Description
Technical field
The invention belongs to membrane filtration technique field, be specifically related to a kind of low-resistance flow guiding disc and high pressure resistant isolated filter membrane column device.
Background technology
Dish periosteum assembly (Fig. 1) is the much progress in plate film assembly technical field.This membrane module a kind ofly utilizes nanofiltration or counter-infiltration to filter and the device be separated liquid.Owing to there being the diversion member of hydrodynamic performance excellence in this device, when fluid flows, have runner wide within it, flow process is short, the feature of full turbulent flow.These features all make dish periosteum assembly compare other membrane modules to have little, the high resistant to pollution characteristic of resistance.When counter-infiltration turbidity and sludge density index (SDI) (SDI) increase, it also can run cost-effectively.It is successfully applied in the processing procedure of percolate abroad.This device mainly contains and comprises glass fiber reinforced plastic round pipe bearing shell, and be positioned at the screwed draw-in bar in two ends on bearing shell axis, flow guiding disc and diaphragm are alternately enclosed within center pull rod, and diaphragm is clipped in the middle of two flow guiding discs.Diaphragm is the semipermeable membrane of two similar laser disc shapes, and therebetween one piece produces water filter layer, and periphery is sealed to form (Fig. 3 dash area is ultra-sonic welded region) by ultra-sonic welded.Be enclosed within the membrane stack of flow guiding disc in center pull rod and diaphragm composition, connect farad and the fastening compression of nut acting in conjunction by flange in the bottom, terminal.Fluid (Fig. 1 represents with arrow) in pressure vessel prevents from revealing by the lip-type packing sealing at flange in the bottom and terminal adpting flange place.
As Fig. 1 and 2, fluid enters putamina from former water inlet, from the slit flow between putamina and membrane stack in the space that flange in the bottom and end flow guiding disc are formed, pod apertures in the middle of flow guiding disc flows to the another side of flow guiding disc, one side along membrane layer flows to the flange of flow guiding disc periphery, be obstructed at the flange place of flow guiding disc and turn back, flow through the another side of membrane layer, leave from the pod apertures of next stage flow guiding disc, flow through whole membrane stack (shown in Fig. 1 arrow, fluid flows through the mode of membrane stack) in mode cranky like this.The product water that product water through diaphragm collects in flow guiding disc center is collected in guiding gutter, separated with dense water by the O RunddichtringO around it, flow into and produce in water flow passage, along center pull rod, finally discharge from product water out, dense water collects in the space of terminal adpting flange and the formation of end flow guiding disc, is discharged by dense water out.
Dish periosteum assembly is mainly used in the zero discharge of industrial waste water field of high concentration, high salinity, as unmanageable waste water such as petroleum asphaltene, coal chemical industrial waste water, wastewaters of steel industry.Process these hc effluents, require that dish periosteum assembly works (being at least greater than 70bar) at a very high pressure.In the process of practical application, existing dish periosteum assembly has the following disadvantages:
