Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mist separation device that efficiently separates fine mist contained in a gas flow. Furthermore, the present invention relates to a mist separation device that can be easily combined with a corrugated collision plate.

(Prior art) As described in, for example, Japanese Utility Model Publication No. 55-18098, the conventional technology is to hold a plurality of corrugated collision plates at a predetermined interval P to form a separating device. A mist separation device was formed by inserting and fixing a corrugated collision plate into a comb-shaped frame.

In such conventional mist separation devices, a separate comb-shaped frame is required to assemble a single corrugated collision plate to form a mist separation device, and therefore, the device requires only the frame. It had the disadvantage of being large.
In addition, the accuracy of the airtight seal between the corrugated collision plate and the frame affects the mist separation efficiency, which requires man-hours and costs to manufacture and assemble the jig, and furthermore, when used in a gas flow containing corrosive mist. However, there was a problem with corrosion of the metal frame.

(Means for solving the problem) This invention was made in order to solve the above problems.A plurality of mist separation chambers are installed in the gas outflow direction on either the front or back side of the corrugated collision plate. Partition walls having protrusions at the tips of the partitions are integrally provided at predetermined intervals, and fitting holes are provided on the back surface of the partition walls into which the protrusions at the tips of the partitions of adjacent corrugated collision plates fit. Hooked protrusions are preferably provided at the tips of at least the partition walls parallel to the gas outflow direction of the plate, and the hooked protrusions of the corrugated collision plate adjacent to the side walls of the partition walls that have the hooked protrusions engage with the hooked protrusions. This is a mist separation device with a mouth.

In addition, it is preferable that the inside of the partition wall is hollow with a continuous fitting hole opening on the back surface, and both the front and back walls are connected by a plurality of spacing pieces.

Further, it is preferable that at least the surface of the corrugated collision plate has an inclined rib that intersects with the gas outflow direction.

(Example) Regarding the drawings below, one aspect of the present invention:
Explain in detail. As shown in Fig. 1A and B, 1 is a corrugated collision plate, and the end face 1 is perpendicular to the gas flow direction shown by the arrow.
It is made of a wide material such as plastic for blocking the entire gas flow path. In the present invention, a large number of narrow partition walls 2 which divide the corrugated collision plate 1 into a plurality of mist separation chambers at approximately equal intervals in the gas outflow direction are integrally provided on the corrugated collision plate 1, and the back surface of the partition walls 2 is provided. A fitting hole 3 is provided in the partition wall 2, and a protrusion 4 that fits into the fitting hole 3 provided on the back surface of the adjacent corrugated collision plate 2 is provided at the tip of the partition wall 2. Both ends of each corrugated collision plate 1 parallel to the gas outflow direction A protrusion with a hook 5 is provided at the tip of the partition wall 2a, 2b protruding from the portion, and the protrusion with hook 5 of the collision plate 1 adjacent to the side wall of the partition wall 2a, 2b having the protrusion with hook 5 engages with the protrusion with hook 5. Hanging entrance 6
By providing the protrusions 4 of the adjacent corrugated collision plates 1, 1 and the fitting holes 3, and engaging the hooked protrusions 5 and the hooked protrusion engaging openings 6,
A plurality of corrugated collision plates 1, 1 are engaged with each other to form a mist separation chamber 7 therebetween, forming a curved gas flow path, and the gas fluid passing through the mist separation chamber 7 collides with the inclined wall surface 1b, This is a mist separation device in which mist in a gas fluid aggregates and separates from a gas layer while passing through a winding passage. Reference numeral 8 denotes inclined ribs (slanted grooves) that intersect with the gas outflow direction and are provided at least on the surface, preferably on both the front and back surfaces, of the inclined wall surface 1b of the corrugated collision plate 1. Providing this rib 8 improves mist separation efficiency and discharge of aggregated mist. This is preferable because it makes it easier.

In the mist separation device of the present invention, the partition wall 2 serves as a spacer to hold the adjacent corrugated collision plates 1, 1 at a constant interval and to divide the mist separation chamber 7 into predetermined sizes. If the interval between the two is too wide, the mist separation efficiency will be reduced, and if the interval is too narrow, the fluid resistance will be large and the flow will be laminar, which will actually reduce the mist separation efficiency. The interval between the partition walls 2 is usually about 70 to 200 mm. In addition to the specific example shown in FIG. 1, the device of the present invention may of course use wave-shaped collision plates as shown in FIGS. . In addition, the second
It goes without saying that the joining of the corrugated collision plates in the structures shown in FIGS. 4 to 4 is exactly the same as that described above.

(Operations and Effects of the Invention) According to the invention, the corrugated collision plate 1 consists of end faces 1a, 1c perpendicular to the gas flow direction, and an inclined surface 1b connecting them, and this single corrugated collision plate is arranged at regular intervals. In order to connect them to form a box-shaped mist separation device, a plurality of partition walls 2 are integrally formed by injection molding or the like at approximately equal intervals in the vertical direction with the corrugated collision plate 1, and the tip of the partition wall 2 of the corrugated collision plate 1 is A projection 4 is provided at the position, and a fitting hole 3 into which the projection 4 of the adjacent corrugated collision plate 1 is fitted is provided on the back surface of the partition wall, and a large number of corrugated collision plates 1 are fitted together to form a mist separation device. The fitting hole 3 and the protrusion 4 serve for positioning when adjacent collision plates are overlapped, and the mist separation device can be easily formed without using welding or welding, so that the number of assembly steps can be reduced.

When the corrugated collision plate is formed from a plastic material, etc., the corrugated collision plate 1, the partition wall 2, the protrusion 4 provided at the tip of the partition wall, and the fitting hole 3 provided on the back surface of the collision plate are formed by injection molding or the like. Since these can be integrally molded, the dimensional accuracy of the assembly of the collision plate can be improved, and the mist separation performance can be stabilized due to the improved dimensional accuracy.

Furthermore, in the present invention, the hooked protrusion 5 and the hooked protrusion engagement opening 6 are provided at least at the tip of the partition wall 2 at both ends and the corresponding side surface of the partition wall and are engaged and fitted, so welding and welding are unnecessary. 1st
As shown in detail in Figure B, the protrusion 4 and the fitting hole 3
Simultaneously with the positioning operation, the hooked protrusion 5 and the hooked protrusion engagement opening 6 are engaged and integrated into one body, which eliminates the need for complicated work such as welding and welding, and has the advantage of reducing assembly man-hours. be.

(Effects of the invention) The present invention has the above-described configuration, and by fitting a single corrugated collision plate together, it can be reliably assembled and fixed with one touch, and furthermore, by engaging the hooks, adjacent corrugated collision plates cannot be detached. Has few advantages.

The corrugated collision plate of the present invention has a great practical effect of stabilizing mist separation performance due to improved assembly dimensional accuracy.
