Description
Technical field
The utility model relates to the technology of a kind of environmental science, specifically a kind of haze mask performance test system.
Background technology
Affected by many factors, haze weather all over China gets more and more, increasingly severe.Under haze weather, air pressure reduction,
Inhalable Particulate abruptly increase, air flow property are poor, and noxious bacteria and virus, to slowing of around spreading, cause air
Middle virus concentration increases, and the risk of pathophoresis improves, and easily causes human respiratory disease.And wear mask and can play
The protective action of effect, but the non-standard haze masks such as misuse industrial anti-dust mask easily cause health problem.The most various types of
The mask of type uses environment different with testing standard, thus model is different, allows people be difficult to differentiate between and chooses.
Utility model content
This utility model is for deficiencies of the prior art, it is proposed that a kind of haze mask performance test system, overcomes
The defect that testing standard is different, selects haze mask to provide reference for user.
This utility model is achieved through the following technical solutions,
This utility model includes: aerosol generator, air compressor, buffer, upstream adapter, downstream adapter, effusion meter,
Detection adapter and PM2.5/PM10 detector, wherein: aerosol generator, air compressor, buffer and upstream are taken over successively
Being connected, downstream adapter is correspondingly arranged with upstream adapter, and downstream adapter, effusion meter, detection adapter and PM2.5/PM10 detector depend on
Secondary connected.
It is provided with valve between described buffer and upstream adapter.
Described buffer is provided with pressure transducer.
Technique effect
Compared with prior art, this utility model has unified the test condition of haze mask, and experimental provision is easy to use；Avoid
The misuse of the non-haze masks such as industrial anti-dust mask, selects haze mask to provide reference for correct.

Described effusion meter 6 is threaded connection mode and is connected with downstream adapter 5, detection adapter 7.
Mask 11 operationally, is arranged between upstream adapter 4 and downstream adapter 5, such as Fig. 2 by the present embodiment by flange
Shown in；Start aerosol generator 1, open air compressor 2 afterwards and fill dusty gas, when in buffer 3 to buffer 3
Air pressure when reaching 1MPa, close air compressor 2, open valve 10 and regulate aperture, monitoring dust-laden with effusion meter 6
Gas flow, flows through PM2.5 and the PM10 value of dusty gas after mask 11 with PM2.5/PM10 detector 8 record, every
Certain time records once；By the aperture of control valve 10 in test process, control upstream adapter 4 and the pressure of downstream adapter 5
Difference, when the numerical value of pressure transducer 9 display is close to 0.15MPa, completes once to test；Change mask 11, keep remaining to survey
Test ring border is constant, repeats above-mentioned test process, records different mask 11 effect of haze under same test conditions.
