Abstract
The utility model relates to a flue gas residual heat utilization apparatus for industrial furnaces, comprising the industrial furnace 1, a hot air preheater 2, a flue 3, a bypass flue 4, a branch flue 5, a residual heat boiler 6, an induced draft fan 7 and a chimney 8. A flue brake 9 is arranged in the flue 3, one end of the flue brake is connected with the industrial furnace 1 through the hot air preheater 2, and the other end is connected with the chimney 8; flue brakes 10, 11 which are arranged in the bypass flue 4 are connected with the residual heat boiler 6 in series; a flue brake 12 and the induced draft fan 7 are connected in series in the branch flue 5, one end of the branch flue 5 is connected with the bypass flue 4, and the other end id connected with a pickling tank or a phosphorization tank or a saponification tank 13. Because the utility model increases the residual heat boiler and the residual heat utilization apparatus at the back of the hot air preheater (or directly at the furnace end of the industrial furnace), the high-temperature flue gas residual heat of the industrial furnace can be fully utilized (the exhaust temperature through the hot air preheater, the residual heat boiler and the residual heat utilization apparatus is about 80 DEG C).
Description
Technical field
The utility model relates to the industrial furnace residual heat using device of metallurgy industry iron and steel steel (pipe) production and processing industries, particularly a kind of industrial furnace high-temperature fume afterheat use device.
Background technology
At present, the industrial furnace overwhelming majority in the present technology all is to adopt the hot-air pre-heating device to carry out UTILIZATION OF VESIDUAL HEAT IN.The hot-air pre-heating device can only drop to the flue-gas temperature in the industrial furnace about 580 ℃ by original about 750 ℃, still contains a large amount of heat energy in its flue gas and is not fully used.Meanwhile, need steam heated again in enterprise's pickling tube or the phosphatization pond, need to consume a large amount of energy, both be unfavorable for that enterprise reduces production costs, cause environmental pollution again and produce steam by boiler.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of industrial furnace high-temperature fume afterheat use device is provided.
The technical solution of the utility model is: industrial furnace high-temperature fume afterheat use device comprises industrial furnace, flue, by-pass flue, waste heat boiler and chimney, the cigarette lock is arranged in the flue, the one end is connected with industrial furnace tail, the other end is connected with chimney, the cigarette lock is arranged in the by-pass flue and and be serially connected with waste heat boiler.
The technical solution of the utility model also can be: the high-temperature flue gas residual heat using device comprises industrial furnace, hot-air pre-heating device, flue, by-pass flue, waste heat boiler and chimney, the cigarette lock is arranged in the flue, the one end is connected with industrial furnace tail by the hot-air pre-heating device, the other end is connected with chimney, the cigarette lock is arranged in the by-pass flue and and be serially connected with waste heat boiler.
The further technical scheme of the utility model is: the high-temperature flue gas residual heat using device also comprises the branch flue that is connected with by-pass flue, is serially connected with residual heat using device and air-introduced machine in the branch flue.
The utility model since behind the hot-air pre-heating device (or directly at industrial furnace tail) increased waste heat boiler and residual heat using device, can fully the industrial furnace high-temperature fume afterheat all be utilized (through about about 80 ℃ of exhaust gas temperature after hot-air pre-heating device, waste heat boiler and the residual heat using device).Can produce steam with waste heat boiler, replace producing in the enterprise fire coal, fuel oil, the gas fired-boiler of steam,, reduce environmental pollution and investment in fixed assets, reduce the production cost of enterprise with energy savings; With air-introduced machine will through the high-temperature flue gas about 200 ℃ behind the waste heat boiler again through the residual heat using device utilization (replace steam heated as it being delivered in pickling tube or phosphatization pond or the saponification pond, can solve because of steam heated cause pickle or phosphatization liquid or saponification liquor often excessive causing cause raw material and environmental pollution problems).
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.
The specific embodiment
As shown in drawings: industrial furnace high-temperature fume afterheat use device comprises industrial furnace 1, hot-air pre-heating device 2, flue 3, by-pass flue 4, branch flue 5, waste heat boiler 6, air-introduced machine 7 and chimney 8, cigarette lock 9 is arranged in the flue 3, the one end gives hot device 2 by hot blast and is connected with industrial furnace 1, the other end is connected with chimney 8, cigarette lock 10 and 11 and be serially connected with waste heat boiler 6 are arranged in the by-pass flue 4, be serially connected with cigarette lock 12 and air-introduced machine 7 in the branch flue 5, the one end is connected with by-pass flue 4, and the other end and pickling tube or phosphatization pond or saponification pond 13 are connected.
When turning off cigarette lock 9,12, opened the cigarette lock at 10,11 o'clock, the high-temperature flue gas that temperature reaches about 580 ℃ after preheating wind-heat device UTILIZATION OF VESIDUAL HEAT IN enters by-pass flue 4 from flue 3, by waste heat boiler 6 once more after the UTILIZATION OF VESIDUAL HEAT IN, temperature drops to about 200 ℃, discharges through chimney from flue 3 again.
When turning off cigarette lock 9,11, open cigarette lock 10,12, start air-introduced machine 7, to reduce to high-temperature flue gas about 200 ℃ through hot-air pre-heating device 2 and waste heat boiler 6 twice UTILIZATION OF VESIDUAL HEAT IN temperature and deliver to and replace steam heated in pickling tube or phosphatization pond or the saponification pond 13, and can solve because of steam heated and cause often excessive problem of pickle or phosphatization liquid or saponification liquor.
