Abstract
The utility model discloses a compound furnace wall for a vertical volatilization furnace. The compound furnace wall comprises a furnace body (1) and a furnace wall (2), wherein the outmost layer of the furnace wall (2) is a thermal-protective layer (3), the innermost layer of the furnace wall is a fireproof layer (4), and a thermal insulation layer (5) is arranged between the thermal-protective layer (3) and the fireproof layer (4). The compound furnace wall for the vertical volatilization furnace can effectively reduce surface temperature of the furnace body, reduces heat loss of the furnace wall, and is good in thermal insulation performance and high in thermal utilization rate.
Description
Technical field
The utility model relates to the antimony ore field of smelting, relates to a kind of compound furnace wall that is used for the vertical volatilization stove of antimony oxygen powder pyrogenic method smelting specifically.
Background technology
Antimony oxygen powder mainly is that antimony ore passes through in volatilization roasting equipment, behind the volatilization roasting, to utilize the volatile characteristic of Sb2O3 to produce.At present, be used for the volatilization roasting equipment that antimony oxygen powder pyrogenic method smelts and mainly contain He Shi stove, open hearth, straight well stove, rotary kiln, blast furnace and cyclone furnaces etc.All there is a problem in existing pyrometallurgical smelting stove, is exactly that furnace wall structure is single, and general is to be built by laying bricks or stones or poured into a mould by refractory brick to form; It is heat insulation, heat insulation effect is bad; Furnace wall cylinder body outer wall temperature is far above the temperature of external environment, and radiation loss is big, causes energy consumption bigger.
Summary of the invention
To the above-mentioned deficiency that prior art exists, the purpose of the utility model provides a kind of heat insulation, high insulating effect, the compound furnace wall of the vertical volatilization stove that radiation loss is little, heat utilization efficiency is high, save energy and reduce the cost.
The purpose of the utility model realizes through following technical proposals: a kind of compound furnace wall of vertical volatilization stove, comprise body of heater, furnace wall, and said furnace wall outermost layer is a thermal insulation layer, innermost layer is a flame retardant coating, between described thermal insulation layer and flame retardant coating, also is provided with heat-insulation layer.
The thickness of the flame retardant coating of the said furnace wall of the utility model is 25 cm, and the thickness of heat-insulation layer is 20 cm, and the thickness of thermal insulation layer is 5 cm.
Compared with prior art; The useful technique effect of the utility model is: owing to adopt innermost layer is that flame retardant coating, outermost layer are after thermal insulation layer, intermediate layer are the lamination layer structure of heat-insulation layer; Can reduce the body of heater surface temperature effectively, reduce the furnace wall radiation loss; Heat insulation, the good heat insulating of furnace wall, heat utilization efficiency is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1-body of heater 2-furnace wall 3-thermal insulation layer 4-flame retardant coating 5-heat-insulation layer.
The specific embodiment
In conjunction with Fig. 1, the compound furnace wall of the described a kind of vertical volatilization stove of the utility model comprises body of heater 1, furnace wall 2, and the innermost layer of furnace wall 2 is a flame retardant coating 4, and outermost layer is a thermal insulation layer 3, and 3 of flame retardant coating 4 and thermal insulation layers are provided with heat-insulation layer 5.With the compound furnace wall of 50cm is example, and the thickness of flame retardant coating 4 is 25cm, and the thickness of heat-insulation layer 5 is 20cm, and the thickness of thermal insulation layer 3 is 5cm.Flame retardant coating 4 by high temperature resistant, energy-saving phosphate-combined high-aluminium brick build or pour into a mould form, select energy-saving refractory material for use, can reduce body of heater surface temperature, housing radiation loss effectively, make vertical volatilization stove hear rate decline l5-25%.Thermal insulation layer 3 adopts no asbestos calcium silicate board with microporous as heat-barrier material; This material is to be raw material with siliceous material and lime; Through the synthetic a kind of high efficiency heat insulation material of dynamic hydro-thermal, its thermal conductivity factor is lower than 0.22W/ (m. ℃), can effectively reduce the heat loss on body of heater surface; Make uniformity of temperature profile on the body of heater cross section, the volatilization roasting of favourable vertical volatilization stove.The haydite pours that heat-insulation layer 5 adopts the heat build-up stable performance helps keeping the temperature of furnace high-temperature fusion as insulation material, makes heat utilization efficiency higher.After adopting the furnace wall lamination layer structure, make that furnace wall cylinder body outer wall and environment temperature are basic identical, the loss of furnace wall surface radiating is little, helps the formation of high furnace temperature, and comprehensive coal consumption reduces 10-15%.
Claims (2)
1. the compound furnace wall of a vertical volatilization stove; Comprise body of heater (1), furnace wall (2); It is characterized in that: said furnace wall (2) outermost layer is thermal insulation layer (3), and innermost layer is flame retardant coating (4), between described thermal insulation layer (3) and flame retardant coating (4), also is provided with heat-insulation layer (5).
2. the compound furnace wall of a kind of vertical volatilization stove according to claim 1 is characterized in that: the thickness of flame retardant coating (4) is 20cm, and the thickness of heat-insulation layer (5) is 25cm, and the thickness of thermal insulation layer (3) is 5cm.
