反渗透装置操作规程.pdf

1 第五章反渗透装置操作规程5.1 概况5.1.1 装置简介反渗透装置2003 年投入运行，由一台SJDF-15 自动反渗透装置组成，渗透流量15t/h，它的主要任务是对新鲜水进行净化处理，为三台蒸汽锅炉提供合格的软化水。5.1.2 工艺原理反渗透是通过渗透除去水中的离子、有机物、县浮物等杂质。与过滤器不同，水或溶液经过压力膜（“交叉流”过滤）被分为二部分并分别在膜的两边被收集。在足够的压力下，半透性的反渗透膜的作用为：让纯净水透过，将溶解性、县浮物的固体截留并浓缩。5.1.3 工艺流程从深水中或消防水罐来的新鲜水，经过原水泵进入多介质过滤罐，精密过滤器的预处理，再经一级泵增压进入反渗透装置，处理出来的净化水进入软水箱，浓度水排到循环水池。为了防止RO反渗透结垢，在精密过滤器前用加药泵加入MDC220 专用阻垢剂或六偏磷酸钠药剂。由于反渗透出水的PH值较低，为防止酸性水对锅炉的腐蚀，提高给水的PH值，在反渗透装置出口总管内由加药泵加入稀NaOH溶液，使出水的PH值大于 7。当膜表面积聚污物、沉淀物而降低渗透流量，影响渗透出水品质后，必须通过化学清洗和物理冲洗去除污物，方可再使用。5.1.4 工艺原则流程图见附图一5.2 工艺指标名称单位指标原水泵压MPa 0.18-0.2 进水压MPa 1.0 中间水压MPa 0.8 浓水压MPa 0.8 淡水量LPM 300 浓水量LPM 170 电导率s/cm 25 P H 7 5.3 开机准备5.3.1 对反渗透装置进行清扫5.3.2 对软水箱、管线、阀门、原水泵、增压泵、多介质过滤罐、精密过滤器等设备进行全面检查。5.3.3 对反渗透系统进行检查。2 5.3.4 对电气 ROC-2312反渗透控制器、控制柜进行检查。5.3.5 在阻垢剂、PH值剂桶中分别配制适量浓度的阻垢剂MDC220 和碱液 NaOH。5.4 开机运行5.4.1依次打开多介质过滤器出水阀和进水阀，同时检查过滤器上的其他阀是否处在关闭状态，有开启的应关闭。5.4.2依次打开下列阀门：进水阀、浓水阀、浓水排放阀、淡水阀、增压泵出水.5.4.3开启原水泵、增压泵，调整浓水阀，使泵压升至1.0MPa 左右，使浓水流量稳定在170LPM左右，淡水流量在300LPM左右。5.4.4打开浓水与循环池连通阀，关闭浓水排放阀。5.4.5检查淡水产水情况，淡水产量在300LPM左右，并在淡水排放口取样。5.4.6检查阻后剂和PH调节加药系统中泵运行加入阻垢剂和碱液情况。5.4.7运行正常后，记录好反渗透装置各设备的运行参数。5.5 停机5.5.1当软水箱液位达到95%后，打开淡水、浓水排放阀，关闭进水箱阀、循环连通阀。5.5.2调整一级泵回流阀，将泵压降至0.3MPa，低压冲洗10 分钟，停增压泵和原水泵。5.5.3依次关闭下列阀门：进水阀、浓水阀、淡水阀，完成停机。5.5.4.若长时间停运，应切断反渗透装置电源。5.6 注意事项5.6.1开机时，务必打开进水阀、泵的出口阀、浓水阀、浓水排放阀等，使整个工艺流程畅通，以防止泵压急聚上升，管道造成破坏。5.6.2如发现多介质过滤器出水水质变差，或在0.15MPa 下通水不畅，则应进行反冲洗。打开后排阀，再徐徐开启反进阀，逐步加大水量在此大流量下洗至出水与进水水质相近为止。5.6.3加高压泵不升压，则需打开泵的气排孔进行排气。5.6.4每次停机前要低压冲洗10 分钟。5.6.5加阻垢剂和碱液时，操作人员必须戴好防护手套，以防药品灼伤肌肤。5.7 维护保养5.7.1认真检查设备运行情况，有故障及时检修更换。5.7.2认真填写开机运行记录表。5.7.3每次停机要低压冲洗10 分钟。5.7.4每隔 6 个月或根据供水情况对反渗透膜进行清洗一次。5.8 对反渗透的清洗（具体参考反渗透说明书）5.9 附录5.9.1水处理设备一览表文档编码:CQ5V9O2R4E6
