Background technology
In blast furnace was produced, various types of water-cooled water coolers had been subjected to the mechanical wear of stress impact, heat erosion, injection material for a long time in blast furnace, cause micro-leakage loss to occur.Damage for these trace is leaked, and adopts existing technology and equipment all to be difficult to effectively detect.When there is leakage loss in water cooler, because the cooling water pressure in the water cooler is greater than the State of Blast Furnace internal pressure, water coolant will directly enter in the stove, when reaching certain water leakage, water is reduced to hydrogen and oxygen, not only consumes a large amount of heats, cause furnace temperature to descend, and when serious, even can cause the stove cold, cause blast furnace can't keep normal operation.
The utility model content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of blast furnace water-cooling water cooler leak-checking apparatus, in order to the leakage loss situation of online detection blast furnace water-cooling water cooler.
For achieving the above object, the utility model adopts following technical scheme:
This blast furnace water-cooling water cooler leak-checking apparatus comprises boot last air collector, spherical float and float sensor, and the boot last air collector is the big down little variable-diameter structure that, and its underpart one is connected to the water shoot of blast furnace water-cooling water cooler, and the other end is provided with rising pipe; Spherical float is located in the top of boot last air collector, and the afterbody of spherical float passes the boot last air collector and links to each other with the float sensor of being located at boot last air collector outer wall.
Described boot last air collector top also is connected with spherical gas-holder, also is provided with the coal gas probe on the spherical gas-holder.
Described spherical gas-holder upper end also is connected to a coal gas burner, also is respectively equipped with automatic ignitor and temperature sensor in coal gas burner one side.
Described water shoot is provided with tensimeter, and described rising pipe is provided with outlet valve.
Also be connected to a vent valve between described boot last air collector and the spherical gas-holder.
Also be connected to combustion valve and throttle orifice between described spherical gas-holder and the coal gas burner successively.
In technique scheme, blast furnace water-cooling water cooler leak-checking apparatus of the present utility model comprises boot last air collector, spherical float and float sensor, and boot last air collector bottom one is connected to the water shoot of blast furnace water-cooling water cooler; Spherical float is located in the top of boot last air collector, and links to each other with float sensor.By adjusting the water cooler internal pressure far below furnace pressure, if water cooler has leakage loss, then coal gas can enter water cooler by the leakage loss place in the stove, and enters boot last air collector inside with water coolant, and in jar, produce bubble and press down float, and then send detection signal by float sensor.In addition, also can to whether coal gas is arranged in the gas-holder detect, equally also can effectively detect the leakage loss situation of water cooler by modes such as coal gas probe and burnings.
Description of drawings
Fig. 1 is the structural representation of blast furnace water-cooling water cooler leak-checking apparatus of the present utility model;
Fig. 2 is the A portion enlarged diagram among Fig. 1.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 1, shown in Figure 2, blast furnace water-cooling water cooler leak-checking apparatus 10 of the present utility model comprises boot last air collector 11, spherical float 12 and float sensor 13, boot last air collector 11 is the big down little variable-diameter structure that, can adopt stainless steel sheet to make, this structure can reduce the flow velocity of water coolant in air collector 11 greatly, make bubble that enough floating interval of floating dock be arranged in air collector 11, reach the effect of gas-liquid separation.Its underpart one is connected to the water shoot 2 of blast furnace water-cooling water cooler 1, and the other end is provided with rising pipe 111, also is provided with outlet valve 112 on the rising pipe 111; Spherical float 12 is located in the top of boot last air collector 11, the afterbody of spherical float 12 passes boot last air collector 11 and links to each other with the float sensor 13 of being located at boot last air collector 11 outer walls, and float sensor 13 can send a high position, two kinds of detection signals of low level according to the variation of float 12 height.As an embodiment, also be connected with spherical gas-holder 14 at described boot last air collector 11 tops, also be provided with coal gas probe 15 on the spherical gas-holder 14, and between described boot last air collector 11 and spherical gas-holder 14, also be connected to a vent valve 16.As another embodiment, also be connected to a coal gas burner 17 in described spherical gas-holder 14 upper ends, also be respectively equipped with automatic ignitor 18 and temperature sensor 19 in coal gas burner 17 1 sides, automatic ignitor 18 and temperature sensor 19 are fixed on the top of boot last air collector 11 by support 22, and between described spherical gas-holder 14 and coal gas burner 17, also be connected to combustion valve 20 and throttle orifice 21 successively, throttle orifice 21 be provided with the flameholding that is beneficial to burner 17.In addition, in use, also need on the water shoot 2 of water cooler 1, be provided with tensimeter 4, and water inlet variable valve 3 is set on the water inlet pipe 5 of water cooler 1, in order to regulate water cooler 1 internal pressure.
