Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like figure 1 Shown: a non-membrane electrodialysis capacitive desalination device, including a cathode 1 and an anode 2 that are made of inert materials and arranged in conjunction with each other. The cathode 1 and anode 2 arranged in parallel on both sides of the cavity are in a flat plate structure and applied voltage After a constant voltage electric field of 0.5-10 volts, a capacitor with an aspect ratio of 5-10 is formed. In the cavity between the cathode 1 and the anode 2, there are also two porous plates 3 that are relatively inclined to form an open triangle. The sharp angle of the open triangle formed by the porous plate 3 is set by adjusting the aspect ratio of the capacitor, and the distance between the closed tip of the two porous plates 3 and the water inlet end of the cathode 1 and the anode 2 is the same as that of the cathode 1 ...

Abstract

The invention discloses a non-membrane electrodialysis capacitance desalting device which comprises a cathode (1) and an anode (2), two porous plates (3) which form an opened triangle are arranged between the cathode (1) and the anode (2), a closed top end of each porous plate (3) faces the water inlet direction and an opened end of the porous plate (3) faces the water outlet direction, and the area between the porous plates (3) forms a low salinity water outlet area (4) and the areas between the porous plates (3) and the adjacent cathode (1) or anode (2) form high salinity water outlet areas (5) respectively; the arranged porous plates (3) can block the damage to the zwitterion separation phenomenon caused by the influence of turbulence to the electric field applied between the cathode (1) and the anode (2), so that malposed zwitterion caused by turbulence under the electric field function penetrates through the porous plates (3) and then flows out of the low salinity water outlet area (4). According to the non-membrane electrodialysis capacitance desalting device, zwitterion separation occurs to the high salinity water, the separation effect is not disturbed by the turbulence, the efficiency and the usability are high, and the maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of desalination, in particular to a non-membrane electrodialysis capacitive desalination device which has high treatment efficiency for high-salt wastewater and is easy to maintain because it has no membrane. Background technique [0002] At present, the electrodialysis method is one of the main methods for desalination of high-salt water. Usually, multiple pairs of anion-cation exchange membranes are alternately placed side by side to form multiple compartments. Flowing through multiple compartments, due to the action of the electric field, the anions and cations move in opposite directions respectively, and the cations pass through the cation exchange membrane and enter the adjacent compartment and are blocked by the anion exchange membrane on the other side of the compartment, while the anions pass through the anion exchange membrane in the opposite direction. After entering the adjacent compartment on th...
