Description
Technical field
The utility model relates to a kind of crystallizer, belongs to fractional crystallization technical field.
Background technology
A kind of trough-shaped container of crystallizer, wall is provided with chuck or device built with coiled pipe, in order to solution in heating or cooling bath.Crystallization tank can be used as crystallizing evaporator or cooler crystallizer.For improving crystal production intensity, agitator can be set up in groove.Crystallization tank can be used for continued operation or intermittently operated.The crystal that intermittently operated obtains is comparatively large, but crystal is easily linked to be druse, entrainment mother liquor, affects product purity.This mold structure is simple, and production intensity is lower, is applicable to the production of be pilot (as chemical reagent and biochemical reagents etc.).The type of crystallizer is a lot, and the method obtaining hypersaturated state by solution can divide crystallizing evaporator and cooler crystallizer; Can decomposition mother solution circulation crystallization device and magma (i.e. the mixture of mother liquor and crystal) circulation crystallization device by the type of flow; Continuous crystalizer and periodic crystallisation device can be divided by mode of operation.
The crystallizer of current domestic application is owing to adopting chuck cooling, and crystallization, first from still wall, makes crystalline thing first tie at still wall, can form thick crystalline thing, greatly affect heat transfer efficiency time serious on still wall.Though the method by improving speed of agitator reduces the problem of crystalline thing knot wall on still wall, but paddle is generally difficult to accomplish that scraping wall stirs, under a lot of situation, crystallization is also subject to the restriction of speed of agitator, speed of agitator is too fast, size of microcrystal can be made greatly to reduce, affect next step filtration washing operation.Crystallization kettle is often better near external refrigeration still wall crystallization effect, and the material crystallization at close still center is very slow, and cause crystal grain uneven, overall crystallization rate is very slow.In addition, higher for material concentration, the crystallization kettle that crystalline solid is more, often discharge is not thorough, and partially crystallizable solid can remain in row in still and not go out, and affects output and energy consumption.
Utility model content
