Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-3, the present utility model provides a technical solution: a multi-dimensional turbulent exhaust muffler comprises a chimney 1 and a multi-dimensional sound absorption mechanism; the multidimensional sound absorption mechanism is arranged in the chimney 1; the multidimensional sound absorption mechanism comprises a cylindrical sound absorption block 3 which is detachably arranged on the surface of the bottom end inside the chimney 1, a plurality of vent holes 4 are formed in the lower surface of the sound absorption block 3 in a penetrating manner along the length direction of the chimney 1, and a plurality of guide blocks 5 which are staggered with each other are fixedly connected on the inner surfaces of the vent holes 4 at equal intervals along the length direction; the inside of the sound absorption block 3 is provided with a plurality of cavities 6 with different sizes, and the cavities 6 are randomly distributed in the inside of the sound absorption block 3.

In this embodiment, the inside a plurality of air vents 4 of seting up of sound absorption piece 3 can make the flue gas get into and pass through its top from its bottom, and at the in-process that the flue gas flows from air vent 4 inside, receive the influence of a plurality of water conservancy diversion pieces 5, the flue gas will form the turbulent flow shape in the inside of air vent 4 to by the speed reduction, when making the flue gas finally pass through chimney 1 top export discharge, the flue gas can not rub with the air in surrounding fast and produce the noise, thereby play the effect of making an uproar falls.

Meanwhile, the inside of the sound absorption block 3 is provided with the plurality of cavities 6, so that when the smoke collides inside the sound absorption block 3 to generate sound, the sound emitted by the smoke can continuously enter different media in the process of outwards spreading, the energy of the smoke can be effectively weakened, and the noise reduction effect can be achieved.
