  • Publication number: 20200010340
    Abstract: There is provided a liquid treatment apparatus which includes a treatment tank which generates a gas phase in a swirling flow of liquid, by swirling an introduced liquid and which treats liquid by applying a pulse voltage to a generated gas phase to generate plasma, in which an insulator which is an insulating space forming member is disposed on a wall surface of one end of the treatment tank so as to prevent a swirling flow from being affected, faces the space connected via the through-hole of the insulator, and thus the first electrode is disposed.

  • Publication number: 20190352199
    Abstract: A liquid processing apparatus includes a processing tank, a first electrode, an insulator, a liquid introduction port, a discharge portion, a second electrode, an opening portion, and a power supply. The first electrode is disposed at the first end of the processing tank. The insulator covers at least a part of a side surface of the first electrode disposed to protrude from an inner wall of the first end of the processing tank into the processing tank. The liquid introduction port causes a liquid to swirl by introducing the liquid in a tangential direction of the processing tank and generates a gas phase in a swirling flow of the liquid. An outer diameter of the insulator is smaller than an outer diameter of a gas-phase generating space where the gas phase is generated in the processing tank.

    Abstract: A tensioner includes a power spring, and a backup member being in contact with the power spring and supporting the power spring by acting an urging force in a direction opposite to a radial shift of the power spring in a direction in which the power spring is wound. The power spring is unwound in a condition in which an inter-plate frictional force of the power spring is small in a case where an urging force acting from a power spring to a tension member is greater than a load acting from the tensioner arm to the power spring and the power spring is wound in a condition in which the inter-plate frictional force of the power spring is large in a case where the urging force acting from the power spring to the tension member is smaller than the load acting from the tension member to the power spring.

  • Publication number: 20190177187
    Abstract: A liquid treatment device that achieves an effective treatment by forcibly contacting a swirl flow of a hydrogen peroxide-containing treated liquid with a liquid to be treated that has been processed to contain copper ions or iron ions includes a rod-like first electrode, a plate-like second electrode formed of a copper- or iron-containing metal, and a first treatment vessel that causes a liquid to swirl and generate a gas phase in a swirl flow of the liquid. A pulse voltage is applied to the generated gas phase to generate a plasma. The second electrode serves as an anode, and reaches inside of a supply section for a liquid to be treated. The liquid to be treated containing the generated copper ions or iron ions is forcibly brought into contact with hydrogen peroxide generated by the plasma. In this way, the Fenton's reaction effectively takes place, and the liquid treatment performance improves.
