ッダー、２８は空気弁である。2. Description of the Related Art Generally, a heat medium economizer is used as a waste heat recovery device for recovering heat from exhaust gas generated in a main engine (diesel engine) of a ship. By the way, in recent years, low-quality heavy oil (C
Heavy oil) is often used as a fuel, so the exhaust gas contains a large amount of soot and dust. As a result, there is a problem that a large amount of soot dust in the exhaust gas adheres to the heat transfer tubes of the heat medium economizer of the ship, and the heat exchange efficiency of the heat medium economizer is significantly reduced. In order to prevent this, the heat medium economizer is provided with a soot blowing device for injecting a cleaning fluid into the heat transfer tube in order to remove soot dust adhering to the heat transfer tube. Air or water is used as the cleaning fluid for the soot blowing device in the heat medium type economizer of a ship because there is no vapor source. FIG. 6 is a schematic vertical sectional view of a heat medium economizer 22 provided with a conventional pneumatic soot blowing device 21. The heat medium economizer 22 is a casing provided in a duct 23 through which exhaust gas G flows. A plurality of heat transfer tubes 25 with fins are arranged side by side in 24, and heat is exchanged between the exhaust gas G flowing in the casing 24 and the heat medium flowing in the heat transfer tube 25. or,
The soot blowing device 21 injects the compressed air A from the injection pipe 26 disposed in the casing 24 toward the heat transfer pipe, removes the soot dust adhering to the heat transfer pipe 26, and prevents the heat exchange efficiency from decreasing. Has been done by. Incidentally, in FIG. 6, 27 is a header and 28 is an air valve.

設ける必要がある等、様々な問題が発生する。However, the soot-blowing device 21 that uses compressed air A (about 7 kg / cm 2 ) as a cleaning fluid has the advantage that soot-blowing can be performed even when the main engine is operating, but only compressed air is available. However, it is difficult to completely remove the soot and dust adhering to the heat transfer tube 25, and the soot and dust adhering may gradually grow. As a result, not only the heat exchange efficiency is lowered, but also the ventilation resistance is increased and the fuel consumption of the main engine is increased. On the other hand, in a soot blowing device that uses water as a cleaning fluid, it is necessary to stop the main engine each time the soot is blown, and there is a problem that it cannot be used during voyage. In addition, there are various problems such as waste water treatment and a large-capacity heat medium economizer requires a large amount of washing water, and therefore a large-capacity washing drainage storage tank must be provided onboard. appear.

のある廃熱回収装置と同様に良好な煤吹きを行える。When soot and dust in the exhaust gas discharged from the main engine (diesel engine) adhere to the heat transfer tube of the heat medium economizer, compressed air and fresh water are supplied to the mixing nozzle of the soot blowing device. Then, the fresh water is atomized by the compressed air in the mixing nozzle, mixed with the compressed air, and supplied to the injection pipe. The mixed fluid supplied to the jet pipe is jetted from the nozzle hole of the jet pipe toward the heat transfer pipe, and blows out the dust particles adhering to the heat transfer pipe. This soot blowing device atomizes fresh water with compressed air, mixes it with compressed air and injects it into the heat transfer tube to remove soot and dust, so it can efficiently remove soot and dust as compared to the air type. . Further, the atomized fresh water evaporates in the high temperature exhaust gas after removing the soot and dust, so that the soot can be blown even while the main engine is operating, and the waste water treatment is not necessary. Furthermore, since the fresh water becomes a vapor and is injected from the injection pipe, the soot can be satisfactorily blown even by the waste heat recovery device without the steam source, like the waste heat recovery device with the steam source.

When the soot dust in the exhaust gas G discharged from the main engine during the voyage of the ship adheres to the heat transfer pipe 7 of the heat medium economizer 1, the soot blowing device 2 is periodically operated. That is, the air valve 19 is opened and compressed air A (about 7 Kg / cm 2 ) is supplied to the air pipe 14. Next, the fresh water cock 20 is half-opened, and fresh water W (pressure 2-3 Kg / cm 2 ) is supplied to the fresh water pipe 17. Then, the fresh water W ejected from the fresh water spray port 15 of the fresh water pipe 17
Is atomized by the compressed air A in the mixing nozzle 12, mixed with the compressed air A, and supplied to the injection pipe 11.
Then, the mixed fluid supplied to the injection pipe 11 is
The soot and dust that is ejected from the nozzle hole 10 of No. 1 toward the heat transfer tube 7 and adheres to the heat transfer tube 7 is blown away. The amount of fresh water is
It is adjusted by the fresh water cock 20 and is set so as to evaporate in the exhaust gas G. The soot blowing device 2 atomizes the fresh water W with the compressed air A, mixes it with the compressed air A, and injects it into the heat transfer tube 7 to remove the soot. Therefore, the soot blowing efficiency is higher than that of the air type. Can be removed well. Further, the atomized fresh water W evaporates in the exhaust gas G at a high temperature (usually 300 ° C. to 400 ° C.) after removing the soot and dust, so that the soot can be blown even while the main engine is operating and there is no need for wastewater treatment . Furthermore, since the fresh water W becomes a vapor and is ejected from the injection pipe 11, even a waste heat recovery apparatus without a steam source can perform good soot blowing as with a waste heat recovery apparatus with a steam source. Needless to say, the pressure of the fresh water W does not have to be increased, and the fresh water pressure in the ship can be used as it is, which is extremely convenient.
