Problems solved by technology

[0002] In recent years, with the increasing demand for crude oil in the domestic and foreign markets, oil refineries have continuously increased their requirements for the storage and transportation of crude oil and refined oil products, and related oil storage tank leakage detection and leakage prevention technologies have been widely used. Crude oil processing and storage and transportation enterprises have adopted double-layer tank bottom structure to reduce oil leakage and environmental pollution, and installed corresponding detection equipment to detect oil leakage points, but the tank bottom detection equipment has large volume, complex structure, The disadvantage of low sensitivity

Embodiment Construction

[0034] Such as Figure 8 , 9 As shown, the method of the present invention is realized by the multi-channel industrial monitoring system for oil storage tank bottom plate leakage, adopting 26 alarm detection devices (address numbers are A01~A26), installed in the asphalt sand layer below the oil product storage tank bottom plate, in the The bottom plate of the oil storage tank is evenly arranged within the range covered by the cover, and it can also be arranged in the area corresponding to the bottom plate that is prone to leakage according to the actual situation. Address coding is performed for each alarm detection device to determine the communication address number, and the RS485 bus passes through The explosion-proof safety barrier 12 and the RS485 / 232 conversion unit 13 communicate with the upper monitoring computer 14 .

[0035] Such as image 3 , 4 As shown, the system is composed of an alarm detection device and a host monitoring computer 14, wherein the alarm dete...

Abstract

The invention relates to a method for monitoring leakage of a bottom plate of an oil storage tank, which comprises the following steps: arranging a leakage warning and detecting device of the bottom plate of the oil storage tank below the bottom plate of the oil storage tank; powering the leakage warning and detecting device of the bottom plate of the oil storage tank and carrying out initialization operation; according to the electric field induction principle, acquiring voltage data by using electric field imaging technology and transmitting the voltage data; when the voltage variation is larger than a set value, sending out leakage warning signals of the bottom plate of the oil storage tank, displaying warning position, and recording warning data and time; returning to the step of acquiring field data and transmitting the field data, and circulating the step; and when the detection device has a power fail, ending the detection process. The method has the characteristics of high measuring accuracy, quick response speed, simple method, easy realization, strong anti-disturbance capability, self-checking function, long service life, and wide application field, etc.

Description

technical field [0001] The invention relates to a data acquisition technology for leakage of equipment caused by corrosion, in particular to a method for monitoring the leakage of the bottom plate of an oil storage tank. Background technique [0002] In recent years, with the increasing demand for crude oil in the domestic and foreign markets, oil refineries have continuously increased their requirements for the storage and transportation of crude oil and refined oil products, and related oil storage tank leakage detection and anti-leakage technologies have been widely used. Crude oil processing and storage and transportation enterprises have adopted double-layer tank bottom structure to reduce oil leakage and environmental pollution, and installed corresponding testing equipment to detect oil leakage points, but the tank bottom testing equipment has large volume, complex structure, The disadvantage of low sensitivity. Therefore, the study of a new generation of tank bottom...
