Abstract

(57) [Summary] [Purpose] The space between the heat insulating material and the heat transfer member that penetrates the heat insulating material can be shielded from the outside air. [Structure] A collar 5 that contacts the outer surface of the heat insulating material 3 is formed on a heat transfer member 2 that penetrates the heat insulating material 3 that covers the outer wall 1a of the container 1 and is attached to the outer wall 1a of the container 1 with its tip in contact. It has a feature.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container outer wall mounting device for a heat transfer member which is mounted in contact with a large container such as a reactor container or a steam generator.

[0002]

[Prior art]

 For example, when a heat transfer member 2 such as a preheater heater is attached to the outer wall 1a of the container 1 as shown in FIG. 2, the heat transfer member 2 has its tip attached to the outer wall of the container 1 and its rear portion attached to the container 1. The heat insulating material 3 covering the outer wall of the container is penetrated and connected to a power source. At that time, between the outer wall 1a of the container 1 and the heat insulating material 3 and between the heat transfer member 2 and the heat insulating material 3, strictly during initial processing, The space 4 is formed even if the construction is performed.

[0003]

[Problems to be solved by the device]

 This space becomes large due to the displacement of the outer wall of the container and the heat insulating material caused by the thermal expansion when the temperature of the equipment rises, and this large space causes the outside air to flow in and out due to the chimney effect, significantly deteriorating the heat insulating performance. The present invention has been developed to address such a problem, and an object thereof is to shield the space between the outer wall of the container and the heat insulating material covering the same from the outside air.

[0004]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to FIG. 1 corresponding to an embodiment. In the present invention, the heat insulating material 3 covering the outer wall of the container 1 is penetrated to the outer wall of the container 1. It is characterized in that the heat transfer member 2 attached in contact with is formed with a collar 5 which contacts the outer surface of the heat insulating material 3.

[0005]

[Action]

 Further, according to the present invention, the collar formed on the heat transfer member by the above means blocks the space between the heat transfer member and the heat insulating material from the outside air to prevent the outside air from flowing in and out.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1. The drawing shows a case where a preheat heater 2a and a thermocouple well 2b as a heat transfer member 2 are attached to an outer wall 1a of a container 1, and the preheat heater 2a is A heat insulating material 3 for bending the tip and fitting the bent portion closely along the outer wall 1a of the container 1 and for covering the outer wall 1a of the container 1 at the rear portion, and a covering material 3a for covering the heat insulating material 3 Through the space 4 and a flange 5 that contacts the outer surface of the heat insulating material 3 is formed in the space 4 and the well 2b for thermocouple has its tip abutted on the outer wall 1a of the container 1 and The heat insulating material 3 and the covering material 3a were pierced through the heat insulating material 3 and the covering material 3a with a space 4 therebetween, and a flange 5 was formed in the penetrating portion so as to be in contact with the outer surface of the heat insulating material 3. Reference numeral 6 in the figure denotes a thermocouple inserted in the thermocouple well 2b.

Thus, the space 4 between the outer wall 1a of the container 1 and the heat insulating material 3 and the space 4 between the heat insulating material 3 and the heat transfer member 2 become large due to thermal expansion displacement or the like, and the container 1 is heated to a high temperature. Then, the chimney effect of this space tries to let the outside air in and out, but at this time, the collar 5 provided in the heat transfer member 2 blocks the inlet of the space 4 to increase the flow resistance, thereby suppressing the chimney effect. The deterioration of heat retention performance can be prevented.

[0008]

[Effect of device]

 As described above, according to the present invention, the heat transfer member, which penetrates the heat insulating material covering the outer wall of the container and is attached to the outer wall of the container with the tip thereof in contact with the outer surface of the heat insulating material, is formed with the flange. Since the space between the heat insulating material and the heat insulating material is closed by the collar, the chimney effect of the space can be suppressed, so that the heat insulating performance is not deteriorated.
