Abstract

The invention provides a device for guaranteeing normal operation of a sacrificial anode, wherein a steel framework is arranged outside an anode steel core and the body of the sacrificial anode; an inside mesh enclosure and an outside mesh enclosure are arranged on the steel framework; a high molecular porous sleeve is arranged between the inside mesh enclosure and the outside mesh enclosure; a blowdown apparatus is mounted under the inside mesh enclosure and the outside mesh enclosure. The device has the advantages that an anode in sea mud is provided with excellent working environment, the problems of current efficiency drop and passivation or reversing of the sacrificial anode in the sea mud are solved, the sacrificial anode is inhibited from being directly covered with sea water / matters or wastes, the use effect and the service life of the sacrificial anode are guaranteed and the replacement and maintenance costs of the anode are reduced. Besides, the device is simple to manufacture, convenient and quick to mount, low in cost, high in applicability and wide in application range; the device can be applied to a back-silting port, a submarine pipeline, an offshore drilling platform and the like.

Description

technical field

[0001] The invention belongs to the technical field of anticorrosion, and in particular relates to a device for ensuring the normal operation of sacrificial anodes. Background technique

[0002] As an important anti-corrosion technology, sacrificial anode cathodic protection technology is widely used in petroleum, chemical, transportation and other fields. A sacrificial anode is an electrode that protects its coupled cathode (steel structure, etc.) by increasing its own corrosion rate. Its working performance is closely related to factors such as chemical composition, organizational structure, working environment, and surface state. At present, the commonly used sacrificial anodes include aluminum alloy sacrificial anodes, magnesium alloy sacrificial anodes and zinc alloy sacrificial anodes. Among them, the aluminum alloy sacrificial anode is widely used in the marine environment due to its high cost performance and large actual capacitance. The technical p...
