Análise do captor num sistema de ventilação local exaustora para remoção de fumos metálicos de uma estação de soldagem

Abstract

In this work the problems caused by toxic gases and metallic fumes in a welding station are described, as well as a proposal to modify the captors in a local exhaust ventilation system with the purpose of promoting improvements in the operating conditions of the users. This study is characterized as a research of the type applied, with possibility of practical application, however it is also necessary to carry out an exploratory study of the existing literature for the development and modification of the captors in the ventilation system. One of the biggest problems in a welding station is the fumes that emerge from the vapors of the molten metals. These vapors are filled with impurities such as gases, metals and residues, which if aspirated by the user can cause occupational diseases. It has been theoretically found that the exchange of the captor type from the exhaust system of the welding station results in an improvement of the system providing a more pleasant environment for the persons using the laboratory. Therefore, from the equations for designing ventilation systems, the choice of a better type of captor applicable to the local exhaust ventilation system for welding fumes was achieved.
