IPC: B01D53/77
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a gas treatment method which is applicable especially to a microbiological treatment using sludge, etc., and is excellent in treating an organic gas by bringing a gas being treated into contact with a gas-treating liquid in a gas treatment tower while changing the ratio of flow rate with time to decompose or remove a gas dissolved in the gas-treating liquid. SOLUTION: A gas containing methanol as an organic gas is treated by using an activated-sludge treating liquid as the gas-treating liquid. A gas 2 being treated comprising air and methanol contained therein is supplied to a treatment tower 5. An electrical variation component is placed on the number of revolutions of an air blow fan 7 to vary the number of revolutions; that is, the amount of the gas treated is varied with time and thus the state of a gas-liquid mixture, wherein the gas and the liquid are in contact with each other while flowing, is brought into an unstationary turbulent state; and the renewal rate of the gas-liquid interface is increased, increasing the absorption rate of the gas being treated by the treating liquid, increasing the reaction rate of the gas with the liquid, and increasing the decomposition ratio of the gas.  Here, the frequency of the variation component is set at 0.1 Hz to 30 kHz, and the ratio of the component is set at 1-100%.

Abstract: PROBLEM TO BE SOLVED: To make weight lighter by previously forming a release layer consisting of a silicon polymer of a fluorine polymer on the surface of a flexible tube for internal pressure packing used at the time of thermal molding in a metal mold and removing the flexible tube from a frame after the molding. SOLUTION: The surface of the flexible tube 30 is provided with the release layer 31 consisting of the silicon polymer and/or fluorine polymer, by which the drawing of the flexible tube from the inside of the frame after the molding is made possible. A tube of high tensile strength in spite of the relatively thin thickness of, for example, a nylon tube, or the like, used thus far is usable for the flexible tube 30 itself. The flexible tube, therefore, elongates along the inside surface of the mold part 21 of the metal mold M without rupturing in spite of the intricate crass-sectional surface shape of the mold part when the internal pressure of the flexible tube is increased by filling a high-pressure fluid into the flexible tube at the time of the molding.  The drawing of the tube from the inside of the frame by the release layer disposed on the surface of the tube after the molding is thus made possible.
