Description
Technical Field
The utility model belongs to the technical field of metal pipeline corrosion protection, a sacrificial anode technology intelligence on-line monitoring device is related to.
Background
The cathode protection method of sacrificial anode, also called sacrificial anode protection method, is a method for preventing metal corrosion, i.e. using active metal with strong reducibility as protective electrode, and connecting it with protected metal to form primary cell, using active metal with strong reducibility as negative electrode and making oxidation reaction to consume it, using protected metal as positive electrode and can prevent corrosion. The sacrificial anode protection method is applied to long-distance buried metal pipelines such as electric power chemical industry metal pipelines, oil and gas conveying pipe networks, urban water supply pipe networks and the like in a large scale at present. The longest design life of the sacrificial anode process can reach dozens of years, the consumption of the sacrificial anode block can be accelerated along with the change of the soil resistivity caused by the change of the conditions of the water content, the salt content and the like of the soil environment, and the protection voltage of the sacrificial anode block can be changed, so that the monitoring of the protection potential is an important work for the operation and maintenance of the sacrificial anode process. At present, the monitoring of the protection voltage of the sacrificial anode block requires that a technician periodically go to each test pile of the pipeline arrangement to test and record the protection potential. This approach has three disadvantages: firstly, the input labor time is high in cost and low in efficiency, and particularly, when the cathode protection testing pile is used for an oil-gas pipeline for long-distance transmission, each cathode protection testing pile is far away, and special technicians are required to carry special tools to measure the distance; secondly, the pipeline monitoring state cannot be obtained in real time, and early warning cannot be provided in time when the sacrificial anode fails. The protection potential can not be obtained in real time, when the cathode protection voltage is insufficient due to the fact that the environment near the metal pipeline is changed rapidly, or when the sacrificial anode fails due to some reason, the metal pipeline is in an underprotection state, long-time underprotection can lead to corrosion aggravation of the metal pipeline, and the service life of the pipeline is shortened. And thirdly, the long-distance pipeline has more test piles, the surrounding environment of the test piles is poor, the test piles are monitored manually at regular intervals, and the operation and maintenance cost is high.
