Description
Technical field
The present invention relates to environment measuring, and in particular to a kind of fume continuous automatic monitoring and control device.
Background technology
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 to use 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.In addition, also low temperature
Freezing, available for collection escaping gas and steam, such as alkyl lead.Wherein, should using the air sampler of filtrate choked flow method
The pollutant isolated with filter membrane in air, but existing this air sampler is in sampling process, it is also possible to occur particle
The phenomenon that thing is rebounded or blown away from filtrate, particularly in the case where sampling rate is big, particle readily penetrates through filter screen, not in filter
Online precipitation, these situations are all to cause the reason for collecting efficiency is relatively low.
The content of the invention
The present invention is in order to solve the above problems, it is therefore intended that provide a kind of fume continuous automatic monitoring and control device, it is to avoid
Above-mentioned the occurrence of, improve the degree of accuracy of particle collection.
The present invention is achieved through the following technical solutions：
A kind of fume continuous automatic monitoring and control device, including filtrate sampling folder, connector and support member, the filtrate
Sampling folder is connected on the upside of support member, and the connector is socketed in filtrate sampling folder and the junction of support member, the connection
Connected by soft material；The filtrate sampling folder is included inside joint chair circle, tight loop and interface, the joint chair circle from top to bottom
Set gradually the first filter membrane, supporting network；The interface is in bucket-shaped, and upper end and the joint chair circle lower end of interface pass through sealing trap splice grafting
Touch, the interface is with setting tight loop on the outside of the contact position of joint chair circle, the edge of the interface quarrel sets the second filter screen, institute
The middle part for stating interface quarrel sets the 3rd filter screen, and the bottom of the interface quarrel sets the 4th metafiltration net；The connector is round
The siphunculus of mesa-shaped, the larger one end of connector opening is sampled towards filtrate to be pressed from both sides, and the less one end that is open is connected towards support member
A circle connector guide rail is provided with tube wall on the inside of part, the lower end outside of filtrate sampling folder is provided with a circle and connector guide rail
The interface round platform of matching.
Air collector of the prior art, using filtrate gather air in aerosol particle thing be based on directly stop,
Inertial collision, diffusion precipitin, electrostatic attraction and gravitational settling etc. are acted on.Some filtrates based on interception, some filtrates with
Based on electrostatic attraction effect, the then several effects having occur simultaneously.The collecting efficiency of filtrate except having outside the Pass with self property, also with
The factors such as sample rate, the size of particulate matter are relevant.When low speed is sampled, based on diffusion precipitin, the collection to tiny particles content
Efficiency high；During high-speed sampling, acted on inertial collision based on, it is high to the collecting efficiency of larger particles.Size in air
Grain thing is simultaneously and deposited, when the timing of sample rate one, it is possible to which the particulate matter collecting efficiency for making a part of particle diameter small is relatively low.
In sampling process, it is also possible to occur the phenomenon that particulate matter is rebounded or blown away from filtrate, particularly in the big situation of sampling rate
Under, phenomenon that particle is big, the particle of quality weight easily rebounds；The small particle of particle is easily blown away through filtrate, and these situations are all
It is to cause the reason for collecting efficiency is relatively low.
The problem of present invention exists for above-mentioned air sampler is improved, and many metafiltration are set in filtrate sampling folder
Film, wherein, supporting network is provided with the downside of the first filter membrane, the particulate matter born its object is to the first filter membrane is most, particulate matter pair
The impact of first filter membrane is maximum, in order to prevent the first filter membrane from damaging, sets supporting network to be supported the first filter membrane；Second filter
Film, the 3rd filter membrane, the 4th filter membrane are from top to bottom set, and the particulate matter that it is intercepted is less and less from top to bottom, fewer and fewer, its
Purpose be by the first filter membrane be the particulate matter intercepted carry out second, third time, the 4th interception, it is ensured that in the wind passed through
The content of particulate matter be preferably minimized；The downside of joint chair circle is fitted with the upside of interface, and outside carries out locking admittedly using tight loop
Fixed, inner side is sealed using sealing ring, it is therefore intended that further strengthen the rate of tension of the first filter membrane and supporting network.
By the mutual cooperation of interface round platform and connector guide rail, filtrate sampling folder can be made to deviate vertical direction, and enclose
Junction around filtrate sampling folder and support member moves in a circle, in folder surrounding air that thus filtrate can be sampled
Grain thing collection is complete, is further ensured that the degree of accuracy of flue dust collection.
Further, the 3rd filter screen is in bucket-shaped, and its summit is fixed on the second filter screen, and its edge is fixed on the second filter screen
On interface inwall between the 4th filter screen.3rd filter screen uses bucket-shaped, and it is inclined, with certain angle to make the 3rd filter screen
, so make particulate matter will not be perpendicular through the 3rd filter screen, it is easier to be intercepted by filter screen.
Further, support member includes ventilation duct, shell, described ventilation duct one end connecting interface, and the other end is from shell
Upside enter in shell, and with setting pumping blower fan inside the housing be connected, the blower fan that is evacuated is also associated with flow
Recorder, the bottom of the shell is provided with a plurality of supporting leg, and the supporting leg lower end is provided with movable pulley, and the movable pulley is set
It is equipped with fixed buckle.Support member is easy to the movement and locking of harvester.
Further, it is spiral lamination inside ventilation duct.Ventilation duct is arranged to spiral lamination, can produce air a certain degree of
Whirlpool, it is ensured that the particulate matter for entering filtrate sampling folder reduces loss.
The present invention compared with prior art, has the following advantages and advantages：The present invention is in the collection of existing air
On the basis of device, filtrate sampling folder is improved, multistorey strainer mesh is provided with to filtrate folder, it is ensured that in the air passed through
Grain thing drops on filter screen, improves the degree of accuracy of gathered data.
