Accordingly, it relates to a pyrolysis semi-carbonization apparatus using waste heat that can further improve the semi-carbonization efficiency.

In general, organic sludge generated by biological treatment of food waste and sewage contains a relatively large amount of moisture, and therefore, it is difficult to dispose of it, so it is a well-known fact that disposal is a problem of a large social and environmental level.

Conventionally, the sludge is separated from water using a centrifugal separator or a concentrator, and then disposed of through an appropriate process.

However, in the case of disposing of food waste and sludge from which moisture has been removed, serious pollution of the ocean and pollution of the environment occurs.

Moreover, since 2012, dumping at sea has been banned, and while the treatment method of sludge, such as sludge and animal manure generated by the supply of food waste and sewage, has emerged as a major problem, there is no adequate treatment method for this.

For this reason, various methods that can be recycled as valuable resources using sludge are being sought, and the reduction of sludge to green farmland by cone posts and the molten slug of sludge incineration ash are used as construction materials such as civil works, or as fuel for thermal power plants. A way to replace it is being sought.

However, wastes have various moisture content, and when the moisture content is low, drying and incineration are possible. However, in the case of wastes with high moisture content, there is a problem in that the waste cannot be incinerated because it cannot be dried to be incinerated.

In order to solve this problem, the number of drying rooms, driving means, and burners should be further increased, and unnecessary volume, installation space, and cost are reduced as a drying room, driving means, and burners are basically equipped to treat wastes with high moisture content for commercialization. There is an increasing problem.
