Detailed Description

As shown in fig. 1 and 2, a silencer for an exhaust gas treatment device includes a silencer duct 100 and a silencer assembly 200, wherein both ends of the silencer duct 100 are respectively provided with an air inlet 110 and an air outlet 120;

the silencing assembly 200 comprises two silencing plates 210 which are arranged in parallel, the silencing plates 210 are transversely arranged in the pipe of the silencing pipe 100, through holes 211 are formed in the two silencing plates 210, the through holes 211 in the two silencing plates 210 are arranged in a staggered mode, and the pipe cavity of the silencing pipe 100 is sequentially divided into an air inlet chamber 410, a silencing chamber 420 and an air outlet chamber 430 from the air inlet 110 to the air outlet 120 by the two silencing plates 210;

a plurality of hydrophobic sound-absorbing elements 500 are arranged in the air inlet chamber 410 and the air outlet chamber 430, and the sound-absorbing elements 500 are arranged along the axial direction of the silencing pipe 100;

the lowest parts of the inlet chamber 410, the silencing chamber 420 and the outlet chamber 430 are all provided with the liquid leakage pipe 300.

After the exhaust gas enters the muffler pipe 100 from the inlet 110, the exhaust gas first passes through the inlet chamber 410, and a plurality of sound-absorbing members 500 are disposed in the inlet chamber 410 in the axial direction of the muffler pipe 100, so that noise of the air flow is primarily absorbed when the air flow passes through the sound-absorbing members 500.

The exhaust gas then flows through the muffling chamber 420, and the flow of air is continuously reflected between the two muffling plates 210 to dissipate the noise energy, thereby reducing the acoustic energy. The through holes 211 on the two sound-absorbing plates 210 are arranged in a staggered manner, so that the residence time of the air flow in the sound-absorbing chamber 420 can be prolonged, the energy consumption of noise is improved, and the sound-absorbing effect is good.

The air flow enters the air outlet chamber 430 after passing through the sound-deadening chamber 420, and the noise in the air flow is absorbed again by the sound-absorbing member 500 in the air outlet chamber 430, thereby further reducing the noise.

The airflow is subjected to multi-stage noise reduction through the air inlet chamber 410, the silencing chamber 420 and the air outlet chamber 430, so that the noise in the airflow is effectively reduced, and the noise reduction effect is good.

The sound-absorbing element 500 is made of hydrophobic sound-absorbing element 500, when water vapor is condensed into water, the water cannot be absorbed by the sound-absorbing element to pollute the sound-absorbing element, and after the water vapor is condensed into water, the water vapor flows to the bottom of the silencing pipe under the action of gravity and is discharged out of the silencing pipe 100 through the leakage pipe.

The sound-absorbing member 500 is detachably installed in the silencer duct 100 in an aligned manner, and after a long time use, the service life of the silencer duct 100 can be prolonged by replacing the sound-absorbing member 500 with a new one.

In the process of installing the sound absorbing element 500, the silencing sheet 510 is first clamped in the clamping groove of the clamping groove member 520, then the silencing sheet 510 is inserted into the silencing pipe 100 from the insertion hole at the top of the silencing pipe 100, and meanwhile, the insertion hole is blocked by the clamping groove member 520, so that gas leakage is avoided.

As shown in fig. 3, the sound-deadening sheet 510 includes an inner layer of ultra-fine glass wool 511, a hydrophobic cloth 512 wrapping the ultra-fine glass wool 511, and an outermost layer of a micro-porous plate 513.

The superfine glass wool 511 has the advantages of light weight, good sound absorption performance, corrosion resistance, heat resistance and good chemical stability. The superfine glass wool 511 is arranged in the water repellent cloth 512, so that water is prevented from invading the superfine glass wool 511, and the superfine glass wool 511 is prevented from being corroded and polluted. The silencing sheet 510 is pressed into a square block through the outermost microporous plate 513.

In order to replace the sound absorbing member 500, when the handle 522 is provided on the top of the clip member 520 and the sound absorbing member 500 needs to be replaced with a new one, the worker pulls the handle 522 to take out the sound absorbing member 500, replaces a new silencing sheet, and then reinserts the silencing sheet into the silencing pipe 100.

Further, as shown in fig. 4, a plurality of convex balls 212 are provided on the opposite surfaces of the two sound-absorbing plates 210.
