AQUA SILENCER

THIS PRESENTATION IS ABOUT AQUA SILENCER WHICH REDUCES ENVIRONMENTAL AND SOUND POLLUTION

2. INTRODUCTION The aqua silencer is the design for replace commonly used single unit silencers. It plays a major role in preventing air pollution which causes harmful effect on human beings and environment . This system reduces the dangerous exhaust gases(co, Nox and lead) coming from automobiles these emissions are controlled by the charcoal layer and lime water. The smoke or emission gases and noise level in aqua silencer is very very less than the commonly used silencers.

3. CONSTRUCTION The main component of aqua silencer is perforated tube. It consists different diameter of holes to convert increase in mass bubble to decreasing mass bubbles on perforated tube. Generally four sets of holes are drilled. The activated charcoal layer and metallic mesh covers are provided around the perforated tube.

4. parts of aqua silencer Perforated tube Non–return valve Outer shell Flange Charcoal layer

5. Perforated Tube It consist no. of holes of various diameter mainly there are four sets of holes. It is used to convert the high mass of bubble to low mass and very important activated charcoal layer is pasted on it.

6. NON-RETURN VALVE It is the most important part used to avoid the backflow of exhaust gases and water.

7. Outer Shell In outer shell the whole set up is kept inside it. It is mainly made up of steel or iron. water outlet, inlet also the exhaust tube was provide in the shell itself .

8. Flange A flange is the connection of pipe where the connecting pieces have flanges by which the parts are bolted together flange is essential part it connect the silencer to engine.

9. Charcoal Layer This layer having high absorption capacity because it having large surface area. This type of charcoal called activated charcoal.

10. 4.0 WORKING OF AQUA SILENCERS The exhaust gases from engine enters from inlet to aqua silencer then perforated tube convert high mass of bubble to the low mass of bubbles. Then this gases passes through charcoal layer which again purify the gases. When exhaust gases enter into lime water then carbon particles are precipitated to down.

11. MERITS AND DEMERITS MERITS No vibration when the engine is running. Easy to start the engine. Emission and Noise is controlled at greater level DEMERITS Lime water filling is required once in a year. Silencer weight is more comparing to conventional silencers. A dditional space is required.

12. 6.0 conclusion A n aqua silencer has more efficiency to reduce emission gases from engine. In this system fuel consumption remain same as conventional silencers because the use of perforated tube. Due to the use of water as a medium sound reduces this system having pollution free emission and smokeless. This system is very cheap. This system is used for both two wheelers and four wheelers. It plays important role in industries.

13. Thanking YOU For giving this wonderful opportunity
