01.
Corrugated packing Currently most of corrugated packing
industrial application of the structured packing, it is by
many corrugated sheet composed of a disc-shaped filler, the
corrugation and the inclination of the tower axis 30 กใ and
45 กใ of two, two adjacent corrugated the board reverse rely
stack assembly. Each disk filler vertically mounted within
the column, between two adjacent filler staggered
arrangement of 90 กใ.
02. Corrugated packing net corrugated packing and Corrugated
Packing can be divided into two categories according to the
structure, the material has metal, plastic and ceramic
divided.
03. Metal gauze packing is the main form of network
corrugated packing, it is made of wire mesh. Metal gauze
packing pressure drop, high separation efficiency,
especially for the precise distillation and vacuum
distillation unit, embarrassed isolate Department,
Department of distillation of heat-sensitive material
provides an effective means. Despite its high cost, but
because of its excellent performance has been widely used.
04. Metal plate corrugated packing is a major form of plate
corrugated packing. Many f5mm orifice of the filler on the
corrugated board sheet stamping, can play the rough
distribution of the liquid on the plate, strengthening the
role of transverse mixing. Rolled into the fine grooves on
the corrugated board sheet, can play a liquid film on the
fine distribution plate, and to enhance the role of the
surface wet ability. Metal corrugated plate packing high
strength, corrosion resistance, especially suitable for
large diameter column and gas-liquid load occasions.
05. Metal rolling corrugated plate packing is another
typical plate corrugated packing. It is with metal plate
corrugated packing the main difference is that the plate
surface is not punched holes, but the penetrating hole,
jarring way a very dense pore size of 0.4 ~ 0.5mm small
puncture hole on the plate rollers. Separation corrugated
packing capacity similar network, but the anti-blocking
ability than net corrugated packing, and the price is cheap,
is widely used.
06. Corrugated packing the advantages of compact structure,
small resistance, high mass transfer efficiency, large
capacity, large specific surface area (commonly used
125,150,250,350,500,700 several). The corrugated packing
shortcomings is not suitable for processing viscosity, easy
polymerization or suspended solids material handling,
clean-up difficulties and high cost.
07. Pulsed packed pulsed packed with necking hollow
prismatic individuals, held together by a certain way of a
structured packing. Pulsed packed assembly, will form the
porous prismatic channel necking with its longitudinal
runner alternating contraction and expansion of the
gas-liquid two-phase through strong turbulence. In the the
necking segment, the highest gas velocity, turbulence
intense, thus enhancing mass transfer. Expanding segment,
the gas velocity is minimized, to achieve the separation of
the two phases. Flow channel contraction, expand alternately
repeated to achieve a "pulse" the mass transfer process.
08. Pulse filler is characterized by large handling
capacity, low pressure drop, vacuum distillation filler.
Liquid distribution because of its excellent performance
make the reduced amplification effect, it is particularly
suitable for the large column diameter occasions.
