Description
Technical field:
The utility model belongs to technical field of chemical, relates to a kind of multitube falling-film crystallizer.
Background technology:
As a kind of important chemical engineering unit operation, crystallization has important effect in the separation and purification process of product.Crystallization process is generally divided into solution crystallization, fusion-crystallization, precipitated crystal and distillation crystallization four class.Film-falling crystallization is as the one of fusion-crystallization, be according to separate substance between freezing point difference and realize be separated crystallization process, liquid material obtains high purity product in a crystallizer after crystallization, sweating, have separable go out high purity product, operating temperature low, pollute the advantages such as little, energy-conservation, be often widely used in the refining purification of oil, chemical industry, medicine and other fields product.
Summary of the invention:
The purpose of this utility model is to provide that a kind of structure is simple, efficiency is high, operating flexibility is large, can realize the multitube falling-film crystallizer that crystallization condition is determined in laboratory fast.
A kind of multitube falling-film crystallizer described in the utility model, comprise: thermal insulation layer (1), heat exchanger tube (2), heat transferring medium entrance (4), entrance temperature-measuring casing (5), heat transferring medium outlet (6), outlet temperature-measuring casing (7) and N number of film-falling crystallization group (3), wherein, N >=2, it is characterized in that: described thermal insulation layer (1) is attached on heat exchanger tube (2), described heat exchanger tube (2) top offers heat transferring medium outlet (6), heat exchanger tube (2) bottom offers heat transferring medium entrance (4), outlet temperature-measuring casing (7) is provided with near described heat transferring medium outlet (6), entrance temperature-measuring casing (5) is provided with near described heat transferring medium entrance (4).
Described film-falling crystallization group (3) is made up of crystallizer (8), top connection (9), lower contact (10) and U heat exchange (11), the import and export of U heat exchange (11) are through top connection (9) and be connected as a single entity with top connection (9), and N number of film-falling crystallization group (3) is evenly distributed on the center of heat exchanger tube (2).
The beneficial effects of the utility model are: this multitube falling-film crystallizer structure is simple, easy to operate, N number of film-falling crystallization group (3) is all placed in same heat exchanger tube (2), crystallizer (8) outer wall temperature control is even, and only need a heat-exchange circulating device, save cost, simultaneously, the import and export of U heat exchange (11) can independent external heat-exchange circulating device, the effect of crystallization under investigation different temperatures difference, also connect with external circulating device after can mutually connecting, investigate the collimation of experiment, operating flexibility is large again.
