Description
Technical field
The present invention relates to a kind of ripple board component filler, more particularly to polytetrafluoroethylene (PTFE) ripple board component and its preparation method.Category
In structured packing technical field.
Background technology
Filler refers to the material being filled in other objects.In Chemical Engineering, filler refers to loaded on lazy in packed column
Property solid material, it is the contact surface for increasing solution-air that it, which is acted on, makes its mutually strong mixing.There are dispersed filler and structured packing two
Kind.Dispersed filler such as Pall ring and Raschig ring.Structured packing is the filler neatly piled up by certain geometrical configuration arrangement.Rule
Whole filling kind is a lot, can be divided into grid packing, ripple packing, Impulse packing etc. according to its geometry.Ripple packing be by
There are 30 ° and 45 ° two kinds in the inclination angle of the discoid filler of many corrugated sheets composition, ripple and tower axle, adjacent two ripple during assembling
Plate is reversely by folded.Each disk filler is vertically loaded on the 90 ° of arrangements that interlock in tower, between two adjacent disk fillers.Ripple packing can by structure
It is divided into corrugated wire gauze packing and the major class of mellapak packing two, its material has point of metal, plastics and ceramics etc. again.Metallic plate ripple is filled out
Material is a kind of principal mode of mellapak packing.Many apertures are stamped with the corrugated cardboard sheet of the filler, distribution plate can be played
On liquid, strengthen empir-ical formulation effect.Tiny rill is rolled on corrugated cardboard sheet, can play liquid on fine distribution plate,
Strengthen the effect of surface wettability.Metallurgic orifice corrugated packing intensity is high, larger suitable for major diameter tower and gas-liquid load
Occasion.But because the resistance to corrosion of metal is weaker, the especially mass transfer of highly acid material, usually used two or three months will stop
Machine changes filler, and huge loss is brought to enterprise.
