Abstract

The invention relates to a forced-circulation evaporator. The forced-circulation evaporator is used for solving the problem that materials of a conventional forced-circulation evaporator easily block the inner part of a pipeline. The forced-circulation evaporator is characterized in that the lower part of a separator is provided with a discharging pipeline which is connected to a discharging pump; the discharging pipeline is also connected to a cyclone, the side tangential part and the upper part of the cyclone are both connected to the discharging pipeline through a pipeline, the pipeline circulation is formed between the discharging pipeline and the cyclone, and the bottom of the cyclone is connected to a material receiving device through the pipeline. The forced-circulation evaporator has the advantages that the cyclone is additionally arranged on the discharging pipeline, so that the concentration of liquid in the whole evaporator is relatively low; after the liquid passes through the cyclone during discharging, particles with heavy density outflow from a bottom flowing port, and liquid with light density returns from an overflow pipe, and when the liquid flows into the receiving device, the concentration is very high, thus the condition that the relatively high concentration of liquid in the pipeline in the earlier stage causes the blockage of the pipeline is avoided.
