摘要:
An apparatus and method of high pressure treatment of bulk material by extraction and/or impregnation may involve treating bulk material in an internal volume of a pressure vessel apparatus at a high pressure level in a range from 40 to 1000 bar under isolation from the environment. The high pressure treatment may be performed charge-wise in a closed system in the pressure vessel apparatus in that the bulk material is supplied charge-wise to the internal volume with the pressure vessel apparatus closed and is positioned in at least one treatment plane. Upon completion of the high pressure treatment, the bulk material is discharged charge-wise from the internal volume with the pressure vessel apparatus closed. This also gives advantages in terms of handling, especially also with regard to material flow, and with regard to operational reliability.

An apparatus and a method is for separating liquid from a material comprising a solid fraction and a liquid fraction. The apparatus has a conveyor belt for bringing the material from a receiving portion to a discharge portion. At least a portion of the conveyor belt is provided with at least one sorption means for absorbing and/or adsorbing liquid from the material while the material is carried between the receiving portion and the discharge portion.

Method for separating a polishing material, which is capable of separating and recovering cerium oxide from a used polishing material that is mainly composed of cerium oxide and a regenerated polishing material which can be obtained by the separation method. This method for separating a polishing material is characterized in that a divalent alkaline earth metal salt is added into the slurry of the used polishing material, while controlling the temperature of the slurry within the range of 10-70 DEG C., thereby causing the polishing material to aggregate under such conditions that the mother liquor has a pH of less than 10.0 as the pH is converted to one at 25 DEG C. so that the polishing material is separated from the mother liquor.

An extraction apparatus capable of continuously and efficiently extracting a biological substance is provided. Multiple rotation discs are utilized in the extraction apparatus to significantly improve the efficiency of extracting the biological substance by using an extraction solvent. Specifically, when the extraction solvent is applied to extract lipids from microalgae, retention time of the microalgae in the extraction solvent can be significantly increased, and solubility of the microalgal lipids in the extraction solvent can be improved. Hence, the efficiency of extracting the lipids from the microalgae by using the extraction solvent can be enhanced. On the other hand, owing to the improvement of the efficiency of extracting the lipids from the microalgae, the amount of the extraction solvent can be reduced, and production costs can be reduced as well.

Apparatus for separating or extracting liquid phase substances from gel phase substances in a semisolid mobile cellular system wherein there exists a substantial difference in density between the liquid and gel phase substances of the system. The apparatus is particularly useful for separating or deliquoring black liquor soap substances manufactured in a chemical pulping operation. The apparatus, in a preferred form, includes a long tall cylindrical vessel or tank, a vertical rotor mounted on the vertical center axis of the tank interior having a series of press rods radially fixed cantilever fashion on the rotor shaft and projecting toward the cylindrical interior tank wall, a second series of press rods generally cantilever fixed to the tank wall interior and projecting radially toward the rotor axis and alternatingly arranged with the movable radially extending rotor press rods. The semisolid cellular soap substance or the like is pumped into the tank and the rotor driven at a slow speed (3-5 r.p.m.) to cause the cellular substance to be squeezed between the alternatingly arranged fixed and movable press rods. This causes the liquid phase substance to collect on the trailing side of each of the press rods and the liquid to be conducted to a liquid pool formed either at the upper or lower elevation of the tank depending on whether the liquid phase substance is heavier or lighter than the gel phase substance in the semisolid cellular system being processed.

In order to remove a component from solid particle material by extraction, use is made of a column with one or more tubes which extend between the ends of the column, at least one filter being fitted in the wall of each tube. The particle material is fed in at a first end of the column and, forced by hydraulic pressure, moves along the abovementioned tubes to scraping means fitted at the second end of the column. Extraction liquid is fed into the column at the abovementioned second end and flows in countercurrent to the particle material in the direction of the abovementioned first end of the column. Extraction liquid with component from the particle material dissolved in said extraction liquid passes by way of the above mentioned filters into the abovementioned tubes and flows in countercurrent to the particle material to an outlet at the abovementioned first end. The particle material is scraped off at the abovementioned second end by the scraping means.

摘要:
In the process for discharging solids treated with liquids from vertical columns, the treated solids are transported by means of a conveyor to a circulating auxiliary liquid with variable hydrostatic pressure and from there to the subsequent stage of treatment. By varying the hydrostatic pressure of the cycle of auxiliary liquid, the pressure conditions in the system can be adjusted in a manner to permit discharging from the column pure solid or solid with a defined amount of adhering liquid, or introducing defined amounts of liquid from the auxiliary cycle into the column in countercurrent flow with respect to the direction of flow of the solid.
