[0003] In view of the above problems, the present application provides a gas heat exchange device and a battery material processing system, which can improve the heat exchange efficiency of tar in sintering waste gas and increase the condensation recovery rate, thereby reducing its pollution to the environment.
[0004] In a first aspect, the present application provides a gas heat exchange device, including a heat exchange cylinder and a heat exchange assembly. The heat exchange cylinder has a heat exchange cavity, the heat exchange cavity is used to accommodate the gas to be heat exchanged, and a partition plate is provided in the heat exchange cavity, and a gas through hole is provided on the partition plate. The heat exchange assembly is arranged in the heat exchange cavity, the heat exchange assembly has a heat exchange pipe for the flow of heat exchange medium, and the heat exchange assembly is used to heat exchange the gas to be heat exchanged.
[0005] In the technical solution of the embodiment of the present application, the design of the heat exchange chamber enables the gas to flow therein and exchange heat with the heat exchange component. Since the volume of the heat exchange cylinder is large, it provides sufficient flow space for the gas, so that the gas can fully contact the heat exchange component during the flow process, thereby extending the time of gas heat exchange. A partition plate is arranged in the heat exchange cylinder, and a gas through hole is arranged on the partition plate. The above structure can extend the flow path of the gas in the heat exchange chamber and improve the heat exchange efficiency. In addition, the heat exchange component is located in the heat exchange chamber, and the design of the heat exchange pipeline enables the heat exchange medium to flow therein and exchange heat with the gas to be heat exchanged. Therefore, the design of the gas heat exchange equipment fully considers the flow characteristics and heat exchange requirements of the gas. By increasing the flow space of the gas, extending the heat exchange time and optimizing the structure of the heat exchange component, this equipment can effectively improve the heat exchange efficiency, reduce the risk of clogging the gas pipeline after the tar in the gas condenses, and improve the stability of the heat exchange.
[0006] In some embodiments, the volume occupied by the heat exchange assembly in the heat exchange cavity is less than or equal to half of the total volume of the heat exchange cavity. In the above structure, the volume of the heat exchange cavity is increased, the risk of gas condensation and clogging the heat exchange cavity is reduced, and the efficiency of heat exchange and the stability of the transposition process are improved.
[0007] In some embodiments, the heat exchange cylinder includes a cylinder body and a medium container. A gas outlet and a gas inlet communicating with the heat exchange cavity are provided on the cylinder wall of the cylinder body. The medium container is connected to one end of the cylinder body. The medium container is provided with a medium outlet and a medium inlet. The medium container is used to accommodate a heat exchange medium. The medium inlet is communicated with the inlet of the heat exchange component, and the medium outlet is communicated with the outlet of the heat exchange component. In the above structure, the gas outlet and the gas inlet are provided on the cylinder wall of the cylinder body, which facilitates the gas to enter the heat exchange cavity for heat exchange. Moreover, the connection between the medium container and the cylinder body improves the convenience of the heat exchange medium entering the heat exchange component and enhances the heat exchange efficiency.
[0008] In some embodiments, a condensation outlet is provided at one end of the cylinder body far from the medium container. In the above structure, by arranging the condensation outlet opposite to the medium container, the components can be reasonably arranged, the condensed tar can be collected at the condensation outlet by gravity, and it is convenient for the heat exchange medium in the medium container to enter the cylinder body.
[0009] In some embodiments, the medium container includes a containing shell and a partition plate. The containing shell has a containing cavity. The partition plate is arranged inside the containing shell. The partition plate divides the containing cavity into a first cavity and a second cavity. The medium inlet is communicated with the first cavity, and the medium outlet is communicated with the second cavity. In the above structure, by arranging the partition plate in the containing shell, the heat exchange medium is divided into two different flow paths in the containing cavity. This division helps to avoid the direct short circuit of the medium inside the container, ensures that the medium can fully flow through the heat exchange pipes of the heat exchange component, and thus improves the heat exchange efficiency. Moreover, the medium inlet and the medium outlet are respectively communicated with the first cavity and the second cavity, which makes the connection structure between the medium container and the heat exchange component more concise and clear. This not only simplifies the assembly and maintenance processes of the equipment, but also helps to reduce the manufacturing cost of the equipment.
