我厂用下述方法溶解硫化钠,多年的实践证明,设备简单,效果很好。把溶解池设在低于地面处,在其2/3的高度处设一个格筛,把硫化钠置于格筛上,加满清水,让硫化钠完全浸没在水中。给水管的出口不宜大并伸至池底,以造成较强的向上流动的水流,加速硫化钠的溶解。硫化钠溶液用泵扬送至给药室。溶解池出口闸阀要装设于池内(位于接近池底处),这可避免闸阀被硫化钠腐蚀造成漏药,闸阀用连杆引出液面用手轮启闭。
I plant the following method to dissolve sodium sulfide, years of practice has proved that the equipment is simple, the effect is very good. Set the dissolution tank below ground, set a grid at 2/3 of its height, place sodium sulfide on a grid and fill it with water to completely submerge it in water. Water pipe exports should not be large and extended to the bottom of the pool to create a strong upward flow of water to accelerate the dissolution of sodium sulfide. Sodium sulfide solution was pumped to the delivery chamber. Dissolution tank outlet gate valve to be installed in the pool (located near the bottom of the pool), which can prevent the gate valve corrosion caused by sodium sulfide leakage, gate valve rod with the level of the hand wheel opening and closing.
