Broadband silencer and pressurization system for pressurized building
The invention discloses a broadband silencer for a pressurized building and a pressurization system. The broadband silencer for the supercharged building comprises a functional pipe section and connecting pipe sections located on the two sides of the functional pipe section, the side, close to supercharging equipment, of the functional pipe section is in the inlet direction of the functional pipe section, the side, away from the supercharging equipment, of the functional pipe section is in the outlet direction of the functional pipe section, and the interior of the functional pipe section is completely filled with multiple silencing sections in the length direction. Each silencing section is made of a porous material, the length of the silencing section in the direction from the inlet to the outlet of the functional pipe section is gradually reduced, and the pore diameter of the porous material is gradually reduced. According to the broadband silencer for the supercharged building, the functional pipe section is completely filled with the porous material, the silencing effect is guaranteed according to the material sound absorption principle, the silencer is used in cooperation with supercharging equipment, pressure loss caused by the porous material can be ignored, and therefore the silencing effect is greatly improved. According to the silencer, the silencing effect can be guaranteed under the condition of small size, and meanwhile efficient silencing can be achieved.
本发明公开了一种用于增压建筑的宽频带消音器和增压系统。本用于增压建筑的宽频带消音器，包括功能管段以及位于功能管段两侧的连接管段，其中，功能管段靠近增压设备一侧为其入口方向，远离增压设备一侧为其出口方向，功能管段内部长度方向上完全填充有多段消音段，每段消音段由一种多孔材料组成，功能管段的入口至出口方向消音段的长度逐渐减少且多孔材料孔径逐渐减少。本发明提出的用于增压建筑的宽频带消音器，通过在功能管段中完全填充多孔材料，采用材料吸音原理来保证消音效果，因本消音器是配合增压设备来使用的，多孔材料带来的压损可以忽略不计，因此，本消音器可以在小体积的情况下保证消音效果，同时，可实现高效消音。
