Description
Technical field
The present invention relates to structured packing technical field, in particular to a kind of polytetrafluoroethylene (PTFE) disc type structured packing and preparation side
Method.
Background technique
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, effect is the contact surface for increasing solution-air, 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 arranged by certain geometrical configuration, the filler neatly piled up.Rule
There are many whole filling kind, 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 axis, when assembling adjacent two ripple
Plate reversely leans on folded.Each disk filler is vertically loaded in tower, and interlock 90 ° of arrangements between two adjacent disk fillers.Ripple packing can by structure
It is divided into corrugated wire gauze packing and mellapak packing two major classes, material is divided into metal, plastics and ceramics etc. again.Metal plate ripple is filled out
Material is a kind of principal mode of mellapak packing.There are many apertures for punching press on the corrugated cardboard sheet of the filler, can play distribution plate
On liquid, reinforce empir-ical formulation effect.Tiny rill is rolled on corrugated cardboard sheet, can play liquid on fine distribution plate,
Enhance the effect of surface wettability.Metallurgic orifice corrugated packing intensity is high, is suitable for major diameter tower and gas-liquid load is biggish
Occasion.But since the resistance to corrosion of metal is weaker, especially the mass transfer of highly acid substance, usually used two or three months will stop
Machine replaces filler.
Fluoroplastics, especially polytetrafluoroethylene (PTFE) have very strong corrosion resistance, are made into structured packing and are expected to solve
Above-mentioned problem.In the application, plastics compare metal, and maximum disadvantage is that plastics lack the rigidity of metal, therefore uses
Full polytetrafluoroethylene (PTFE) is fabricated to structured packing needs and provides new thinking in terms of the rigidity of material and intensity.Authorization Notice No.
A kind of disc type structured packing of polytetrafluoroethylene (PTFE) is disclosed for the Chinese invention patent of CN104841353B, including by several edge-on
Polytetrafluoroethylene (PTFE) corrugated plating be formed by stacking body construction, formed in the body construction by polytetrafluoroethylene (PTFE) cranse banding
Binding structure is placed through the reinforcement structure formed in the body construction by polytetrafluoroethylene (PTFE) reinforcing rib level and by polytetrafluoro
The body construction and binding structure are sewed integral suture texture by ethylene line；Polytetrafluoroethylene (PTFE) reinforcing rib is by rigid core
Stick is set in inside polyfluortetraethylene pipe, and has both rigidity, corrosion resistance for what polyfluortetraethylene pipe both ends melting welding was formed
The sealing structure of energy；The width direction of the ripple of the corrugated plating and the width direction of corrugated plating form angle α, thus adjacent
Two pieces of corrugated platings wave crest and wave crest point contact formation mass transfer section in edge-on overlapping, 30 °≤α≤60 °；Positive and negative two table of corrugated plating
Face is equipped with coarse structure, and plate body has several equally distributed through-holes.The corrugated plating of the filler, is rolled using polytetrafluoroethylene (PTFE)
Prepared by band base band, calendering is flat, smooth and non-porous with base band, and corrugated plating is undulatory, coarse and has
Uniformly densely covered hole.Therefore it needs to handle calendering tape base band by a variety of mechanical equipments, to form corrugated plating.It is common to set
It has: roll squeezer, to form rough surface；Perforating press, to form uniformly densely covered hole；There are also corrugating machines, will be put down by hot pressing knife
It is straight, hole punch, roll-in goes out the calendering band base band hot pressing of rough surface and goes out ripple struction.Problem is: passing through hot pressing knife
Processing, the coarse structure originally produced by roll squeezer pressed to a certain extent, affects the distribution and stop of liquid, shadow
The wetability of filler is rung, to impact to liquid mass transfer.
