Abstract
A kind of sampling head for the sampling of stationary source low concentrations of particulates thing, including filter cylinder torr, at the embedded filter cylinder that is cased with of filter cylinder torr, described filter cylinder torr is tightly connected with sampling mouth by aluminium foil circle.Filter cylinder torr is tightly connected by the sampling head of the present invention with sampling mouth so that it is be integrally formed, and integrally weighs sampling head when weighing, it is to avoid the sampling impact on measurement result for the mouth sweep, measurement result is more accurate.
Description
Technical field
The present invention relates to a kind of sampling head for the sampling of stationary source low concentrations of particulates thing, it is adaptable to filter cylinder is sampled,
Belong to field of environment protection.
Background technology
In traditional sampling field, the filter cylinder for the particulate matter of the low concentration of stationary source is sampled, and typically takes
It is all the form that sampling mouth separates with filter cylinder torr, during weighing, only the filter cylinder in filter cylinder torr is weighed.But in the mistake of sampling
Cheng Zhong, has sample segment and is deposited in the sweep of sampling head, cause the error of weighing result, it could even be possible to there are data
Mistake, causes measurement result inaccurate.Accordingly, it would be desirable to existing structure is further improved.
Content of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide a kind of low for stationary source
The sampling head of concentration of particles thing sampling, by being tightly connected filter cylinder torr with sampling mouth, is integrally formed, decreases error so that it is
Measurement result is more accurate.
For solving above-mentioned technical problem, the technical scheme is that, a kind of for stationary source low concentrations of particulates thing
The sampling head of sampling, including filter cylinder torr, at the embedded filter cylinder that is cased with of filter cylinder torr, described filter cylinder torr is sealed with sampling mouth by aluminium foil circle
Connect.
Optimizing, described filter cylinder torr is hollow structure, is provided with rib in filter cylinder torr.
Optimize, rib or sampling mouth are provided with bar code or digital coding.
Optimizing, described sampling mouth includes arc sections, and arc sections is connected with vertical tube part by transition arc, at vertical tube part
Rear end be provided with filter cylinder torr adaptation compressed part.
The invention has the beneficial effects as follows, filter cylinder torr is tightly connected by the sampling head of the present invention with sampling mouth so that it is become one
Body, integrally weighs sampling head when weighing, it is to avoid the sampling impact on measurement result for the mouth sweep, measurement result is more accurate
Really.
Brief description
Fig. 1 is the structural representation of the sampling head for the sampling of stationary source low concentrations of particulates thing of the present invention.
Detailed description of the invention
The present invention will be further described in detail with embodiment below in conjunction with the accompanying drawings；
As it is shown in figure 1, a kind of sampling head for the sampling of stationary source low concentrations of particulates thing, including filter cylinder torr 1, in filter cylinder torr
The 1 embedded filter cylinder 2 that is cased with, described filter cylinder torr 1 is tightly connected with sampling mouth 4 by aluminium foil circle 3.Described filter cylinder torr 1 is hollow structure,
Filter cylinder torr 1 is provided with rib 5.Rib 5 is provided with bar code 6 or digital coding 7, naturally it is also possible at sampling mouth 4
On be provided with bar code 6 or digital coding 7.Described sampling mouth 4 includes arc sections 8, and arc sections 8 passes through transition arc and vertical tube part
9 are connected, and are provided with the compressed part 10 with filter cylinder torr 1 adaptation in the rear end of vertical tube part 9.
During use, filter cylinder 2 is positioned in filter cylinder torr 1, the compressed part 10 of sampling mouth 4 is positioned over filter cylinder torr 1 simultaneously
Opening part compresses, and uses aluminium foil circle 3 to be tightly connected sampling mouth 4 with filter cylinder torr 1, it is to avoid ectocine, improves certainty of measurement.
Filter cylinder torr is tightly connected by the sampling head of the present invention with sampling mouth so that it is be integrally formed, and integrally weighs when weighing
Sampling head, it is to avoid the sampling impact on measurement result for the mouth sweep, measurement result is more accurate.Carry out through researcher
The sampling head of the sampling head of the present invention and traditional separate type is carried out contrast test by dependence test, and certainty of measurement improves 5%-
8%, and then preferably ensure that the accuracy of sampling.
As described above, we are illustrated fully according to spirit of the invention, but the present invention is not limited to above-mentioned reality
Execute example and implementation.The practitioner of correlative technology field can carry out different in the range of the technological thought of the present invention is permitted
Change and enforcement.
