Direct cooling type circulating water drainage open channel defoaming device

Abstract

The invention discloses a direct cooling type circulating water drainage open channel defoaming device which comprises a water spraying pipeline and a supporting plate, the water spraying pipeline isarranged on the supporting plate, small water spraying holes with set angles are evenly distributed in the lower side of the center line of the water spraying pipeline, and small columnar water flow can be generated and sprayed to the water surface. Original foam can be effectively removed, and new foam cannot be generated; and the supporting plate floats on the water surface and can intercept foam on the water surface, so that the foam on the water surface close to the wood plate can be timely and effectively removed under the water spraying condition. The direct cooling type circulating water drainage open channel defoaming device is simple in structure, low in manufacturing cost, economical, practical, free of personnel on duty, capable of effectively removing foam on the water surfaceand capable of reducing negative effects on the environment and ecology, and only whether abnormity exists or not is inspected, and operation is not needed.

Description

technical field [0001] The invention relates to the technical field of water, waste water and sewage treatment, in particular to a direct cooling circulating water drainage open channel defoaming device. Background technique [0002] Circulating water is a particularly important heat exchange system for power plants and chemical projects. Most projects are designed to directly take seawater to exchange heat with condensers or closed-loop circulating water in chemical process equipment. After heat exchange, the seawater is directly discharged to the sea. 36-40°. Usually, 1-3ppm fungicides will be added to the circulating water, so that microorganisms and marine organisms in the water will not adhere to the equipment and the inner wall of the pipeline. Most of the microorganisms die after adding fungicides, and are decomposed into organic matter by heat exchangers, which are mixed with sediment and discharged out of the system. The water surface foam in the drainage increases...
