Description

technical field [0001] The invention belongs to the technical field of domestic water treatment equipment, and in particular relates to an integrated anti-scaling sodium hypochlorite generator device and a realization method. Background technique [0002] The existing known sodium hypochlorite generator device is a large domestic water treatment equipment with a wide range of applications in this area. Although the sodium hypochlorite generator device has many advantages compared with similar products, it is often limited by the hard water source conditions, which makes the electrode surface of the electrolytic cell of the sodium hypochlorite generator device fouled and attached, and its electrolysis efficiency is obvious. decline. At present, the commonly used solutions mainly include: prefabricated demineralized water at room temperature before electrolysis to prevent scaling, setting electrodes to reverse poles for descaling, cooling the electrolytic cell to prevent scal...

Problems solved by technology

Although this electrochemical sterilizing water processor can realize the positive and negative electrode switching of the electrolytic cell after a certain period of reaction, and the instantaneous increase of the current of the electrode can effectively remove the dirt and scaling on the cathode, but there are still the following obvious shortcomings: one is to use positive and negative electrode Negative electrode switching, although it is effective to remove the dirt and scale on the cathode with a large current generated instantaneously, the electrode is greatly damaged, resulting in a greatly shortened life of the electrode; the second is to use the positive and negative electrode switching descaling method, which requires real-time shutdown processing , affecting the continuous operation of the electrolytic cell; third, the method of descaling after the scaling in the electrolytic cell directly affects and reduces the operating efficiency of the electrolytic cell

Although this device has the effect of reducing the generation of scale on the electrode surface and has a certain descaling effect, it still has the following obvious shortcomings: one is to use the positive and negative electrode switching descaling method, which directly affects the life of the electrode, affects continuous operation and reduces the electrolytic cell. Second, although the use of ultrasonic transducer foaming can reduce the formation of scale on the electrode surface, it cannot solve the problem of serious scale formation caused by the slow flow of electrolyte in the concentrated electrolyzer.
