After using technique scheme, the coke dry quenching furnace liner online test method of the present invention has the advantage that
1, preferably solve coke dry quenching furnace liner examinations in process of production, a difficult problem for monitoring；
2, produce offer sound assurance for dry coke quenching, provide clear and definite scope for the maintenance of coke dry quenching furnace liner；
3, coke dry quenching furnace liner online test method is simple, workable.
Accompanying drawing explanation
Fig. 1 is the coke dry quenching furnace liner online test method schematic diagram of the embodiment of the present invention；
Fig. 2 be the embodiment of the present invention coke dry quenching furnace in keyhole scattergram.
In figure: 1 high temperature picture pick-up device, 2 resistant to elevated temperatures data wires protection pipes, 3 high temperature photographic head, 4 coke dry quenching furnace cooling sections, 5 put out furnace chute strut brick, 6 coke dry quenching furnace annular passages, and 7 coke dry quenching furnace prestore room, keyhole in 8 coke dry quenching furnace, keyhole layer platform in 9,10 disposable dust removers.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
Referring now to the coke dry quenching furnace liner online test method schematic diagram that Fig. 1-2, Fig. 1 are the embodiment of the present invention, Fig. 2 be the embodiment of the present invention coke dry quenching furnace in keyhole scattergram.
Coke-oven plant's 140t/h dry coke quenching, chute strut brick is divided into 36, and middle keyhole is divided into 36, after being constructed and put into operation 2 years, uses the coke dry quenching furnace liner online test method of the embodiment of the present invention, specifically comprises the following steps that
1) detect the installation of equipment: high temperature picture pick-up device is arranged on keyhole layer platform in dry coke quenching, connect water source, power supply, wind regime.Connect high temperature photographic head and resistant to elevated temperatures data wire protection pipe, debug high temperature shooting and the interface of display.
2) processing parameter in coke dry quenching furnace is adjusted: stop dress Jiao during detection, the controlling level of coke in stove is dropped to chute with lower portion；The gas pressure of room of controlling to prestore in coke dry quenching furnace is-50pa.
