る。[Detailed description of the invention] This invention aims to reduce the amount of water contained in the exhaust gas after heat recovery when water sprinkler equipment is used as a heat recovery means in a heat exchange device that recovers heat from high-temperature exhaust gas generated in a combustion furnace, etc. Moisture is removed in order to eliminate harmful effects such as condensation in the exhaust pipe such as the chimney of the heat exchange treatment pipe and being blown away by the airflow inside the cylinder, causing water droplets to scatter around the area, as well as dust adhering to the inner surface of the exhaust pipe. This relates to a device for preventing condensation of water, in which the discharge side of a blower 2 connected to an exhaust gas pipe 1 is connected to a heat exchange processing tube in which a heat recovery device 4 consisting of a heat recovery tube 7 and a water spray equipment 10 is installed. 3 to recover the retained heat of the exhaust gas sent into the processing cylinder 3, the exhaust gas is released from the exhaust pipe 5 connected to the upper part of the processing cylinder 3, and a part of the discharged air from the blower 2 is released. branch out,
It is characterized in that it is configured to be guided to the base of the exhaust pipe 5 through a conduit 6 and blown into the pipe 5.

加温させるように構成した。 The heat recovery device 4 circulates a fluid to be heated (generally water) in a heat recovery pipe 7 that snakes inside the processing cylinder 3, and a water tank 8 formed at the bottom of the processing cylinder 3.
Water with a temperature higher than that of the fluid to be heated inside is sprayed from the water sprinkling pipe of the water sprinkling equipment 10 by the pump 9, and the heat retained in the exhaust gas sent into the processing tube 3 by the blower 2 is exchanged with the water spray, and the water is sprayed. The heat recovery pipe 7 is heated by the heat recovery pipe 7 and the exhaust gas to heat the internal heated fluid.

る。 When water sprinkler equipment is used as a heat recovery means in this way, the exhaust gas that has undergone heat recovery through heat exchange is almost saturated with water, and therefore water droplets due to condensation of water vapor tend to adhere to the inner wall surface of the exhaust stack 5. . In the present invention, when exhaust gas whose retained heat is recovered by the heat recovery device 4 while passing upward through the processing tube 3 and reaches a low temperature and a high relative humidity reaches the exhaust tube 5, Since a portion of the high temperature exhaust gas branched from the exhaust gas at the base is mixed with this, the difference between the dry bulb temperature and the dew point temperature of the mixed gas increases, thereby preventing water vapor from condensing within the exhaust stack 5.

所期の目的を達し得た効果を有する。 According to the present invention, a water sprinkling equipment is used as a heat recovery means, and the water spray always uniformly wets the heat recovery pipe 7, and its cleaning action prevents the adhesion of dust, etc. in the exhaust gas, thereby preventing the dust from accumulating. Furthermore, water spraying has the advantage of being heated by heat exchange with the exhaust gas, and uses that heat to heat the heat recovery pipe 7 along with the exhaust gas. Part of the exhaust pipe 5
By supplying air to the base of the exhaust gas, water vapor in the exhaust gas that reaches a saturated state due to water sprinkling and reaches the exhaust stack 5 is prevented from condensing in the exhaust stack, and the calorific value of the part of the branched exhaust gas is used for heat exchange. Even after subtracting the amount of heat that is not used, the overall heat recovery efficiency is high.In order to remove the moisture in the exhaust gas passing through the processing tube 3, it is possible to omit the equipment such as a heating coil that reheats the exhaust gas. By branching out and using a portion, it is possible to achieve the desired objective economically.
