Description

Technical Field

[0001] This utility model relates to the technical field of cooling spray equipment, and in particular to an improved cooling tower spray device. Background Technology

[0002] Temperature control in the zinc electrolysis cell is crucial for ensuring stable operation of the electrolysis system and is a significant factor affecting zinc sheet quality, production capacity, and cost. During zinc electrolysis, the electrolyte temperature continuously rises due to the electrothermal effect. Given the corrosive and crystallizing characteristics of zinc electrolyte, air-cooled towers with forced-air counter-current spraying and good droplet-catching capabilities are generally used to maintain a stable electrolysis temperature.

[0003] With the increase in electrolysis production capacity, the cooling capacity of traditional air-cooled towers with liquid distribution methods can no longer meet production requirements, especially during the peak summer production season. As ambient temperatures rise and system load increases, controlling the system tank temperature becomes increasingly difficult, limiting the capacity increase of the electrolysis system. The operating performance of an air-cooled tower is significantly affected by factors such as the gas-liquid ratio, cooling time (i.e., the residence time of the liquid in the cooling channel), heat exchange area during cooling (i.e., the specific surface area of ​​the liquid in the tower, i.e., the degree of liquid dispersion), gas-liquid distribution, and effective heat dissipation area. Under the same gas-liquid ratio and cooling time (i.e., same fan, same tower specifications, same liquid volume), the key factors affecting cooling efficiency are specific surface area and gas-liquid distribution.

[0004] In actual operation, existing air-cooled towers typically employ a large number of spray pipes (currently 40 main pipes and over 100 branch pipes) installed at the top of the tower, which pass through the drip trap layer. This easily leads to uneven liquid distribution, and the large number of nozzles and large spray droplets result in a small specific surface area of ​​the liquid inside the tower, uneven gas-liquid distribution, and a significant reduction in cooling efficiency. Therefore, this application proposes an improved cooling tower spray device that is easy to maintain and effectively improves cooling performance. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where a large number of nozzles leads to uneven gas-liquid distribution, which reduces the cooling effect. The invention proposes an improved cooling tower spray device that is easy to maintain and effectively enhances the cooling effect.

[0006] The technical solution of this utility model: An improved cooling tower spray device, comprising a zinc electrolysis cell, wherein a spray tower is fixedly installed on the top of the zinc electrolysis cell, and further comprising:

[0007] A spray pipe assembly, which has a U-shaped structure and is located on the outside of the spray tower, has several built-in spray pipes fixedly installed on two side plates of the spray tower that are far apart from each other. The built-in spray pipes are connected to the spray pipe assembly, and several volute nozzles are fixedly installed on the built-in spray pipes.

[0008] The enclosure structure is fixedly installed on the top of the spray tower and is composed of several heightening plates spliced ​​together.

[0009] Optionally, the spray pipe assembly includes an inlet tee pipe, which is disposed on one side of the spray tower. Two first bends are fixedly installed on the inlet tee pipe via a flange structure. A drain straight pipe is fixedly installed at the end of the first bend via a flange structure. One end of each built-in spray pipe is fixedly connected to a matching drain straight pipe via a flange structure.

[0010] Optionally, a second bend is fixedly installed on the straight drain pipe, and one end of each built-in nozzle is fixedly connected to the matching second bend via a flange structure.

[0011] Optionally, several insertion ports are cut into the two opposite side plates of the spray tower, and one end of the built-in spray pipe passes through the matching insertion port and is fixed to the outer side wall of the spray tower with bolts.

[0012] Optionally, a rubber sealing ring is movably fitted onto the outer wall of the built-in nozzle, and the rubber sealing ring is tightly clamped between the outer wall of the built-in nozzle and the inner wall of the insertion port.

[0013] Optionally, pipe support frames are fixedly installed on the liquid inlet tee, the first bend, and the liquid outlet straight pipe, and the bottom end of the pipe support frame is fixed to the top of the zinc electrolytic cell.

[0014] Optionally, a crossbeam bracket is fixedly installed on the inner wall of the height-increasing plate, a demister is fixedly installed on the top of the crossbeam bracket, and a fiberglass grating is fixedly installed on the top of the demister.

