Dimensionamento de sistema de exaustão para renovação do ar na TEMOC

Abstract

Pollution inside a factory can affect both workers and the environment. Some of the risks associated with indoor air pollution are: respiratory diseases, allergies, eye, nose and throat irritation, headaches, fatigue, nausea and even cancer. In addition, pollution inside a factory can contribute to the emission of greenhouse gases, which cause global warming and climate change. An industrial exhaust system aims to create and optimize a facility to reduce pollution from this type of environment. These systems contribute to worker health by removing gases and dust from industrial work environments, making them safe and healthy. TEMOC is a medium-sized company with a total area of 10x15m. The company is located in Maputo, Boane District, in the Beleluane industrial park, where it currently has 60 (sixty) workers, of which 2 are in automation, 18 are in electrical engineering, 20 in mechanical engineering and the remaining 20 in industrial maintenance. The air exhaust system is installed inside the factory, close to the ceiling, and will be made of metal material that can withstand long periods of time and is also flame-resistant. The system will be made of large pipes with several components spread out under the roof and will have an exhaust fan. However, a fan that best suits the project was selected, so the LMS 900 ARR.1 CL.IV fan – 3100 rpm with a flow rate of 14904 m^3/h was selected. Therefore, the exhaust system is a system that ends up being the most effective means of controlling pollution, providing its beneficiaries with better working conditions and, why not say, better living conditions.
