Problems solved by technology

Due to the large amount of evaporation, the ion content in the circulating water continues to increase, and it is easy to scale a lot, which affects the operation of the equipment
In order to reduce the ion content, only through continuous drainage and water replenishment, but this method is a waste of water resources, and the effect is not good
If the general chemical method is used, a large amount of precipitation will also be formed, which is not easy to clean, and it is easy to cause corrosion of the equipment, increase the failure rate, and reduce the service life

Abstract

The invention provides an electrolysis and side-filtration device for industrial circulating water. The electrolysis and side-filtration device comprises a circulating pump and an electrolytic cell, wherein negative plates and positive plates in the electrolytic cell are arranged in a staggered manner; the positive plates are arranged in matched positive chambers respectively; diaphragms are arranged on the two side surfaces, parallel to the positive plates, of every positive chamber; and scrapers are arranged on the negative plates in a matched manner. Directed at the characteristics that circulating cooling water is high in alkalinity, serious in scaling and not suitable for usage of chemical agents, a targeted electrolysis manner is adopted to separate cations mainly containing calciumand magnesium ions and anions mainly containing chloride ions in the circulating water. Anions in acidic effluent of an anode water outlet pipe are oxidized to generate hypochlorite radicals, so a composite strong oxidant is formed and can kill bacteria, remove algae and balance a pH value after entering a circulating water tank; and cations in alkaline effluent of a cathode water outlet pipe areprecipitated and removed in a precipitation tank, then water returns to the circulating water tank, and ions contained in the treated circulating water are remarkably reduced.

Description

technical field [0001] The invention relates to a filtering device, in particular to an industrial circulating water electrolysis side filtering device and a method for industrial circulating water side filtering. Background technique [0002] Nowadays, many industrial equipment adopt circulating water cooling equipment, which is cooled by the evaporation and heat absorption of water. Due to the large amount of evaporation, the ion content in the circulating water continues to increase, and it is easy to scale in large quantities, which affects the operation of the equipment. In order to reduce the ion content, there is only continuous drainage and water replenishment, but this method is a waste of water resources, and the effect is not good. If the general chemical method is used, a large amount of precipitation will also be formed, which is not easy to clean, and it is easy to cause corrosion of the equipment, increase the failure rate, and reduce the service life. Cont...
