AIR COOLING DEVICES HEAT-EXCHANGING TUBES EXTERNAL SURFACE CLEANING METHOD Russian patent published in 2018 - IPC B08B9/23 B08B9/32 B64F5/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to the main gas pipelines compressor stations air cooling devices heat-exchanging tubes cleaning. Air cooling devices heat-exchanging tubes external surface cleaning method includes feeding the cleaning agent in the vertical direction to the air-cooling device finned heat-exchanging tubes using containing pipes with spray nozzles cleaning section. Using installed vertically along the device heat exchange section long side additional cleaning section, performing the cleaner supply in the horizontal direction, perpendicular to the connecting tube plates. Through the additional cleaning section, the differentiated by the heating temperature air humidification degree along the rows of the air-cooling device finned heat exchange tubes regulation is also carried out, using installed on the additional cleaning section pipes controlled nozzles.

EFFECT: technical result consists in increase in the cleaning method efficiency by the cleaner supply in two directions, and setting the stream maximum possible pressure, maintaining the temperature balance of the gas in all rows of heat exchange tubes and thorough cleaning of the finned tubes outer surface.
