Electrical method treatment apparatus for increasing concentration multiple of circulation water

Abstract

The invention relates to an electrical method treatment apparatus for increasing the concentration multiple of circulation water. According to the electrical method treatment apparatus, electrode members contain alternating electrodes (5), a grounding electrode (6) and a grounding protection cover (7), wherein a group comprising at least the two alternating electrodes (5) is arranged inside the barrel-like grounding protection cover (7), and the grounding protection cover (7) is connected with the grounding electrode (6); and control members contain an oscillation circuit module (1), a power supply (2), a control circuit module (3) and an output module (4), wherein the power supply (2) and the control circuit module (3) are connected, and the control circuit module (3), the oscillation circuit module (1) and the output module (4) are connected. With the electrical method treatment apparatus, the concentration multiple of the circulation water in the prior art can be increased to more than 1 time; the pollution discharge of the circulation water is reduced by more than 1/2; the hardness, the conductivity and the turbidity of the circulation water are reduced by more than 30%; and the chloride ions are always less than the standard of 300 mg/L so as to substantially reduce the corrosion caused by increase of the chloride ions.

Description

technical field [0001] The invention relates to an IPC international patent classification C02F treatment equipment for water, waste water, sewage or sludge, which belongs to the technologies of electrolytic sterilization for chlorine reduction, electric desalination and pulse frequency antiscaling, especially an electric treatment device for increasing the concentration ratio of circulating water. Background technique [0002] Scaling in circulating water is actually a supersaturation phenomenon caused by the change of slightly soluble substances in the circulating water system under environmental conditions, which produces crystal nuclei. During the operation of circulating cooling water, with the consumption of volatile water, the concentration of various impurities in the water will decrease. Correspondingly, the probability of fouling will increase at the same time. At this time, the salinity, alkalinity, hardness, pH value and other indicators of the supplemental water ...

Problems solved by technology

[0011] All of the above work focuses on improving the scale inhibition performance of corrosion and scale inhibitors. Since the performance of common scale inhibitors is not only affected by the residence time, but also affected by the total hardness and salt concentration of the system, it is only necessary to change the scale inhibition perf
