Description
Technical field
The present invention relates to a kind of filter membrane protection box that can deposit filter membrane and with the matching used weighing apparatus of filter membrane protection box and the weighing-appliance of getting the film device, being consisted of by filter membrane protection box and weighing apparatus and the using method of this weighing-appliance.
Background technology
Particulates thing of the prior art pollutes is not only the main cause that causes haze weather, and particularly pellet (PM2.5: be less than or equal to 2.5 micron particles things) can impact the health of human body, mainly respiratory system and cardiovascular system is damaged.Therefore particulate in air concentration is one of major criterion of judging air quality.
At present, the assay method of particulate in air concentration and motor vehicle exhaust emission particle concentration can be divided into manual monitoring method and automatic monitoring method.The manual monitoring method is called again gravimetric method, and what monitoring method was most widely used at present automatically is β attenuation sensors and trace vibration weighing apparatus method and light scattering method.Although β attenuation sensors and trace vibration weighing apparatus method are putative standard methods, can automatically monitor, and be simple to operate, is convenient to realize that monitoring method can't replace the manual monitoring method fully automatically.For manual detection method, its principle can reflect the concentration of particle comparatively accurately the most directly with directly perceived, also is the Main Basis of judging automatic monitoring method accuracy.But the running program of gravimetric method is more loaded down with trivial details, needs personnel operation in the process, and wherein of paramount importance link is taking, putting and weighing of filter membrane.The precision of weighing in the gravimetric method is the size of sampling amount in 0.1mg and 0.01mg(difference); therefore in the whole observation process to filter membrane to deposit and protect be the key of guaranteeing data accuracy; method comparatively commonly used is to deposit filter membrane with double dish or valve bag now; but filter membrane also needs long balance before weighing; so in balance and weighing process, need the filter membrane that takes, puts repeatedly; personnel need repeatedly to contact with filter membrane; can in this process, impact filter membrane unavoidably, particularly on being loaded with the impact of Particulate filter after the sampling.Manual monitoring method misalignment is often because depositing and protect improper and cause filter membrane.
