  • Publication number: 20230302689
    Abstract: One object is to efficiently secure good quality oil by preventing the clogging of tar in a device body or piping. There is provided a waste plastic liquefaction device comprising a pyrolysis tank that thermally decomposes and gasifies a waste plastics; a gas cooler that cools a pyrolysis gas generated in the pyrolysis tank to produce a generated oil; and a circulation tank that recovers the generated oil produced by the gas cooler and circulates a portion of the generated oil to the gas cooler. The circulation tank has a temperature adjustment device which maintains the temperature of the generated oil in the circulation tank within a predetermined temperature range in the circulation tank. The circulation tank is connected to a centrifugal separator so that the generated oil in the circulation tank is returned to the circulation tank after impurities is removed by the centrifugal separator.

  • Publication number: 20230149991
    Abstract: The purpose of the invention is to reduce various costs including a device manufacturing cost, an energy cost and a running cost by omitting a drying step of a product produced by hydrolyzing a waste with steam, a pellet molding step, and a treatment step for exhaust gas generated by combustion of pellets. A waste biogasification treatment device for subjecting a raw material containing organic waste to hydrolysis treatment and biogasification comprises a hydrolysis device and a biogasification and recovering device for biogasifying the product produced by hydrolysis treatment and recovering generated biogas. The hydrolysis device comprises a treatment vessel having a raw material charging port and a product discharging port; a stirring means provided inside the treatment vessel and stirring the raw material; a steam supply pipe for supplying steam to the treatment vessel; and a steam exhaust pipe for discharging steam from the treatment vessel.

  • Patent number: 11065656
    Abstract: The present invention relates to a method and apparatus for producing a product by hydrolyzing a raw material containing vegetable waste comprising, a hydrolysis treatment step of subjecting the raw material to a hydrolysis treatment with steam by a hydrolysis treatment apparatus, a washing step of washing the hydrolyzed raw material with a washing liquid by a cleaning apparatus, and a solid-liquid separation step of separating the washed raw material into a solid component and a liquid component by a solid-liquid separation apparatus, wherein at least one of the solid content or the liquid con-tent is used as the product.

  • Patent number: 9004464
    Abstract: A curved spring includes one and another end parts configured to approach and separate relative to each other in an approaching/separating direction and plural beam parts that bend between the one end part and the other end part and extend in an extending direction. The plural beam parts are arranged in a width direction orthogonal to the approaching/separating direction. At least one combination of adjacent beam parts among combinations of the plural beam parts includes an outer side beam part having a width greater than a width of an inner side beam part in the width direction. The outer side beam part has a length less than a length of the inner side beam part in the approaching/separating direction. The one and the other end parts and at least one beam part of the plural beam parts are integrally molded on a shared plane by a synthetic resin.
