Filter material filtration performance tester Static dust removal efficiency Shanghai Chengwei

Filter material filtration performance tester filter material filtration performance tester can simulate the use of filter bags in the bag filter, according to the standard process of aging the filter material (usually needs to last for many days), the performance of the filter material tends to be stable, test a specific concentration of aerosol through the filter material before and after the "characteristic filtration index" (including pressure drop curve, residual pressure drop, filtration/cleaning cycle, residual dust layer quality and dust quality of the filter material sample, etc.
) The results can be used to evaluate the filtration efficiency
of the filter material in the actual use process 。 Detailed introduction for professional filter material testing: filter material filtration performance tester is a test instrument designed for evaluating the dynamic and static dust removal efficiency and filtration performance of filter materials and filter bags for bag filters, by simulating the real situation of filter materials in the actual use process, quickly obtain the performance evaluation parameters of filter materials, and accurately evaluate the quality, performance, life, etc.

of filter materials.
It provides data basis for the research and development of new filter materials, product quality control, material performance verification, etc.
, and is the choice for
product performance verification in the fields of scientific research, testing, industrial production, etc 。 Complies with a variety of test standards: ISO 11057 Air quality – Test method for the filtration performance of cleanable filter media ASTM D6830 Test method VDI/DIN3926 Standard test method for evaluating cleanable filter media GB/T 6719 Technical requirements for bag filter collectors JIS Z8909-1 Test method for filter media for dust collection.
Part 1: Filtration efficiency Filter material filtration performance tester principle: air is first sent into the vertical dusting pipe to produce a dirty air flow
full of dust.
The dust is dispersed with the compressed air in the dust generator, and after forming a * concentration, it is evenly distributed throughout the vertical pipeline and flows downward, and part of the horizontal pipeline passes through the tested filter material with the suction air flow, so that it is exposed to a constant air flow and dust concentration to simulate the operation
of the cleanable filter material.
The dust forms a powder, resulting in an increase in pressure drop, and 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 a preset value, the system releases a pulse of clean compressed air towards the powder generated on the dirty side, backflushing (cleaning-in-place)
without affecting the airflow.
The tested filter material then filters the dust again, and so on
.
The cleaning pulse must be time-accurate and repeatable, so that the pressure surface of each filter material is evenly and evenly*
.
The removed powder and remaining dust fall down to the dust collector at the bottom of the dirty trachea
with a vertical air stream.
The instrument is also equipped with a dirty gas filter, so that the dust will not be redispersed upstream of the dirty gas of the filter material under test, resulting in unclear dust concentration, making the measurement invalid (especially important parameters: residual pressure drop value); This design enables error-free* operation without the need for frequent and complete interruptions to the measurement
due to cleaning up dust deposits.
Main test parameters: outlet dust concentration test filter material quality change initial residual pressure drop, average residual pressure drop, residual pressure drop increment average filtration cycle dust removal efficiency, penetration rate cleaning time, ash cleaning cycle static dust removal efficiency dynamic dust removal efficiency multi-point characteristics: filter material filtration performance tester is easy to use, efficient testing, can make the daily testing work in the laboratory simple, and versatile, flexible use, safe and stable