[0015] Optionally, both ends of the two drain pipes are fixedly fitted with caps via flange structures, and the caps are located on the drain pipe at the end away from the first bend.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects: the electrolyte is transported to the electrolytic tank below the spray tower by the spray components set on both sides of the spray tower. When the volute nozzle sprays the electrolyte, the spray force causes the slurry to fall in agglomerates, increasing the atomization area of ​​the liquid in the tower, allowing the air and electrolyte to exchange heat fully, effectively improving the cooling effect. The spray components are assembled and spliced ​​using a flange structure, which is convenient to disassemble and easy to clean the calcium and magnesium ion crystals inside the pipe, effectively improving the convenience of cleaning the inner wall of the pipe.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the present invention proposes an improved cooling tower spraying device, including a zinc electrolysis cell 1, a spraying tower 2 fixedly installed on the top of the zinc electrolysis cell 1, and several heightening plates 4 fixedly installed on the top of the spraying tower 2. Two adjacent heightening plates 4 are fixed by bolts. The several heightening plates 4 form a enclosure structure. The enclosure structure can increase the overall height of the spraying tower 2, increase the contact area between the atomized droplets and the air, and improve the demisting effect.

[0034] Furthermore, a U-shaped spray pipe assembly 3 is mounted on the top of the zinc electrolysis cell 1. The spray pipe assembly 3 is arranged around the outside of the spray tower 2. Several built-in spray pipes 8 are fixedly installed on the spray pipe assembly 3. One end of the built-in spray pipe 8 passes through the side plate of the spray tower 2 and extends into its interior. Several volute nozzles 9 with downward openings are fixedly installed on the built-in spray pipes 8. The electrolyte is transported into the spray tower 2 through the spray pipe assembly 3, and then sprayed out by the volute nozzles 9. The electrolyte is pressurized and transported through the spray pipe assembly 3 and sprayed out in a large flow rate through the volute nozzles 9. The spray force causes the slurry to clump together and fall, thereby increasing the atomization area of ​​the electrolyte inside the spray tower 2. This ensures that the air in the inner area of ​​the spray tower 2 can fully exchange heat with the atomized electrolyte (the current inlet and outlet temperature difference is 3-5℃, and the improved inlet and outlet temperature difference is 6-8℃), effectively improving the cooling effect on the electrolyte.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, to solve the problem of calcium and magnesium ion crystallization in the electrolyte causing pipe blockage, a multi-section pipe assembly 3 is constructed by splicing multiple pipe sections. The main body of the spray pipe assembly 3 consists of an inlet tee pipe 31, a first bend pipe 32, and a drain straight pipe 33. At the two ends of the inlet tee pipe 31 furthest from the inlet, the first bend pipe 32 is fixedly installed via flanges. At the end of the first bend pipe 32 furthest from the inlet tee pipe 31, the drain straight pipe 33 is fixedly installed via a flange. In actual installation, the number of drain straight pipes 33 can be increased or decreased according to the overall length of the spray tower 2 to meet the adaptability of the spray tower 2. Two adjacent drain straight pipes 33 are also connected and fixed using flanges to ensure the overall structural integrity of the spray pipe assembly 3. When calcium and magnesium ion crystallization occurs on the inner wall of the pipes involved in the spray pipe assembly 3, the spray pipe assembly 3 can be disassembled from the flange to facilitate cleaning of the inner walls of multiple independent short pipes and avoid internal blockage of the spray pipe assembly 3.

[0036] Furthermore, to facilitate the disassembly of the built-in spray pipe 8 and the drain straight pipe 33, several second bends 34 are fixedly installed on the outer wall of the drain straight pipe 33. One end of the built-in spray pipe 8 is fixedly connected to the matching second bends 34 through a flange structure. When it is necessary to disassemble the main body of the spray pipe assembly 3, the connection end between the built-in spray pipe 8 and the second bends 34 is first disassembled to facilitate the removal of the main body of the spray pipe assembly 3.

