Title: Ikuhisa Hamada: Innovator in Fluid Mixing and Exhaust Gas Treatment

Introduction

Ikuhisa Hamada is a notable inventor based in Kure, Japan, recognized for his contributions to fluid mixing technology and exhaust gas treatment systems. With a total of seven patents to his name, Hamada has made significant advancements in engineering that address critical environmental challenges.

Latest Patents

Hamada's latest patents include a fluid mixing apparatus designed to enhance the efficiency of fluid interactions. This apparatus features a cylinder-shaped flow passage where a first fluid flows through an internal cylinder, which is smaller in diameter than the flow passage. A swirl-generating stator with four vanes is fixed radially within the internal cylinder, creating a dynamic mixing environment. The design incorporates a header space for supplying a second fluid, which interacts with flow separation areas formed along the downstream surfaces of the stator, allowing for effective mixing.

Another significant patent is his engine exhaust gas treatment system, which aims to efficiently reduce and remove nitrogen oxides (NOx) using urea as a reducing agent. This system introduces exhaust gas into a denitration catalyst reactor, where NOx is reduced in the presence of the catalyst. The innovative design includes a diversion means that channels part of the exhaust gas into a urea solution injection evaporator, generating ammonia that is mixed with the exhaust gas for effective treatment.
