Description
Technical field:
The utility model relates to a kind of rectifying device that is used for Chemical Manufacture, refers to a kind of chemical industry rectifying still that is used for higher boiling, high-solidification point, high-viscosity material especially.
Background technology:
Rectifying is the important component part of Chemical Manufacture technology.At present, employed rectifying device mainly is made up of rectifying column, reboiler, condenser, backflash, reflux pump etc. in the Chemical Manufacture, and this class rectifying device is applicable to the rectifying of low boiling, low-freezing material.As rectifying of fluid products such as aromatic hydrocarbons, alcohols etc.But for the aromatic carboxylic acid series products, product as higher boilings such as trimellitic anhydride, pyromellitic acid dianhydride, high-solidification point, high-viscosity material, when under high vacuum condition, adopting above-mentioned rectifying device rectifying, because it adopts deep fat, coil pipe heating, phenomenons such as Flow of Goods and Materials is slow, heat exchange weak effect, blocking pipe can appear in material in rectifying device, material can produce side reactions such as decomposition, polymerization because of being in for a long time under the high temperature simultaneously, cause production not run well, the quality of product is affected, yield reduces.
Summary of the invention:
The purpose of this utility model provide a kind of be applicable to higher boiling, high-solidification point, high-viscosity material under high vacuum condition rectifying and can make material be evenly distributed therein, flow fast, heat-transfer effect is good, product yield is high rectifying still.
The purpose of this utility model realizes by following technical solution:
Rectifying still described in the utility model comprises cylindrical shell, external jacket, heat(ing) coil etc., on the upper surface of cylindrical shell, be provided with discharging opening, the liquid level gauge mouth, the visor mouth, sidewall is provided with charging aperture, the bottom is provided with slag-drip opening, temperature-measuring port, heat(ing) coil is stratiform and is coiled in the cylindrical shell, the deep fat that adds that is provided with heat(ing) coil in the sidewall or the bottom of cylindrical shell advances, outlet, be characterized in: be provided with a reductor at the top of cylindrical shell, be fixed with a shaft on the output shaft of reductor, the stirring axis hole that this shaft passes the cylindrical shell top stretches in the cylindrical shell near its bottom, on its axle head, be fixed with a stirrer paddle, outside stirrer paddle, be with a guide shell.
The another characteristics of above-mentioned rectifying still are: described stirrer paddle is pusher blade.
The utility model has the advantages that: pusher stirrer paddle is equipped with in (1) described rectifying still inside, and stirrer paddle is with guide shell outward, and it is quick, even to make the material quilt fully be heated evenly after the stirring, flow.(2) material can be by Fast Heating in this rectifying still, material after being heated stirs by pusher stirrer paddle, deliver to the liquid layer surface, because the static pressure on liquid layer surface is low, thermal material can be gasified, and the material after the gasification enters rectifying column, and the temperature of charge of gasification does not reduce simultaneously, stir circulation heating once more by pusher stirrer paddle.Therefore, material time of staying in this rectifying still shortens, and effectively reduces the generation of side reactions such as the decomposition of material under hot conditions, polymerization, has improved the gasification efficiency of rectifying still.(3) the utility model solved traditional rectifying device to the material that higher boiling, high-solidification point, high-viscosity material rectifying exist distribute, gasification is inhomogeneous, blocking pipe, material can make quality raising, the yield raising of product because of being in the problem that can produce side reactions such as decomposition, polymerization high temperature under for a long time simultaneously.(4) the utility model is suitable for the continuous rectification operation under high vacuum (absolute pressure 0-0.004Mpa) condition, helps the raising of labor productivity.
Description of drawings:
Fig. 1 is an agent structure schematic diagram of the present utility model.
The specific embodiment:
As shown in Figure 1, rectifying still described in the utility model comprises a cylindrical shell 2 and external jacket 3 thereof, is provided with discharging opening 1 on the upper surface of cylindrical shell 2, material is heated gasification in this rectifying still after, discharge from this discharging opening, import rectifying columns by the gas phase pipe 14 that joins with this discharging opening.Also be provided with liquid level gauge mouth and visor mouth 9 on the upper surface of cylindrical shell 2, sidewall is provided with charging aperture 10, the bottom is provided with slag-drip opening 15, temperature-measuring port 12, heat(ing) coil 4 is in the inner chamber that stratiform is coiled in cylindrical shell 2, and what be provided with heat(ing) coil 4 in the sidewall of cylindrical shell 2 or bottom adds hot oil inlet 13, and outlet 11.Be fixed with a reductor 8 at the top of cylindrical shell 2, be fixed with a shaft 5 on the output shaft of reductor 8, the stirring axis hole that this shaft 5 passes cylindrical shell 2 tops stretches in the cylindrical shell near its bottom, on its axle head, be fixed with a stirrer paddle 6, this stirrer paddle can adopt pusher blade, to improve stirring efficiency; Outside this stirrer paddle, also be with a guide shell 7.When this rectifying still work, material is by in charging aperture 10 these rectifying stills of input, and ON cycle adds deep fat, then adding deep fat imports in the rectifying still from adding hot oil inlet 13, reflux from exporting 11, and be coiled in heat(ing) coil 4 in cylindrical shell 2 inner chambers and carry out heat and conduct, material is heated by being stratiform; Simultaneously, open 6 pairs of materials of reductor 8 startup stirrer paddles and stir, because the effect of guide shell 7, material rolls mobile in this rectifying still up and down, fully heat absorption, and by quick, evenly gasification, the material after the gasification imports rectifying column from discharging opening 1.For different materials, by adjusting the rotating speed of reductor, can make material reach best gasification efficiency, improve the quality and the yield of product.
