Abstract

PURPOSE: To carry out the corrosion prevention with a welded stainless steel part and the vicinity thereof as a cathode, by mounting a sacrificial electrode on the inner surface on the cooling water side of an ozonizer body on the end plate or near there.
CONSTITUTION: Round holes corresponding to two grounding metallic electrodes 2 are perforated on an end plate 4, and a metallic core 18 of a sacrificial electrode 17 consisting of Zn, Mg, Al or an alloy thereof is mounted thereon by the welding and connected with the end plate 4 electrically through the welded part 19. The end plate 4 is then fixed on the inner surface on the cooling water side of an ozonizer body 1 to mount the electrodes 2 on the round holes by the welding. The material of the sacrificial electrodes 2 is a base metal compared with iron, and these metals are as an anode dissolved in water to carry out the corrosion prevention with the surface of the welded stainless part as a cathode. OH ions formed on the surface near the welded part which becomes the cathode make the surface partially alkaline, and the Ca and Mg in the water are attached to the surface as a scaly film, thus enhancing the corrosion prevention gradually.
