The electric furnace zinc powder settling and cooling device is designed to solve problems that may occur during the production of zinc powder, such as the stability and safety of the production process.

[0003] A search revealed an existing technology for an electric furnace zinc powder settling and cooling device (publication number: CN221312502U), comprising a settling tower one, a connecting pipe fixedly installed on the upper outer surface of the settling tower one, a settling tower two fixedly installed on the other outer surface of the connecting pipe, an air inlet pipe fixedly installed on the upper outer surface of the settling tower one, an air outlet pipe fixedly installed on the upper outer surface of the settling tower two, a cooling component fixedly installed on the upper outer surface of the settling tower one, and a collection box and a feeding pipe fixedly installed on the lower outer surfaces of both the settling tower one and the settling tower two, with the feeding pipe located on the lower outer surface of the collection box.

[0004] Existing technologies mainly use coils to transport coolant, and multiple baffles inside the settling tower to disperse and guide steam and achieve heat exchange. However, the contact surface area between the heat exchange coils and the settling tower and its interior is limited. Furthermore, although the multiple symmetrically distributed baffles can guide steam, they also increase the resistance during steam flow, affecting exhaust efficiency, and there is room for optimization.

[0005] To address this, we propose a multi-stage cooling assembly and an electric furnace zinc powder settling tower. Utility Model Content

[0006] The present invention mainly addresses the technical problems of limited steam heat exchange surface area and obstructed flow, and provides a multi-stage cooling component and an electric furnace zinc powder settling tower.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a multi-stage cooling assembly, comprising:

Several spacers are fixedly installed on the outside of the inner liner. The spacers form a curved flow channel on the outside of the inner liner. The baffles are fixedly installed on the inner wall of the inner liner and divide the chamber of the inner liner into a spiral settling channel.

[0010] In a preferred embodiment of this utility model, the inner liner is a square cylinder, and the inner liner cavity is a circular cavity.

[0011] In a preferred embodiment of this utility model, the spacer is a rectangular plate, the height of the spacer is less than the height of the inner liner, and two adjacent spacers are flush with the top and bottom of the inner liner, respectively.

[0012] An electric furnace zinc powder settling tower includes two parallel outer shells, each of which has a cavity containing all of the aforementioned multi-stage cooling components. An inner liner is fixedly installed inside the cavity of the outer shell, and a heat exchange cavity is formed between the inner liner and the inner wall of the outer shell.

[0016] Beneficial effects

[0017] This invention provides a multi-stage cooling assembly and an electric furnace zinc powder settling tower. It offers the following advantages:

[0018] 1. This multi-stage cooling component and electric furnace zinc powder settling tower, by injecting water into the outside of the inner tank and forming a serpentine flow channel on the outside of the inner tank through multiple spacers, creates a tortuous flow trajectory for the coolant as it passes through the flow channel, which increases the contact surface area between the coolant and the inner tank, thereby improving the cooling effect on the zinc powder vapor inside the inner tank. Secondly, the steam is guided by a spiral guide plate, which on the one hand ensures the smooth flow of steam along the radial direction of the inner tank and reduces turbulence, and on the other hand increases the contact surface area between the steam and the inner tank, promotes heat exchange between the steam and the coolant, further improves the cooling effect of the steam, and ensures the purity of the recovered zinc powder vapor in the electric furnace exhaust gas. The two parallel inner tanks can achieve multi-stage cooling of the steam to ensure sufficient cooling.

[0019] 2. This multi-stage cooling component and electric furnace zinc powder settling tower, by setting multiple spacers in the heat exchange chamber to form a serpentine flow channel, ensures the guidance of the coolant, extends the length of the cooling flow trajectory outside the inner tank to ensure sufficient heat exchange, and the coolant flow inside the two outer shells is individually controllable, which can achieve gradient cooling according to temperature. On the basis of achieving multi-stage effective cooling, the two outer shells cool the steam in stages and continuously to achieve recovery, with high recovery rate and purity.

[0020] 3. This multi-stage cooling component and electric furnace zinc powder settling tower can achieve multi-stage cooling by using multiple shells adjacent to each other. During installation, it is only necessary to connect two adjacent shells and the inner liner with a pipe, which realizes true modular cooling. This makes it more convenient for later maintenance and repair, and it is also convenient to increase or decrease the number of shells as needed. Attached Figure Description

[0027] A multi-stage cooling assembly and an electric furnace zinc powder settling tower, such as Figure 4 and Figure 5 As shown, it includes:

[0028] Inner liner 30, the inner liner 30 is hollow and forms a settling cavity;

[0029] A heat exchange structure is installed on the wall of the inner liner 30 for heat conduction. The heat exchange structure includes a spacer 15 and a baffle plate 20. Several spacers 15 are fixedly installed on the outside of the inner liner 30. The spacers 15 form a curved flow channel on the outside of the inner liner 30. The baffle plate 20 is fixedly installed on the inner wall of the inner liner 30. The baffle plate 20 divides the chamber of the inner liner 30 into a spiral settling channel. The inner liner 30 is a square cylinder as a whole. The chamber of the inner liner 30 is a circular cavity. The spacers 15 are rectangular plates. The height of the spacers 15 is less than the height of the inner liner 30. Two adjacent spacers 15 are flush with the top and bottom of the inner liner 30, respectively.

