Abstract
The utility model provides a perpendicular rifle head low concentration sample thief, includes the opium pipe handle, is provided with the sampling rifle at the front end of opium pipe handle, and the sampling rifle is including the sampling rifle body and sampling rifle head, and the internal length direction along the rifle body of sampling rifle is provided with exhaust tube, pitot tube and protective case, and exhaust tube, pitot tube set up in protective case's diameter inboardly, and be close to rifle head department at protective case and still be provided with temperature sensor, the sampling rifle body and perpendicular setting of sampling rifle head, sampling rifle head is including setting up in the sampling mouth of sampling rifle head bottom, and sampling mouth upper portion is provided with sampling mouth gland, is provided with seal ring in sampling mouth gland, and sampling mouth gland upper portion is provided with the catch tray. The utility model discloses a sampling head is perpendicular with body of a gun exhaust tube, has shortened sampling mouth length, has alleviateed sampling mouth weight. Simultaneously owing to adopt the straight peen sampling pipe, the contraction in length, the area that the pollutant was infected with to inside is littleer, and measuring result is more accurate.
Description
Technical field
The utility model relates to a kind of vertical rifle head low-concentration sampling device, belongs to environmental monitoring technology field.
Background technology
In to pollution source in flue dust and flue gas environmental monitoring, wherein fume/smoke monitor is often used by environmental monitoring mechanism.Fume/smoke monitor is mainly to the sampling of the dynamic pressure of flue, static pressure, flue-gas temperature, water capacity, oxygen level, gaseous contaminant (as: SO2, CO, CO2 etc.) measurement of concetration and particulate pollutant.But current existing sampling gun is in measuring process, most sampling pipe rifle head and the body of a gun all be arranged in parallel, thus sampling mouth length increases, and cause the long weight of sampling mouth to increase, and have impact on the precision of sampling.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of vertical rifle head low-concentration sampling device, and sampling head is vertical with body of a gun exhaust tube, shortens sampling mouth length, alleviates sampling mouth weight.Simultaneously owing to adopting straight peen sampling pipe, contraction in length, the area of inner pollutants is less, and measurement result is more accurate.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of vertical rifle head low-concentration sampling device, comprise opium pipe handle, the front end of opium pipe handle is provided with sampling gun, sampling gun comprises sampling gun rifle body and sampling gun rifle head, length direction along rifle body in sampling gun rifle body is provided with exhaust tube, pitot tube and protective casing, exhaust tube, pitot tube is arranged at inside the diameter of protective casing, also temperature sensor is provided with near rifle head place at protective casing, described sampling gun rifle body is vertical with sampling gun rifle head to be arranged, sampling gun rifle head comprises the sampling mouth be arranged at bottom sampling gun rifle head, sampling mouth top is provided with sampling mouth gland, packing washer is provided with in sampling mouth gland, sampling mouth gland top is provided with catch tray.
Optimize, described sampling mouth comprises a straight peen sampling pipe, is disposed with filter membrane, stainless steel holder net and sealing aluminium foil in the outside of straight peen sampling pipe along sampling mouth opening direction.
The beneficial effects of the utility model are, because the utility model sampling gun rifle head direction is vertical with rifle body, during sampling, rifle head is just to airflow direction.Directly adopt straight peen sampling pipe simultaneously and eliminate bend loss, only having now very short straight length.Have several benefit like this: 1 shortens sampling pipe length, and the area that pollutant is infected with is less, pollutant is less, and sampled result is just more accurate.2 low-concentration sampling mouth overall weight alleviate.Can weigh with the higher balance of precision, weighing also just more accurate.3, the pollutant be infected with due to straight peen sampling pipe is little, so can overallly weigh when weighing, only weighs filter membrane and is also fine.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in more detail;
A kind of vertical rifle head low-concentration sampling device, comprise opium pipe handle 1, the front end of opium pipe handle 1 is provided with sampling gun 2, sampling gun 2 comprises sampling gun rifle body 3 and sampling gun rifle head 4, length direction along rifle body in sampling gun rifle body 3 is provided with exhaust tube 5, pitot tube 6 and protective casing 7, exhaust tube 5, pitot tube 6 is arranged at inside the diameter of protective casing 7, temperature sensor 8 is also provided with near rifle head place at protective casing 7, described sampling gun rifle body 3 is vertical with sampling gun rifle head 4 to be arranged, sampling gun rifle head 4 comprises the sampling mouth 41 be arranged at bottom sampling gun rifle head 4, sampling mouth 41 top is provided with sampling mouth gland 42, packing washer 43 is provided with in sampling mouth gland 42, sampling mouth gland 42 top is provided with catch tray 44.
Optimize, described sampling mouth 41 comprises a straight peen sampling pipe 411, is disposed with filter membrane 422, stainless steel holder net 423 and sealing aluminium foil 424 in the outside of straight peen sampling pipe 411 along sampling mouth 41 opening direction.
Low-concentration sampling device improvements of the present utility model are embodied in 2 points: the first sampling gun rifle head direction is vertical with rifle body.During sampling, rifle head is just to airflow direction.The second, straight peen sampling pipe eliminates bend loss, only has now very short straight length.Have several benefit like this: 1 shortens sampling pipe length, and the area that pollutant is infected with is less, pollutant is less, and sampled result is just more accurate.2 low-concentration sampling mouth overall weight alleviate.Can weigh with the higher balance of precision, weighing also just more accurate.3, the pollutant be infected with due to straight peen sampling pipe is little, so can overallly weigh when weighing, only weighs filter membrane and is also fine.
As shown in Figure 1,2,3, 4, sampling head of the present utility model is vertical with body of a gun exhaust tube, and mouth of sampling like this becomes present straight tube from original bend pipe, shortens sampling mouth length, alleviates sampling mouth weight.Simultaneously due to contraction in length, the area of inner pollutants is less, and measurement result is more accurate.
As mentioned above, we are illustrated according to aim of the present utility model completely, but the utility model is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present utility model.
