Abstract

The invention discloses a pure oxygen combustion system for rock wool melt temperature multi-point accuracy control, and solves the technical problems that in the conventional rock wool production process, the melting strength of a product is insufficient, the acidity coefficient is high, and the melt is cooled through chute combining. The pure oxygen combustion system is characterized in that natural gas is used as fuel; oxygen is adopted as a combustion-supporting medium; rock wool melt is heated through combustion of pure oxygen combustion guns; the particular positions, acting on the rock wool melt, of the pure oxygen combustion guns are the top part of a siphonal opening, the lower part of a No. 1 movable chute and the lower part of a No. 2 movable chute; the real-time multi-point accuracy control of natural gas or oxygen flow rate is realized through real-time on-line measurement of the multi-point temperatures of the rock wool melt, so that the process temperature needed by the rock wool melt can be accurately controlled. According to the pure oxygen combustion system, stable production of rock wool product with high acidity coefficient can be realized, the fiber forming rate of rock wool melt can be increased, energy consumption in rock wool melt melting process can be effectively lowered, and the shot content of the product can be reduced.

Description

technical field [0001] The invention relates to a pure oxygen combustion system for multi-point precise control of rock wool melt temperature, in particular to the field of building insulation materials, in particular to a pure oxygen combustion equipment and a multi-point precise control of rock wool melt temperature technology. Background technique [0002] In the rock wool production process, the melting process determines key parameters such as the chemical composition, melt temperature, and melt viscosity of the rock wool melt. These parameters directly affect performance indicators such as acidity coefficient and slag ball content of rock wool fiber. At present, the cupola method is commonly used in the rock wool industry to melt raw materials to obtain rock wool melt. In this method, a large amount of heat energy released by the combustion reaction of coke in the cupola melts the mixed ore raw materials. After the ore raw material is melted, the melt enters two set...
