している。[Jubei's shell and tube heat exchanger] High temperature and high pressure (
In a shell-and-tube heat exchanger that uses gas at approximately 1000°C (approximately 45 to 97 cm2) as an internal fluid, the strength of the pressure vessel body and high-temperature, high-pressure gas supply pipe stand will decrease as the temperature increases. A heat insulating material is installed on the inner surface of the main body and the nozzle stub, and a cooling jacket surrounding the pressure vessel from the outside is provided to maintain the temperature of the pressure vessel body and the nozzle below an allowable value.

High-temperature, high-pressure gas (helium gas) is supplied to the helium inlet nozzle 1.
The high temperature helium gas pipe 12 is led into the pressure vessel main body 2. The helium gas that has entered the pressure vessel main body 2 flows in the direction of the arrow through the gas passage partitioned by the jamb plate 6, gives heat to the heat transfer tube 4, lowers the temperature from the top, and passes through the helium outlet tube holder 5 to reduce the pressure. It is guided to the outside of the container.

かれる。なお、第１図において、１３は断熱材である。The water that enters the water supply inlet header 7 via the inlet water pipe header 6 passes through the heat exchanger tube 4 and receives no heat from the high temperature gas (helium gas), becoming a mixture of air and water, and passes through the air and water outlet header. 8 to the outside of the pressure vessel. The cooling water that has entered the cooling water inlet nozzle 10 rises inside the cooling jacket 9 while cooling the pressure vessel main body 2, and is led to the outside via the cooling water outlet nozzle 11. In addition, in FIG. 1, 13 is a heat insulating material.

因となる。In the conventional heat exchanger mentioned above, the cooling water flows smoothly from the bottom to the top inside the cooling jacket of the pressure vessel main body, but the helium inlet and outlet tube holders are installed horizontally, so the cooling water does not flow smoothly. Difficult to flow. Therefore, the length of the cooling jacket of this nozzle stub is kept short, and as a result,
It has the disadvantage that the temperature of the nozzle stub increases. In addition, if the cooling jacket of the nozzle holder is lengthened while ignoring the flow of cooling water, the cooling water will stagnate and stop flowing over the entire surface of the nozzle holder, causing uneven temperature distribution on the nozzle holder and causing thermal stress. becomes.
