Abstract

The invention discloses a gas diffusion silencer, which comprises a shell, a diffusion cap arranged at the top of the shell and an ash discharge door arranged at the bottom of the shell, wherein the shell is divided into multiple sections, a plurality of movable sound absorption sheets are arranged in the shell sections, and sound absorption sheet changing doors are arranged on the shell sections outside the movable sound absorption sheets. The gas diffusion silencer has the advantages that: the integral silencer is sectioned, and the original silencer of several tons is split into small components of hundreds of kilograms, so that the silencer is conveniently carried to the top of a blast furnace; and the internal sound absorption sheets are designed into the movable sound absorption sheets, so that the internal sound absorption sheets can be changed without integral decomposition.

Description

technical field [0001] The invention relates to a muffler, in particular to a gas dispersing muffler. Background technique [0002] Existing blast furnace gas diffuser mufflers generally adopt an integral structure, and the sound-absorbing sheet is installed in the casing of the gas diffuser muffler. Since the muffler is installed at a height of tens of meters, it is difficult to replace the sound-absorbing sheet afterwards; in addition, the integral muffler, The weight is very heavy, which is not convenient for transportation and installation. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a gas dissipation muffler with easy replacement of sound-absorbing sheets and light structure. [0004] The technical scheme adopted in the present invention: [0005] The gas diffuser muffler consists of a shell, a release cap on the top of the shell and ...
