The processing method for food waste energy circulation zero emissions

摘要

The present invention relates to a method for processing an energy-circulating non-emission food waste, an input step of putting the collected food waste into a storage hopper, and a crushing step of crushing the input food waste at a breaker and then crushing at the crusher. , A primary drying step of drying the crushed food waste in a wet dryer, a secondary drying step of drying the wet-dried dry matter in a dry dryer, and a carbonization step of carbonizing the dry-dried dry matter in a pyrolysis carbonization furnace, and It characterized in that it consists of a stench removal step of burning and removing the odor and wet gas generated in the drying process of the first drying step and the second drying step and the combustion gas generated in the carbonization step of the carbonization step in a stench deodorization furnace. The energy circulation type discharge-free food waste treatment method according to the present invention simplifies the process through the process of drying and carbonizing together, instead of separating and treating intermediate wastes such as contaminants, waste water, and condensate during the treatment of food waste. It has the effect of reducing the cost of equipment and operating costs, and preventing the leakage of odors that may be unintentionally generated in a separate separation process. Waste heat and steam generated during the treatment process are recirculated as energy to dispose of food waste. It has the effect of reducing the external supply energy required for the treatment process.
