Abstract
The invention provides an extraction method for extracting waste white clay residual oil and belongs to the technical field of utilization of waste white clay residual oil. The invention provides a method for effectively solving the recycling problem of the waste white clay residual oil. The technical scheme adopted by the invention is as follows: 1) adding a 6# extraction solvent utilized as an extract liquor and waste white clay into a self-made container at the mass ratio of (1-3):1, heating to 45-60 DEG C, stirring for 20-45 minutes, and then precipitating for 15-40 minutes to obtain mixed oil; and 2) adding the mixed oil into a separator, heating to 90-120 DEG C, and separating to obtain the recovered oil and solvent vapor. According to the invention, the extraction method is utilized to ensure that the content of the residual oil in the waste white clay is reduced to below 3-5%, an organic solvent used as the extraction solvent is used for extracting the residual oil in the white clay and the organic solvent is recycled so as to bring good economic benefit for an enterprise.
Description
Technical field
The useless carclazyte Residual oil method of extraction process extraction of the present invention belongs to useless carclazyte Residual oil and utilizes technical field.
Background technology
The operation that all has grease-decolor in each oily factory; Because of atlapulgite low price wide material sources are extensively adopted; And useless behind the grease-decolor waited until reason because of Processes and apparatus in should carclazyte and also has the Residual oil of 20-30%; Different because of there not being effective useless carclazyte Oil residue recuperation method to give up, cause immeasurable financial loss to enterprise.
Summary of the invention
Extraction process of the present invention extracts the method that useless carclazyte Residual oil provides the recycling problem of the useless carclazyte Residual oil of a kind of effective solution.
For solving the above problem, the technical scheme that the present invention adopts is for to carry out according to following steps:
The first step adopts soybean extracting solvent no.6 as extraction liquid, and extraction liquid and useless carclazyte weight part ratio are 1-3:1, join in the homemade container, heat to 45-60 ℃, stir 20-45min, precipitate 15-40min then, obtain mixing oil;
Second step added said mixing oil in the separator, was heated to 90-120 ℃ and separated, and obtained reclaiming grease and solvent gas.
Said solvent gas gets into the refrigerating unit recycling.
The beneficial effect that the present invention has is: the present invention utilizes extraction process can Residual oil in the carclazyte that give up be reduced to below the 3-5%, brings good economic benefits to enterprise.Extraction solvent extracts Residual oil in the useless carclazyte with organic solvent; Grease is dissolved in the organic solvent and becomes mixing oil like this; Get into separating device then and utilize grease to separate with the different of physico-chemical property of organic solvent, isolated organic solvent recycles.Residual solvent carries out heating recovery solvent wherein again and gets final product in the extractor.
