The symmetrical diameter of mounting rail mounting hole divides this hexagonal angle equally；The distance between two neighboring spray thrower mounting rail group, top layer
Distance and basecoat spray thrower mounting rail group of the spray thrower mounting rail group apart from lower body lower section (32) upper surface are apart from lower
Body lower section (32) lower end surface is equidistant；
[4] upper and lower side of corresponding ring flange and lower body lower section (32) is connected；The lower end of lower body lower section (32)
Ring flange and absorption column foot tower are fixed together；Put down the connection of upper body lower section (31) and ontology upper section (2) being connected together
Zoarium, and the upper end of the association and lower body lower section (32) is fixed together by flange arrangement；
[5] minimum one group of the spray thrower mounting rail that a long spray thrower mounting rail passes through lower body lower section (32) is pacified respectively
Hole is filled, and is supported on the both ends of the spray thrower mounting rail in the spray thrower mounting rail mounting hole of left and right；First the spray thrower is installed
Beam carries out the first positioning adjustment, then carries out second of positioning adjustment；Then the spray thrower mounting rail fix tightly；[6] in the spray
The both ends of leaching device mounting rail are nested with spray thrower mounting rail connection support plate (10) respectively；First spray thrower mounting rail is connected and is supported
The weldering of the outer surface of plate (10) and lower body lower section (32) connects together, then spray thrower mounting rail connection support plate (10) and sprays
The weldering of device mounting rail connects together；Respectively existed with the both ends solid welding of one piece of spray thrower mounting rail beam hole sealing plate (8) and spray thrower mounting rail
The spray thrower mounting rail beam hole is sealed together；
[7] according to [5] and [6] the good another root long of step solid welding spray thrower mounting rail；
[8] continue the good two short spray thrower mounting rails of step solid welding according to [5] and [6]；
[9] upper two floor stringers (6) are welded between two long and short two root spray thrower mounting rail combinations；
[10] middle layer is installed according to the step of [5] to [9], then installs top layer further in accordance with the step of [5] to [9]；
So far, the manufacture of absorption tower ontology is completed.
