Energy-saving float glass furnace

Abstract

The invention provides a furnace, in particular to an energy-saving float glass furnace which comprises a melting zone, a settling zone, a neck and a cooling part which are sequentially communicated, wherein the neck is provided with a deep separation device for molten glass; the deep separation device for the molten glass comprises at least a group of rectangular retaining walls, the two ends of the retaining walls are supported on pool walls at the two sides of the neck, and the bottom surfaces of the retaining walls are positioned between the 1 / 3 position and the 2 / 3 position of the neck in the depth direction from top to bottom; each group of the retaining walls comprise N numbered fire-proof bricks and (N-1)*3 numbered fire-proof pin shafts, N is a natural number greater than or equal to 2, and every two adjacent fire-proof bricks are jointed through three fire-proof pin shafts which are arranged triangularly; the width of the neck is within 2.5m; the width of the cooling part is within 7m; the depth of a pool is 600-1000mm; and the area of the cooling part is less than 15% of the sum of the area of the melting zone and the area of the settling zone. The furnace has the advantage of better energy-saving effect.

Description

technical field [0001] The invention provides a kiln, in particular, an energy-saving float glass kiln. Background technique [0002] At present, the existing float glass furnace includes a melting zone, a clarification zone, a neck and a cooling part connected in sequence, the width of the neck is greater than 3.5 meters, and the area of ​​the cooling part is 25-30% of the combined area of ​​the melting zone and the clarification zone . During the production process, on the one hand, the high-temperature molten glass in the melting zone and clarification zone flows into the cooling part through the neck, and the temperature of the molten glass drops significantly; The neck part flows back into the refining zone and melting zone. Because the kiln has a structure with a wide neck and a large cooling part, and the neck has no corresponding device for deep separation of the glass liquid, this makes the furnace have a large reflux coefficient and high energy consumption. In a...

AI Technical Summary

Problems solved by technology

Because the kiln has a wide neck and a large cooling section, and the neck has no corresponding device for deep separation of the glass liquid, so the furnace has a large reflux coefficient and high energy consumption

In addition, it also makes the contact area between the molten glass and the refractory pool wall of the neck and the cooling part larger, which increases the secondary pollution of the molten glass and easily brings defects to the glass.
