Composting system utilizing air recirculation |
摘要 |
An in-vessel composting system wherein the exhaust gas from aerated compost feed material is pretreated by scrubbers and then by a chiller/condenser. A small portion of this cool, relatively dry, ammonia-free gas is passed through an activated carbon column and discharged to the atmosphere. The remaining portion of the exhaust gas is supplemented by ambient air to make-up for the volume of air vented and recirculated through the composting system until such time as the system requires a fresh supply of oxygen. The system is then recharged by blowing in ambient air and venting the spent recirculating air.
