Owing to adopted the technical solution of the utility model, the utlity model has following advantage:

1, because the net-filter assembly in the utility model structure has set gradually superfine fibre filter material layer and foams Guinier-Preston zone from inside to outside, superfine fibre filter material layer can be by blocking, inertial collision, diffusion and molecular separating force capture the drop formula particle of 3 μ m-0.01 μ m, solid particle is attached to motionless on the fiber, to move to the crosspoint coalescent and drop can down be swum along the long fibre of filter material, drop increases change greatly gradually after coalescent, the small pressure reduction that air-flow forms makes the fleece of drop by filter core, and last coalescent drop becomes the foam Guinier-Preston zone surface, the outside that drop formula liquid film appears at filter core.

2, owing to adopted highly porous oil resistant plastics foams Guinier-Preston zone in the technical solutions of the utility model, foams are collected and are caught minimum drop and droplet congregating is increased, and follow air-flow and move downstream, are deposited to the hydrops district under the effect of gravity.

3, owing to net-filter assembly in structure of the present utility model has set gradually superfine fibre filter material layer and foams Guinier-Preston zone, therefore the solid in the gas is separated with liquid impurity.

4, owing to be provided with the ventilative internal layer of sheet material conduct that contains through hole in the isolated by filtration filter core, strengthened the overall construction intensity of isolated by filtration filter core.

5, in order to solve filter course joining in the technology formerly, bonding problem, the ventilative internal layer in the utility model structure has adopted the sheet material that contains through hole, because the rigidity of sheet material is big, therefore can avoid the situation of internal layer joining.
