DEVICE FOR CLEANING FLUE GASES FROM WATER VAPOR Russian patent published in 2021 - IPC B01D53/60 F23D11/10 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering and is intended for cleaning flue and condensate emissions in factory pipes, pipes of nuclear power plants (NPP) and thermal power plants (TPP). The device for cleaning flue gases from water vapor is characterized by the fact that a dome is installed at the outlet mouth of the chimney, open to the outlet of the purified gas from above, and contains a ring of air nozzles located in it in the direction of gas movement along the circumference of the pipe, a gas temperature sensor, grooves for distillate runoff at two levels with a displacement of levels relative to each other and at an angle to the horizon. It also contains a perforated package of pipes, on which a multi-layer drip grid and a “dew point” sensor determining gas humidity are placed. Outside the chimney there is a control panel, a compressor, the outlet of which is connected to the inlet of the Ranque tube, the “hot” outlet of which is connected to the ring of air nozzles through an adjustable valve and a pipeline, the “cold” outlet of the tube through another control valve and another pipeline is connected to a package of perforated tubes. The sensors, valves, compressor and the Ranque tube are connected to the control panel of the device. The air nozzles are made with external air ejection and are located with outlet openings in the direction of gas movement, and an additional fan with a drive mechanism connected to the device control panel is installed in the lower part of the dome.

EFFECT: aggregation of all units for the task of separating water vapor from flue gases in one dome housing provides autonomous operation and installation of the dome for already operating factory pipes, NPP and TPP pipes without redesigning the technology of their use.
