Description
Technical field
This utility model relates to a kind of Duplicate Samples sampling gun for stationary source particulate matter, belongs to environmental monitoring technology
Field.
Background technology
During stationary source particle sampling, for making sampled result more true and reliable.GB-16157 requirement,
Requiring that spot sampling should gather Duplicate Samples, on-the-spot Duplicate Samples should be sampled in flue or chimney the most simultaneously.Adopt now Duplicate Samples
Common practice be to have the flue of two or more thief hatch, take two sampling guns to insert respectively, sample simultaneously
Way.But this way has several drawback, 1, sample collecting is by opium pipe difference, and the equal extraneous factor of operator's operation is done
Disturb, result in error, it is ensured that the reliability that Duplicate Samples does not gathers, 2, this way need two set sampling apparatus works simultaneously
Making, this most at least needs 4 to 6 personnel operation simultaneously.The most loaded down with trivial details confusion.Some sampling platform can be the most crowded, it is difficult to behaviour
Make.3, only one of which thief hatch on some sampled point, flue or chimney, it is impossible to meet the condition being inserted simultaneously into two sampling guns,
Duplicate Samples cannot be gathered.This is just difficult to ensure that the true and reliable property of sampled result.
Utility model content
Not enough for prior art, this utility model patent provides a kind of Duplicate Samples for stationary source particulate matter to adopt
Sample rifle, this sampling gun uses dual pathways design, can install two sampling heads simultaneously, and an opium pipe can be adopted by two paths simultaneously
Sample, completes the collection to Duplicate Samples, reduces operator, and improves the reliability of measurement result.
For solving above-mentioned technical problem, the technical scheme of this utility model patent is, a kind of for stationary source granule
The Duplicate Samples sampling gun of thing, including pikestaff, is provided with protection pipe in the upper end of pikestaff, and protection pipe extends forward, before protection pipe
Being provided with pitot tube, pitot tube is connected with connecting tube, and connecting tube extends to pikestaff rear end, is respectively provided with in the both sides of pitot tube
There are the first sample introduction road, the second sample introduction road；First sample introduction road, the second sample introduction road are respectively by the pressure pipe arranged at supporting bracket and sampling
Head is connected.
Optimizing, the front end of described protection pipe is provided with platinum resistance, and platinum resistance is provided with platinum resistance protection pipe.
Optimize, be provided with pitot tube protection set in the front end of pitot tube.
Optimize, between pitot tube and supporting bracket, be provided with fixing pipe.
Optimizing, be additionally provided with air plug in the rear end of pikestaff, air plug electrically connects with platinum resistance.
The beneficial effects of the utility model are, sampling gun of the present utility model uses dual pathways design, can install simultaneously
Two sampling heads, an opium pipe can be sampled by two paths simultaneously, completes the collection to Duplicate Samples, improves the accurate of sampling
Property, reduce operator, and improve the reliability of measurement result.
Accompanying drawing explanation
The utility model is described in more detail with embodiment below in conjunction with the accompanying drawings；
Fig. 1 is this utility model main TV structure schematic diagram for the Duplicate Samples sampling gun of stationary source particulate matter；
Fig. 2 is this utility model plan structure figure for the Duplicate Samples sampling gun of stationary source particulate matter.
Detailed description of the invention
As shown in Figure 1, 2, a kind of Duplicate Samples sampling gun for stationary source particulate matter, including pikestaff 1, at pikestaff 1
Upper end be provided with protection pipe 2, protection pipe 2 extends forward, is provided with pitot tube 3 before protection pipe 2, pitot tube 3 and connecting tube 4
Being connected, connecting tube 4 extends to pikestaff 1 rear end, is respectively arranged with the 5, second sample introduction road, the first sample introduction road in the both sides of pitot tube 3
6；First the 5, second sample introduction road 6, sample introduction road is connected with sampling head 9 by the pressure pipe 8 arranged at supporting bracket 7 respectively.Described protection
The front end of pipe 2 is provided with platinum resistance 10, and platinum resistance 10 is provided with platinum resistance protection pipe 11.It is provided with in the front end of pitot tube 3
Pitot tube protection set 12.
Fixing pipe 13 it is provided with between pitot tube 3 and supporting bracket 7.It is additionally provided with air plug 14, air plug in the rear end of pikestaff 1
14 electrically connect with platinum resistance 10.
Duplicate Samples sampling gun for stationary source particulate matter of the present utility model, this sampling gun uses the dual pathways to set
Meter, can install two sampling heads simultaneously, and an opium pipe can be sampled by two paths simultaneously, completes the collection to Duplicate Samples, reduces
Operator, and improve the reliability of measurement result.When Parallel Sampling, original 4-6 people it is reduced to 2-3 people, Ren Yuan great
Big minimizing, decreases the spending of funds.Carry out dependence test through research worker, by of the present utility model for fixing dirt simultaneously
The Duplicate Samples sampling gun of dye source particulate matter and traditional two sampling guns obtain mode and carry out contrast test, and it is left that accuracy of detection improves 5%
The right side, in the case of reducing the personnel to operate, the biggest effect that improve detection.
As it has been described above, we are illustrated fully according to objective of the present utility model, but this utility model not limits to
In above-described embodiment and implementation.The scope that the practitioner of correlative technology field can permit at technological thought of the present utility model
Inside carry out different changes and enforcement.
