Abstract

The invention relates to the technical field of production and manufacture of boiler accessories, and discloses a silencer for a steel plant boiler. The silencer for the steel plant boiler comprises ashell, wherein a gas inlet is formed in the bottom of the shell, gas and noise generated in the boiler enter the shell through the gas inlet, the gas and noise are subjected to primary silencing on asilencing ring after being relatively cooled by a cooling plate, and then secondary and tertiary silencing are carried out on a silencing cylinder and a silencing pad to finish the silencing work ofthe boiler. Due to the fact that an air outlet arranged at the top of the shell faces upwards, dust often falls into the air outlet, the falling dust flows to dust collecting plates on the two sides after being shunted by a shunt cone, the falling dust enters the interior of the dust collecting plates from dust collecting nozzles at the tops of the dust collecting plates, and then the dust is conveyed into a dust collecting box through the vibration of sliding plates and the dust collecting plates. The silencer for the steel plant boiler is simple in structure and easy to operate, effectivelyprevents dust from falling into the silencer and has the efficient dustproof effect.

Description

technical field

[0001] The invention relates to the technical field of production and manufacture of boiler accessories, in particular to a muffler for boilers in steel mills. Background technique

[0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the combustion process, and then the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. During the operation of the boiler, it will generally generate a large amount of energy. The noise of the shell will seriously affect the health of the staff. Therefore, a muffler is often connected to the top of the boiler to eliminate the noise generated by the boiler and reduce the harm to the staff and the pollution to the environment.

[0003] Most of the existing silencers for boilers only pay attention to the noise reduction effect of the silencer, but ignore the dustproof effect of the silencer...
