Description

Technical Field

[0002] Air-cooling towers are widely used in industrial production. The safety and economy of their operation depend to a large extent on the cleanliness of the equipment. As the use time increases, a large amount of dust, catkins and other debris will accumulate inside the air-cooling tower. These pollutants will adhere to the surface of components such as fin tubes, seriously affecting the heat exchange effect of the air-cooling tower. The existing air-cooling tower cleaning devices generally use high-pressure water spraying to flush and clean the fins of the air-cooling tower. The existing air-cooling tower cleaning devices do not flush thoroughly, have high labor costs, cannot flush at high places, require manual dragging of pipelines, and waste a lot of desalted water. When above the transformer, a large amount of desalted water drips, which may cause non-stop accidents and make it difficult to ensure the cleaning effect of the air-cooling tower fins. In addition, it is very easy to get stuck during use, the walking distance is not fixed, and it is easy to get off the track and roll over, which greatly affects the stable operation of the air-cooling tower unit and is not conducive to better use.

The compressor pipeline is connected to the compressor room from behind the original air outlet pipeline and then to the equipment. The pipeline after the equipment is then connected to the original pipeline.

[0037] Each side of the air-cooling island is equipped with a local manual operation unit for local operation. Each unit is equipped with a PLC control and communication cabinet (touch screen) to achieve local / remote control switching. At the same time, a host computer system is installed in the control room, using optical fiber remote communication. From the control room, functions such as starting the water pump, running any ladder rack, program-running flushing, and switching between air and water flushing can be realized. Water pump pressure, gas pressure, and electric door signal are displayed.

[0038] The control system can realize local / remote control switching. Each single side of the air-cooling island is equipped with a local manual operation unit, which can realize local operation.

[0040] During use, if remote control is adopted, the operator selects the single side of the air-cooling tower that needs to be cleaned through the upper computer system in the control room, sets the cleaning mode, cleaning time and other parameters, and then starts the water pump and the air compressor booster pump to make the water and gas reach a suitable pressure, and then controls the first reduction motor 407 of the horizontal sliding device 4 to start, the first reduction motor 407 drives the first transmission wheel 408 to rotate, the first transmission wheel 408 drives the second transmission wheel 410 to rotate through the chain 413, the second transmission wheel 410 drives the third transmission wheel 411 to rotate through the chain 413, and the first transmission wheel 408 drives the second transmission wheel 410 to rotate through the chain 413.

When the sliding frame 12 reaches the limit position, the second reduction motor 801 is controlled to stop to ensure the safe operation of the cleaning device. After cleaning is completed, the water pump and the air compressor booster pump are stopped first, and then the horizontal sliding device 4 and the lifting device 8 are controlled to move the air-water combined cleaning device 7 back to the initial position.

The impact force of the gas can more effectively remove dirt between the heat dissipation fins, thereby achieving a better cleaning effect on the heat dissipation fins. By setting a water flushing nozzle bracket 707 in conjunction with a high-pressure nozzle 711 to spray out, dust, catkins and other debris attached to the surface of the air-cooling tower fins can be more thoroughly cleaned, thereby improving the heat exchange efficiency of the air-cooling tower and ensuring the stable operation of the air-cooling tower unit.
