にくいものである。 In the above configuration, the temperature of the dry exhaust gas flowing inside the powder supply pipe 13 is likely to change depending on the nature of the organic waste, and if it is low, a dew point will occur, and the temperature of the dry exhaust gas flowing inside the powder supply pipe 13 will change. The circulation pipe 19 and the like are subjected to acid dew point corrosion. Therefore, by changing the amount of organic waste to be treated, the temperature of the dry exhaust gas flowing through the powder supply pipe 13 is maintained at a predetermined high temperature, but this makes it impossible to treat organic waste in quantitative quantities. The processing efficiency is poor. In addition, it is difficult to follow changes in processing amount to temperature changes, and it is difficult to maintain the temperature of the dry exhaust gas at a predetermined high temperature.

生じることはない。 Therefore, the present invention provides a method for controlling the temperature of dry exhaust gas that solves these problems, and is characterized by supplying the exhaust gas in the incinerator to the powder supply pipe through the exhaust gas supply pipe. The temperature controller detects the temperature inside the powder supply pipe and adjusts the opening degree of a damper installed in the exhaust gas supply pipe based on the detected value. When the exhaust gas temperature is low, the exhaust gas can be supplied from the incinerator into the powder supply pipe to raise the temperature, which allows the amount of organic waste to be processed to be constant and improves processing efficiency. It is something that can be done. Furthermore, it has a good ability to follow temperature changes, and can always keep the temperature of the dry exhaust gas supplied into the collector at a predetermined high temperature, so that acid dew point corrosion does not occur.

を調整する第２温度コントローラである。 Hereinafter, one embodiment of the present invention will be described based on FIG. 2. Reference numeral 25 is an exhaust gas supply pipe whose one end communicates with the inside of the incinerator 1 and the other end communicates with the inside of the powder supply pipe 13, and a first damper 26 is interposed in the middle. A first temperature controller 27 detects the temperature inside the powder supply pipe 13 and adjusts the opening degree of the first damper 26 based on the detected value.
Reference numeral 8 denotes a second damper interposed at a location downstream of the deodorizing pipe connection point of the circulation pipe 19, and 29 indicates the deodorizing pipe 2.
A third damper 30 is interposed in the powder supply pipe 13, and a second temperature controller 30 detects the temperature inside the powder supply pipe 13 and adjusts the opening degrees of the second and third dampers 28 and 29 based on the detected value. It is.

According to this embodiment, in addition to this configuration, the second temperature controller 30 detects the temperature of the dry exhaust gas flowing inside the powder supply pipe 13, reduces the opening degree of the second damper 28, and The opening degree of the damper 29 can be adjusted appropriately to increase the amount of exhaust gas entering the exhaust gas introduction pipe 11 from the incinerator 1, thereby increasing the amount of exhaust gas introduced into the dryer 10 and raising the temperature. It is.