[0010] In some embodiments, a liquid outlet and a liquid inlet are further provided on the containing shell. The liquid inlet is communicated with the first cavity and is arranged opposite to the medium inlet. The liquid outlet is communicated with the second cavity and is arranged opposite to the medium outlet. In the above structure, the liquid inlet is arranged opposite to the medium inlet to ensure that the medium can directly enter the heat exchange component from the first cavity. Similarly, the liquid outlet is arranged opposite to the medium outlet, enabling the medium to smoothly flow from the heat exchange component to the second cavity. Moreover, the liquid inlet and the liquid outlet are directly connected to the internal cavity of the containing shell, reducing the leakage risk of the medium during the transmission process.

The first flange is arranged on the outer periphery of the cylinder, the second flange is arranged on the outer side of the containment shell away from the containment cavity, and the fastener is detachably connected to the first flange and the second flange. The above structure realizes a detachable connection between the containment shell and the cylinder by setting a connection assembly, which improves the convenience of connecting the containment shell and the cylinder and the assembly efficiency on the basis of ensuring the shell and sealing performance.
[0012] In some embodiments, the heat exchange assembly includes a plurality of heat exchange rows evenly spaced along the first direction, and each heat exchange row includes a plurality of heat exchange tubes. The above structure evenly arranges a plurality of heat exchange rows, thereby improving the balance of heat exchange of the gas inside the heat exchange cavity. Each heat exchange row is also provided with a plurality of heat exchange tubes, which increases the number of heat exchange tubes, increases the heat exchange area, and improves the heat exchange efficiency.
[0013] In some embodiments, each heat exchange tube includes two straight tube sections and a curved tube section. The two straight tube sections are evenly spaced along the second direction, the second direction intersects with the first direction, and the two ends of the curved tube section are respectively connected to the two straight tube sections. Among them, one of the two straight tube sections is connected to the liquid inlet, and the other of the two straight tube sections is connected to the liquid outlet. In the above structure, each heat exchange tube is a U-shaped structure, which can make full use of the space inside the heat exchange cavity to improve the heat exchange efficiency, and it has a certain structural stability, which helps to reduce the vibration and deformation of the pipeline during the heat exchange process, thereby ensuring the stability and durability of the heat exchange. In addition, the U-shaped pipeline facilitates the circulation of the heat exchange medium, improves the circulation performance of the heat exchange medium, and further promotes the transfer of heat.

The battery 2 includes a box body 5 and battery cells 7, and the battery cells 7 are accommodated in the box body 5. Among them, the box body 5 is used to provide an accommodation space 53 for the battery cells 7, and the box body 5 can adopt various structures.

The first part 51 and the second part 52 cover each other, and the first part 51 and the second part 52 together define a receiving space 53 for receiving the battery cells 7. Of course, the housing 5 formed by the first part 51 and the second part 52 can be of various shapes, such as a cylinder, a cuboid, etc.

[0045] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the battery cell 7 provided in an embodiment of the present application. The battery cell 7 refers to the smallest unit that makes up the battery 2. As Figure 3 shown, the battery cell 7 includes a housing 40, an electrode assembly 10, and other functional components. The housing 40 can include an end cap 30 and a casing 20. The end cap 30 refers to a component that covers the opening of the casing 20 to isolate the internal environment of the battery cell 7 from the external environment.
[0046] The electrode assembly 10 is a component in the battery cell 7 where an electrochemical reaction occurs. The housing 20 may contain one or more electrode assemblies 10. The electrode assembly 10 includes a positive electrode plate, a negative electrode plate, and a separator. The positive electrode plate includes a plate, a positive active material, and a binder. The negative electrode plate includes a plate, a negative active material, and a binder. The positive active material and the negative active material contain active ions. During the charging and discharging process of the battery cell 7, the active ions (such as lithium ions) are intercalated and deintercalated back and forth between the positive electrode plate and the negative electrode plate. The separator is disposed between the positive electrode plate and the negative electrode plate, which can prevent the short circuit between the positive and negative electrodes and allow the active ions to pass through at the same time.
[0047] In some embodiments, the battery cell 7 further includes an electrolyte, which plays a role in conducting ions between the positive and negative electrodes. There is no specific limitation on the type of the electrolyte in this application, and it can be selected according to requirements. The electrolyte can be liquid, gel-like, or solid. In some embodiments, the electrode assembly 10 is a wound structure. Optionally, the electrode assembly 10 is a stacked structure.
