Abstract
The invention provides a falling-film evaporator. The falling-film evaporator comprises an outer shell, an upper partition plate, a lower partition plate and a heat exchange tube, wherein the upper partition plate, the lower partition plate and the heat exchange tube are vertically arranged in the outer shell; the upper partition plate and the lower partition plate are used for dividing an inner cavity of the outer shell into a first cavity, a second cavity and a third cavity; the first cavity and the second cavity are formed on two sides of the upper partition plate; the second cavity and the third cavity are formed on two sides of the lower partition plate; one end of the heat exchange tube is inserted into the upper partition plate and communicated with the first cavity; the other end of the heat exchange tube is inserted into the lower partition plate and communicated with the third cavity; a feeding opening is formed in the first cavity; the third cavity is provided with a discharging tube; the falling-film evaporator also comprises an evaporation chamber; an outlet of the discharging tube is formed in the evaporation chamber; a jet pump is arranged at the upper part of the evaporation chamber; a discharging opening is formed in the lower part of the evaporation chamber. The falling-film evaporator is capable of recycling heat energy and introducing recycled hot steam into a next-level falling-film evaporator, so that energy is greatly saved.
