Background

Flash evaporation is the phenomenon that after high-pressure saturated liquid enters a container with relatively low pressure, the saturated liquid becomes part of saturated steam and saturated liquid under the container pressure due to the sudden pressure reduction;

the boiling point of the material is increased along with the increase of the pressure, and the lower the pressure is, the lower the boiling point is, so that the high-pressure high-temperature fluid can be decompressed to reduce the boiling point and enter a flash tank, at the moment, the fluid is higher than the boiling point under the pressure, the fluid is rapidly boiled and vaporized in the flash tank and is subjected to two-phase separation, and the device for gasifying the fluid is not the flash tank but a decompression valve, and the flash tank is used for providing a space for rapidly gasifying the fluid and separating vapor and liquid;
