<p>In a device for the aeration of composting reservoirs of biomass, each aeration mouth in the biomass being treated is supplied separately and independently from the others by means of a conduit (4) adapted to this effect. All the conduits (4) have an energy drop substantially equal to 5-20 times, preferably 8-12 times more than the energy drop of the air which traverses the biomass. Each conduit (4) is connected to the collector (5) situated outside the reservoir (1) by a closure tap (7) and is provided with a device (9) for injecting in the conduits a high pressure liquid in order to, in case of need, clear the discharge orifices when they are plugged. The conduits (4) and optionally the collector (5) are separated according to the maturity degree of the biomass, in groups having different air volume and pressure. Furthermore, the free end of each conduit (4) which terminates at the bottom (3) of the reservoir (1) acts as an aeration mouth.</p> |
