Background technology
Atmosphere and exhaust emission (comprising gaseous contaminant, gasoloid etc.) monitoring all needs to draw the monitoring analysis result after sending lab analysis behind the spot sampling; And analysis result whether can accurately reflect the true pollution level of atmosphere quality true horizon and atmosphere pollution and spot sampling the time collecting efficiency of gaseous contaminant much relations are arranged, atmosphere and exhaust emission (such as tens of kinds of pollutants such as SO2, NOX, O3, H2S) analytic process mainly are on-the-spot with after the absorption liquid collection at present, send the laboratory by comparing quantitative from the typical curve of drawing afterwards with the standard solution analysis that contains serial different these materials of amount again; And this quantitative prerequisite when being spot sampling the collecting efficiency of exhaust emission be 100% could be accurately, namely on-the-spot exhaust emission collecting efficiency is more high more can accurately reflect the atmospheric pollution level.
Present on-the-spot exhaust emission collecting efficiency does not reach 100%, nearly all standard method of analysis to this content all without identifying, all without concrete atmosphere and exhaust emission collecting efficiency data, the analytical approach that has considers that the exhaust emission collecting efficiency may be on the low side and take simultaneously secondary to absorb and improved the exhaust emission collecting efficiency, and most of analytical approach remains one-level and absorbs.Therefore, present on-the-spot atmosphere and exhaust emission collecting efficiency are on the low side.The typical curve of most of GB analytical approachs is to get the standard substance that will carry out the quantitative test project disposes serial content behind accurate quantitative analysis standard solution, draw out typical curve with the standard solution of serial content through lab analysis again, the absorption liquid that relatively gathers behind atmosphere and the exhaust emission is determined monitoring result; Typical curve then is directly to come with the standard solution analysis that contains different amounts behind the accurate quantitative analysis, if coming the collecting efficiency of arbitrary concentration on the criterion curve by collecting efficiency is 100% certainly, it just should be wrong in theory that on-the-spot exhaust emission collecting efficiency does not reach 100%.Therefore, improving on-the-spot exhaust emission collecting efficiency is even more important to the accuracy that improves analysis result.
The spot sampling method of the regulations such as national standard analytical approach adopts the absorption tube (also being the general absorption tube of relevant industries basically at present) of regulation; Major part adds 10 milliliters to 50 milliliters of absorption liquids, and whole gaseous contaminant absorption or retardance process are bubble and rise to about about 5 to the 10 centimetres bubble uphill process of absorption liquid level by the absorption tube bottom.Such absorption process is difficult to reach 100% absorption efficiency.
