METHOD OF CLEANING EXTERNAL HEAT EXCHANGE SURFACE OF AIR COOLER Russian patent published in 2025 - IPC B08B9/00 

FIELD: cleaning.

SUBSTANCE: invention relates to the technology of cleaning external surfaces of air coolers used at power plants, hydrocarbon production and transportation enterprises, chemical and metallurgical industries and other facilities. Method of cleaning the external heat exchange surface of the air cooling apparatus, characterized by the fact that the external heat exchange surface is cleaned with water sprayed onto the surface by nozzles of a washing device which moves in a plane parallel to the side frames of the heat exchange apparatus; speed of movement of the washing device and the number of passes over the cleaned surface are set so that after the next cleaning cycle the thermal efficiency for the air cooling apparatus without condensation of the cooled heat carrier and the relative value of the available temperature difference for the air cooler with condensation of the cooled heat carrier, calculated from the measured: inlet temperature of the cooled heat carrier, outlet temperature of the cooled heat carrier, inlet pressure of the cooled heat carrier, inlet temperature of the cooling air correspond to the target values of said parameters.

EFFECT: achievement of target values of thermal efficiency and relative value of available temperature difference.
