METHOD TO PROCESS BIRD LIME Russian patent published in 2012 - IPC C10L1/00 C10L3/00 F23G5/27 

FIELD: agriculture.

SUBSTANCE: bird lime is previously dehydrated and dried, heated up to the temperature of its destruction without oxygen access with subsequent separation into carbonaceous residue and steam and gas mixture. The steam and gas mixture is condensed to form a liquid and a non-condensed part of the steam and gas mixture. The non-condensed part is processed into power, which is used for power supply to drives during realisation of the method and to supply electric loads of poultry factories. The liquid part is used as liquid fuel and is separated into two parts. Heat produced from combustion of the first part of liquid fuel is used for power supply to processes of heating up to the destruction temperature and bird lime drying. The second part of the liquid fuel is collected into an accumulating tank, is used as a commercial product or for process and household needs of an enterprise. The carbonaceous residue is used as adsorbent for cleaning of gases that are discharged after bird lime drying and in process of treatment of water that was produced at the stage of preliminary dehydration of bird lime. After saturation of carbonaceous residue it is used as a fertiliser and an additive to improve soil structure.

EFFECT: method makes it possible to reduce costs for execution of bird lime recycling process, to use recycling products in a complex manner and to ensure environmental safety of the recycling process.
