Description

Technical Field

[0001] This invention relates to the field of waste gas pyrolysis technology, specifically to a device and system for pyrolyzing exhaust gas after high-temperature heat treatment of battery materials. Background Technology

[0002] With the large-scale development of the new energy battery industry, battery roasting exhaust gas treatment devices need to meet three core requirements: First, efficient pretreatment, which requires rapid interception of dust particles and preliminary adsorption of acidic gases to avoid blockage or corrosion of subsequent equipment; second, thorough pyrolysis purification, which requires complete decomposition of organic pollutants (such as dimethyl carbonate and polyvinylidene fluoride decomposition products) into harmless carbon dioxide and other substances at high temperatures (usually 800-1000℃) to ensure that emissions meet standards.

[0003] First, filter bag switching requires machine shutdown, causing interruption of processing: Traditional filter bag filtration devices are mostly designed with "single set of filter bags + fixed pipeline". When too much dust accumulates on the surface of the filter bag, it is necessary to stop the machine to replace the filter bag or clean it. The downtime can be as long as 30-60 minutes. During this period, the roasting exhaust gas needs to be temporarily discharged directly (or stored in a buffer tank with limited capacity). This not only poses environmental risks, but may also cause the roasting process to stop due to the overflow of the buffer tank. Although some multi-set filter bag devices support switching, the old filter bag pipeline needs to be closed and the new filter bag pipeline opened manually during switching. The operation is cumbersome and prone to switching delays, resulting in temporary leakage of exhaust gas. Summary of the Invention

[0020] Preferably, both the first pipe and the second pipe are fixedly connected to a connecting pipe fitting on their outer sides. The connecting pipe fitting is used to allow the first pipe and the second pipe to move synchronously.

[0026] A pyrolysis system for exhaust gas after high-temperature heat treatment of battery materials, comprising:

[0032] Processing unit: Analyzes and processes the temperature information;

[0033] Output unit: Outputs the signals transmitted by the processing unit.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. The pretreatment mechanism of this device can efficiently purify the battery roasting exhaust gas. The acid-resistant filter bags can accurately intercept dust particles in the exhaust gas, while the acid-resistant coating on the surface adsorbs acidic gases, reducing the burden of subsequent pyrolysis. The sealing design of the elastic sealing sheet and the tough sealing gasket can prevent the leakage of unpurified exhaust gas and avoid secondary pollution. In addition, the pipeline can be moved synchronously by the electric push rod, realizing flexible switching of the four filter bag filtration areas. The filter bag function can be changed without stopping the machine, ensuring that the pretreatment process is continuous and uninterrupted, and significantly improving the exhaust gas treatment efficiency.

[0036] 2. The pyrolysis mechanism employs a dynamic adjustment design to ensure the complete decomposition of organic pollutants. A motor-driven gear transmission dynamically adjusts the height and heating range of the heating head. Combined with precise control of the heating outlet by the shielding ring, this ensures that high temperatures are evenly distributed across the exhaust gas. The coordinated operation of opposing components balances the temperature of the chambers on both sides of the pyrolysis furnace, preventing incomplete decomposition of pollutants due to uneven localized temperatures. Simultaneously, insulation reduces heat loss, and elastic pads prevent hot gas leakage, ensuring the high-temperature environment required for pyrolysis while improving energy efficiency and effectively decomposing carbonate organic pollutants in the exhaust gas.

[0037] 3. The intelligent control system equipped with the device enables precise control of the pyrolysis temperature. Temperature sensors collect the internal temperature of the pyrolysis furnace in real time, and the control terminal automatically adjusts the motor's rotation direction based on the temperature data, thereby adjusting the heat outlet area of ​​the heating head: increasing the heating intensity when the temperature is below 800℃ to ensure that pollutants reach the decomposition threshold; reducing the heating intensity when the temperature is above 1000℃ to avoid energy waste and component overheating damage; and maintaining stability within the optimal range of 800-1000℃. This intelligent control not only ensures efficient decomposition of organic pollutants but also achieves energy-saving operation, extends equipment lifespan, and reduces long-term maintenance costs.

