Electrostatic desalination testing device and method

Abstract

The invention discloses an electrostatic desalination testing device. The electrostatic desalination testing device comprises a direct-current voltage-stablizing power supply, a magnetic force heating stirrer, a conductivity determinator, a liquid storage container and an electrode module, wherein the upper part of the liquid storage container is open and the liquid storage container is filled with a water sample; the liquid storage container is put on the magnetic force heating stirrer. According to the testing method of the electrostatic desalination testing device, the interval between two electrode plates is adjusted by a telescopic rod; the voltage is regulated by the direct-current voltage-stablizing power supply; the magnetic force heating stirrer is adopted so that the water sample fully flows in the liquid storage container; the conductivity determinator monitors the conductivity of the water sample in the liquid storage container, and a curve graph which shows the change of the conductivity with time is drawn, thereby obtaining the optimal voltage and the optimal interval between the electrode plates. The electrostatic desalination testing device is simple in structure, is simple and convenient to operate, and is good in adsorption of the electrode module, and can be used for measuring the optimal voltage and the optimal interval between the electrode plates under the optimal desalination effect by regulating the applied voltage and the interval between the electrode plates.

Description

technical field [0001] The invention belongs to the technical field of brine desalination, and in particular relates to an electrostatic desalination test device and a test method. Background technique [0002] The desalination of seawater and brackish water is the key to solving the shortage of global fresh water resources. The desalination of seawater and brackish water is to use seawater or brackish water to desalinate to produce fresh water. At present, my country's per capita water resources are about 2100m 3 , which is 1 / 4 of the world's per capita share. my country has been listed by the United Nations as one of the 13 most water-scarce countries. Most of the per capita water resources in coastal industrial cities are less than 500m 3 , in a state of extreme water shortage, it is imperative to vigorously develop the seawater or brackish water desalination market. Electrostatic desalination technology has developed rapidly in the desalination methods of seawater or b...
