It is a dryer for 0 to 20%, even if the dryer is a direct heating type,
Indirect heating type may be used. The dehydrated sludge and the dehydrated residue may be mixed while being dried using one dryer, or may be separately dried by a dryer and then mixed by a mixer after drying.
The dry mixture of sludge and residue is supplied to the crusher 2 and crushed. As a heat source for the dryer, hot gas is generated by the direct fire furnace 4 and can be used as the heat source. In this case, the temperature of the hot gas is 650 ° C. or higher, preferably 750 ° C. or higher. Then, the exhaust gas from the dryer is treated by a dust collector, for example, a cyclone 5, and the powder of the dried mixture collected by the dust is pulverized with the pulverizer 2 together with the dry mixture discharged from the dryer.
The gas is deodorized by being burned in the deodorizing furnace 7 through the heat exchanger 6 and is discharged to the atmosphere by a fan after cooling.
This heat exchanger exchanges heat between the high temperature deodorized gas discharged from the deodorizing furnace 7 and the low temperature gas discharged from the cyclone, and is for improving the efficiency of the deodorizing furnace.

し、大気に放出する。The crusher 2 is only required to be capable of crushing the dry mixture into a shape suitable for molding, and it is not necessary to use a special crusher. For example, as an example of a typical crusher, a claw-shaped rotor in which pins (impact claws) are radially mounted for two to three revolutions is rotated so as to mesh with a claw-shaped stator mounted in a lid. It is possible to use a rotary pin mill having a mechanism of crushing and crushing. A magnetic separator may be provided in front of the crusher in order to remove iron pieces that may be mixed in the residue. Further, in order to prevent the supply hopper to the crusher from being blocked by the fiber content in the residue, an electromagnetic vibrator such as a vibrator may be attached to the hopper and vibrated. It is desirable that the crushed product is crushed so that the residue contained in the crushed product has a shape of 50 mm or less, preferably 30 mm or less. Dust of fine particles generated during the pulverization is collected by a dust collector, for example, a cyclone 8, and is supplied to the molding machine 3 together with the pulverized material discharged from the pulverizer. Further, the exhaust gas from the cyclone 8 is supplied to the deodorizing furnace 7 via the heat exchanger 6, and is burned together with the dry exhaust gas from the dryer 1 to deodorize and is released to the atmosphere.

うに調整してもよい。The molding machine 3 is not limited to a special molding machine as long as it can mold the pulverized material into a shape suitable for the fuel. For example, in order to extrude the air contained in the crushed material in advance and increase the density of the crushed material, it is compressed by a taper screw and supplied to a high pressure roll, and a briquette forming machine for manufacturing briquettes or two It is possible to use an extrusion molding machine or the like that compresses with a screw, extrudes from a nozzle, and cuts the extruded product into a suitable length.
The molded product is the heat of compression generated during compression molding, and the vinyl pieces contained in the residue melt and act as a binder between the sludge particles in the pulverized product, while at the same time forming a film on the surface of the molded product. And acts to contain odors. If the compression heat is insufficient, an electric heater may be attached to the casing of the molding machine, the liner in the casing, the mold plate, the nozzle, etc. to heat. A moisture controller may be provided in the preceding stage of the molding machine to adjust the moisture content of the pulverized product supplied to the molding machine so as to be optimum for molding.
