FURNACE FOR PRODUCING GLASS FORMULATED WITH COMMON SALT (SODIUM CHLORIDE), WHICH INCLUDES A PROCESS FOR PURIFYING SILICA SAND (SIO2) AND SAID PROCESS.

摘要

The present invention describes a novel system for producing glass, which is affordable and with a reduced environmental impact. The purpose of the process is to produce common glass with economic, environmental and resources availability benefits. The economic viability is obtained by the use of Sodium Chloride in a direct form, without the expensive need of transforming the same into sodium carbonate. The environmental viability is obtained upon avoiding the emission of millions of tons of carbon dioxide, which nowadays are emitted by conventional glass factories. The viability of the raw material availability is obtained by using the byproduct of the novel form for manufacturing glass, (the hydrogen chloride) in the purification of the feldespatic sands commonly polluted with ferric components. 2NaCl +6SiO2 + Ca(OH)2= (6SiO2, Na2O, CaO) (S) +2HCl(G). Affordable formula of common glass produced in a closed furnace of graphite. Purpose of the invention: a scheme of a graphite furnace (2) made with said material for avoiding corrosion caused by gases emitted upon manufacturing common glass (3) with common salt (9).
