Abstract
The utility model provides a device capable of recycling dimethyl benzene in waste solvent oil. The device comprises a rectifying tower, a tower kettle, a heating device, a condensation device, a reflux ratio controller and a product receiver, wherein the tower kettle is connected and communicated with the bottom of the rectifying tower; the heating device is arranged below the tower kettle; the condensation device is connected and communicated with the top of the rectifying tower; a thermocouple is also arranged at the top of the rectifying tower; and a residual liquid receiver is arranged on the side edge of the heating device. The device provided by the utility model has the advantages of low treatment cost and secondary pollution prevention.
Description
Technical field
The utility model relates to the retracting device of active ingredient in a kind of waste liquid, reclaims the device of xylenes in a kind of specifically waste solvent oil.
Background technology
Solvent naphtha is one of five big types of oil products.The purposes of solvent naphtha very extensively.The first-elected paint solvent oil (being commonly called as paint naphtha) that consumption is maximum, next has edible oil, printing-ink, leather, agricultural chemicals, pesticide, rubber, cosmetics, spices, medicine, electronic unit equal solvent oil.And in automobile, paint and mechanical processing industry, also can produce the waste solvent oil that is rich in xylenes in a large number.Contain in this waste solvent oil multiple organic impurities and complicated component, viscosity big, penetrating odor is arranged, endanger huge to nerve system of human body and ecological environment.The method of processing waste solvent oil commonly used has dilution method, burning method and distillation under vacuum etc. at present, but these methods all consume energy greatly, and can cause secondary pollution to environment.
Summary of the invention
The purpose of the utility model is that a kind of disposal cost is low in order to provide, reclaim the device of xylenes in the waste solvent oil of non-secondary pollution.
The technical scheme of the utility model is: the device that reclaims xylenes in a kind of waste solvent oil; Comprise rectifying column, tower still, heater, condensing unit, reflux ratio controller and product receiver; The tower still links to each other with rectifier bottoms and communicates; Heater is positioned under the tower still, and condensing unit links to each other with the rectifying column top and communicates; Also be provided with thermocouple at the rectifying column top, the heater side also is provided with surplus liquid receiver.
Reclaim the device of xylenes in a kind of waste solvent oil; Its operating process is following: waste solvent oil is put into the tower still; Open condensed water, connect heating power supply the tower still is heated, when liquid comes to life in the band tower still heating voltage is turned down; When cat head has steam to occur and begin to have liquid to reflux, keep infinite reflux state 30-50min.Note the temperature of tower still, cat head, epimere and the hypomere of this moment.Regulate reflux ratio controller, it is 10 that reflux ratio is set, and the extraction time is that the cut of 3-5min is xylenes.
Advantage and the good effect that the utlity model has are:
The device that reclaims xylenes in the waste solvent oil of the utility model possesses that disposal cost is low, the advantage of non-secondary pollution.
