovered, reducing environmental pollution. The battery decomposition process generally includes the following steps: disassembly; crushing; sorting; chemical dissolution; and material separation. The battery decomposition process may generate harmful gases, liquids, and solid wastes, which may pollute the surrounding environment. Therefore, it is necessary to take corresponding environmental protection measures and technical means to reduce the degree of pollution.

[0003] When treating waste gas from battery decomposition, a regenerative thermal oxidizer (RTO) is usually used. The RTO oxidizes VOCs into carbon dioxide and water in a high-temperature environment and releases a large amount of heat to ensure that the waste gas meets emission standards.

[0004] However, in existing systems where the intake and exhaust pipes are directly connected, the temperature inside the incinerator is not high enough when the organic waste gas first enters through the intake pipe. As a result, the waste gas entering the incinerator is not fully combusted, which may cause some of the organic waste gas entering through the intake pipe to bypass the combustion chamber and be discharged directly through the exhaust pipe without being purified, causing environmental pollution. In order to prevent organic waste gas from being discharged through the exhaust pipe, a battery decomposition waste gas treatment device is provided. Utility Model Content

[0005] The purpose of this invention is to provide a battery decomposition waste gas treatment device in order to prevent organic waste gas from being discharged through the exhaust pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery decomposition waste gas treatment device, comprising two furnace bodies, with a furnace head fixedly connected to the top of each of the two furnace bodies, and an air inlet and an exhaust outlet fixedly connected to the outer walls of each of the two furnace bodies. An air inlet pipe is fixedly connected to one end of the air inlet, and an exhaust pipe is fixedly connected to one end of the exhaust outlet. A chimney is fixedly connected to one end of the exhaust pipe, and the waste gas entering the exhaust pipe is returned to the air inlet pipe through a reflux mechanism.

[0007] The reflux mechanism includes a connecting pipe, which is fixedly connected to the outer wall of the exhaust pipe. One end of the connecting pipe is connected to the intake pipe. A mounting base is provided below the exhaust pipe. A first rotating plate is rotatably connected to the inner wall of the exhaust pipe. The first rotating plate is used to switch the exhaust pipe on and off. A second rotating plate is rotatably connected to the inner wall of the connecting pipe. The switching states of the first rotating plate and the second rotating plate are switched by a switching unit.

[0008] As a further embodiment of this utility model: the switching unit includes a first connecting shaft, which is fixedly connected to the bottom end of the first rotating plate. A first spur gear is fixedly connected to the bottom end of the first connecting shaft. A second connecting shaft is fixedly connected to the bottom end of the second rotating plate. A second spur gear is fixedly connected to the bottom end of the second connecting shaft. Both the first spur gear and the second spur gear are rotatably connected to the interior of the mounting base. A gear rod is slidably connected inside the mounting base. A motor is mounted on the outer wall of the mounting base. The output end of the motor is connected to a threaded rod extending into the interior of the gear rod.

[0009] As a further improvement of this utility model: an air intake fan and a filter are installed on the outer wall of the air intake pipe, and the filter is located at the front end of the air intake fan.

[0010] As a further embodiment of this utility model: the outer wall of the second rotating plate is in contact with the inside of the connecting pipe, and the outer wall of the first rotating plate is in contact with the inner wall of the exhaust pipe.

[0011] As a further improvement of this utility model: one end of the toothed rod is provided with a threaded hole, and the threaded hole matches the threaded rod.

[0012] As a further improvement of this utility model: the mounting base has a movable groove inside, and the inner wall of the movable groove fits against the outer wall of the toothed rod.

[0013] As a further embodiment of this utility model: the outer wall of the gear rack is provided with a tooth groove, and both the second spur gear and the first spur gear mesh with the tooth groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a reflux mechanism, when the exhaust gas is initially burned, the motor drives the exhaust pipe to close and the connecting pipe to open. At this time, when the exhaust gas enters the exhaust pipe through the exhaust port, it will again enter the intake pipe through the connecting pipe, and then enter the furnace body and burner head again for combustion. The refluxed exhaust gas will also heat the newly entered exhaust gas, improving the preheating effect. After combustion for a period of time, the exhaust pipe is opened and the connecting pipe is closed, and the exhaust gas can enter the chimney through the exhaust pipe for discharge. This helps to prevent organic waste gas from entering the chimney through the exhaust pipe and causing environmental pollution. Attached Figure Description

[0022] Please see Figures 1-4In this embodiment of the utility model, a battery decomposition waste gas treatment device includes two furnace bodies 1. The top of the two furnace bodies 1 is fixedly connected to a furnace head 2. The outer walls of the two furnace bodies 1 are fixedly connected to an air inlet 3 and an exhaust outlet 5. One end of the air inlet 3 is fixedly connected to an air inlet pipe 4, and one end of the exhaust outlet 5 is fixedly connected to an exhaust pipe 6. One end of the exhaust pipe 6 is fixedly connected to a chimney 10. The waste gas entering the exhaust pipe 6 is returned to the air inlet pipe 4 through a return mechanism 7. An air intake fan 8 and a filter 9 are installed on the outer wall of the air intake pipe 4. The filter 9 is located at the front end of the air intake fan 8.

[0023] In this embodiment: the blower 8 operates to drive the exhaust gas into the furnace body 1 through the air inlet pipe 4 and the air inlet 3. The filter 9 filters the dust in the exhaust gas. The exhaust gas enters from the air inlet 3 on one furnace body 1 and exits from the exhaust outlet 5 on another furnace body 1. It flows into the chimney 10 through the exhaust pipe 6 and is then discharged through the chimney 10.

[0024] Please refer to this carefully. Figures 1-4 The return flow mechanism 7 includes a connecting pipe 701, which is fixedly connected to the outer wall of the exhaust pipe 6. One end of the connecting pipe 701 is connected to the intake pipe 4. A mounting base 702 is provided below the exhaust pipe 6.

The second spur gear 708 drives the second connecting shaft 707 to rotate, which in turn drives the second rotating plate 706 to rotate. The first rotating plate 703 closes the exhaust pipe 6, while the second rotating plate 706 opens the connecting pipe 701. At this time, when the exhaust gas enters the exhaust pipe 6 through the exhaust port 5, it will again enter the intake pipe 4 through the connecting pipe 701. It will then enter the furnace body 1 and the burner head 2 again through the intake pipe 4 and the intake port 3 for combustion. The returned exhaust gas will also heat the newly entered exhaust gas, improving the preheating effect.

[0026] After combustion for a period of time, the starting motor 711 drives the first rotating plate 703 and the second rotating plate 706 to rotate. The rotation of the first rotating plate 703 opens the exhaust pipe 6, and the rotation of the second rotating plate 706 closes the connecting pipe 701. The exhaust gas can enter the chimney 10 through the exhaust pipe 6 and be discharged, which helps to prevent organic waste gas from entering the chimney 10 through the exhaust pipe 6 and being discharged, causing environmental pollution.
