This application relates to a wastewater flow limiting device and a drinking water purification device, applicable to the field of drinking water purification equipment. It includes a housing, a cover, and a scale inhibitor. The housing includes an inlet, an outlet, and a flow limiting orifice. The cover is connected to the housing and defines a purification flow channel between the cover and the housing, allowing the wastewater to contact the scale inhibitor. The purification flow channel connects the inlet and the outlet. The flow limiting orifice connects the outlet and the purification flow channel, and the flow cross-sectional area of ​​the flow limiting orifice is smaller than the flow cross-sectional area of ​​the purification flow channel. The scale inhibitor is filled within the purification flow channel. This application fills the purification flow channel with a scale inhibitor. When wastewater flows through, the scale inhibitor reacts with calcium, magnesium, and other easily scale-forming ions in the wastewater, preventing scale formation and improving the long-term stable operation of the device in complex water quality environments. This avoids flow control failure and frequent maintenance problems caused by scaling. The flow limiting orifice effectively prolongs the contact time between the water flow and the scale inhibitor, allowing for a more complete scale inhibition reaction and improving descaling efficiency.

This utility model relates to a descaling device for an ion-exchange membrane electrochemical water treatment system. This utility model effectively solves the problems of inconvenient operation and inability to guarantee effective removal of impurities in some ion-exchange membrane descaling devices. The descaling device of this ion-exchange membrane electrochemical water treatment system uses a first driving component to move the descaling mechanism and vibration mechanism to corresponding positions on different ion-exchange membranes. A second driving component moves the descaling mechanism along the outer side of the ion-exchange membrane, allowing the descaling mechanism to rinse both sides of the ion-exchange membrane while simultaneously removing the washed-off scale and impurities, preventing impurities from re-adsorbing onto the ion-exchange membrane. The vibration mechanism provides high-frequency vibration to the ion-exchange membrane, dislodging impurities from the membrane and allowing them to be removed by the descaling mechanism. This effectively improves descaling efficiency and thoroughly cleans both sides of the ion-exchange membrane, resulting in better descaling effects. Furthermore, it requires no manual operation, has higher descaling efficiency, and is more convenient for descaling ion-exchange membranes in water treatment equipment.
