Title: Hitoshi Koyama: Innovator in Fly Ash Carbon Removal
Introduction
Hitoshi Koyama is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of environmental technology, particularly in the removal of unburned carbon from fly ash. With a total of 4 patents to his name, Koyama's work is recognized for its innovative approaches to waste management.
Latest Patents
Koyama's latest patents include an "Apparatus for removing unburned carbon in fly ash" and a "Method for removal of unburned carbon in fly ash." The apparatus efficiently separates unburned carbon based on the properties of fly ash. It consists of a slurry preparation tank where water is added to fly ash to create a slurry. A scavenger addition device is used to introduce a scavenger to the slurry, followed by a vertical surface-modification device that imparts shear force to help the scavenger adhere to the unburned carbon. The process continues with a regulating tank that adds a blowing agent, and finally, a flotation machine separates the unburned carbon from the slurry. The method aims to achieve stable and economically advantageous removal of unburned carbon by mixing fly ash, water, and a trapping agent in a hybrid mixer, applying shearing force, and performing flotation separation.
