Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model embodiment provides a kind of aluminum-bar heating furnace, comprises body of heater 1, firelock 2, combustion fan 3, circulating fan 4 and blast pipe 5.Described firelock 2 can be fuel oil firelock or combustion gas firelock, and it is located at body of heater 1 side, for heating for the aluminium bar in body of heater 1.Described combustion fan 3 is connected with firelock 2, for providing combustion air for firelock 2.Body of heater 1 top is vertically located at by described blast pipe 5, with body of heater 1 inner space, for discharging the waste gas after burning.Be provided with heat-exchange device 6 in described blast pipe 5, described heat-exchange device 6 comprises the heat exchange chamber 61 be located in blast pipe 5, and described heat exchange chamber about 61 two ends are communicated with blast pipe 5, and two ends, left and right are communicated with circulating fan 4 and the combustion-supporting airduct 7 of pair.Described circulating fan 4 is by heat-exchange device 6 described in extraneous air suction, described heat-exchange device 6 carries out heat exchange for the extraneous air of the hot-air of being discharged by blast pipe 5 and circulating fan 4 suction, extraneous air after intensification is converged by the combustion-supporting airduct of described pair 7 and main combustion-supporting airduct 8, pressurize via combustion fan 3, for firelock 2 provides combustion air.
The heat exchange principle of the present embodiment is: the waste gas in body of heater 1 is discharged straight up via blast pipe 5, the extraneous air of circulating fan 4 suction laterally passes into the heat exchange chamber 61 in blast pipe 5, in heat exchange chamber 61, the staggered flowing of air of waste gas and suction, contact with each other and carry out heat exchange, because the blast of circulating fan 4 is much larger than the blast of blast pipe 5, therefore can ensure that the air of most of suction enters into combustion fan 3 by secondary combustion-supporting airduct 7 after carrying out heat exchange.
Combustion air, by being provided with heat-exchange device 6 in blast pipe 5, is heated by the waste gas of blast pipe 5 by the utility model in advance, reduces the heat loss in body of heater 1, saves the energy; Above-mentioned heat-exchange device 6 is rational in infrastructure, and working stability is reliable, and it is convenient to safeguard, contributes to reducing enterprise operation cost.
Preferably, described heat-exchange device 6 also comprises the heat exchanger plates 62 be located in heat exchange chamber 61, and described heat exchanger plates 62 is provided with through hole 621, and described heat exchanger plates 62 in parallel to each other level is located in described heat exchange chamber 61.
It should be noted that the setting of heat exchanger plates 62 strengthens the heat exchange efficiency of heat-exchange device 6, also make the flowing of the air of waste gas and suction more reasonable.Specifically, the waste gas risen in blast pipe 5 contacts with horizontally disposed heat exchanger plates 62, and waste gas is upwards discharged via the through hole 621 of heat exchanger plates 62 and side continuation, and the heat in waste gas is delivered on heat exchanger plates 62.The air of circulating fan 4 suction passes through between the described heat exchanger plates 62 be parallel to each other, and its obstruction being subject to heat exchanger plates 62 is less, also can enter secondary combustion-supporting airduct 7 at a relatively high speed after therefore absorbing the heat of heat exchanger plates 62.Take into account economy and heat conductivility, described heat exchanger plates 62 can be steel plate or corrosion resistant plate.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
