| 离子交换树脂再生方法（即离子交换树脂如何再生）： Regeneration method of ion exchange resin (i.e. how to regenerate the ion exchange resin): 1、阳离子交换树脂再生 1. Regeneration of cation exchange resin ①、配酸，比重≥3，同时将阳床内水全部放空； ① , acid, specific gravity ≥ 3, and vent all the water in the cation bed; ②、打开进酸阀、上排阀，其他阀门全部关闭，打开酸泵； ② . open the acid inlet valve and upper discharge valve, close all other valves and open the acid pump; ③、待进酸液面超过树脂以上500px后，开启下排，下排流量和进酸流量相同，此时流量控制在600-1000L/h，进酸时间不低于40分钟。 ③ . when the acid level is more than 500px above the resin, start the lower discharge. The flow of the lower discharge is the same as that of the acid inlet. At this time, the flow is controlled at 600-1000l / h, and the acid inlet time is not less than 40 minutes. 阳床清洗进酸完毕后可直接进行清洗，先开启砂过滤，精密过滤，精密过滤处于上排上进状态。放掉阳床进酸管道、上进管道内的残酸，方法是开启上进下进，下排开启进酸阀，此时将精密过滤出水阀打开、关闭上排阀，将进酸管道内的残酸冲洗到酸槽后关闭进酸阀；关闭阳床下进阀，开始进行清洗，清洗时打开阳床上排阀，阳床内的水须始终漫过树脂，注意不要使树脂失水；清洗到下排阀出水PH值为7左右（接近中性）为止。 The cation bed can be cleaned directly after acid feeding. First, turn on sand filtration, precision filtration, and precision filtration is in the upper row state. Discharge the residual acid in the acid inlet pipe and the upper inlet pipe of the cation bed. The method is to open the upper inlet and the lower inlet, and open the acid inlet valve in the lower discharge. At this time, open and close the precision filter outlet valve, and flush the residual acid in the acid inlet pipe to the acid tank, and then close the acid inlet valve. Close the lower inlet valve of the cation bed, and start cleaning. When cleaning, open the upper discharge valve of the cation bed, and the water in the cation bed must always overflow the resin, and inject Do not dehydrate the resin; clean until the pH value of the outlet water of the lower discharge valve is about 7 (close to neutral). |
