Abstract
The utility model provides a cooling tower silencer of adjustable flow area and sound attenuation, include: steel structure, silencer and control system, the steel structure sets up in the both sides of silencer for installing silencer, the silencer includes: shell, sound attenuation piece, pin shaft, the shell presents the " mouth " character, sound attenuation piece is fixed in the inside of shell through pin shaft, rotates with pin shaft as center, sound attenuation piece realizes the adjustment of opening angle and flow area through control system. Through rotatable sound attenuation piece and control system, realize according to diurnal noise standard difference and cooling tower ventilation demand, dynamically adjust sound attenuation effect and flow area, thereby under the premise of guaranteeing the noise reduction to reach the standard, optimize cooling tower operation efficiency, and reduce land occupation and cost.