[0048] As the service life of the battery increases, many batteries gradually reach the retirement age, so it is necessary to recycle various materials in the battery to reduce its environmental pollution. Among them, the active powder on the battery electrode plate needs to be sintered. The gas discharged after sintering contains harmful substances such as tar, and it is necessary to carry out condensation recovery treatment on it to reduce the impact on the environment. In the commonly used condensation equipment, the sintering gas usually flows in a gas pipeline, and the gas pipeline is arranged in a cooling chamber, and there is a heat exchange medium flowing in the cooling chamber to exchange heat and cool the sintering gas. However, the gas pipeline in the above structure has a small diameter, the gas flow rate is fast, and the heat exchange efficiency is reduced. Moreover, the gas in the gas pipeline is easily blocked after condensation, the cleaning cycle is short, and the heat exchange stability is poor. Therefore, it is necessary to improve the above structure.
[0049] In view of the above problems, the embodiments of this application provide a gas heat exchange device. The design of the heat exchange chamber in the heat exchange device enables the gas to flow therein and exchange heat with the heat exchange component. Since the volume of the heat exchange cylinder is large, it provides sufficient flow space for the gas, enabling the gas to fully contact the heat exchange component during the flow process, thereby extending the time of gas heat exchange. Moreover, the heat exchange component is located in the heat exchange chamber, and the design of the heat exchange pipeline enables the heat exchange medium to flow therein and exchange heat with the gas to be heat exchanged. Therefore, the design of the gas heat exchange device fully considers the flow characteristics of the gas and the heat exchange requirements. By increasing the gas flow space, extending the heat exchange time, and optimizing the structure of the heat exchange component, this device can effectively improve the heat exchange efficiency, reduce the risk of blockage of the gas pipeline after the tar in the gas is condensed, and improve the heat exchange stability.
[0050] The following will describe in detail the gas heat exchange equipment and the battery material processing system provided by the embodiments of the present application. Please refer to Figures 4 to 6 , Figure 4 which is a schematic structural diagram of a gas heat exchange equipment according to an embodiment of the present application, Figure 5 and Figure 6 is Figure 5 the schematic structural diagram of the A-A cross-section in
[0051] As shown in the figure, the gas heat exchange equipment 6 includes a heat exchange cylinder 601 and a heat exchange component 602. The heat exchange cylinder 601 has a heat exchange cavity 603 for accommodating the gas to be heat-exchanged. A partition plate 623 is provided in the heat exchange cavity 603, and a gas through-hole 624 is provided on the partition plate 623. The heat exchange component 602 is arranged in the heat exchange cavity 603. The heat exchange component 602 has a heat exchange tube 620 through which the heat exchange medium flows, and the heat exchange component 602 is used to heat-exchange the gas to be heat-exchanged.
[0052] In the technical solution of the embodiment of the present application, the design of the heat exchange cavity 603 enables the gas to flow therein and exchange heat with the heat exchange component 602. Since the volume of the heat exchange cylinder 601 is relatively large, it provides sufficient flow space for the gas, enabling the gas to fully contact the heat exchange component 602 during the flow process, thereby prolonging the gas heat exchange time. A partition plate 623 is provided in the heat exchange cylinder 601, and a gas through-hole 624 is provided on the partition plate 623. The above structure can prolong the flow path of the gas in the heat exchange cavity 603 and improve the heat exchange efficiency. Moreover, the heat exchange component 602 is located in the heat exchange cavity 603, and the design of the heat exchange tube 620 enables the heat exchange medium to flow therein and exchange heat with the gas to be heat-exchanged. Therefore, the design of the gas heat exchange equipment 6 fully considers the flow characteristics and heat exchange requirements of the gas. By increasing the gas flow space, prolonging the heat exchange time, and optimizing the structure of the heat exchange component 602, this equipment can effectively improve the heat exchange efficiency, reduce the risk of blockage of the gas pipeline caused by tar condensation in the gas, and improve the stability of heat exchange.
[0053] In some embodiments of the present application, the volume occupied by the heat exchange component 602 in the heat exchange cavity 603 is less than or equal to half of the total volume of the heat exchange cavity 603. In the above structure, the volume of the heat exchange cavity 603 is increased, the risk of condensation and blockage of the heat exchange cavity 603 by the gas in the heat exchange cavity 603 is reduced, and the heat exchange efficiency and the stability of the commutation process are improved.
