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.
Claims11
A method for purifying a fluid which comprises, in purifying a fluid, such as an exhaust gas and waste water,
- utilizing a static mixer which is provided with a mixer main body which is arranged on a fluid flow path and is formed in a cylindrical shape having a diameter greater than that of the fluid flow path, the mixer main body comprising a mixer main body cylindrical unit, a hollow inlet disk unit having a hollow part which is positioned at the end of the mixer main body cylindrical unit and serves as an inlet, and a hollow outlet disk unit having a hollow part which is positioned at the other end of the mixer main body cylindrical unit and serves as an outlet, wherein a collision cylinder having a diameter greater Than or equal to that of the inlet of the mixer main body and smaller than the inside diameter of the mixer main body cylindrical unit of the mixer main body is fixedly housed concentrically in the mixer main body so that the side of the opening of the collision cylinder faces to the inlet, a groove is provided on at least one part of the interior face of the mixer main body and the surface of the collision cylinder which have contact with the fluid,
- wherein the groove provided on a plane which has contact with the fluid and faces the flow of the fluid are formed in volute shapes, and the groove provided on a peripheral face which has contact with the fluid and places along the flow of the fluid are formed in spiral shapes,
- arranging on the fluid flow path at least one of the static mixers,
- occurring a mixed reaction between the fluid, such as the exhaust gas and the waste water, and a depurative, such as ozone, and
- purifying The fluid.
A static mixer comprising a mixer main body which is arranged on the fluid flow path and is formed in cylindrical shape having a diameter greater than that of the fluid flow path, the mixer main body comprising a mixer main body cylindrical unit, a hollow inlet disk unit having a hollow part which is positioned at the end of the mixer main body cylindrical unit and serves as an inlet, and a hollow outlet disk unit having a hollow part which is positioned at the other end of the mixer main body cylindrical unit and serves as an outlet,
- wherein a collision cylinder having a diameter greater than or equal to that of the inlet of the mixer main body and smaller than the inside diameter of the mixer main body cylindrical unit is fixedly housed concentrically in the mixer main body so that the side of the opening of the collision cylinder faces to the inlet, and
- a groove is provided on at least one part of the interior face of the mixer main body and the surface of the collision cylinder which have contact with the fluid, wherein the groove provided on a plane which has a contact with the fluid and faces the flow of the fluid is formed in volute shapes, and the groove provided on a peripheral face which has contact with the fluid and places along the flow of the fluid is formed in spiral shapes.
