Abstract
The utility model relates to a blast furnace tuyere water leakage alarm device, which comprises a tuyere water inlet flow meter, a tuyere water outlet flow meter and an alarm; the tuyere water inlet flow meter is arranged on a blast furnace tuyere water inlet pipe, the tuyere water outlet flow meter is arranged on a blast furnace tuyere water outlet pipe, the alarm is arranged in the central control room, and the tuyere water inlet flow meter and the tuyere water outlet flow meter are respectively connected with the alarm through communication lines. The tuyere water inlet flow meter and the tuyere water outlet flow meter are remote water meters. The utility model discloses can discover the bad sign in wind gap as early as possible, in time make the processing, avoid the too much phenomenon that leaks into the blast furnace and lead to the abnormal burnt ratio of heat balance to rise, the energy consumption increases. The utility model has simple measures, low cost and easy operation, prolongs the service life of the blast furnace and can bring better economic benefit.
Description
Technical field
The utility model relates to blast-furnace smelting detection field, particularly Blast Furnace Tuyere Leakage warning device.
Background technology
Modernization metallurgy industry, the ultimate aim of blast-furnace smelting is summarised as eight words, high yield, low consumption, long-lived, environmental protection.In blast furnace ironmaking process, due to the wearing and tearing of coal rifle, weld bond quality, liquid slag iron contacts, and the slag crust reason air port such as to come off is damaged.Owing to finding not in time, diminishing is not in place or delayed, causes air port water coolant directly to leak toward in cupola well.Blast-furnace smelting is energy consumption consumption rich and influential family, and reducing consumption principal element is reduce coke ratio, and cooling apparatus leaks and occurs that high wind-warm syndrome is the major reason causing coke ratio to raise.Water coolant leaks toward cupola well, and also can affect blast furnace work-ing life, improve ton iron cost, cause iron mouth abnormal time serious, iron mouth easily sprays, and slag iron goes out clean, affects the direct motion steady in a long-term of blast furnace.Therefore, how to find the sign that air port is bad early, it is the Important Action realizing blast furnace low consumption that minimizing cooling apparatus leaks in blast furnace.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Blast Furnace Tuyere Leakage warning device, finds the sign that air port is bad early, and minimizing drains to cooling water inflow in blast furnace as far as possible, guarantees the normal production of blast furnace.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of Blast Furnace Tuyere Leakage warning device, comprises air port feed water flow scale, air port water flow table, warning howler; Air port feed water flow scale is arranged on blast-furnace tuyere water inlet pipe, and air port water flow table is arranged on blast-furnace tuyere rising pipe, and warning howler is arranged in Central Control Room, and air port feed water flow scale is connected with warning howler respectively by communication link with air port water flow table.
Described air port feed water flow scale and air port water flow table are remote transmitting water meter.
Compared with prior art, the beneficial effects of the utility model are:
A kind of Blast Furnace Tuyere Leakage warning device, can find the sign that air port is bad early, deal with in time, causes the phenomenon that the not normal coke ratio of thermal equilibrium raises, energy consumption increases in the blast furnace that bleeds avoiding water coolant too much.The utility model measure is simple, with low cost, easy to operate, improves blast furnace work-ing life, can bring good economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the water flow table 3-warning howler 4-blast-furnace tuyere water inlet pipe of feed water flow scale 2-air port, 1-air port
5-blast-furnace tuyere rising pipe 6-blast-furnace tuyere 7-communication link 8-Central Control Room
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of Blast Furnace Tuyere Leakage warning device, at blast-furnace tuyere water inlet pipe 4, air port feed water flow scale 1 is installed, install air port water flow table 2 at blast-furnace tuyere rising pipe 5, air port feed water flow scale 1 is connected with the warning howler in Central Control Room 8 respectively by communication link 7 with air port water flow table 2.Described air port feed water flow scale 1 and air port water flow table 2 are remote transmitting water meter.Blast-furnace tuyere imports and exports the flux values that water flowmeter detects Inlet and outlet water respectively, and the numerical value of each rate of flow meter is access on the warning howler 3 of Central Control Room.Once find that water flow is less than flooding velocity, namely warning howler 3 reports to the police.At this moment can judge that there is bad sign in air port, carry out manual diminishing operation, avoid water coolant to continue to drain in blast furnace.
Be only ultimate principle of the present utility model above, not impose any restrictions the utility model, every foundation the utility model carries out equivalent variations and modification to it, all within the category of the art of this patent protection scheme.
Claims (2)
1. a Blast Furnace Tuyere Leakage warning device, comprises air port feed water flow scale, air port water flow table, warning howler; Air port feed water flow scale is arranged on blast-furnace tuyere water inlet pipe, and air port water flow table is arranged on blast-furnace tuyere rising pipe, and warning howler is arranged in Central Control Room, and air port feed water flow scale is connected with warning howler respectively by communication link with air port water flow table.
2. a kind of Blast Furnace Tuyere Leakage warning device according to claim 1, is characterized in that, described air port feed water flow scale and air port water flow table are remote transmitting water meter.
