Fabricación de un Concentrador Solar Parabólico Compuesto (CPC) para desinfección de agua de consumo en Comunidades Rurales

Abstract

This paper presents the selection of supply materials and describes the manufacturing process of a solar compound parabolic solar concentrator (CPC) to disinfect drinking water for consumption by rural communities. The volume of water to be treated is 100 liters/day, average amount of water for services of a family of 6 people, including washing of kitchen utensils and food preparation. The selection of supply materials for the CPE manufacture was made considering the lifetime, low cost and availability in the Mexican industrial market. The main components of the CPC are: 1. the profile of the involute, made of galvanized steel sheet gauge 20 (0.9 mm) with bright chrome finish to achieve a reflective surface, 2. Hydraulic system, integrated by coupling elements between 6 lines of borosilicate glass tubes of 44 mm outside diameter and 1.6 mm thickness with PVC accessories and 3. Mechanical support structure of the CPC, which was designed with a variable angle, to adjust according to the latitude of the operation site, this was manufactured with industrial processes of pailería and reinforced tubular profile (PTR) of 14 gauge steel (1.9 mm thickness) was used.
