トし、ボルト（図示せず）を締結する。Next, a method of connecting the upper end of the pipe 25 to the top-side tube sheet 3a will be described. Here, FIG.
As shown in (2), the lower end of the tube 25 in which the distillation unit is disposed is fixed to the bottom tube plate 3b, and the distillation unit is installed outside the tube in a state where the tube 25 is set up substantially vertically. Outer distributor 6a
After mounting, the steps after the step of disposing the top-side tube sheet 3a will be described. The top-side tube sheet 3 a is placed at a predetermined position on the upper part of the main body 1. At this time, the upper end of the pipe 25 fits into each through-hole 21 of the tower-side tube sheet 3a. The through-hole 21 of the top-side tube sheet 3a is sufficiently larger than the outer diameter of the tube 25. Through-hole 41 in tower tube 3b
Is the outer diameter of the tube 25 + 1 mm to determine the position of the tube 25
The through-hole 21 of the top-side tube sheet 3a is
Outside diameter + about 15 mm. This means that the length of the tube 25 is 1
This is because the length is often 0 m or more, and the center of the column at the top of the column is not necessarily vertically above the center of the column at the bottom of the column. In addition, in the internal heat exchange type distillation column, pipes 2
More often, the diameters of 5 are different. The top-side tube sheet mounting member 22 may be welded to the upper flange portion 1a of the main body 1 in advance, or after the top-side tube sheet 3a is placed, the top-side tube sheet is attached. The attachment member 22 may be welded to the flange portion 1a of the main body 1. In addition, the top tube plate is installed first according to the test method for conducting the pressure test of the internal heat exchange type distillation column body at the manufacturing plant, the transportation method to the installation location, the certification method of the tower verticality at the time of installation on site, etc. If the member 22 is welded, it may hinder testing, transportation, or recognition of verticality, but it is desirable to perform welding in advance in order to shorten the on-site construction period. Therefore, it is desirable to determine the mounting time of the tower-side tube sheet mounting member 22 in consideration of the above various circumstances.
Next, on the contact surface between the top-side tube sheet 3a and the upper flange portion 1a of the main body 1, a flange portion 31a of the top cover 31 is provided.
And a jig such as a vise, applying a contact pressure similar to that applied when the upper flange portion 1a of the main body 1 is bolted. The top tube sheet 3a is seal-welded. Then, the pipe connecting member 24
Is attached to each of the tubes 25 one by one. And
The pipe connecting member 24 and the tower-side tube sheet 3 are seal-welded, and the pipe connecting member 24 and the pipe 25 are seal-welded. Thereafter, the jig such as the vise used above is removed, and the tower top reflux distributor 8a (FIG. 1 (a)) is attached. Then, the top cover 31 is set via the packing 26, and bolts (not shown) are fastened.
