Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically to a cooling tower for producing acetylene using the calcium carbide method. Background Technology

[0002] Currently, cooling towers used in the calcium carbide-based acetylene production process accumulate significant dirt and grime on their inner walls due to prolonged use. This necessitates manual cleaning, which is labor-intensive and requires stopping the process, making cleaning the inner walls extremely inconvenient. Furthermore, the excessive dust buildup in existing cooling towers clogs the filters, hindering operation and requiring regular manual cleaning. Forgetting to clean them will disrupt normal operation. Additionally, the inlet pipes of most existing calcium carbide-based acetylene production cooling towers use straight pipe connections, resulting in poor cooling efficiency. To address these issues, a cooling tower for calcium carbide-based acetylene production that automatically cleans its inner walls, periodically cleans its filters, and provides superior cooling performance is needed. Summary of the Invention

[0033] For an example, please refer to... Figure 1-8 The present invention provides a technical solution:

[0034] A cooling tower for acetylene production via the calcium carbide method includes a connecting base 1, a water storage tank 2 connected to one end of the connecting base 1, a cooling tower body 3 connected to the end of the water storage tank 2 via a connecting column, a filter screen 4 installed at the air inlet between the water storage tank 2 and the cooling tower body 3, a water pump 5 installed on the side wall of the cooling tower body 3, a fixed connecting plate 6 connected to the inner cavity of the cooling tower body 3, and a spray cleaning structure 7 connected to the inner cavity of the cooling tower body 3 and located on the fixed connecting plate 6. A spiral gas cooling pipe 8 is connected above the spray cleaning structure 7. A steam screen plate 9 is connected in the inner cavity of the cooling tower body 3 and above the spiral gas cooling pipe 8. A drive fan 10 is connected in the inner cavity of the cooling tower body 3 and above the steam screen plate 9. A cleaning water inlet structure 11 is provided on the side wall of the water storage tank 2 and the cooling tower body 3, corresponding to the filter screen 4. A buoyancy switch 12 is connected on the side wall of the inner cavity of the water storage tank 2. An intelligent controller 13 is provided on the side wall of the cooling tower body 3.

[0035] In this embodiment, reference Figure 1 , Figure 2 , Figure 4 and Figure 5The spray cleaning structure 7 includes a fixed housing 701. Multiple sets of electric telescopic rods 702 are connected to the end face of the fixed housing 701. The electric telescopic rods 702 are connected to the bottom of the fixed connecting plate 6. A drive motor 703 is connected inside the fixed housing 701. The drive motor 703 is started when it is electrically connected to the intelligent controller 13 via wires, causing its drive end to rotate. A drive worm gear 704 is connected to the drive end of the drive motor 703 via a coupling, and the drive worm gear 704 is connected to the inside of the fixed housing 701 via a bearing seat. The drive worm 704 is rotated when connected to the bearing housing via a rotatable connection. A drive worm wheel 705 is meshed with the drive worm 704, causing the drive worm wheel 705 to rotate. A main water spray pipe 706 is connected to the center of the drive worm wheel 705. One end of the main water spray pipe 706, located within the cavity of the fixed housing 701, is connected to a water pump 707. The other end of the main water spray pipe 706 is connected to multiple sets of water spray branch pipes 708. Multiple sets of cleaning nozzles 709 are symmetrically connected to the side walls of the water spray branch pipes 708. The main water spray pipe 706 is connected to the fixed housing 701 via a bearing housing. Inside the cooling tower body 3, the water spray main pipe 706 is rotatably connected to the bearing housing, causing the water spray main pipe 706 to rotate. This, in turn, causes the water spray branch pipe 708 on the water spray main pipe 706 to rotate. Simultaneously, the water suction pump 707 is started when it is electrically connected to the intelligent controller 13 via a wire. This causes the cleaning nozzle 709 to spray water into the inner cavity of the cooling tower body 3. The drive fan 10 is also started when it is electrically connected to the intelligent controller 13 via a wire. This causes the atomized water in the inner cavity of the cooling tower body 3 to evaporate upwards. The heat of the gas in the spiral gas cooling pipe 8 is removed, thereby achieving a cooling effect. After a long period of operation, a large amount of dirt will appear on the side wall of the inner cavity of the cooling tower body 3. At this time, the electric telescopic rod 702 is started under the condition that the electric telescopic rod 702 is connected to the intelligent controller 13 through the wire and the connection method is electrical connection. The fixed connection plate 6 is provided with through holes corresponding to the water spray main pipe 706. Under the condition that the water spray main pipe 706 and the through hole are connected in a sliding connection, the spray cleaning structure 7 is moved up and down, thereby cleaning the side wall of the inner cavity of the cooling tower body 3 is completed while the water spray branch pipe 708 rotates.

