改善が必要とされていた。When using a fluidized bed incinerator to incinerate waste, depending on the nature of the waste, it is necessary to extract the fluidized medium out of the furnace at a certain rate, adjust the height of the fluidized bed, and clean the medium. Sometimes. As shown in FIG. 1, in the conventional overflow pipe, the amount of medium extracted is adjusted by adjusting the gap between the overflow plug and the overflow plate 2. Also, depending on the medium, it may become swollen due to the adhesion of ash in the waste, resulting in a gap between the overflow plug and the plate.
have been forced to install. When the equipment starts operating under the above-mentioned conditions, the flowing medium (sand, etc.) is blown onto the overflow plug 1 and overflow plate 2 by the purge from the compressed air pipe 7, thereby reducing wear on both. It was remarkable. Especially when the overflow plate 2 is worn out, the overflow pipe 5
The plate welded to the inner wall of the pipe must be completely removed before a new plate can be installed, making work extremely difficult and requiring frequent replacement, so structural improvements are needed. was.

管を提供するにある。Similarly, the cone at the tip of the overflow plug 1 has become rounded due to wear, making it impossible to adjust the clearance with the plate.The system, including the adjustment handle 9, must be replaced, and improvements are needed. It was. The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, insert an insertion tube into the overflow tube, attach an overflow plate to the tip, and provide an easy-to-replace structure for the overflow plug, in case of damage. By changing the material of the overflow plug and overflow plate from conventional SUS to ceramic, we aim to improve wear resistance and provide an overflow pipe that can extend its life. It is in.

出し用溢流管、である。The present invention provides a fluidized bed type incineration system in which the amount of media to be extracted is adjusted by adjusting the gap between the overflow plug 1 and the overflow plate 2 during the fluidized media extraction operation during operation in order to adjust the bed height of the media and to clean the media. In the overflow pipe of the furnace, a plug-in pipe 3 is inserted into the overflow pipe 5 of the secondary kettle, and an overflow plate 2 is installed at the tip of the plug-in pipe 3, {2 } The tip cone of the overflow plug 1 is made of ceramic and has a structure that facilitates replacement, and the overflow plate 2 is made of ceramic and attached to the tip of the insertion tube 3 to facilitate replacement. 1. An overflow pipe for extracting a fluid medium, characterized in that it includes a horizontal groove.

In addition, the cone at the tip is made of ceramic and can be easily installed and removed.

定運転が可能となる。The plug-in tube 3 is inserted into a conventional overflow tube 5. At the tip of the insertion tube, insert the overflow plate 2 (the shaded area indicates ceramic) with the bolt 4 as shown in Fig. 4.
Connect with. Further, the overflow plug 1 has a ceramic tip cone as shown in FIG. 3, and a connecting pipe 10 is provided in the middle. With the above configuration, the unique effect of this embodiment is that by making the tips of the overflow plug and overflow plate 2 made of ceramic, it is possible to eliminate wear caused by air blowing from the compressed air pipe 6. As a result, the amount of medium (sand) extracted can be made constant, so that stable operation of the incinerator is possible.
また溢流プラグ及びプレートともに、取替え容易な構造
としたことで、作業時間の短縮となる。Additionally, both the overflow plug and plate have a structure that is easy to replace, reducing work time.
