Abstract
Residual heat from flue gas utilizes system including continuous annealing furnace, heat recovery device, pre -heater nozzle, gas - water heat exchanger, combustion air heat exchanger and cleaning section hot air drier, adds at continuous annealing furnace's exhanst gas outlet and is equipped with the dust remover, and heat recovery device is connected to the dust remover, on heat recovery device feeds through pre -heater nozzle, gas - water heat exchanger, combustion air heat exchanger and cleaning section hot air drier respectively, combustion air heat exchanger intercommunication have main nozzle and preheating section after burning nozzle. The utility model discloses the waste heat that go up to produce galvanizing line not only make full use of on other A number of processes that need heat, still with the heat supply of waste heat utilization to the office building, reduces the fume emission temperature to the production line, has reduced and has discharged fume to the thermal pollution of environment, has reached saving energy and increasing the efficiency's purpose.
Description
Technical field
The utility model relates to energy-conserving and environment-protective field, particularly relates to the flue gas heat recovery of zinc-plated industry.
Background technology
Continuous annealing furnace belongs to thermal hardware, each section of continuous annealing furnace composition, preheating section, direct combustion section, radiation pipeline section, cooling section and hot idler roller section, its high-temperature flue gas major part produced just directly has not been discharged effectively to utilize, result in the waste of the energy, thus reduce the heat energy efficiency of stove to a great extent, and exacerbate greenhouse effects and environmental pollution.
Summary of the invention
The utility model, for making full use of high-temperature flue gas, provides a set of flue gas heat recovery system.
The scheme that the utility model is taked:
Flue gas heat recovery system, comprise continuous annealing furnace, heat regenerator, preheater burner, air-water heat exchanger, combustion air heat exchanger and cleaning section hot-air drier, deduster is added at the exhanst gas outlet of continuous annealing furnace, deduster connects heat regenerator, heat regenerator is communicated on preheater burner, air-water heat exchanger, combustion air heat exchanger and cleaning section hot-air drier respectively, and described combustion air heat exchanger is communicated with main burner and preheating section afterburning burner.
Described air-water heat exchanger is undertaken circulating to office building heating plant by heat pump.
The beneficial effects of the utility model: the waste heat that galvanization production line produces not only makes full use of on the multiple working procedure of other needs heating on production line by the utility model, also by the heat supply of UTILIZATION OF VESIDUAL HEAT IN to office building, reduce smog discharge temperature, decrease the thermal pollution of smoke evacuation to environment, reach the object of energy efficiency.
Accompanying drawing explanation
Fig. 1 is the block diagram of this flue gas heat recovery system.
Detailed description of the invention
Flue gas heat recovery system, comprise continuous annealing furnace, heat regenerator, preheater burner, air-water heat exchanger, combustion air heat exchanger and cleaning section hot-air drier, deduster is added at the exhanst gas outlet of continuous annealing furnace, deduster connects heat regenerator, heat regenerator is communicated on preheater burner, air-water heat exchanger, combustion air heat exchanger and cleaning section hot-air drier respectively, and described combustion air heat exchanger is communicated with main burner and preheating section afterburning burner.
The flue gas of the direct combustion heating section of continuous annealing furnace is delivered in heat regenerator after deduster dedusting, flue gas is transported to preheater burner and band steel is preheating to about 200 DEG C by heat regenerator again, flue gas in heat regenerator is then by combustion air heat exchanger heating combustion air about 450 ~ 500 DEG C, supply the main burner combustion of direct combustion heating section and preheating section burner to use, supply simultaneously cleaning section hot-air drier gentle-water-to-water heat exchanger is Office Area heat supply.
