Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brackish water separator, and more particularly to a brackish water separator using a corrugated plate suitable for installation in a drum or flash tank.

As shown in FIGS. 1 and 2, a conventional brackish water separation device of this type stacks a large number of corrugated plates 1 at a predetermined distance from each other with distant pieces 2 interposed between them. It is assembled by inserting the rod 3 and fixing its both ends to the corrugated plate 1 by welding or the like. Note that arrow a indicates the direction of steam flow.

However, using such a distant piece 2 to maintain a predetermined distance between each corrugated plate 1 not only increases the number of parts, but also requires a lot of time to assemble, which causes an increase in costs. I was getting used to it.

In addition, in order to enhance the brackish water separation effect of such a brackish water separation device, it is necessary to increase the number of corrugated peaks formed on the corrugated plate 1, or increase the width or number of corrugated plates 1. This increases the size of the brackish water separator, so it is difficult to increase the brackish water separation effect, especially in cases where the volume is small, such as a drum or flash tank, and the space in which the brackish water separator can be installed is limited. It was difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide a brackish water separation device that eliminates the drawbacks of the prior art described above, has a small number of parts, and is easy to assemble.

In order to achieve this object, the present invention integrally forms a spacing protrusion on the corrugated plate to maintain the spacing between each corrugated plate, and furthermore, connects the protrusions and prevents the brackish water mixture from forming the corrugated plate. It is characterized by integrally forming a protrusion extending obliquely with respect to the flow direction.

Embodiments of the present invention will be described in detail below with reference to the drawings.

3 to 6 are views showing one embodiment of the present invention, in which FIG. 3 is a front view of the corrugated plate, FIG. 4 is a side view of the same, FIG. 5 is an enlarged front view of the same main part, and FIG. The figure is an enlarged side view of the same main part.

A plurality of spacing protrusions 4 are formed at intervals on the peaks of the corrugations in the corrugated plates 1A to maintain a predetermined spacing between the corrugated plates 1A, and these protrusions 4 A protrusion 5 is formed in a state that is inclined with respect to the steam flow direction a. These protrusions 4 and protrusions 5 are integrally formed with the corrugated plate 1A by extrusion molding using a press or the like, but in the figure, there are four protrusions 4 and two protrusions 5, and each protrusion 5 is oppositely formed. They are arranged in a figure-eight pattern, slanting in the direction of the direction. Note that 6 is a rod insertion hole.

The corrugated plates 1A thus formed are directly stacked one on top of the other so that both protrusions 5 form a figure-eight shape or an inverted figure-eight shape, and rods are inserted into the rod insertion holes 6 in the same manner as in the past. It is assembled by inserting the corrugated plate 1A through the corrugated plate 1A and fixing its both ends to the corrugated plate 1A by welding or the like.

Therefore, each corrugated plate 1A can be easily assembled without using distant pieces, the number of parts can be reduced, and the assembly work time can be significantly shortened.

Furthermore, when steam flows in the direction of arrow a through the gaps between the corrugated plates 1A, the steam not only changes its flow direction by the corrugations of the corrugated plates 1A, but also collides with each protrusion 5, These also change the flow direction, and by providing each protrusion 5, the contact area of the corrugated plate 1A with the steam increases, so water droplets in the steam can be efficiently separated. As a result, the length in the direction of steam flow can be shortened, making it possible to make the device smaller and lighter.When installed inside a drum or flash tank, the internal space can be expanded. This facilitates inspections during regular inspections that are carried out every few years.

7 and 8 are a front view and a side view of a corrugated plate according to another embodiment of the present invention.

In this embodiment, the corrugated plate 1B is provided with a number of small protrusions 7 whose height is lower than that of the protrusions 4, in addition to the same spacing protrusions 4, protrusions 5, and rod insertion holes 6 as in the previous embodiment. are integrally formed.

Therefore, since the flow direction of steam is also changed by the small protrusion 7, the brackish water separation effect can be further enhanced.

As explained above, according to the present invention, the spacing protrusion for maintaining the spacing between each corrugated plate is integrally formed on the corrugated plate, and the conventionally used distant piece is omitted. By reducing the number of parts and shortening the assembly time, the brackish water separation device can be manufactured at low cost.

In addition, since the corrugated plate is provided with protrusions that are inclined with respect to the flow direction of the brackish water mixture, a contraction channel and a widening channel are formed in the flow path, further changing the flow path, and the corrugated plate The chance of collision of the brackish water mixture with the brackish water mixture and the collision area are increased, and the brackish water separation is performed efficiently.

In addition, by integrally providing protrusions and protrusions on the corrugated plate, the reinforcing effect of the corrugated plate is exhibited, and the corrugated plate does not curve too much and worsen the space factor. A predetermined mechanical strength can be obtained even by using a corrugated plate, and the device can be made more compact and lightweight.
