BATCH VACUUM DEAERATOR FOR HEATING AND HOT WATER SYSTEMS Russian patent published in 2023 - IPC F24D3/02 

FIELD: thermal power engineering.

SUBSTANCE: invention can be used to remove gases from the feed water of heating and hot water supply systems simultaneously with the introduction of reagents for coordinated water treatment. Vacuum intermittent deaerator of a heating and hot water supply system includes a control system, a deaeration chamber 1, in the upper part of which a nozzle 2 is installed for spraying raw water, a valve 3 for supplying water to the nozzle 2 and a valve 4 for discharging gases, and at the bottom - a sensor 6 for the lower water level, outlet 8 connected to pump 7, and check valve 11. According to the invention, in the upper part of the deaeration chamber 1 at a level of 0.1 to 0.5 of its height from the top, a deaeration start sensor 5 is additionally installed, and a membrane expansion tank 10 of the deaerated water supply is additionally mounted behind the pump 7 to displace the vapor-gas mixture, behind which is located non-return valve 11 connected to line 9 for supplying prepared water to the consumer.

EFFECT: improving the quality of deaerated water.
