Electronic anti-corrosion inner container of electric water heater

Abstract

The invention discloses an electronic anti-corrosion inner container of an electric water heater. The electronic anti-corrosion inner container of the electric water heater comprises an electric water heater inner container and is characterized in that an electronic anti-corrosion instrument integrated with the electric water heater inner container is arranged on the electric water heater inner container; the electronic anti-corrosion instrument mainly comprises an anode, a reference electrode and a threaded connection base; the anode is a bar body made of iridium titanium; the end parts on the same side of the anode and the reference electrode are connected with the threaded connection base; the threaded connection base is in bolted connection with the electric water heater inner container via external screw threads; the anode and the reference electrode extend into the electric water heater inner container. Since the anode of the electronic anti-corrosion instrument integrated with the electric water heater inner container is an insoluble titanium anode, a layer of electronic oxidation protective film can be formed on the inner wall of the electric water heater inner container during a corrosion prevention reaction, a corrosion reaction is directly prevented, and decomposition products are avoided, so that water is prevented from being polluted.

Description

technical field [0001] The invention relates to anticorrosion technology in the field of electrochemistry, in particular to an electronic anticorrosion liner for an electric water heater. Background technique [0002] The anti-corrosion project of electric water heater liner belongs to the scope of electrochemistry, and its theoretical root comes from the principle of cathodic protection. Cathodic protection is to add a large amount of electrons to the metal to be protected, so that the metal to be protected is in a state of excess electrons as a whole, so that each point on the metal surface reaches the same negative potential, so that the metal atoms are not easy to lose electrons and become ions and dissolve into the solution , to achieve cathodic protection of metals. At present, the scope of application includes electric water heaters, solar water heaters, instant water heaters, boilers, water dispensers, metal water towers and other equipment. The liner of the electr...

Problems solved by technology

However, the processing technology of the enamel liner is relatively high. If the technology level is not enough, air bubbles or pinholes are likely to occur during the production process. At the same time, the enamel is relatively brittle, and scale explosions are likely to occur due to vibration and collision during transportation and installation. The enamel is in hot water. will gradually dissolve and peel off

The above factors will cause the ordinary steel plate of the electric water heater inner tank to be exposed, and water leakage will occur when the corrosion reaches a certain level.
