Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a partition chamber of a relatively small-diameter heat exchanger having a number of circulations of two or more.

In a heat exchanger having two or more circulations, a partition chamber having a plurality of subchambers is provided adjacent to the tube sheet.

Conventionally, each of the partition plates constituting this division is abutted on a bracket welded to the inner surface of the partition via a gasket, and is attached by bolting.

Therefore, the partition plates must be assembled inside the partition room, and if this is applied to a small heat exchanger, it will be difficult to work, and it will be difficult to perform repairs or internal inspections in the event of an accident such as damage to a heat exchanger tube. It will also be difficult.

The present invention solves the above-mentioned drawbacks by configuring each partition wall as an integrated partition box that can be attached to and removed from the partition chamber.One embodiment of the invention will be described below with reference to the drawings.

Reference numeral 1 denotes a cylindrical main body container, inside which a large number of heat transfer tubes 2a,
2b are arranged in parallel.

Both ends of the heat exchanger tubes 2a, 2b are open to a tube plate 3 that closes both ends of the main body container 1, and a partition chamber 4 is provided adjacent to the tube plate 3.

A heat medium outlet 5 is provided near one end of the peripheral wall of the main body container 1, and an inflow port is provided near the other end.

A large number of baffle plates 6 are arranged in the main container 1 between the outflow port 5 and the inflow port to uniformly disperse the heat medium.

Each baffle plate 6 is supported by a bar 7.

The partition chamber 4 is configured in a cylindrical shape, and a lid body 9 is removably provided with a bolt 10 via a gasket 8 on a wall surface facing the tube plate 3 .

11 is a hanging member provided on the lid body 9.

The peripheral wall of the partition chamber 4 has an inlet 12 and an outlet 1 for the heat medium.
3 is provided.

14 is a partition box placed in the lower half of the partition 4;
It has a semicircular cross-sectional shape and is open at one end.

The opening edge of the partition box 14 is in contact with the bottom surface of the groove provided in the tube sheet 3 via a sealing material 15, and half of the heat exchanger tubes 2a that are open to the tube sheet 3 are opened into the partition box 14. .

A communication port 25 communicating with the inlet 12 of the partition chamber 4 is formed by a short tube 26 in the bottom wall of the partition box 14 .

The tip of the short tube 26 is in contact with the inner surface of the partition chamber 4 via a sealing material 27.

Brackets 16 are provided on both sides of the upper surface of the partition box 14, and the brackets 16 are fixed by bolts 18 that are screwed into threaded holes in brackets 17 protruding from the peripheral wall of the partition chamber 4.

Reference numeral 19 denotes a turn baffle type pressing device disposed between the center of one end of the upper surface of the partition box 14 and the peripheral wall of the partition chamber 4.

The pressing device 19 consists of a threaded cylinder 20, a fixed bolt 21 and a movable bolt 22 screwed into the threaded cylinder 20.

Both poles 21 and 22 have thread grooves in opposite directions.

The fixed bolt 21 is fixed to the partition box 14 by welding, and the movable bolt 22 is formed in a T-shape.

The threaded cylinder 20 has a hexagonal cross section.

23 is a handle provided on the partition box 14; 24 is the partition box 14;
This is a spacer fixed to the

According to such a configuration, two compartments 24 a and 24 b are formed in the partition chamber 4 by the inside and outside of the partition box 14 , and the two compartments 24 a and 24 b are formed inside the main body container 1 via the heat transfer tubes 2 a and 2 b. A circulating flow path is formed.

Then, heat exchange is performed between the medium flowing through the flow path and the medium flowing inside the main body container 1.

The tip of the short tube 26 constituting the communication port 25 of the partition box 14 comes into contact with the periphery of the inlet 12 of the partition chamber 4 via the sealing material 27, and is pressed by the pressing device 19, so that the contact part is securely pressed. A seal is obtained, and both compartments 24a, 24
The medium will not be short-circuited between b.

When repairing and inspecting the inside of the partition 4, remove the lid 9, rotate the threaded cylinder 20, and tighten the movable bolt 22 into the partition 4.
and the bolts 18 of the brackets 16 and 17 are loosened.

In this manner, the partition box 14 is taken out from the partition chamber 4, and various operations such as cleaning of the openings a of the heat exchanger tubes 2a and 2b opened in the tube plate 3 are performed inside the enlarged partition chamber 4.

When reassembling, place the partition box 14 inside the partition chamber 4 in the opposite manner to the above, and tighten the bolts 18 (brackets) 16.17.
The assembly is completed by fixing and tightening the threaded cylinder 20.

In this way, since the partition box 14 can be attached and detached, the partition box 14 can be attached and detached.
branch room 24a.

Unlike a structure in which each partition wall that partitions between 24 and 24b is constructed separately, assembly and disassembly work is simple, and repairs and inspections inside the partition wall 4 can be easily performed.

Further, since the partition box 14 is pressed by the pressing device 19, a seal between the communication port 25 of the partition box 14 and the inflow port 12 of the partition chamber 4 can be reliably obtained.

As explained above, according to the present invention, each partition wall forming a separate room within a partition room is constructed from an integrated partition box, so the structure inside the partition room is simple and assembly and disassembly are easy. , repairs and inspections inside the partition can be easily carried out.

In addition, since the partition box is configured to be pressed against the inlet or outlet of the peripheral wall of the partition chamber using a pressing device, a reliable seal can be obtained at the connection between the inlet and the outlet, and there is no problem of short circuits of the medium. .
