Description
Technical field
The utility model relates to a kind of heat-treatment furnace, relates to a kind of side smoke evacuation particularly, and the body of heater lower end is provided with the side smoke evacuation underlying heat exchanger type heat-treatment furnace of heat exchanger.
Background technology
At metal annealing, quenching or tempering process, metal forging heating process and metal surface hot melt treatment process all need heat-treatment furnace to produce heat, process.The problem that existing heat-treatment furnace exists is: 1. structure is outmoded, there is not heat-exchange system, flue gas in the body of heater adopts the mode of top smoke evacuation or bottom smoke evacuation, directly enter in atmosphere through discharge flue the flue gas of higher temperature, because the flue-gas temperature height in the body of heater so not only wastes energy, and because the flue-gas temperature height, its nitride and sulfide content height pollute atmospheric environment.2. existing industrial furnace, by artificial thermometric, thermometric is inaccurate, and uncontrollable furnace pressure.
Summary of the invention
The purpose of this utility model provides a kind of energy savings, protection environment, heat exchange efficiency height, the side smoke evacuation underlying heat exchanger type heat-treatment furnace of controllable temperature and pressure.
The utility model is realized by the following technical solutions: side smoke evacuation underlying heat exchanger type heat-treatment furnace, comprise body of heater, it is characterized in that: the side wall of furnace interlayer is provided with exhaust gases passes, exhaust gases passes communicates with the smoke-collecting apparatus that is located at the body of heater lower end, heat exchanger is made of the heat exchanger tube and the heat exchanging chamber that connect, smoke-collecting apparatus communicates with an end of heat exchanger tube, the other end of heat exchanger tube communicates with discharge flue, be provided with gas fume valve in the discharge flue, blower and pipeline communicates with heat exchanging chamber, heat exchanging chamber communicates with the combustion air pipeline, the combustion air pipeline is connected with burner, one end of burner passes the inner chamber that body of heater stretches into body of heater, and body of heater is provided with some temperature sensors and pressure sensor.
The beneficial effects of the utility model are: 1. energy savings, protection environment.The smoke evacuation of employing sidewall, flue gas flows in the smoke-collecting apparatus of body of heater bottom by the exhaust gases passes of sidewall of the furnace body interlayer.High-temperature flue gas enters in the heat exchanger tube of heat exchanger, by blower fan the air of cleaning is sent in the heat exchanging chamber simultaneously, cold air and heat exchanger tube carry out heat exchange, heat exchanger is with cooling high-temperature fume like this, simultaneously the high temperature pure air that gains is sent into burner and send into system again as combustion air, with heat recycling, energy savings.Thereby the high-temperature flue gas that meanwhile reduces temperature has reduced the synthetic of nitride and sulfide owing to temperature is lower, also just be reduced to the content of nitride and sulfide in the flue gas, the flue gas of cooling enters in the atmosphere through discharge flue again, and exhaust gas temperature is lower than 300 ℃, thereby realizes environment protection emission.The utility model heat exchange efficiency can reach 70%, and comprehensive heat utilization is up to 62.5%.2. sufficient combustion.The utility model adopts the automatic and separated burner, can realize that temperature controls automatically, and combustion atmosphere is controlled (oxidizing atmosphere, reducing atmosphere etc.) automatically.3. many warm areas are controlled automatically: the utility model is provided with a plurality of temperature sensors on body of heater, is used for multi-point temp in the perception stove, make thermometric accurate, but control accuracy is at ± 0.1 grade.4. furnace pressure is controlled.In discharge flue, be provided with gas fume valve, on body of heater, be provided with some pressure sensors, by the pressure in gas fume valve and the pressure sensor control stove.
