〔産業上の利用分野〕
本発明は汚泥を焼却するにあたり、熱媒（例えば燃料油
又は蒸気）乾燥機を使用して汚泥を乾燥する際、予じめ
熱媒を加熱する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for incinerating sludge by using a heating medium (for example, fuel oil or steam) when drying the sludge using a dryer. Concerning a method of heating.
従来、乾燥機用熱媒油（又は蒸気）は焼却炉排ガスで直
接加熱していた（例えば、特開昭５９−１４５４１５号
公報）。このため、停電等による緊急停止時熱媒の過加
熱からの熱媒及び熱媒加熱器の保護のため非常用発電機
又は非常用駆動装置を備え、熱媒の循環を維持し続けな
ければならなかった。Conventionally, heat transfer oil (or steam) for dryers has been directly heated with incinerator exhaust gas (for example, Japanese Patent Laid-Open No. 145415/1983). For this reason, in order to protect the heat medium and heat medium heater from overheating during emergency shutdowns due to power outages, etc., an emergency generator or emergency drive device must be provided to continue to maintain the circulation of the heat medium. There wasn't.
そのため、設備費が高価になるとともに、これらの装置
を動かす動力源を別に必要とした。This resulted in high equipment costs and required a separate power source to operate these devices.
本発明は、上記欠点を解消するため、汚泥を予じめ熱媒
を用いて乾燥したのち焼却する方法において、汚泥を焼
却した焼却炉から発生する排ガスを熱源とした空気予熱
器で熱媒加熱用空気を加熱し、この加熱用空気で熱媒加
熱器を介して熱媒を加熱したのち、加熱された熱媒を使
用して汚泥を乾燥することを特徴とする汚泥の焼却方法
を提案する。In order to solve the above-mentioned drawbacks, the present invention provides a method in which sludge is dried in advance using a heating medium and then incinerated, in which the heating medium is heated using an air preheater using exhaust gas generated from the incinerator that incinerates the sludge as a heat source. We propose a method for incinerating sludge, which is characterized by heating air for use, heating a heating medium with this heating air via a heating medium heater, and then drying the sludge using the heated heating medium. .
本発明では、熱媒を加熱用空気により間接的に加熱する
ため、緊急時加熱用空気を大気に放出することにより対
処できるため、非常用電源又は駆動装置を必要としない
。さらに、排ガスの腐食、摩耗等から熱媒加熱器を守る
ことができる。In the present invention, since the heating medium is indirectly heated by the heating air, an emergency power source or a drive device is not required because the emergency situation can be dealt with by discharging the heating air to the atmosphere. Furthermore, the heat medium heater can be protected from corrosion of exhaust gas, abrasion, etc.
なお、本発明において、「汚泥」とは、下水汚泥、し原
汚泥および例えば紙パルプ汚泥、油泥等の工場排出汚泥
を含むものとする。In the present invention, "sludge" includes sewage sludge, raw sludge, and factory discharge sludge such as paper pulp sludge and oil sludge.
以下、本発明方法の一実施例を図面に基づいて説明する
。An embodiment of the method of the present invention will be described below with reference to the drawings.

適する水分に乾燥されたのち焼却炉２で燃焼される。汚
泥を焼却した排ガスは燃焼用空気予熱器３で燃焼用空気
を加熱した後、空気予熱器４で熱媒加熱用空気を加熱す
る。熱媒加熱用空気は空気予熱器用ファン５で空気予熱
器４に押し適寸れ、熱媒加熱器６に送られる。In FIG. 1, sludge and the like are dried in a dryer 1 to a moisture content suitable for incineration, and then burned in an incinerator 2. The exhaust gas from incinerating the sludge is used to heat combustion air in a combustion air preheater 3, and then to heat medium heating air in an air preheater 4. The heat medium heating air is pushed to the air preheater 4 by the air preheater fan 5 to an appropriate size, and is sent to the heat medium heater 6.

使用される。熱媒油（又は蒸気）を加熱した空気は空気
予熱器４に戻るが、一部は燃焼用空気予熱器３に送られ
る。The heat medium oil (or steam) is sent from the heat medium heater 6 to the dryer 1 by the heat medium pump 8, and is returned to the heat medium heater 6 for circulation. The air heated with the heat transfer oil (or steam) returns to the air preheater 4, but a portion is sent to the combustion air preheater 3.
空気予熱器４へは外気空気を一部取り込み空気予熱器４
で再度循環し使用される。燃焼用空気予熱器３で加熱さ

を通過後、焼却炉４で燃焼用空気として使用される。Part of the outside air is taken in to the air preheater 4.
It is then recycled and used again. The air heated by the combustion air preheater 3 is pressurized by the pressure booster 7 and then heated by the combustion air preheater 3.
After passing through, it is used as combustion air in the incinerator 4.
本発明では、熱媒油加熱器熱源に空気予熱器からの加熱
空気を使用することにより、停電時等の緊急時用に必要
だった、熱媒油循環ポンプの非常用動力が不必要になっ
ただけでなく、焼却物性状の変化により、乾燥が不要の
時、熱媒油の冷却に必要だった多量の冷却水を減らし、
空気予熱器からの空気量をコントロールすることにより
可能となった。In the present invention, by using the heated air from the air preheater as the heat source for the heat medium oil heater, the emergency power of the heat medium oil circulation pump, which was required for emergencies such as power outages, is no longer required. In addition, due to changes in the properties of the incinerated material, when drying is not necessary, the large amount of cooling water required to cool the heat transfer oil can be reduced.
This was made possible by controlling the amount of air from the air preheater.
