Abstract

See full text

A vapor source system based on vapor-liquid ejector supercharging combined with flash vaporization technology belongs to the technical fields of waste heat utilization and steam generation. The system comprises a vapor-liquid ejector, a flash vaporization tank and a intermediate heat exchanger, wherein the vapor-liquid ejector uses high-pressure steam to raise temperature and pressure of low-pressure water absorbed from the flash vaporization tank; the pressure-increased water is flashed into low-pressure saturated steam after entering the flash vaporization tank; the saturated water which is not flashed is collected at the bottom of the flash vaporization tank. The system generates multiple low-pressure flash vaporization saturated steam with a small portion of high-pressure steam, and realizes the recovery and utilization of waste heat such as flue gas of boiler, improves the economy of thermal process, and provides a flexible and adjustable vapor source for heavy oil thermal recovery, seawater desalination or sewage treatment equipment.
