Description of drawings
Fig. 1 is the utility model flame photometric detector (FPD) structural representation;
Fig. 2 is the luminous and photometry parts sectional view of the utility model flame photometric detector (FPD).
Embodiment
For further setting forth the utility model flame photometric detector (FPD), do more detailed explanation below in conjunction with embodiment.
Fig. 1 is a novel flame photometric detector structural representation, and the utility model flame photometric detector (FPD) comprises heating arrangement A1, sampling device A2, luminous component A3, photometry parts A4 and auxiliary electrical components A5 five major parts.
Heating arrangement A1 installs 2 75W heating rod outsourcing high-quality heat-preservation cotton, and overall volume reduces, and heating rate is faster, and it is higher good to be incubated.Sampling device A2 directly inserts in the horizontal post case.Ignition part A3 is designed to twin-jet nozzle and has eliminated quenching effect.The photometry parts A4 of two symmetries can dismantle that photomultiplier transit light is changed optical filter and the organic compound of surveying phosphorous or sulphur respectively.
It in Fig. 2 the sectional view of luminous component and photometry parts.
The luminous component air directly enters outer nozzle 9 by air access 6, and hydrogen fully mixes after inner nozzle 10 enters the photometry parts by carrier gas access 8 by hydrogen access 7 and carrier gas, is lighted by portfire 3.Pressure dome presents outer fired state in the combustion flame periphery, has concurrently to be difficult for fire extinguishing and highly sensitive advantage.
The photometry parts mainly comprise quartz window 4, optical filter 2, lens 5 and photomultiplier 1, a cover in each photometry parts, and optical filter difference wherein is respectively and surveys phosphorus and survey the sulphur optical filter, and two cover photometry parts are finished the content detection to p and s simultaneously.
