Abstract
The invention discloses a method and a device for reducing energy losses of a drain flash tank. An input connecting opening of the drain flash tank is designed into an ejector device; an outlet end of the ejector device is a horn opening; an inlet of the ejector device is provided with a drain connecting opening and a demineralized water connecting opening; the axis of the drain connecting opening and the horn opening of the outlet end are coaxial; the demineralized water connecting opening is perpendicular to the axis of the demineralized water connecting opening and is located behind the demineralized water connecting opening; the demineralized water is sucked into the ejector device to be mixed with the drain through the negative pressure produced behind a nozzle when the drain is ejected from the nozzle and the decompression and cooling is performed on the drain through the demineralized water so as to reduce the intensity of the steam and water separation in the flash tank and reduce the emissions of the secondary steam and the consumption of the demineralized water. According to the method and the device for reducing the energy losses of the drain flash tank, the decompression and cooling is performed on the drain through the ejector device which is arranged at the position of an inlet of the flash tank so as to reduce the intensity of the steam and water separation in the flash tank and reduce the emissions of the secondary steam and the consumption of the demineralized water.
