Abstract

Vacuum flash cooling continuous crystallization device, including raw material storage tank, raw material pump, self-evaporator, No. 1 vacuum crystallizer, No. 2 vacuum crystallizer, No. 3 vacuum crystallizer, hydrocyclone, slurry barrel, centrifuge, etc. It is characterized in that: the raw material storage tank is sequentially connected with a raw material pump, a self-evaporator, a No. 1 vacuum crystallizer, a No. 2 vacuum crystallizer, a No. 3 vacuum crystallizer, a hydrocyclone, a slurry tank, and a centrifuge. The top of the cooler is connected to the No. 1 surface cooler through a pipeline, the No. 1 surface cooler is connected to the No. 1 water ring vacuum pump through a pipeline, the No. No. 1 vacuum crystallizer slurry inlet, No. 1 vacuum crystallizer top is provided with a No. 1 steam jet vacuum pump. Compared with the batch crystallization, the comprehensive energy consumption of the present invention is 40% of that of the batch crystallization. Scar can be produced continuously for a long time.

Description

technical field [0001] The invention relates to an evaporation crystallization device, in particular to a vacuum flash cooling continuous crystallization device. Background technique [0002] At present, the intermittent crystallization process in cooling crystallization accounts for more than 95% of all domestic industries. The labor productivity is low, mainly due to manual operation, the product quality cannot be guaranteed, and the comprehensive energy consumption is high. The supporting refrigeration system and brine low-temperature water system account for The ground area is large, the power consumption is large, and the corrosion is high. Some of them adopt the freeze crystallization process, and the pipe plugging and scarring are prominent. They need to be cleaned frequently, and the labor intensity is high. flour), dehydration is difficult, and caking has seriously affected the quality of the product. Contents of the invention [0003] Aiming at the above problem...
