Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply apparatus for a gas-liquid contact tower, which is capable of uniformly distributing circulating water on a filler unit in which a large number of filler plates are arranged in parallel at a predetermined interval.

[0002]

2. Description of the Related Art Generally, a gas-liquid contact tower of this type has a packing material unit having a large number of packing material plates arranged side by side in a tower body, and a water spray tank having a bottom plate having numerous water spray holes provided above the packing material unit. A water inlet box is provided on the bottom plate of the sprinkler tank, and the circulating water sprinkled from the sprinkler tank flows down along the surface of the filler plate. A water supply device is provided to which the water supply pipe is connected.

[0003]

By the way, in the case of the water supply device for the gas-liquid contact tower, when the circulating water flows into the water inlet box from the water supply pipe, it is provided on the bottom plate of the sprinkler tank depending on the amount of water. Circulating water was sometimes not evenly sprayed from the spray holes. In particular, when the amount of water is small, the circulating liquid is not evenly dispersed on the bottom plate of the sprinkler tank, which may reduce the gas-liquid contact efficiency. The present invention has solved the above problems, and regardless of the amount of circulating water, it is possible to improve the gas-liquid contact efficiency by uniformly distributing the circulating water on the filler unit. A water supply device is provided.

DISCLOSURE OF THE INVENTION The present invention relates to a gas-liquid contact tower in which a filler unit is arranged in the tower body and a water sprinkling tank having a number of water sprinkling holes in the bottom plate is arranged above the filling material unit.
A water inlet box is arranged on the bottom plate of the water sprinkling tank, and a perforated plate having innumerable water sprinkling holes is provided in the water inlet box at a predetermined distance from the bottom plate, and an upper surface or a lower surface of the perforated plate. It is characterized in that a slide plate having innumerable water spray holes is slidably provided in contact therewith, and a lower end opening of a water supply pipe is inserted and connected to an upper part of a water inlet box. Then, a flow meter is connected to the water supply pipe, and the degree of overlap between the water spray holes of the plate and the water holes of the slide plate is adjusted according to the amount of circulating water passing through the flow meter. .

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of an essential part showing an embodiment of the present invention, FIG. 2 is a schematic perspective view of the essential part showing a developed state, and FIG.
FIG. 1 is a plan view of an essential part showing an overlapping state of the perforated plates, wherein reference numeral 1 is a filler unit, 2 is a sprinkler tank, 3 is a water inlet box, 4 is a water supply pipe, 5 is a flow meter, and 6 is It is a drive motor.

A water sprinkling tank 2 is arranged above the tower body, and a packing material unit 1 in which a large number of packing material plates having uneven surfaces are hung vertically in parallel at a predetermined space below the water spray tank 2. ing. The bottom plate 21 of the sprinkler tank 2 has numerous sprinkler holes 211.
Is provided and the circulating water is evenly sprayed from the water spray holes 211 onto the filler unit 1. Then, when the circulating water sprayed from the water spray holes 211 flows down along the uneven surface of the filler plate, it comes into contact with the air flowing in from the air intake provided on the side of the tower body and is cooled by the latent heat of vaporization. It is designed to fall.

A water inlet box 3 is arranged on a bottom plate 21 of the water sprinkling tank 2, and a perforated plate 31 having an innumerable water sprinkling holes 3a in the water inlet box 3 at a predetermined distance from the bottom plate 21.
Is provided. Further, a slide eye plate 32 having a myriad of water spray holes 3b is slidably provided in contact with the lower surface or the upper surface of the eye plate 31. That is, as shown in the development view in FIG. 2, the collar 3 protruding from the side end of the slide plate 32 is provided.
One end of the threaded rod 61 penetrates through the thread 22, and is screwed into the nut 62. The other end of the threaded rod 61 is connected to the drive motor 6.

Therefore, when the drive motor 6 is operated, the screw rod 61 moves back and forth, and the slide plate 32 moves while contacting the plate 31. Then, as shown in FIG.
Sprinkle hole 3a of the plate 31 and water hole 3b of the slide plate 32
The overlapping degree of is changed so that the amount of circulating water passing through the water spray holes 3a and 3b can be adjusted.

On the other hand, the lower end opening of the water supply pipe 4 is inserted and connected to the upper part of the water inlet box 3, and the water supply pipe 4 is provided with a flow meter 5 for measuring the amount of circulating water passing therethrough. ing. The flow meter 5 is connected to the drive motor 6 via the control device 7, and the water spray holes 3a of the eye plate 31 and the water spray holes of the slide eye plate 32 are described above according to the amount of circulating water flowing in the water supply pipe 4. The degree of overlap with 3b is automatically set. That is, when the amount of circulating water is small, the water spray holes 3
When the opening areas of a and 3b are small and the amount of circulating water is large, the opening areas of the water spray holes 3a and 3b are automatically set to be large. As a result, the water level of the circulating water that has flowed into the water inlet box 3 is maintained constant, and the circulating water that has passed through the sprinkling holes 3a and 3b is evenly dispersed on the bottom plate 21 of the sprinkling tank 2, and then innumerable It is evenly distributed on the filler unit 1 through the holes 211.

[0010]

As described above in detail, the present invention provides a perforated plate having a myriad of water spray holes in the water inlet box and a slide perforated plate having a myriad of water spray holes in contact with the upper surface or the lower surface of the water pan. Since it is slidably provided so that the opening area of the water spray holes can be adjusted, the circulating water can be uniformly sprayed onto the filler unit regardless of the amount of the circulating water flowing into the water inlet box. Therefore, the gas-liquid contact effect can be significantly improved as compared with the conventional device.
