Abstract

The invention discloses an H2S gas ultraviolet spectrum detection device and an H2S gas ultraviolet spectrum detection method. The H2S gas ultraviolet spectrum detection device comprises an ultraviolet light source, a fiber collimating system, a long-path gas absorption tank, a fiber focusing system, an ultraviolet fiber spectrometer and a computer, wherein the ultraviolet light source is used foremitting ultraviolet light; the fiber collimating system is used for collimating the ultraviolet light and then enabling the ultraviolet light to enter the long-path gas absorption tank; the long-path gas absorption tank is used for reflating the incoming ultraviolet light for many times, then focusing the ultraviolet light to fiber by the fiber focusing system and transmitting the ultraviolet light to the ultraviolet fiber spectrometer by the fiber; the computer is used for receiving spectral data and calculating and storing the data. The H2S gas ultraviolet spectrum detection device combines an ultraviolet differential absorption spectrum detection technology and the long-path gas absorption tank for performing real-time online detection on H2S during oil exploration, power monitoring or environmental monitoring; the H2S gas ultraviolet spectrum detection method has the characteristics of high measurement accuracy, good stability, a simple structure, high integration, low cost and the like; the safe progression of construction can be promoted and thus the exploration and development benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of gas detection, in particular to a H 2 S gas ultraviolet spectrum detection device and method thereof. Background technique [0002] In petrochemical, environmental protection and power monitoring and other fields, H 2 S gas is a poisonous and harmful gas, and sometimes it will bring great safety hazards to the personal and property safety of the construction site. If these gases can be detected quickly, timely and accurately, it can provide guidance for taking safety measures on site, effectively eliminate potential safety hazards, and at the same time avoid environmental pollution caused by gases and affect environmental quality. [0003] Traditional gas detection usually uses electrochemical methods, which have shortcomings such as short service life, insufficient detection of gas types, high application costs, insufficient integration, low detection accuracy, and easy to be affected by on-site enviro...
