PURPOSE: A garbage recycling system is provided which recycles garbage as industrial product and utilizes combustible waste disused as an energy source required in the recycling process, and which is very environmentally friendly by properly treating leachate and noxious gas generated. CONSTITUTION: The garbage recycling system comprises a process (a) of selectively collecting and transporting garbage in waste; a process (b) of storing and dehydrating the garbage in storage tank having dehydration function; a process (c) of sorting inorganic materials, that is, incombustible metal scrap, glass or bottle pieces from the stored and dehydrated garbage on moving table; a process (d) of continuously drying and carbonizing the sorted garbage in continuous or batch type rotary furnace using dry distilled gas generated by performing a process (h) of dry distilling combustible waste as a heating source; a process (e) of pulverizing the dry distilled garbage in powder shape; a process (f) of mixing the pulverized garbage with subsidiary raw materials including combustion supporting agent, Activa, clay, limestone and binder; a process (g) of molding the mixed half finished product into a product shape; a process (l) of firing the molded half finished product at a proper low or high temperature to manufacture a finished product, wherein a dry distilled gas generated in the dry distillation process (h) is used as a heating source in the drying and carbonizing process (d), residue generated in the dry distillation process (h) passes through a process (i) of sorting charcoal and inorganic materials such as iron scrap and residue so that the charcoal is injected into a pulverizing process (e) while the inorganic materials are consigned to be treated, and exhaust gas generated in the drying and carbonizing process (d) is completely burnt again as it is being used as a heating source of the firing process (l) so that the completely burnt exhaust gas passes through gas cooling process (l) and air pollution preventing process (m) for removing harmful pollutants before being emitted into the air. |
