Description
Technical field
Blow device is the utility model is related to, specifically a kind of high effective flue gas sampling blow device.
Background technology
During smoke sampling, the sampled pipe of flue gas sample gas flow to filter core, and after filter element filtering, the dust in sample gas is left on
The inner side of filter core, after clean sample gas is by filter core, analyzer is sent to by exhaust tube.It is normal by continuous a period of time
After sampling, the inner surface of filter core can assemble increasing dust, so that the resistance of filter core becomes increasing, sample gas
Flowing is not smooth, therefore, it is necessary to carry out regular purge to filter core by existing blow device, existing blow device is in filter core
End easily forms purging dead angle, causes the end local stoppages of filter core, in addition, the purging air-flow of existing blow device and filter
The time of contact on in-core surface is shorter, and purging is not abundant enough.
Utility model content
To solve the above problems, the purpose of this utility model is, there is provided it is sufficiently a kind of high to reduce purging dead angle, purging
Imitate smoke sampling blow device.
The utility model to achieve the above object, is achieved through the following technical solutions：A kind of high effective flue gas sampling purging dress
Put, including filter cylinder, filter cylinder is interior to set filter core, and filter core one end connects probe tube, and the filter core other end connects the big of the anemostat of taper
Diameter end, the smaller diameter end of anemostat connect scavenging conduit, set magnetic valve on scavenging conduit, anemostat is set along axis on inwall
The deflector of several arcs, exhaust tube is connected on filter cylinder.
Further to realize the purpose of this utility model, following technical scheme can also be used：Described filter core interior edge length
Spend direction and two guide rods are installed, scraper plate is set in filter core, two pilot holes are opened up on scraper plate, guide rod is oriented to positioned at corresponding
In hole, the scraping ring of scraper plate periphery installation annular, scraping ring is touched with filter core inwall, and through hole is opened up on scraper plate.Described through hole is with taking
Sample pipe is coaxial, a diameter of D1 of probe tube, a diameter of D2 of through hole, D1 ＞ D2.Described scraper plate both sides set adsorption layer.
The utility model has the advantage of：When the utility model purges to filter core, purge solenoid valve is opened, pressure-air leads to
Scavenging conduit is crossed, into filter core inner surface, the dust gathered in filter core is taken away, and by probe tube blowback air-returen flue.Diffusion
Pipe is the flow pipe of a taper, and it enables pressure-air to spread, and directly impacts the inner surface of filter core, and it is dead to reduce purging
Area so that purging can be more abundant；Deflector is located in anemostat, and due to the guide functions of deflector, gas leaves diffusion
Guan Shi, spiral helicine stream condition is formed, when spiral helicine high pressure draught adds purging air-flow contact with filter core inner surface
Between, further enhance purging effect.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；Fig. 2 is the utility model another kind structural representation；Fig. 3 is Fig. 2 A
To enlarged drawing.
Embodiment
A kind of high effective flue gas samples blow device, including filter cylinder 8, and filter core 2, the connection sampling of the one end of filter core 2 are set in filter cylinder 8
Pipe 1, the larger diameter end of the anemostat 4 of the other end of filter core 2 connection taper, the smaller diameter end connection scavenging conduit 7 of anemostat 4, purging
Magnetic valve 6 is set on pipe 7, and anemostat 4 sets the deflector 5 of several arcs on inwall along axis, exhaust tube is connected on filter cylinder 8
3.Magnetic valve 6 is closed when smoke sampling samples.When being purged to filter core 2, purge solenoid valve 6 is opened, pressure-air passes through scavenging conduit
7, into the inner surface of filter core 2, the dust of accumulation in filter core 2 is taken away, and by the blowback air-returen flue of probe tube 1.Anemostat 4 is
The flow pipe of one taper, it enables pressure-air to spread, and directly impacts the inner surface of filter core 2, reduces purging dead band,
So that purging can be more abundant；Deflector 5 is located in anemostat 4, and due to the guide functions of deflector 5, gas leaves diffusion
During pipe 4, spiral helicine stream condition is formed, spiral helicine high pressure draught adds purging air-flow contact with the inner surface of filter core 2
Time, further enhance purging effect.
Two guide rods 9 are installed along its length in described filter core 2, scraper plate 10 is set in filter core 2, opened up on scraper plate 10
Two pilot holes 11, guide rod 9 are located in corresponding pilot hole 11, the scraping ring 12 of the periphery of scraper plate 10 installation annular, scraping ring 12 with
The inwall of filter core 2 is touched, and through hole 13 is opened up on scraper plate 10.This structure can be when purging 2 inner surface of filter core, and pressure-air passes through
Scavenging conduit 7 and anemostat 4, blow scraper plate 10 and the other end is moved to by the one end of filter core 2 along guide rod 9, in moving process, filter core 2
The dust of inner surface accumulation is scraped by the scraping ring 12 on scraper plate 10, and is blowed by pressure-air to probe tube 1.During smoke sampling,
Flue gas blows scraper plate 10 to the side of anemostat 4, avoids the filtering for hindering filter core 2 to flue gas.Scraping ring 12 is the knot such as bristle, cushion
