Multi-channel leakage monitoring method for buried tank area of gas station

Abstract

The invention relates to a multi-channel leakage monitoring method for a buried tank area of a gas station and mainly solves the problems of poor applicability, time conservation and labor conservation in the prior art. According to the multi-channel leakage monitoring method for the buried tank area of the gas station, a sample collected by at least one sampling pipe which is arranged in the buried tank area of the gas station flows through one of sample channels of a multi-way valve under the action of a sampling pump and then enters a photoionization combustible gas detector; when the detector detects that the content of volatile organic gas in the sample exceeds the lower sensitivity limit value of the photoionization combustible gas detector and exceeds the upper gas leakage amount setting limit value of a sampling point; a display alarm which is connected with the detector gives an alarm to prompt leakage. According to the technical scheme, the problems are better solved. The method can be applied to leakage monitoring of the buried tank area of the gas station.

Description

technical field [0001] The invention relates to a multi-channel leakage monitoring method for a buried tank area of ​​a gas station. Background technique [0002] With the continuous development and progress of society, people's awareness of environmental protection has been continuously enhanced, and people have begun to pay more and more attention to various environmental issues. Buried oil tanks buried in the ground for a long time will leak under the action of natural disasters such as earthquakes and corrosion. The EPA statistics of the US Environmental Protection Agency show that the average age of steel buried oil tanks is 17 years. If the leakage cannot be found in time, it will not only cause direct safety hazards and economic losses, but also pollute the soil and groundwater, thereby causing serious harm to the environment and human health. Therefore, it is necessary to strengthen the leakage monitoring of buried oil tanks and take effective measures to prevent le...
