A kind of vertical boiler exhaust muffling device, including hush pipe, left support leg, right support leg, air inlet pipe, hush pipe, interior anechoic chamber, outer anechoic chamber, breather pipe, resistance tone chamber, blast pipe, the hush pipe bottom is supported by left support leg, right support leg；The hush pipe bottom middle device air inlet pipe, the internal hush pipe of air inlet pipe joint noise reduction cylinder, the noise reduction pipe device is inside interior anechoic chamber, shown interior noise reduction chamber device is inside outer anechoic chamber, the outer noise reduction chamber device is in hush pipe interior lower end, the hush pipe inner upper end device hinders tone chamber, and the outer anechoic chamber top passes through three breather pipe connection resistance tone chamber bottoms；Resistance tone chamber top device escape pipe；Lower end device blast pipe on the right side of the hush pipe, the outer anechoic chamber bottom right-hand unit drainpipe, the drainpipe other end mouth of pipe passes hush pipe bottom surface.
The hush pipe is the straight tube that multiple manholes are set on pipe face.
The multiple oval hollow holes of device on the wall of the interior anechoic chamber.
The outer noise reduction chamber interior walls are sound-absorbing inwall, and inwall is made up of silencing cotton.
Resistance sound diaphragm plate of the resistance tone chamber interior arrangement polylith with hollow out mouthful.
Interior arrangement elastic caoutchouc inwall in the hush pipe.
Beneficial effects of the present invention：A kind of vertical boiler exhaust muffling device of the present invention,
Sound deadening capacity is big, soundproof effect is good, can meet the requirement of relative national standards, has the advantages that compact conformation, processing and fabricating are easy, is suitable for large-scale promotion and uses.
The present invention in use,
Boiler Steam is entered to inside hush pipe from air inlet pipe first, is entered to after the porous scattered sound on hush pipe in interior anechoic chamber, through on interior anechoic chamber's wall
Oval hollow hole is entered to inside outer anechoic chamber after dissipating sound, inside outer anechoic chamber's interior arrangement silencing cotton, partial noise can be eliminated, then gas is entered to inside resistance tone chamber by breather pipe, stop by polylith sound blocking baffle, in order to eliminate the impulse force of Boiler Steam, further abate the noise, then entered to from escape pipe inside hush pipe, constantly buffer by hush pipe inner elastomeric rubber inner wall, after the noise that rebounds, discharged through escape pipe, sound deadening capacity is big, soundproof effect is good, reaches relative national standards.
