Abstract
Description
Technical Field
[0001] This utility model relates to the field of insulation technology for water seal supports of annular furnaces, specifically to an insulation structure for a water seal support of annular furnaces. Background Technology
[0002] The temperature of the steel structure around the water seal of the annular furnace exceeds 400℃. The traditional method of heat preservation for the steel structure of the water seal support of the annular furnace is to apply refractory material to the support. Due to the high humidity at the water seal location, the refractory material will gradually fall off after six months of normal use, which can easily cause sludge blockage in the water seal. Moreover, if the heat preservation and insulation are not tight or scientific, the heat loss will be significant.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a water seal support insulation structure for annular furnaces. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a heat preservation structure for a water seal support of an annular furnace.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat preservation structure for a ring furnace water seal support, comprising a heat preservation fiber blanket, wherein the heat preservation fiber blanket is attached to the ring furnace water seal support.
[0006] Furthermore, a pressure plate is attached to the side of the insulation fiber blanket facing away from the ring furnace water seal support. Bolts are provided on the outside of the pressure plate, and the bolts pass through the pressure plate and the insulation fiber blanket to connect with the ring furnace water seal support.
[0007] Furthermore, the annular furnace water seal support includes an outer ring water seal support and an inner ring water seal support, and the heat insulation fiber blanket is attached to the outer ring water seal support and the inner ring water seal support respectively by bolts and pressure plates.
[0008] Furthermore, the spacing between the bolts used to fix the thermal insulation fiber blanket on the outer ring water seal bracket is 400mm.
[0009] Furthermore, the spacing between the bolts used to fix the thermal insulation fiber blanket on the inner ring water seal bracket is 300mm.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model redesigns the insulation method of the water seal support, uses a new type of insulation fiber blanket, and innovates the installation method: the fiber blanket is fixed and compacted using pressure plates and bolts. This installation method ensures that the insulation fiber blanket is tight, not easy to fall off, and easy to replace and maintain. The temperature drop of the steel structure is reduced from 200-250℃ to 100-150℃, and the insulation effect is significantly improved; the gas consumption of the ring furnace is reduced by 0.8-1.3 Nm³. 3 / t, with significant energy-saving effect.
