Abstract

Relating to the technical field of electrochemical reaction, the invention discloses a coiled electrochemical reactor. The coiled electrochemical reactor comprises a first anode, a second anode, a cathode and an insulating layer. The first anode is wound on the second anode, the cathode is wound on the first anode, and the insulating layer is located between the first anode and the cathode. The invention also provides a heat exchanger comprising the coiled electrochemical reactor. The invention has the beneficial effects that: compared with the electrochemical descaling technology utilizing ahigh-alkalinity area of the cathode for descaling, no water scale is precipitated in the treatment process, design of a large number of parts or devices is not needed to complete scraping and discharging of water scale on the cathode, thus greatly simplifying the equipment design, and reducing manual intervention, at the same time, the structure is simple, maintenance is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of electrochemical reaction, in particular to a coiled electrochemical reactor, a descaling method and a heat exchanger. Background technique [0002] In order to reduce the adverse effects on pipelines and equipment due to the concentration of scale-forming ions in circulating water in the circulating water treatment system, electrochemical methods are often used to treat water. [0003] In the existing electrochemical treatment process, the scale-forming ions in the water are precipitated in the cathode area and deposited on the cathode plate in the form of scale deposition. Therefore, it is necessary to design a large number of components or devices to complete the scraping and discharge of the scale on the cathode. , causing the existing electrochemical devices to be relatively bulky and have low processing efficiency. [0004] In order to avoid scale treatment components, the electrochemical scale inhi...
