Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 Shown: a capacitive desalination device with cross-drain tubes, including two parallel-connected single-capacitor desalination mechanisms 1, and each single-capacitor desalination mechanism 1 is provided with relatively parallel long electrodes 3 and The separated capacitive desalting mechanism 2 composed of porous electrodes 4 is provided with ion guide tubes 5 intersected between the single capacitor desalting mechanism 1 and the separated capacitive desalting mechanism 2 to enrich the single capacitor desalting mechanism 1 with the opposite electrolytic The solution is introduced into the corresponding separated capacitive desalination mechanism 2, and then the current limiting through the porous electrode 4 avoids the destruction of the ion separation effect by the turbulent flow in the single capacitive desalination mechanis...

The invention discloses a capacitance desalter provided with cross diversion pipes. The capacitance desalter comprises single capacitor desalting mechanisms (1) which are arranged in parallel, separated type capacitor desalting mechanisms (2) formed by long electrodes (3) and porous electrodes (4) which are arranged relatively in parallel are arranged on the rear side of each single capacitor desalting mechanism (1), cross iron diversion pipes (5) are arranged between the capacitor desalting mechanisms (1) and the separated type capacitor desalting mechanisms (2) to guide solutions enriched with opposite electricity in the capacitor desalting mechanisms (1) into the separated type capacitor desalting mechanisms (2) corresponding to the solutions, low salinity water flows out of a low salinity water outlet area (6), and high concentration ionized water enriched in the positions of the long electrodes (3) flows out of high salinity water outlet areas (7) formed by the long electrodes (3) and the porous electrodes (4). According to the capacitance desalter provided with the cross diversion pipes, the zwitterion separation effect produced by the high salinity water is not affected by turbulence disturbance, the efficiency of the cross iron diversion pipes is improved, the usability is high, and the maintenance is easy.
Description
technical field [0001] The invention relates to the technical field of desalination, in particular to a capacitance desalination device with cross-drainage tubes which uses capacitance technology to treat high-salt wastewater and has the characteristics of high efficiency and easy maintenance. Background technique [0002] Capacitive desalination is to let the brine flow through a pipeline with a pair of flat porous electrodes (mostly carbon electrodes) with voltage applied on both sides. Significantly reduced technology, with the characteristics of simple structure and easy maintenance. The reason for using a porous electrode is to prevent inefficiency due to turbulent disturbances that would carry away ions enriched near the electrode. There is also a way to further improve the efficiency by adding a layer of anion and cation exchange membranes to the cathode and anode respectively. However, these methods have their own problems. After the electrode pores of the porous ...
