Production method for preparing composite particle glass raw material by utilizing silica powder waste and application thereof

Abstract

The invention discloses a production method for preparing a composite particle glass raw material by utilizing silica powder waste and application thereof. The production method is carried out sequentially according to the steps of weighing and preparing materials, pickling and removing iron, stirring and preparing slurry, pressing by a machine to pelletize, air-drying and dehydrating, stacking and curing, sieving and sorting and the like. The silica powder waste and cheap light soda ash are recycled to perform the reaction so as to prepare the composite particle glass raw material. The high-quality raw material which has regular and uniform prefabricated particle size, low melting point and very low iron content and meets the requirement of a high-end glass product is provided. The glass production method can be greatly optimized. The production method has obvious effects of improving the quality of the glass product and reducing the production cost. Two technical difficult problems of high energy consumption and high manufacturing cost which are caused by pollution of waste fine silica powder to the environment for a long time in the silica industry and high consumption of dense soda ash of glass production enterprises are well solved. The production method has great social effects of saving energy, reducing emission and protecting the environment and great economic benefits and has excellent popularization and application prospects.

Description

Technical field: [0001] The invention relates to a method for harmless treatment and comprehensive utilization of silica sand fine powder waste, which belongs to the technical field of energy saving, emission reduction and environmental protection engineering, in particular to a production method for preparing composite particle glass raw materials from silica sand waste and its application. Background technique: [0002] We know that silica sand (also known as: quartz sand) is an important industrial mineral raw material, and its main chemical composition is SiO 2 , and contains Al 2 o 3 , CaO and other mineral impurities, it is the main bulk raw material for the production of glass products. As far as the production process of its glass products is concerned: it uses granular heavy soda ash and silica sand that meets the particle size requirements (feldspar or dolomite and other raw materials can be added according to the needs of the production process) and the require...
