AI Technical Summary

Problems solved by technology

Since the pressure, flow velocity, flow rate, temperature, etc. of the crude oil in the oil pipeline are all changing, and the accuracy of the sensor is limited, it is difficult to detect when the leakage is small
Moreover, this type of detection often requires more time, and oil leakage or oil stealing cannot be found in time.

Embodiment 1

[0035] Embodiment 1. A method for automatic detection and alarm of oil pipeline leakage. It consists of setting a sending device at the source end of the oil pipeline to quantitatively add detection substances into the oil pipeline, setting a detection device at the end of the oil pipeline to quantitatively detect and recover the detection substances added to the oil pipeline, and comparing the added detection substances with the recovered detection substances. Analysis, if it does not meet the normal value, it is composed of steps such as sending an alarm signal. The detection substance is a solid pellet whose density is 95% to 105% of the density of the crude oil being transported, and is easy to separate from the crude oil, will not chemically react with the crude oil being transported, and will not be corroded by the crude oil being transported . The ball is made of ABS material

Embodiment 2

[0036] Embodiment 2. A method for automatic detection and alarm of oil pipeline leakage. It consists of setting a sending device at the source end of the oil pipeline to quantitatively add detection substances into the oil pipeline, setting a detection device at the end of the oil pipeline to quantitatively detect and recover the detection substances added to the oil pipeline, and comparing the added detection substances with the recovered detection substances. Analysis, if it does not meet the normal value, it is composed of steps such as sending an alarm signal. The test substance is a specially prepared yellow liquid, whose density is 95% to 105% of the density of the crude oil being transported, and is easy to separate from the crude oil, will not chemically react with the crude oil being transported, and will not be transported Crude oil corrosion.

Embodiment 3

[0037] Embodiment 3. An automatic detection and alarm device for oil pipeline leakage. It consists of a ball adding device installed at the source end of the oil delivery pipe, small balls added into the oil delivery pipe by the ball adding device, a filter screen installed at the end of the oil delivery pipe, and a ball collection detection device installed on the filter screen. Such as figure 1 shown. The density of the pellets is 95%-105% of that of the crude oil being transported, and it is easy to separate from the crude oil, and will not react chemically with the crude oil being transported, and will not be corroded by the crude oil being transported. The ball is made of ABS material with a diameter of 6mm. Embodiment 3 can detect holes with a diameter greater than 6 mm.

Abstract

The present invention relates to an oil pipe leakage automatic detection alarm method and its automatic detection alarm device. Said method includes the following steps: adding a certain quantity of detection material in source end of oil pipe, recovering detection material at terminal of oil pipe, comparing added quantity of detection material with its recovered quantity to make judgement. Said detection alarm device is formed from ball-adding device, small balls, filtering screen and ball-recovering detection device. The density of small balls must be 95%-105% of that of crude, and the diameter of screen hole of filtering screen is less than that of small ball, and the ball-adding device is formed from ball container, ball conveyer, pipe, valve, ball chamber, air compressor, oil tank and single chip processor controller, and the ball-recovering detection device is formed from pipeline, valve ball-oil separator, air compressor, oil tank, ball-storing device, ball-ercovering judgementdevice and single chip processor ball-recovering controller.

Description

technical field [0001] The invention belongs to the technical field of oil pipelines in the petroleum industry, and more specifically relates to an automatic detection and alarm method for oil pipeline leakage based on communication theory and an automatic detection and alarm device thereof. Background technique [0002] At present, oil pipeline leakage or stolen oil happens from time to time both at home and abroad. Especially in China, the situation of stealing oil is very serious. The oil pipelines are located in many places, and some places are very remote and desolate. Oil thieves often choose such places to drill through pipelines to steal oil. Due to its remote and desolate location, it is difficult for oil field guards to find it. Therefore, a large amount of crude oil is stolen and leaked, causing huge losses to the country and enterprises. Even when oil field security personnel find oil stealing points, they often fail to catch the oil s...
