As shown in the figure, the conventional shell and tube heat exchanger 10 for cooling the distilled water has a cylindrical shell 20 in which the steam inlet 22 and the distilled water outlet 24 are formed, respectively, and the middle part except the ends of both ends. Opening of the shell 20 while both ends of the refrigerant tube 30 and the refrigerant tube 30 installed inside the shell 20 are refracted in a U-shape to pass through the inside of the shell 20. The refrigerant tube sheet 40, the refrigerant inlet 52, and the refrigerant outlet 54, which are installed to block one end of each other, are respectively formed so that the refrigerant flowing through the refrigerant tube 30 flows in a predetermined direction. While being formed, the configuration includes the refrigerant tube head 50 provided on one side of the shell 20.

Meanwhile, in the conventional shell and tube heat exchanger 10 for cooling distilled water, both ends of each refrigerant tube 30 are joined to the refrigerant tube sheet 40 by welding, with the refrigerant tube sheet 40 interposed therebetween. Since the shell 20 and the refrigerant tube head 50 are installed in a bonded state, high purity distilled water cannot be obtained when wear occurs in the welded portion between the refrigerant tube sheet 40 and the refrigerant tube 30. There was a problem such as being. That is, when the welded portion between the refrigerant tube 30 and the refrigerant tube sheet 40 is damaged by wear or the like, the refrigerant flowing along the refrigerant tube 30 flows into the shell 20 and vapors in the shell 20. Or there is a risk of contaminating distilled water.

Hereinafter, with reference to the accompanying drawings, the configuration and operation state of the shell and tube heat exchanger for distilled water cooling according to an embodiment of the present invention will be described in more detail.

Reference numeral 100 denoted in the drawings indicates a shell and tube heat exchanger for cooling distilled water according to an embodiment of the present invention.

Distilled water cooling shell and tube heat exchanger 100 according to an embodiment of the present invention is a cylindrical shell 110 provided with a steam inlet 112 and a distilled water outlet 114, bent in a U-shape of the shell 110 The refrigerant tube 120 installed inside, the refrigerant tube sheet 130 to which both ends of the refrigerant tube 120 are coupled, and the refrigerant inlet 142 and the refrigerant outlet 144 are provided, respectively. It is configured to include a refrigerant tube head 140 formed.

In particular, one end of the shell 110, which is open for assembly installation of the refrigerant tube 120 in the shell-and-tube heat exchanger 100 for distilled water cooling according to an embodiment of the present invention, is an end cover 150 that is separately manufactured. Will be closed.

On the other hand, the refrigerant tube sheet 130, which is coupled to both ends of the refrigerant tube 120 is assembled and installed at a predetermined distance from the end cover 150, the end cover 150 and the refrigerant tube sheet 130 Some sections of the coolant tube 120 positioned therebetween form a structure exposed to the outside of the shell 110.

As described above, in the shell and tube heat exchanger 100 for cooling the distilled water according to the embodiment of the present invention, the end cover 150 installed at one end of the shell 110 and the refrigerant tube sheet 130 are spaced apart. The main reason for the separated structure is that both ends of the refrigerant tube 120 are bonded to the refrigerant tube sheet 130 by welding, so that the welding is less affected by the welding, and further, the joining of the joint portions. This is to keep the state more robust.

In addition, while the shell-and-tube heat exchanger 100 for cooling the distilled water according to the embodiment of the present invention is worn or damaged by the joint between the refrigerant tube sheet 130 and the refrigerant tube 120 by mutual welding. In order to prevent the refrigerant from passing through the refrigerant tube 120 into the inside of the cell 110 through which steam or distilled water passes, even if leakage of the refrigerant occurs.

The seal ring 160 is installed on the inner side and the outer side of the end cover 150 to which the refrigerant tube 120 is in contact so as to be maintained. On the other hand, the inner seal plate 170 and the outer seal plate 172 are fastened and mounted through the fastening means 180 or the like on the inner side and the outer side of the end cover 150 so that the state in which the seal ring 160 is installed can be maintained. Becomes

As described above, the inner seal plate 170 and the outer seal plate 172 are installed inside and outside the end cover 150, and as a result, the refrigerant tubes 120 are more stable to the end cover 150. The assembled state can be maintained. In addition, the gap between the inner circumference of the tube installation hole 152 formed in the end cover 150 and the outer circumference of the refrigerant tubes 120 may be more closely sealed.

On the other hand, the refrigerant tube head 140 is fixedly mounted through a fastening means such as a bolt and a nut with a packing in between the refrigerant tube sheet 130.

Hereinafter, the operation of the shell and tube heat exchanger 100 for distilled water cooling according to an embodiment of the present invention will be described briefly.

Distilled water cooling shell and tube heat exchanger 100 according to an embodiment of the present invention is to be installed in a process that allows the steam changed from the raw water to the gas state through a predetermined process to be changed back to the liquid state.

That is, the gaseous vapor is input through the steam inlet 112 provided in the shell 110 of the shell and tube heat exchanger 100 for distilled water cooling according to an embodiment of the present invention, and passes through the refrigerant tube 120. The distilled water whose phase is changed into a liquid state through heat exchange with the refrigerant is discharged to the outside through the distilled water outlet 114 provided under the shell 110. As described above, the refrigerant input through the refrigerant inlet 142 passes through the refrigerant tube 120 installed inside the shell 110 and then is discharged through the refrigerant outlet 144.

On the other hand, in the shell and tube heat exchanger 100 for cooling the distilled water according to the embodiment of the present invention, the end cover 150 and the refrigerant tube sheet 130 have a predetermined spaced apart structure. Therefore, the end cover 150 assembled at one end of the shell 110 is not affected in the process in which both ends of the refrigerant tube 120 are bonded to the refrigerant tube sheet 130 by welding.

In particular, even if damage such as abrasion occurs in the welded portion between the refrigerant tube sheet 130 and the refrigerant tube 120, the steam or distilled water passing through the shell 110 is not affected. That is, even if the leakage of the refrigerant flowing along the refrigerant tube 120 is not mixed with the steam or distilled water passing through the shell 110, it is still possible to obtain a high-purity distilled water in the event of a failure.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention.
