Description
Technical field
The utility model belongs to chemical technology field, relates to a kind of condensation reaction still, is specifically related to a kind of condensation reaction still preparing trimethylolpropane.
Background technology
In Chemical Manufacture, reactor is made up of kettle, charging aperture, discharging opening, chuck, agitating device, transmission device, gland seal device etc.Agitating device can use multiple impellers leaf, also can match arbitrarily according to the requirement of user.The temperature of reactor is usually higher, and need cooling water to cool, prior art is normally by passing into cooling water to lower the temperature to reacting kettle jacketing, and cooling water passes into from chuck end opening, and from chuck discharge suitable for reading, cooling effect is unsatisfactory:
(1) when reactor has high temperature, directly pass into cooling water, cooling water meeting transient evaporation, the steam of generation can produce water hammer by knock-on reaction still wall, the easily bad reactor wall of shake;
(2) steam and cooling water flow simultaneously in pipeline, very large to the corrosion of pipeline;
(3) temperature reached required for cooling is wayward.
Utility model content
In order to overcome above-mentioned defect, the purpose of this utility model is to provide a kind of condensation reaction still preparing trimethylolpropane.
The utility model adopts following technical scheme:
Prepare a condensation reaction still for trimethylolpropane, it comprises kettle, the agitator be made up of multiple impellers leaf, chuck, interior endless tube and cooling fluid automatic regulating valve, motor and charging aperture; Chuck, interior endless tube and cooling fluid automatic regulating valve form cool cycles passage, and chuck is the interlayer of kettle body wall, and interior endless tube is positioned on kettle body wall.
The inner bottom part of kettle is provided with stirring support, and the least significant end of agitator supports by stirring support.
The paddle of agitator is three layers, namely stirs upper strata blade, stirs middle level blade and stir lower leave.
Charging aperture is divided into hutanal charging aperture, formaldehyde charging aperture, calcium hydroxide charging aperture and water inlet, and each charging aperture is arranged on the upper surface of kettle.
Chuck is connected with inner ring cooling water pipe by the chuck cooling water pipe outside kettle with interior endless tube, and cooling fluid automatic regulating valve is arranged on connecting pipe.
During cooling, cooling water can be passed into from chuck and interior endless tube lower end, discharge from reactor upper end; Cooling water automatic regulating valve can be used for regulating cooling water.
The utility model successful, feed intake accurately convenient, cooling effect is better, ensures normally carrying out of the interior reaction of reactor; In addition, can human resources be saved, reduce enterprise's production cost etc.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: kettle 1, agitator 2, chuck 3, interior endless tube 4, cooling fluid automatic regulating valve 5, motor 6, charging aperture 7.
Detailed description of the invention
The utility model specifically can be implemented by the technology illustrated in technical scheme, and by the following examples can the utility model will be further described, but scope of the present utility model is not limited to following embodiment.
Reactor of the present utility model, it comprises reaction kettle body 1, agitator 2, the cool cycles passage be made up of chuck 3, interior endless tube 4, cooling fluid automatic regulating valve 5, motor 6, charging aperture 7 and discharging opening.
Paddle on agitator 2 is multiple layers of stirring blades, be preferably three layers of paddle, namely stir upper strata blade 21, stir middle level blade 22 and stir lower leave 23, agitator lowermost end has the stirring support 24 that can stand on reactor inner bottom part regularly, can ensure uniform stirring in kettle 1.
Chuck 3 is connected by the pipeline outside kettle with interior endless tube 4, and cooling fluid automatic regulating valve 5 is arranged on this pipeline.
Charging aperture 7 is divided into hutanal charging aperture, formaldehyde charging aperture, calcium hydroxide charging aperture and water inlet, and each charging aperture is arranged on the upper surface of kettle 1.When the product needed is tri hydroxy methyl butane, the raw material that charging aperture 7 is put into has hutanal and formaldehyde, and drops into calcium hydroxide as catalyst, drops in formic acid and neutralization reaction, obtains trimethylolpropane crude product reactant liquor.
During concrete production (as shown in Figure 1), when needs cool reactor, open cooling water, cooling water enters chuck 3 and interior endless tube 4 respectively.Temperature in the kettle is high, the temperature in still effectively can be reduced after cooling water enters interior endless tube 4, so, when cooling water in chuck 3 runs into by the reactor of interior endless tube 4 water quench, both diminish at temperature difference, and cooling water evaporating capacity reduces, and the steam of generation also reduces, not easily shake bad reactor, the corrosiveness of pipeline is also slowed down.Also be provided with cooling fluid automatic regulating valve 5 outward at still, automatically can regulate the unlatching of cooling fluid, closed and uninterrupted, not only accurate but also punctual, cooling effect is better, and that reacts in guarantee reactor normally carries out; In addition, can human resources be saved, reduce enterprise's production cost.
