Low-temperature evaporative crystallization apparatus

Abstract

The present invention discloses a low-temperature evaporative crystallization apparatus. The apparatus comprises: a curtain type evaporator, which comprises an evaporation chamber, a plurality of evaporation modules and a water distribution mother pipe, wherein each evaporation module comprises a plurality of curtain cloth assemblies arranged in parallel at an equal, and each curtain cloth assembly comprises a hydrophilic cord fabric and a water distribution branch pipe; a crystallizing pond, which is arranged at the bottom of the evaporation chamber and used for collecting materials and crystals falling from the hydrophilic cord fabric; an air exhausting mechanism, which communicates with the evaporation chamber and used for generating negative pressure to exhaust evaporated steam in theevaporation chamber; and a heating device, which is separately connected with the water distribution mother pipe and the crystallizing pond and used for heating the materials in the crystallizing pondand then conveying the materials into the water distribution mother pipe. According to the invention, evaporation and crystallization of the materials can be achieved at low temperature and natural atmospheric pressure, and the evaporative crystallization device has the advantages of low operation pressure, simple structure, convenience in operation and the like.
