Description

A kind of hollow disk bar cooling continuous crystallizer of high effective
Technical field
The utility model relates to a kind of hollow disk bar cooling continuous crystallizers of high effective of field of chemical equipment.
Background technique
It is well known that the crystallisation by cooling of material is medicine, the highly important unit operation of the industries such as chemical industry, food, crystallization Quality, directly affect the yield and quality of product.
With the most use at present is kettle type crystallization device, and this equipment is to add cooling jacket outside an autoclave body with stirring Crystallisation by cooling is carried out to material, it is cooling outer in addition to adding cooling jacket to carry out other than autoclave body, then cooling coil etc. pair is added in kettle Material carries out crystallisation by cooling.Though this traditional equipment can solve common crystallisation problems, there is also shortcomings:
First, due to cooling using collet, crystallization is first since kettle wall, so that crystalline object is tied in kettle wall, seriously first When thick crystalline object can be formed on kettle wall, largely effect on heat transfer efficiency;Although can by improve speed of agitator method come It reduces the problem of being crystallized on kettle wall, but crystallizes the also limitation by speed of agitator in many cases, speed of agitator is too fast, meeting Making the partial size of crystal grain greatly reduces, and influences the filtration washing drying process of next step, and for wishing to obtain compared with big crystal grain Occasion is even more improper.In addition autoclave stirred crystallization, agitating paddle, which is generally difficult to, scrapes wall stirring, can not will thus tie Crystal grain on kettle wall scrapes, to influence heat-transfer effect.
Second, common crystallization kettle is often preferable in the crystallization effect close to external cooling reactor wall, and close to kettle center Material crystallization is very slow, causes crystal grain uneven, whole crystallization rate is slower.
Third, for the crystallization kettle of cooling coil is added in kettle, though it is greatly improved film-cooled heat, due to cooler pan Pipe be it is static, first crystallization is formed outside static coil pipe, seriously affect heat-transfer effect.It can be largely effected on after additionally incorporating coil pipe The mixing effect of crystallization kettle, scraping wall stirring is even more that can not accomplish, after forming more crystalline object on kettle wall and on coil pipe, is passed Thermal effect is worse, prevents slurry from being successfully completely exhausted out.
4th, since the bottom of crystallization kettle is often standard elliptical head, thus, crystalline solid higher for material concentration More crystallization kettle, often discharge is not thorough, and partially crystallizable solid, which can remain in kettle, can not arrange, and influences yield and energy consumption.
For above-mentioned common kettle type crystallization machine there are the shortcomings that, research institution once had developed in horizontal that turn disk cold in the industry But crystallizer, it is horizontal in turn comb cooling crystallization machine, it is horizontal in turn ribbon cooling crystallization machine, Horizontal hollow screw-pushing type continuous Cooling crystallization machine, it is vertical in turn comb cooling crystallization machine, it is vertical in turn ribbon cooling crystallization machine etc., mention crystalline rate Height saves energy consumption and reduces crystallization time.
Above-mentioned crystallizer is compared with common kettle type crystallization machine, though efficiency increases, during crystallization, rotation fortune The cooling surface of dynamic component still has crystal to bear, once cooling surface has Crystallization, even most thin also will affect cooling effect, To the occasion of gap operating, this phenomenon is not also very prominent, because the crystallized stock of next group heat can be this layer knot when being added Dissolution of crystals falls, but the case where to continuous crystallisation, the above situation will protrude very much, because of the crystalline solid meeting of cooling surface It gets deeper and not can be removed and seriously affect cooling effect.Thus, it would be highly desirable to which cooling table can be made during crystallization by developing one kind Face remains completely, to improve the crystallizer of crystalline rate.
