Abstract

The invention discloses a capacitive desalination filter element. The capacitive desalination filter element is provided with a capacitive desalination unit, wherein a flow passage for flowing of rawwater is arranged inside the capacitive desalination unit, the length of the raw water in the capacitive desalination unit is defined as A, the width of the capacitive desalination unit is defined asB, and A and B meet the relation that A>B>0. According to the capacitive desalination filter element, the length of the flow passage of the raw water in the capacitive desalination unit is increased under the situation of not changing the volume, so that the desalination effect is improved; and meanwhile, since the volume of the capacitive desalination filter element is not changed and the lengthof the flow passage is increased, the flow velocity of the raw water inside the capacitive desalination unit is increased, a double-electrode layer can be lowered, desalination efficiency can be improved, anti-pollution performance can be improved, and the life of the capacitive desalination filter element can be prolonged. A water treatment device is provided with the capacitive desalination filter element and a shell. The water treatment device has the advantages of being simple in structure, small in size, free of noise and free of pressure increase and can be directly assembled to a faucet.

Description

technical field [0001] The invention relates to the field of domestic capacitor desalination water production, in particular to a capacitor desalination filter element and a water treatment device with the filter element. Background technique [0002] Capacitive desalination technology uses charged electrodes to absorb ions in water, and the ions are gradually enriched in the electrodes on both sides, and the ion concentration in the channel is greatly reduced to achieve the purpose of water purification. When the electrode is regenerated, the electrode is reversed or short-circuited, and the adsorbed ions on the surface of the electrode are quickly desorbed and taken away by the water flow in the channel to form concentrated water. Capacitive desalination filter can also absorb residual chlorine and organic pollutants in water. The volume limitation of the capacitive desalination filter element in the prior art results in a limitation of the length of the flow channel, and...
