Resumen
El presente trabajo se realizó en la UEB David Díaz Guadarrama, en la ciudad de Santa Clara, la cual se dedica al recape de neumáticos. El mismo tuvo como objetivo cuantificar los niveles de dióxido de azufre del aire con el uso de sensores de bajo costo en el radio higiénico sanitario de la fábrica. Para ello se evaluó el escenario base de emisión de óxidos de azufre en el sistema de generación de vapor. Se determinaron experimentalmente las concentraciones de aire limpio y se cuantificaron los niveles de inmisión de SO2 en la zona de protección sanitaria con el uso de sensores de bajo costo tipo Alphasense. Los resultados obtenidos, muestran que la arquitectura propuesta, basada en hardware, softwares gratuitos y sensores calibrados a bajo costo es adecuada para su uso en aplicaciones de medición de la calidad del aire. Además, la calibración del aire cero mediante la adsorción con carbón activado es factible, obteniéndose como mejor relación H/D de la columna 4 cm y flujo moderado. Los niveles más significativos de emisión CO2 y SO2 están en correspondencia con la calidad de la materia prima y con la estequiometría de la reacción de formación de óxidos de carbono. Los niveles de SO2 en el aire ambiental fueron de alrededor de 36 ug/m3 y los modelos de dispersión de la emisión de la fuente estudiada demuestran que la calidad del aire por el efecto de este contaminante es aceptable.
This work was carried out at the David Díaz Guadarrama UEB, in Santa Clara city, which is dedicated to tire recovery. The objective was to quantify the levels of sulfur dioxide in the air with the use of low-cost sensors in the sanitary hygienic radio of factory. For this purpose, the base scenario of sulfur oxide emissions in the steam generation system was evaluated. Experimental clean air concentrations were determined and SO2 immission levels were quantified in the sanitary protection zone with the use Alphasense low-cost sensors. The results obtained show that the proposed architecture, based on hardware, free software and low-cost calibrated sensors, is suitable for use in air quality measurement applications. In addition, the calibration of zero air by means of adsorption with activated carbon is feasible, obtaining as best H/D ratio of the column 4 cm and moderate flow. The most significant CO2 and SO2 emission levels are in correspondence with the quality of the raw material and with the stoichiometry of the carbon oxide formation reaction. The SO2 levels in the ambient air were around 36 ug/m3 and the emission dispersion models of the studied source show that the air quality due to the effect of this pollutant is acceptable.
