Description
Technical field
The utility model relates to a kind of waste gas sampling determination utensil, specifically a kind of special sampling box measured for oxides of nitrogen in stationary pollution source discharging waste gas.
Background technology
The mensuration hydrochloride naphthodiamide spectrophotometric method of oxides of nitrogen " in the Concentration in Fixed Pollutants Source " (HJ/T43-1999) is applicable to the state environment protecting standard that oxides of nitrogen that stationary pollution source discharges in a organized way measures.The Method And Principle of this standard is: oxides of nitrogen (NO
x) comprise nitrogen monoxide (NO) and nitrogen dioxide (NO
2) etc., when sampling, first the low oxides such as the nitrogen monoxide in gas are oxidized to nitrogen dioxide by chromium trioxide, after nitrogen dioxide is absorbed by liquid absorption, generate nitrous acid and nitric acid, wherein nitrous acid and sulfanilic acid play diazo-reaction, again with hydrochloride naphthodiamide coupling, in rose, according to shade, use spectrophotometry.
The method to the requirement of sample is: the porous plate absorption bottle that series connection one is empty in order, an oxidation tube and two porous plate absorption bottles respectively filling 75mL absorbing liquids are as absorption of sample device, accessed sampling system, and be positioned in ice bath, with the flow of 0.05 ~ 0.2L/min; Gas production to the second absorption bottle is blush, stops sampling.Record sampling flow, time, temperature, air pressure, sealing absorption bottle import and export, lucifuge transports laboratory back.
Sample collection because of this project has comparatively strict environment temperature requirement, and in sampling system, be in series with more easily worn part, the utensil of the splendid attire sampling instrument that current each environmental monitoring mechanism is all unfixing when sampling, or directly sampling instrument is spread in the Plastic Drum that ice cube is housed, therefore there is following problem: because of the more and sampling location complicated condition of series components, absorption tube is fragile; Ice cube needed for ice bath is produced and is incubated all inconveniences, is difficult to the temperature stabilization ensureing to measure environment, thus affects measurement result; And it is unordered to adopt various forms of bucket ice bath to make the sampling instruments such as absorption tube place, absorption tube is fragile; Have have employed ice bath but lucifuge condition can not meet; The micro-red judgement of second absorption bottle not easily; Some use can be placed the special sampling box sampling of absorption tube but can not be met condition of ice bath; Anti-absorbing liquid suck-back is made sometimes because absorption tube connects, etc.Cause sampling not meet code requirement, or cause resampling because absorption tube damages.Do not meet the special sampling apparatus of above-mentioned standard-required at present on the market.
