  • Patent number: 10406475
    Abstract: A honeycomb rotor recovering and concentrating apparatus recovers a gas such as carbon dioxide from flue gases and the like and may be capable of utilizing low-temperature waste heat 100° C. or less. The proposed method involves sorbing carbon dioxide while vaporizing and cooling by contacting a water-insoluble carbon dioxide sorbing material (solid amines, etc.) having an acidic gas sorptive capacity with a mixed gas containing carbon dioxide in a wet state. Warm water is brought into contact with the water-insoluble carbon dioxide sorbing material sorbed with carbon dioxide to desorb high concentration of carbon dioxide. The warm water is separated from the water-insoluble carbon dioxide sorbent material desorbed from carbon dioxide. Then the apparatus is returned from the separation step to the sorption step. Thereby, it is possible to drastically increase the recovery rate and recovery concentration of acidic gas (carbon dioxide) continuously.

  • Patent number: 10386583
    Abstract: When a second housing 80 and a first housing 30 are approached to each other along an axial direction, a body portion 62 of a second fixing member 60 begins to enter in an opening 81 of the second housing 80. Since a vertical wall surface 81a and a cylindrical surface 81b are formed on the opening 81 to substantially match the outer shape of the rear end of the body portion 62, when the second housing 80 is inserted to the first housing 30 while keeping the relative angle until the second housing 80 abuts on a first fixing member 40 which closes the opening and rotating the second housing 80 with respect to the first housing 30 by 90°, a protrusion 64 faces and enters a recessed engagement portion 83 formed on the vertical wall surface 81a. Thus, the protrusion 64 and the recessed engagement portion 83 are fitted and fixed.

  • Patent number: 10350808
    Abstract: Provided is a production apparatus capable of producing a flexible tube whose hardness is naturally varied along the length direction thereof. This mixing valve includes: a first valve configured to distribute a first resin to a resin supply path and a resin discharge path; and a second valve configured to distribute a second resin to the resin supply path and the resin discharge path. In the mixing valve, the mixing proportion between the first resin and the second resin is increased or decreased in association with molding of the flexible tube, by changing a distribution ratio of the first resin in the first valve and a distribution ratio of the second resin in the second valve while keeping constant the total of the supply mounts of the first resin and the second resin supplied to a die.

  • Publication number: 20190193019
    Abstract: An energy-efficient, space-saving, low-cost, waste-heat-utilizing ventilating air conditioning apparatus uses a honeycomb rotor having a function of adsorbing or absorbing contaminants such as carbon dioxide and VOC gas. The honeycomb rotor is disposed in a rotor rotating device having at least a processing zone and a re-generation desorption zone. Air to be processed is passed through the processing zone to remove contaminants such as carbon dioxide to produce supply air. Water is directly sprayed or dropped into a heat exchanger provided at an entrance of the re-generation desorption zone to evaporate the generated water film by heating. The generated saturated steam is introduced for desorbing carbon dioxide and pollutants, and the stream is discharged the stream outdoors. The ventilating air conditioning apparatus can operate without the energy loss associated with ventilation.

  • Publication number: 20190076782
    Abstract: A dry room for gas substitution has a drying chamber to receive dry air from a dry air supply device. Gas is circulated between inside the drying chamber and the dry air supply device. An airtight container is accommodated in the drying chamber. A low dew point gas supply device coupled to the airtight container removes moisture and supplies low dew point gas to the airtight container via a filter that removes foreign matter. An inert gas purification device removes oxygen and supplies an inert gas to the airtight container. A gas exhaust passage exhausts gas in the airtight container to outside of the drying chamber. The low dew point gas supply device and the inert gas purification device are independently provided so that moisture removal via the low dew point gas supply device is adjusted independently of oxygen removal via the inert gas purification device.

  • Publication number: 20190022574
    Abstract: Outside air is cooled and dehumidified by a pre-cooler to pass through an adsorption zone of a carbon dioxide adsorbing rotor, producing air having a low carbon dioxide concentration which is cooled by an intercooler. The air that has passed through the intercooler is passed through an adsorption zone of a moisture adsorption rotor and then supplied to a low humidity working chamber. Return air from the low humidity working chamber may be mixed with the air leaving the pre-cooler. A part of the air which passed through the intercooler is branched to pass through a purge zone of the moisture adsorption rotor before being sent to a regeneration zone of the humidity adsorption rotor. Air that passed through the regeneration zone of the humidity adsorption rotor is mixed with outside air and then passed through a regeneration zone of the carbon dioxide adsorption rotor before being exhausted.
