Abstract
The utility model discloses a kind of off-gas recovery reuse means for smelting furnace, it includes burner hearth；The side of burner hearth is equipped with heat exchange box I, heat exchange box II and heat exchange box III；Heat exchange box I, heat exchange box II and heat exchange box III are connected to by burner with burner hearth respectively, and burner is connected to by the gas pipeline with gas valve with fuel cartridge respectively；Heat exchange box I, heat exchange box II and heat exchange box III are connected to main air inlet pipe respectively；The front end of main air inlet pipe is equipped with air blower；Heat exchange box I, heat exchange box II and heat exchange box III are connected to smoke evacuation supervisor respectively；Smoke evacuation supervisor is equipped with throttling smoke pipe, and the smoke pipe that throttles is connected to by throttle valve with main air inlet pipe.Off-gas recovery preheats high-temperature flue gas to the air in main air inlet pipe by throttling smoke pipe, and respectively enters in heat exchange box I, II, III, exchange hot-bulb heating；Throttle valve into main intake stack, reuses 30% to 40% smoke backflow, and section has lacked the dosage of new compressed air, burns and sufficiently decomposes again.
Description
Technical field
The utility model belongs to aluminium ingot melting corollary equipment technical field, and in particular to a kind of cigarette for molten aluminum smelting furnace
Gas recycling and reusing device.
Background technique
In the prior art, smelting furnace can generate high-temperature flue gas in melting molten aluminum, and traditional fume treatment mode is to pass through
Flue gas is introduced purification device by pipeline, is discharged again after purification.
In the specific use process, insufficient, imperfect combustion flue gas warp of the flue gas in smelting furnace due to burning
Crossing purification will increase subsequent processing load, meanwhile, the air injected into smelting furnace is also required to by preheating to reduce temperature
Difference improves efficiency of combustion.
Therefore, how the flue gas in smelting furnace to be recycled again, the purification efficiency of Lai Tigao flue gas simultaneously can also be right
Air carries out preheating and improves efficiency of combustion, is a problem urgently to be solved.
Summary of the invention
The purpose of this utility model is that the solution prior art is difficult to control there are molten aluminum flow and unhandy technology is asked
Topic, provides a kind of off-gas recovery reuse means for smelting furnace, with overcome the deficiencies in the prior art.
To achieve the goals above, a kind of off-gas recovery reuse means for smelting furnace of the utility model, it includes
Burner hearth；
The side of the burner hearth is equipped with heat exchange box I, heat exchange box II and heat exchange box III；It the heat exchange box I, heat exchange box II and changes
Hot tank III is interconnected by burner and burner hearth respectively, and burner passes through gas pipeline with gas valve and combustion gas respectively
Tank is interconnected；
The heat exchange box I, heat exchange box II and heat exchange box III pass through blast pipe and main air inlet pipe phase with air valve respectively
It is intercommunicated；The front end of the main air inlet pipe is equipped with air blower；The heat exchange box I, heat exchange box II and heat exchange box III pass through band respectively
The fume pipe and smoke evacuation supervisor for having exhaust smoke valve are interconnected；Its main points is that the smoke evacuation supervisor is equipped with the section interconnected with it
Smoke pipe is flowed, and the smoke pipe that throttles is interconnected by throttle valve and main air inlet pipe.
The utility model is structurally reasonable, and the off-gas recovery in smoke evacuation supervisor can be made high-temperature flue gas to master by throttling smoke pipe
Air in air inlet pipe is preheated, and is finally respectively enterd in heat exchange box I, heat exchange box II and heat exchange box III, so as to heat exchanging
Ball is heated；Throttle valve into main intake stack, reuses 30% to 40% smoke backflow；Off-gas recovery utilizes, section
The dosage of new compressed air is lacked；The harmful substance in flue gas is sufficiently decomposed through burning again simultaneously, reduces subsequent environmental protection
The operational pressure of facility.
Advantage: 1, two aspect of energy conservation: 1) flue gas waste heat part itself re-uses, 2) thermal energy of smoke combustion passes through accumulation of heat
Case accumulation of heat re-uses, and reaches energy conservation.
2, flue gas repeated combustion reaches clean-burning, reduces discharge of poisonous waste.
