Ball surrounds the packing
 |
Metal Ball surround packing whether adoption metal sheet metal that
Company develop, BASF of German, wash and make, Opening in a wall that
has opened platoon two while having and stretched the something shaped
like a tongue leaf on the ring wall. Each row of opening in a wall has
five tongues leaves, each tongue leaf is curved to the ring , point to
the ring heart, Office nearly looks tower in centre, have two upper and
more lower position of opening in a wall stagger each other, Make an appointment
for about 35% of the area of wall of the whole ring in the whole area
that generally makes
the hole, compared with the situation with drawing the west ring packing,
Because Ball has surrounded the packing and has a lot of openings in a
wall have been held on the ring wall, makes the gas and liquid in the
tower can be passed from the window freely, So packing air liquid than
draw distribution situation west ring packing have greater improvement
of layer, It separate performance have and improve obviously, so industry
use extensive, people surround to Ball research of packing even relatively
sufficient, So Ball surrounds the packing it is still the fifth of main
annular packing adopted at present, Equipment limited company of the petrochemical
industry, according to the sector standard HG/T211556-95 production in
the People's Republic of China in sea salt new century, The following
watch of parameter shows its characteristic:
Form 1: Steel Ball surrounds the characteristic parameter of packing with carbon:
