[0022] Specifically, the high-temperature steam condensate recovery and flash steam compression recovery device includes a flash tank 1, and a steam inlet pipe 2 for conveying steam condensate to the inside of the flash tank 1 is provided on one side of the flash tank 1, which is used to collect high-temperature condensate. An extraction component for extracting condensate is provided on one side of the flash tank 1, so that the collection and reuse of condensate can be realized. The extraction component includes a centrifugal pump 4, which is connected to the flash tank 1 through a pumping pipe 3. Therefore, when in use, the centrifugal pump 4 extracts the condensate inside the flash tank 1 through the pumping pipe 3, so that the collection and reuse of condensate can be realized, and the use effect is better. It is known that when the steam condensate enters the flash tank 1, due to the principle of expansion and pressure reduction, part of the steam condensate becomes secondary steam (flash steam), and the secondary steam will be concentrated in the upper space of the flash tank 1. A water vapor separation component 7 is provided inside the flash tank 1, and a water vapor separation component 7 is installed inside the flash tank 11 to further improve the water vapor separation effect in the secondary steam.

When the centrifugal pump 4 is automatically started, it enters the three-in-one regulating valve 6 through the outlet of the centrifugal pump 4. The three-in-one regulating valve 6 is started, and most of the steam condensate is supplied to the boiler (power plant). Part of the steam condensate returns to the cavitation eliminater at the inlet of the centrifugal pump 4 through the jet (reflux balance pipeline) pipeline, ensuring that the pressure of the inlet pipeline of the centrifugal pump 4 is higher than the pressure at the saturated temperature of the hot water, effectively preventing the steam condensate at the inlet of the centrifugal pump 4 from vaporizing, achieving the purpose of cavitation elimination, so that the centrifugal pump 4 can absorb high-temperature steam condensate.

Therefore, when the drive system 14 is damaged or needs maintenance, the drive system 14 can be smoothly disassembled from the base 13, and the use effect is better.
