Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated.
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Oil mist separator of the present invention, adopts three stage structure.The first order adopts High Rotation Speed centrifugal process to carry out initial gross separation to bulky grain mist of oil; The second level adopts motion to clash into partition method and is separated small particles mist of oil, assembles; The efficient Coalescence filter core of the third level adopts multilayer, many materials composite application, and variable orifice gap multiple conversions structure, carries out high-efficiency accumulation separation to ganglion.
Second level collision is separated chemical fibre or glass fibre, the metal sintering felt such as stainless steel cloth, pompon or PP, PE, PVC, PET, polyester in filter core employing 10-150 order pore diameter range, the great depth of composition single or multiple lift thickness between 15-65mm, large aperture filtration.Small particles mist of oil by time constantly collide separate mesh, surface tension characteristics difference is utilized to make the mist of oil of small particles progressively be gathered into bulky grain in collision process, part bulky grain is back to fuel tank along cartridge surface along gravity direction with oil droplet form, remaining particle, because conducting oneself with dignity not, still continues to enter the third level with air-flow with mist of oil form.Collision is separated filter cartridge construction schematic diagram as shown in Figure 4.
The third level efficient coarse separation filter core core utilizes different filtration of material spaces different, the principle that oleophylic/oleophobic polarity is different, realizes filtration, coalescent, separation 3 kinds of objects, thus ensures final separating effect.
