Description

Technical Field

[0001] The utility model relates to the technical field of nuclear power plant cooling circulating water treatment devices, and particularly relates to a foam interception and collection device. Background Art

[0002] A large amount of seawater is required for the cooling circulating water of a nuclear power plant, and the water temperature difference between the inlet and outlet is about 8 - 10 °C. Due to the large volume of the cooling circulating water, a large number of marine organisms and various algae will enter the cooling system. Under the action of mechanical collision, heat, and chemical action (disinfectant), the marine organisms and various algae in the cooling cycle will die and decompose, making the circulating cooling water contain more organic matter. The circulating cooling water is usually taken from the ocean intercepted by a grid through a booster pump at the water intake, then lifted to the condenser for heat exchange, discharged into an overflow weir, then drained into a siphon well, and finally discharged into the ocean through a drainage pipe for natural diffusion and cooling. For safety reasons, there is a certain height difference between the overflow weir and the sea level. Therefore, when the warm water after heat exchange drains from the overflow weir into the siphon well, it is inevitable to generate hydraulic jump forced aeration, forming a water flow entrainment phenomenon within a certain range. When the water flow reaches the release sea area, the bubbles will overflow the water surface and form a very stable foam, thus forming a long foam belt at the circulating cooling water discharge port. These foam belts are too long to be collected and treated centrally, and the foam in the cooling circulating water is partially enriched with a large amount of organic matter and nutrient salt components, forming a large - area and long - lasting foam area in the surrounding sea area of the nuclear power plant. This not only causes certain pollution to the surrounding sea area but also makes the public often mistakenly think that the nuclear power plant discharges a large amount of toxic and harmful pollutants into the surrounding sea area, that is, the so - called sensory pollution, which greatly affects the acceptance and recognition of the nuclear power plant by the public, especially the people in the area where the nuclear power plant is located. Therefore, it is very necessary to effectively remove the pollution of the circulating cooling seawater. However, the area where this foam belt is generated is wide and it is difficult to handle. For this reason, we propose a foam interception and collection device. Content of the Utility Model

There are multiple buoys 101, and the multiple buoys 101 are connected end to end. The fixing structure 2 includes fixing ropes 201 and anchoring blocks 202. There are five fixing structures 2, and they are evenly arranged and connected around the buoy fence 1. The buoy 101 and the rubber enclosure 102 connected thereto form a fan shape through the tension of the anchoring blocks 202 on the seabed and the fixing ropes 201, so as to effectively collect the foam floating on the sea surface and then pump it into the biochemical system for further treatment and purification. One end of the fixing rope 201 is connected to the anchoring block 202, and the fixing structure 2 is connected to the buoy fence 1 through the other end of the fixing rope 201.
