Description
Technical field:
The utility model relates to the rotary heating furnace applied technical field, is that a kind of annular furnace waste heat efficiently utilizes system specifically.
Background technology:
Rotary heating furnace is large-scale Thermal Equipment, be mainly used in the heating of round members such as pipe, its fuel combustion mode divides two kinds, a kind of is conventional combustion system, by the highly effective air heat exchanger that places in the flue, comes warm-up combustion-supporting air (temperature general≤500 ℃), directly entering burner then can burn while mixing with various fuel, to provide heater block required heat, this mode combustion air preheat temperature is low, and waste heat recovery efficient is low; Another kind is a heat-accumulation combustion, Regenerative Combustion System is mainly by heat-accumulating burner, exchange system, control system, coal gas system, air feed system, compositions such as smoke evacuation system, heat-accumulating burner is made up of burner body and heat storage two parts, heat storage belongs to heat exchange section, air-flue gas distributor box is positioned at the burner rear portion, the timing of finishing air and flue gas under reversal valve cooperates is switched, because this heat transfer type, combustion air can be preheating to more than 1000 ℃, thereby realize the effect of high efficiente callback fume afterheat, but it is on the low side and contain reasons such as tar impurity owing to hot dirty gas pressure, be not easy to keep the unblocked of regenerator, thereby Regenerative Combustion System was lost efficacy, can only realize the preheating of combustion air list; But hot dirty gas produces mixed gas by air-low-pressure steam gasification, it contains a large amount of nitrogen, in combustion process, does not participate in combustion reaction, but participate in heat exchange and volumetric expansion, calculate according to burning, the heat-accumulation combustion mode still has a large amount of high temperature airs (accounting for 40%) to drain from flue except that preheated air, so just cause the waste of energy, as adopt waste heat boiler to reclaim, and not only cause the human and material resources waste, inevitably produce a large amount of low-pressure steams simultaneously again.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and provide a kind of annular furnace waste heat efficiently to utilize system, be a kind of with routine burning and heat-accumulation combustion dual mode and the novel heat exchange method deposited, problem such as the combustion air preheat temperature is low when mainly solving existing rotary heating furnace and adopting hot dirty gas to burn, waste heat recovery efficient is low.
In order to reach above-mentioned order, the utility model is achieved in that a kind of annular furnace waste heat efficiently utilizes system, it comprises the smokejack 2 that is installed on the annular body of heater 10, the end of smokejack 2 is connected with chimney 1, its special character is to establish many group heat-accumulating burners 11 and heat-accumulating burner 12 on annular body of heater 10, in smokejack 2, establish heat exchanger, heat exchanger cold wind mouth 3 and exchanger heat air port 4 are arranged on the heat exchanger, heat exchanger cold wind mouth 3 is connected with blower fan 8 by pipeline, exchanger heat air port 4 is by pipeline and exchange system 7, heat-accumulating burner 11, heat-accumulating burner 12 connects, exchange system 7 is connected with smokejack 2 by smoke evacuation pipeline 9, exchange system 7 is connected with heat-accumulating burner 12 with heat-accumulating burner 11 by pipeline, afterbody at heat-accumulating burner 11 and heat-accumulating burner 12 is connected with gaspipe line 6 with gaspipe line 5 respectively, in the exchanger heat air port 4 with heat-accumulating burner 11, establish hot blast butterfly valve 13 on the pipeline that heat-accumulating burner 12 connects.
A kind of annular furnace waste heat described in the utility model efficiently utilizes system compared with the prior art to have following good effect: can realize two kinds of combustion systems of routine-accumulation of heat easily, utilize high-temperature flue gas waste heat and abatement apparatus fault to greatest extent, reduce investment outlay, when a kind of combustion system goes wrong, can adopt another kind of combustion system.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, provide a kind of annular furnace waste heat of specific embodiment detailed description the utility model below in conjunction with accompanying drawing and efficiently utilize system.
Embodiment 1, referring to Fig. 1, fixed installation many groups heat-accumulating burners 11 and 12, one heat-accumulating burners 11 of heat-accumulating burner and a heat-accumulating burner 12 are one group on annular body of heater 10, and the afterbody of heat-accumulating burner 11 and heat-accumulating burner 12 is connected with gaspipe line 6 with gaspipe line 5 respectively; Mounting heat exchanger in smokejack 2 has heat exchanger cold wind mouth 3 and exchanger heat air port 4 on the heat exchanger, smokejack 2 is fixedly mounted on the annular body of heater 10, in the end of smokejack 2 chimney 1 is installed; Heat exchanger cold wind mouth 3 is connected with blower fan 8 by pipeline, exchanger heat air port 4 is connected with exchange system 7, heat-accumulating burner 11,12 by pipeline, exchange system 7 is connected with smokejack 2 by smoke evacuation pipeline 9, exchange system 7 is connected with heat-accumulating burner 12 with heat-accumulating burner 11 by pipeline, heat-accumulating burner 11 and heat-accumulating burner 12 can be shared a cover commutation system, installation hot blast butterfly valve 13 on exchanger heat air port 4 and pipeline that heat-accumulating burner 11,12 is connected.
