うに流れることもある。 FIG. 2 shows an example in which the heat exchanger according to the present invention is installed in a combustion furnace, for example, boiler A. That is, heat exchanger E is installed in chimney A' of boiler A.
is installed via a droplet collecting plate 6, and the entire body is covered with an outer shell 7. In this case, the plurality of tubes 2, 2 arranged in parallel and spirally wound around the cylindrical body 1 are in close contact with each other,
In addition, the cylindrical body 1 and the tubes 2, 2 are in close contact with each other so that no fluid passes through them, and furthermore, the plurality of tubes 2, 2 wound spirally with a gap R on the outside thereof are in close contact with each other,
In addition, the tube 2 and the inner wall of the outer shell 7 are in close contact with each other, so that no fluid passes therethrough. Therefore, when the exhaust gas from the boiler A flows upward as shown by the arrow and enters from the exhaust gas inlet 5 of the cylindrical body 1, this gas adheres tightly to the cylindrical body 1 and spirals. It flows straight through the gap R between the tubes 2, 2 wound in a spiral manner and the tubes 2, 2 in close contact with each other on the outside as shown by the arrow F, and the tubes 2, 2 (in a cylindrical shape In both the tube wound around the body 1 and the tube wound outside with a gap R, the exhaust gas flows in the spiral shape shown by the arrow, and the pressure of the exhaust gas is increased as necessary. Depending on the situation, the water may flow inside the cylindrical body 1 as shown by the arrows by opening and closing the damper 4.

スが滞留するようなことはなくなる。 In the heat recovery device using the heat exchanger according to the present invention having this configuration, first, the water W is supplied to the water supply section 9 so that the water W is brought into close contact with the cylindrical body 1, and is then spirally wound in parallel. It flows through a plurality of closely spaced pipes 2, 2 arranged in parallel and a plurality of closely spaced pipes 2, 2 arranged in parallel and spirally wound with a gap R between them to reach the drainage section 10, but the water is discharged from the boiler A. Hot gas inlet 5
The more inflowing exhaust gas flows straight through the gap R as shown by the arrow F, or flows spirally as shown by the arrow. However, when the furnace pressure of the exhaust gas of boiler A is high, the exhaust gas flows smoothly as explained above, becomes lower in temperature from the cover 7' at the top of the outer shell 7, and is diffused into the outside world. However, when the furnace pressure of boiler A is low, the exhaust heat gas flows to a certain extent through the gap R; In addition, in any case where a gap R is provided and the pipe is wound around the outside of the pipe, the exhaust heat gas flowing below has a spiral shape and the flow becomes very poor, so by opening the damper 4 of the cylindrical body 1 Adjust the air volume to improve the flow of exhaust gas. Therefore, since the exhaust gas flows in the cylindrical body 1 as shown by the arrow, there is no possibility that the exhaust gas remains in the spiral tubes 2, 2.

つて、覆７′から外界へ拡散される。 In this way, the exhaust gas flows through the gap R, the spiral-shaped closely connected tubes 2, 2 (both the tube wound around the cylindrical body 1, and the tube wound around the outside with the gap R). While flowing on the lower side, sometimes inside the cylindrical body 1, the spiral tubes 2, 2 (both in the tubes wound around the cylindrical body 1 and in the tubes wound on the outside with a gap R) The water flowing through the combustion furnace (boiler) A exchanges heat with the high-temperature exhaust gas from the combustion furnace (boiler) A.
The water flowing into the tank reaches a temperature of approximately 80 to 90°C and is discharged H, while the exhaust gas has a low temperature of about 50°C and is diffused from the cover 7' to the outside world.
このように、本発明に係る熱交換器は高温の排
熱ガスと螺旋状の管との接触面積が極めて大きい

大きく、従つて、排水の温度は高温で、かつ、排
熱ガスの温度は極めて低温となる。 As described above, in the heat exchanger according to the present invention, since the contact area between the high temperature exhaust gas and the spiral tube is extremely large, the heat exchange rate between the exhaust gas and the water in the spiral tube is also large. , the temperature of the waste water is high and the temperature of the exhaust heat gas is extremely low.

８に入りパイプＰより外部へ流されていく。 In addition, FIG. 4 is a schematic diagram of the water supply section and the drainage section. In the case of water supply, water from the pipe P enters the water receiving section 8, and then flows through a plurality of closely spaced pipes 2 arranged in parallel in a spiral shape. . High-temperature water from the plurality of pipes 2 arranged side by side (both the pipes wound around the cylindrical body 1 and the pipes wound around the outside with a gap R) enters the water receiving part 8. It flows out from pipe P.

という優れた効果を奏する。 As explained above, since the heat exchanger according to the present invention has the above-mentioned configuration, the heat exchanger according to the present invention has a structure in which the exhaust gas and the cylindrical body are closely wound in a spiral manner and arranged in close contact with each other in parallel. The heat exchange rate is also large because the contact area between the multiple tubes and the multiple tubes that are spirally wound and arranged in parallel with gaps on the outside is extremely large, and the gap is also large when it comes to the cylindrical body. Because it is located between the helical tube that is in close contact with the outside of the helical tube and the spiral tube that is in close contact with the outer side of the helical tube, the exhaust gas can be smoothly diffused to the outside world regardless of the pressure of the exhaust gas from the combustion furnace. be effective.
