Abstract

The invention relates to the technical field of sound absorption technologies and purification technologies, in particular to an air purification and sound absorption composite structure. The air purification and sound absorption composite structure comprises a micro-perforated plate substrate and air purification units, wherein a sound absorption back cavity is formed between the micro-perforated plate substrate and a mounting surface, mounting portions are arranged on the micro-perforated plate substrate, and the air purification units are arranged in the mounting portions. According to the air purification and sound absorption composite structure, the micro-perforated plate substrate is connected with the mounting surface to form the sound absorption back cavity, the sound absorption back cavity and the micro-perforated plate substrate play a resonance function, and different sound absorption requirements are met by adjusting the parameters of the micro-perforated plate substrate; and different purification requirements are met by selecting or changing the purification parameters of a filling material of the air purification units and the area ratio of the air purification units and the micro-perforated plate substrate. The air purification function is achieved while the sound absorption effect of the sound absorption structure is guaranteed, the occupancy rate of the separate use space is reduced, and optimization of the space is facilitated.

Description

technical field [0001] The invention relates to the fields of sound-absorbing technology and purification technology, in particular to an air-purifying composite sound-absorbing structure. Background technique [0002] At present, people pay more and more attention to noise pollution and air pollution. Among noise control methods, sound-absorbing materials are one of the commonly used protective measures. Among them, the micro-perforated plate structure is a sound-absorbing structure developed on the basis of perforated plates. Usually the pore diameter of the micro-perforated plate is below 1.0mm, the perforation rate is between 0.3-5%, and a sound-absorbing back cavity of a certain thickness is required. Due to the advantages of simple structure, good sound absorption effect, fire prevention, high temperature resistance, and corrosion resistance, micro-perforated panels are widely used in shopping malls, railway stations, conference rooms, theaters and other public places...
