Description
Technical field
The utility model relates to waste heat utilization equipment in the metal smelt process, especially relates to a kind of aluminium bits drying and forewarm device.
Background technology
The development of Energy Saving for Industrial Furnace technology has been passed through used heat and has not been utilized two stages that begin to utilize with used heat, aluminium industry smelting furnace smelting furnace like this equally, the most original, and the stove exit gas is taken away a large amount of heat energy, and the thermal efficiency of stove is below 30%.Through development, producer adopts in flue the device that reclaims hot flue gas to come heat in the recovered flue gas at large, reached certain energy-saving effect, but still exist such as reclaim that heat is limited, the air preheater life-span is short and burner hearth in have the local problems such as high-temperature region.At present, Regenerative Combustion Technology is generally promoted on stove, and Regenerative Combustion Technology is to use the regenerator heat exchange principle, reaches the recovery of flame furnace waste gas residual heat, combustion air and gas-preheating, thus the decrease fuel consumption.Use Regenerative Combustion Technology in line attached flue need to be set, although most fume afterheat is utilized in the smelting furnace, still have 35% flue gas directly to drain by attached flue, can't be utilized.Reclaim smelting furnace as example take aluminium bits, owing to containing a large amount of moisture in the aluminium that the reclaims bits, need through just melting down melting after the dry kiln heating, heating process need to consume a large amount of fuel, remains simultaneously 35% fume afterheat and still can't be fully used.
The utility model content
The purpose of this utility model provides a kind of aluminium bits drying and forewarm device, can improve the utilization rate of waste heat in the aluminum smelting technology process, energy-conserving and environment-protective.
For achieving the above object, the utility model provides a kind of aluminium bits drying and forewarm device, comprise aluminium bits smelting furnace and aluminium bits oven dry rotary kiln, described aluminium is considered smelting furnace to be worth doing and is connected aluminium bits oven dry rotary kiln by connecting the flue connection, and described connection flue is provided with motor-operated control valve.
Preferably, described aluminium bits oven dry rotary kiln is provided with smoke inlet, exhanst gas outlet, aluminium bits entrance and the outlet of aluminium bits.
Therefore, the utility model employing said structure, the utilization rate of waste heat in the aluminum smelting technology process can be improved, energy-conserving and environment-protective.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the utility model aluminium bits drying and forewarm device embodiment.
The specific embodiment
Embodiment
Fig. 1 is the structural representation of the utility model aluminium bits drying and forewarm device embodiment, as shown in Figure 1, comprise aluminium bits smelting furnace 1 and aluminium bits oven dry rotary kiln 5, aluminium bits smelting furnace 1 is connected oven dry rotary kiln 5 to be worth doing and is connected by connecting flue 2 with aluminium, connect flue 2 and be provided with motor-operated control valve 3.Aluminium bits oven dry rotary kiln 5 is provided with smoke inlet 4, exhanst gas outlet 6, the outlet 7 of aluminium bits and aluminium bits entrance 8.Connection flue 2 is fixed in smoke inlet 4 places on the aluminium bits oven dry rotary kiln 5.Connect flue 2 and be communicated with aluminium bits smelting furnace 1 and aluminium bits oven dry rotary kiln 5, connect the motor-operated control valve 3 that arranges on the flue 2, aluminium bits oven dry rotary kiln 5 by stentplacement in certain height, make things convenient for its operation, smoke inlet 4 and aluminium bits outlet 7 ends that are arranged at, exhanst gas outlet 6 and the import 8 of aluminium bits are arranged at the other end of aluminium bits oven dry rotary kiln 5, and one goes out one advances to interact.
The aluminium bits enter aluminium bits oven dry rotary kiln 5 from aluminium bits entrance 8, and aluminium bits oven dry rotary kiln 5 makes things convenient for the aluminium bits to glide from 5 rotations of aluminium bits oven dry rotary kiln towards the downward-sloping certain angle of aluminium bits smelting furnace 1 direction.When aluminium bits enter aluminium bits oven dry rotary kiln 5, the flue gas of aluminium bits smelting furnace 1 is from the 1 interior discharge of aluminium bits smelting furnace, enter aluminium bits oven dry rotary kiln 5 by connecting flue 2, form opposite trend with the aluminium bits, thereby preheating enters the aluminium bits of aluminium bits oven dry rotary kiln 5, by being provided with motor-operated control valve 3 connecting flue 2, control from aluminium bits smelting furnace 1 according to the size of the temperature of aluminium bits preheating and the amount of needing an extension and to enter exhaust gas volumn in the aluminium bits oven dry rotary kiln 5, prevent that aluminium from considering overheated scaling loss to be worth doing.Preheated aluminium bits enter aluminium bits smelting furnace 1 from aluminium bits oven dry rotary kiln 5 and carry out melting, and the flue gas of considering cooling by aluminium to be worth doing is that exhanst gas outlet 6 is discharged from smoke discharging pipe, considers the purpose of heat recovery to be worth doing thereby reach the residual heat drying aluminium that utilizes useless flue gas.
In the present embodiment, enter for the aluminium bits oven dry rotary kiln of drying the aluminium bits from the subsidiary pipeline of aluminium bits smelting furnace flue gas out by body of heater, adopt rotation formula, the aluminium bits are along with the ceaselessly up and down rolling of rotation of aluminium bits oven dry rotary kiln, after flue gas enters aluminium bits oven dry rotary kiln, aluminium bits preheating with rolling, reach the temperature requirement that melts down melting, the present embodiment does not need consume fuel, directly utilize the moisture that contains in the residual heat drying aluminium bits in the flue gas, effectively utilized fume afterheat, reduce final temperature of discharging flue gas, reach emission request, energy-conserving and environment-protective.Therefore, the utility model employing said structure, the utilization rate of waste heat in the aluminum smelting technology process can be improved.
It should be noted that at last: above embodiment is only in order to the technical solution of the utility model to be described but not limit it, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
