Title: Hiroshi Ishizaka: Innovator in Flue-Gas Treatment Technologies
Introduction
Hiroshi Ishizaka is a prominent inventor based in Hiroshima, Japan. He has made significant contributions to the field of environmental technology, particularly in flue-gas treatment methods. With a total of 13 patents to his name, Ishizaka's work focuses on improving the efficiency and effectiveness of pollution control systems.
Latest Patents
One of Ishizaka's latest patents is a wet type flue-gas desulfurization method. This innovative apparatus is designed to treat exhaust gas containing mercury. It includes an upstream absorption tower, an absorbent spray nozzle, and a make-up water supply unit. The system ensures that the chloride ion concentration of the absorbent remains above 50,000 ppm, preventing mercury from being released back into the environment. This technology not only enhances the purity of recovered gypsum but also reduces the usage of industrial water.
Another significant patent is the exhaust gas treating method and apparatus. This invention involves adjusting the exhaust gas temperature at the exit of a heat recovery unit to not exceed the dew point temperature of sulfur trioxide. A heavy metal adsorbent is then introduced into the exhaust gas, effectively removing heavy metals even when high-sulfur coal is used as fuel. This method is crucial for minimizing environmental impact and ensuring compliance with stringent emission regulations.
