Three stage silencer for diesel generator.

One, use diesel generators muffler

With the progress of science and technology, industrial production of high-speed development and innovation, environmental pollution is becoming more and more serious, the noise pollution is one of them. A lot of mechanical equipment in the operation, will be making a lot of noise, in general, in addition to the engine or motor noise, engine emissions will also result in strong noise, but also far more than the engine and the motor noise is big, become the industrial production the main noise source. How to reduce the exhaust noise has become a big problem in the modernization of production.

In two, diesel generator muffler overview

My company produces three stage silencer for diesel generator, which comprises an air inlet pipe, the inner pipe, two inner clapboard, exhaust and silencing tube and exhaust cylinder, air inlet pipe center is fixed in the muffle tube 1/6, and perpendicular to the axis of the muffle tube muffle tube, at both ends of a sealing plate, the exhaust cylinder fixed to the cylinder of the muffler, silencer tube is fixed with at least two clapboards will muffle tube is divided into equal three, two layers of partition boards are fixed between a ventilation pipe and hole plates into the ventilation tube, so that the exhaust to form a G maze, finally through the outer baffle within the exhaust pipe exhaust exhaust cylinder exhaust muffler exhaust cylinder, cylinder and inner wall are filled with sound-absorbing insulation stainless steel wire mesh and a microtiter plate, using them on exhaust noise absorption and reflection of the rural land, the exhaust silencing the impedance, sound decay, so as to achieve the effect of noise silencer. In contrast to the two stage silencer and industrial silencer, Lianyungang City Hong Qi auxiliary power production is three stage silencer expansion chamber, with good, high frequency noise elimination performance; the mounting of the silencer, does not affect the working efficiency of the equipment, can ensure that the inlet and outlet patency; but larger, higher requirements for noise reduction unit using or used for noise reduction in engine room. Reducing noise of 25dBA above; but larger, suitable for reducing noise requirements of high unit used for noise reduction or room.
