Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preventing heat intrusion to prevent temperature rise inside a tank due to solar radiation during tank construction.

Conventionally, when constructing tanks in the summer or in hot regions, the temperature inside the tank becomes extremely high due to solar radiation on the tank roof and side panels, making the working environment inside the tank poor. Conventionally, therefore, a method has been generally used to cool the tank by pouring water on it, but such a method has various drawbacks because it requires a large amount of water.

Therefore, an object of the present invention is to provide a method for preventing heat intrusion during construction of a tank, which eliminates such conventional drawbacks and suppresses temperature rise inside the tank.

According to this invention, a method for preventing heat intrusion during construction of a tank is to cover the solar radiation area of the tank roof and tank side panels with a sheet that does not allow light to pass through, such as cloth, to block solar radiation, and to spray water onto this sheet. The process consists of impregnating or retaining the water to suppress the temperature rise inside the tank due to the heat of vaporization of the water.

Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

1 and 2 of the drawings show an embodiment of the method for preventing heat intrusion during tank construction according to the present invention. In the method of preventing heat intrusion according to the present invention, first, a light-blocking sheet 3, such as cloth or a combination of cloth and a waterproof sheet, is attached to the tank side plate/solar area. The seat 3 is attached by hanging it from the outer periphery of the walkway or handrail provided on the upper part of the side plate 1, and fixing the lower end to the bottom of the tank as appropriate. Next, a plurality of support members J, such as a ring-shaped pipe B with legs, are attached concentrically or at appropriate intervals on the tank roof, and on top of these support members S are placed the side plates/tops. Stretch a sheet 1-t made of the same material as the installed sheet 3. As shown in FIG. 2, this sheet t has a hook-like stopper 9 on its upper edge, and is fixed by hooking this hook-like stopper D onto the pipe B of the support member S. It has become so. The lower end of the sheet g is stacked on top of the upper end of the adjacent sheet g and fastened with wire, etc., and the lower end of the sheet g at the outer periphery of the tank roof is left hanging from the outer periphery and a weight is attached. Alternatively, it may be secured to the side plate/top sheet 3 with wire to prevent it from curling up. Sheet 3. Spray water on g and allow it to impregnate or stay there. thus,
Sheets J and g block sunlight, and sheet 3. The latent heat of vaporization of water on the surface removes the heat that reaches the tank, preventing heat from entering the tank.

Another embodiment of the method for preventing heat intrusion according to the present invention is shown in FIG. The sheet 31 on the side plate l of this embodiment is attached to a hanging device 10, and this hanging device /θ
The tank has a rail provided at the upper end of the side plate so as to be able to move along the outer periphery of the tank, or a roller that rolls on a handrail of a circumferential walkway. In this way, the sheet 31 attached to the hanger /θ can be moved as the solar radiation direction changes, so the area of the sheet 31 can be minimized.

Further, in the first and first embodiment 1, the sheet 3
9g and the tank to improve ventilation, the effect of preventing temperature rise is improved. Even when installed in a solar-irradiated area, the amount of heat entering the tank can be significantly reduced compared to conventional systems. Furthermore, if the solar radiation is weak, sheet 3. Of course, temperature rise can be suppressed even without supplying water to S.

As described above, according to the present invention, a sheet made of opaque cloth or the like is stretched over the solar radiation area on the tank to block solar radiation, and the heat of the tank is taken away by the heat of vaporization of the water impregnated or retained in the sheet. This simple method can significantly prevent heat from entering the tank and improve the working environment inside the tank. Further, the amount of water supplied to the sheet is sufficient to moisten the surface of the sheet, and the cost of water is low.
