A kind of multifunctional and environment-friendly bsk sintering technology vertical kiln and its application method

Abstract

The invention relates to the field of non-metallic ore sintering shaft kilns, in particular to a multifunctional environmentally-friendly BSK sintering technology shaft kiln and a use method of the shaft kiln. The shaft kiln comprises an inner sleeve ring cooler, an inner sleeve ring tray, an inner sleeve ring, an outer sleeve ring, a kiln shell, a cooling wind feeding fire bridge, a hot air discharging fire bridge, combustion product feeding fire bridges, combustors with combustion channels and a ring type gravity gas-powder separator. New sintering kiln design thoughts includes that a combustion and heat transfer process analysis separation technology is adopted; a heating bridge technology is adopted for sintering in the kiln; a ring type material channel technology is adopted for all segments in the kiln; and a boiling fluidization technology is adopted for the cooling segment in the kiln. According to the multifunctional environmentally-friendly BSK sintering technology shaft kiln, the particle size application range of a non-metallic ore sintering material is wide, product quality is good, the yield is high, and energy conservation and environment protection are achieved; andthe problems of the product output, quality, energy consumption and environment protection of products produced by the sintering industry of non-metal ores such as limestone, magnesite, light calciumcarbonate, dolomite, kaolin and blue carbon can be solved.

Description

technical field [0001] The invention relates to the field of non-metallic ore sintering shaft kilns, in particular to a multifunctional and environment-friendly BSK (BSK means Bridge-Shaft-Kiln, meaning bridge-shaft-kiln) sintering technology shaft kiln and a method for using the same. Background technique [0002] At present, the distribution of magnesite in the world is mainly in China, while the distribution of Chinese magnesite is mainly in Yingkou, Dashiqiao and Haicheng areas in the south of Liaoning. With the development of science and technology, the demand for magnesium products is increasing day by day, and the types and quality of magnesium products are also constantly improving, and the initial products of these products are finished products. [0003] Light-burned magnesia is a representative magnesia product. It is an important intermediate product for the production of various qualities of mid-range magnesia, high-grade magnesia and fused magnesia. The quality...
