Filling component for gas-liquid contact and cooling tower using filling component for gas-liquid contact

Abstract

The invention provides a filling component for gas-liquid contact and a cooling tower which can capture all dispersed cooling water with high efficiency; a wetted wall of a liquid membrane with a uniform membrane thickness and a uniform flow speed is formed on the surface of a thin plate for gas-liquid contact which is used to form the filling component for gas-liquid contact so as to realize high heat exchange efficiency, miniaturization, and energy conservation. The filling component for gas-liquid contact is provided with a plurality of thin plates for gas-liquid contact; a wetted wall is formed on the plate surface of the thin plate for gas-liquid contact by cooling water; and the temperature of the cooling water is decreased by the effect of latent heat accompanying the direct contact of the wetted wall and the external airflow. The cooling water capturing part comprises a bending part for cooling water capture which comprises a surface convex part and a back convex part formed in a specified range from the upper end to the lower part of each of the thin plates for gas-liquid contact, and no space running through in the perpendicular direction is provided between the surface convex part and the adjacent back convex part; a concave-convex surface is formed at the lower part of the cooling water capturing part to allow the cooling water to form a wetted wall with a uniform membrane thickness and a uniform flow speed on the surface and the back surface of the thin plate for gas-liquid contact.

Description

technical field [0001] The present invention relates to a cooling tower and a filling member for gas-liquid contact used in the cooling tower. In the cooling tower, a liquid is flowed down along the surface of a plurality of vertically arranged thin plates for gas-liquid contact to form a wetted wall, and the wetted wall and The latent heat effect accompanied by the direct contact of the external air flow reduces the temperature of the liquid by heat exchange. Background technique [0002] Conventionally, there are packing members disclosed in Patent Document 1 to Patent Document 3 as such filling members for gas-liquid contact. In the filling member for gas-liquid contact disclosed in Patent Document 1, the cooling water sprayed by the sprinkler forms a water film on the surface of the thin plate and flows down. As a means of catching cooling water, water droplet catching portions that protrude alternately on the front side and the back side or protrude only on the same su...

AI Technical Summary

Problems solved by technology

[0009] However, in the filling member for gas-liquid contact disclosed in Patent Document 1, since the sprinkling water catcher is partially formed, there is a problem that all the sprinkling water cannot be caught by the sprinkling water catcher.

In addition, there is also the problem that most of the cooling water becomes droplets and falls down in the middle of the filling part

[0010] In addition, the filling member for gas-liquid contact disclosed in Patent Document 2 has the problem of not being able to catch all the sprayed water because the sprayed water receiving portion is partially formed like the filling member for gas-liquid contact disclosed in Patent Document 1.

[0011] In addition, since the filling member for gas-liquid contact disclosed in Patent Document 3 has no vertically penetrating space, all scattered cooling water can be caught. The grooves of the plate become collective flow

Therefore, it is difficult to form a water film on the entire surface of the thin plate, and there is a problem that the thickness and the speed of the water film cannot be made uniform.