[0058] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0059] Please see Figures 1 to 15 The present invention provides a technical solution:

[0060] Example 1: Exhaust gas pretreatment stage.

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the support 21 of the pretreatment mechanism 2 is fixed on the base plate 1, and the top is welded with a treatment drum 22. The top of the treatment drum 22 is bonded with a tough sealing gasket 23, which is made of acid and alkali resistant rubber. The inside is fitted with an internal plate 24, and the internal plate 24 is fixed with an acid resistant filter bag 25, which is made of polytetrafluoroethylene. Elastic sealing sheets 205 are symmetrically bonded to both sides of the treatment drum 22. The center of the drum is welded with pipe 26 and pipe 27 respectively. The two pipes are connected by a connecting pipe fitting 29 to ensure synchronous movement. The ends of the pipes are connected to elastic pipes 28, which are made of corrosion resistant corrugated pipes. Pipe 26 is connected to the exhaust gas source, and pipe 27 is connected to the pyrolysis mechanism 4 through a connecting pipe 3.

[0062] After the exhaust gas treatment is started, the exhaust gas generated by battery roasting first enters the treatment drum 22 through pipe 26. The acid-resistant filter bag 25 intercepts dust particles in the exhaust gas, and the acid-resistant coating on the surface of the filter bag adsorbs acidic gases, completing the initial purification. The elastic sealing sheet 205 and the tough sealing gasket 23 ensure the internal sealing of the treatment drum 22 to prevent leakage of unpurified exhaust gas. If it is necessary to switch the filtration area of ​​the acid-resistant filter bag 25, the electric push rod 20 is activated. It is fixed on the connector on the outside of the treatment drum 22 and pushes the first insert 204 at the output end to move. During the process: the perforated cylinder 203 first wraps the outer pipe 206 outside the second pipe 27. The first insert 204 squeezes the conical head 207 inside the outer pipe 206 and stretches the second spring 208 until the first insert 204 and the second insert 209 inside the outer pipe 206 are engaged. The friction protrusion on the outside of the second insert 209 increases the size of the first insert. The clamping force between the first insert 204 and the second insert 209, and the fact that the first insert 204, during its insertion into the outer tube 206, will push the conical head 207 outward, causing the conical head 207 to pass through the hole on the outside of the perforated cylinder 203, thus locking the outer tube 206 and the perforated cylinder 203 together. The connecting pipe 29 drives the first pipe 26 and the second pipe 27 to move synchronously, switching the exhaust gas to other filter bag areas. There are a total of 4 filter bags in the treatment drum 22, corresponding to 4 moving positions, ensuring continuous filtration. The first slide plate 201 at the output end of the electric push rod 20 slides along the perforated cylinder 203, and the first spring 202 buffers the impact of the engagement, preventing damage to components.

[0063] Example 2: Exhaust gas pyrolysis stage.

