Natural gas pipeline leakage rapid detection system

Abstract

The invention relates to a natural gas pipeline leakage detection technology, in particular to a natural gas pipeline leakage rapid detection system. The natural gas pipeline leakage rapid detection system involves a gas collecting device, a gas conveying system and a carbon dioxide content detection device, wherein a cavity is formed in the gas collecting device, and a gas inlet hole and a firstgas outlet hole which communicate with the cavity are formed in the gas collecting device; an input end of the gas conveying system communicates with the gas inlet hole; and the carbon dioxide contentdetection device communicates with the first gas outlet hole. The system has the advantages of being reasonable and simple in structural design, safe, convenient, scientific and effective, capable ofrapidly judging the property of measured gas, and providing a scientific decision basis for emergency rescue work in the next step, the production cost is low, the installation is rapid and convenient, the flexibility is high, the carrying is convenient, the purity of the sample gas is high, and the detection result is accurate.

Description

technical field [0001] The invention relates to a natural gas pipeline leakage detection technology, in particular to a natural gas pipeline leakage rapid detection system. Background technique [0002] Long-distance natural gas pipelines pass through mountains, hills, plains, swamps and water networks. There are lakes, ponds, ditches and other waters along the pipeline. These waters are prone to generate methane. At present, during the daily inspection process, if bubbles are found in the waters that the pipeline passes through, the area needs to be excavated to further confirm that the natural gas pipeline is leaking. It is still the bubbles caused by biogas. This method of excavation confirmation is time-consuming and laborious, with high cost, long confirmation cycle, great safety hazards, and prone to secondary risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quick detection system for natural gas p...
