Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical silicon furnaces, and in particular relates to a smoke hood device without a central skeleton beam. Background Art

[0002] Industrial silicon furnaces are needed in the processing and production process of the metallurgical industry, and the smoke hood is one of the indispensable parts of the industrial silicon furnace. Under normal circumstances, the water-cooled cover plate at the center of the top of the smoke hood is supported and suspended by a water-cooled skeleton beam. After long-term use, the flue gas temperature at the top of the center part of the smoke hood changes unpredictably, ranging from 30℃ to 850℃, causing the water-cooled skeleton beam in the center to expand and contract due to heat, especially the 90° connected welds, which are prone to cracking and causing water leakage. For this reason, we propose a smoke hood device without a center skeleton beam. Utility Model Content
