Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a jacket structure attached to the surface of a tank, and more particularly to a jacket structure for a tank surface suitable when the jacket is divided into a plurality of pieces.

[Conventional technology]

It has been conventional practice to heat or cool (hereinafter referred to as the term "heating") the stored material in the tank by attaching a jacket to the surface of the tank and passing a heating or cooling medium through the jacket. There is. An example is shown in FIG. This figure shows an example where the tank capacity is very large, and the jacket 12 is attached to a vertical tank by dividing it into multiple parts. The reason why the jacket 12 is provided in such a divided manner is that the temperature of the heating medium within the jacket can be more easily adjusted than with a single jacket, and uniform heating can be achieved. A heat medium supply pipe 14 and a discharge pipe 16 are connected to each jacket 12, respectively, with the supply pipe 14 converging on the outgoing main pipe 18, and the discharge pipe 16 converging on the returning main pipe 20. Both the outbound main pipe 18 and the return main pipe 20 are connected to a heat medium heating device 22 . Therefore, the heat medium heated by the heating device 22 may be transferred to the outgoing main pipe 18 or the supply pipe 14.
After being supplied to each jacket 12 and indirectly exchanging heat with the stored material in the link 10, the discharge pipe 16 is also returned to the heating device 22 via the return main pipe 20. By circulating the heat medium as described above, the stored material in the tank 10 is heated to a desired temperature or maintained at a constant temperature. For this purpose, the outer surfaces of the tank 10 and jacket 12 are covered with a heat insulating material (not shown), and the pipe system is also insulated.

By the way, when the jacket 12 is divided into a plurality of parts as described above, the heat medium supply pipe 14 and discharge pipe 16 connected to each jacket are arranged around the tank. Therefore, an area for piping is required around the tank.

Another drawback was that supporting the piping, painting it, and keeping it warm required time and effort.

[Problem that the invention seeks to solve]

The purpose of the present invention is to eliminate the drawbacks of the prior art described above, and to prevent piping from forming around the tank even when a jacket divided into multiple parts is attached to the tank surface (to save space around the tank). The object of the present invention is to provide a jacket structure for a surface that can be coated.

[Means for Solving the Problems] The jacket structure according to the present invention is such that at least a part of the heat medium supply part and the heat medium discharge part to the jacket, which is divided into a plurality of parts, crosses the jacket and contacts the tank surface. It is characterized by being provided with

[For production]

At least part of the piping that was conventionally connected to the jacket is now installed across the jacket and in contact with the tank surface.The heat medium supply section and heat medium discharge section have been replaced with a forest of piping around the tank. There's no need.

〔Example〕

Embodiments of the present invention are shown in FIGS. 1 to 3.

Tank 30 has multiple jackets) 40, 50.

60 are provided. Each jacket has a heating medium supply section 42
, 52.62 and a heat medium discharge part 44, 54°64. These heat medium supply section and discharge section are raised from below the tank 30, are provided in contact with the tank surface, and at least a portion thereof crosses the jacket. For example, the heat medium supply section 42 crosses the jacket 60 and the jacket 50 and is connected to the uppermost jacket 40. Further, the heat medium discharge part 42 is connected to the jacket 40, and after crossing the jacket 40 itself,
It traverses jacket 50 and jacket 60.

Inside each jacket, partition plates 46, 56 and 66 are provided to regulate the passage of the heat medium within the jacket. Further, a socket 70 is attached to one end of the heat medium supply section and the heat medium discharge section that is not connected to the jacket, and each heat medium supply section 42, 52, 62 is connected via these sockets 70.
to the outgoing main pipe 72 of the heating medium, and to each heating medium discharge section 44° 54
．． 64 is connected to the return main pipe 74 of the heating medium.

The heat medium supplied from the outgoing main pipe 72 of the heat medium passes through the socket 70 and is then delivered to each heat medium supply section 42 , 52 .

62, inside each jacket 40,50.60,
Flows in the direction of the arrow in FIG.
4, it reaches the return main pipe 74, passes through a heat medium heating device (not shown), and is used for circulation. According to this embodiment,
Heat medium supply part A2゜52.62 and heat medium discharge part 44.5
4.64 is provided in contact with the surface of the tank 300, so even while the heat medium passes through it, the tank 30
Indirect heat exchange with the reservoir within takes place and heats the reservoir. That is, the heat medium supply section and the heat medium discharge section share the same function as the jacket. Further, since these supply section and discharge section are provided across the jacket, the jacket, supply section, and discharge section are not stacked on the tank surface. Therefore, the protruding parts such as the jacket part on the tank surface can be maintained flat, making it easier to carry out heat insulation work, and also being aesthetically pleasing.

In the embodiment, the jacket and the heat medium supply section,
The discharge section is illustrated as having a structure in which a partition plate is provided for each adjacent heat medium passage. However, in such a structure, the shapes of the jacket, heat medium supply section, and discharge section that are manufactured in advance become complicated.

Further, there is a problem in that it becomes virtually impossible to join the tank body plate and the internal partition plate by welding or the like, and it is difficult to ensure the sealing performance of the heat medium passage. Therefore, in carrying out the present invention, an element 80 having a U-shaped cross section as shown in FIG. It is preferable to form. That is, as illustrated in FIG. 5, a straight element 82 with the above-mentioned cross section, a bent element 84,
The U-shaped element 86 and the like are appropriately combined to form a jacket, a heat medium supply section, and a discharge section.

These elements can be easily produced by press working, and can be given a radius of curvature that matches the tank body, if necessary.

The present invention is not limited to the above embodiments, but can also be applied to horizontal tanks. Further, the jacket does not necessarily require a partition plate to regulate the passage of the heat medium, and the jacket may be made completely flat. Alternatively, a steel or flexible plastic tube may be wound into a coil as the jacket, and the heat medium supply section and discharge section may also be constructed of tubes.

〔Effect of the invention〕

In the present invention, at least a part of the heat medium supply part and the discharge part connected to the jacket divided into a plurality of parts are provided across the jacket and in contact with the surface of the tank. There is no need to set up a series of pipes. Therefore, the support, heat insulation, and painting that were conventionally required for these pipes can be omitted, and the heat medium supply and discharge parts can be integrated with the tank and share the same heat exchange function as the jacket. .
