Abstract

The invention provides a reflective-type laser natural gas leakage detection device which comprises a structure installing machine frame, a laser transmitting-receiving machine, a laser reflecting plate correspondingly matched with the laser transmitting-receiving machine and a detection host machine arranged in a safety control center room, wherein the laser transmitting-receiving machine and the laser reflecting plate are installed on the edge of the top face of a natural gas detection region through the structure installing machine frame. The laser transmitting-receiving machine further comprises a first collimator and a second collimator located on a laser transmitting and laser receiving optical paths. The detection host machine comprise a laser excitation module, an optical signal output interface, an optical signal input interface and a spectrum analysis module, and the laser transmitting-receiving machine is connected with an optical signal output and input interfaces of the detection host machine through optical cables. The reflective-type laser natural gas leakage detection device is economic, easy to popularize and universally suitable for petroleum, chemical engineering, coal, energy resource transportation and other industries.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a reflective laser natural gas leakage detection device. Background technique [0002] LNG is the English abbreviation of liquefied natural gas (liquefied natural gas), the main component is liquefied methane, the volume ratio of its volume to gas methane is about 1:600, but its weight is only about 45% of the same volume of water, so it is widely used in Urban pipeline network, wharf long transportation (storing LNG in super-large LNG gas storage tanks and transporting by sea), etc. At the same time, many petrochemical plants have production rooms dedicated to the production of LNG. [0003] In recent years, infrared gas detection technology has been applied in natural gas transportation, transit and processing to detect the leakage of natural gas. At present, the remote leakage detection methods for liquid transportation such as crude oil, refined oil and urban groundwat...
