The standard test stand for evaluating the dynamic dust-removal behavior of filtering material and the test method have been presented

the simplified process of said test being put forward.In the initial stage of test

only six times of the filtered dust cleaning have to be carried out;the aging treatment stage is 10 000 times of pulsed back-blowing(no dust appear);the stabilation treatment stage being omitted;in the formal test stage

only ten times of filtered dust cleaning treatment have to be conducted.By using the simplified test method

the dynamic behavior test for a PTFE precoated filtering material used in the industry has been carried out

the results of test show that the increament of filtering resistance is smaller

the filtering period is shortened by a big margin

the concentration of total particles at the outlet is very low;it means that the resistance of filtering material after aging treatment is more easily to reach 1 000 Pa

dust cleaning has to be more frequent.The dynamic dust-removal behavior test of filtering material after simplification can more accurately reflect the behavior of filtering material.
