High-temperature-resistant sound insulation board
The invention discloses a high-temperature-resistant sound insulation board which comprises a keel frame, a carbon steel plate, a first aluminum silicate fiber plate, a second aluminum silicate fiber plate, aluminum foil and a micro-perforated plate, and the carbon steel plate, the first aluminum silicate fiber plate, the second aluminum silicate fiber plate, the aluminum foil and the micro-perforated plate sequentially penetrate through the keel frame, a firstcavity is formed between the the first aluminum silicate fiber plate and the second aluminum silicate fiber plate, and a second cavity is formed between the aluminum foil and the micro-perforated plate. The obtained high-temperature-resistant sound insulation board is of a double-resonance coupling structure, the low-frequency sound absorption and sound insulation effects are improved through coupling of formants by means of resistive and resonance materials, so that the purpose of expanding the sound absorption and sound insulation frequency band is achieved, and meanwhile the high-temperature-resistant performance of the sound insulation board is improved by selecting proper materials. The high temperature resistance and the sound insulation performance are further improved through parameter design of the sound insulation plate and used materials. The sound insulation board is simple in structure, is made of common materials, and is convenient for large-scale production and application in converter stations.
本发明公开了一种耐高温隔音板，包括龙骨架和依次穿过所述龙骨架的碳钢板、第一硅酸铝纤维板、第二硅酸铝纤维板、铝箔和微穿孔板，所述第一硅酸铝纤维板和第二硅酸铝纤维板之间形成第一空腔，所述铝箔和微穿孔板之间形成第二空腔。本发明得到的耐高温隔音板具有双共振耦合结构，利用阻性和共振材料通过共振峰的耦合达到提高低频吸声和隔声效果，从而达到拓展吸声和隔声频带的目的，同时，通过选用合适的材料提高隔音板的耐高温性能。本发明还通过对隔音板和使用的材料的参数设计进一步提高了耐高温和隔音性能。本发明结构简单，使用的均为常见材料，便于大规模生产应用于换流站中。
