我公司所属各水厂的混凝剂都为重力式加注,溶解池位置较高。过去投加混凝剂时,必须将溶解的固态硫酸亚铁或硫酸铝用人力提升至溶解池,因用量较多,劳动强度较大。我们也曾用水射器将矾液直接提升加注,但因水解液极易堵塞,投加量不易控制。后将加矾管接一真空器(用水射器形成真空),用以提升溶液,这样,操作方便, The coagulants of all the water plants of our company are gravimetrically filled, and the dissolution pool is in a higher position. In the past, when the coagulant was added, the dissolved solid ferrous sulfate or aluminum sulfate must be manually raised to the dissolving tank. Due to the large amount of labor, the labor intensity is large. We have also used helium emitters to raise the mash directly. However, because the hydrolyzate is easily blocked, the dosage cannot be controlled easily. After that, a vacuum device (water ejector to form a vacuum) will be added to the tube to increase the solution. In this way, the operation is convenient.
