Description
Technical field
The present invention relates to a kind of atmosphere sampler field, more particularly to it is a kind of it is safe, prevent spontaneous combustion with it is anti-from
Fire the atmospheric sampling equipment of function.
Background technology
Atmospheric sampling is the process for gathering pollutant sample or contaminated air sample in air.Spot sampling method has two
Class：One class is to make large quantity of air by liquid-absorbant or solid absorbent, and the relatively low enriching pollutants of concentration in air are risen
Come, such as degassing method, filter membrane method.Another kind of is to gather the air containing pollutant with container (vial, polybag etc.).The former surveys
What is obtained is the mean concentration of pollutant in air in the sampling time；What the latter measured is instantaneous concentration or average dense in the short time
Degree.Depending on the mode of sampling should be according to the purpose of sampling and field condition.Institute's sample thief should be representative.Sampling efficiency is high,
Operation must be easy, and is convenient for subsequent analysis measure, to obtain the master data of reliable atmosphere pollution.Collection air
The sample of middle pollutant or the sample of contaminated air, to obtain the master data of atmosphere pollution.
Atmospheric sampling is the important step of atmosphere environment supervision, and the reliable sexual intercourse for Monitoring Data is very big.Collection is big
The method of gas sample product, mainly there is two classes:One class is to make large quantity of air by liquid-absorbant or solid absorbent, to absorb or hinder
Pollutant is stayed, the relatively low enriching pollutants of concentration in original air are got up, such as degassing method, filter membrane method.Measured with this kind of method
Result be pollutant in air in the sampling time mean concentration.Another kind of is with container (vial, polybag, rubber ball
Courage, syringe etc.) air of the collection containing pollutant.This kind of method is applied to following situations：In air the concentration of pollutant compared with
It is high；Or the sensitivity of assay method is higher；It is difficult by the dusty gas and steaming of liquid-absorbant absorption or solid absorbent absorption
Vapour.The result measured with this method is the instantaneous concentration or the mean concentration in the short time of pollutant in air.Additionally, also low temperature
Freezing, can be used to gather escaping gas and steam, such as alkyl lead.Liquid-absorbant in sampler is mainly used in absorbing gas
State and steam-like material.Conventional absorbent has：Water, compound water solution, organic solvent etc..Absorbent must be able to and pollutant
There is quickly chemical reaction or pollutant can be promptly dissolved, and be convenient for analysis operation.Such as fluorination in air
Hydrogen, hydrogen chloride are with water as absorbent；Sulfur dioxide can be with tetrachloro mercury sodium as absorbent；Thimet (3911), demeton
Etc. (1059) organophosphorus pesticide can be with 5% methyl alcohol as absorbent etc..Solid absorbent has granular adsorbent and threadiness to inhale
Attached dose two kinds.Conventional granular adsorbent has silica gel, unglazed pottery etc., for the sampling of gaseous state, steam-like and particulate matter.Fiber
Shape adsorbent has filter paper, filter membrane, absorbent cotton, mineral wool etc., and suction-operated is mainly physical detention, for gathering particle
Thing.Sometimes adsorbent makes pollutant chemical action occur with it and be adsorbed first with certain chemical reagent impregnation process, main to use
In collection gaseous state or steam-like pollutant.
Atmospheric sampling will select suitable sample mode according to the purpose of sampling and field condition.As continuously or instantaneously adopted
Sample, on ground, grab sampling or flowing sampling, are sampled in the air with balloon, aircraft, and Environment features, indoor sampling and dirt
Dye source sampling etc..Sampling purpose is different with sample mode, and the method for sampling and sampler used is also different.Such as in chimney
Grain thing sampling, can select appropriate location punching according to chimney shape, height, and the collector of sampler is stretched into hole, with etc. it is dynamic
The pumping collection of power speed.This method is referred to as isokinetic sampling method.
The sample that atmospheric sampling is gathered should be representative.The efficiency of sampling will height, operation must be easy, and be easy into
The subsequent chemical analysis of row is determined.The representational factor of influence sample has the efficiency of sampler and absorbent, the position of sampled point
Put with sampler to interference of air-flow etc..
In recent years, atmospheric sampling technology just gradually combines with analysis and testing technology, and constituting one kind can be continuously automatic
Sampled, analyze measure, record measured result device.This device can directly carry out field monitoring, referred to as monitoring point
Analyzer.
Air sampler plays a good role for the detection of pernicious gas in air and environment.With science skill
The continuous progress of art, air sampler is also constantly to release new product, such as：It is intelligent type atmospheric sampler, explosion-proof air sampler, double
Gas circuit air sampler etc. product, has greatly enriched the classification of air sampler.
However, air sampler is in sampling process, equipment generation is not within minority from the situation of dieseling, if equipment
Generation dieseling, then do not cause singly sampling to fail, and returns equipment and brings destructive damage in itself, and What is more also results in more
Big fire incident, consequence is hardly imaginable.Sample devices occurs what dieseling was much caused because heater temperature is too high,
It is therefore desirable to cause spontaneous combustion to prevent heater temperature too high, design a kind of atmospheric sampling with anti-spontaneous combustion function and set
It is standby.
