Organic waste decomposition system and method with water recycling

Abstract

A system and a method of decomposing organic waste are provided. The system decomposes organic waste in a decomposition chamber without use of enzymes, additives, or microorganisms. In one embodiment, the system decomposes organic waste within 24 hours and deodorizes the odor of decomposing organic waste during decomposition process. The system provides sufficient heat and operating conditions to evaporate moisture from the organic waste without burning the organic waste. The byproduct of the organic waste after decomposition process by the system is substantially homogeneous material that is reduced in volume compared to the organic waste. In one embodiment, the system reuses or recycles water and heat used in the system for different processes in the system. The system includes a blower that provides flow of the moisture inside the system.

1 . An organic waste decomposition system comprising:
 a decomposition chamber configured to decompose organic waste therein such that the decomposition chamber heats the organic waste to release moisture therefrom and continue to heat the moisture and organic waste to decompose, whereby steam is generated in the decomposition chamber;   a condenser in fluid communication with the decomposition chamber via a conduit and configured to precipitate water from the steam passing therethrough;   a blower in fluid communication with the decomposition chamber and the condenser, the blower being configured to flow steam from the decomposition chamber to the condenser; and   a water circuit in fluid communication between the condenser and the decomposition chamber, the water circuit configured to supply precipitated water to the decomposition chamber.   
     
     
         2 . The system of  claim 1 , further comprising:
 a filter between the decomposition chamber and the condenser, the filter being configured to screen debris from the decomposition chamber; and   a flusher configured to flush debris deposited on the filter.   
     
     
         3 . The system of  claim 2 , wherein the flusher is in fluid communication with the water circuit and configured to use the at least part of the precipitated water for flushing. 
     
     
         4 . The system of  claim 1 , wherein the water circuit comprises a water tank configured to at least temporarily store precipitated water therein. 
     
     
         5 . The system of  claim 4 , wherein the water circuit comprises a water pump configured to flow precipitated water from the water tank toward the decomposition chamber. 
     
     
         6 . The system of  claim 1 , wherein the water circuit comprises a water filter configured to filter at least part of the precipitated water that is discharged from the system. 
     
     
         7 . The system of  claim 6 , wherein the water filter comprises an activated carbon filter. 
     
     
         8 . The system of  claim 1 , wherein the water circuit is configured to supply precipitated water to the decomposition chamber when the organic waste is in shortage of moisture for decomposing. 
     
     
         9 . A method of operating an organic waste decomposition system of  claim 1 , the method comprising:
 decomposing organic waste in a decomposition chamber such that the decomposition chamber heats the organic waste to release moisture therefrom and continue to heat the moisture and organic waste to decompose, whereby steam is generated in the decomposition chamber;   condensing the steam passing through a condenser in fluid communication with the decomposition chamber via a conduit to precipitate water;   flowing steam from the decomposition chamber to the condenser with a blower in fluid communication with the decomposition chamber and the condenser; and   supplying precipitated water to the decomposition chamber by a water circuit in fluid communication between the condenser and the decomposition chamber.   
     
     
         10 . The method of  claim 9 , further comprising:
 filtering by screening debris from the decomposition chamber with a filter between the decomposition chamber and the condenser; and   flushing debris deposited on the filter with a flusher.   
     
     
         11 . The method of  claim 10 , wherein the flusher is in fluid communication with the water circuit and configured to use the at least part of the precipitated water for flushing. 
     
     
         12 . The method of  claim 9 , wherein the water circuit comprises a water tank configured to at least temporarily store precipitated water therein. 
     
     
         13 . The method of  claim 12 , wherein the water circuit comprises a water pump configured to flow precipitated water from the water tank toward the decomposition chamber. 
     
     
         14 . The method of  claim 9 , wherein the water circuit comprises a water filter configured to filter at least part of the precipitated water that is discharged from the system.
