Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fluid contact plate, which can be used in various applications as described below.

(1) For water treatment, such as contact aeration, trickling filters, gravity flow type catalytic oxidation, etc. (2) For gas absorption towers, such as exhaust gas cleaning towers, air purification towers, etc. (3) For static mixers, powder Particle mixers, etc. (4) For heat exchangers, plate heat exchangers, cooling towers, etc. (5) For catalytic catalytic reaction devices, such as catalyst devices for automobile exhaust gas purification, ammonia synthesis reaction devices, etc. Conventional technologies and problems Points: Fluid contact plates conventionally used for various purposes have a cross-sectional area that changes in the direction of flow of the fluid, are insufficient to impart swirling motion to the fluid, have poor power pressure loss efficiency, and are single-cylindrical. In the case of large-capacity fluid processing, it is difficult to increase the size of the device other than by increasing the number of tubes, and there is a problem that the device becomes expensive.

Means for Solving the Problems The fluid contact plate of the present invention has the following configuration as a means for solving the problems of the conventional example.

(1) In a transverse columnar body whose front and rear end faces are either square, rectangular, symmetrical trapezoid, or isosceles triangle, the transverse columnar body is cut by a cutting line that moves parallel from the front end face to the rear end face. The cutting line is made to continuously turn to an angle of 90 degrees or close to 90 degrees along the central axis passing through the center of gravity of both the front and rear end surfaces, and the cut surface formed by bisecting the cutting line is Use a curved plate consisting of a combination of

(2) The cutting line is a straight line, and the curved surface shape obtained when the turning speed is the same or a ratio close to the advancing speed along the central axis is almost a hyperbolic parapet surface.

(3) The cutting line consists of a combination of curved surface shapes of two basic shapes: an L-shape that turns to the left and an R-shape that turns to the right.

(4) A composite basic shape is created by alternately combining four basic shapes L and R, and the curved surface shape of the surface of this composite basic shape is utilized by arranging the composite basic shapes in a staggered manner or in a line.

(5) Utilizing the curved shape of the surface of the basic L-shape and basic R-shape arranged in an appropriate order.

(6) The above-mentioned arrays were arranged in the same manner as described above, and the rows were shifted so that the concave portions and convex portions fit in the vertical direction, and the concave portions and convex portions were stacked to form an aggregate, and this was utilized.

Effects According to the present invention, the fluid always swirls with the same cross-sectional area in the fluid flow direction, which not only increases the effective surface area but also gives the fluid swirling motion. Strong contact with the contact surface increases the effect of contact adsorption, and since the cross-sectional area does not change, pressure loss is small and power pressure loss efficiency is improved.

In addition, in the case of independent cylindrical aggregates, large-capacity ones can be easily manufactured by simply stacking and fixing the contact plates, so many individual cylindrical ones can be installed side by side like conventional static mixers. The equipment is much cheaper compared to
