Abstract
The utility model relates to a heat-treatment furnace waste gas recycling system which can use waste gas and save energy. The air discharging port of the heating area of the heat-treatment furnace is connected with the hot-air channel inlet of a heat exchanger, and the cold-air channel outlet of the heat exchanger is connected with the air absorbing port of the heating area. Hot waste gas which comes out of the air discharging port exchanges heat in the heat exchanger with air which is absorbed into the air absorbing port. Air is heated, and heated air enters the heating area from the air absorbing port. Air with certain temperature is heated by a burning system, so fuel is saved.
Description
Technology neck city
The utility model relates to heat-treatment furnace exhaust gas utilization system, especially the automobile exhaust gas utilization system of wheel hub heat-treatment furnace.
Background technology
Heat-treatment furnace generally has a thermal treatment zone, and the heat-treatment furnace that has has two thermals treatment zone of high and low temperature, as automobile wheel hub heat-treatment furnace, just comprises solid solution stove, two thermals treatment zone of aging furnace, and the temperature of solid solution stove heating is about 540 ℃, belongs to the high temperature thermal treatment zone.The temperature of aging furnace heating is about 155 ℃, belongs to the low-temperature heat district.Generally there is combustion system the thermal treatment zone, during fan running in the air channel, from the inlet scoop suck air, is blown into the operating room of the thermal treatment zone after the combustion system heating, after material is heated, is back to fan again.Part waste gas is discharged through exhaust outlet.
We know that the waste gas of discharging from the thermal treatment zone has uniform temperature, do not utilize and directly discharging, cause certain waste.
Summary of the invention
What the utility model solved is the problem that existing heat-treatment furnace waste gas directly discharges, utilizes, and provides a kind of exhaust gas utilization, with the heat-treatment furnace of energy savings.
The waste gas circulation of this heat-treatment furnace is utilized system, is the hot-air channel import that the exhaust outlet of the heat-treatment furnace thermal treatment zone is connect heat exchanger, and the cold air duct outlet of heat exchanger connects the inlet scoop of the thermal treatment zone.
The hot waste gas that comes out from exhaust outlet carries out heat exchange with the air that is about to be inhaled into the inlet scoop in heat exchanger, air is heated, air after the heating enters the thermal treatment zone from the inlet scoop again, and combustion system can heat the air that uniform temperature is arranged, and has saved fuel.
To the heat-treatment furnace of two thermals treatment zone of high low temperature is arranged, as further improvement, the exhaust outlet of its high temperature thermal treatment zone connects the hot-air channel import of heat exchanger, and the cold air duct outlet of heat exchanger connects the inlet scoop of the high temperature thermal treatment zone; The inlet scoop in low-temperature heat district and high temperature thermal treatment zone exhaust outlet communicate with pipeline between the hot-air channel import.The waste gas part of the high temperature thermal treatment zone not only heats the air that enters the high temperature thermal treatment zone like this, and its another part also directly enters the inlet scoop in low-temperature heat district.Because the low-temperature heat district is relatively low to the required temperature of material heating, so the combustion system in the low-temperature heat district can meet the demands to the fuel heating that the gas that uniform temperature is arranged of coming in from its inlet scoop only need burn less.Like this, just saved the energy greatly.
Description of drawings
Fig. 1 is that automobile utilizes system construction drawing with the waste gas circulation of wheel hub heat-treatment furnace.
Among the figure, 21 solid solution stoves; 22 aging furnaces; 23 solid solution fire grate pipes; 24 heat exchangers; 25 combustion fans; 26 bypass pipes; 27 blast pipes; 28 air-introduced machines; 33 motor-driven valves; 34 combustion-supporting airducts; 35 hand-operated valves.
The specific embodiment
Utilize system below in conjunction with the description of drawings automobile with wheel hub heat-treatment furnace waste gas circulation.
The exhaust outlet of solid solution stove 21 connects the hot-air channel import of heat exchanger 24 through solid solution fire grate pipe 23, and the hot-air channel outlet of heat exchanger 24 connects air-introduced machine 28.The cold air duct outlet of heat exchanger 24 connects the inlet scoop of solid solution stove through combustion-supporting airduct 34; The cold air duct import of heat exchanger 24 connects combustion fan 25.The inlet scoop of aging furnace 22 connects solid solution fire grate pipe 23 by bypass pipe 26.
The hot waste gas that solid solution stove combustion chambers burn produces is diverted to bypass pipe 26 through solid solution fire grate pipe 23 and is sucked by the aging furnace internal fan for about 520 ℃.The unnecessary waste gas of aging furnace is limited the quantity of and is incorporated the suction inlet of air-introduced machine 28 into from blast pipe 27 and through being connected hand-operated valve 35 on the blast pipe 27.Solid solution stove combustion chambers burn produces unnecessary waste gas and regulates discharge amount of exhaust gas by the motor-driven valve 33 that is connected on the solid solution fire grate pipe 23, carry out reverse cold and hot exchange through heat exchanger 24 and the air that combustion fan 25 produces, the combustion air after being preheated is entered in the combustion system of solid solution stove by combustion-supporting airduct 34.Discharge outdoor through the waste gas that heat exchanger 24 is discharged by air-introduced machine 28.
The waste gas that solid solution stove burning heating (540 ℃) is produced flows to aging furnace (155 ℃) and utilizes, the waste gas (about 150 ℃) that goes out when the timeliness fire grate is once more through the combustion air reverse heat-exchange of over-heat-exchanger with burning usefulness, about 30 ℃ of combustion-supporting wind-warm syndrome can be improved, the effect that waste heat utilizes again can be reached.By waste heat recovery, the technology that the hot waste gas secondary utilizes has again obviously embodied energy-saving effect.
