Abstract
The utility model discloses a sound reducing and insulating device for a boiler system, which comprises a box body, a sound absorbing plate and a flange, wherein the flange is arranged at the bottom end of the box body and is fixedly arranged on an exhaust port of a boiler; an exhaust port is formed on the box body; and the sound absorbing plate is arranged on the inner wall of the box body and is welded on the inner wall of the box body in a spiral plate shape. In the sound reducing and insulating device, the sound absorbing plate is arranged on the inner wall of the box body and has a spiral sheet structure, and air entering the box body is blocked by the sound absorbing plate to reduce the circulating speed of the air in the box body, so the aim of sound reduction is fulfilled. The sound reducing and insulating device has small volume and is easy to mount.
Description
Technical field
The utility model relates to a kind of steam generator system flat sound arrester.
Background technology
The flat sound arrester is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Silencer is mounted in air force equipment, as the device of the reduction noise on the gas channel of air blast, air compressor machine or in the inlet and exhaust system.Silencer can stop the propagation of sound wave, allows the air communication mistake, is the effective tool of control noise, and in existing technology, the device kind of sound insulation flat is a lot, mostly complex structure, involve great expense maintenance and cleaning difficulty.
The utility model content
The utility model provides that a kind of sound deadening capacity is big, volume is little, structure is simple and direct, easy for installation, be easy to safeguard, steam generator system flat sound arrester.
The utility model technical solution problem provides following scheme:
A kind of steam generator system flat sound arrester, comprise casing, acoustical plate, flange, the bottom of described casing is provided with flange, described flange is fixedly mounted on the exhaust outlet of boiler, exhaust outlet is established in described casing upper end, described cabinet wall is provided with acoustical plate, and described acoustical plate sheet in the shape of a spiral is welded on the inwall of casing.
The utility model adopts installs acoustic board on cabinet wall, described acoustic board is the helical structure of sheet, after air enters into casing, be subjected to stopping of acoustical plate, can reduce the velocity of liquid assets of air in casing like this, thereby reach the purpose of flat, volume of the present utility model is little, and is easy to install.
