Description
The present application is a divisional application of the chinese patent application having an application number of 201610388993.3, an application date of 2016, 6 and 3, and an invention name of "gas-liquid contact packing sheet".
Technical Field
The present invention relates to a packing sheet for gas-liquid contact of packing material for a cooling tower.
Background
In the prior art, as shown in fig. 3, a cooling tower 1 includes: a filler 2 formed by arranging a plurality of thin plate-like filler plates 20 for gas-liquid contact in parallel; a water supply tank 4 for supplying treated water from above the filler 2; an exhaust fan 6 for introducing outside air from the side surface of the packing material 2 into the space between the plurality of packing plates 20 for gas-liquid contact of the packing material 2; a water discharge tank 5 into which the treated water cooled by the air passing through the filler 2 flows; and an air sealing material 3 provided at an upper end of the packing material 2, specifically, at a gap between the upper end of the packing material 2 and the water supply tank 4.
Outside air is introduced into the cooling tower 1 from a side surface (a side surface perpendicular to the gas-liquid contact packing plate 20) of the cooling tower 1, and a louver 7 is attached to the side surface to prevent treated water supplied to the packing material 2 from scattering to the outside and to prevent foreign matter from entering the cooling tower 1.
As is known from patent document 1 (japanese patent application laid-open No. 2013-11400), a water supply tank 4 and an axial flow fan 6 as an exhaust fan are provided above a filler 2, and a drain tank 5 is provided below the filler 2.
As is known from patent document 2 (jp 55-31421 a), since the gas-liquid contact packing plate 20 constituting the packing material 2 is used to exchange heat by directly contacting air when the treated water flows down along the surface of the packing plate, the packing plate having a zigzag-shaped overall longitudinal cross section is used to exchange heat efficiently.
By providing the gas-liquid contact packing plate 20 with a zigzag longitudinal cross section and a wave shape as a whole, the flow rate of the treated water can be reduced and the heat exchange efficiency can be improved to some extent.
However, in this case, since the treated water flows down without any resistance of the surface of the gas-liquid contact packing plate 20, in order to improve the heat exchange efficiency, it is necessary to increase the surface area of the gas-liquid contact packing plate 20, for example, to increase the size of the valley ridges of the serrations (that is, to increase the height difference between the valley ridges), but if the surface area of the gas-liquid contact packing plate 20 is increased, although the contact area between the treated water and the air is increased, the resistance of the air flow between the packing plates passing through the packing material is also increased, and if the resistance is increased, the amount of air under the same power is decreased, so that the heat exchange efficiency is lowered, and the cooling capacity is adversely affected. Therefore, there is a limitation in increasing the surface area of the gas-liquid contacting packing plate 20.
Disclosure of Invention
In view of the problems of the conventional gas-liquid contact packing plate constituting the packing material, an object of the present invention is to provide a gas-liquid contact packing plate capable of reducing air resistance without significantly reducing the surface area of the gas-liquid contact packing plate, and increasing the amount of air to improve heat exchange efficiency.

For example, the ridges or valleys of two adjacent rows of undulations are offset from each other by the connecting portion. For example, the connecting portion includes a plurality of upward inclined surfaces and a plurality of downward inclined surfaces. For example, the upward inclined surface of the connecting portion is connected to the upward inclined surface of the adjacent undulating portion, and the downward inclined surface of the connecting portion is connected to the downward inclined surface of the adjacent undulating portion.
