Hydrodynamic method CLEAN tube heat exchanger cooling system POWER PLANTS

摘要

Hydrodynamic method for cleaning tubular heat exchangers of cooling systems of power plants by vibrodynamic impact on interior surfaces to be cleaned solid material loosely arranged in the cavity of each tube, characterized in that through the heat exchange tubes (water sections or water radiators) mounted on the supporting-movable frame, through tube circulating the mixture consisting of washing the acid solution and the abrasive impurities in the form of quartz sand in a range of 15-20% of the total volume of the mixture and e ohms by an electromechanical vibrator in a direction perpendicular to the axes of the tubes provide a vibration supporting-movable frame with a frequency less than 100 Hz and with an amplitude oscillation at 1.2-1.4 times the diameter or width of the cleaned tubes.
