る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing suspended matter in the sea, and more particularly, to a cooling water intake port of a thermal or nuclear power plant or other plant. The present invention relates to a device for isolating floating substances in the sea, such as jellyfish and garbage, from the intake and excluding them from entering the intake.

所の運転が不能になることがある。Conventionally, seawater has been used as cooling water when condensing steam for power generation.However, jellyfish sometimes develops abnormally in the sea, and the jellyfish is sucked together with the seawater from the cooling water intake and filtered. And the amount of cooling water decreases, and the operation of the power plant may become impossible.

は、非常に困難であるという問題点がある。However, in the first means, the flow rate of the hot wastewater is increased to discharge the water from a water outlet below the sea surface, and the cooling water flows from the lower intake port at a low flow velocity, which causes a large amount of jellyfish. In that case, although it is a micro flow rate,
It cannot be expected to prevent the jellyfish from being sucked into the intake. In the second means, a jellyfish inflow prevention net is provided around the water intake device. When a large amount of jellyfish occurs, the jellyfish adheres to the net and reduces the amount of water intake. In addition, in the third and fourth means, the jellyfish near the water intake is to be collected, so that a large amount of jellyfish is not sucked into the water intake. Is very difficult.

る。The present invention is intended to solve such a problem. That is, the present invention, even if jellyfish is generated in large quantities, or even if a large amount of trash is floating in the sea,
It is an object of the present invention to provide an underwater suspended solids removal device that prevents jellyfish, dust, and the like from being sucked into a cooling water intake port and does not reduce the amount of cooling water.

きノズル管とを備えているものとした。In order to achieve the above object, an apparatus for removing suspended matter in the sea of the present invention includes a plurality of guide pillars that are erected in front of a cooling water intake port and whose upper end protrudes higher than the sea surface, and a tide that hangs downward. A float that has a return plate and is guided by the guide columns and moves up and down according to the vertical fluctuation of the sea surface, and air and air that are provided near the seabed in front of the guide columns and lift floating substances in the sea. And an upward nozzle pipe for ejecting any of the mixed fluids of water.

る。According to the present invention, since an upward nozzle pipe is provided further forward of the plurality of guide pillars erected in front of the cooling water intake port, air or a mixed fluid of air and water flows upward from the nozzle pipe. It gushes and creates an updraft, causing floating jellyfish and garbage to float near the sea surface. And
In the guide column, a float having a tide plate hanging down in the sea is guided by the guide column so as to move up and down following the vertical fluctuation of the sea surface due to ebb and flow of the tide and floats on the sea surface. Therefore, the floating substance floating near the sea surface is separated from the cooling water intake by the float and the tide plate, and tends to turn in a direction away from the sea surface. Therefore, stable water intake is possible.
