Send Inquiry1.Introduction
In order to avoid cathode scaling and anode passivation, the cathode and anode of the electric flocculator need to be constantly switched, that is, after a period of time, the cathode is converted to anode, and the anode is converted to cathode. In the existing Electrocoagulation For Water Treatment technology, polarity switching is carried out by setting a timer and manually setting a time cycle.

4.Working principle
However, due to different water quality conditions (such as different hardness, alkalinity, salt content, temperature, pH, etc.), the cathode and anode reverse time of the electric flocculation device are different, so according to the same cycle reverse electrode treatment of different water quality, the anti passivation effect is not good. In order to improve the anti passivation effect, it is necessary to manually adjust the reverse period according to different water quality. Manual debugging is troublesome, the existing electric flocculation device can not automatically adjust the reverse period with the change of water quality, resulting in the unstable effect of electric flocculation. After passivation, the resistance and power consumption of the electrode will increase. The patented technology of membrane flight improves the electrode reversing time of electric flocculation, that is, it can automatically control the reverse time of positive and negative polarity of power supply by measuring the increase rate of resistance between anode and cathode in real time, which can be said to be an intelligent reverse technology.
The specific principle is as follows: with the progress of electrocoagulation electrolysis, impurities, calcium and magnesium ions in water are gradually deposited on the cathode, and strong oxidation reaction takes place on the anode, resulting in the formation of a dense passivation layer of metal oxide film on the anode surface, which leads to the increase of resistance. The control system detects the current value (I) and voltage value (U) between the anode and cathode in real time, and continuously calculates the resistance increase rate DR / R. when the resistance increase rate reaches the set value in the control system, the control system immediately sends the command to reverse the positive and negative polarity to the power supply, reverses the cathode anode, and clears the current value of the resistance increase rate, and recalculates the electricity after the electrode reverses The resistance increase rate, Dr / R, enters the next commutation cycle. In this way, the control system automatically controls whether the positive and negative poles of the power supply reverse according to the increase rate of resistance between the anode and the cathode. According to different water quality, it dynamically adjusts the reversal time of the positive and negative poles of the power supply, effectively prevents the anode from being passivated, improves the electric flocculation effect, and avoids the problem that the electric flocculation effect is not good due to the use of the same fixed reverse cycle power supply for different water quality Question. Moreover, it does not need to change the reverse cycle of power supply according to the water quality, which reduces the labor cost
