G505 Filter Medium Tester Principle - China

price: 1.00 Dollar US$

G505-filter Medium Tester principle 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, forming a uniform concentration, and then evenly distributed throughout the vertical pipeline and flowing 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.

The dust forms a powder cake, which causes the pressure drop to increase.

The differential pressure sensor detects the change of the 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.

After that, the tested filter material filters the dust again, and so on.

The cleaning pulse must be time-accurate and highly repeatable, so that the pressure surface of each pass through the filter material is even and consistent.

The removed powder and remaining dust fall down with the vertical airflow to the dust collector at the bottom of the dirty air pipe.

The instrument is also equipped with a dirty gas filter, so that dust will not redisperse in the upstream of the dirty gas of the tested filter material, resulting in ambiguous dust concentration, making the measurement invalid (especially the important parameter: residual pressure drop value); this design is realized Long-term error-free operation does not require frequent and complete interruption of measurement due to cleaning up dust deposits.
