Abstract

The present invention relates to floating type energy-dissipating noise reduction equipment. It is formed from noise-reducing honeycomb plate, supporting skeleton and floating body. The noise-reducing honeycomb plate is placed on the supporting skeleton, the floating body is placed under the supporting skeleton, and the whole floating type energy-dissipating noise reduction equipment is placed in the water pool of cooling tower, and the distance of lower end of noise-reducing honeycomb plate from level of water pool is less than or equal to 200 mm. Besides, said invention also provides the concrete structures of noise-reducing honeycomb plate, supporting skeleton and floating body, and the concrete working principle of said energy-dissipating noise reduction equipment.

Description

technical field

[0001] The invention relates to a falling water noise reducing device, in particular to a falling water noise reducing device in a cooling tower of a power plant. Background technique

[0002] With the rapid development of the power industry and the continuous improvement of environmental protection requirements, the State Power Corporation has proposed specific noise indicators for newly-built cooling towers. The noise must meet the relevant national standards, and the construction of cooling towers without noise reduction facilities is not allowed. For existing cooling towers, noise reduction technical transformation must also be carried out within a time limit, otherwise production must be stopped for rectification, and the noise will not be accepted if it does not meet the standard. At present, most of the cooling towers in various power plants use fiber mesh noise reduction pads to reduce noise. Falling water directly hits the noise reduction pads. The n...
