DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0029] Please refer to Figures 1-6 The present application provides a vertical condenser system for recycling lithium batteries, which comprises a frame 1, and a vertical condenser tower body 2 is installed on the frame 1. In the embodiment, the frame comprises a support base, and the height of the support base is designed in accordance with ergonomics to prevent personnel from being scalded when approaching. A partition 3 is installed in the vertical condenser tower body 2, and the vertical condenser tower body is divided into an air inlet area 4 and an air outlet area 5 by the partition. The air inlet area and the air outlet area form a U-shaped air flow passage, and a gas inlet 6 and a gas outlet 7 are installed on the vertical condenser tower body and communicate with the air inlet area and the air outlet area, respectively. A heat exchange module for exchanging heat with high-temperature flue gas in the air flow passage is installed on the vertical condenser tower body. The heat exchange module comprises a heat exchange cavity 13 which is sleeved outside the air flow passage. Cooling liquid is installed in the heat exchange cavity. The cooling liquid in the heat exchange cavity exchanges heat with the high-temperature flue gas in the air flow passage. A condensate water collection system is installed in the vertical condenser tower body corresponding to the bottom position of the U-shaped air flow passage. The condensate water collection system comprises a conical collection cavity 14 installed at the bottom of the vertical condenser tower body, and a liquid discharge valve 15 is installed at the bottom of the conical collection cavity. A liquid level meter 16 is installed on the vertical condenser tower body to monitor the liquid level in the conical collection cavity. The condensate water can be conveniently discharged, and the accumulation of the condensate water and the possible damage to the system are avoided. At the same time, the liquid level meter installed on the vertical condenser tower body can monitor the liquid level in the conical collection cavity in real time, providing an intuitive monitoring means for the operator and ensuring the safe operation of the system. The system adopts a vertical design, can be installed vertically, reduces the occupied area, and facilitates the natural circulation of the cooling liquid.

[0030] The gas inlet 6 and the gas outlet 7 are arranged at the top of the vertical condensing tower body, and a plurality of vertical condensing tower bodies are arranged in series. First, this design enables the high-temperature flue gas to flow through the condensing tower body from top to bottom, fully utilizes the effect of gravity, helps the heat in the flue gas to be more effectively transferred to the cooling liquid, and thus improves the heat exchange efficiency. Second, the multi-stage series processing mode can flexibly adjust the number of condensing tower bodies according to actual processing requirements, so as to ensure that the flue gas cooling effect reaches the best. This flexibility not only improves the adaptability of the system, but also enables the system to maintain efficient and stable operation under different working conditions.

[0031] The vertical condensing tower body is of a split structure, and includes an upper tower body 8 and a lower tower body 9 which are connected to each other through flanges. First, the split structure makes the installation, disassembly and maintenance of the vertical condensing tower body more convenient, and reduces the maintenance cost and time. When it is necessary to clean or replace the internal components, the flanges can be easily disassembled without disassembling the entire tower body.

[0032] As a preferred embodiment, the upper tower body is provided with an upper support plate 10 and a lower support plate 11, and a plurality of multi-pipe type air ducts 12 are arranged between the upper support plate and the lower support plate. A partition plate is arranged above the upper support plate to divide the chamber at the top of the upper tower body into a gas inlet area and a gas outlet area. The flue gas is transported from top to bottom through the air ducts in the gas inlet area, and then transported from bottom to top through the air ducts in the gas outlet area and discharged from the gas outlet area. A condensate water collecting system is arranged in the lower tower body. The design of the upper support plate, the lower support plate and the plurality of multi-pipe type air ducts arranged in the upper tower body further optimizes the flow path of the flue gas. The flue gas is transported from top to bottom through the air ducts in the gas inlet area, and then transported from bottom to top through the air ducts in the gas outlet area. This U-shaped flow mode not only prolongs the residence time of the flue gas in the tower body, but also increases the contact area between the flue gas and the cooling liquid, thereby improving the heat exchange efficiency. In addition, the partition plate is arranged above the upper support plate to divide the chamber at the top of the upper tower body into a gas inlet area and a gas outlet area. This design makes the flow of the flue gas more orderly, avoids the turbulence and short circuit phenomenon of the flue gas in the tower body, and further improves the stability and efficiency of the heat exchange. Finally, the condensate water collecting system is arranged in the lower tower body, which not only avoids the corrosion and damage of the condensate water to the upper components of the tower body, but also facilitates the collection and discharge of the condensate water. This design enables the condensate water to flow smoothly into the conical collecting cavity and be discharged in time through the drain valve, thereby ensuring the continuous and stable operation of the system.

[0033] As a preferred embodiment, the heat exchange cavity in the upper tower body is surrounded by the inner wall of the upper tower body, the lower support plate and the upper support plate, and the heat exchange cavity in the lower tower body is installed on the outside of the lower tower body to prevent the outside of the lower tower body from being scalded by contact. The heat exchange cavity in the upper tower body and the heat exchange cavity in the lower tower body are connected through the U-shaped connecting pipe 19. This design not only effectively protects the outside of the lower tower body from being scalded by high temperature, but also ensures the integrity and sealing of the heat exchange cavity, and improves the efficiency of heat exchange. At the same time, the heat exchange cavities in the upper tower body and the lower tower body are connected through the U-shaped connecting pipe, so that the cooling liquid can flow smoothly between the two heat exchange cavities, further enhancing the uniformity and stability of heat exchange.

[0034] As a preferred embodiment, the upper tower body is provided with a liquid discharge valve one 17 connected with the heat exchange cavity in the upper tower body, and the lower tower body is provided with a liquid discharge valve two 18 connected with the heat exchange cavity in the lower tower body. This design provides great convenience for the discharge and replacement of cooling liquid. The operator can discharge and replace the cooling liquid in the heat exchange cavity at any time according to actual needs, ensuring the continuous and efficient operation of the system.

[0035] As a preferred embodiment, the cooling liquid inlet in the heat exchange cavity is installed at the bottom position, and the cooling liquid outlet in the heat exchange cavity is installed at the top position, forming a cooling liquid flow path of lower inlet and upper outlet, that is, the cooling water enters from the bottom of the condenser, the internal water level gradually rises, so that the cooling liquid fully contacts with the flue gas pipeline and greatly prolongs the basic time, thereby improving the heat exchange efficiency. The high-temperature flue gas is transported from the flue gas pipeline (heat transfer pipe bundle), which can ensure uniform distribution of flue gas to effectively participate in the heat exchange process.

[0036] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
