Description

Low-temperature catalytic carbonizer

The present invention relates to a low-temperature catalytic carbonizer for increasing the thermal efficiency of carbides.

Typically, various treatment systems have been proposed and applied for drying and carbonizing various organic wastes such as livestock waste, sewage and wastewater waste, and food waste. In most cases, organic waste is put into a long rotating pipe and transported. It is done through a drying method using a heat source, which is hot air supplied by a burner, etc.

However, in the above-mentioned treatment method, the organic waste input into the drying furnace is slowly moved through the pipe and dried by continuous supply of hot air from the burner. The moisture content of the organic waste input is about 70-80%, which is 10-20%. In order to drastically reduce the drying process, a significant drying time is required and the resulting energy consumption is large, which is not only inefficient and uneconomical, but also a waste of energy as the heat source emitted is not recycled and is discharged to the outside. There were problems such as severe and causing considerable air pollution.

In addition, this superheated steam that comes out through the carbonization process contains foreign substances such as dust, tar, and water vapor, so if it is just released into the atmosphere, air pollution will be severe and the drying process and carbonization process cannot be carried out as a circulation process, so the efficiency is significantly reduced. There were problems such as:
