Description
Technical field
The utility model relates to gas detect, particularly relates to in-situ type laser spectrum gas analyzing apparatus.
Background technology
Based on the laser gas analyzer of tunable diode laser absorption spectroscopy (TDLAS) technology, can be used for measuring O
2, CO, CO
2, CH
4, HCL, HF and NH
3deng gas.This analyser adopts vertical cavity surface emitting laser (VCSEL) or distributed feedback laser (DFB) as tunable laser source, by triangular wave or the tested gas absorption spectrum line of sawtooch sweep.By obtaining the optic spectrum line information that gas characteristic to be measured absorbs, thus the quantitative test carried out.
Laser gas analyzer adopts " single line spectrum " technology and laser wavelength scan technology to make TDLAS technology can be used to realize the in site measurement analysis of gas, possesses stronger environmental suitability than traditional sampling gas analysis systems such as Non-Dispersive Infra-red (NDIR).Laser gas analyzer based on TDLAS principle passes through in site measurement, without the need to the pretreatment system of complexity, there is measurement not by background gas cross jamming, not by the impact that dust and form pollute, the advantages such as fast response time, reliability are high, maintenance period is short and maintenance cost is low, improve the level that online process gas detects greatly.
Laser gas analyzer can adopt in site measurement mode, carries out measuring fast, accurately and reliably to tested gas content in sample gas component.But, if if the gas temperature of application scenario is too high, instrument internal temperature rise temperature can be made too high thus cause hardware circuit and laser instrument temperature control to occur extremely.
