Flue gas flow channel includes inlet channel, sinking passage, rising passway and the outlet passageway being sequentially communicated；
Having the first baffle plate and second baffle in described sinking passage, the first baffle plate airtight connection is in the top of sinking passage Portion, second baffle airtight connection is in the bottom of sinking passage；
Wherein, described filtering head, sampling gun barrel and sampling gun hand rest are respectively provided with draw-in groove.
Preferably, described filtering head is hollow cylindrical structure.
Preferably, described filtering head is metal material.
Preferably, described rising passway has cushion chamber with the junction of outlet passageway.
Preferably, described first baffle plate and second baffle are and are obliquely installed.
Preferably, it is provided with collet outside described sampling gun hand rest.
Preferably, it also is provided with filter element inside described intervalve.
Preferably, described filter element is filter cotton or ceramic honey comb.
Preferably, described sampling gun barrel is metal material.
The invention has the beneficial effects as follows:
(1) by the design of screw thread pair with draw-in groove, so that this device critical piece can be dismantled, it is simple to reduce Length in a non-operative state, it is simple to carry.
(2) collet is set outside opium pipe, it is to avoid the generation of the situation that scalds one's hand.
(3) in filtering head, there is filter element, it is possible to achieve to the once filtration of flue dust in flue gas.
(4) there is filtration flue and the baffle plate of abnormity, it is achieved that the secondary filter of dust in flue gas in sampling opium pipe.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: one can assembling filter formula flue gas sampler, its structure as Figure 1-3, including:
Filtering head 1；Filtering head 1 is the hollow cylindrical structure of metal material, and diameter 3cm is about 5cm.
The right-hand member of filtering head 1 is removably connected by screw thread pair with the left end of sampling gun barrel 2, and the right-hand member of sampling gun barrel 2 leads to Crossing screw thread pair to removably connect with intervalve 4, intervalve 4 is removably connected with sampling gun hand rest 5 by screw thread pair；
The inside of described filtering head 1 and intervalve 4 is filled with filter element 15.According to different needs, filter element 15 Filter cotton or ceramic honey comb can be chosen as.When using ceramic honey comb, 30/cm of its hole count2。
Wherein, described filtering head 1, sampling gun barrel 2 and sampling gun hand rest 5 are respectively provided with draw-in groove 3, it is simple to use instrument is torn open Unload.
Described sampling gun barrel 2 is internal has flue gas flow channel；Sampling gun barrel 2 is hollow cylinder shape, and metal material is about 50cm, internal diameter is slightly larger than the external diameter of filtering head 1.
Flue gas flow channel includes inlet channel 8, sinking passage 9, rising passway 14 and the outlet passageway 13 being sequentially communicated.Air inlet Passage 8 connects with filtering head 1, and outlet passageway 13 connects with intervalve 4.
In the junction of rising passway 14 with outlet passageway 13, having cushion chamber 12, the bottom of cushion chamber 12 is less than giving vent to anger The bottom of passage 13.
There is in sinking passage 9 the first baffle plate 10 and second baffle 11 being obliquely installed, the first baffle plate 10 airtight connection in The top of sinking passage 9, second baffle 11 airtight connection is in the bottom of sinking passage.
It is provided with collet 6 outside described sampling gun hand rest 5.
Described sampling gun hand rest 5 is hollow cylinder shape, and metal material is about 40cm, and it is inducing QI that rear portion is contracted to diameter 1cm Pipe 5, connects airway by rubber tube or heating muff, then accesses detecting instrument or absorbing liquid carries out flue gas analysis.
The principle of the present invention is:
Scene utilizes spanner to block draw-in groove 3, then by filtering head 1 and sampling gun barrel 2 airtight connection, the most again by sampling gun Pipe 2 connects with intervalve 4, sampling gun hand rest 5 successively.
Containing the ash of flue dust, enter from left side, first pass around filtering head 1 and once filter.Flue gas after filtration, enters Inlet channel 8, is then directed to, and enters sinking passage 9.In sinking watching, part flue dust falls in sinking passage 9.With The flowing to the right of flue gas, part dust can be fallen by the first baffle plate 10 gear.Most flue gas is logical with sinking from the first baffle plate 10 When gap between bottom road is passed through, all can encounter second baffle 11.Second baffle 11 defines one with the bottom of sinking passage 9 Individual reverse draw-in groove, can accommodate flue dust, and prevent flue dust from rising.It follows that flue gas is through rising passway 14, buffered chamber 12 Final buffer falls after ash, flows out from outlet passageway 13.
After use, this device is dismantled folding and unfolding.Sampling flue dust within gun barrel 2, can directly be rushed by current Walk, can use standby next time after drying.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention. Multiple amendment to embodiment will be apparent from for those skilled in the art, as defined herein typically Principle can realize without departing from the spirit or scope of the present invention in other embodiments, is not described in detail The part presented with partial enlargement, for prior art, does not repeats at this.Therefore, the present invention is not intended to be limited to herein These shown embodiments, and it is to fit to the widest scope consistent with principles disclosed herein and feature.
