Technical Field

[0001] The utility model relates to the technical field of air-cooled island cleaning, in particular to an oil cleaning device for direct-cooling air-cooled island tubes. Background Technique

[0002] The working principle of the air-cooled island is to use the natural air to condense the process fluid, which is a large-scale industrial heat exchange device. In a thermal power plant, the air-cooled island usually consists of dozens of fans, and the air exchanges heat with the steam to achieve the cooling effect. This technology is mainly for water conservation and is widely used in power plants in water-scarce areas in the central and western regions of China.

[0003] When producing the air-cooled island, it is necessary to remove the oil stains on the surface of the air-cooled island tubes to avoid the oil stains on their surfaces affecting their thermal efficiency, thus posing a hidden danger to the safe operation of the system. Most of the existing methods for cleaning and removing the oil stains on the surface of the air-cooled island tubes are manual cleaning. Since the workpieces are flat tubes with long lengths and heavy weights, it is inconvenient for workers to clean, the labor intensity of workers is high, the degree of automation is low, and the surfaces of the workpieces are not easily cleaned. At the same time, the cleaning liquid is directly discharged after cleaning the workpieces and cannot be recycled, resulting in high cleaning costs. Summary of the Utility Model

[0023] As Figures 1 to 5 shown, the present utility model provides a cleaning and degreasing device for the direct-cooling air-cooled island pipes, including a liquid storage tank 1. A cleaning tank 2 is arranged on one side of the liquid storage tank 1. A guiding inclined plate 3 is fixedly connected to the bottom of the cleaning tank 2. A connecting pipe 4 is fixedly communicated with the bottom plate of the cleaning tank 2. The connecting pipe 4 is located above the lower end of the guiding inclined plate 3. The cleaning tank 2 is communicated with the liquid storage tank 1 through the connecting pipe 4. Channel openings 5 for the air-cooled island pipes to enter and exit are formed on the opposite two side walls of the cleaning tank 2. A spray cleaning mechanism is arranged in the cleaning tank 2 and is correspondingly arranged with the channel openings 5. A liquid supply assembly is arranged in the liquid storage tank 1. The end of the liquid supply assembly is communicated with the spray cleaning mechanism. A filter 6 for filtering the cleaning liquid is arranged on the liquid supply assembly.

[0024] As a further optimized solution, the liquid supply assembly includes a water pump 7 arranged in the liquid storage tank 1. The water outlet end of the water pump 7 is fixedly communicated with a liquid supply pipe 8. The end of the liquid supply pipe 8 is communicated with the spray cleaning mechanism. The filter 6 is installed on the liquid supply pipe 8.

[0025] As a further optimized solution, a first filter screen 9 is installed at the water inlet end of the water pump 7.

[0026] For a further optimized solution, the spray cleaning mechanism includes an annular pipe 10 fixedly installed on the inner wall of the cleaning tank 2. The annular pipe 10 is arranged vertically. Spray components are installed at both the upper and lower ends inside the annular pipe 10. The spray components are communicated with the annular pipe 10, and the channel opening 5 is arranged between the two spray components.

[0027] For a further optimized solution, horizontal spray nozzles 11 are installed at both the left and right ends inside the annular pipe 10. The horizontal spray nozzles 11 are communicated with the annular pipe 10.

[0028] For a further optimized solution, the spray component includes a swing motor 12 fixedly connected to the annular pipe 10. The output end of the swing motor 12 is fixedly connected with a mounting plate 13. A vertical spray nozzle 14 is fixedly connected to the mounting plate 13. The water inlet end of the vertical spray nozzle 14 is communicated with the annular pipe 10 through a hose 15.

[0029] For a further optimized solution, a roller 16 is rotatably connected to the bottom of the channel opening 5.

[0030] For a further optimized solution, the filter 6 includes a housing 61. The liquid supply pipe 8 at the liquid inlet end of the housing 61 is fixedly communicated with the housing 61.

[0031] When the direct cooling and air cooling island tube cleaning and oil removal device provided by the present utility model is in use, the air cooling island tube to be cleaned enters the cleaning tank 2 through the channel opening 5 on the cleaning tank 2. While the air cooling island tube is being sent into the cleaning tank 2, the water pump 7 and the swing motor 12 are started. The cleaning liquid in the liquid storage tank 1 is pumped into the annular pipe 10 through the water pump 7. In this process, the cleaning liquid will be filtered through the first filter screen 9 and the second filter screen 62 in sequence. After the cleaning liquid enters the annular pipe 10, it is sprayed out through the horizontal spray nozzles 11 and the vertical spray nozzles 14 to clean the air cooling island tube. Through the setting of the swing motor 12, the vertical spray nozzle 14 can swing reciprocally along the advancing direction of the air cooling island tube. During the swinging process of the vertical spray nozzle 14 and the advancing of the air cooling island tube, the contact angle between the water column sprayed out by the vertical spray nozzle 14 and the air cooling island tube can be changed, so as to improve the cleaning effect on the air cooling island tube. Moreover, by limiting the swinging direction of the vertical spray nozzle 14, the contact time between the water column and the air cooling island tube can be ensured, which also helps to improve the cleaning effect on the air cooling island tube. The cleaned cleaning liquid is gathered by the guiding inclined plate 3 and enters the liquid storage tank 1 through the connecting pipe 4 for repeated use.
