Description
Technical field
The present invention relates to a kind of capsule cylindrical microwave flash distillation plants for heavy metal containing wastewater treatment, belong to evaporation process
Heavy metal wastewater thereby technical field.
Background technology
With the rapid development of China's modern industry, the heavy metal pollution problem getting worse in industrial wastewater.How to have
Effect administers heavy metal pollution, these heavy metal wastewater therebies of efficient process, and be allowed to recycling, and have become that people pay close attention to jointly asks
Topic.Evaporation is one of effective way for handling heavy metal ion-containing waste water.As one of important chemical engineering unit operation, evaporation is
With the method for heating, make solution under fluidized state by moisture therein or with the vaporization of volatile solvent content.Therefore, steam
Hair process is the process of a heat transfer, for metallurgical, chemical field, evaporates required heat and is mainly derived from heat
It exchanges, is one of operating unit of energy consumption maximum.
Current vaporising device can be divided into single-action, multiple-effect, indirect steam compression and Multi-stage flash hairdo, multiple-effect multiple stage flash evaporation
Formula etc..Single effect evaporation efficiency is low, and in order to improve evaporation efficiency, vaporising device gradually develops to multiple-effect evaporation.Multi-effect evaporation system
More complicated, triple effect evaporation needs three pumps, three evaporators, three sets of heat-exchange systems, and these equipment are required for high temperature resistant, resistance to
It presses and corrosion-resistant, manufacturing cost is higher.Therefore, in existing vaporising device and technique, generally existing heat exchange efficiency is low,
The technical barriers such as easy fouling, cost of investment height, equipment flowsheet length and high energy consumption.
