本発明は、燃焼炉（微粉炭焚ボイラー、都市ゴミ焼却炉
等をいう）の底部に設けられているボトム水封槽内の液
の濃縮を防止する方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method for concentrating liquid in a bottom water seal tank provided at the bottom of a combustion furnace (pulverized coal-fired boiler, municipal waste incinerator, etc.). Regarding how to prevent this.
微粉炭焚ボイラー、都市ゴミ焼却炉においては、焼却残
滓は温度が高いため乾式処理は困難であるので、第２図
に示すように、焼却炉１０の底部にボトム水封槽１１を
設置して、この中に高温残滓を投入し水封式のチェンコ
ンベア１２にて槽外に排出する構造となっていた。In pulverized coal-fired boilers and municipal waste incinerators, dry processing is difficult due to the high temperature of incineration residue, so a bottom water-sealing tank 11 is installed at the bottom of the incinerator 10, as shown in The structure was such that high-temperature residue was put into this tank and discharged to the outside of the tank by a water ring type chain conveyor 12.
そして、上記焼却残滓の大きさは、微粉炭焚ボイラーに
おいては石炭の産地によって異なり、都市ゴミ焼却炉に
おいては不燃物の種−類によって異なり、大はジュース
罐、瓶のかけらから小は極めて小さい微粉状アッシュが
ある。The size of the above-mentioned incineration residue varies depending on the production area of the coal in pulverized coal-fired boilers, and varies depending on the type of incombustible material in municipal garbage incinerators. There is fine powder ash.
また、上記ボトム水封槽１１には高温残滓だけではなく

合もある。In addition, not only the high-temperature residue but also dust collected by an electrostatic precipitator that captures fly ash generated from the incinerator may be introduced into the bottom water sealing tank 11 by the vibrator 13.
従って、ボトム水封槽内に投入される物は種々雑多とな
って、水槽の底に沈澱するものは上記チェンコンベア１
２によって槽外に排出されるが、細かい粉塵、灰等は水
中に浮遊する。Therefore, various things are thrown into the bottom water sealing tank, and the things that settle at the bottom of the tank are transferred to the chain conveyor 1.
2, it is discharged outside the tank, but fine dust, ash, etc. are suspended in the water.
このため、時間の経過と共に浮遊物の量が増加して、ボ

チェンコンベア１２では槽外への排出が困難となってボ
トム水封槽１１の水替えが必要となる。For this reason, the amount of suspended matter increases over time, and the liquid in the bottom water seal tank is filled with suspended matter. The combustion residue is alkalized and becomes sludge-like, and the input combustion residue no longer settles, making it difficult for the chain conveyor 12 to discharge it to the outside of the tank, making it necessary to change the water in the bottom water sealing tank 11.
本発明はこのような事情に鑑みてなされたもので、ボト

物によって濃縮されることがない。The method for preventing liquid concentration in a bottom water seal tank of a combustion furnace according to the present invention includes a pump that pumps up water containing suspended matter, and a solid content that separates solids from the water containing suspended matter that is pumped up by the pump. Since it is configured with a liquid separator, suspended matter is removed from the liquid in the bottom water seal tank, and the removed water is again put into the bottom water seal tank, making the entire tank circulate. Therefore, the water in the bottom water seal tank will not be concentrated by suspended matter.
続いて、添付した図面を参照しつつ、本発明を具体化し
た一実施例につき説明し、本発明の理解に供する。Next, an embodiment embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

６によって槽外に排出するようになっている。A pump 19 connected to a liquid cyclone 18, which is an example of a solid-liquid separator, is connected to the bottom water seal tank 15.
is provided to guide water in the bottom water seal tank 15 into the liquid cyclone 18. The solid content discharge part 20 at the bottom of the hydrocyclone 18 is located at the top of the inclined part 17, and the solid content to be discharged is removed from the chain conveyor 1.
6, the water is discharged outside the tank.
従って、図示しない燃焼炉から供給される燃焼残滓は、
下部のボトム水封槽１５内に投入され、重い燃焼残滓は

状にならないことになる。On the other hand, light substances such as ash or fine particles become floating substances and do not settle, increasing the concentration of the liquid. However, the water mixed with the floating substances is pumped up by the pump 19 and supplied to the liquid cyclone 18. Solids such as suspended matter separated by specific gravity in the liquid cyclone 18 are discharged from the lower part, dropped onto the inclined part 17, and discharged to the outside by the chain conveyor 16. On the other hand, the separated water is put into the bottom water sealing tank 15 to dilute the water containing floating matter inside, so that the water in the bottom water sealing tank does not become sludge-like.

浮遊物を外部に排出できることとなった。In Fig. 1, 10a indicates an incinerator (including a boiler, a municipal waste incinerator, etc.), and 13a indicates a pipe for sending dust collected by an electrostatic precipitator. As is clear from the above explanation, the method for preventing liquid shrinkage in the bottom water sealing tank is that a solid-liquid separator is installed to separate floating matter from the water in the bottom water sealing tank. It was not ejected,
Floating substances can now be discharged to the outside.
