Abstract

The invention provides a drainage device and a system for controlling concentrated water discharge in the water purification process. The drainage device comprises a valve cavity, a flow meter, a transmission shaft and a control part. The control part is used for controlling the movement of the transmission shaft to adjust the liquid flow of the flow meter in the valve cavity. According to the drainage device disclosed by the invention, the instantaneous impact of the liquid on the valve cavity is inhibited, and the vibration caused by the liquid is relieved; a special structural design is adopted to facilitate the control of the flow of concentrated water; the device is suitable for different pressure environments, and the purposes of being small in size, controllable in laminating area and small in friction force is achieved; leakage is avoided, and it is easy to maintain and clean; and the problem of concentrated water discharge disorder caused by water hammer in a water purification system is solved.

Description

technical field [0001] The application relates to the field of water purification, in particular to a drainage device and a system for controlling the discharge of concentrated water during the water purification process. Background technique [0002] The traditional water purification system using reverse osmosis membrane uses a booster pump as the power of the water purification system. When the discharge ratio of concentrated water is fixed, due to the physical characteristics of the membrane, as the water temperature decreases, the recovery rate of purified water decreases, and the discharge ratio of concentrated water gradually increases, resulting in a large waste of water resources. When the concentrated water flow is adjustable, the concentrated water discharge is mainly adjusted through the valve. This method belongs to the way of human intervention, which can only achieve simple fuzzy adjustment, but cannot realize precise control, and will either cause waste of p...
