DEVICE FOR IMPULSE CLEANING OF HEAT EXCHANGE SURFACES Russian patent published in 2022 - IPC F28G9/00 B08B9/32 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering and can be used in devices for pulsed cleaning of heat exchange surfaces. A device for pulse cleaning of heat exchange surfaces, containing a group of heat exchangers, a cooler with a collection tank connected to its outlet, which, in turn, is connected by means of the first check valve to a suction pipeline connected to a circulation pump, which is connected via a discharge pipeline to the inlet of a group of heat exchangers, a bypass pipeline with a sealed container connected to it, while the inlet of the bypass pipeline is connected by a second check valve to the discharge pipeline, and the outlet is connected to the suction pipeline by means of a valve, equipped with a three-way valve for switching modes and a shock assembly, and the sealed container is made in the form of a hydraulic accumulator , and the input of the three-way valve for switching modes is connected to the output of a group of heat exchangers, the first output of the three-way valve for switching modes is connected directly to the inlet of the cooler, and the second one the outlet is connected to the cooler inlet by means of a shock assembly.

EFFECT: improving efficiency and simplifying the design of the device.
