Every layer of ripple mesh sheet 11 includes multiple crest portions and multiple trough portions, the wave between every two layers adjacent of ripple mesh sheet
Peak potion and trough portion are oppositely arranged, and are fixedly connected by welding between every two layers adjacent of ripple mesh sheet, so that
Multiple curved filtration channels 12 are enclosed between per two layers adjacent of ripple mesh sheet.
The shape of the curved shape groove of the ripple mesh sheet is that cosine is linear, and the wire mesh is stainless steel cloth, is made
Its thickness is much higher than stainless steel cloth gas-liquid separation deoiling net, and in the identical situation of specification of net, the closed assembly quantity of mesh sheet is big
Big to reduce, material utilization amount greatly reduces.
It is equipped with location hole in every layer of ripple mesh sheet, strings ripple mesh sheet to just in advantageous welding process.
Before the mesh of stainless steel cloth is not filled by oil droplet, oil laden air is divided into two parts the present embodiment: one
The mesh that lease making crosses stainless steel cloth reaches the another side of net.Since its molecular diameter of ingredient of composition air is much smaller than oil droplet
Diameter, so air can be very good through net, and oil droplet can be then blocked；Another part is formed between ripple mesh sheet
Channel reach net another side.It is rough due to ripple mesh sheet, so that this partial air (net smooth compared with surface
Piece) it is more likely formed sinuous flow, so that the oil droplet in oil laden air, which collides, is combined into the probability increase of big oil droplet, and big oil droplet quilt
The probability that ripple mesh sheet intercepts is much higher than thin oil droplet.B, after the mesh of oil droplet filling stainless steel cloth, on ripple mesh sheet surface
It will form oil film.Due to " similar compatibility " principle of substance, the formation of oil film makes ripple mesh sheet to the oil droplet adsorption energy in air
Power enhancing.
