System for conveying biomass
View Patent ↗A system is described for processing biomass through a pyrolysis chamber that utilizes revolving polygon platforms, a conveyor system, and an airlock for introducing or removing biomass into the pyrolysis chamber. Biomass can be introduced via a first revolving polygon platform, and biochar resulting from pyrolysis can be removed via a second revolving polygon platform.
1. A system, comprising:
means for conveying biomass through a pyrolysis chamber, the conveying means comprising drying means, pyrolysis means and means for removing pyrolysis gas and biochar, whereby biomass is introduced via a first revolving polygon platform and biochar resulting from pyrolysis is removed via a second revolving polygon platform;
means for transferring biomass from the first revolving polygon platform onto the means for conveying, the means for conveying comprising a conveyor having the pyrolysis chamber and a means for transferring biochar from the conveyor to the second revolving polygon platform.
2. The system of claim 1 , wherein biomass is transferred at atmospheric pressure into the pyrolysis chamber at a negative or positive pressure relative to atmospheric pressure.
3. The system of claim 1 , wherein biomass is placed as thin sheets on pallets.
4. The system of claim 1 , wherein a polygon of the polygon platform comprises N sides, where N is a number from 3 to 1000.
5. The system of claim 1 , wherein the revolving polygon platforms are synchronized to process material in a semi-continuous manner.
6. The system of claim 2 , wherein positive pressure is attained via the presence of an inert gas.
7. The system of claim 6 , wherein the inert gas is at least one of: carbon dioxide, argon, nitrogen, helium.
8. The system of claim 1 , further comprising a compartment in the conveyor including a plurality of stations for drying biomass.
9. The system of claim 1 , further comprising a compartment in the conveyor including a plurality of stations which pyrolyze biomass.
10. The system of claim 1 , further comprising a compartment in the conveyor a plurality of stations which produce synthesis gas.
11. The system of claim 1 , further comprising a compartment in the conveyor including a plurality of stations which remove residual gases.
12. The system of claim 1 , further comprising a series of compartments in the conveyor including a plurality of stations which cool the biomass.
13. The system of claim 1 , further comprising a series of compartments in the conveyor which sequentially dry the biomass, pyrolyze the biomass, remove volatile gases, and cool the biomass.
14. The system of claim 1 , wherein the system is adapted to fit within a mobile trailer.
15. A system for pyrolysis and gasification of biomass, comprising:
means for conveying biomass through a pyrolysis chamber, whereby biomass is introduced via a first revolving polygon platform, and biochar and volatile components resulting from the pyrolysis are removed via a second revolving polygon platform;
means for transferring biomass from the first revolving polygon platform onto the means for conveying, the means for conveying comprising a conveyor containing the pyrolysis chamber and a means for transferring biochar from the conveyor to the second revolving polygon platform; and
means for transferring biomass at atmospheric pressure onto the pyrolysis chamber at a negative or positive pressure relative to atmospheric pressure via a sliding gate airlock system.
16. The system of claim 15 , wherein the pyrolysis is performed using ramps of temperature and pressure shocks.
17. The system of claim 15 , wherein biomass is placed as thin sheets on pallets, which are moved on a rail system.
18. The system of claim 16 , wherein the pressure shocks are administered via metallic anvils.
19. The system of claim 15 , wherein the revolving polygon platforms are synchronized to process material in a semi-continuous manner.
