Static desalting system and testing method thereof

Abstract

The invention relates to a static desalting system and a testing method thereof. The static desalting system comprises an inlet water tank, a desalting device and an outlet water tank, wherein the inlet water tank communicates with the desalting device through a water inlet pipeline; the desalting device communicates with the outlet water tank through a water outlet pipeline; the water inlet pipeline is provided with a water pump and a liquid flowmeter along the liquid flow direction; the desalting device is connected with an electric conductivity meter; the desalting device comprises a shell; the left and right sides of the shell are respectively provided with a water inlet and a water outlet; a plurality of parallel plate electrodes arranged at intervals are arranged in the shell; the plate electrode on one side is connected with the positive pole of a direct-current stabilized voltage supply, and the plate electrode on the other side is connected with the negative pole; every two adjacent plate electrodes are arranged in an up-and-down staggered mode; each plate electrode comprises a rectangular steel plate; and both side surfaces of each rectangular steel plate are respectively bound with an activated carbon fiber fabric. The static desalting system has the advantages of simple structure, low manufacturing cost, favorable adsorbability of the plate electrodes, favorable desalting effect and high desalting efficiency, is simple to operate, and can measure the optimal water inlet flow under the optimal desalting effect by regulating the water inlet flow.

Description

technical field [0001] The invention belongs to the technical field of brine desalination, and in particular relates to an electrostatic desalination system and a test method thereof. 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 o...
