Abstract

The invention discloses a low-temperature multi-effect evaporative crystallization process and crystallization equipment, relates to the technical field of low-temperature multi-effect evaporative crystallization, and aims to solve the problem of poor reaction evaporation effect caused by unstable pressure of a low-pressure environment during evaporation of existing high-salinity wastewater. A pumping mechanism is arranged on the upper end face of the feeding device and fixedly connected with the reaction device through a first connecting conveying pipeline, a first pressure pointer meter is arranged on the upper end face of the first connecting conveying pipeline, and a reinforcing end is arranged on the upper end face of the reaction device. A third pressure pointer gauge is arranged on one side of the upper end face of the reinforcing end, one end of the filter pipe equipment is fixedly connected with the reaction equipment through a main conveying pipeline, a third connecting conveying pipeline is arranged at the other end of the filter pipe equipment, and a buffering mechanism is arranged at one end of the third connecting conveying pipeline. And a second connecting conveying pipeline is arranged on the lower end surface of the buffer mechanism.

Description

Technical field [0001] The present invention relates to the field of low-temperature multi-effect evaporative crystallization technology, specifically a low-temperature multi-effect evaporation crystallization process and crystallization equipment. Background [0002] Evaporative crystallization: heating the evaporative solvent, so that the solution from unsaturated to saturated, continue to evaporate, excess solute will be crystallized precipitation, called evaporative crystallization. Evaporation refers to the process of separating the solvent from the solute by heating up the solvent in solution; Crystallization is the process by which solutes polymerize into solids. Evaporation is often accompanied by filtration. Here are several common filtration methods: 1, atmospheric pressure filtration, the instruments used are: glass funnel, small beaker, glass rod, iron frame table and so on. The problems to be noted are: when stacking the filter paper, try to keep it as close as possi...
