スペースが大きくなると共に、コストも嵩み、更に、機
関重量も増大するという問題があった。Conventionally, an exhaust economizer that uses the exhaust heat of high-temperature exhaust gas from an internal combustion engine to generate miscellaneous steam, etc.
As in No. 3-16998, these devices are usually formed separately from the exhaust muffler, which increases the space occupied by these devices, increases costs, and also increases the weight of the engine. was there.
また、上記排気エコノマイザと排気消音器とを継合する
排気ガス連絡管が必要となると共に、これらの機器など
の全表面積が大きくなり、それだけ放熱による熱損失が
大きくなるという問題もあった。In addition, an exhaust gas communication pipe is required to connect the exhaust economizer and the exhaust muffler, and the total surface area of these devices increases, which increases heat loss due to heat radiation.
更に、これら両機器それぞれに排気ガスドレン抜きが必

ようになっている。First, this exhaust economizer introduces exhaust gas G from the exhaust pipe of an internal combustion engine (not shown) and exchanges heat with a heat medium such as water W. Side lids 1 and 9 are attached to both ends of the main body 2 with bolts via gaskets 8, and the exhaust gas G of the internal combustion engine is passed from the gas port 1A provided in the center of one side lid 1 to the main body. It is designed to be introduced into a plurality of σ) tubes 5 disposed within the inner cylinder 2A of No. 2 via a partition plate 6.

に導出され、使用個所に供給されるようになっている。That is, the inside of the plurality of tubes 5 arranged in the inner cylinder 2A becomes a passage for the exhaust gas G, while the outside of the tube 5 in the cylinder 2A becomes a passage for the water W, and the heat between the exhaust gas G and the water W is absorbed. The water W enters the inner cylinder 2A along the water inlet 2C provided in the main body 2 along the A1 cutting plate 6, and after heat exchange, it enters the inner cylinder 2A along the f1 cutting plate B. The water is led out to the outside via the water outlet 2D and supplied to the point of use.

ス出ＬｌＩＢがら排出される。Next, the exhaust gas G introduced into the pipe 5 is transferred to the side lid 9.
It is folded back into a U-shape, passes through a space 2E formed by the outer periphery of the inner cylinder 2A of the main body 2, and the inner periphery of the outer cylinder 2B that is integrally provided with the outer periphery of the inner cylinder 2A, and reaches the side lid 1 side. The gas is discharged from the provided gas outlet LlIB.

るが、その個数は史に増加することもできる。Next, FIG. 2 is a side sectional view of the essential parts of an exhaust economizer in Embodiment 2 of the present invention, which has almost the same configuration and function as Embodiment 1 in FIG. 1, and the same parts are the same. Although it is indicated by the part number, a baffle plate 4A is installed in the exhaust gas G passage part of the space 2E formed by the inner cylinder 2A2 and the outer cylinder m2B.
and 4B, a multi-stage expansion type exhaust silencer is constructed.Furthermore, a ring portion 7 is integrally formed on the outer periphery of the inner cylinder 2A, which improves exhaust noise silencing effect and heat exchange efficiency. □ The above-mentioned baffle plate 4A is placed on the inner cylinder 2A side, and the baffle plate 4
B are integrally formed on the inner cylinder 2B side,
Although the exhaust gas G is made to meander through these, the number of them can be increased over time.
