費用を要するものである。Regarding the degreasing treatment of the waste white clay which has adsorbed the oil content, the solvent extraction method of degreasing the adsorbed oil content with a solvent and discarding the residual sand, and the waste white clay containing the oil content are put into an incineration facility. Combustion methods such as roasting and burning oil and discarding residual sand have been used, but all of them require high processing costs.

無駄な処理費用がかけられている。As described above, the waste white clay on which oil has been adsorbed is collected by the oil and fat refining company and taken to the waste disposal company, and the waste disposal company costs the degreasing treatment. However, it is extremely expensive to dispose of the waste.

現状である。On the other hand, since water-repellent cement is composed of a metallic soap component, refined fats and oils are purposely mixed into the cement for refining, and the activated clay as an adsorbent for refining fats and oils is made of montmorillonite clay as a raw material. Since calcium-based cement is also used as an admixture, waste clay that has adsorbed oil for the decolorization treatment of oils and fats is processed at high cost, and refined oils and fats are treated. The current situation is that there is a contradiction that it is mixed with cement again.

である。Means for Solving the Problems In the decolorizing step of refining oils and fats, the present invention is directed to a waste white clay which is put into deoxidized crude oil in a deoxidized process and passed through a refining pipe together with the crude oil to be collected on a filter cloth. By using it as a cement admixture as it is, it is possible to treat waste clay itself and to refine water-repellent cement without admixing refined fats and oils.

In the general oil and fat refining process, stirring and filtering are repeated while adding additives and adsorbents to crude oil through a purifying pipe from a stirring hopper to a filtering device.First, phosphoric acid is added to crude oil and caustic soda is added. Frees gums and removes fatty acids.

At this stage, the clay becomes waste clay, which is filtered off on the filter cloth set in the filtering device and collected in the form of cake. It The waste clay at this stage has been conventionally requested to be collected by a waste company.

In the heating step, fiber chips and the like are mixed as an extender, put into a sizing board form, and board-formed. If it is dried by heating, the waste treatment process directly becomes the manufacturing process of the water repellent board, which is extremely efficient.
