Abstract
The utility model relates to a kind of heating or refrigerating unit of high-purity rare-earth feed liquid, and described device comprises with lower part: material liquid tank, recycle pump, carbon tube, circulation line, temperature control unit, opening for feed and discharge port.High-purity rare-earth feed liquid iterates through carbon tube inside under the Circulation of pump, adopt outside indirect heating or cooling feed liquid in carbon tube outside, heating or process of cooling temperature control to be realized by least one mode in feedback heating after thermocouple temperature measurement or refrigerating unit and startup recycle pump.Carbon tube heating or water cooler material used are graphite, particularly high conductive graphite, have the fast and corrosion resistant advantage of heat transfer rate, and avoid heating or polluting feed liquid problem in process of cooling.
Description
Technical field
The utility model relates to a kind of device of indirect heating high-purity rare-earth feed liquid and technique belongs to rare-earth smelting and high-purity rare-earth production of chemicals field.
Background technology
In traditional rare-earth precipitation reaction process, in order to heat or cool feed liquid, generally in a kettle. by coil pipe, steam indirect heating or cold water is adopted indirectly to cool feed liquid, there is shortcoming in which: be not easy to automatic precise control and control feed temperature, energy consumption is higher.In recent years, gradually for rare earth feed liquid heating, but there is thermal oil domestic demand interpolation diphenyl mixture and the shortcomings such as easy blast in thermal oil coil pipe reacting by heating groove.In addition, also there is material corrosion resistant problem in the heating of reactor coil pipe or the type of cooling, service life of equipment is restricted, and product quality reduces because of material corrosion, and this type of heating also exists input comparatively greatly, the problems such as occupation area of equipment is large.
Utility model content
The utility model provides as solution of the above problems, and content of the present utility model is as follows:
Described device comprises with lower part: material liquid tank, recycle pump, carbon tube, circulation line, temperature control unit, opening for feed and discharge port.
The heat conductivity graphite material of the preferred thermal conductivity of graphite more than (200w/m.k) that described carbon tube adopts.
Described carbon tube preferentially adopts high purity graphite material.
Described carbon tube is made up of in serial or parallel connection mode one or more carbon tube.
Described material liquid tank and circulation line material are the one in polypropylene material or polytetrafluoro material, and outside is provided with thermal insulation layer, and circulation line is connected by flange method with carbon tube.
Described heating unit can adopt steam, oil bath or far infrared mode to the outside indirect heating of carbon tube in carbon tube outside.
Described refrigerating unit can adopt recirculated cooling water, refrigeration agent indirectly to cool internal liquid in carbon tube outside in carbon tube outside.
In described heating or refrigerating unit, after its temperature adopts temperature control unit thermometric, realize by regulating carbon tube indirect heating or refrigerating unit and pass termination of pumping recycle pump.
The beneficial effects of the utility model are as follows:
1, the material that carbon tube is used is graphite, particularly high conductive graphite, and having the material that heat transfer rate is fast and corrosion resistant advantage is used is high purity graphite, has the advantages that not pollute feed liquid.
2, avoid polluting feed liquid in heating or process of cooling, even if there are wearing and tearing or damaged in graphite in feed liquid circulation and heating or process of cooling, feed liquid is entered with slag form, also can realize decomposing in filtration subsequently or rare earth carbonate or oxalate calcination reaction process, the corrosion resistant problem of metal plate type interchanger can be solved
3, integral device is simple, and floor space is little, less investment, and the temperature easily realizing feed liquid controls, and avoids using enamel reaction still heating or cooling apparatus conveying trouble, the problem that equipment investment is large.
