The silencer, the hush tube group B, hush tube group A are disposed as " bending " type structure, and it is corresponding staggeredly It sets, sound attenuation hole B, sound attenuation hole A is respectively equipped on two partition plates among hush tube group B, hush tube group A.

The silencer, the multiple silencing channel A connect setting with silencing channel B respectively, are leaned on silencing channel B Multiple stomatas are equipped near outgassing end lid.

The silencer is covered in outlet side equipped with multiple through holes.

The silencer is equipped with cavity between outer housing and inner housing.

By adopting the above-described technical solution, the utility model has the advantages that：

Silencer described in the utility model by expanding the external setting baffle of stream cavity, is set in the middle part of inner housing Put partition plate, baffle with the hush tube group A, the hush tube group B that connects setting, and hush tube group A, hush tube are set respectively on partition plate Group B interlocks and is oppositely arranged, and while extending silencing channel, ensure that exhaust circulation, effectively accelerates boiler pressure release speed, It ensure that qualified displacement noise.
