Abstract: A method for purifying a fluid such as an exhaust gas and waste water, which comprises providing one or more of static mixers on the flow path of the fluid, and mixing and reacting the fluid with a depurative such as ozone in the static mixer to purify the fluid. The method for purifying a fluid allows the purification of a fluid such as an exhaust gas and waste water with significantly good efficiency, and also allows the simplification of an apparatus for use in the purification and the markedly reduction of the cost required for the purification.

Abstract: A fluid mixing-jetting apparatus includes an apparatus body provided at its upstream end with an inlet arrangement for introducing plural kinds of fluids into a flow passage formed in the apparatus body. The apparatus further includes an end plate closing a downstream end of the flow passage of the apparatus body. The end plate is formed with at least one jet opening at a position offset from a center axis of the flow passage of the apparatus body. The end plate may be further formed with a plurality of concave portions on an upstream surface thereof so that the upstream surface of the end plate is formed as a non-planar surface. The jet opening may be non-circular and continuous with an inner circumference of the apparatus body defining the flow passage.

Abstract: There is provided a new bubble floating type separator applicable to a waste water regeneration system which can purify a relatively small amount of waste water by a simple and small-scaled apparatus. The bubble floating type separator comprises a liquid passage for delivering a liquid which contains suspended solids, and an injection pipe, connected to said liquid passage, for injecting a gas selected from air, oxygen gas and ozone gas. A gas-liquid mixer is connected to the liquid passage at a downstream portion of the injection pipe, and a cyclone type bubble separator is connected to a downstream portion of an outlet of the gas-liquid mixer. The cyclone type bubble separator has a discharge port, at a central upper portion, for discharging bubbles floating along with the suspended solids, a cyclone body, and a liquid discharge port at a lower circumferential portion of the cyclone body for discharging a processed liquid so that the suspended solids are removed together with the bubbles.

Abstract: There is provided a new static mixer with a low pressure loss and a high agitating/mixing efficiency. The mixer comprises in the midst of a fluid passage a mixing body having a larger diameter than the fluid passage. The mixing body has a mixing body cylinder portion, an inlet hollow portion having an inlet port fitted to the cylinder portion, and a outlet hollow portion having an outlet port. An impingement cylinder having an diameter larger than a diameter of the outlet port is disposed within the mixing body such that its opening is positioned in a confronting relation with the inlet port. A plurality of recesses are provided at at least one of an inner side portion of bottom of the impingement cylinder, an inner surface portion of the hollow inlet port, an inner surface portion of the hollow outlet port, an inner circumferential portion of a cylindrical portion of the impingement cylinder, and an inner circumferential surface portion of the cylindrical portion of the mixing body.

Abstract: There is provided a mixer for continuously mixing fluids together.The mixer comprises a hollow cylindrical body having an enlarged diameter central portion and inlet and outlet ports at the opposite ends of the body; an impinging disc vertically disposed in the enlarged diameter central portion within the body and having a peripheral projection which defines an annular clearance between the outer surface of the projection and the inner surface of the enlarged diameter central portion of the body.
