Abstract

The utility model provides a non-contacting on-line measuring system of coke-oven fire channel temperature, belonging to the area of coke-oven automatic technic field, which comprises an infrared thermometer, a switch valve, a driving mechanism for switch valve and an ash blower. The infrared thermometer is installed on the fire watch hole of the coke-oven or the upside of the small oven cover, and aims at the temperature measuring position at the bottom of the coke-oven vertical fire channel. The infrared thermometer aims at the temperature measuring position at the bottom of the coke-oven vertical fire channel, and receives the infrared radiation energy, and then transforms the radiation energy into temperature signal to the display instrument. The advantages of the system are high measurement precision, automatic measurement process, reliable work performance, on-line and long time stable measurement, low investment, convenient operation. As new equipment for coke-oven fire channel temperature measurement, the system has a wide market foreground and economical benefits.

Description

Coke oven fire path temperature non-contact type on-line measurement system
Technical field:
The utility model belongs to the coke oven technical field of automation, is specifically related to coke oven fire path temperature non-contact type on-line measurement system.
Background technology:
China is coking production big country, the big and small coke oven in the whole nation has thousands of seats, coke oven mean flue temperature (standard fire path temperature) measurement in decades is by labor measurement always, be the surface temperature of operative employee, measured once in per 4 hours with contactless thermometer (leucoscope or portable infrared thermometer) manual measurement quirk bottom bridge of the nose brick.
The problem that prior art exists mainly contains: manual measurement is time-consuming, effort, working condition are poor, and measures and influenced greatly by human factor, and error is difficult to control.And artificial thermometric is not easy to realize the control of coke oven heating computer.
In recent years successively adopt the method for thermopair indirect temperature-measuring both at home and abroad, but the following problem that is difficult to overcome arranged:
(1) crosses over the hole from furnace roof and insert thermopair, measure and cross over the hole temperature.The weak point of this method: measurement point is the gas temperature in furnace roof space, and is different with present point for measuring temperature; Fall into quirk behind the casing failure of thermopair, easily cause quirk to stop up.
(2) insert thermopair from the regenerator top space, measure and hold temperature between head space.The weak point of this method: measurement point is to hold temperature between head space, need to set up the correlation model that holds temperature and fire path temperature between head space, but that this model is influenced by other factors is very big, and is often very inaccurate under the situation of variation in operating mode.
(3) survey temp measuring methods such as temperature of furnace wall at the pre-buried thermopair of furnace wall.The weak point of this method: difficulty is installed greatly for the coke oven of having built well; After damaging, thermopair has no idea to change.
Thermopair life-span in the flue gas atmosphere of reductibility is short.
Summary of the invention:
The utility model is to overcome the problem that exists in the existing coke oven fire path temperature measuring technique, and a kind of coke oven fire path temperature non-contact type on-line measurement system is provided, and this system can be online, measure total system compact conformation, low cost of manufacture steadily in the long term.
This system is made up of infrared thermometer, switch valve, switch valve driving mechanism, soot blower etc., infrared thermometer 1 wherein passes through thread connection with soot blower 2, and link to each other with switch valve 3 order, infrared thermometer 1 is installed in the coke oven peephole or the port side of covering of coke oven and aims at point for measuring temperature position bottom the coke oven flue.The switch of switch valve 3 is driven by switch valve driving mechanism 4.The simple type structure of this system is made up of infrared thermometer, soot blower etc.
Below in conjunction with Figure of description the utility model is done detailed explanation.
Fig. 1 is the utility model structural representation.On coke oven port lid 5, open a groove or tongue, switch valve 3 is fixed in the above, soot blower 2 passes through thread connection with infrared thermometer 1, and link to each other with switch valve 3, the switch of switch valve 3 is by the switch valve drive mechanism, when switch valve was opened, the infrared radiation of coke oven body inside just shone directly on the infrared thermometer 1, can directly measure coke oven fire path temperature.By adjusting the point for measuring temperature that the infrared thermometer stationary installation can make infrared thermometer 1 aim in the coke oven fire path.At the anterior gas shield that forms of infrared thermometer, stop the optical lens of smoke contamination infrared thermometer 1 by soot blower 2.The switch valve driving mechanism can be electromagnet or cylinder, because coke oven head temperature height, electromagnet or cylinder should be selected high temperature resistant type, and the working temperature upper limit should be not less than 100 ℃.Utilization driving mechanism 4 gauge tap valves 3 guarantee the measuring channel fast opening and closing, close the measurement passage when long-time off working state, are beneficial to prolong the serviceable life of system.
Fig. 2 is a simple type structural representation of the present utility model.In this system, cancelled switch valve and switch valve driving mechanism, infrared thermometer 1 directly links to each other with coke oven port lid 5 by soot blower 2, directly receives the infrared energy of body of heater.The ash gas that blows of soot blower 2 directly enters body of heater, and in order to reduce to enter the gas flow of body of heater, blowing grey air pressure should be controlled at about 100Pa.
Description of drawings:
Fig. 1: the utility model structural representation
Fig. 2: simple type structural representation of the present utility model
Fig. 3: the utility model is applied to the work synoptic diagram of thermometric
Among the figure: 1: infrared thermometer; 2: soot blower; 3: switch valve; 4: the switch valve driving mechanism;
5: the little bell of coke oven; 6: computer supervisory control system; 7: load module; 8: measuring system of the present utility model.
Embodiment:
See Figure of description 3, the JN60 Formed Coke Furnace, 65 hole carbonization chambers, select ten heat (batch) numbers respectively in machine survey and burnt the survey, be respectively 25#, 27#, 29#, 31#, 33#, 35#, 37#, 39#, 41#, 43#, the 8th peephole (machine survey) and the 20th peephole (coke side) at each heat (batch) number are gone up installation coke oven fire path temperature non-contact type on-line measurement device 8, the infrared thermometer model is the FA1 infrared optical fiber thermometer of thunder great-grand father department, power supply is 24VDC, output signal is the 4-20mADC of standard, by standard 4-20mA load module 7 temperature data is transported in the computer supervisory control system 6, computer supervisory control system is the JX300 collective and distributive type control system of SUPCON.Respectively ten coke oven fire path temperatures of pusher side and coke side are asked on average, coke oven fire path temperature is a continually varying, exchanges back 5 minutes pusher side, coke side mean value as final coke oven machine, coke side fire path temperature when taking off sending down abnormally ascending stream.