[0030] In this design, water is injected into the outside of the inner tank 30, and multiple spacers 15 create a serpentine flow channel on the outside of the inner tank 30. When the coolant passes through the flow channel, it forms a zigzag flow trajectory, which increases the contact surface area between the coolant and the inner tank 30, thereby improving the cooling effect on the zinc powder vapor inside the inner tank 30. Secondly, the steam is guided by a spiral guide plate 20, which ensures the smooth flow of steam along the radial direction of the inner tank 30 and reduces turbulence. On the other hand, it also increases the contact surface area between the steam and the inner tank 30, promotes heat exchange between the steam and the coolant, further improves the cooling effect of the steam, and ensures the purity of the recovered zinc powder vapor in the electric furnace exhaust gas. The two parallel inner tanks 30 can achieve multi-stage cooling of the steam to ensure sufficient cooling.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an electric furnace zinc powder settling tower includes two parallel outer shells 10. Each outer shell 10 has a cavity equipped with all the aforementioned multi-stage cooling components. An inner liner 30 is fixedly installed inside the cavity of the outer shell 10. A heat exchange cavity 14 is formed between the inner liner 30 and the inner wall of the outer shell 10. A cooling cavity 13 for settling is formed inside the inner liner 30. The side wall of the spacer 15 is fixedly connected to the inner wall of the outer shell 10. A first water pipe 16 and a second water pipe 17 are also fixedly installed on the side wall of the outer shell 10. Both the first water pipe 16 and the second water pipe 17 are connected to the heat exchange cavity 14. An air inlet pipe 11 is fixedly installed on the top of the outer shell 10. An exhaust pipe 12 for exhausting air is fixedly installed on the top of the other outer shell 10. A connecting pipe is fixedly installed on the side wall of the outer shell 10. The connecting pipe is connected to the cavities of the two inner liner 30 and is close to the bottom of the outer shell 10.

[0032] In practical use, exhaust gas is introduced through the intake pipe 11. The exhaust gas is guided from the cavity of the inner liner 30 through the guide plate 20 and then sent to another inner liner 30 through the pipe for further condensation before being discharged from the exhaust pipe 12. The cooled steam forms particles that settle at the bottom of the inner liner 30. Of course, the bottom of the inner liner 30 is provided with a discharge window, and a valve is provided at the window to control the opening and closing, so as to realize multi-stage cooling of steam. The first water pipe 16 and the second water pipe 17 are located on both sides of the same partition 15. The second water pipe 17 can be connected to a water source, and the first water pipe 16 can be connected to a return water tank to realize water circulation. By setting multiple partitions 15 in the heat exchange chamber 14, the heat exchange chamber 14 forms a serpentine flow channel, which ensures the guidance of coolant and extends the length of the cooling flow trajectory outside the inner liner 30 to ensure sufficient heat exchange. The flow of coolant inside the two outer shells 10 is individually controllable and can realize gradient cooling according to temperature. On the basis of realizing multi-stage effective cooling, the two outer shells 10 cool the steam in stages and continuously to achieve recovery, with high recovery rate and purity.

[0033] Multi-stage cooling can be achieved by using multiple outer shells 10 adjacent to each other. During installation, it is only necessary to connect two adjacent outer shells 10 and the inner liner 30 with a connecting pipe, which realizes true modular cooling. This makes it more convenient for later maintenance and repair, and also makes it easy to increase or decrease the number of outer shells 10 as needed.

[0034] The working principle of this utility model is as follows: Exhaust gas is introduced through the intake pipe 11. After being guided by the guide plate 20 from the cavity of the inner liner 30, the exhaust gas is sent to another inner liner 30 through the connecting pipe for further condensation and then discharged from the exhaust pipe 12. The cooled steam forms particles that settle at the bottom of the inner liner 30. Of course, the bottom of the inner liner 30 is provided with a discharge window, and a valve is provided at the window to control its opening and closing, so as to realize multi-stage cooling of steam. The first water pipe 16 and the second water pipe 17 are located on both sides of the same partition 15. The second water pipe 17 can be connected to a water source, and the first water pipe 16 can be connected to a return water tank to realize water circulation. Multiple spacers 15 create a serpentine flow channel on the outside of the inner liner 30. When the coolant passes through the flow channel, it forms a zigzag flow trajectory, which increases the contact surface area between the coolant and the inner liner 30, thereby improving the cooling effect on the zinc powder vapor inside the inner liner 30. Secondly, the spiral guide plate 20 guides the steam, ensuring smooth flow of the steam along the radial direction of the inner liner 30 and reducing turbulence. It also increases the contact surface area between the steam and the inner liner 30, promoting heat exchange between the steam and the coolant and ensuring the cooling effect on the steam.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
