Description
Technical field
The utility model belongs to air sampling rig technical field of structures；Particularly relate to a kind of atmospheric sampling dress
Put.
Background technology
Atmospheric sampling is the process for gathering pollutant sample or contaminated air sample in air；As a rule acquisition method
There are two classes：One class is to make large quantity of air by liquid-absorbant or solid absorbent, and the relatively low pollutant of concentration in air is rich
Collection gets up, such as degassing method, filter membrane method；Another kind of is to use container（Vial, polybag etc.）Gather the air containing pollutant；Before
What person measured is the mean concentration of pollutant in air in the sampling time；What the latter measured is instantaneous concentration or flat in the short time
Equal concentration；The mode of sampling should be depending on the purpose and field condition according to sampling；Institute's sample thief should be representative；Use at present
Sampling absorption plant, is required to pump and is correctly connected with gas outlet, once connection error, it will suck the absorbing liquid in absorption tube
In pump, cause pump to damage, in practical operation, especially in experimental teaching, student often connects error, cause to break down than absorbing
The more expensive constant flow pump of device price；In addition, traditional atmosphere sampler can not carry out particle to identical sample gas simultaneously
The collection of thing, it is impossible to effectively analyze the relation between the particulate matter of identical sample air and dusty gas parameter.
The content of the invention
Goal of the invention of the present utility model：
Primarily to provide a kind of atmosphere sampler of brand new, effectively avoid in teaching Process of experiment by
The damage problem of constant flow pump caused by student's maloperation, while can be to the progress of identical sample gas during experiment
The collection of grain thing, effectively analyzes the relation between the particulate matter of identical sample air and dusty gas parameter；Improve experiment religion
Device functionality and practicality.
The technical solution of the utility model is：
There is provided a kind of atmosphere sampler, the atmosphere sampler is main by two symmetrical and structure identical left sides
Sampling body and right sampling body composition, symmetrical air inlet is provided with the top of left sampling body and right sampling body
Interchangeable is used between gas outlet, and air inlet and gas outlet；Buffering pipeline section is connected with below air inlet and gas outlet,
The bottom of buffering pipeline section is gradually reduced to be connected and in being wholely set with absorbing pipeline section, the bottom of absorption pipeline section be gradually reduced and with
Left sampling body is connected communicating pipe with what right sampling body bottom was set；In left sampling body and the air inlet of right sampling body
With gas outlet respectively with being additionally provided with the bottle stopper being mutually matched with separator tube at buffering pipeline section link position.
The length of described buffering pipeline section is 40mm~80mm；Internal diameter is 60mm~100mm.
The length of described absorption pipeline section is 60~100mm, and internal diameter is 12~24mm；And be provided with extraction duct
5ml graduation marks and 10ml graduation marks；Also served as a contrast in the bottom for absorbing pipeline section and be connected to bubbling plate.
The internal diameter of described communicating pipe is 1.4mm, to avoid fractureing, it is also possible to the flexible pipe connection of identical caliber, is preferably
Rubber hose.
It is also internal at the lower end position of separator tube to be lined with air-permeative filter plate.
Described left sampling body and the material of right sampling body are hard glass.
The beneficial effects of the utility model are：
The atmosphere sampler of the structure setting, is effectively avoided in teaching Process of experiment because student's maloperation causes
Constant flow pump damage problem, while during experiment can to identical sample gas carry out particulate matter collection, effectively
The identical sample air of analysis particulate matter and dusty gas parameter between relation；Improve experimental teaching device functionality and
Practicality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure；1 is left sampling body；2 be right sampling body；3 be air inlet；4 be gas outlet；5 be buffering pipeline section；6 are
Absorb pipeline section；7 be communicating pipe；8 be bottle stopper；9 be 5ml graduation marks；10 be 10ml graduation marks；11 be bubbling plate；12 be to breathe freely
Filter plate.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1 there is provided a kind of atmosphere sampler, the atmosphere sampler is main by two symmetrical and knots
The left sampling body 1 of structure identical and right sampling body 2 are constituted, and are provided with mutually on the top of left sampling body and right sampling body
Symmetrical air inlet 3 and gas outlet 4, and interchangeable is used between air inlet and gas outlet；Lower section in air inlet and gas outlet
Buffering pipeline section 5 is connected with, the bottom of buffering pipeline section, which is gradually reduced, to be connected with absorption pipeline section 6 and in being wholely set, absorb pipeline section
Bottom be gradually reduced and with it is left sampling body and right sampling body bottom set be connected communicating pipe 7；In left sampling body
It is mutually matched respectively with being additionally provided with buffering pipeline section link position with separator tube with the air inlet of right sampling body and gas outlet
Bottle stopper 8.
The length of described buffering pipeline section is 40mm~80mm；Internal diameter is 60mm~100mm.
The length of described absorption pipeline section is 60~100mm, and internal diameter is 12~24mm；And be provided with extraction duct
