Description
Technical field
The utility model is related to a kind of environmental monitoring sample devices, and in particular to a kind of gas sampling gun.
Background technology
The smoke exhaust of factory chimney discharge is mostly that fuel combustion is produced, and these fuel are mainly coal, coke, Jiao
Coal etc..Their burning can all produce the waste gas such as dust, carbon dioxide and dust.These substances on human's lives and natural environment
Affect very big.Flue dust can increase in atmosphere " pellet " content, be not only harmful to human body, and descend slowly and lightly and can increase on the ground
Plus pollute, serious meeting causes " black sonw " phenomenon.Carbon dioxide is greenhouse gases, is damaged the ozone layer, and causes global warming, polar region
Intensification causes sea level to go up, and marine organisms are dead.Current different type enterprise, the Air Pollutants of enterprise's discharge are different,
In order to be clear from chimney Air Pollutants, its emission need to be analyzed, analysis is accomplished by sample it is necessary to the chimney
Emission carries out flue gas sampling.
Remove outside the effect of environmental protection supervision aspect, flue gas sampling is equally factory's boiler emission, equipment performance
The important step of test.For example, it is the smoke components of understanding thermal power plant denitrating system exhaust pass, so as to giving to denitrfying agent
Go out optimal proportioning and improve denitration efficiency (including the change of smoke components), will be in denitration device performance test (including de-
Nitre equipment performance check and accept and scrap build before and after performance test) in flue gas is sampled, and chemical analysis is carried out to sample.
Wherein, when sampling measuring point flue gas/flue dust in factory's smoke exhaust discharge process, need to be adopted using flue gas
Sample rifle, wherein, the gun barrel part of gas sampling gun is made up of stainless steel tube, and its pipette tips is inserted by the gaging hole on furnace wall or flue
In entering flue, then flue gas is pumped in absorption bottle by sampling pump carries out data analysis.
However, during flue gas/smoke dust sampling, often existing and cannot be sealed or poorly sealed between gaging hole and gun barrel
Problem.When gaging hole of the sampling gun gun barrel from furnace wall or flue inserts flue, also exist between the gun barrel and gaging hole of sampling gun
Gap, then now need to seal gaging hole, when especially air pressure opposite outer atmospheric pressure is negative pressure in flue, prevents
Air is impacted from gaging hole into the numerical value that flue is particularly oxygen amount to smoke components.And at present common practice is to utilize hair
Towel and other items blocks the gap from gaging hole surrounding, but the method not only complex operation, and the effect of towel plug-hole is not yet
Very well, this can not well solve the sealing problem of gaging hole, can still result in air excess in detection process and enter in the middle of flue,
Affect testing result.
