Abstract
A method for quickly converting organic waste into energy, including the following steps of S1, performing anaerobic fermentation on organic waste to convert macromolecular organic matter in the organic waste into soluble small molecular organic matter to obtain fermentation liquid; S2, performing solid-liquid separation on the fermentation liquid to obtain a solid-phase part and a liquid-phase part, respectively; and S3, disposing or reusing the solid-phase part as residues, and enabling the liquid-phase part to enter a flow-catalyzed fuel cell to convert organic matter in the liquid-phase part into electrical energy. The present application can quickly and efficiently convert the organic waste into electrical energy.
Claims8
A method for quickly converting organic waste into energy, comprising the following steps:
- S1. performing anaerobic fermentation on organic waste containing lipids to convert lipid components in the organic waste into soluble small molecular organic matter to obtain fermentation liquid, wherein the small molecular organic matter comprises short-chain fatty acids and glycerol;
- S2. performing solid-liquid separation on the fermentation liquid to obtain a solid-phase part and a liquid-phase part, respectively;
- and
- S3. disposing or reusing the solid-phase part as residues, and enabling the liquid-phase part to enter a flow-catalyzed fuel cell to convert the small molecular organic matter in the liquid-phase part into electrical energy;
- wherein the flow-catalyzed fuel cell uses a proton exchange membrane to separate an anode and a cathode, ananolyte uses phosphomolybdic acid as catalysts, and air or pure oxygen is used as a cathode oxidant;
- and after the liquid-phase part enters the flow-catalyzed fuel cell, the flow-catalyzed fuel cell operates at 80-95° C. to convert the small molecular organic matter in the liquid-phase part into electrical energy.
