Mute clean room with labyrinth type air duct
The invention belongs to the field of noise reduction of clean rooms, and particularly discloses a mute clean room with a labyrinth type air duct, which comprises an outer layer wall plate, an inner layer wall plate, a filter layer, a raised floor, an air supply box and a top plate, an internal space formed by the inner-layer wall plate is divided into a static pressure cavity, a clean room inner cavity and an air return cavity by the filter layer and the raised floor; the air supply box penetrates through the outer-layer wall plate and the inner-layer wall plate and extends into the static pressure cavity; an air return opening is formed in the side wall of the bottom of the inner-layer wall plate, so that a gap between the outer-layer wall plate and the inner-layer wall plate forms an air return channel; the top plate is fixed to the top of the outer-layer wall plate, a gap is reserved between the top plate and the outer-layer wall plate to form an air outlet channel, and the top of the outer-layer wall plate is open. By the adoption of the double-layer wall body, external sound can be effectively isolated, meanwhile, the air return channel and the air outlet channel form the labyrinth type air channel with the long path, air noise can be further reflected and absorbed, and then the good mute effect is achieved.
本申请属于洁净室降噪领域，具体公开了一种设有迷宫式风道的静音洁净间，包括外层墙板、内层墙板、过滤器层、高架地板、送风箱和顶板，其中：外层墙板与内层墙板采用隔音材料制成并构成双层墙体，内层墙板形成的内部空间被过滤器层和高架地板分隔成静压腔、洁净间内腔和回风腔；送风箱穿过外层墙板和内层墙板伸入静压腔内部；内层墙板的底部侧壁开设有回风口，使得外层墙板与内层墙板的间隙构成回风通道；顶板固定在外层墙板的顶部并与外层墙板之间留有缝隙以形成出风风道，外层墙板的顶部开口。本申请采用双层墙体能够有效隔绝外部声音，同时通过回风通道与出风通道构成路径较长的迷宫式风道，能够进一步反射吸收风噪，进而取得较好的静音效果。
