Abstract
The utility model relates to a tempering furnace with a flue gas recovery and combustion characteristic, and belongs to the field of heat treatment. The tempering furnace comprises a furnace body, wherein a fire-resistant insulating layer is arranged on the inner wall of the furnace body, a conveying chain for conveying workpieces is arranged in the furnace body, a flow deflector is arranged on the top wall of the furnace body, the flow deflector and the top wall of the furnace body form a flue gas conveying channel, a fan is arranged at the top of the furnace body close to a furnace inlet, a flue gas suction inlet is formed in the flow deflector in a position corresponding to the fan, a flue gas outlet is formed between the flow deflector and the top wall of the furnace body and faces the inside of the furnace body, and a combustion nozzle is arranged in the flue gas conveying channel. The tempering furnace is safe, environment-friendly and low in cost.
Description
Technical field
The utility model relates to a kind of off-gas recovery burning tempering stove, belongs to Field of Heat-treatment.
Background technology
Workpiece through oily medium quenching, its surface adhesion has a large amount of quenching oils, when carrying out tempering subsequently, because the Heating temperature in tempering stove is not enough to reach the temperature of combustion of quenching oil, so workpiece enters burner hearth when heating, the quenching oil of the surface adhesion fast vaporizing that is heated, produces a large amount of flue gases, atmospheric environment is polluted, and endanger workers ' health.
For head it off, existing technological method mainly contains following 2 kinds:
1, cleaning machine is set before tempering stove, the quenching oil that is attached to workpiece surface is washed.Although eliminated oily medium, enter tempering stove and then avoid producing flue gas, cleaning machine involves great expense, and scavenging solution consumption and follow-up sewage disposal, bring very high working cost.
2, before tempering stove, set up smoke gas collecting apparatus, smog is introduced in special filtration unit (fly-ash separator), oil mist particles is adsorbed.But this filtration unit easily stops up, work-ing life is shorter, and there is inflammable and explosive potential safety hazard.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: the off-gas recovery burning tempering stove that a kind of safety and environmental protection, cost are low is provided.
Off-gas recovery burning tempering stove described in the utility model, comprise body of heater, on inboard wall of furnace body, establish refractory insulating layer, in body of heater, have the conveyor chain of conveying work pieces, on body of heater roof, establish pod, pod and body of heater roof form flue gas transfer passage, near the body of heater top of burner hearth import establishing blower fan, and establish flue gas suction port on the pod of blower fan correspondence position, between pod and body of heater roof, establish exhanst gas outlet, exhanst gas outlet is inner towards body of heater, in flue gas transfer passage, establishes burner noz(zle).
Principle of work and process:
During work, workpiece enters burner hearth with conveyor chain, along with temperature raises gradually, make the quenching oil of workpiece surface vaporize rapidly and produce a large amount of flue gases, the blower fan at body of heater top sucks flue gas from flue gas suction port, and flows to burner noz(zle) along flue gas transfer passage, utilizes the thermal-flame of nozzle ejection that smoke combustion is fallen, the heat producing is transported in burner hearth from exhanst gas outlet with hot gas flow, is recovered and utilizes heated parts.
The beneficial effect that the utility model compared with prior art had is:
Off-gas recovery burning tempering stove described in the utility model, can directly burn flue gas and the heat producing is recycled, both free from environmental pollution, and has saved the energy, provides cost savings, and has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment schematic diagram.
In figure: 1, conveyor chain; 2, burner hearth import; 3, flue gas suction port; 4, blower fan; 5, flue gas transfer passage; 6, pod; 7, body of heater; 8, burner noz(zle); 9, hot gas flow outlet.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, off-gas recovery burning tempering stove described in the utility model, comprise body of heater 7, on body of heater 7 inwalls, establish refractory insulating layer, in body of heater 7, establish conveyor chain 1, on body of heater 7 roofs, establish pod 6, pod 6 forms flue gas transfer passage 5 with body of heater 7 roofs, blower fan 4 is established at body of heater 7 tops near burner hearth import 2, with on the pod 6 of blower fan 4 correspondence positions, establish flue gas suction port 3, between pod 6 and body of heater 7 roofs, establish hot gas flow outlet 9, hot gas flow outlet 9, towards body of heater 7 inside, is established burner noz(zle) 8 in flue gas transfer passage 5.
Principle of work and process:
During work, workpiece enters body of heater 7 with conveyor chain 1, high temperature makes the quenching oil of workpiece surface vaporize rapidly and produce a large amount of flue gases, blower fan 4 work, by flue gas from 3 suction of flue gas suction port, and flow to burner noz(zle) 8 along flue gas transfer passage 5, and burner noz(zle) 8 falls smoke combustion, and the heat of generation turns back in body of heater 7 and is recovered and utilizes heated parts from hot gas flow outlet 9.