[0037] Secondly, to facilitate the removal of the built-in nozzle 8 from the spray tower 2, several insertion ports 21 are chiseled on the inner wall plate of the spray tower 2 near the drain straight pipe 33. One end of the built-in nozzle 8 passes through the matching insertion port 21 and is fixed to the outer wall of the spray tower 2 with bolts. The built-in nozzle 8 can be removed from the spray tower 2 by removing the bolts used for fixing, which facilitates the cleaning of calcium and magnesium ion crystals on the built-in nozzle 8 and the volute nozzle 9. The diameter of the built-in nozzle 8 is smaller than the inner diameter of the insertion port 21. When the built-in nozzle 8 is pulled out, the volute nozzle 9 is not blocked by the insertion port 21, which facilitates its disassembly and assembly.

[0038] like Figure 2 and Figure 5 As shown, in order to improve the stability of the spray pipe assembly 3 after installation, a pipe support frame 36 is fixedly installed on the top of the zinc electrolysis cell 1. The liquid inlet tee pipe 31, the first bend pipe 32 and the liquid outlet straight pipe 33 are all fixed by the sleeve on the top of the pipe support frame 36, ensuring that the spray pipe assembly 3 can be stably erected on the outside of the spray tower 2, effectively improving its stability after installation.

[0039] Furthermore, in order to improve the sealing performance of the assembly between the built-in nozzle 8 and the spray tower 2, a rubber sealing ring 81 is fitted on the outer wall of the built-in nozzle 8. When the built-in nozzle 8 is installed on the spray tower 2, the rubber sealing ring 81 is tightly clamped in the gap between the outer wall of the built-in nozzle 8 and the inner wall of the insertion port 21, effectively preventing the atomized electrolyte from being discharged outward from the gap.

[0040] Secondly, the ends of the two drain pipes 33 are fixed with caps 35 by bolts. The caps 35 are installed on the drain pipe 33 at the end away from the inlet tee pipe 31. The caps 35 can block the end of the spray pipe assembly 3 away from the inlet, ensuring that the electrolyte transported inside the spray pipe assembly 3 can enter the built-in spray pipe 8.

[0041] like Figures 1-3 As shown, in order to prevent the atomized electrolyte from being discharged to the outside of the spray tower 2, a crossbeam support 7 is fixedly installed on the inner wall of the riser plate 4. A demister 6 is fixedly installed on the top of the crossbeam support 7. A fiberglass grating 5 is provided on the top of the demister 6. The fiberglass grating 5 is fixedly installed on the inner wall of the riser plate 4. When the atomized electrolyte enters the interior of the demister 6, it can be allowed to gather into droplets and eventually fall into the zinc electrolysis cell 1, effectively preventing the electrolyte from being discharged from the inside of the spray tower 2.

[0042] In this embodiment, the electrolyte is first delivered to the inlet tee pipe 31 by a booster pump. The electrolyte is then diverted through the inlet tee pipe 31 to ensure that it can be discharged into the drain straight pipes 33 located on both sides of the spray tower 2. Because the electrolyte is pressurized during delivery, it can be sprayed out at high pressure from the volute nozzles 9 installed on the built-in spray pipe 8. The spray force causes the electrolyte slurry to clump together and fall, increasing the atomization area of ​​the electrolyte inside the spray tower 2, allowing it to fully exchange heat with the air in the inner area of ​​the spray tower 2, effectively improving the cooling effect. Since the electrolyte contains calcium and magnesium ions, the spray pipe assembly 3 further enhances the cooling effect. During the transportation process, ion crystals will appear inside the inlet tee 31, the first bend 32, the outlet straight pipe 33, the second bend 34, the built-in spray pipe 8, and the volute nozzle 9. To prevent the crystals from clogging the pipeline, regular cleaning is required. All of the above-mentioned pipeline structures are fixed with flange structures, which are convenient for disassembly and assembly. After the spray pipe assembly 3 is disassembled, it is convenient to clean the calcium and magnesium ion crystals inside the multiple short pipes. Moreover, the built-in spray pipe 8 is easy to remove from the spray tower 2, so it is convenient to clean the calcium and magnesium ion crystals on the built-in spray pipe 8 and the volute nozzle 9, which effectively improves the convenience of pipeline structure cleaning and maintenance.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
