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: |
