چکیده

باتوجه به دسترسی آسان به انرژی خورشید، تصفیه آب با استفاده از انرژی خورشید موردتوجه پژوهشگران می‌باشد. در این پژوهش، یک دستگاه آب‌شیرین‌کن خورشیدی پلکانی ساخته شده و در شهر اراک موردمطالعه آزمایشگاهی قرار گرفته است. به همین منظور، تأثیر پنج متغیر ورودی بر میزان استحصال آب به‌عنوان متغیر خروجی، با استفاده از طراحی آزمایش به روش تاگوچی بررسی شده است. متغیرهای ورودی شامل دبی آب ‌شور، زاویة دستگاه، رنگ صفحة جاذب، تعداد و فاصلة نخ‌های هدایت‌کنندة آب تقطیرشده در هر ردیف بوده‌اند. این تحقیق ازاین‌جهت منحصربه‌فرد است که از نخ‌های پلاستیکی برای ایجاد مسیرهایی بر روی سطح شیشه استفاده کرده تا آب تقطیر شده را به مخزن آب شیرین هدایت کند. همچنین بررسی هم‌زمان تأثیر پارامترهای ورودی از نوآوری‌های این پژوهش می‌باشد. بر اساس نتایج به‌دست‌آمده، بیشترین خروجی آب شیرین، به میزان 1975 میلی‌لیتر بر مترمربع، زمانی حاصل می‌شود که دبی ورودی آب شور 50 میلی‌لیتر بر دقیقه، زاویة دستگاه 40 درجه، رنگ صفحة جاذب مشکی، تعداد نخ‌های هدایت‌کنندة آب در هر ردیف 2 عدد و فاصلة ردیف‌ها 8 میلی‌متر باشد. همچنین استفاده از 2 عدد نخ‌ هدایت‌کنندة آب در هر ردیف و به فاصلة 8 میلی‌متر از همدیگر سبب افزایش میزان استحصال آب بر واحد سطح شده است.

چکیده [English]

Academics are interested in solar energy for water purification because it is easily accessible. In this investigation, a stepped solar still was constructed and tested experimentally in Arak. Using the Taguchi design of experiment approach, it was determined how the five input parameters-saline water flow rate, device angle, absorber plate color, number, and spacing of distilled water-conducting threads in each row-affected the amount of freshwater production as the output variable. This research is unique in that it uses plastic threads to create channels on the cover glass surface that lead distilled water to the freshwater tank. In addition, the simultaneous study of the effect of input parameters is one of the innovations of this research. The results showed that when the input saline water flow rate was 50 ml/min, the device angle was 40°, the absorber plate was black, the number of water-conducting threads in each row was 2, and the row spacing was 8 mm, the greatest freshwater output of 1975 ml/m2 was produced. Also, by using two water-conducting threads in each row and spacing them 8 mm apart, the amount of water produced per unit of surface area was increased.
