ている。2. Description of the Related Art Conventionally, a water jacket is provided for a water-cooled flue gas cooler provided in a furnace body of an incinerator or a flue connected to the furnace body in order to use water as a refrigerant. In addition, the water vapor generated in the water jacket does not come into contact with the exhaust gas from the incinerator and does not contain any pollutant components, and thus is discharged to the atmosphere through a steam chimney. However, the water vapor released into the atmosphere looks dark when the sky is dark, such as when it is cloudy or at dusk, giving the impression that smoke is coming out of the incinerator. May cause anxiety that smoke is coming out of the water. Such problems can be solved by conventional techniques, such as a method of cooling water vapor to condense water droplet components in the water vapor and remove it as water,
It is known that this can be solved by further heating the steam to completely evaporate the water droplets in the water vapor so that the water vapor is not reduced back to water droplets.

る。However, in the former case, a large cooling means is required to uniformly cool and condense a large amount of released steam. In the latter case, a large amount of heat source is required to heat a large amount of water vapor to remove water droplets by heating the water vapor, resulting in a large energy loss. Furthermore, these devices are large in shape because they process a large amount of gas, and cause inconveniences such as an increase in the size of incineration facilities and an increase in construction costs.

構成されている。The air-cooled smoke exhaust cooler 30 is composed of a vertically arranged drum 31 in which an air passage 32 is formed which is connected to the downstream side of the cooling blower 18 and flows upward from below. . A smoke pipe 33 forming a part of the flue 15 is installed in the air passage 32, and heat exchange is performed between smoke exhaust passing through the smoke pipe 33 and air passing outside the smoke pipe 33. Will be The smoke tube 33 is modeled as a polygonal line in the figure, but is actually configured by bundling a large number of relatively thin smoke tubes with some intervals.

C. in the water vapor at about 2 ° C.
The air at 50 ° C. merges and they are rapidly and uniformly mixed in the steam passage 19. As a result, the temperature of the gas mixture of steam and air rises to around 180 ° C,
All the water droplets contained in the water vapor evaporate and change into gas. That is, the steam passage 19 forms a heat exchange means, and uses the heat of the air discharged from the air passage 32 for heating the steam. The water vapor that has been heated by the heat exchange means and has lost water droplets is rapidly cooled to room temperature when released into the atmosphere from the exhaust chimney 50. However, since the water vapor does not contain water droplets that condense again, it becomes white smoke. Will not be visible.

The steam discharged from the water jacket of the equipment constituting the device absorbs the heat of the air that has cooled the exhaust gas from the incinerator 11,
Since the water droplets contained therein are vaporized and then released into the atmosphere, there is no generation of white smoke due to the water droplets contained in the water vapor, and the water vapor discharged from the chimney is not mistaken for the flue gas. In addition, since the heat of the flue gas released to the atmosphere is used for heating the steam, the energy is effectively used. According to the invention of claim 2, the water jackets 13, 2
Since the steam flowing through the steam passage 19 connected to the air passage 2 and the high-temperature air introduced from the air passage 32 merge with each other, the heat exchange between the two can be performed efficiently and the structure of the heat exchange means can be simplified.