[0054] Such as Figure 5 and Figure 6As shown, in some embodiments of the present application, the heat exchange cylinder 601 includes a cylinder body 604 and a medium container 605. A gas outlet 607 and a gas inlet 606 communicating with the heat exchange chamber 603 are provided on the cylinder wall of the cylinder body 604. The medium container 605 is connected to one end of the cylinder body 604. The medium container 605 is provided with a medium outlet 609 and a medium inlet 608. The medium container 605 is used to accommodate the heat exchange medium. The medium inlet 608 communicates with the inlet of the heat exchange assembly 602, and the medium outlet 609 communicates with the outlet of the heat exchange assembly 602. In the above structure, the gas outlet 607 and the gas inlet 606 are provided on the cylinder wall of the cylinder body 604, which facilitates the entry of gas into the heat exchange chamber 603 for heat exchange. Moreover, the connection between the medium container 605 and the cylinder body 604 improves the convenience of the heat exchange medium entering the heat exchange assembly 602 and enhances the heat exchange efficiency.
[0055] In some embodiments of the present application, a condensation outlet 610 is provided at one end of the cylinder body 604 away from the medium container 605. In the above structure, the condensation outlet 610 is disposed opposite to the medium container 605, which enables reasonable arrangement of components, collects the condensed tar at the condensation outlet 610 by gravity, and facilitates the entry of the heat exchange medium in the medium container 605 into the cylinder body 604.
[0056] As Figure 7 and Figure 8 shown, in some embodiments of the present application, the medium container 605 includes a housing 611 and a partition 612. The housing 611 has a receiving cavity. The partition 612 is disposed inside the housing 611. The partition 612 divides the receiving cavity into a first cavity 613 and a second cavity 614. The medium inlet 608 communicates with the first cavity 613, and the medium outlet 609 communicates with the second cavity 614.
[0057] In the above structure, the partition 612 is provided in the housing 611, and the heat exchange medium is divided into two different flow paths in the receiving cavity. This division helps to avoid direct short-circuiting of the medium inside the container, ensuring that the medium can fully flow through the heat exchange tubes 620 of the heat exchange assembly 602, thereby improving the heat exchange efficiency. Moreover, the medium inlet 608 and the medium outlet 609 communicate with the first cavity 613 and the second cavity 614 respectively, which makes the connection structure between the medium container 605 and the heat exchange assembly 602 more concise and clear. This not only simplifies the equipment assembly and maintenance process but also helps to reduce the manufacturing cost of the equipment.
[0058] In some embodiments of the present application, the receiving shell 611 is further provided with a liquid outlet 616 and a liquid inlet 615. The liquid inlet 615 communicates with the first cavity 613 and is disposed opposite to the medium inlet 608, and the liquid outlet 616 communicates with the second cavity 614 and is disposed opposite to the medium outlet 609. In the above structure, the liquid inlet 615 is disposed opposite to the medium inlet 608, ensuring that the medium can directly enter the heat exchange assembly 602 from the first cavity 613; similarly, the liquid outlet 616 is disposed opposite to the medium outlet 609, enabling the medium to smoothly flow from the heat exchange assembly 602 to the second cavity 614. Moreover, the liquid inlet 615 and the liquid outlet 616 are directly connected to the internal cavity of the receiving shell 611, reducing the leakage risk of the medium during transmission.
[0059] In some embodiments of the present application, the gas heat exchange device 6 further includes a connection assembly. The connection assembly includes a first flange 617, a second flange 618, and a fastener. The first flange 617 is disposed on the outer periphery of the cylinder 604, the second flange 618 is disposed on the outer side of the receiving shell 611 facing away from the receiving cavity, and the fastener detachably connects the first flange 617 and the second flange 618. In the above structure, the detachable connection between the receiving shell 611 and the cylinder 604 is achieved by setting the connection assembly, improving the convenience of connection and the assembly efficiency between the receiving shell 611 and the cylinder 604 on the basis of ensuring the sealing performance of the shell 20.
