Distributive type device for monitoring leakage of storage tank bottom plate

Abstract

The invention discloses a distributive type device for monitoring leakage of a storage tank bottom plate. The device comprises a central shaft, wherein at least two conducting wires are arranged on the central shaft; each conducting wire is provided with a sensor wire; the sensor wires and the conducting wires are connected with an alarm box circuit; a conductive oil absorption wrapping layer is uniformly arranged at the periphery of the central shaft; a gap is formed between the oil absorption wrapping layer and the conductive wires; an oxygen barrier layer is arranged at the outer sideof the oil absorption wrapping layer; and a water-proof layer is arranged at the outer sideof the oxygen barrier layer. By arranging the device on the storage tank bottom plate evenly, when the oil storage tank bottom plate leaks, the leaked oil passes through the water-proof layer and the oxygen barrier layer to be absorbed by the oil absorption wrapping layer; the oil absorption wrapping layer expands in size after absorbing the oil to make contact with all the conducting wires to make the conducting wires be in parallel connection, so that the resistance of the conducting wires and the sensor wires is reduced; and therefore, the electric current of the conducting wires and the sensor wires is increased correspondingly to confirm that oil leakage occurs, and the leakage of the storage tank bottom plate can be monitored in real time.

Description

technical field [0001] The invention relates to the leakage monitoring of the storage tank bottom, in particular to a distributed storage tank bottom leakage monitoring device. Background technique [0002] After the bottom plate of the storage tank leaks, it often leaks to the edge of the storage tank or is not discovered until the storage tank is overhauled. In 1995, KinderMorgan commissioned a soil engineering company to conduct a seepage experiment. The experiment used two storage tanks with diameters of 7.5 meters and 37.5 meters respectively. The center of the storage tank was used as the leakage point, and the leakage rate was 1 gallon per hour. In the experiment, the oil tank with a diameter of 7.5 meters found leakage at the edge of the tank foundation within one month, while the oil tank with a diameter of 37.5 meters still did not find leakage after one and a half years. Therefore, once the bottom plate of the storage tank leaks, it is difficult to find, and the ...

Problems solved by technology

Therefore, once the bottom plate of the storage tank leaks, it is difficult to find out, and the small leakage will cause the foundation of the storage tank to be eroded, and major accidents are prone to occur

At present, there is no online monitoring device for storage tank floor leakage reported in our country
