Description
Technical field
The utility model relates to field of metallurgy, especially relates to a kind of temperature-detecting device of U.S. steel connection method Continuous Hot Dip Galvanizing Annealing Furnace exhaust piping.
Background technology
In zinc-plated production run, the annealing furnace heating system is mainly the radiant tube heating, and the residue high-temp waste gas that heating produces is collected in the exhaust piping of each layer earlier, concentrates discharging by trunk line again.Regulate reasons such as improper, combustion air pressure surge, fuel gases calorific value fluctuation, leakage owing to air-fuel ratio and caused and have air and inflammable gas in the exhaust piping in a large number, enter exhaust piping at high temperature to mix, secondary combustion occurs.The temperature of secondary combustion product is often above 1000 ℃.The material that exhaust piping and corrugated tube are selected for use is 1Cr18Ni9Ti, and its long-term serviceability temperature under well-oxygenated environment generally should not surpass 800 ℃, but under various uncertain factor influences, exhaust gas temperature is easy to exceed.In the design, the insulating of exhaust piping and the thick ceramic fiber blanket of corrugated tube outer wrapping 100mm is made external protective material with the galvanized sheet of δ=0.5mm then.Like this, in the production use, the situation of exhaust piping can't be understood, and has only the dismounting insulating, could be from appearance it being checked.Not only time-consuming taking a lot of work also can make the construction quality of insulating be difficult to ensure because of the problem of repair time, influences outward appearance U.S. of entire equipment.Most critical be, secondary combustion produces high temperature exhaust piping inside is begun to burn out, its damaged condition on earth how, only from visual examination still can not be veritably, add their confirmation in all directions.Pipeline damages and will cause unit to stop production and security incident.
The utility model content
Technical problem to be solved in the utility model provides a kind of zinc-plated annealing furnace exhaust piping temperature-detecting device that can the zinc-plated annealing furnace exhaust piping of effective monitoring temperature.
The technical scheme that its technical matters that solves the utility model adopts is: zinc-plated annealing furnace exhaust piping temperature-detecting device, comprise the exhaust piping that is connected on the zinc-plated annealing furnace, it is characterized in that: be provided with the thermopair that is used to detect the gas in the tube wall in the tube wall of described exhaust piping.
Be provided with a plurality of radiant tubes in the zinc-plated annealing furnace, a plurality of thermopairs are arranged at respectively in the tube wall of two exhaust pipings between the radiant tube.
Described thermopair is separately positioned in the exhaust piping tube wall of zinc-plated annealing furnace fore side and transmission side.
The beneficial effects of the utility model are: zinc-plated annealing furnace exhaust piping temperature-detecting device can detect the temperature of gas in the exhaust piping in real time, temperature surpasses going up in limited time of setting in pipeline, zinc-plated annealing furnace exhaust piping temperature-detecting device will send signal, the prompt facility operating personnel make corresponding processing according to actual conditions, obtain reasonably air-fuel ratio, for ability performance, safety in production and the energy conservation of zinc-plated annealing furnace plays a key effect, prevent the generation of exhaust piping burning damage accident, make whole exhaust piping be in safe running status all the time.
Description of drawings
Fig. 1 is a scheme of installation of the present utility model;
Fig. 2 is the cut-open view of A-A among Fig. 1.
Be labeled as exhaust piping 1, radiant tube 2, thermopair 3 and tube wall 4 among the figure.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As depicted in figs. 1 and 2, zinc-plated annealing furnace exhaust piping temperature-detecting device of the present utility model comprises the exhaust piping 1 that is connected on the zinc-plated annealing furnace, is provided with the thermopair 3 that is used to detect the gas in the tube wall 4 in the tube wall 4 of described exhaust piping 1.Thermopair 3 is arranged in the tube wall 4 of exhaust piping 1, contact with the gas in the exhaust piping 1, can effectively detect the temperature of gas in the exhaust piping 1, the actual conditions that the equipment operator detects according to this device are made corresponding processing, obtain reasonably air-fuel ratio, make exhaust piping 1 be in safe running status all the time.
Be provided with a plurality of radiant tubes in the zinc-plated annealing furnace, radiant tube is distributed in transmission survey and fore side, exhaust piping also is distributed in the transmission survey and the fore side of each layer, and the waste gas that exhaust piping is collected each layer radiant tube focuses on exhaust gas heat exchanger at last to carry out discharging after the heat interchange.A plurality of thermopairs are arranged at respectively in the tube wall of two exhaust pipings between the radiant tube.Be provided with like this can be in whole exhaust piping 1 tube wall 4 even distributed heat galvanic couple, whole exhaust piping 1 can both effectively be detected.If secondary combustion phenomenon or other superheating phenomenon take place in the part of exhaust piping 1, thermopair 3 herein will send signal, the equipment operator just can find overheated place accurately according to signal, make these thermopair 3 anterior burners of suitable adjustment air-fuel ratio, close the control panel of these thermopair 3 anterior burners, and close the treatment measures such as sky, gas valve of burner herein, prevent the generation of local overheating phenomenon.
