Abstract
The present invention relates to a Sonne's extraction method in industry. After material is added in a soaking kettle, a solvent which comes from a condenser is continuously added in the soaking kettle; after a certain liquid level is achieved, the solution continuously flows into a dikettleer, the solution is evaporated and concentrated, and the evaporated solvent enters the soaking kettle to be circularly used after being condensed. After the extraction requirement is achieved, solution carries out solid-liquid separation through a Buchner funnel, the extracted solid constituent is prepared after being evaporated to dryness, and the part which is not dissolved is mechanically separated. The present invention can be used for the continuous production in industry.
Description
The invention belongs to the soluble part in the solid material with the method that solvent extraction comes out, be specifically related to a kind of extraction process for industrial solid material.
GB2292-80 introduces a kind of " coal tar pitch methyl alcohol insoluble matter assay method (extraction process) ", adopt fatty extractor, the filtration paper cylinder that sample is housed of known weight is put into the extraction tube of fatty extractor, the fat extraction device heats on sand is molten, go out DDGS in the coal tar pitch with the toluene extracting, residue is an insoluble matter.The solvent extraction that this method principle is used for the solid material DDGS is feasible, but the assay determination that can only be used to test can not be used for industrial production.
The objective of the invention is to develop a kind of continuous industrial solid material extraction process that can be used for.
The object of the present invention is achieved like this: the solid material that adds a certain amount of certain particle size in soaking still, constantly add corresponding solvent, when the solution of a certain component of extracting material reaches the certain liquid height, control valve is opened, this solution is constantly put into distillation still, after this solution is heated in distillation still, the solution that contains corresponding solid constituent is concentrated along with constantly steaming of solvent, return again after the solvent condenses that steams and soak the respective components that still is used for the extracting solid material once more, after reaching the extracting requirement solid material and extract are put into the Buchner funnel isolated by filtration, solvent evaporation in the solution after will concentrating again is clean, so that obtain wanting in the solid material respective components of extracting.
The embodiments of the invention accompanying drawings is as follows:
Fig. 1 is a schematic flow sheet of the present invention.
As shown in the figure, the 1st, soak still, the 2nd, liquid level control probe, the 3rd, driver, the 4th, filter, the 5th, fluid level control valve, the 6th, Buchner funnel, the 7th, blowdown valve, the 8th, distillation still, the 9th, tapping valve, the 10th, the raffinate storage tank, 11 is the solvent vapour conduit, the 12nd, residual cake valve, the 13rd, condenser.
The running of the inventive method is as follows: put into by the material of extracting and solvent in soaking still 1, add thermal still 8, solvent vapo(u)r through conduit 11 to condenser 13, condensed solvent constantly adds still 1, when wherein liquid to 2 places of popping one's head in through driver 3, open interstage valve 5, the solution that contains material component constantly flows into distillation still 8.After reaching the extracting requirement, open blowdown valve 7, material is passed through Buchner funnel 6 successively, distillation still 8 and residual liquid tank 9 carry out Separation of Solid and Liquid in Buchner funnel 6, will obtain wanting the component of extracting behind the solvent evaporate to dryness in the raffinate in distillation still.
Obviously, this method can be used for industrial continuous production.
