DEVICE FOR PREVENTION OF FORMATION OF DEPOSITS IN HEAT EXCHANGER (VERSIONS) Russian patent published in 2013 - IPC F28G7/00 

FIELD: heating.

SUBSTANCE: effective operation of proposed device on heat exchangers of different purpose requires dissimilar assemblies of action on heat carrier. Device for prevention of formation of deposits in hot water supply heat exchanger additionally includes control device receiving signals from temperature sensor installed at outlet of the second stage of heat exchanger; assembly of action on heat carrier is installed on outlet pipeline of the first stage of heat exchanger; with that, its housing with solenoid winding is installed vertically, and its bar from ferromagnetic material is made in the form of hollow stock and installed with possibility of being moved till full opening or covering of hole of outlet pipeline; with that, solenoid winding is connected to control device, and assembly of supply of pulse mechanical vibrations, which interacts with housing of heat exchanger, is made in the form of piezoelectric element operating intermittently on proper resonant frequency of heat exchanger, which is connected to control device. Device for prevention of formation of deposits in heat exchanger of heating system additionally includes the control device receiving signals from temperature sensor installed at outlet of the second stage of heat exchanger, assembly of action on heat carrier consists of ball valve installed coaxially on outlet pipeline of the first stage of heat exchanger; with that, on ball axis there rigidly installed on outer side is gear wheel of drive worm-and-worm pair, which is equipped with sensor of worm-and-worm pair motor shutdown; besides, motor is connected to control device, and assembly of supply of pulse mechanical vibrations, which interacts with housing of heat exchanger, is made in the form of piezoelectric element operating intermittently on proper resonant frequency of heat exchanger, which is connected to control device.

EFFECT: improving operating efficiency of device, due to supply of heat carrier to the first stage of heat exchanger by hydraulic pulses with change of rate of heat carrier from state of rest to maximum possible with synchronous intermittent supply of pulse mechanical vibrations of resonant frequency, immediately to heat exchanger steel structure.
