一、加氯工艺及其存在问题我厂循环冷却水系统,循环水量18000～20000M~3/H,加氯机四台ZJ—1型,上海自来水公司制造的。每台加氯量5～45kg/H,平时两开两备。在系统漏氨的情况下,如氨含量高达60ppm,回水余氯量还能达到0.5～1.0ppm指标范围内。当压力水流经水喷射器时,山于流道截面积变小,流速增大,水的静压下降产生负压,使中转玻璃罩呈真空状态。液氯在氯瓶内汽化变成氯气逸出,高速流入旋风分离器,产生离心力,使氯气中混有的杂质在旋风分离器得到分离,杂质沉积在底部,氯气从上部流出。氯气进入弹簧膜阀后,依靠自身的
First, the chlorination process and its problems Our company’s circulating cooling water system, circulating water volume 18000 ~ 20000M ~ 3/H, chlorinator four ZJ-1 type, made by the Shanghai Water Company. Each chlorinating amount is 5 ~ 45kg/H, usually two open two preparations. In the case of ammonia leakage in the system, if the ammonia content is as high as 60 ppm, the chlorine content in the return water can still reach the target range of 0.5 to 1.0 ppm. When the pressure water flows through the water injector, the cross-sectional area of the flow channel becomes smaller and the flow velocity increases, and the static pressure of the water drops to generate a negative pressure, so that the relay glass cover is in a vacuum state. The liquid chlorine is vaporized in the chlorine bottle to become chlorine, and it flows into the cyclone separator at high speed to generate centrifugal force. The impurities mixed in the chlorine gas are separated in the cyclone separator, impurities are deposited at the bottom, and chlorine gas flows out from the upper part. After the chlorine gas enters the spring membrane valve, it depends on its own
