Diseño y construcción de un sistema de ventilación y medición de gases producidos en la cámara de inflamabilidad del Laboratorio de Ingeniería Mecánica de la Universidad Técnica de Ambato

Abstract

Safety afety in the work environment as well as control of gaseous emissions towards the environment are trends in the modern industrial environment, since it seeks to implement processes that are friendly to the environment and minimize the impact on it, which is why This technical project constitutes the study of design and construction alternatives for a localized extraction system for the horizontal and vertical flammability chamber of the Faculty of Civil and Mechanical Engineering, as well as determining the degree of contamination in parts per million that is generated by test a material in said chamber. The necessary parameters were established for the design and construction of the localized ventilation system based on the ACGIH (AMERICAN CONFERENCE OF GOVERNMENTAL INDUSTRIAL HYGIENISTS) standard, such as height, density and temperature of gases, flow rates, etc. The necessary conditions were identified to carry out the combustion test and the emission of combustion products gases in stationary sources as established by NT 001 and EPA PART 60 appendix A. Then, materials in the flammability chamber were tested to verify the proper functioning of the extraction system and perform a combustion test based on EPA PART 60 APPENDIX A METHOD 3A, 6C, 7E, considering the characteristics of the Insigth Fyrite Plus Gas Analyzer. With the tests carried out it was found that the material composed of resin and natural fiber reinforcement has a concentration of 8 PPM of 𝐶𝑂2 (corresponding to 14.39 mg / m3) an average temperature of 23.22 grade C and 20.9 percent of 𝑂2,, with a gray-dark color, the material composed of polyester resin and fiberglass reinforcement has a concentration of 3 PPM of 𝐶𝑂2 (corresponding to 5.4mg / m3), an average temperature of 23.13 grade C and 20.9 percent of 𝑂2,, with a gray color, the microsuede material (corosil), has a concentration of 11 PPM of 𝐶𝑂2 (corresponding to 19.79 mg / m3), an average temperature of 18.03 grade C and 20.9 percent of 𝑂2,, With a gray-dark coloration, the alcantara material has a concentration of 3 PPM of 𝐶𝑂2, (corresponding to 5.4 mg / m3) an average temperature of 20.91 grade C and 20.9 percent of 𝑂2,, with a gray coloration.
