Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Embodiment: the useless admittedly flue gas on-line monitoring analytical equipment of present embodiment; Shown in accompanying drawing 1; Mainly comprise the sampling unit, pretreatment unit, analytic unit, demarcation unit, purging unit and the data processing unit that connect successively; It mainly improves is before analytic unit, to be provided with pressure transducer, and analytic unit comprises FTIR infrared spectrum analyser and zirconia sensor.The FTIR infrared spectrum analyser is analyzed NO, the NO in the flue gas
2, CO, CO
2, HCL, SO
2Deng gas; Zirconia sensor can at high temperature detect the O in the flue gas
2Content.Flue gas is introduced into the FTIR infrared spectrum analyser, and the zirconia sensor of flowing through is then measured O
2Content.For monitoring flue stopping state, before advancing analytic unit, pressure transducer is housed, can also compensate the analyser data according to force value.
Present embodiment FTIR analyser adopts the DigiTectTM detector system; Detecting element, signal amplifier and 24 s' A/D converter is integrated; Directly the output digital signal does not need simulating signal in transmission course, to decay, and further reduces electronic noise; 24 A/D converters have then improved an one magnitude with the Testing of Feeble Signals ability of system.
The oxygen analysis adopts the zirconia sensor high temperature that these those skilled in the art knew to measure O down
2Concentration has reduced that the required condensation of general appearance gas dewaters, filtering process, provides cost savings.
Sampling unit generally is made up of sampling probe and trace pipe, blowback case.The fore filter of probe is the sintering metal filter core, and filtering accuracy is high, good permeability, and physical strength is high, and stock utilization is high, at high temperature can normally use, and is furnished with ceramic element in addition in a probe inside, and the double medium filtration mode is effectively to dedusting; And be furnished with heating element, prevent condensation of gas.Trace pipe power is big, heating is fast, insulation is good, has guaranteed the transmission that can can't harm, no dead angle of appearance gas.Work reliably and with long-term in order to guarantee to pop one's head in, the probe side is furnished with the blowback case and regularly probe is carried out blowback, reduces dust in the pipeline, prevents to stop up the road of taking a sample, and system's operation will be cleared up the pipeline of sampling probe after 1 year.
Pretreatment unit mainly comprises high-temperature cabinet, guarantees that appearance gas remains on 180 degree before advancing analytic unit always.In the high-temperature cabinet gas through 0.5 micron pot strainer and 0.1 micron spun glass two-stage filter after, obtain clean gas and get into the flue gas analysis unit.
