Pyrolyzed coal finisher, coal upgrade plant, and method for manufacturing deactivated pyrolyzed coal

Abstract

To provide a pyrolyzed coal finisher capable of deactivating pyrolyzed coal within a short time without causing a cost increase. A pyrolyzed coal finisher includes: a mixer 86 that forms slurry by mixing particulate pyrolyzed coal that is pyrolyzed coal into a chemical solution having an oxygen blocking function after being solidified; and a belt filter device 88 that filters the slurry formed in the mixer 86 in a state in which each particle of the pyrolyzed coal is coated with the chemical solution. The pyrolyzed coal finisher further includes a chemical solution circulation path 94 that guides the chemical solution separated from the pyrolyzed coal by the belt filter device 88 to the mixer 86.

What is claimed is: 
     
         1 . A pyrolyzed coal finisher comprising:
 a mixer for forming slurry by mixing particulate pyrolyzed coal that is pyrolyzed coal into a chemical solution having an oxygen blocking function after being solidified; and   a filter for filtering the slurry formed in the mixer in a state in which each particle of the pyrolyzed coal is coated with the chemical solution.   
     
     
         2 . The pyrolyzed coal finisher according to  claim 1 , further comprising a chemical solution circulation path for guiding the chemical solution separated from the pyrolyzed coal by the filter to the mixer. 
     
     
         3 . The pyrolyzed coal finisher according to  claim 1 , wherein the filter is a belt filter. 
     
     
         4 . A coal upgrade plant comprising:
 a pyrolyzer for pyrolyzing coal; and   a pyrolyzed coal finisher according to  claim 1  that deactivates the pyrolyzed coal pyrolyzed by the pyrolyzer.   
     
     
         5 . A method for manufacturing deactivated pyrolyzed coal comprising:
 a mixing step of forming slurry by mixing particles of pyrolyzed coal that is pyrolyzed coal into a chemical solution having an oxygen blocking function after being solidified; and   a filtering step of filtering the slurry formed in the mixing step in a state in which each particle of the pyrolyzed coal is coated with the chemical solution.
