Summary
Com o objetivo de fornecer água potável aos agricultores do Semiárido do Nordeste Brasileiro, estudou-se a viabilidade técnica de um destilador solar no processo de dessalinização de água para consumo humano constituído de um coletor solar para aquecimento de água salina. Foram avalizados dois métodos de condução do fluxo de água do coletor solar para o tanque de evaporação. No Método 1 (M1) o fluxo de água foi constante (1L h-1), mantendo-se um lâmina de 10mm no interior da caixa de alvenaria. No Método 2 (M2) o fluxo de água, advindo do coletor solar, ocorria apenas às 15 horas quando o destilador/condensador era abastecido com água quente advinda do coletor solar, e após o abastecimento o fluxo de água era interrompido. Os volumes de água destilada produzida no sistema são suficientes para atender as necessidades de água destinada ao consumo direto de uma família na zona rural. Em termos médios a produção de água destilada por radiação solar incidente no sistema em M2 foi 46,87% maior que em M1.
Summary translation
With the goal of providing potable water to farmers in the semiarid northeastern Brazil, we studied the technical feasibility of a solar still in the process of desalination of water for human consumption consisting of a solar collector for heating water saline. Two methods were backed driving the flow of water from the solar collector to the evaporation pan. In Method 1 (M1) the water flow was constant (h-1 L 1), maintaining a 10mm slide within the masonry box. In Method 2 (M2) the flow of water coming from the solar collector, occurred only at 15 hours when the distiller / condenser was filled with hot water that comes from the solar collector, and after supplying the water flow was stopped. The volumes of distilled water produced in the system are sufficient to meet the needs of water for direct consumption of a family in the countryside. On average the production of distilled water for solar radiation incident on the system M2 was 46.87% higher than in M1.