[0036] In this embodiment, reference Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8The cleaning water inlet structure 11 includes two sets of fixed connecting frames 101, which are respectively connected to the side walls of the water storage tank 2 and the cooling tower body 3. A ring-shaped guide rail 102 is connected to the fixed connecting frame 101 via a connecting block. A drive wheel 103 is connected to the ring-shaped guide rail 102, and a servo motor 104 is connected to the center of the drive wheel 103. The buoyancy switch 12 is electrically connected to the intelligent controller 13 via a wire, and the water inlet pump 5 is electrically connected to the buoyancy switch 12 via a wire. With the inlet of the cleaning water pipe 108 connected to the outlet of the water inlet pump 5, the cleaning nozzle 109 on the cleaning water pipe 108 sprays water onto the filter screen 4, thereby filling the water storage tank 2. Simultaneously, the servo motor 104 is electrically connected to the intelligent controller 13 via a wire. The servo motor 104 is driven to rotate, thereby driving the drive wheel 103 and the driven wheel 105 to rotate. The driven wheel 105 is rotatably connected to the end face of the servo motor 104 and located on one side of the drive wheel 103 via a rotating shaft. A cleaning plate 106 is connected to the side wall of the servo motor 104 via a connecting seat. Several sets of cleaning brushes 107 are connected to the side wall of the cleaning plate 106 and located on one side of the filter screen 4. A cleaning water pipe 108 is connected to the other side wall of the servo motor 104 via a connecting seat. Several sets of cleaning nozzles 109 are connected to the side wall of the cleaning water pipe 108 and located on one side of the filter screen 4. Under these conditions, the servo motor 104 moves on the annular guide rail 102, thereby causing the cleaning plate 106 and the cleaning water pipe 108 on the servo motor 104 to rotate along the filter screen 4, thereby causing the cleaning brushes 107 and the cleaning nozzles 109 on the cleaning plate 106 and the cleaning water pipe 108 to clean the filter screen 4.

[0037] In this embodiment, reference Figure 1 , Figure 2 and Figure 3 By connecting a spiral gas cooling pipe 8 inside the cooling tower body 3 and above the spray cleaning structure 7, and by making the spiral gas cooling pipe 8 with copper material and a spiral structure design, the time that the gas spends in the spiral gas cooling pipe 8 is increased, thereby improving the cooling effect.

[0038] The workflow of this invention is as follows: When using a cooling tower for acetylene production via the calcium carbide method, firstly, the device is powered on to put it into operation. Then, the pipe for the generated gas is connected to the spiral gas cooling pipe 8. Next, the drive motor 703 is started under the condition that it is electrically connected to the intelligent controller 13 via wires, causing the drive end of the drive motor 703 to rotate. The drive worm 704 is connected to the inner cavity of the fixed housing 701 via a bearing seat, and the drive worm 704 is rotated under the condition that the connection between the drive worm 704 and the bearing seat is rotatable. The drive worm wheel 705 is meshed with the drive worm 704, causing the drive worm wheel 705 to rotate. The water spray main pipe 70... 6. The water spray main 706 is connected to the inner cavity of the fixed housing 701 via a bearing seat. With the water spray main 706 rotated in a rotatable connection to the bearing seat, the water spray branch pipe 708 on the water spray main 706 rotates. Simultaneously, the water suction pump 707 is started, connected electrically to the intelligent controller 13 via a wire. This causes the cleaning nozzle 709 to spray water into the inner cavity of the cooling tower body 3. The drive fan 10 is also started, connected electrically to the intelligent controller 13 via a wire. This causes the atomized water in the inner cavity of the cooling tower body 3 to evaporate upwards, thus carrying away the heat from the gas in the spiral gas cooling pipe 8. To achieve a cooling effect, after prolonged operation, a large amount of dirt will appear on the side wall of the inner cavity of the cooling tower body 3. At this time, the electric telescopic rod 702 is activated when it is connected to the intelligent controller 13 via a wire. The electric telescopic rod 702 is fixed and has through holes corresponding to the water spray main pipe 706. The water spray main pipe 706 is slidably connected to the through holes, thereby driving the spray cleaning structure 7 to move up and down. This cleans the side wall of the inner cavity of the cooling tower body 3 while the water spray branch pipe 708 rotates. After the water level in the water tank 2 drops, the buoyancy switch 12 is connected to the intelligent controller 13 via a wire, and the water pump 5 is connected to the intelligent controller 13 via a wire. When the water pump 5 is started under the condition of being connected to the buoyancy switch 12 and the connection method is electrical, and the water inlet of the cleaning water pipe 108 is connected to the outlet of the water pump 5, the cleaning nozzle 109 on the cleaning water pipe 108 sprays water jets onto the filter screen 4, thereby filling the water storage tank 2. At the same time as filling the water, the servo motor 104 is driven by the intelligent controller 13 through the wire and the connection method is electrical, so that the drive end of the servo motor 104 rotates, thereby driving the drive wheel 103 and the driven wheel 105 to rotate, so that the servo motor 104 moves on the annular guide rail 102, thereby causing the cleaning plate 106 on the servo motor 104 and the cleaning water pipe 108 to rotate along the filter screen 4.This allows the cleaning plate 106 and the cleaning brushes 107 and cleaning nozzles 109 on the cleaning water pipe 108 to clean the filter screen 4. A spiral gas cooling pipe 8, made of copper and designed with a spiral structure, is connected inside the cooling tower body 3 and above the spray cleaning structure 7. This increases the time the gas spends in the spiral gas cooling pipe 8, thereby improving the cooling effect.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
