Method and apparatus for treating solid wastes

Abstract

Waste burning means, gas treating means in communication with said waste burning means and gas separating means in communication with said gas treating means and waste burning means, said waste burning means includes a burning chamber and pressurized pyrolysis chamber, wherein burning chamber is being made such that it is capable of burning completely organic wastes thereof, whereby gas products of combustion are produced, and said pyrolysis chamber being made such that it is capable of converting plastic wastes into synthesis gases through utilization of heat from the burning chamber, heat exchanging means disposed within the burning chamber being arranged in a manner wherein water from a water source is capable of conversion into steam thereof through utilization of heat in the burning chamber, said gas treating means includes a secondary treatment chamber in communication with the burning chamber, wherein high temperature gas products of combustion coming from the burning chamber is capable of mixing with low temperature steam, said gas separating means being arranged such that the gas products mixed with steam coming from the gas treating means is capable of swirling cyclonic motion thereof, thereby allowing the lighter gases to be discharged to the atmosphere and be separated from particulates and heavier gases which are subsequently recycled and feed back into the burning chamber, and steam and synthesis gas lines provided in the waste burning means being arranged such that it is capable of introduction to the burning chamber the steam produced by the heat exchanging means and synthesis gas coming from the pyrolysis chamber.

1 . A method for treating solid wastes comprising the steps of:
 a) Confining separately biomass wastes from plastic wastes;   b) Burning the biomass wastes;   c) producing steam by heat exchange through utilization of the heat produced by the burning biomass wastes;   d) converting plastic wastes into synthesis gases through utilization of the heat coming from the burning chamber;   e) introducing the said steam and synthesis gases to the flame of the biomass fuel such that there is an increase in temperature, thereby burning the biomass completely and produces high temperature gas products of combustion;   f) treating the high temperature gas products with cold steam such that dioxin and furan formation is eliminated;   g) allowing the treated gas products to undergo swirling cyclonic motion such that particulates and heavy gases are separated from lighter gases, whereby the lighter gases are discharged in the atmosphere and the particulates and heavy gases are recycled and retreated again.   
     
     
         2 . A method for treating solid wastes according to  claim 1  wherein the temperature of the heat is about 1000 to 1500 degree Celsius. 
     
     
         3 . An apparatus for treating solid wastes comprising:
 Waste burning means, gas treating means in communication with said waste burning means and gas separating means in communication with said gas treating means and waste burning means, said waste burning means includes a burning chamber and pressurized pyrolysis chamber, wherein burning chamber is being made such that it is capable of burning completely organic wastes thereof, whereby gas products of combustion are produced, and said pyrolysis chamber being made such that it is capable of converting plastic wastes into synthesis gases through utilization of heat from the burning chamber, heat exchanging means disposed within the burning chamber being arranged in a manner wherein water from a water source is capable of conversion into steam thereof through utilization of heat in the burning chamber, said gas treating means includes a secondary treatment chamber in communication with the burning chamber, wherein high temperature gas products of combustion coming from the burning chamber is capable of mixing with low temperature steam, said gas separating means being arranged such that the gas products mixed with steam coming from the gas treating means is capable of swirling cyclonic motion thereof, thereby allowing the lighter gases to be discharged to the atmosphere and be separated from particulates and heavier gases which are subsequently recycled and feed back into the burning chamber, and steam and synthesis gas lines provided in the waste burning means being arranged such that it is capable of introduction to the burning chamber the steam produced by the heat exchanging means and synthesis gas coming from the pyrolysis chamber.   
     
     
         4 . An apparatus for treating solid wastes according to  claim 3  wherein water storage means and steam storage means are in communication with said heat exchanging means. 
     
     
         5 . An apparatus for treating solid waste according to  claim 3  wherein said gas separating means is a cyclonic separator having a stack for gas discharge and guide means disposed thereof, said guide means being made such that it is capable of providing swirling cyclonic motion to the gases passing thereof, such that the lighter gases are capable of moving upward and be discharged in said stack and the particulates and heavy gases are capable of returning to the burning chamber.
