Description

[Detailed Description of the Invention] This invention relates to a lattice-shaped packing body used in gas-liquid contact operation of a chemical reaction device.

Generally, gas-liquid contact operation of chemical reactors, e.g.
Various types of packing bodies are also used in lime gypsum flue gas desulfurization equipment to increase the efficiency of gas-liquid contact. Conventionally, as a packing body for such a gas-liquid contact device, an injection molded product made of synthetic resin as shown in FIG. 1 has been used. That is, it is constructed in a lattice shape by a plate group 11a made up of a plurality of vertical plates 11 arranged parallel to each other and another plate group 12a made up of mutually parallel plates 12 whose side surfaces of these plates 11 are orthogonal to each other. A filling body made of

Since such a packing for a gas-liquid contact device removes contaminants from the air stream by contacting the gas and liquid, the contact time between the gas and liquid is important, and the liquid does not reach the side of the plate. The longer the retention time, the better. However, in the conventional product, since the side surfaces of the plates 11 and 12 constituting the grid are vertically formed, the liquid flows down the side surfaces of the plates 11 and 12 in an extremely short period of time. The liquid contact efficiency was never satisfactory.

In the conventional structure, in order to increase the liquid contact efficiency, it was necessary to increase the number of packing bodies, which led to problems such as increased cost and increased size of the device.

In addition, since the lattice-shaped packing bodies shown in Figure 1 are stacked in multiple tiers with their orientations changed 90 degrees from each other, liquid accumulates at the contact areas where the lattice intersects between the upper and lower tiers, resulting in scale formation. The problem was that it was easy to do.

This idea was made in view of the current situation, and it increases the holding time of the liquid on the side surfaces of the plates that make up the grid to improve the efficiency of contact with the gas, and also allows the liquid to flow down without stagnation, reducing the scale. It is an object of the present invention to provide a packing body for a gas-liquid contact device that can prevent generation.

For this reason, the configuration of this invention is formed by a plate group consisting of a plurality of vertical plates arranged parallel to each other and a plate group consisting of a plurality of parallel horizontal plates perpendicular to the plate group.
When the plates constituting at least one of the above board groups are tilted in the same direction by a certain angle and stacked with the orientation changed by 180 degrees, the lower surface of the upper tilted plate will be the same as the lower one. It is constructed so that it is located almost directly above the top surface of the inclined plate, and the intersections of the vertical plate and horizontal plate near the four corners are provided with recesses or recesses so that the upper and lower ends fit into each other to prevent displacement when stacked. It is characterized by the provision of pillars with protrusions formed thereon.

This invention will be described in detail below based on illustrated embodiments.

FIG. 2 shows a packing body for a gas-liquid contact device according to this invention, and the packing body 20 for a gas-liquid contact device consists of a group of vertical plates 21a and a group of horizontal plates 22a forming a lattice.

The vertical plate group 21a includes a plurality of strip-shaped vertical plates 21 parallel to each other, and the vertical plates 21 are inclined in the same direction at the same angle. On the other hand, the horizontal plate group 22a is formed by arranging a plurality of strip-shaped horizontal plates 22 that are orthogonal to the vertical plate 21 and parallel to each other.

Cylindrical supports 23 and 24 are provided at the intersections of the vertical plates 21 and the horizontal plates 22 near the four corners of the filling body 20 to prevent displacement when stacked on top of each other. The struts 23 and 24 have the same height as the vertical plate 21, and are arranged symmetrically in the horizontal plate direction. Recesses 25 are formed on the upper and lower surfaces of the strut 23, and protrusions 26 that fit into the recesses 25 are provided on the upper and lower surfaces of the strut 24, respectively.

Further, although the vertical plate 21 and the horizontal plate 22 are on the same top surface, the lower surface of the horizontal plate 22 is recessed in from the lower surface of the vertical plate 21, and is configured in a floating state.

Next, the usage state of the filling body 20 according to the above configuration will be explained.

FIG. 7 is a partial cross-sectional side view of a state in which the filling bodies 20 are stacked in three stages, in which the second stage of filling bodies 20b is stacked on top of the first stage of filling bodies 20a with the direction changed by 180 degrees, and the pillars 23 The protrusion 26 of the support column 24 is inserted into the recess 25 of the
is inserted and fixed, and then the third stage filling body 2 is inserted and fixed.
0c is stacked and fixed in a direction 180 degrees different from that of the filling body 20b, that is, in the same direction as the filling body 20a.

As is clear from the drawings, when stacked as described above, the lower surface of the upper inclined vertical plate 21 overlaps the upper surface of the lower inclined vertical plate 21, forming a continuous waveform. Therefore, the liquid that has flowed down along the surface of the upper vertical plate 21 flows down the vertical plate 2 of the lower packed body.
It is received at the upper end of the vertical plate and continuously flows down the surface of the vertical plate.

In the conventional structure, the strip-shaped plates are vertical, and when stacking, the direction is changed by 90 degrees so that the vertical plates intersect at right angles, so the liquid stays on the sides for a short time, and the liquid drips at the bottom of the plates. The drop continues to fall, and moreover, it jumps over one level and hits the top of the filler two levels below, where it is caught.

In the packing body according to this invention, the vertical plate 21 is inclined at a certain angle, so compared to the vertical plane of the conventional packing body, the distance is longer by the amount of the inclination, and furthermore, since it is an inclined surface. The liquid flows down slowly and stays on the sides for a correspondingly longer time.

Note that the number of the pillars is not limited to the embodiment, and may be supported at five or six points depending on the size of the filling body, etc., and the method of fitting the pillars may also be determined on the lower surfaces of the pillars 23 and 24. A configuration may also be adopted in which a recess 25 is formed in each and a protrusion 26 is provided protruding from the upper surface.

In addition, in the embodiment, the lower end of the horizontal plate 22 is connected to the vertical plate 21.
It has a structure that is recessed from the lower end, but it may be made to have the same height as the upper surface. Furthermore, not only the vertical plate 21 but also the horizontal plate 22 may be inclined, or only one of them may be inclined, and the angle of inclination may be determined depending on conditions such as the height of the plate, liquid quality, liquid volume, etc. good.

On the other hand, the heights of the columns 23 and 24 may be such that both or one of the upper and lower ends of the columns protrude beyond the vertical plate 21.

The vertical plate group 21a and the horizontal plate group 22a are integrally combined and can be integrally formed by injection molding, for example.

As explained above, in this invention, at least one of the plate group consisting of a plurality of parallel plates arranged on one side and the plate group consisting of a plurality of parallel plates perpendicular to this plate group is constructed. Since the plates are tilted at a certain angle in the same direction, the distance over which the liquid flows is increased by the slope, and the slope slows down the flow rate, which lengthens the contact time between the liquid and the gas.

Furthermore, since the liquid can flow down the side surface of the plate continuously, the efficiency of gas-liquid contact can be improved and scale generated due to stagnation can be prevented.
