Product Description:

VDI filter material filtration performance tester

The VDI filter material filtration performance tester



is used to evaluate the dynamic and static dust removal efficiency and filtration performance of the filter material. By simulating the real situation of the filter material in actual use, it can quickly obtain the performance evaluation parameters of the filter material and accurately evaluate the quality of the filter material, Performance and life expectancy.

Test details:

It can simulate the use process of the filter bag in the bag filter, and the filter material is aged according to the standard process (usually for several days). When the performance of the filter material stabilizes, test the characteristic filtration index of the specific concentration of aerosol before and after passing the filter material "(Including pressure drop curve, residual pressure drop, filtration/cleaning cycle, remaining dust layer quality and dust quality of the filter material sample, etc.) The results can be used to evaluate the filtering efficiency of the filter material in actual use.

Test principle:

1. The air is first sent into the vertical dust generating duct to generate a dirty air flow full of dust. The dust is dispersed with the compressed air in the dust generator, and the concentration is formed evenly distributed throughout the vertical pipeline and flows downwards. Part of the horizontal pipeline passes through the tested filter material with the inhalation airflow, so that it is exposed to a constant airflow and dust concentration. To simulate the operation of cleanable filter media.

2. The dust forms a powder cake, which leads to an increase in pressure drop. The differential pressure sensor detects the change in pressure drop before and after the tested filter material in real time. Once the pressure drop reaches the preset value, the system releases a pulse of clean compressed air toward the powder formed on the dirty side, and performs back-blowing and cleaning (on-line cleaning) without affecting the air flow.

3. The tested filter material filters the dust again, and so on. The cleaning pulse must be accurate in time and high in repeatability, so that the pressure surface of the filter material is evenly balanced each time.

4. The removed powder and remaining dust fall down with the vertical airflow to the dust collector at the bottom of the dirty air pipe. Equipped with a dirty gas filter, so that the dust will not redisperse in the upstream of the dirty gas of the tested filter material, resulting in an ambiguous dust concentration, which makes the measurement invalid (especially the important parameter: residual pressure drop value); this design achieves error-free The long-term operation of the instrument does not require frequent and comprehensive interruption of measurement due to cleaning up dust deposits.

Applicable standards:

VDI/DIN3926 Standard Test Method for Evaluating Cleanable Filter Media

ISO11057 Air Quality-Test Method for Filtering Performance of Cleanable Filter Media

ASTM/D6830 test method to determine the pressure drop and filtration performance of cleanable filter media
