Abstract
The present invention discloses a kind of spiral runner membrane oil-water separator equipment. its runner is spiral one, and inside and outside of said runner are equipped with water-wet membrane and oil-wet membrane respectively. Said structure can greatly raise liquid permeability and pollution-resistant performance of membrane.
Description
The present invention relates to a kind of oily-water seperating equipment, is screw type film device at a kind of runner particularly, is applicable to separating of fluid that water-oil separating is different with other density.This equipment belongs to the technical field of pellicle separation equipment.
Spiral membrane module in the past, mainly be to be material liquid flowing channel with the straight channel, helical flow path is for seeing through the liquid runner, and it is material liquid flowing channel with the helical flow path that only a few is also arranged, and straight channel is for seeing through the liquid runner, but the action of centrifugal force of all not using helical flow path promotes separating substances; In addition, the film of existing spiral wound module all is with a kind of film, and separating property is all the same, and the difference of not considering the outside in the helical flow path is to the feed separation role.
Task of the present invention provides the improved film device of a class, and it is that centrifugation combines separating of the material that carries out different densities with film centrifugal action.
The invention provides 7 in accompanying drawing, wherein:
Fig. 1 helical flow path skeleton
Fig. 2 helical flow path membrane module core
Fig. 3 helical flow path membrane module
Fig. 4 straight channel skeleton
Fig. 5 ultrafiltration apparatus flow chart
The saturating liquid flux of Fig. 6 straight channel membrane module is change curve in time
The saturating liquid flux of Fig. 7 helical flow path membrane module is change curve in time
Below in conjunction with accompanying drawing embodiment film device of the present invention is done detailed explanation.
Embodiment 1
Consult Fig. 1-Fig. 7.Fig. 1 is the helical flow path skeleton, and [1] and [2] is respectively two material liquid flowing channel mouths of helical flow path, and [3] are the outlet of runner mouth [1], and [4] are the inlet of runner mouth [2].The skeleton rib is coated bonding agent on [5], and facing to the skeleton rib, the week that bonds is made helical flow path assembly core, as shown in Figure 2 the function of flat sheet membrane.The assembly core is contained in lucite shell or the ABS shell [6], and two ends are by termination [7] sealing, as shown in Figure 3.
The straight channel skeleton as shown in Figure 4, [8], [9] are the material liquid flowing channel mouth, [10], [11] the runner mouth for joining with [8] [9] respectively.The skeleton rib is coated bonding agent on [12], and facing to the skeleton rib, the week that bonds is made straight channel assembly core the function of flat sheet membrane.The assembly core is contained in lucite shell or the ABS shell, and two ends seal with the termination.Straight channel assembly (assembly 1) is contained in the ultrafiltration system, side by side with helical flow path assembly (assembly 2) as shown in Figure 5.Adopt the oil-water mixture of 20% water, 80% oil to carry out the ultrafiltration experiment as feed liquid.Result such as table 1, table 2 and Fig. 6, shown in Figure 7.Experimental result explanation helical flow path membrane module elementary membrane area water flux is much higher, and film pollute speed slowly many, only an oil-wet film that allows oil to pass through also can be bonded at the helical flow path inboard.
The characteristics of embodiment 2 present embodiments are, every group of diaphragm of spiral membrane module is to be made of with two kinds of different diaphragms of oleophylic hydrophilic, and hydrophilic diaphragm only allows water to see through, and does not allow oil to see through; And the diaphragm of oleophylic only allows oil to see through, and does not allow water to see through.Hydrophilic diaphragm is the outside at spiral, and the diaphragm of oleophylic is the inboard at spiral.Between two groups of diaphragms middle two groups of straight channel barriers that dividing plate is arranged, the parallel direction of reeling of barrier runner with film.Material liquid flowing channel is a helical flow path.Feed liquid when the helical flow path flow at high speed, because of centrifugal action, the accessible outer field hydrophilic diaphragm of water, and the internal layer diaphragm of oily accessible oleophylic, thereby two kinds of films all can keep high saturating liquid flux, and be difficult for contaminated.
