Diesel Exhaust Silencer

Internal combustion engines all make noise, while some make more or less than others. The engine intake and exhaust are two of the most important causes of engine noise. Silencers are commonly used at the intake and diesel exhaust silencer to handle airborne noise for noise reduction. In this catalog, we have described numerous models of silencers that will meet most silencing needs.

The function of a diesel exhaust silencer is to reduce the amount of noise produced by the engine. In our atmosphere, an engine without a silencer will produce an uncomfortable level of exhaust noise. Unwanted sound is referred to as noise. Sound is a pressure wave created by alternating high and low air pressure pulses.

Special silencers can be designed to meet unique needs in circumstances when normal construction silencers do not meet the application. The reactive type, or chamber structure silencers, are the most often used silencers for internal combustion engines. Diesel exhaust silencer relies heavily on area change to reflect sound energy back to the source and makes use of expansion chambers and perforated tubes’ attenuation capabilities. Most applications, such as diesel generator sets, diesel engines, engine-driven packages, stationary industrial engines, and so on, will be covered by the silencers specified below.

Silencer Type and Size Selection

It is critical to choose and size the silencer correctly to guarantee that pressure drop, acoustic performance, and other design parameters are met. The type of engine, the ultimate usage of the engine, and the degree of silencing required all influence the choice of engine intake and Diesel Exhaust Silencer. In addition, the silencer size chosen must support the specified volume of exhaust diesel flow while maintaining backpressure within the engine manufacturer’s specifications.

  • Industrial Grade 
  • Commercial Grade
  • Semi-residential grade
  • Residential Grade 
  • Critical Grade 
  • Hospital Grade or Super Critical

The amount of exhaust flow is an important component to consider when sizing the silencer. The open flow area within the silencer must be large enough to handle the exhaust flow while not exceeding the engine manufacturer’s backpressure allowance. If the silencer is far too huge, the exhaust noise just flows through, attenuated only by the first massive expansion. Insufficient silencer size, on the other hand, may result in power loss and possible engine damage.

Mining Noise Control

For many years, noise has been regarded as an issue in the mining industry, and throughout the last century, increased mechanization has resulted in rising noise levels in various industries. The face regions of underground coal mines and coal preparation plants are the most crucial areas to pay attention to when it comes to hazardous mining noise. Mine surfaces, on the other hand, tend to provide a lower direct risk to employees.

In the complex, dynamic environment of mining, noise can be generated by a variety of equipment or operations. Drilling, blasting, cutting, materials handling, ventilation, crushing, conveying, and ore processing are all examples of this. Electrical locomotives, haulage trucks, loaders, longwall shearers, chain conveyors, continuous miners, load-dumpers, fans, and pneumatic percussion tools are also problematic. Pneumatic percussion drilling, in particular, is a significant source of the noise.

Impact noise from drill bits and mechanical vibration from drill casings, as well as impulse noise from exhaust and ancillary equipment like fans and blowers for mine ventilation, can all contribute to noise. In the mining business, there appears to be no end to the variety of noise-making equipment in use.To make matters even more complicated, the influence of any given piece of equipment may vary depending on the stage of a mining project’s lifecycle (i.e., exploration, mine development, mine operation, decommissioning, and land rehabilitation).In the early stages of a mining project, certain noise-generating equipment may be more problematic.

Reduced exposure time is one easy and effective strategy to avoid mining noise control hearing damage in mining employees. The risk of permanent hearing impairment is reduced when an individual spends less time in a noisy environment. Such restrictions should be implemented wherever practicable to ensure worker health and safety. However, in some cases, saying it is easier than doing it. In these circumstances, lowering the noise level is the best solution. This can be done at the noise source, in the path of the noise, or at the noise receiver directly.

When it comes to mining noise control hearing loss in the mining sector, early detection and prevention are crucial for workers’ health and safety. A comprehensive noise control program that treats noise at the source, interrupts noise in its route, and shields receivers from noise typically provide the best protection. It is possible to ensure that hazardous noise is properly controlled and that noise-induced hearing loss among workers is avoided by addressing all three sites of contact throughout the lifecycle of a mining project.
