Patent number: 10087093Abstract: A fluid treatment apparatus for treating a target fluid is provided. The fluid treatment apparatus includes a cylindrical reactor and one or more catalyst members each having a rod-like or plate-like shape extending in a longitudinal direction within the reactor. The cylindrical reactor decomposes an organic substance contained in a mixed fluid of the target fluid with an oxidant by an oxidation reaction under heat and pressure. The cylindrical reactor has an introduction port on one end and a discharge port on the other end. An upstream end surface, relative to a direction of flow of the target fluid, of each of the catalyst members is located in a downstream vicinity of or upstream from an inflow position where the target fluid flows into the reactor through the introduction port. Each of the catalyst members is suspended with the upstream end surface being fixed.Type: GrantFiled: June 4, 2015Date of Patent: October 2, 2018Assignee: Ricoh Company, Ltd.Inventors: Toshiyuki Mutoh, Shogo Suzuki, Yuu Zama, Aya Utsuki, Kimio Aoki, Hideyuki Miyazawa, Makito Nakashima, Kenichi Hayakawa, Shigeru Yamada

Publication number: 20150368129Abstract: A fluid treatment apparatus for treating a target fluid is provided. The fluid treatment apparatus includes a reactor to decompose an organic substance contained in a mixed fluid of the target fluid with an oxidant by an oxidation reaction. The reactor includes a cylindrical base material, a catalyst, and a migration space. The catalyst accelerates the oxidation reaction of the organic substance, and is disposed along an inner periphery of the cylindrical base material. Into the migration space, solids precipitated in the oxidation reaction migrate in a longitudinal direction without accumulating.Type: ApplicationFiled: June 3, 2015Publication date: December 24, 2015Inventors: Yuu ZAMA, Toshiyuki MUTOH, Hideyuki MIYAZAWA, Makito NAKASHIMA, Shogo SUZUKI, Aya UTSUKI, Kenichi HAYAKAWA, Kimio AOKI, Shigeru YAMADA
