[0002] In the production process of lithium (sodium) batteries, multiple production steps are required, including electrode sheet manufacturing, battery synthesis, formation, and packaging. When producing the positive electrode material, a sintering process is usually used to process the material to change its physical and chemical properties to meet the production requirements. Tail gas containing VOCS (Volatile Organic Compounds) such as hydrocarbons and carbon oxides is generated during the sintering process, and the tail gas needs to be incinerated to meet the emission standards.

Therefore, it should not be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0027] Refer to Figure 1The utility model provides a tail gas incinerator, including a furnace body 1, a burner 2, and a heat exchanger 3. The furnace body 1 is connected with an input pipe 11 for conveying tail gas into the furnace body 1 and an air supply pipe (not shown in the figure) for conveying combustion-supporting gas into the furnace body 1. The furnace body 1 is provided with an output port 13 for discharging the incinerated tail gas to the outside of the furnace body 1; the burner 2 is arranged inside the furnace body 1 for incinerating the tail gas; the heat exchanger 3 is connected with the furnace body 1 through the output port 13, and is used to convey the heat carried by the tail gas to the heat exchanger 3. The end of the input pipe 11 away from the furnace body 1 is connected with the output end of the heat exchanger 3, and is used to convey the tail gas to the furnace body 1 through the heat exchanger 3 for incineration.

[0028] Among them, the furnace body 1 extends in the horizontal direction, and an input port 12 is opened at one end of the furnace body 1. The output end of the input pipe 11 is connected with the inside of the furnace body 1 through the input port 12, which is used to transport the exhaust gas to be incinerated to the inside of the furnace body 1. The air supply pipe is connected to one end of the furnace body 1, and the output port 13 is opened at the end of the furnace body 1 away from the air supply pipe; the heat exchanger 3 is detachably arranged at the end of the furnace body 1 where the output port 13 is opened; the combustion-supporting gas is air at room temperature.

[0029] It should be understood that the exhaust gas to be incinerated discharged from the kiln enters the heat exchanger 3, and enters the input pipe 11 through the output end of the heat exchanger 3, and enters the furnace body 1 through the input port 12, and the combustion gas enters the furnace body 1 through the air supply pipe, so that the exhaust gas to be incinerated and the combustion gas are mixed inside the furnace body 1 and incinerated under the action of the burner 2, and the exhaust gas after incineration enters the heat exchanger 3 through the output port 13, transfers the heat carried to the heat exchanger 3 and then discharges to the outside, the exhaust gas to be incinerated discharged into the heat exchanger 3 and the exhaust gas after incineration that enters the heat exchanger 3 from the output port 13 enter the heat exchanger 3 through different pipes to avoid mixing with each other.

[0030] In this way, the heat carried by the exhaust gas after incineration inside the furnace body 1 can be transferred to the heat exchanger 3, so that the exhaust gas to be incinerated discharged into the heat exchanger 3 through the kiln can be fully preheated by the heat of the heat exchanger 3. The exhaust gas to be incinerated has a higher temperature when entering the furnace body 1 through the inlet 12, which helps to fully incinerate the exhaust gas to be incinerated in the furnace body 1, saving the preheating step and the combustion-supporting gas energy required for preheating. At the same time, since the heat carried by the exhaust gas after incineration is transmitted to the heat exchanger 3, the exhaust gas temperature discharged to the outside is lower, which can save the cooling step of the exhaust gas after incineration and the cooling wind energy, reduce energy consumption, and improve the heat utilization rate of the exhaust gas after incineration.

[0031] It can be understood that valves can be set on the input pipeline 11 and the air supply pipeline so that the content of the exhaust gas to be incinerated and the combustion-supporting gas delivered to the heat exchanger 3 can be flexibly adjusted according to the incineration conditions inside the furnace body 1, so as to avoid insufficient incineration and improve the incineration efficiency; further, fans can be set on the input pipeline 11 and the air supply pipeline to drive the gas flow.

[0032] Refer to Figure 1 Figure 1 , in some embodiments, the heat exchanger 3 is connected to an intake pipe 31. The intake pipe 31 communicates with the input end of the heat exchanger 3 and is used to convey tail gas to the heat exchanger 3. In this embodiment, one end of the intake pipe 31 is arranged at the bottom of the heat exchanger 3, and the other end is connected to a kiln that generates tail gas. The end of the input pipe 11 away from the furnace body 1 is arranged at the top of the heat exchanger 3.

