The service life for obtaining filter core is long, good filtration effect.
The purpose of this utility model can be realized by following technical proposal：
A kind of double filter cores applied to flue gas analyzer are popped one's head in, including probe body, for fixing the flange of probe body
Disk, the admission line connected with probe body are provided with the first filter core, the admission line on the air inlet of the probe body
Air inlet at be provided with the second filter core.
Preferably, the filter diameter of first filter core is 100~500um, the filter diameter of second filter core is 0.5~5um.
Preferably, the ring flange in " work " font construct, ring flange have the first connecting pin, second connection end and
Connecting pipe between the first connecting pin and second connection end, the first connecting pin connection probe body, described second
Pedestal is provided on connecting pin, the admission line is arranged in pedestal.
Preferably, second filter core is arranged in connecting pipe and the second filter core is coaxially disposed with connecting pipe.
Preferably, the diameter of second filter core is less than the internal diameter of connecting pipe, the second filter core and connecting pipe inner wall
Between gap form blowback path.
Preferably, being provided with blowback pipeline in the pedestal, the blowback pipeline is connected with the blowback path.
Preferably, being provided with the blowback hole being circular layout on the pedestal, the blowback hole connects the blowback pipeline
With blowback path.
The advantages of the utility model has simple in structure, good filtration effect, and filter core service life is long.

Specific embodiment
It is specific embodiment of the utility model and with reference to attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
See in figure, the utility model provides a kind of double filter cores applied to flue gas analyzer and pops one's head in, including a probe
Ontology 2, for fixing the ring flange 3 of probe body 2, the admission line 5 that is connected with probe body 2.When carrying out flue gas sampling, visit
Head ontology 2 is extend into the sampling such as chimney ground, and probe body 2 is fixed by ring flange 3, and flue gas is entered by probe body 2
And enter flue gas analyzer via admission line 5 and analyze.
Flue gas in industrial smoke, especially chimney, there are a large amount of dust, the clogging admission line 5 of dust in order to prevent,
The utility model is provided with the first filter core 1 at the air inlet of probe body 2, and the is provided at the air inlet of admission line 5
Two filter cores 6.Wherein the first filter core 1 is filtered as preliminary, filters out the major diameter dust in flue gas, and the second filter core 6 filters again,
Filter out the minor diameter dust for not allowing access into admission line 5.
In some embodiments, the filter diameter of the first filter core 1 is 100~500um, the filter diameter of second filter core 6 for 0.5~
5um。
Specifically, ring flange 3 is constructed in " work " font, ring flange 3 has the first connecting pin 3a and second connection end 3c, if
Put the connecting pipe 3b between the first connecting pin 3a and second connection end 3c.Wherein, 2 phase of the first connecting pin 3a and probe body
Even, pedestal is connected on second connection end 3c, admission line 5 is arranged in pedestal.Second filter core 6 is arranged in connecting pipe 3b
And it is coaxially disposed with connecting pipe 3b, the diameter of the second filter core 6 is less than the internal diameter of connecting pipe 3b, such second filter core, 6 He
Connecting pipe 3b, that is, spaced is for adsorbing powder dust on the surface of the second filter core 6.
When the utility model at work, flue gas first passes through the preliminary filtering of the first filter core 1, and the flue gas after preliminary filtering enters
Into probe body 2, entered in admission line 5 after the filtering again via the second filter core 6, and finally by admission line 5 into
Enter flue gas analyzer and carry out analysis detection.Due to the utility model before flue gas enters probe body 2 first by the first filter core 1 into
It has gone preliminary filtering, has greatly reduced into the flue gas in probe body 2 containing Dust Capacity, can effectively prevent sending out in probe body 2
Raw the problem of blocking, while also increase the service life of the second filter core 6.
With the increase of usage time, the Dust Capacity on the first filter core 1 and the second filter core 6 increases, and needs to remove the first filter
Dust on 1 and second filter core 6 of core, to ensure the filter effect of the first filter core 1 and the second filter core 6.The utility model is on the one hand
First filter core 1 and the second filter core 6 are purged by 5 reversed air inlet of admission line, blowback is on the other hand also provided on pedestal
Pipeline 4 further enhances blowback dynamics, enhances the purging effect of the first filter core 1 and the second filter core 6.
Specifically, the gap between connecting pipe 3b and the second filter core 6 constitutes blowback path 7, blowback pipeline 4 and blowback
Path 7 connects, and purge gas is entered on blowback path 7 by blowback pipeline 4 and the surface of second filter core 6 is purged, into one
Step removes the dust on the second filter core 6.
Further, being circular layout on pedestal has blowback hole (not shown), the blowback hole being circular layout and blowback road
Diameter 7 is corresponding, and purge gas enters blowback path 7 by blowback channel to be blown out via blowback hole, can ensure blowback road in this way
The blowback air pressure of 7 each position of diameter keeps stable and consistent with each other, and blowback effect is more preferable.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
