Abstract
The invention discloses a fluoroplastic Pall ring for a packing tower. The fluoroplastic Pall ring comprises a Poll ring body, wherein the Pall ring body is respectively provided with a stainless-steel bottom ring, a middle annular ring and an upper annular ring, and is of a structure with an upper layer and a lower layer; simultaneously, a solid middle cylinder body is arranged at the middle of the Pall ring body; and the middle part of the whole Pall ring body is penetrated into a whole body by the middle cylinder body. The fluoroplastic Pall ring disclosed by the invention has the advantages of large flux, less resistance, high separating efficiency and large operation elasticity and the like, is high in transferring efficiency and is applicable to the packing towers in various industries.
Description
Technical field
The present invention relates to fluorine plastic product field, particularly relate to a kind of packed tower fluoroplastics Pall ring.
Background technology
In packed tower field, extensive filler has stainless steel metal filler, ceramic packing, PVC plastic filler, but above-mentioned filler is in packed tower chemical reaction, there is various shortcoming, and packed tower environment is severe, and the service life of above-mentioned material is low.
Polytetrafluoroethylene (PTFE) is modal a kind of fluoroplastics, and have excellent chemical property and chemical stability, apply in packed tower, quality is good, and the life-span is long.Polytetrafluoroethylene (PTFE) can the chemical attack of resistance to organic matter and inorganic matter, and does not play adhesive attraction to material.
The invention provides a kind of fluoroplastics Pall ring for this reason, adopt fluoroplastics to make, packed tower gas liquid state is exchanged fully, and efficiency is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of packed tower fluoroplastics Pall ring, and Pall ring can adapt to complicated rugged environment in packed tower, and gas liquid in packed tower can fully be mixed, and increases the area that contacts with each other of material.
Described fluoroplastics Pall ring adopts polytetrafluoroethylene (PTFE) and polyparaphenylene phenol, both employings mixing composition.
Wherein, polytetrafluoroethylene (PTFE) is commonly called as PFA resin, the fluoroplastics of newer melt-processable, the fusing point of PFA is high, density is 2.13 grams/cc to 2.16 grams/cc, PFA is heat-resisting, cold-resistant, chemical stability, mechanicalness, insulating properties, self lubricity, folding resistance, resistance to cracking is excellent, simultaneously, PPL is added in this Pall ring filler, PPL is polyparaphenylene phenol, metallurgical, ideal wear-resisting in the industries such as chemical industry, encapsulant, high life, high temperature resistant, simultaneously, polyparaphenylene Heat stability is good, corrosion resistance, self-lubricating property is better than molybdenum bisuphide and graphite, the strand of PPL, due to very large rigidity and regularity, make it cannot not be molten insoluble, self machine-shaping difficulty, the blended use of other materials need be filled, Pall ring of the present invention uses polytetrafluoroethylene (PTFE) and position polyphenyl phenol compound to make.
Described a kind of packed tower fluoroplastics Pall ring, comprise: Pall ring body, Pall ring body is cylindrical structure form, described Pall ring body is provided with stainless steel foundation ring respectively, middle loop section, upper loop section, Pall ring body is upper and lower double-layer structure, be understructure between stainless steel foundation ring and middle loop section, be Pall ring superstructure between middle loop section and upper loop section.
Simultaneously, solid intermediate cylindrical entity is provided with in described Pall ring body middle, intermediate cylindrical entity runs through whole Pall ring body mid portion and is integrated, be provided with cylinder at described intermediate cylindrical entity edge and strengthen arc-like sheet, meanwhile, strengthen arc-like sheet at described cylinder and be provided with lower arcuate tongue piece group with being connected between Pall ring inner body wall.
A kind of optimal technical scheme, the described tongue piece quantity often organizing arc tongue piece group is 4, adopts the symmetrical half-moon-shaped structure of arc.
Be substantial annular hole between described arc tongue piece, shared by substantial annular hole, Pall ring area of section is more than 90%, is conducive to liquid, the abundant exchange of gas etc.
Connect between described lower arcuate tongue piece group and be provided with support post, support post is bindiny mechanism and the supporting mechanism of Pall ring double-layer structure, and support post connects Pall ring as a whole.Described support post is 4 support posts.
Described Pall ring outer wall is provided with the oval fenestra of two rows, a kind of optimal technical scheme, described fenestra ovalis hole number is often arrange 5-8, perforate on ring wall, make gas on ring wall, fluid exchange abundant, the internal surface area of Pall ring can be fully utilized, and voidage reaches 90% simultaneously, therefore not easily block, pressure drop is little.
The invention has the beneficial effects as follows: a kind of packed tower of the present invention fluoroplastics Pall ring filler has that flux is large, resistance is little, separative efficiency is high and the advantage such as operating flexibility is large, and transmission efficiency is high, and the packed tower being applicable to various industry uses.