[0033] In this way, the tail gas to be incinerated generated in the kiln enters the bottom of the heat exchanger 3 through the intake pipe 31, and the tail gas flows from the bottom to the top of the heat exchanger 3, which can extend the residence time of the tail gas in the heat exchanger 3, enable the heat exchanger 3 to fully preheat the tail gas to be incinerated, improve the heat utilization rate of the incinerated tail gas, and save energy.

[0034] It can be understood that a blower can also be arranged on the intake pipe 31 to drive the tail gas into the interior of the heat exchanger 3, which will not be elaborated here.

[0035] Refer to Figure 1 Figure 1 , in some embodiments, a first incineration chamber 14 is formed inside the furnace body 1, and the burner 2 is arranged in the first incineration chamber 14. Further, the input port 12 communicates with the first incineration chamber 14, and the air supplement pipe is arranged below the input port 12.

[0036] Among them, one burner 2 is arranged in the first incineration chamber 14. The burner 2 is arranged at the top end of the first incineration chamber 14, and the input port 12 is arranged on the side of the furnace body 1 facing the burner 2.

[0037] In this way, after the tail gas to be incinerated is preheated by the heat exchanger 3, it can be conveyed to the lower part of the burner 2 through the input port 12, reducing the heat loss generated during the process of conveying the preheated tail gas to the interior of the furnace body 1, improving the combustion efficiency, and saving energy.

[0038] Refer to Figure 1 Figure 1 , in some embodiments, there are multiple burners 2. A second incineration chamber 15 communicating with the first incineration chamber 14 is formed inside the furnace body 1. The second incineration chamber 15 is arranged downstream of the first incineration chamber 14, and at least one burner 2 is arranged in each of the first incineration chamber 14 and the second incineration chamber 15.

[0039] In this embodiment, the second incineration chamber 15 is arranged on the side of the first incineration chamber 14 facing the heat exchanger 3, and one burner 2 is arranged at the bottom of the second incineration chamber 15.

[0040] In this way, the exhausted gas incinerated in the first incineration chamber 14 enters the second incineration chamber 15 for continuous incineration. This can enable the exhausted gas to be fully incinerated, reduce the VOCS components in the exhausted gas discharged to the outside, improve the incineration effect. Since the exhausted gas to be incinerated conveyed into the furnace body 1 has a relatively high temperature, it can save the energy consumed by the burners 2 in the first incineration chamber 14 and the second incineration chamber 15 during incineration and reduce energy waste.

[0041] It can be understood that the installation positions and quantities of the burners 2 in the first incineration chamber 14 and the second incineration chamber 15 can be adjusted according to actual needs, as long as the combustion efficiency of the exhausted gas inside the furnace body 1 can be improved, and no more examples will be listed here.

[0042] Refer to Figure 1 , in some embodiments, a conveying chamber 16 is provided inside the furnace body 1. The conveying chamber 16 is arranged downstream of the second incineration chamber 15. The output port 13 is arranged at one end of the furnace body 1 where the conveying chamber 16 is provided. The first incineration chamber 14, the second incineration chamber 15, and the conveying chamber 16 are arranged in sequence along the length direction of the furnace body 1.

[0043] In this embodiment, the conveying chamber 16 is arranged on the side of the second incineration chamber 15 facing the heat exchanger 3. The output port 13 is arranged at the bottom of the conveying chamber 16 and is communicated with the conveying chamber 16, and is used for discharging the incinerated exhausted gas into the heat exchanger 3.

[0044] In this way, after the exhausted gas to be incinerated is fully incinerated through the first incineration chamber 14 and the second incineration chamber 15, it is discharged into the conveying chamber 16 for buffering and then discharged into the heat exchanger 3 through the output port 13. This can make the incinerated exhausted gas more stable during the process of being discharged into the heat exchanger 3, the heat transferred to the heat exchanger 3 more uniform, and improve the heat utilization rate of the incinerated exhausted gas.

[0045] It can be understood that the position of the output port 13 on the furnace body 1 can be flexibly adjusted according to the actual situation, and is not limited to the bottom of the furnace body 1, and no more examples will be listed here.

