Abstract
An exciter-coupling sound-insulation noise-reduction ventilating hood in a steam turbine unit with hydrogen consists of an exciter hood and a coupling hood. The exciter hood and the coupling hood are formed by combining steel plates and steel frames, high-density composite sound absorbing layers and color steel sound-insulation damping sandwich plates are sequentially laminated on lateral walls and top plates of the exciter hood and the coupling hood from inside to outside, a sound absorbing and insulating inspection door is arranged on the lateral wall of the exciter hood, an air inlet noise-reduction shutter is disposed on the lateral wall, which is connected with the coupling hood, of the exciter hood, and an air outlet noise-reduction shutter is arranged on the top plate of the coupling hood. The exciter hood and the coupling hood are in split structures and can be respectively lifted up during maintenance. The color steel sound-insulation damping sandwich plates are arranged on the outer wall of a hood body, and the inner wall of the hood body consists of the high-density composite sound absorbing layers, heat dissipation is realized by the aid of natural air flow, a motor and a fan are omitted to avoid potential safety hazards, noise at the position one meter away from a hood shell is reduced to range from 78dB to 80dB, and the sound absorbing and insulating inspection door on the lateral wall of the exciter hood brings convenience for maintenance staff to enter for overhaul.
