Title: Misao Igarashi: Innovator in Waste Treatment Technologies
Introduction
Misao Igarashi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of waste treatment technologies, holding a total of 3 patents. His innovative systems focus on improving the efficiency of drying moist sludge and treating waste materials in a molten state.
Latest Patents
One of Igarashi's latest patents is a "System for drying moist sludge." This system includes a drier as its main component, which consists of a lower gas fluidizing section and an upper high-speed fluidizing section. The moist sludge is introduced into a mixer, where each particle is coated before being supplied to the gas fluidizing section. Fine particles are fluidized and dried by heating elements, and the dried sludge particles are collected in a dust collector. The system efficiently recycles gas and manages the flow of dried sludge.
Another significant patent is the "System for treating waste material in a molten state." This improved system treats finely pulverized combustible waste material, including incombustible materials like pulverized coal and dried sludge. The waste is burnt in a primary combustion furnace and then in a secondary combustion furnace, where incombustible materials are melted to form molten slag. This innovative approach allows for high-efficiency combustion and smooth discharge of molten slag from the furnace.
