Description
Technical field
The utility model belongs to air detection apparatus field, in particular to a kind of air pollutants detection device.
Background technique
Air pollutants are made by the mixture of gaseous material, volatile materials, half volatile substance and Atmospheric particulates
At, constituent makes a variation clearly.The composition of air pollutants is influenced by many factors, such as meteorological condition, daily
Different periods, different number of days weekly, industrial activity and high traffic degree etc. so that the composition of air pollutants is generated change
Change.And in air pollutants, the influence especially with Atmospheric particulates to human body is the most serious, therefore understands Atmospheric particulates in air
Content for grasp air quality have important references value.
Atmospheric particulates are the general names of various solid-states present in atmosphere and liquid particles shape substance.Various particulate materials
It is evenly dispersed in one metastable huge suspension system of composition, i.e. aerosol system, therefore airborne particulate in air
Object is also referred to as atmospheric aerosol.The detection mode of current atmospheric particulate matter mainly has gravimetric method, light scattering method, photometry
Deng, mainly in normal conditions detect per unit volume gas dust-laden weight, and then determine air in dust content, be
Judge that the quality of air lays the foundation.In the measurement method of a variety of Atmospheric particulates, gravimetric method because operate it is convenient and needed for set
It is standby relatively easy, therefore be widely used.In gravimetric method operating process, a pipeline mainly is utilized, in pipeline
Exhaust fan is arranged in one end, then filter paper or gauze are arranged in pipeline, carries out certain time to the atmosphere in air by exhaust fan
Extraction, determine atmosphere extract volume, then take out filter paper or gauze, filter paper or gauze be placed on the scale pan of assay balance
It is weighed, is compared by the weight to filter paper before and after dust or gauze, can determine dust weight.Although which
It is easy to operate, also there is certain indicative significance to the Atmospheric particulates content in atmosphere, but during atual detection, in atmosphere
Part Atmospheric particulates be attached in pipeline, and then the Atmospheric particulates content actually measured can be made relatively low vertically, it is unfavorable
In the detection of Atmospheric particulates content, the detection of entire air pollutants is adversely affected.
Utility model content
The utility model is intended to provide a kind of air pollutants detection device, is detected with solving the prior art using gravimetric method
When Atmospheric particulates, because Atmospheric particulates are attached in inner wall of the pipe, lead to asking for the measurement result inaccuracy of Atmospheric particulates
Topic.
One of this programme air pollutants detection device, including pedestal, pipeline, exhaust fan, assay balance and at least
Mounting cylinder open at one end, mounting cylinder is horizontally disposed and is fixedly connected on the base, and the pipeline is equipped with sliding block, sliding block
Across the mounting cylinder lower wall and be slidably connected with it, there are gap between the pipeline and mounting cylinder, the pipeline
The equal closed loop in both ends is equipped with plastic foil, and for the plastic foil airtight connection of pipeline one end in the open end of the mounting cylinder, pipeline is another
The air inlet of the closed connection exhaust fan of the plastic foil at end；It is used to stop the mistake of Atmospheric particulates in the pipeline equipped with multilayer
Filtering layer；The assay balance level and exhaust fan are fixedly connected on the base, the scale pan of assay balance and the sliding block
Lower end face contact.
The working principle of this programme and its utility model has the advantages that in use, by assay balance, can weigh sliding block, pipeline, modeling
Expect the initial weight of film and filter layer.After the completion of weighing, start exhaust fan, exhaust fan is run after a certain period of time, according to exhaust fan
Power calculates the air capacity extracted into atmosphere；With the extraction of air, the Atmospheric particulates in inflation are through plastic foil, pipe
Road and multiple layers of filters, are then discharged through exhaust fan, adhere to or hinder on plastic foil, in pipeline and on filter layer in the process
The Atmospheric particulates of gear can show that total weight, total weight subtract initial weight and can be obtained in extraction air by assay balance
Atmospheric particulates weight, and then although it is understood that the content of Atmospheric particulates in air, and then establish for the detection of air pollutants
Fixed basis.In the process, since Atmospheric particulates are either adhered to plastic foil, in pipeline or on filter layer, with emphatically
The increase of amount, pipeline can weigh out by sliding block slide downward in the lower wall of mounting cylinder on assay balance, into
And the detection accuracy of Atmospheric particulates is significantly improved, the detection accuracy for improving air pollutants has good effect.
Further, the sliding block there are two and be respectively fixedly connected with upper and lower surfaces in pipeline, positioned at pipeline upper surface
Sliding block vertical sliding is connected in the upper wall body of the mounting cylinder.By the way that two sliding blocks are arranged, the mistake of air is extracted in exhaust fan
Cheng Zhong, two sliding blocks are slidably connected in the upper and lower wall body of mounting cylinder, can be played position-limiting action to pipeline, be enhanced the stabilization of pipeline
Property, the probability that pipeline is shaken is advantageously reduced, and then help to improve the detection accuracy of Atmospheric particulates.
Further, the filter layer is filter paper or gauze.The gap of filter paper or gauze is smaller, has to Atmospheric particulates
There is stronger barrier effect.
Further, the filter layer includes filter paper and gauze.Filter layer includes simultaneously gauze and filter paper, for enhancing
The filtration of filtering layer and intensity all have preferable effect, and the two is made to reach balance preferably.
Further, the wall body of the mounting cylinder is equipped with handle.By the way that handle is arranged, easily facilitates and air pollutants are set
It is standby to be taken, taken, it carries more convenient.
