Description
Technical field
The present invention relates to the coiled reverse osmosis membrane assembly.
Background technology
The coiled reverse osmosis membrane assembly of known technology is that the water purification diaphragm group that consists of former water flow-guiding screen, tabular reverse osmosis membrane and the stack of product water flow-guiding screen is wrapped on the water producing pipe of center and forms; Wherein tabular reverse osmosis membrane is folded, in the former water flow passage formed between the inner surface of former water flow-guiding screen after tabular reverse osmosis membrane is folding, in the product water flow passage formed between the outer surface of product water flow-guiding screen after tabular reverse osmosis membrane is folding; Produce water flow passage in the side openings of being close to the center water producing pipe, remaining three side is bonded and sealed with glue; Water purification diaphragm group is after the water producing pipe of the center of winding, and whole outer surface is wound around sealing with adhesive tape.During the rolled membrane module operation, former water flows into from an end of membrane module, passes former water flow passage along the axial of membrane module, then flows out from the other end of membrane module, and the water of outflow is condensed water; Current are in passing the process of former water flow passage, and a part of water sees through reverse osmosis membrane and flows in the product water flow passage, with the direction that is wound around the center water producing pipe, in the product water flow passage, flow to the center water producing pipe, finally from an end of center water producing pipe, flow out.
The weak point of above-mentioned known technology is: the axial length that the length of former water flow passage is the coiled reverse osmosis membrane assembly, the width of former water flow passage is along the length on the limit of winding direction after water purification diaphragm group is launched, the width of common former water flow passage significantly is greater than the length of former water flow passage, makes:
1. the flow velocity of former water in former water flow passage is very slow;
2. the flow velocity along the former water of former water flow direction flows slower and slower.Reason is that the cross-sectional area of former water flow passage is uniformly on whole runner, and the flow of former water is to flow less and less, because there are the part current constantly to see through the event of reverse osmosis membrane.
Because the flow velocity of former water in former water flow passage is too slow, cause in former water easily stopping up the material (such as colloid etc.) of reverse osmosis membrane easily in reverse osmosis membrane surface deposition or fouling, stop up reverse osmosis membrane, make the salt rejection rate of reverse osmosis membrane and aquifer yield low, shorten service life.In order to improve the service life of counter-infiltration, must improve the former water flow velocity of counter-infiltration pleurodiaphragmatic in terspace water side, this just causes the condensed water flow of discharge too large, waste water resource.
Deficiency in view of above-mentioned known technology, the patent documentation that application number is 200910201739.8 discloses the technical scheme of above-mentioned known technology being carried out to improved, in this technical scheme, former water flow passage is arranged to: the dual-side adjacent with folded edge of former water flow passage, away from the part section closing seam of center water producing pipe, makes this dual-side approach water producing pipe place, center and forms respectively the segment raw water inlet and make the side relative with folded edge of water inlet flow channel form the condensed water delivery port.Like this, just significantly improve the flow velocity of former water in former water flow passage, received good effect.
But, it is uniform that the cross-sectional area of the former water flow passage in this technical scheme remains on the length direction of whole former water flow passage, can not adapt to raw water flow in the characteristic reduced gradually along water (flow) direction, the deficiency that still exists the flow velocity along the former water of former water flow direction to flow slower and slower.
