Abstract

The present invention provides a vertical gas distribution device for aerobic compost and a gas distribution method. Current gas distribution pipelines are easily blocked by organic materials, resulting in poor ventilation due to non-uniform local ventilation and cleaning difficulties. The inventive device comprises a compost chamber, a compost bin, a compost heap, a percolate tank, and a plurality of gas distribution branch pipes at the bottom of the compost chamber, the pipes being vertically movable in the chamber; the percolate tank is positioned at the bottom of the chamber and under the pipes; an air inlet is provided on the side wall of the tank, and an outlet is provided on the side wall of the chamber; the compost bin is inside the compost chamber, and the compost heap is in the compost bin; each pipe is top sealed, with a plurality of vent holes on the side wall, and its bottom connected to the tank. The present invention is usable for compost ventilation.
