摘要： PURPOSE:To elevate separation performance removing adverse effect due to the flow of a dispersion liquid, by providing two grooves along the length of an electrophoretic layer to mount an outlet nozzle at each of demarcated chambers which are formed by demarcating the grooves. CONSTITUTION:A lamellar electrophoretic layer 2 is provided horizontally and two grooves 3 are provided at the bottom of the body 1. The grooves 3 are demarcated by a plurality of weir 12 and an outlet nozzle 4 is provided at the bottom of each f the demarcated chambers. Then, a dispersion liquid is fed into the electrophoretic layer 2 from an inlet nozzle 8 and is electrically migrated with electrode chambers 5 on both sides thereof. The dispersion liquid flows through electrophoretic layer 2, moving as shown by the dotted line 13 and drops to the bottom of the grooves 3 and the dispersion liquid entering the demarcated chambers is withdrawn from the outlet nozzle 4. The dispersion liquid kept from entering the grooves 3 is allowed to flow out of an outlet nozzle 11. Thus, as the grooves provided on the electrophoretic layer are demarcated to withdraw the dispersion liquid, effect due to turbulence in the flow thereof can be eliminated to elevate the separation performance.
摘要翻译：目的：提高分离效果，消除由于分散液的流动引起的不利影响，通过沿着电泳层的长度设置两个凹槽，以便在通过划定凹槽形成的每个分隔室上安装出口喷嘴。构成：水平地设置层状电泳层2，在本体1的底部设置有两个槽3.槽3由多个堰12划分，出口喷嘴4设置在每个f的划分的底部房间。然后，将分散液从入口喷嘴8供给到电泳层2中，并在其两侧的电极室5中电迁移。分散液体流过电泳层2，如虚线13所示移动，并下降到槽3的底部，并且进入分界室的分散液体从出口喷嘴4排出。分散液保持不进入槽允许从出口喷嘴11流出。因此，由于设置在电泳层上的凹槽被划分以抽出分散液，可以消除由于其流动中的紊流引起的影响，从而提高分离性能。

摘要： PURPOSE:To improve back extraction rate considerably by using a centrifugal extractor for a back extractor, and an aq. ammonium carbonate for back extracting liq., and regulating the temps. of an org. solvent and the aq. ammonium carbonate soln. to specific temps. or above. CONSTITUTION:In the neighborhood of the outside circumference of a rotating body 2 under high speed revolution around the axial center of a revolving shaft 1, an org. solvent wherein amine type chemicals are dissolved in a diluting agent such as kerosene extracted with uranium is heated to about >=40 deg.C and is introduced on the outside circumferential side of the body 2 through an introduction passage 3, and an aq. ammonium carbonate soln. heated to the same temp. is introduced to the inside circumferential side of the body 2 through a back extracting liq. introducing passage 4. In the body 2, the continuous layer 6a on the org.solvent side is formed on the inside circumferential side of the body 2 with a main interface as a boundary and the continuous layer 6b of the aq. ammonium carbonate layer is formed on the outside circumferential side on account of a difference in specific gravity. The respective dispersed liquid drops 7a, 7b flow to the continuous layers 6a, b facing each other and collide against each other at the main interface 5, by which back extraction is progressed. The aq. ammonium carbonate wherein uranium is extracted is discharged through a discharge port 9.

摘要： PURPOSE:To economically separate oil from water by a method wherein oil is added with an emulsion breaker and guided into a centrifugal separator through a spiral pipe which will cause oil to make a circular motion in a plane perpendicular to oil flow direction. CONSTITUTION:Oil which contains water 5 is added with an about 10-100ppm emulsion breaker 8 and is passed through pump 5 into a spiral pipe 3 which causes the oil to make a circular motion in a plane perpendicular to its flow direction, then the oil is guided into centrifugal separator 1. The process accelerates unification of small water droplets in oil so that the separator 1 enables to economically separate water 7 and oil 6.

摘要： PURPOSE:To recover heat and reduce the volume of residue, by reusing water, recovered from a combination of desalination equipment for fuel oil with the recovery and purification of separated water, for desalination, and by incinerating the sludge from the equipment. CONSTITUTION:The oil content of the heavy oil 6 separated from the sludge separator 1 is recovered by the oil separator 23 as the oil 24, and mixed with the salt- containing water 15 from the desalination equipment 2. The mixture is fed to the evaporator 17, and the steam 20 gives heat to the fuel oil 5 in the heat exchanger 21, is condensed into the condensed water 22, stored in the clean water tank 11, and mixed with the desludged oil 7. The residue 19 dehydrated in the evaporator 17 is fed by the pump 26 to the incinerator 27 to burn combustibles. The heating medium 18 circulated by the pump 25 is thus heated to reduce the volume of the residue 28, which is taken out of the furnace bottom 27.

摘要： PURPOSE:To increase the extraction efficiency, by attaching a ring member inside the rotating body, being inclined with respect to the axis, by providing a clearance to a member adjoining in the axial direction. CONSTITUTION:A heavy liquid is introduced into each partitioned chamber in the central part in a rotating body 2 through a heavy liquid lead-in pipe 14, and a light liquid is introduced into each partitioned chamber through a light liquid lead-in pipe 15. The heavy liquid runs in the axial direction in each partitioned chamber along the slope of an inclined cylinder 16, and passes through a clearance 19 provided in the circumferential direction to run in the outer circumferential direction, and is taken out from a heavy liquid lead-out passage 6 through passage 6a from the peripheral part of the rotating body 2. The light liquid, on the other hand, runs in the axial direction along the slope of the inclined cylinder 16 similarly as in the case of heavy liquid, towards the central direction in each partitioned chamber, and is caused to counter-contact with the heavy liquid running in the outer circumferential direction along the clearance 19, and taken out from a light liquid take-out passage 7 through a passage 7a from the central part of the rotating body 2. By repeating the joining and dispersion of heavy liquid and light liquid between V-rings and side walls, the extraction efficiency is increased.

摘要： PURPOSE: To desalt raw oil or heavy oil easily, charging a centrifugal extractor with a mixt. of raw material oil and water having been used for washing the oil as the light liq., and a small amount of fresh water as the heavy liq. in order to make both the liqs. contact with each other countercurrently.
CONSTITUTION: Raw material oil 1 is mixed with salt-contg. recycle water 20 having been used for washing, and the mixt. is heated in a preheater 19 to 40W 80°C, and is introduced through a mixing value 18 to a liq./liq. countercurrent centrifugal extractor 17 by way of a light liq. inlet side (the outer periphery side of the rotor). Simultaneously, fresh water 9 in an amount 1W5% based on the raw material oil is charged through a heavy liq. inlet side (the inner periphery of the rotor). The oil admitted from the light liq. side is separated from water at the outer periphery of the rotor and flows into the inner periphery side, and is washed with fresh water 9 admitted from heavy liq. side, it is then discharged as desalted oil 12'. Hereby, by use of only one centrifugal extractor, the salt content is decreased to 0.5 ppm at relatively low temp., without use of an emulsion breaker.
