By utilizing the temperature measurement gun provided by the invention, the temperature at any point of the surface of the furnace tube can be measured; and the temperature measurement gun is suitable for wall temperature measurement of a reformer furnace tube and a tube type heating furnace tube in devices for ammonia synthesis, oil refining, petroleum chemical industry and natural gas chemical industry.
Description
Technical field
The invention belongs to the stove field of the progressive heating of stationary furnace, relate to heating furnace tube pipe surface temperature measuring equipment, a kind of especially temperature-measuring gun of measuring tube skin temperature.
Background technology
Heating furnace is the equipment with material or workpiece heating.By the thermal source division fuel heating furnace, resistance-heated furnace, induction heater, microwave oven etc. are arranged.Application spreads all over many industry fields such as oil, chemical industry, metallurgy, machinery, thermal treatment, surface treatment, building materials, electronics, material, light industry, daily use chemicals, pharmacy.
With the hydro carbons is raw material, adopts steam reforming to produce synthetic raw gas and hydrogen, has crucial status in industry such as synthetic ammonia, oil refining, petrochemical complex, gas chemical industry, metallurgy.Reburner is the key equipment of hydrocarbon steam conversion technological process, and the reformer tube of reburner is the key equipment of reburner.These boiler tube maximum tube wall temperatures are all more than 800 ℃, and service condition is very harsh, and misoperation is very easy to cause damage.
Overheated and the thermal stress of boiler tube is the principal element that converting furnace damages, edit by Qian Jialin, Sinopec publishing house, the 432nd page of introduction of " tubular heater " second edition of publishing in August, 2007: 1/10th when converting furnace is 900 ℃ the serviceable life in the time of 970 ℃.Therefore, for preventing the boiler tube over temperature and heat, the long-life safe operation of assurance device is very important to real-time monitoring of tube skin temperature.
Chen Yanze, Chou Xingqi, Yang Xiangping, in the petrochemical equipment technology, 2000,29 (5) exercise questions of delivering are the article introduction of " temperature distributing disproportionation is even to crooking of the tubes deformation effect ": certain refinery tipburn hydrogen manufacturing conversion furnace, boiler tube in service bends, and is serious near the crooking of the tubes of furnace wall, about 6 ° of up, the flexural deformation of boiler tube might cause boiler tube to break, thereby causes major accident to take place.By the temperature field of SECTION TUBE FOR HYDROGEN MANNU-FACTURING FURNACE radiation chamber is distributed, furnace tube temperature distributes and the calculating of boiler tube thermal stress etc., reach a conclusion after analyzing: circumferentially temperature distributing disproportionation is even on the boiler tube surface is the main cause of crooking of the tubes distortion.
So far, because lack reliably, furnace wall temperature field measurement Method and kit for fast, in the actual production process of reburner, also can't accurately measure circumferentially multi-point temp of boiler tube surface, even measure the local temperature on boiler tube surface certain a bit, accurately measure also very difficult.At present, the boiler tube pipe surface temperature is measured the main infrared method that adopts: infrared temperature-measuring gun and thermal infrared imager.
But the measuring error of infrared method is very big, usually exceeds much than actual temperature.Li Jihong, Zhong Jisheng, at the petrochemical complex Journal of Chinese Universities, 1995,8 (2) " with Infrared Physics method on-line monitoring high temperature furnace pipe surface temperature field " article introductions of delivering: in the environment of high-temperature flue gas and flame, utilize infrared method to measure the Temperature Distribution of body surface, it is a problem that difficulty is very big, in fact, the infrared emanation on certain root boiler tube surface is subjected to the radical of boiler tube on every side and distribution, from the influence of the factors such as position of flame and furnace wall, and in infrared computation model and reckon without the effect of above factor, this is the main cause that causes error.On the other hand, the high-temperature region of boiler tube is all near central axis on the thermography, be not that boiler tube both sides temperature is low, because the heat radiation of object all is perpendicular to the surface to extraradial, to boiler tube, the strongest in the face of near the heat radiation the central axis of boiler tube, disalignment is many more, the heat radiation that instrument is accepted is few more, and this also is the reason that causes measuring error.In addition, the setting of boiler tube emissivity also will cause certain error.
Zhao Weili, at big nitrogenous fertilizer, 2005,28 (1) " application of infrared thermal imaging technique in one-stage converter " article introductions of delivering: the boiler tube and the stove outer wall of tower southwest Zepu large chemical fertilizer factory one-stage converter carry out infrared periodic monitoring.According to the temperature data that infrared monitoring provides, measure the development trend of furnace wall temperature; At detecting the problem of finding, timely adjusting process index.Network address:
Http:// www.pmec.net/bencandy-58-5611-1.htmThe network document of delivering " infrared diagnosis technology is in the application of petrochemical industry " is introduced: the one-stage converter of certain chemical fertilizer factory has 180 boiler tubes, temperature distributing disproportionation, and the part boiler tube is overheated.Utilize infrared thermometer to carry out the furnace tube temperature test, observe from the flame-observing hole of each layer platform, IR image display boiler tube maximum temperature reaches 1023 ℃ as a result, calculates that the boiler tube maximum temperature is 998 ℃ behind the eliminating disturbing factor.This shows that the infrared measurement of temperature result is inaccurate, just credible after needing to proofread and correct, but how many corrected values is, depends reckoning alone and can't stand.
At present, adopt the contact temperature-measuring instrument to compare both at home and abroad usually, to determine infrared method measuring error corrected value with measuring the testee temperature.But also do not have the special-purpose temperature measurer of converting furnace at present, the similar contact temperature-measuring of other industry mostly is straight-bar type single-point thermometric greatly, can only measure the testee front face surface, and energy measurement backside surface not more can not the multimetering front, the back side, side.Disclose a kind of temperature-measuring gun that can change thermocouple head continuously automatically as Chinese patent ZL03210083.3, be used to solve the artificial problem of changing of prior art temperature-measuring gun thermocouple head.Chinese patent ZL93228664.X discloses the fast high-temperature sensing rifle, solve in the prior art the radially problem of thermometric difficulty, Chinese patent ZL91201692.2 discloses metallic ceramics thermopair combined type quick temperature measurement rifle, solve thermometric end and cold junction heat-insulating problem in the prior art, but do not disclose any place in the prior art and measure circumferential any point method of temperature of boiler tube and equipment, multi-point temp how correctly to measure the boiler tube surface is this area problem demanding prompt solution.
