Abstract
The generation of local electric energy has been a growing concern on the part of large companies or isolated localities. This fact occurs for several reasons, either to avoid a high electric energy tariff at certain times, or to provide electricity to an isolated community or to decentralize the Brazilian energy matrix in which, historically, hydroelectric plants predominates, which Is subject to events that escape human control as a sudden drop in the reservoir water level. To supply this need, the use of diesel generator sets is a very practical option. However, these equipments, especially when grouped in thermoelectric plants, usually generate high levels of noise as well as a high emission rate of particles and pollutants in the atmosphere, both in many cases, outside the established norms and environmental standards for such activity. Considering the current environmental situation, in which there is a special concern with the accumulation of pollutants in the air, this work proposes to expose the results obtained from an innovative device, which have the purpose of purifying the exhaust gases of diesel generators, as well as reducing the level of noise emitted in the exhaust line. The device is compact and easy to maintain, based on the principles of industrial gas scrubbers and mufflers. This unprecedented device operate with the use of a fluid responsible to separate solid particles from the the harmful gases into the environment, reducing particulate emissions, while its geometry should reduce the energy contained in the sound waves from the combustion engine
