Abstract
The utility model provides an energy-saving light flue of a metallurgical furnace, which consists of connecting flanges, an inner casing pipe and an outer casing pipe, wherein the inner casing pipe and the outer casing pipe are in a concentric spiral tube structure, a cavity is arranged between inner casing pipe and the outer casing pipe, and connecting flanges are fixed at both ends; the inner casing pipe is provided with an expansion joint at joint of the flanges; the inner casing pipe is a flue, and the cavity is a combustion air channel; the bottom of the outer casing pipe of a flue gas outlet is provided with a combustion air inlet, and the top of the outer casing pipe at the point of a flue gas inlet is provided with a combustion air outlet; and the upper parts of the inner casing pipe and the outer casing pipe are provided with a plurality of explosion-proof holes, the lower parts of the inner casing pipe and the outer casing pipe are provided with a plurality of deashing mouths, and the inner casing pipe and the outer casing pipe are both made of heat-resistant materials. The utility model has the advantages of saving the cost, increasing the work efficiency, saving the space and the like.
Description
Technical field
The utility model belongs to the nonferrous metallurgy field, includes a kind of device of conveying of non-ferrous metal flue gas during smelting and heat utilization.
Background technology
The brick flues that the flue gas conveying great majority of nonferrous smelting all adopt refractory brick to build by laying bricks or stones, it is big to take up room, and the support load is big, and foundation of civil work is also big, the inner easy bonding cigarette ash of flue, and the cigarette ash cleaning is very difficult, must take flue apart and could clear up.The heat of flue gas can't utilize, and also needs cooling by the flue gas behind the brick flue before advancing bag collection, and cooling measure has: 1. adopt air-cooled surface-cooler; 2. adopt the cooler of trickle cooling; 3. adopt heat pipe evaporator etc.1. and 2. measure is more traditional cooling measure, and cooling-down effect is apparent in view, shortcoming be exactly waste heat recovery not, and 2. measure also be easy to generate diluted acid corrosion cooler, so cooler needs anticorrosion, high temperature resistant; 3. measure is in recent years in coloured industry technology on probation, the effect at use initial stage is fine, because the dust viscosity ratio of flue gas during smelting is bigger, after using a period of time, adhere to a large amount of dusts on the tubulation, the fin heat exchange pipe adhering speed is not faster, and the heat exchange effect sharply descends, as last just as an exhaust gases passes.Shandong factory has adopted heat pipe evaporator, and the use initial stage per hour produces 4 tons of steam, after 3 months, per hour can only produce 1 ton of steam, after 6 months, per hour can only produce 0.03 ton of steam, at last just as an exhaust gases passes.
Summary of the invention
The purpose of this utility model is to reach problems such as waste heat recovery weak effect greatly at the existing device heaviness of above-mentioned brick flue, floor space, and a kind of promptly in light weight, the occupation of land of invention design are lacked, and can reclaim the energy-conservation light body flue of metallurgical furnace of part heat in the flue gas again.
The technical scheme that the utility model adopted is: the energy-conservation light body flue of metallurgical furnace, form by adpting flange, inner sleeve, outer tube, inner sleeve, outer tube are concentric spiral tube structure, between cavity is arranged, the fixedly connected flange in two ends; Design has expansion joint to inner sleeve at the adpting flange place; Inner sleeve is a flue, and cavity is a combustion air channel; The outer sleeve bottom of exhanst gas outlet is provided with the combustion air inlet, and the outer tube top at smoke inlet place is provided with the combustion air outlet; The top of inner sleeve, outer tube is provided with some explosionproof holes, and the bottom is provided with a plurality of cleaning doors.Internal and external casing all selects for use temperature-resistant material to make.
Compared with prior art, the utility model has the advantages that: more original device has the basis carrying and alleviates 35%; Support is saved steel 26%; Deashing is convenient and swift; Save space 33%; Effects such as fuel saving 7.5%.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, combustion air outlet, 2 is expansion joint, and 3 is cavity, and 4 is explosionproof hole, and 5 is outer tube, and 6 is inner sleeve, and 7 is adpting flange, and 8 is cleaning door, 9 are the combustion air inlet.
Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.
The specific embodiment
The energy-conservation light body flue of metallurgical furnace is made up of adpting flange 7, inner sleeve 6, outer tube 5, and inner sleeve 6, outer tube 5 are concentric spiral tube structure, between cavity 3 is arranged, the fixedly connected flange 7 in two ends adopts adpting flange 7 between the tube and tube; Design has expansion joint 2 to inner sleeve 6 at adpting flange 7 places, solves the contraction and the expansion issues of inner sleeve 6; Inner sleeve 6 is a flue, and cavity 3 is a combustion air channel; Outer tube 5 bottoms of smoke outlet are provided with combustion air inlet 9, and outer tube 5 tops at smoke inlet place are provided with combustion air outlet 1, and burning wind is by inner sleeve 6 heating, fuel saving; The top of inner sleeve 6, outer tube 5 is provided with some explosionproof holes 4, and the bottom is provided with a plurality of cleaning doors 8.Inside and outside sleeve pipe 6 and 5 all selects for use temperature-resistant material to make.
Claims (2)
1. the energy-conservation light body flue of metallurgical furnace is made up of adpting flange, inner sleeve, outer tube, it is characterized in that inner sleeve, outer tube are concentric spiral tube structure, between cavity is arranged, the fixedly connected flange in two ends; Inner sleeve has expansion joint in the flange connections design; Inner sleeve is a flue, and cavity is a combustion air channel; The outer sleeve bottom of exhanst gas outlet is provided with the combustion air inlet, and the outer tube top at smoke inlet place is provided with the combustion air outlet; The top of inner sleeve, outer tube is provided with some explosionproof holes, and the bottom is provided with a plurality of cleaning doors.
