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.

Fluid treatment apparatus

A fluid purifying apparatus that purifies fluid containing organic matter has a reactor including a first transfer part that receives the fluid from outside and transfers the fluid in a vertical direction from an upper side to a lower side while heating and pressurizing the fluid and mixing the fluid with an oxidant, a second transfer part that receives the fluid that has passed through the first transfer part and transfers the fluid in the vertical direction from the lower side to the upper side, and a partition member that partitions an upper part of the reactor into the first transfer part and the second transfer part, and a solid storage part that communicates with the first transfer part and the second transfer part below the partition member and receives solid matter contained in the fluid that settles while the fluid is transferred.

Fluid purifying apparatus

A disclosed image removing device includes a roller peeling member onto which a recording material with the image forming substance having thermoplastic properties is superposed; a heating unit configured to heat the image forming substance; a pressurizing unit configured to apply pressure to the roller peeling member and the recording material superposed thereon to cause the image forming substance heated by the heating unit to adhere to the roller peeling member; a separating unit configured to separate the recording material from the roller peeling member after the image forming substance has adhered to the roller peeling member; and a removing unit configured to remove, from the roller peeling member, the image forming substance that has been transferred from the recording material to the roller peeling member. The removing unit is driven in such a manner that the removing unit and the roller peeling member pressurize/contact/slide against each other.

A cleaning method for cleaning a powder container by introducing a cleaning medium into the powder container from a first opening part of the powder container for attaching powder in the powder container to the cleaning medium and discharging the cleaning medium together with the powder from a second opening part situated opposite from the first opening part is disclosed. The method includes a step of releasing the cleaning medium from a position higher than the first opening part of the powder container.
