Equipment for cleaning and restoring air dryers and smoke-flu heaters

Abstract

The invention relates to a device (100) for cleaning or restoring air-flue heat exchangers and flue-flue heat exchangers, comprising a stainless steel pipe (106) with pressurized water flow; one or more inductors (104) mounted on the stainless steel pipe (106) at basic position near the water outlet (130), wherein the inductors (104) are powered by an induced current and induce a water flow; One or more ultrasonic transducers (102) with piezoelectric ceramics, in which the ultrasonic transducer (102) is fitted into a stainless steel tube (106) at an acute angle, generating ultrasonic waves in the water being drawn in, thereby forming structured water at the water outlet (130); and the automatic numbering system is connected to the induction power source and is configured with a predetermined number to direct the water outlet (130) of the device (100) to flow across the in-situ heat exchange elements of the air dryer and flue-smoke heater to clean or restore the performance of the air dryer and flue-smoke heater.
