Abstract
The invention discloses an air filtration material filtering efficiency testing device, wherein the testing device includes a gas inlet chamber and a gas testing chamber; the gas inlet chamber is provided with a gas inlet, the gas testing chamber is provided with a gas outlet and a test port, an air filtration material and a draught fan are arranged between the gas inlet chamber and the gas testing chamber. The area of the gas inlet is greater than the area of the gas outlet. The gas inlet chamber is in a negative pressure state, and the gas testing chamber is in a positive pressure state. The air filtration material is located at an inlet or an outlet of the draught fan. The gas testing chamber is provided with a curved surface, and the test port is formed in the middle of the curved surface. The air filtration material is a single-layer, composite or pleated composite-structural material. The testing device has the beneficial effects that the structure design is concise, and a test result can be intuitively and quickly observed; no airflow blind corner exists, the uniformity of the quality of tested air can be ensured; and the gas testing chamber is still in the positive pressure state, the requirement on chamber leakproofness can be reduced, the gas turbulence is reduced, and mass production is easy to achieve.
Description
Technical field
The present invention relates to a kind of filtration efficiency proving installation of air filting material.
Background technology
At present, China become global atmosphere pollute area, particularly Jing-jin-ji region, the Yangtze River Delta, Chengdu-Chongqing, central plain area etc. the most serious be global pollution, the average annual concentration of PM2.5 is more than 70 micrograms/m
3, exceed more than 2 times of national standard, higher than more than 7 times of WHO standard.In addition on the one hand, indoor pollution has become the important threat to the life of people's house and health, and Environment Protect in China association relevant data statistics shows: once carried out luxurious finishing in 90% leukemia children man, annual 2100000 children die from luxurious finishing; The house decoration formaldehyde of 80%; 70% pregnant woman's miscarriage is relevant with environmental pollution.Indoor environmental pollution has become one of killer having a strong impact on modern humans's health.
In the face of increasingly serious air pollution present situation, industry is also weeded out the old and bring forth the new, and various air strainer, air purifier, central ventilation system emerge in an endless stream, and existing multiple air filtration product introduction market, enters in ordinary consumer man.But for a long time, as Testing index most crucial in air filtration product---filtration efficiency, need to use the measuring table of complicated specialty, particle counting instrument, meter heavy weighing apparatus, gas analyzer etc., and the operating cycle is long, data processing amount is very large, efficiency is low, and air filter efficiency cannot intuitively present rapidly.
Summary of the invention
The present invention is according to above deficiency, provide a kind of filtration efficiency proving installation of air filting material, this proving installation test speed is very fast, can allow consumer only can direct vision testing efficiency with naked eyes, experience air filtration effect, also may be used for factory quality monitoring, improve the quality management level of air filtration product.
Technical scheme of the present invention is:
A filtration efficiency proving installation for air filting material, is characterized in that, comprising: inlet chamber and survey air cavity, and inlet chamber is provided with air intake opening, surveys air cavity and is provided with gas outlet and test port, installs air filting material and blower fan between inlet chamber and survey air cavity.
The area of described air intake opening is greater than the area of gas port.Reduce air resistance, increase and survey air cavity air pressure.
Described inlet chamber is negative pressure state, and surveying air cavity is barotropic state.Surveying air cavity is that barotropic state contributes to improving accuracy of detection, and when preventing from surveying air cavity gas leakage, ambient atmos affects accuracy of detection.
Described air filting material is positioned at the import or export of described blower fan.
Described survey air cavity is provided with curved surface, and described test port is positioned at the middle part of this curved surface.Dead angle is there is in curved surface Streamline Design when can prevent air from flowing.
Described air filting material is the material of individual layer, compound or the composite structure such as pleating.
End face and the bottom surface of described inlet chamber and survey air cavity are plane, and side comprises plane and flexure plane, and flexure plane includes the curved surface of described survey air cavity.
Described air intake opening and the gas outlet farthest between inlet chamber and survey air cavity.
Beneficial effect of the present invention:
Compared with existing air filter efficiency detection technique, decoration structure features simple design, can observation test result intuitively; Existing air filter efficiency sense cycle is in sky, and the present invention can detect the filtration efficiency of air filting material fast, and a few minutes can go out result; Owing to adopting fairshaped cavity, air can fill whole test chamber very soon, and there is not dead space, can ensure the homogeneity of tested air quality; Due to the particular design of cavity, during test, test chamber is in malleation all the time, and can reduce the requirement for cavity airtight, device easily makes on a large scale; Test chamber keeps malleation, and exhaust ports farthest decreases gas turbulence.
