Low and high voltage combined electrochemical water treatment device and method

Abstract

The invention discloses a low and high voltage combined electrochemical water treatment device and method and relates to the technical field of water treatment. The low and high voltage combined electrochemical water treatment device comprises a low-voltage electrochemical water treatment device and an electrostatic water treating unit, wherein the inlet of the low-voltage electrochemical water treatment device is communicated with a main water inlet pipe; the low-voltage electrochemical water treatment device is connected with an automatic cleaning mechanism and the electrostatic water treating unit; the low-voltage electrochemical water treatment device is in a plug flow structure. The low and high voltage combined electrochemical water treatment device combines the electrostatic water treating unit with the plug flow type low-voltage electrochemical water treatment device, thereby being capable of firmly complexing ions flowing out of a low-voltage electric field, solving the deficiency of the low-voltage electric field and increasing the scale preventing rate to higher than 98% without increasing the energy consumption too much. The low and high voltage combined electrochemicalwater treatment device is large in water treatment volume, wider in treated hardness and concentration ranges compared with the prior art, and applicable to treating both medium or low-hardness waterand medium or high-hardness water. The low and high voltage combined electrochemical water treatment device achieves semi-automatic cleaning and maintenance, is simple, labor-saving, rapid and pollution-free in operation and reduces the invested cost by one third compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a low-voltage and high-voltage combined electrochemical water treatment device and method. Background technique [0002] There are two independent devices for circulating water electrochemical water treatment, one is a low-voltage electrochemical water treatment device, and the other is a high-voltage electrostatic water processor. Practice shows that: the low-voltage electric field reduces and removes scaling ions (Ca 2+ , Mg 2+ ) Especially for high hardness water, the probability is less than 80%. This deficiency has become the key to whether the low-voltage electric field water treatment can achieve the water treatment effect. Many researchers focus on power and current density, but no matter how high the power is, it cannot prevent the ions taken away by the outflow of water, so there is no better effect except for more power consumption. [0003] The original low...

Many researchers focus on power and current density, but no matter how high the power is, it cannot prevent the ions taken away by the outflow of water, so there is no better effect except for more power consumption.

[0003] The original low-voltage electric field water processor needs to be manually cleaned regularly. The cleaning cycle of domestic products is about 20 days. It takes 40-50 minutes to restore, and it takes time and effort to clean up
