Abstract
一种液—液萃取膜分离设备，属于一种化工萃取设备。由混合搅拌萃取室与两个分相室组成，两分相室为水相分相室与有机相分相室。分相室内有若干个分相膜固定支架，从而起到了增加分相膜的面积，提高分相能力，减小设备体积的作用。
A liquid-liquid extraction membrane separation device belongs to chemical extraction equipment. It consists of a mixing and stirring extraction chamber and two phase separation chambers, the two phase separation chambers are an aqueous phase separation chamber and an organic phase separation chamber. There are several phase-separation membrane fixing brackets in the phase-separation chamber, which can increase the area of the phase-separation membrane, improve the phase-separation ability, and reduce the volume of the equipment.
Description
The utility model belongs to a kind of chemical industry extraction equipment.
The utility model can be used to carry out liquid-liquid extraction to be separated.Extraction and stripping apparatus commonly used both at home and abroad has: mixer-settler, column extractor centrifugal extractor.With the mixer-settler is example: it is made up of mixing section and phase separation chamber.Its operational condition requires the biphase density difference more than 0.1, and it has the big shortcoming of floor space.
The purpose of this utility model is in order to provide a kind of to density difference very little or density equate the liquid-liquid extraction separating device of water with organic phase.
The utility model carries out chemical treatment with porous membrane and makes hydrophilic phase membrane.Treatment process is: polyvinyl alcohol with sulfuric acid and formaldehyde dissolving, is evenly spread upon its solution on the nylon nonwoven fabrics water flushing then.Handle with another kind of porous membrane again and make hydrophobic membrane.Treatment process is: soak polypropylene non-woven fabric with kerosene.When two kinds of phase membranes of profit mixed liquor and this contacted, because the difference of the physico-chemical property of its contact surface, hydrophilic film only allowed water pass through, and hydrophobic membrane only allows oil phase pass through.When oil phase and water are separated, also finished the liquid-liquid extraction process.
Principle schematic such as Fig. 1 of film phase-splitting extraction equipment, wherein 14 for mixing the stirring extraction cell, and 3 is the water phase separation chamber, and 9 is the organic phase phase separation chamber.
Mixing the stirring extraction cell has a rotatable stirring arm, and in 15 places and main equipment sealing.
The phase separation chamber internal arrangement several fixed supports that is surrounded by phase membrane.Technical process as shown in Figure 1.When organic phase and water density have difference, gently be organic phase mutually for example, heavy phase is a water, and then organic phase is from import 6, and water enters respectively to mix from import 1 and stirs extraction cell, and under the effect of stirring arm, the counter-current extraction process is finished in the contact of two-phase thorough mixing; Organic phase enters organic phase phase separation chamber 3 by water outlet 2 then, and isolates partly organic phase by hydrophobic membrane, and this organic phase is discharged by the outlet 4 of phase separation chamber and entered next stage; The mixture of remaining most organic phase and water still turns back to water-in 5.In contrast, water is entered to mix by water-in 1 and stirs extraction cell, and enter water phase separation chamber 9 by water outlet 7, partly water is told by water outlet 8 discharges by hydrophilic film and is entered next stage, the mixture of remaining most water and organic phase still turns back to water-in 10, so just finishes the counter-current extraction process.If biphase density is equal fully, so, the import of two kinds of feed liquids is decided according to practical situation.
Fig. 2: mix to stir the structure iron of extraction cell, the blade up and down 11 of stirring arm is greater than other blade, and faces water outlet 2 and 7.
Fig. 3: the structure iron of phase separation chamber, the film fixed support of phase separation chamber are shaped as frame structures, one side frame has several little water outlets 13.When phase membrane wraps on the support, just formed an enclosed space except that little water outlet 13.When organic phase contacted with phase membrane with the mixture of water, organic phase and the water told by phase membrane just flowed out from little water outlet 13.
Embodiment 1:
F with load in three grades of series connection of sulfuric acid back extraction organic phase 5709 of 6N
3+ e, water and organic phase volume ratio are 1:1 in mixing section, mixing speed under 250 rev/mins of conditions, F in the organic phase
3+ eBack extraction ratio reach 92%.
