Abstract

The invention discloses a carbon dioxide aeration electrochemical descaling device and method and belongs to the technical field water treatment. The device comprises a reactor barrel, a plurality ofcathode plates, a plurality of anode plates, an ultrasonic cleaner and an aeration pipe. Carbon dioxide is fed in the process of continuous water treatment through the aeration pipe for aeration, so that carbonate ions in water are supplemented, further removal of calcium ions is promoted, and ion migration and chemical reaction around the pole plates are promoted; aeration action delays deposition of scaling substance on the surface of each pole plate, and the objective of cleaning the pole plates can be achieved through joint action of the aeration pipe and the ultrasonic cleaner. The deviceis reasonable in structural design, the problem of hardness ion removal rate reduction caused by water alkalinity reduction in the process of continuous water treatment is solved, and electrochemicaldescaling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a carbon dioxide aeration electrochemical descaling device and method. Background technique [0002] Scaling problems exist in the use of industrial circulating cooling water, which affects the heat exchange efficiency of equipment. Usually, scale inhibitors are added to control the scaling tendency of calcium and magnesium hardness ions. However, adding antiscalants will bring secondary pollution, and hardness ions still exist in the water body, posing certain risks. The electrochemical method can generate a strong alkaline environment through the in-situ reaction of the cathode, and realize the precipitation of hardness ions such as calcium and magnesium in circulating water. It is a very potential descaling technology for circulating water. However, the existing electrochemical descaling devices do not take into account the decrease in the removal rate of ...
