Electrochemical water treatment device with electrode spacing regulation and control function

Abstract

The invention discloses an electrochemical water treatment device with an electrode spacing regulation and control function. The device comprises a pool body with opening on the upper and lower surfaces, wherein the pool body is made of an insulating material, a water inlet pipe is arranged on one side of the pool body, a water outlet pipe is arranged on the other side of the pool body, a fixed electrode is arranged in the pool body, a first electrode of an annular structure is arranged in the pool body, a first telescopic rod made of an insulating material is arranged above the pool body, thefirst telescopic rod penetrates through the first electrode, and a plurality of second telescopic rods connected with the first telescopic rod are arranged on the periphery of the first telescopic rod. According to the invention, different numbers of electrodes can be selected for participation according to different water treatment capacities while the water inlet rate is adaptively adjusted, and the rate difference between the water inlet pipe and the water outlet pipe is offset through the rotating conical rod, so that the water storage capacity in the pool body is improved, and the adsorption capacity of calcium, magnesium and sodium ions in unit time is improved; and when a small amount of water needs to be treated, the electrode area participating in water treatment can be reduced,so that the participation amount of the first electrode and the second electrode is reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the field of water treatment, in particular to an electrochemical water treatment device with the function of regulating the distance between electrodes. Background technique [0002] Electrochemical water treatment technology refers to the process of degrading pollutants in wastewater through certain chemical reactions, electrochemical processes or physical processes in a specific electrochemical reactor under the action of electrodes or an external electric field. At present, the position of the electrode plate is usually fixed, but the amount of water that needs to be treated in each time period is difficult to be constant. Therefore, when designing the specific surface area of ​​the electrode plate, it is usually designed according to the maximum amount of water to be treated, which leads to In order to deal with a small amount of water, the electrode plates are still all involved in water treatment, so that the electrode p...
