Description
Technical field
The invention belongs to membrane filtration technique field, be specifically related to a kind of high pressure resistant separating and filtering film column device with low-resistance flow guiding disc.
Background technology
Dish periosteum assembly (Fig. 1) is the much progress in plate film assembly technical field.This membrane module is a kind of device utilizing nanofiltration or reverse osmosis to filter liquid and separate.Owing to there being the diversion member of hydrodynamic performance excellence in this device, when fluid within it flows, having runner width, flow process is short, the feature of full turbulent flow.These features all make dish periosteum assembly compare other membrane modules to have resistance resistant to pollution characteristic little, high.In the case of reverse osmosis turbidity and sludge density index (SDI) (SDI) increase, it also can run cost-effectively.The most it is successfully applied in the processing procedure of percolate.This device mainly has and includes glass fiber reinforced plastic round pipe bearing shell, the screwed draw-in bar in two ends being positioned on bearing shell axis, and 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 one piece of middle folder produces water filter layer, and periphery is sealed to form (Fig. 3 dash area is ultra-sonic welded region) by ultra-sonic welded.The flow guiding disc being enclosed within center pull rod and the membrane stack of diaphragm composition, connected farad by flange in the bottom, terminal and nut jointly act on fastening and compresses.Fluid (indicated by an arrow on Fig. 1) in pressure vessel is sealed by the lip-type packing at flange in the bottom and terminal adpting flange and prevents from revealing.
Such as Fig. 1 and 2, fluid enters putamina from former water inlet, in the space that the slit flow between putamina and membrane stack to 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, it is obstructed at the flange of flow guiding disc and turns back, flow through the another side of membrane layer, leave from the pod apertures of next stage flow guiding disc, in the way of the most cranky, flow through the whole membrane stack mode of membrane stack (fluid shown in Fig. 1 arrow flow through).The water that produces through diaphragm collects in the product water at flow guiding disc center and collects in guiding gutter, separated with dense water by O RunddichtringO about, flow into and produce in water flow passage, along center pull rod, finally from producing water out discharge, dense water collects in the space of terminal adpting flange and the formation of end flow guiding disc, dense water out discharge.

2, when fluid flows through flow guiding disc, flowing to and leave the pod apertures at flow guiding disc center, this makes the O RunddichtringO adjoined with pod apertures bear from the impulsive force in the range of 360 degree, is very easy to be subjected to displacement.O herein is once subjected to displacement, and the filter effect of equipment just lost efficacy.And the O finding and repairing displacement is the work taken time and effort very much, has had a strong impact on practicality and the marketing of dish periosteum assembly in actual use.
3, fluid often will produce twice baffling through one piece of flow guiding disc at the flange of flow guiding disc, produces bigger drag losses.The drag losses causing whole equipment is relatively big, makes to have to be increased to higher pressure into water, thus increases the burden to whole equipment, be degrading situation about including described by shortcoming 1 and 2.And due to the hypertonia of water inlet, frequently result in water inlet connecting line leakage, affect the properly functioning of work.
4, the top of the water conservancy diversion salient point on flow guiding disc is a bit, with the contact area of diaphragm in theory close to zero.But under actual high-voltage operates, due to the elasticity of diaphragm macromolecular material itself, diaphragm always has slight movement.This allows for the membrane surface with water conservancy diversion salient point top contact by lasting mechanical wear, leaves the deep marking to diaphragm to such an extent as to pierces through diaphragm, causes whole equipment filter effect to lose efficacy.When operating temperature and improving, the risk that this reason causes diaphragm to be pierced is bigger.
