The symmetrical diameter of mounting rail mounting hole divides this hexagonal angle equally；The distance between two neighboring spray thrower mounting rail group, the superiors
Spray thrower mounting rail group is apart from lower body hypomere（32）The distance and basecoat spray thrower mounting rail group of upper surface are apart from lower
Body hypomere（32）The distance of lower surface is equal；
【4】Corresponding ring flange and lower body hypomere（32）Upper and lower side be connected；Lower body hypomere（32）Lower end
Ring flange and absorption column foot tower are fixed together；Put down body hypomere（31）With body epimere（2）The connection being connected together
Zoarium, and the association and lower body hypomere（32）Upper end be fixed together by flange arrangement；
【5】A long spray thrower mounting rail is passed through lower body hypomere respectively（32）Minimum one group of spray thrower mounting rail peace
Hole is filled, and the both ends of the spray thrower mounting rail is supported 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 supporting plate respectively（10）；First spray thrower mounting rail is connected and supported
Plate（10）With lower body hypomere（32）Outer surface weldering connect together, then spray thrower mounting rail connect supporting plate（10）And spray
The weldering of device mounting rail connects together；Respectively with one block of spray thrower mounting rail beam hole shrouding（8）Both ends solid welding with spray thrower mounting rail exists
The spray thrower mounting rail beam hole is sealed together；
【7】According to【5】With【6】The good another root long of step solid welding spray thrower mounting rail；
【8】Continue according to【5】With【6】The good two short spray thrower mounting rails of step solid welding；
【9】Two floor stringers in welding between two long and short two root spray thrower mounting rails combine（6）；
【10】According to【5】Extremely【9】The step of install intermediate layer, then further in accordance with【5】Extremely【9】The step of install the superiors；
So far, the manufacture of absorption tower body is completed.