[0060] In some embodiments of the present application, the heat exchange assembly 602 includes a plurality of heat exchange rows 619 uniformly spaced along the first direction X. Each heat exchange row 619 includes a plurality of heat exchange tubes 620. In the above structure, the uniform arrangement of a plurality of heat exchange rows 619 improves the balance of gas heat exchange inside the heat exchange cavity 603. Each heat exchange row 619 is further provided with a plurality of heat exchange tubes 620, increasing the number of heat exchange tubes 620 provided, enlarging the heat exchange area, and improving the heat exchange efficiency.
[0061] In some embodiments of the present application, each heat exchange tube 620 includes two straight tube segments 621 and a bent tube segment 622. The two straight tube segments 621 are uniformly spaced along the second direction Y, and the second direction Y intersects the first direction X. The two ends of the bent tube segment 622 are respectively connected to the two straight tube segments 621. Among them, one of the two straight tube segments 621 is connected to the liquid inlet 615, and the other of the two straight tube segments 621 is connected to the liquid outlet 616.
[0062] In the above structure, each heat exchange tube 620 is a U-shaped structure, which can make full use of the space inside the heat exchange cavity 603 to improve the heat exchange efficiency, and has a certain structural stability, helping to reduce the vibration and deformation of the pipeline during heat exchange, thus ensuring the stability and durability of heat exchange. Moreover, the U-shaped pipeline is convenient for the flow of the heat exchange medium, improving the flow performance of the heat exchange medium, and further promoting the transfer of heat.
[0063] Exemplarily, in any one of the heat exchange rows 619, a first pipe 625, a second pipe 626, a third pipe 627, a fourth pipe 628, and a fifth pipe 629 are sequentially arranged. Both ends of the first pipe 625 are respectively connected to a first inlet 630 and a first outlet 631 on the medium container 605. Both ends of the second pipe 626 are respectively connected to a second inlet 632 and a second outlet 633 on the medium container 605. Both ends of the third pipe 627 are respectively connected to a third inlet 634 and a third outlet 635 on the medium container 605. Both ends of the fourth pipe 628 are respectively connected to a fourth inlet 636 and a fourth outlet 637 on the medium container 605. Both ends of the fifth pipe 629 are respectively connected to a fifth inlet 638 and a fifth outlet 639 on the medium container 605.
[0064] In some embodiments of the present application, a partition plate 623 is provided in the heat exchange cylinder 601. One end of the partition plate 623 is connected to one side wall of the heat exchange cylinder 601, and a gas through hole 624 is formed between the other end of the partition plate 623 and the other side wall of the heat exchange cylinder 601. The above structure can extend the flow path of the gas in the heat exchange chamber 603 and improve the heat exchange efficiency.
[0065] In some embodiments of the present application, the number of the partition plates 623 is multiple, and the multiple partition plates 623 are evenly spaced along the third direction Z, and the third direction Z intersects the plane where the first direction X and the second direction Y are located. Among them, the gas through holes 624 on the multiple partition plates 623 are arranged staggeredly on both sides along the third direction Z. The above structure further extends the flow path of the gas in the heat exchange chamber 603 and improves the heat exchange efficiency.
[0066] In some optional embodiments, a plurality of through holes are provided on the partition plate 623, and the heat exchange tubes 620 pass through the through holes. The above structure facilitates the arrangement of the heat exchange tubes 620 by providing through holes, so that there is no interference between the structure of the partition plate 623 and the heat exchange tubes 620.
[0067] Embodiments of the present application also provide a battery material processing system, which includes the gas heat exchange device 6 in the above embodiments. Among them, the design of the heat exchange chamber 603 enables gas to flow therein and exchange heat with the heat exchange component 602. Since the heat exchange cylinder 601 has a relatively large volume, it provides sufficient flow space for the gas, enabling the gas to fully contact the heat exchange component 602 during the flow process, thereby prolonging the gas heat exchange time. Moreover, the heat exchange component 602 is located in the heat exchange chamber 603, and the design of the heat exchange tube 620 enables the heat exchange medium to flow therein and exchange heat with the gas to be heat-exchanged. Therefore, the design of the gas heat exchange device 6 fully considers the flow characteristics of the gas and the heat exchange requirements. By increasing the gas flow space, prolonging the heat exchange time, and optimizing the structure of the heat exchange component 602, this device can effectively improve the heat exchange efficiency, reduce the risk of blockage of the gas pipeline after tar condensation in the gas, and improve the stability of heat exchange.
