本発明は、ごみに下水汚泥を混ぜて焼却する混焼装置に
関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a co-incineration device for mixing waste with sewage sludge and incinerating the mixture.
［従来の技術］
近年、下水処理場で発生ずる汚泥量は膨大となり、この
下水汚泥の処理処分が大きな課題となっている。そこで

る。[Prior Art] In recent years, the amount of sludge generated in sewage treatment plants has increased enormously, and the treatment and disposal of this sewage sludge has become a major issue. Therefore, for example, sewage sludge is co-combusted with garbage to make it more efficient from an energy standpoint. This processing is performed from the viewpoint of facility size, operating conditions, location conditions, etc.
ところが、下水汚泥をごみと混焼する場合、ごみと下水
汚泥の混合にムラがあるとそれぞれの燃焼特性から混焼

につれて炉内での安定した燃焼を阻害するようになり、
燃焼実温度の急降下や灰中に生の汚泥が出てしまうとい
う問題があり、混焼が困難である。However, when sewage sludge is co-combusted with garbage, if the mixture of garbage and sewage sludge is uneven, the combustion rate (sewage sludge amount / (waste signature + sewage sludge amount)) increases due to the combustion characteristics of each, and as a result, the begins to interfere with the stable combustion of
Co-combustion is difficult because of the problems of a sudden drop in actual combustion temperature and raw sludge appearing in the ash.

。また、下水汚泥とごみの撹拌を人士に頼っていること
から依然としてそれらの混合ｌ、うが生ｅ易く、燃焼上
支障があった。[Problems to be Solved by the Invention] However, in the cake-placed co-combustion type garbage and sewage sludge co-combustion device described in ``--, when the co-combustion rate of F water sludge is high, the garbage pick +-i In order to thoroughly stir the mud and garbage inside the sewage tank with the crane 102 to minimize uneven mixing, the crane operating rod is required to perform excessive stirring work. In addition, since the mixing of sewage sludge and garbage was dependent on human workers, the mixing of the sewage sludge and garbage was still prone to sludge, which caused combustion problems.
従って、燃焼ト支障がなく高い下水汚泥の混焼率を達成
することが困難であった。Therefore, it has been difficult to achieve a high co-combustion rate of sewage sludge without causing combustion problems.
なお、ド水汚泥を燃焼υ１゛ガスの熱で予備乾燥し２て
から炉内に投入する方法を床用することも考えられるが
、これによれば混合ムラが少なくなるが、反面建設費及
び維持管理費が多大になり好ましくない。It is also possible to use the method of pre-drying the water sludge with the heat of the combustion gas and then putting it into the furnace, but this will reduce the unevenness of mixing, but on the other hand it will increase the construction cost and This is undesirable as it increases maintenance costs.
