Gas-liquid contacting plate, gas-liquid contacting laminated block body, gas-liquid contacting laminated structure and gas purification device
View Patent ↗A gas-liquid contacting plate of the present invention in which a treatment liquid flows from an upper side to a lower side direction of a substrate and a part of gas being in contact with the treatment liquid is absorbed into the treatment liquid, includes a downward protruding saw teeth-shaped portion in which a lower end side of the substrate has pitches at predetermined gaps. Further, a pore group for liquid dispersion having a predetermined gap is provided in a plurality of lines, in the substrate. An arrangement thereof is a zigzag arrangement.
1. A gas-liquid contacting plate made of resin, the gas-liquid contacting plate comprising:
a substrate for allowing a treatment liquid to flow an upper side to a lower side direction thereof and allowing a part of gas in contact with the treatment liquid to be absorbed into the treatment liquid;
a liquid dispersion structure subjected to a hydrophilic treatment on a surface of the substrate, for dispersing the treatment liquid on the gas-liquid contacting plate; and
a liquid delivery structure for making the treatment liquid uniformly flow down from the gas-liquid contacting plate,
wherein the gas-liquid contacting plate includes a liquid receiving structure for bringing the treatment liquid, which flows down from the upper side, into contact with the gas-liquid contacting plate.
2. The gas-liquid contacting plate according to claim 1 , wherein in the liquid delivery structure, a lower end side of the substrate has a downward protruding saw teeth shape having pitches at predetermined gaps, and
wherein the downward protruding saw teeth-shaped portion is formed of bilaterally symmetric inclined surface portions and a flat portion which is a top surface of inclined surface portions.
3. The gas-liquid contacting plate according to claim 1 , wherein the liquid dispersion structure is formed of a plurality of lines of pore groups or protrusion groups at predetermined gaps, and
wherein an arrangement of the pore groups or the protrusion groups is in a zigzag arrangement.
4. The gas-liquid contacting plate according to claim 3 , wherein the liquid receiving structure includes protruding liquid receiving groups arranged at predetermined gaps between the pore groups or the protrusion groups and an upper edge portion of the substrate.
5. The gas-liquid contacting plate according to claim 4 , wherein the liquid receiving group is formed of a plurality of cylinders or columns.
6. The gas-liquid contacting plate according to claim 1 , wherein the surface of the substrate is a hydrophilic rough surface structure.
7. The gas-liquid contacting plate according to claim 1 , wherein the substrate contains a hydrophilic material.
8. A gas-liquid contacting laminated block body, which is a laminated body in which the gas-liquid contacting plate according to claim 1 is laminated in a direction perpendicular to a vertical axis direction.
9. A gas-liquid contacting laminated structure comprising a plurality of lines of the gas-liquid contacting laminated block bodies according to claim 8 which are alternately laminated by a phase of 90 degrees in a vertical axis direction.
10. The gas-liquid contacting laminated structure according to claims 9 , wherein a gap between laminated gas-liquid contacting plates which form the gas-liquid contacting laminated block body is the same as a gap between peak portions of downward protruding saw teeth-shaped portion.
11. A gas purification device, comprising:
a gas purification device main body for circulating a gas;
the gas-liquid contacting laminated structure according to claim 9 which is disposed inside the gas purification device main body;
a gas introduction unit for introducing the gas from either of a bottom portion or upper portion of the gas purification device main body;
a gas discharge unit for discharging the gas from a side different from the gas introduction unit side;
a treatment liquid supply unit for supplying a treatment liquid from an upper side to the gas-liquid contacting laminated structure; and
a treatment liquid discharge unit installed in the vicinity of the bottom portion of the gas purification device main body, for discharging the treatment liquid.