[0064] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, the pyrolysis furnace 41 of the pyrolysis mechanism 4 is fixed on the base plate 1. An inlet pipe 42 and an outlet pipe 43 are welded to the outside. The inlet pipe 42 is connected to a connecting pipe 3, while the outlet pipe 43 is connected to the exhaust gas outlet. The outlet pipe 43 is positioned higher than the inlet pipe 42 to ensure sufficient retention of the exhaust gas. An internal heat insulation component 402, made of aluminum silicate insulation cotton, is welded to the inside of the heat insulation component 402. A fourth pipe 407 is welded to the inside of the fourth pipe 407. A second sliding plate 408 with a hollow structure is fitted to the outside of the fourth pipe 407 for hot gas transport and weight reduction. Elastic pads 400 made of high-temperature resistant silicone are bonded to the upper and lower sides of the sliding plate to prevent hot gas from overflowing. The other end of the elastic pad 400 is bonded to the inside of the fourth pipe 407. Two No. 2 limiting plates 409 are welded to the outside of 07 to limit the sliding range of the slide plate; No. 3 pipe 404 is welded to the outside of No. 2 slide plate 408, and a heat head 40A is installed on the outside of No. 3 pipe 404. No. 2 rod 403 is welded to the bottom, and No. 2 inclined block 401 is connected to the top through No. 1 rod 49. No. 1 rod 49 is inserted into the outside of pyrolysis furnace 41. No. 3 spring 40 is welded to the bottom of No. 2 inclined block 401. Its inclined surface is pressed and matched with the No. 1 inclined block 47 at the bottom of No. 2 gear 46 that meshes with No. 1 gear 45 at the output end of motor 44. No. 3 spring 40 is fixed to the outside of pyrolysis furnace 41; No. 3 rod 405 is welded to the bottom of the inner cavity of heat insulation component 402, and a shielding ring 406 is welded to the top corresponding to the position of heat head 40A.

[0065] The pretreated exhaust gas enters the pyrolysis furnace 41 through the feed pipe 42. The motor 44 starts, driving the first gear 45 to rotate, and the second gear 46 rotates synchronously. The first inclined block 47 at the bottom of the motor 45 presses the second inclined block 401, pushing the first rod 49 downward, compressing the third spring 40, and thus driving the third pipe 404 and the heating head 40A to move downward synchronously. The heating head 40A releases high temperature into the exhaust gas, decomposing the carbonate organic pollutants in it. During the downward movement, part of the opening of the heating head 40A is blocked by the shielding ring 406, adjusting the heating range. The second sliding plate 408 slides along the fourth pipe 407, the elastic pad 400 buffers the impact and seals the gap, and the second limiting plate 409 prevents the sliding plate from deviating. After the first inclined block 47 rotates and disengages from the second inclined block 401, the third spring 40 rebounds, driving all components to reset, and the heating head 40A moves upward, fully opening, realizing dynamic adjustment of the heating height and range, ensuring that the high temperature acts evenly on the exhaust gas.

[0066] The opposing component 40B is composed of another set of mechanisms including rod 49, spring 40, inclined block 401, inclined block 47, tube 404, and shielding ring 406. When gear 46 rotates clockwise, it causes tube 404 on one side to move downward and reduces the hot air ejected from the heat outlet 40A. Similarly, when gear 46 rotates counterclockwise, it causes tube 404 on the other side to move downward. Meanwhile, tube 404 on the original side returns to its initial height under the action of spring 40, thus controlling the temperature inside the two cavities of the pyrolysis furnace 41.

[0067] Example 3: Intelligent Control Stage.

[0068] like Figure 9 , Figure 13 , Figure 14 and Figure 15 As shown, during the pyrolysis process, the temperature sensor 40C collects the internal temperature data of the pyrolysis furnace 41 in real time and transmits it to the control terminal receiving unit via signal. The processing unit analyzes the temperature information: if the temperature is below the minimum threshold of 800℃ for the decomposition of organic pollutants, the output unit sends a signal to the motor 44 to rotate counterclockwise, thereby increasing the area of ​​the heat outlet of the heat outlet head 40A and increasing the heating capacity; if the temperature is above 1000℃ to avoid energy waste and component overheating, the motor 44 rotates clockwise, thereby reducing the area of ​​the heat outlet of the heat outlet head 40A and reducing the heating capacity; if the temperature is in the range of 800-1000℃, the motor 44 remains stationary to ensure that the temperature inside the pyrolysis furnace 41 is stable within the optimal range. The shielding ring 406 initially blocks approximately one-quarter of the opening of the heat outlet head 40A.

