Description

TECHNICAL FIELD

[0001] The utility model relates to air cooling tower maintenance technical field, concretely is a kind of air cooling tower internal cleaning device. BACKGROUND

[0002] Cooling tower is a kind of equipment using water and air contact, through evaporation to dissipate the waste heat generated in industry or refrigeration air conditioning. Basic principle is: dry (low enthalpy) air is drawn by fan, and enters the cooling tower from the air inlet net; high-temperature water molecules with high saturated vapor partial pressure flow to the air flow with low pressure, and wet hot (high enthalpy) water is sprayed into the tower from the water spraying system. When water droplets and air contact, on the one hand, due to the direct heat transfer between air and water, on the other hand, due to the pressure difference between water vapor surface and air, evaporation occurs under the action of pressure, and the latent heat of evaporation is taken away, that is, the heat in the water is taken away, so as to achieve the purpose of cooling.

[0003] The existing can refer to the announcement number: CN220187540U of Chinese utility model patent, which discloses an indirect air cooling tower internal cleaning device, which comprises a transmission assembly, a rotating scraping assembly and a cleaning assembly. The rotating scraping assembly comprises an air cooling tower body, a first rotating ring is slidably connected to the top end of the air cooling tower body, a first cross is fixedly connected to the inner wall of the first rotating ring, a transmission shaft is fixedly connected to the inner wall of the first cross, a second cross is fixedly connected to the bottom end of the air cooling tower body, and a second rotating ring is slidably connected to the top end of the air cooling tower body. In the utility model, the impurities on the inner wall of the air cooling tower body are scraped off by the rotating scraping assembly, and then the water is sprayed out through the water spraying port on the water spraying pipe to spray and clean the place where the impurities are scraped off, so as to avoid the cleaning dead angle and effectively expand the cleaning coverage.

[0004] Because the inside of large air cooling tower is in arc line structure, the existing cleaning device cannot limit the distance between the water flow discharge position and the air cooling tower inner wall when in use, resulting in that the impact force of water flow contacting with the air cooling tower inner wall is small, which affects the flushing effect. Moreover, due to the influence of the height of the air cooling tower, the water conveying pipe is long, and when the water flow is discharged from the water pipe, the water generates a reaction on the water pipe. When cleaning the large air cooling tower, the device needs to circle around the air cooling tower inner wall, resulting in that the bottom of the water pipe shakes, which has certain safety hidden danger, and also affects the overall structural strength of the water pipe, shortens the service life of the water pipe. At the same time, the position of the liquid pump changes constantly in the process of rotating the device, so that the power supply and water supply of the liquid pump are very inconvenient.
