Description
Technical field
Gas detection technology field is the utility model is related to, more particularly to a kind of anti-gaseous state analyzer condensation and dewfall and is prevented
The device of dirt.
Background technology
Ambient air monitoring system is that one of degree of integration highest component units are automated in environmental monitoring, also shoulder
Bear the mission of live issue air quality online monitoring data.State's control point position of national air station at present has as many as 1436,
And quantity is also increasing year by year, under the conditions of special weather, in the prevalence of gaseous analytes instrument condensation and dewfall and dust-proof ask
Topic.
Gaseous analytes instrument includes SO in ambient air monitoring system2、O3、NO2With tetra- kinds of analyzers of CO.On the one hand, according to
《Surrounding air gaseous contaminant (SO2、NO2、O3, CO) continuous and automatic monitoring system technical requirements and detection method》(HJ 654-
2013) requirement in, in order to prevent from causing because of the difference of indoor and outdoor air temperature sampling total inside pipe wall condensation, so as to monitoring
Pollutant adsorbs, and typically installs muff or heater additional to sampling house steward (heating-up temperature general control is at 30~50 DEG C).But
On-line monitoring equipment to the temperature requirement of indoor environment between 15~35 DEG C, when the moisture content in sample is higher, Indoor Temperature
When degree is reduced to dew point, the phenomenon of condensation and dewfall will occur in analyzer sample lines.Especially during the broiling summer, indoor outer shroud
The border temperature difference is larger, and in the higher area of southern moisture content, condensation and dewfall phenomenon is more frequent, and technical staff is difficult accurate judgement
The design temperature of station air-conditioning.On the other hand, because gaseous analytes instrument is in analysis environments air during the sample of gaseous contaminant,
For the influence from particulate matter in sample, the pipeline upper installing hole footpath typically between analytical instrument and branch pipe connection is not more than
5 μm of teflon membrane filter removes the particulate matter in sample.If filter membrane, the sampling flow of analytical instrument can not be changed in time
Warning scope will be exceeded, so as to cause monitoring result distortion.Generally, technical staff needs to check filtering filter membrane weekly
Whether need to change, still, what it is due to existing selection is 47mm filter membranes, and contact area is small, in some heavily contaminated weather, especially
After sandstorm is passed by, changing the frequency of filter membrane can greatly increase, and for some remote websites, technical staff is difficult to enter in time
Row processing, and the defects of due to existing structure, technical staff is also difficult to intuitively find to filter whether filter membrane needs to change.
At present, humidity conditioner mainly includes following four classes dehumanization method from principle：(1) heating and dehumidification, it is current
The method that ambient air monitoring system most generally uses, it is that sampling house steward is heated using heater, makes the temperature of sample gas
Degree is higher than dew point, and installs muff additional in sampling house steward and bypass line, influence of the barrier indoor temperature to sample gas, avoids condensing
Condensation heats to sampling house steward；But the shortcomings that method is that linking parsing instrument is not entered with sampling the bypass line of house steward
Row heating, so being easy to form condensation and dewfall in branch road.(2) partial pressure differential dehumidifying, point of perfluoro sulfonic acid membrane both sides steam is utilized
Press it is different can produce pressure differential, the steam in the gas that measuring moisture is higher in film is passed through film, reach the effect of dehumidifying；This method
Although need not heat, effect on moisture extraction is vulnerable to the influence of the factors such as ambient temperature, and control is unstable, and cost is also higher, and
With highly acid, sample gas can be caused to be interfered, be unfavorable for being applied to the analysis of surrounding air.(3) silica dehydrator pipe dehumidifies, its
It is the water imbibition using silica gel, during airflow passes drying tube with steam, steam is spread by absorbed on silica gel to surrounding, and sample gas
Then enter instrument with air-flow, to reach the effect of dehumidifying；But in southern area, moisture content is larger, changes the frequency of silica gel
It will greatly increase, be insufficient for the demand of continuous on-line monitoring research.(4) dehumidification by condensation, the method are to pass through condensation and dewfall
Mode discharge steam in sample, when moisture content is higher, the method has higher value, suitable for existing ring
Border atmospheric monitoring system；But at present still it is untapped have according to this principle be used for gaseous analytes instrument dehumidifying utility model device,
Mainly still isolated plus the method for existing removal particulate matter using teflon membrane filter of the aperture no more than 5 μm, still
Many weak points in actual application also be present with reason, the methods such as existing structure defects because contact area is small, such as
Heavily contaminated weather changes frequency increasing etc..In summary, existing apparatus and method not can effectively solve the problem that gaseous analytes instrument is cold
Condense the problem of revealing and be dust-proof.
Therefore, design one kind is simple in construction, easy to loading and unloading, cost is cheap, the good anti-gaseous state analyzer condensation of using effect
Condensation and dust-proof device are significant.
