Static filtration performance tester for filter media and bags

Static filtration performance tester for filter media and bags

The new G505 filter material filtration performance tester can simulate the use process of filter bags in bag filters. The filter material is aged according to the standard process (usually lasting for several days), and when the filter material performance stabilizes, the "characteristic filtration indicators" (including pressure drop curve, residual pressure drop, filtration/cleaning cycle, residual dust layer quality, and dust quality passing through the filter material sample) of specific concentrations of aerosols before and after passing through the filter material can be tested. The results can be used to evaluate the filtration efficiency of the filter material in actual use.

Suitable for professional filter material testing:

The filter material filtration performance tester is a testing instrument designed to evaluate the dynamic and static dust removal efficiency, filtration performance, etc. of the filter material and filter bag used in bag type dust collectors. By simulating the real situation of the filter material in actual use, the performance evaluation parameters of the filter material can be quickly obtained, and the quality, performance, service life, etc. of the filter material can be accurately evaluated.

Providing data basis for the research and development of new filtering materials, product quality control, material performance verification, etc., is the best choice for product performance verification in scientific research, testing, industrial production and other fields.

Meets multiple testing standards:

ISO 11057 Air Quality - Test Method for Filtration Performance of Cleanable Filter Media

ASTM D6830 Test Method for Determining Pressure Drop and Filtration Performance of Cleanable Filter Media

VDI/DIN3926 Standard Test Method for Evaluating Cleanable Filter Media

GB/T 6719 Technical Requirements for Bag Dust Collectors

JIS Z8909-1 Test Method for Filter Media for Dust Collection - Part 1: Filtering Efficiency, etc

Principle of filter material filtration performance tester:

The air is first sent into the vertical dust generating pipeline to generate a dirty airflow filled with dust. Dust is dispersed with compressed air in the dust generator, forming a uniform concentration and evenly distributed throughout the vertical pipeline, flowing downwards. Some reach the horizontal pipeline and pass through the tested filter material with the suction airflow, exposing it to a constant airflow and dust concentration to simulate the operation of the cleanable filter material.

The dust forms powder, which leads to the increase of pressure drop. The differential pressure sensor detects the change of pressure drop before and after the test filter material in real time. Once the pressure drop reaches the preset value, the system releases the clean compressed air pulse towards the powder generated by the dirty air side, which will not affect the air flow for back blowing soot cleaning (online cleaning). Afterwards, the tested filter material re filtered the dust, repeating this cycle. The cleaning pulse must have precise timing and high repeatability, so that the pressure surface passing through the filter material is average and consistent each time.

The removed powder and the remaining dust fall down with the vertical airflow to the dust collector at the bottom of the dirty gas pipe. The instrument is equipped with a dirty gas filter to prevent dust from dispersing upstream of the dirty gas in the tested filter material, resulting in unclear dust concentration and rendering the measurement ineffective (especially important parameter: residual pressure drop value); This design achieves error free long-term operation without the need for frequent and comprehensive interruptions in measurement due to dust deposition cleaning.
