Description

Technical Field

[0001] The utility model relates to the field of storage tank anti-corrosion, in particular to a storage tank anti-corrosion protection device. Background Art

[0002] In many industrial and chemical fields, liquid storage tanks are important equipment for storing various liquids. However, traditional liquid storage tanks often face a series of problems, especially in severe rainy and snowy weather conditions and when tank leakage cannot be repaired in time.

[0003] Severe rain and snow weather can have a serious impact on storage tanks. Rainwater and snow water may seep into the interior of the storage tank, causing the tank to become damp, thereby accelerating the rate of corrosion. In addition, if the tank leaks and cannot be repaired in time, the liquid in the tank will come into contact with the external environment, further aggravating the degree of corrosion.

[0004] The bottom of the tank also faces challenges after it is put into use. Long-term static friction will cause the anti-corrosion layer to gradually wear away, while the corrosive effect of moisture will erode the anti-corrosion layer, making it lose its function of protecting the tank. Worse still, once the anti-corrosion layer is damaged, anti-corrosion operations become difficult or even impossible. This means that the tank will be more vulnerable to corrosion, forming a vicious cycle.

[0005] This vicious cycle will lead to a series of problems. Corrosion will not only reduce the service life of the storage tank, but may also cause liquid leakage and pollute the environment. At the same time, water absorption will increase the water content of the liquid in the storage tank, affecting the quality and stability of the liquid. Further corrosion will aggravate the damage to the tank, increase maintenance costs and safety risks. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In one embodiment, Figure 1 As shown: a tank corrosion protection device, including a tank bottom plate 1, a tank 2, a liquid accumulation pit 3 and a bracket 4, the tank 2 is arranged on the tank bottom plate 1, characterized in that: the liquid accumulation pit 3 is arranged around the tank bottom plate 1, the bracket 4 is installed above the liquid accumulation pit 3, the wire 6 passes through the bracket 4 and is fixed to the bracket 4, the two sides of the liquid accumulation pit 3 are sloped, an anode sacrificial block 5 is arranged in the liquid accumulation pit 3, the anode sacrificial block 5 is a magnesium block or a zinc block, the anode sacrificial block 5 is connected to the tank bottom plate 1 through the wire 6, the wire 6 is a copper wire, a current monitoring instrument 7 is arranged on the wire 6 and is fixed to the bracket 4.

[0020] In one embodiment, Figure 1As shown: The method of using the device is as follows: When the storage tank 2 is in rainy and snowy weather or has a leak, water will accumulate at the bottom of the tank 2, causing corrosion of the tank bottom plate 1 and the surrounding area of ​​the bottom plate. At this time, the water at the bottom of the storage tank 2 will flow into the liquid accumulation pit 3 by itself, and form an ionization circuit through the anode sacrificial block 5, the wire 6 and the tank bottom plate 1. Since the anode sacrificial block 5 is more active than the tank material, it is corroded first, thus realizing corrosion protection of the tank bottom plate 2. A current monitoring instrument 7 is set on the wire 6 to realize corrosion current monitoring.
