Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a spontaneous vibration falling film evaporator device. Background Art

[0002] The falling film evaporator is a highly efficient, single-pass, non-circulating film evaporation device. Existing equipment uses an energy-saving and environmentally friendly process flow, using a pressure pump to pump the mixed material into the top of the equipment through a pipeline. The material is then evenly distributed through an automatic adjustment and distribution device and falls into the evaporation heat exchange device. The waste heat circulating water vapor is then used for heat exchange in the heat exchanger, raising the temperature of the mixed material to various boiling points before entering the distillation tower for separation, thereby achieving the purpose of recycling useful materials, removing wastewater, and energy conservation and environmental protection. However, due to the different concentrations and impurities of the materials, when the materials enter the distributor at the top of the reboiler for distribution, blockage will occur over time, making it necessary to manually enter the equipment for cleaning, thereby increasing the possibility of production stoppages and the labor intensity of manual labor, thereby reducing the working efficiency of the falling film evaporator. Therefore, it is necessary to provide a spontaneous vibrating falling film evaporator device to solve the above problems. Utility Model Content
