- This is a structure before the upper end chamber 34a, the upper tube plate 23a, the liquid distributor 38, etc. provided with the concentrating section liquid inlet 28 and the concentrating section steam outlet 29 are disposed inside the main body cylinder 21.
- a plurality of cutting tubes 35 are arranged.
- the lower body Ha of the internal heat exchange distillation column can be assembled, for example, in a state where the main body cylinder 21 is placed horizontally, and can be assembled with high accuracy.
- the lower body Ha of the internal heat exchange distillation column is vertically set up, and a pipe / filling unit A serving as a distillation section is inserted into each of the plurality of partition pipes 35 from above.
- the internal heat exchange type distillation column of the invention of the present application is configured so as to constitute a distillation section by inserting the tube-filling unit A into the partition tube 35, so that the tube
- the pipe 1 constituting the packing unit A is each pipe constituting a plurality of pipes of the internal heat exchange distillation column
- the inside of the pipe 1 is the inside 24 of the internal heat exchange distillation tower H
- the outside of the pipe 1 Is the outside 25 of the internal heat exchange distillation column H
- the inner regular packing layer 2 constituting the pipe / packing unit A is used as the regular packing layer 2 of the inner pipe 24 to form the pipe / packing unit A. It is possible to easily and reliably realize the structure in which the outer regular packing layer 3 is the outer packing layer 25 outside the tube.
- the inner regular packing layer 2 is disposed on the inner side of each pipe 1 constituting the plurality of pipes, and the outer side of each pipe 1 is surrounded so as to surround the outer peripheral surface.
- the regular packing layer 3 is disposed, and the outer regular packing layer 3 disposed on the outer peripheral surface of each pipe has a structure in which each pipe 1 is covered with a partition pipe 35 made of a thin metal plate.
- a plurality of single tube units 40 are arranged inside the main body cylinder 21 at a predetermined pitch, and the high pressure on the 24 side in the tube is set by using the tube wall of each tube 1 constituting the multiple tubes as a heat transfer surface.
- the internal heat exchange distillation column H is constructed so that the high pressure side on the 24 side in the tube functions as the concentrating unit and the low pressure side on the 25 side outside the tube functions as the collecting unit by transferring heat from the side to the low pressure side on the 25 side outside the tube. Can be manufactured efficiently.
- the distillation section is formed by inserting the tube / filling unit A into the cutting tube 35. For this reason, the tube-filling unit (distilling section) A can be easily removed from the partition tube 35 or inserted into the partition tube 35, so that the tube-side packing can be easily detached.
- Example 2 the internal heat exchange distillation column having a structure in which a plurality of single tube units 40 are arranged inside the main body cylinder 21 at a predetermined pitch (that is, the inside of the main body cylinder).
- the internal heat exchange distillation column with a plurality of pipes was described as an example, but the internal heat exchange distillation column having a structure in which one single pipe unit is disposed inside the main body cylinder, that is, the main body
- the internal heat exchange has a structure in which one single pipe unit is disposed inside the main body cylinder.
- this internal heat exchange-type distillation column is made into one distillation unit, and if necessary, the number of distillation units can be increased to flexibly cope with an increase in throughput. .
- the tube-filling unit of the present invention integrally includes a tube, an inner ordered packing layer disposed inside the tube, and an outer ordered packing layer disposed outside the tube.
- a single pipe or multiple pipes are connected to the main body cylinder by a double-sided tube plate to isolate the inside of the single pipe or each pipe from the inside of the main body and the outside of the pipe.
- a packed column type internal heat exchange distillation column in which the operation temperature is varied by making a difference in the operation pressure and heat is transferred from the high pressure side to the low pressure side by heat transfer. It can be suitably used as a constituent member of the distillation section.
- the distillation section (that is, the tube / filling unit of the present invention) can be extracted and easily cleaned, and good distillation performance can be reliably maintained.
- a heat exchange performance inside and outside the tube energy saving performance as a whole, and an internal heat exchange distillation column with excellent distillation performance are provided. Deliver power S.
- the tube-packing unit and the internal heat exchange distillation column of the present invention can be widely used in various fields, and in particular, liquids that require regular cleaning of the distillation section.
