Description
Technical Field
The utility model belongs to the technical field of the ventilation noise elimination, concretely relates to rain-proof noise eliminator of binary channels.
Background
At present, noise generated by a ventilation fan of an industrial factory building is mainly treated by installing a silencer. Because the mode of fan installation on the roof is mostly adopted in the industry factory building, satisfies the ventilation requirement, consequently, also set up on the roof to the silencer of fan installation. However, the internal silencing structure of the silencer is mostly made of non-waterproof materials, and the silencer elbow or the structure with the rainproof cap on the top of the silencer is mostly adopted as a silencing device of the fan so as to meet the functions of silencing and preventing rain.
The silencing elbow has the defects that the air flow direction can be changed only in a single direction and the silencing channel is long as the double-channel rainproof silencing device, and the structure of the silencer with the rainproof cap additionally arranged at the top has the defects of complex structure and poor integrity. Therefore, a dual-channel rainproof muffler device which can flexibly change the direction of air flow, has relatively short muffling channels and good structural integrity of the muffler is needed to enhance the applicability of the muffler.
