The multi-layer reverse osmosis membrane and diversion net; the central tube and the two ends of the shell are connected by connectors. When in use, the raw water enters the reverse osmosis filter element from one end of the reverse osmosis filter element. Under the action of pressure, part of the water passes through the reverse osmosis membrane to form water with a lower concentration. After entering the central tube, it flows out from one or both ends of the central tube. This part of the water It can be called produced water or pure water; the other part flows out from the other end of the shell, which can be called waste water or concentrated water. In this kind of reverse osmosis membrane element in the prior art, after the raw water is treated, a large part is discharged as waste water, and only a small part becomes pure water. The proportion is relatively small, and the raw water recovery rate is low, resulting in the waste of raw water.

The water passage holes of the water inlet chamber and the water outlet chamber, when the waste water valve 410 closes the valve port, the water in the water inlet chamber flows into the water outlet chamber through the water passage hole, and the water outlet chamber The diameter of the through hole is 0.4-0.7mm.
本实用新型的反渗透净水系统的反渗透滤芯200中，原水通过侧流进水流入反渗透膜元件220，相较于传统的反渗透滤芯200而言，原水的流道变窄，进水面积减小，而流程也大大增长，因此可以增加原水与反渗透膜片接触的时间，提高反渗透净水系统的原水回收率；因为减小了原水进水面积，可以加大反渗透膜片组的渗透膜片表面水流速度(在进水通量一定时，进水通量Q与水流速度V之间的关系是V＝Q/S；其中，S为进水面积，具体的，S＝Ld；L为进水端膜片长度，d为截面厚度，侧流主要是减小了L，另外可以使用小的进水导流网减小厚度d)，因而能够减小反渗透膜片表面浓差极化，降低该反渗透膜元件220的污染速度，有利于提高反渗透膜元件220的使用寿命；同时，由于侧流进水的反渗透滤芯200净水能力较强，因此可以设置所述废水阀410的过水通孔的孔径较小，从而在整个系统运行过程中有效降低废水流速，增加原水与反渗透膜元件220的接触时长，对原水进行充分净化，进一步提高原水回收率，从而改善原水的浪费问题，达到节约原水的效果。In the reverse osmosis filter element 200 of the reverse osmosis water purification system of the present utility model, the raw water flows into the reverse osmosis membrane element 220 through the side flow inlet water. Compared with the traditional reverse osmosis filter element 200, the flow path of the raw water becomes narrower, and The area is reduced, and the process is greatly increased, so the contact time between the raw water and the reverse osmosis membrane can be increased, and the raw water recovery rate of the reverse osmosis water purification system can be improved; because the raw water inlet area is reduced, the reverse osmosis membrane can be enlarged The water flow velocity on the surface of the permeable membrane of the group (when the water inlet flux is constant, the relationship between the water inlet flux Q and the water flow velocity V is V=Q/S; wherein, S is the water inlet area, specifically, S= Ld; L is the length of the diaphragm at the water inlet, and d is the thickness of the section. The side flow mainly reduces L. In addition, a small water inlet diversion net can be used to reduce the thickness d), thus reducing the surface of the reverse osmosis diaphragm. Concentration polarization reduces the pollution rate of the reverse osmosis membrane element 220, which is beneficial to improve the service life of the reverse osmosis membrane element 220; at the same time, because the reverse osmosis filter element 200 with side flow water has a strong water purification ability, it can be set The pore diameter of the water passing hole of the waste water valve 410 is small, thereby effectively reducing the waste water flow rate during the operation of the whole system, increasing the contact time between the raw water and the reverse osmosis membrane element 220, fully purifying the raw water, and further improving the raw water recovery rate. Thereby improving the waste of raw water and achieving the effect of saving raw water.
在本实用新型的反渗透净水系统中，废水阀410的过水通孔的孔径越小，则废水的流速越低，例如，在0.42MPA(反渗透净水系统常用一种的渗透压力值)的压力的作用下；当所述废水阀410的过水通孔的孔径为0.4mm时，可以废水的流速为200mL/min左右；当所述废水阀410的过水通孔的孔径为0.7mm时，废水的流速为650mL/min左右；因此通过限定孔径即可限定废水流速。过水通孔的具体尺寸需要根据反渗透滤芯200的净水能力进行选取，反渗透滤芯200的净水能力较高时，可以设置过水通孔的孔径较小。该废水阀410可以为常闭式直动电磁阀，平时使用时，废水阀410的阀口保持关闭状态，当需要清洗反渗透净水系统时，废水阀410通电打开阀口，为废水提供较宽的流道，以供大量水快速流过，从而达到较好的冲洗反渗透净水系统的目的。In the reverse osmosis water purification system of the present utility model, the smaller the aperture of the water passing hole of the waste water valve 410 is, the lower the flow rate of the waste water is, for example, at 0.42MPA (a kind of osmotic pressure value commonly used in reverse osmosis water purification systems) ) under the pressure; when the aperture of the water passing hole of the waste water valve 410 is 0.4mm, the flow rate of the waste water can be about 200mL/min; when the water passing hole of the waste water valve 410 has an aperture of 0.7 mm, the flow rate of wastewater is about 650mL/min; therefore, the flow rate of wastewater can be limited by limiting the pore size. The specific size of the water through hole needs to be selected according to the water purification capacity of the reverse osmosis filter element 200. When the water purification capacity of the reverse osmosis filter element 200 is high, the aperture of the water through hole can be set smaller. The waste water valve 410 can be a normally closed direct-acting solenoid valve. During normal use, the valve port of the waste water valve 410 remains closed. The wide flow channel allows a large amount of water to flow through quickly, so as to achieve the purpose of better flushing the reverse osmosis water purification system.
