Abstract
The utility model discloses a device for removing calcium formate in neopentyl glycol by calcium method, which includes an evaporator cell 1, a downcomer 2, a sedimentation chamber 3, a magnetic stirrer 4, a forced-circulation pump 5, a heater 6 and some necessary pipe joints; The bottom of the evaporator cell 1 is connected with the top of the sedimentation chamber 3, and the downcomer 2 is located in the sedimentation chamber 3 and is communicated with the bottom of the evaporator cell 1, and the magnetic stirrer 4 is located at the bottom of the sedimentation chamber 3, and one end of the forced-circulation pump 5 is connected with the sedimentation chamber 3 through pipe, and the other end is connected with the lower end of the heater 6, and the upper end of the heater 6 is connected with the evaporator cell 1 through pipe. The utility model not only can be used for removing calcium formate in neopentyl glycol by calcium method, but also can be used for removing sodium formate in neopentyl glycol by sodium method, compared with the prior art, the device can used for continuous evaporation concentration and separation of calcium formate with high heat transfer efficiency, fast evaporation speed, and is good for improving yield of neopentyl glycol and quality of calcium formate.
Description
Technical field
The utility model relates to a kind of tripping device that removes that uses in the chemical process, particularly a kind of device that removes calcium formiate in the calcium method neopentyl glycol.
Background technology
Most sodium method and the hydrogenation methods of using of the production of present domestic neopentyl glycol, and calcium method neopentyl glycol is to use calcium hydroxide to make condensing agent, and cost of material is cheap, and the price of by product calcium formiate is than the price height of sodium formiate, two kinds of technologies of sodium method and calcium method compare, and the calcium method has stronger market competition advantage.But calcium method neopentyl glycol in process of production, because the solubleness of calcium formiate is less, very easily stops up the tubulation of well heater in the spissated process of stripping, and heat transfer efficiency is low, velocity of evaporation is slow, is unfavorable for improving the quality of the yield and the calcium formiate of neopentyl glycol, brings great inconvenience to continuous production.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and provide a kind of device that removes calcium formiate in the calcium method neopentyl glycol, its energy consecutive evaporation to concentrate and separate calcium formiate continuously, and heat transfer efficiency height, velocity of evaporation is fast, helps improving the quality of the yield and the calcium formiate of neopentyl glycol.
The technical solution of the utility model is: a kind of device that removes calcium formiate in the calcium method neopentyl glycol, it is formed by evaporator room, downtake, settling pocket, magnetic stirring apparatus, forced circulation pump, well heater and pipe connection that some are necessary, the bottom of evaporator room is connected with the top of settling pocket, downtake is positioned at settling pocket and is communicated with the bottom of evaporator room, magnetic stirring apparatus is positioned at the bottom of settling pocket, one end of forced circulation pump is connected with settling pocket by pipeline, the other end is connected with the lower end of well heater by pipeline, and the upper end of well heater is connected with evaporator room by pipeline.
The utility model both can be used for removing the calcium formiate in the calcium method neopentyl glycol, simultaneously also can be used for removing sodium method neopentyl glycol sodium formiate, the content of neopentyl glycol is less, helps improving the quality of the yield and the calcium formiate of neopentyl glycol, compared with prior art has following advantage:
1, the utility model heat transfer efficiency height helps the separate and subside of calcium formiate again;
2, the utility model does not stop up the heating tubulation, and velocity of evaporation is fast;
3, the utility model can realize that consecutive evaporation concentrates and the purpose of separating calcium formiate continuously.
Below in conjunction with the drawings and specific embodiments detailed content of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of device that removes calcium formiate in the calcium method neopentyl glycol, it is by evaporator room 1, downtake 2, settling pocket 3, magnetic stirring apparatus 4, forced circulation pump 5, well heater 6 and some necessary pipe connection form, the bottom of evaporator room 1 is connected with the top of settling pocket 3, downtake 2 is positioned at settling pocket 3 and is communicated with the bottom of evaporator room 1, magnetic stirring apparatus 4 is positioned at the bottom of settling pocket 3, one end of forced circulation pump 5 is connected with settling pocket 3 by pipeline, the other end is connected by the lower end of pipeline with well heater 6, and the upper end of well heater 6 is connected with evaporator room 1 by pipeline.
Principle of work of the present utility model is: the import that the condensated liquid of calcium method neopentyl glycol enters forced circulation pump 5 continuously, after heater via 6 heating, neopentyl glycol enters dehydration tower with the water evaporation in evaporator room 1, the condensated liquid that is concentrated enters settling pocket 3 from evaporator room 1 through central downtake 2, calcium formiate is deposited to the bottom of settling pocket 3 and separates with clear liquid in settling pocket 3, the clear liquid that contains more neopentyl glycol is sent to well heater 6 heating through recycle pump 5, be recycled to evaporator room 1 evaporation, so come and go, the moisture of condensated liquid separates continuously with neopentyl glycol and enters dehydration tower.In order to prevent that calcium formiate is at settling pocket 3 bottom settlingss, the magnetic stirring apparatus 4 that is located at settling pocket 3 bottoms ceaselessly stirs, the calcium formiate suspension that stirs into pulpous state is sent to whizzer and separates calcium formiate from settling pocket 3 bottoms, separate the circulation tube of the mother liquor Returning evaporimeter of calcium formiate, calcium formiate obtains 99% calcium formiate through recrystallization.
