Resumo: | This work proposes the use of a distiller that uses solar energy for the production of distilled water suitable for use in chemical analysis laboratories of the Federal University of Goiás (UFG).The choice of solar distiller is due to the high incidence of solar radiation in Brazil, and because this type of equipment does not consume electricity, does not generate wasted drinking water, is easy to operate and requires low technology.A study was carried out on the intensity of radiation incident in the dry winter and wet summer period of the municipalities of Catalão, Goiânia and Jataí, where the campus of this university is located, based on the Duffie and Beckman model (2013).From the generated radiation data it was possible to determine what 20º would be the best angle for the equipment coverage, so the pilot model was built and installed at the Chemistry Institute of UFG in the city of Goiânia.With the experimental data of water temperature (Tw) and the distiller cover (Tg) recorded every hour (from 8 a.m. to 6 p.m.), the distiller's energy balance, based on the Dunkle model ( 1961), by which it was calculated the heat transfer coefficients by convection (hcw) and evaporation (hew), convective heat transfer rates (qcw) and evaporation (qew), mass transfer rate ( ew) and the efficiency of the distiller (ηi).The results obtained allowed to conclude that the coefficient of heat transfer by evaporation and its corresponding rate were higher than the coefficient of heat transfer per convection and its respective rate.The production of distilled water in winter and summer was 0.31 and kgm-2dia-1, respectively, and the distiller's maximum efficiency was 5.4% in winter and 41.33% in summer. The obtained water meets the parameters of the Brazilian Pharmacopoeia and can be used in chemical laboratories in substitution to that obtained in the electric distillers. |

Dissertação (Mestrado em Engenharia Química) - Universidade Federal de Goiás, Goiânia, 2016.http://repositorio.bc.ufg.br/tede/handle/tede/6770This work proposes the use of a distiller that uses solar energy for the production of distilled water suitable for use in chemical analysis laboratories of the Federal University of Goiás (UFG).The choice of solar distiller is due to the high incidence of solar radiation in Brazil, and because this type of equipment does not consume electricity, does not generate wasted drinking water, is easy to operate and requires low technology.A study was carried out on the intensity of radiation incident in the dry winter and wet summer period of the municipalities of Catalão, Goiânia and Jataí, where the campus of this university is located, based on the Duffie and Beckman model (2013).From the generated radiation data it was possible to determine what 20º would be the best angle for the equipment coverage, so the pilot model was built and installed at the Chemistry Institute of UFG in the city of Goiânia.With the experimental data of water temperature (Tw) and the distiller cover (Tg) recorded every hour (from 8 a.m. to 6 p.m.), the distiller's energy balance, based on the Dunkle model ( 1961), by which it was calculated the heat transfer coefficients by convection (hcw) and evaporation (hew), convective heat transfer rates (qcw) and evaporation (qew), mass transfer rate ( ew) and the efficiency of the distiller (ηi).The results obtained allowed to conclude that the coefficient of heat transfer by evaporation and its corresponding rate were higher than the coefficient of heat transfer per convection and its respective rate.The production of distilled water in winter and summer was 0.31 and kgm-2dia-1, respectively, and the distiller's maximum efficiency was 5.4% in winter and 41.33% in summer.

A escolha do destilador solar se deve à alta incidência de radiação solar no Brasil, e por este tipo de equipamento não consumir energia elétrica, não gerar desperdício de água potável, ser de fácil operação e requerer baixa tecnologia.Desenvolveu-se um estudo sobre a intensidade da radiação incidente no período de inverno seco e verão úmido dos municípios de Catalão, Goiânia e Jataí, onde estão localizados os campus desta universidade, baseado no modelo de Duffie e Beckman (2013). A partir dos dados gerados de radiação foi possível determinar do que 20º seria o melhor ângulo para a cobertura do equipamento, assim o modelo piloto foi construído e instalado no Instituto de Química da UFG na cidade de Goiânia. Com os dados experimentais de temperaturada água (Tw) e da cobertura do destilador (Tg) registrados de hora em hora (das 8 h às 18 h), pôde-se realizar o balanço de energia do destilador, fundamentado no modelo de Dunkle (1961),pelo qual foram calculados os coeficientes de transferência de calor por convecção (hcw) e por evaporação (hew), as taxas de transferência de calor por convecção (qcw) e por evaporação (qew), a taxa de transferência de massa ( ew) e a eficiência do destilador (ηi). Os resultados obtidos permitiram concluir que o coeficiente de transferência de calor por evaporação e sua taxa correspondente foram maiores do que coeficiente de transferência de calor porpor convecção e sua respectiva taxa. A produção de água destilada no inverno e no verão foram de 0,31 e 1,51 kgm-2dia-1, respectivamente e a eficiência máxima do destilador foi de 5,4% no inverno e 41,33% no verão. A água obtida atende aos parâmetros da Farmacopéia Brasileira e pode ser utilizada em laboratórios químicos em substituição à obtida nos destiladores elétricos.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2017-01-19T11:05:05Z No. of bitstreams: 2 Dissertação - Camila Teles Damasceno - 2016.pdf: 3907404 bytes, checksum: a9cca771b6433ed8e2ce2cdbf38fda60 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-01-19T11:05:30Z (GMT) No. of bitstreams: 2 Dissertação - Camila Teles Damasceno - 2016.pdf: 3907404 bytes, checksum: a9cca771b6433ed8e2ce2cdbf38fda60 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-01-19T11:05:30Z (GMT).

This work proposes the use of a distiller that uses solar energy for the production of distilled water suitable for use in chemical analysis laboratories of the Federal University of Goiás (UFG).The choice of solar distiller is due to the high incidence of solar radiation in Brazil, and because this type of equipment does not consume electricity, does not generate wasted drinking water, is easy to operate and requires low technology.A study was carried out on the intensity of radiation incident in the dry winter and wet summer period of the municipalities of Catalão, Goiânia and Jataí, where the campus of this university is located, based on the Duffie and Beckman model (2013).From the generated radiation data it was possible to determine what 20º would be the best angle for the equipment coverage, so the pilot model was built and installed at the Chemistry Institute of UFG in the city of Goiânia.With the experimental data of water temperature (Tw) and the distiller cover (Tg) recorded every hour (from 8 a.m. to 6 p.m.), the distiller's energy balance, based on the Dunkle model ( 1961), by which it was calculated the heat transfer coefficients by convection (hcw) and evaporation (hew), convective heat transfer rates (qcw) and evaporation (qew), mass transfer rate ( ew) and the efficiency of the distiller (ηi).The results obtained allowed to conclude that the coefficient of heat transfer by evaporation and its corresponding rate were higher than the coefficient of heat transfer per convection and its respective rate.The production of distilled water in winter and summer was 0.31 and kgm-2dia-1, respectively, and the distiller's maximum efficiency was 5.4% in winter and 41.33% in summer. The obtained water meets the parameters of the Brazilian Pharmacopoeia and can be used in chemical laboratories in substitution to that obtained in the electric distillers. |
