On-line high-efficientthree-phase flow evaporation concentration device with solid particle for preventing liquid on wall and operation method

An in-line three-phase tream evaporation concentrator able to effectively prevent surface sticking features that a kind of physiological inertial solid particles are added to vapor-liquid stream evaporation concentrator to form a naturally circulating three-phase fluidized bed, where the said solid particles can prevent the surface sticking phenomenon. The said concentrator has heater, heating pipe, separation chamber, vapor and condenser, condensed liquid tank, vacuum buffer tank, vacuumizing pump, and discharger.
