Fluid storage tank with plurality of partition plates
A fluid storage tank according to an embodiment of the present invention comprises: a first outer wall section that forms a front face in the length direction, the width direction and the height direction so as to form a space portion in which a fluid is stored; a plurality of partition plates arranged along the length direction of the first outer wall portion to divide the space portion into the plurality of sub-space portions; and an end portion located between the outermost partition plate of the plurality of partition plates and the first outer wall portion, wherein each of the partition plates is formed with a fluid through hole comprising: a gas through hole located on the top of the partition plate; and a liquid through hole located on the bottom of the partition plate so that fluids between the sub-pace portions are in communication with each other.
1. A fluid storage tank comprising:
a first casing wall forming all outer sides of the fluid storage tank in length, width, and height directions, the first casing wall forming a cavity therein to store fluid;
a plurality of partition plates arranged in the length direction of the first casing wall to divide the cavity into a plurality of sub-cavities; and
end units disposed between the first casing wall and outermost partition plates of the plurality of partition plates,
wherein fluid passage holes are formed in the plurality of partition plates to allow the fluid to flow between the plurality of sub-cavities, and the fluid passage holes comprise gas passage holes in upper regions of the plurality of partition plates and liquid passage holes in lower regions of the plurality of partition plates,
wherein bracket units are disposed between the plurality of partition plates adjacent to each other,
wherein openings are formed in the bracket units,
wherein each of the bracket units comprises:
height bracket parts arranged between the plurality of partition plates in the height direction; and
width bracket parts arranged between the plurality of partition plates in the width direction,
wherein the plurality of partition plates extend inwardly from inner wall surfaces of the first casing wall in the width and height directions, connect the inner wall surfaces of the first casing wall to each other, and divide the cavity of the first casing wall into the plurality of sub-cavities,
and wherein each of the plurality of partition plates comprises a solid center, and the gas and liquid passage holes are located at a peripheral area with respect to the solid center.
2. The fluid storage tank of claim 1 , wherein the liquid passage holes are larger than the gas passage holes.
3. The fluid storage tank of claim 1 , wherein the end units comprise reinforcing plate parts arranged to divide spaces between the first casing wall and the outermost partition plates into end spaces.
4. The fluid storage tank of claim 3 , wherein the reinforcing plate parts divide the spaces between the first casing wall and the outermost partition plates in the height direction or the width direction.
5. The fluid storage tank of claim 3 , wherein the fluid flows between the end spaces formed by the reinforcing plate parts through the fluid passage holes formed in the outermost partition plates.
6. The fluid storage tank of claim 5 , wherein the number of the fluid passage holes formed in the outermost partition plates corresponds to the number of the end spaces formed by the reinforcing plate parts.
7. The fluid storage tank of claim 1 , wherein the openings have an arch shape on both ends thereof.
8. The fluid storage tank of claim 1 , wherein the bracket units comprise:
first bracket units disposed between the outermost partition plates and partition plates closest to the outermost partition plates; and
second bracket units disposed between partition plates other than the outermost partition plates,
wherein the first and second bracket units have different shapes.
9. The fluid storage tank of claim 8 , wherein the first bracket units are opened toward the outermost partition plates.
10. The fluid storage tank of claim 8 , wherein flanges are perpendicularly connected to the first bracket units.
11. The fluid storage tank of claim 1 , further comprising a second casing wall enclosing the first casing wall.
12. The fluid storage tank of claim 11 , further comprising stiffeners inserted through the second casing wall with ends of the stiffeners being exposed.
13. The fluid storage tank of claim 12 , wherein other ends of the stiffeners are spaced apart from the first casing wall.
14. The fluid storage tank of claim 1 , wherein the first casing wall has a size larger in the length direction than in the width or height direction.
15. The fluid storage tank of claim 1 , wherein the end units are respectively disposed on both lateral inner wall surfaces of the first casing wall.
16. The fluid storage tank of claim 1 , wherein edges or corners of the first casing wall are rounded or angled.
17. The fluid storage tank of claim 1 , wherein tubes or manhole covers are arranged on the first casing wall.
18. The fluid storage tank of claim 1 , wherein the plurality of partition plates are arranged at different intervals.
