【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、可動ロストル式などの都市ゴミ焼却炉にお
いて発生する残渣の溶融処理法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for melting residue generated in a municipal garbage incinerator such as a movable rooster type.
従来、溶融炉における燃焼排ガスによる飛散を抑制す
るために都市ゴミ焼却残渣を成形するに、水をバインダ
ーとして利用し、バインダーに要する経費を節減してい
た。Conventionally, water has been used as a binder to form municipal garbage incineration residues in order to suppress scattering due to combustion exhaust gas in a melting furnace, and the cost required for the binder has been reduced.
しかし、水は粘着性が無いために、都市ゴミ焼却残渣
に対して20〜30重量％程度の水を添加しなければなら
ず、溶融処理において蒸発潜熱ロスが多くなると共に溶
融速度が低下して、補助燃料の消費量が増大し、燃料経
費高騰のため溶融処理経費が高くなる欠点があった。However, since water has no tackiness, about 20 to 30% by weight of water must be added to the incineration residue of municipal garbage, and the latent heat loss in the melting process increases and the melting rate decreases. However, there is a disadvantage that the consumption of the auxiliary fuel is increased and the cost of the melting process is increased due to the soaring fuel cost.
本発明の目的は、都市ゴミ焼却残渣の溶融処理法経費
を大巾に節減できるようにする点にある。SUMMARY OF THE INVENTION It is an object of the present invention to significantly reduce the cost of a melting process for municipal waste incineration residues.

次の通りである。The characteristic means of the present invention is that a dewatered cake of water treatment sludge is mixed with a dried municipal waste incineration residue, the water content of the mixture is adjusted to 10 to 20% by weight, and the mixture is subjected to a molding treatment. Is supplied to a high-temperature hearth made of a carbon-based combustible material to be heated and melted, and its operation and effects are as follows.

高温炉床で、燃焼排ガスによる飛散を十分に抑制した状
態で溶融する。The dewatered cake of water treatment sludge has a water content of 75-80%,
When it is kneaded, it becomes similar to water and is more sticky than water, making effective use of it as a binder, effectively forming the incineration residue of municipal garbage with a dewatered cake of water-treated sludge, and forming the mixture. Is melted in a high-temperature hearth of a carbon-based combustible material such as coke in a state where scattering by combustion exhaust gas is sufficiently suppressed.

前述従来技術よりも大巾に減少して、炭素系可燃物質の
消費量を十分に節減できる。In other words, municipal garbage incineration residues are melted in a molded state using water treatment sludge, which is essentially waste, so municipal garbage incineration residues are scattered by combustion exhaust gas with the melting process,
It is possible to avoid the inconvenience of causing troubles in the melting furnace due to clinker adhesion, etc., and also to significantly reduce the water content of the molding mixture as compared with the above-mentioned prior art, thereby sufficiently reducing the consumption of carbon-based combustible substances. .
さらに説明すると、粘着性の無い水をバインダーにす

分に節減でき、溶融処理経費を安価にできる。To further explain, in the above-described conventional technology using non-sticky water as a binder, 20 to 30
About 10% by weight of water had to be added, but if sticky water treatment sludge was used as a binder, the water content of the mixture of municipal waste incineration residue and sludge was 10% by weight or more, preferably 10 to 20% by weight. Thus, the consumption of the carbon-based combustible material can be sufficiently reduced and the melting processing cost can be reduced by a large decrease in the latent heat loss of evaporation and an increase in the melting rate.
その結果、都市ゴミ焼却残渣の溶融処理を、クリンカ
付着などによる溶融炉のトラブルが無い状態で実行でき

性において一段と優れた都市ゴミ焼却残渣の溶融処理法
を確立できた。As a result, not only can the melting process of municipal waste incineration residue be performed without any trouble in the melting furnace due to clinker adhesion, etc., but also the cost of melting treatment can be sufficiently reduced. The melt processing method could be established.