[0069] The working principle of this invention: In the initial stage of exhaust gas treatment, the pretreatment mechanism 2 first performs dust removal and acid removal treatment on the exhaust gas. Battery exhaust gas enters the treatment drum 22 through the first pipe 26. The acid-resistant filter bag 25 inside the treatment drum 22 intercepts dust particles in the exhaust gas, and at the same time, the acid-resistant material adsorbs acidic substances in the exhaust gas, completing the initial purification. The elastic sealing sheet 205 and the tough sealing gasket 23 ensure the internal sealing of the treatment drum 22 to prevent leakage of unpurified exhaust gas. During the purification process, the electric push rod 20 can drive the first insert 204 to move and engage with the second insert 209 in the outer pipe 206. The friction protrusion on the outside of the second insert 209 enhances the connection stability. The outer side of the output end of the electric push rod 20 is slidably connected to the perforated cylinder 203 through the first sliding plate 201, and the first sliding plate 201 and the perforated cylinder 203 are connected by the first spring 202. The first insert 204 and the second insert 204 are connected by the first spring 202. Before the fitting is completed, the perforated cylinder 203 will wrap around the outer pipe 206. When the first insert 204 and the second insert 209 fit together, the first sliding plate 201 will stretch the first spring 202. In addition, the first insert 204 will push the conical head 207 outward during the movement and stretch the second spring 208 until it is inserted and fitted with the hole on the surface of the perforated cylinder 203. The connecting pipe 29 ensures that the first pipe 26 and the second pipe 27 move synchronously. The pretreated exhaust gas is transported to the pyrolysis mechanism 4 through the second pipe 27, the elastic pipe 28 and the connecting pipe 3. Through the above operations, the first pipe 26 and the second pipe 27 move synchronously to the position of the acid-resistant filter bags 25. There are four acid-resistant filter bags 25. At the same time, the first pipe 26 and the second pipe 27 can move in four directions, which are consistent with the positions of the four acid-resistant filter bags 25.

[0070] During the pyrolysis stage, the pyrolysis mechanism 4 performs deep decomposition of the purified exhaust gas. The exhaust gas enters the pyrolysis furnace 41 through the feed pipe 42. The motor 44 starts and drives the first gear 45 to rotate. The first gear 45 meshes with the second gear 46 for transmission. The second gear 46 drives the first inclined block 47 at the bottom to rotate. The inclined surface of the first inclined block 47 presses against the second inclined block 401, pushing the first rod 49 downward and compressing the third spring 40, which in turn drives the third tube 404 to move downward simultaneously. The heat outlet 40A on the outside of the third tube 404 releases high temperature into the exhaust gas, thermally decomposing the organic pollutants in the exhaust gas. As the third tube 404 and the heat outlet 40A move downward, part of the opening of the heat outlet 40A is blocked by the shielding ring 406. The third spring 40 is compressed when the second inclined block 401 moves downward, and rebounds after the first inclined block 47 rotates and disengages, causing all components to reset, achieving dynamic adjustment of the height and opening of the heat outlet 40A, ensuring that the high temperature acts evenly on the exhaust gas. Simultaneously, the second sliding plate 408 slides along the fourth tube 407, the elastic pad 400 buffers the sliding impact and provides a seal, and the second limiting plate 409 limits the sliding range to prevent the third tube 404 from shifting or disengaging; the heat insulation component 402 reduces heat loss inside the pyrolysis furnace 41.

[0071] The intelligent control system monitors the entire pyrolysis process. Temperature sensor 40C collects real-time temperature data inside the pyrolysis furnace 41 and transmits the signal to the receiving unit of the control terminal. The processing unit analyzes and processes the temperature information. If the temperature is lower than the threshold required for pyrolysis, the output unit sends a signal to motor 44 to adjust the speed of motor 44 to change the heating intensity of the heat outlet 40A. If the temperature is too high, the system adjusts in the opposite direction to ensure that the internal temperature of the pyrolysis furnace 41 is stable within the optimal pyrolysis range, ensuring the decomposition efficiency of organic pollutants and realizing intelligent and precise exhaust gas treatment.

[0072] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