[0046] Refer to Figure 1 , in some embodiments, the furnace body 1 is connected with at least one partition 17. The partition 17 is arranged inside the furnace body 1 and divides the furnace body 1 into the first incineration chamber 14, the second incineration chamber 15, and the conveying chamber 16. Exhaust holes 171 are provided on the partition 17 to communicate the first incineration chamber 14, the second incineration chamber 15, and the conveying chamber 16. Along the direction perpendicular to the arrangement direction of the first incineration chamber 14, the second incineration chamber 15, and the conveying chamber 16, the exhaust holes 171 are arranged staggeredly.

[0047] In this embodiment, two partitions 17 are provided, and the two partitions 17 are arranged at equal intervals along the length direction of the furnace body 1. The exhaust holes 171 opened on the partition 17 for separating the first incineration chamber 14 and the second incineration chamber 15 are arranged near the bottom of the furnace body 1, and the exhaust holes 171 opened on the partition 17 for separating the second incineration chamber 15 and the conveying chamber 16 are arranged near the top of the furnace body 1.

[0048] In this way, after the preheated exhaust gas to be incinerated enters the first incineration chamber 14 through the input port 12, it flows in the direction close to the output port 13 through the exhaust holes 171 in sequence inside the furnace body 1, which can extend the flow path of the exhaust gas in the furnace body 1, so that the exhaust gas can be fully burned in the furnace body 1, reducing VOCS residue, so that the heat generated by the combustion can be fully transported to the heat exchanger 3, and the heat utilization rate of the exhaust gas after incineration is improved.

[0049] See also Figure 1 In some embodiments, the heat exchanger 3 is connected to an exhaust pipe 32, which is connected to the output port 13 and is used to discharge the exhaust gas passing through the heat exchanger 3 to the outside. Furthermore, one end of the exhaust pipe 32 away from the output port 13 is connected to the outside.

[0050] In this way, the temperature of the exhaust gas after incineration is reduced after the heat is transferred to the heat exchanger 3, and the exhaust gas after heat exchange can be directly discharged into the atmosphere through the exhaust pipe 32, saving the step of introducing cooling air to cool the exhaust gas, saving energy and improving the heat utilization rate of the exhaust gas after incineration.

[0051] It is understandable that a valve may also be provided on the exhaust pipe 32 to control the communication between the exhaust pipe 32 and the furnace body 1 .

[0052] See also Figure 1 In some embodiments, the output end of the exhaust pipe 32 is connected to an exhaust fan 6 for driving the exhaust gas in the exhaust pipe 32 to be discharged to the outside. In this embodiment, the exhaust pipe 32 is connected to the exhaust fan 6 through a pipeline.

[0053] It is understandable that the output end of the exhaust pipe 32 may also be connected to an air pump and is not limited to the exhaust fan 6. The structure for driving the exhaust gas flow may be adjusted according to actual needs and will not be listed in detail here.

[0054] See also Figure 1 In some embodiments, the tail gas incinerator further includes a pressure gauge 4, and two pressure gauges 4 are provided. The two pressure gauges 4 are respectively provided in the second incineration chamber 15 and between the exhaust pipe 32 and the exhaust fan 6. In this embodiment, the pressure gauge 4 provided in the second incineration chamber 15 is located at the end of the second incineration chamber 15 away from the burner 2.

[0055] Further, see Figure 1, the tail gas incinerator further includes three temperature controllers 5, which are respectively arranged in the first incineration chamber 14, the second incineration chamber 15, and between the exhaust pipe 32 and the exhaust fan 6. In this embodiment, the temperature controllers 5 arranged in the first incineration chamber 14 and the second incineration chamber 15 are respectively arranged opposite to the corresponding burners 2.

[0056] In this way, by observing the pressure gauge 4 and the temperature controller 5, the incineration condition of the tail gas inside the furnace body 1 can be judged, and then the intake air volume of the tail gas or the intake air volume of the combustion-supporting gas can be adjusted to improve the combustion efficiency of the tail gas inside the furnace body 1 and avoid incomplete combustion or energy waste.

[0057] It can be understood that the tail gas incinerator can further include a control module. The pressure gauge 4, the temperature controller 5, and the valves can all be connected to the control module, so that the pressure gauge 4 and the temperature controller 5 can monitor the temperature and pressure at the output ends of the furnace body 1 and the exhaust pipe 32 in real time. The valves arranged in the input pipe 11, the air supplement pipe, and the output pipe are dynamically adjusted through the control module, so that the tail gas inside the furnace body 1 burns fully and conveys heat for preheating the tail gas to be incinerated to the heat exchanger 3, thereby improving the utilization rate of the tail gas heat.

[0058] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
