Description
技术领域 technical field
本实用新型涉及反渗透过滤装置的清洗设备领域技术，尤其是指一种单段式反渗透过滤装置的渗透膜清洗系统。The utility model relates to the technical field of cleaning equipment for a reverse osmosis filter device, in particular to a permeable membrane cleaning system for a single-stage reverse osmosis filter device.
背景技术 Background technique
目前，反渗透过滤装置广泛应用于城市饮用水、工业过程用水和废水的再利用。其采用了具有低能耗、无相变、无污染，且分离效率、浓缩倍数高的膜过滤技术，其中利用合适的膜分离来浓缩电镀液等的漂洗水，浓缩倍数可以达到100倍(以体积计)。膜分离后的浓缩液经过适当处理达到一定的镍离子浓度后回到电解槽，即回收镍，膜系统的透过液即纯水可以直接回到镀件的洗槽中，实现了电镀废水处理的零排放，不仅不会造成二次污染，而且还回收了废水中的有害重金属，变害为宝，使水资源得到再利用。At present, reverse osmosis filtration devices are widely used in the reuse of urban drinking water, industrial process water and waste water. It adopts a membrane filtration technology with low energy consumption, no phase change, no pollution, high separation efficiency and high concentration multiple, in which the rinsing water of the electroplating solution is concentrated by using a suitable membrane separation, and the concentration multiple can reach 100 times (by volume count). The concentrated solution after membrane separation is properly treated to reach a certain concentration of nickel ions and then returned to the electrolytic cell to recover nickel. The permeate of the membrane system, that is, pure water, can be directly returned to the washing tank of the plating parts, realizing the treatment of electroplating wastewater The zero discharge will not only cause no secondary pollution, but also recover the harmful heavy metals in the waste water, turning harm into treasure and reusing water resources.
反渗透过滤装置包括有单段式、两段式及多段式等多种渗透过滤设计，渗透膜是反渗透过滤装置的最重要的部件。其中，单段式渗透过滤又被称为一级浓缩，其在实际使用的过程中常会在膜元件中沉积许多污垢或悬浮物。藉此，为保持其正常的运作，需要定时对其进行清洗。然而传统的清洗方法是清洗液水路的流向与被过滤水水路的流向相同，由于被过滤水经膜元件过滤后，被过滤水中的污垢或悬浮物通常沉积于膜元件中被过滤水的流入侧，如果仍然将清洗液由其流入侧注入，那些可被溶解的污垢可以经过膜元件被冲走，但那些未能被溶解的悬浮物则仍会停留在膜元件的流入侧，而不能将彻底清洗掉。如此，清洗效果不理想。The reverse osmosis filtration device includes a variety of osmosis filtration designs such as single-stage, two-stage and multi-stage, and the osmosis membrane is the most important part of the reverse osmosis filtration device. Among them, single-stage permeation filtration is also called primary concentration, which often deposits a lot of dirt or suspended matter in the membrane element during actual use. Therefore, in order to maintain its normal operation, it needs to be cleaned regularly. However, in the traditional cleaning method, the flow direction of the cleaning liquid channel is the same as that of the filtered water channel. After the filtered water is filtered by the membrane element, the dirt or suspended matter in the filtered water is usually deposited on the inflow side of the filtered water in the membrane element. , if the cleaning liquid is still injected from its inflow side, the dirt that can be dissolved can be washed away through the membrane element, but the suspended solids that cannot be dissolved will still stay on the inflow side of the membrane element, and cannot be completely cleaned. wash off. In this way, the cleaning effect is not ideal.
