Background technology
When blast furnace maintenance, need temporarily out-of-blastly in the stove, open furnace roof manhole or manhole and overhaul.At this moment still having coal gas in the blast furnace exists, for guarding against gas poisoning or the generation of accident such as gas explosion, have and adopt artificial method the combustible of lighting to be lost the coal gas that ignites in the furnace roof and overflow by the furnace charge face, though this mode is simple to operate, if temperature is lower in the furnace roof, igniting just was difficult for successfully when the coal gas amount was less, need the artificial supervision condition of a fire or carry out regnition, this causes gas explosion in the furnace roof easily, not only increases labour intensity, also causes security incident easily.Chinese patent notification number: CN 2450218Y, the day for announcing: on September 6 calendar year 2001, proposed the utility model technical scheme that name is called " State of Blast Furnace summit firearm ".This scheme includes kindling material rifle, combustion-supporting gas flexible pipe and combustion-supporting air valve, gas hose and burnt gas valve, the spark ignition head that the pulse firing device is connected with lead, the kindling material rifle is fixed on the dolly, dolly is contained on the guide rail and with haulage gear and is connected, can move along guide rail, the internal layer Gas Pipe of kindling material rifle is connected with gas hose, and outer combustion-supporting tracheae is connected with combustion-supporting gas flexible pipe.The kindling material rifle can provide stable kindling material in furnace roof, do not need manually to monitor the condition of a fire, and igniting is quick, and is not flame-out, alleviated labour intensity and also guaranteed safety.But this device can't be learnt the situation of the interior gas content of blast furnace, because the moment of igniting does not know that whether the coal gas of furnace roof this moment and the content of oxygen reach explosive range, exist the danger of blast when therefore lighting a fire.And this device also can't be regulated and control gas componant in the blast furnace and content.
Summary of the invention
The purpose of this utility model is to understand and grasp the defective of blast furnace composition of gases within and content at igniter in the prior art, and a kind of State of Blast Furnace summit fire device of measuring and regulating furnace gas is provided.
Another purpose of the present utility model is the defective that can't regulate and control the gas componant in the blast furnace and content at igniter in the prior art, and a kind of State of Blast Furnace summit fire device of measuring and regulating furnace gas is provided.
In order to realize above-mentioned purpose, the utility model adopts following technical proposals: a kind of State of Blast Furnace summit fire device, it is by drive unit, guider, burner, guided bearing device and extraneous gas pipeline are formed, the extraneous gas pipeline is connected with burner respectively, the extraneous gas pipeline is made of fuel gas pipeline and combustion-supporting gas pipeline at least, what burner stretched into high furnace interior a bit is provided with gas sensor, described gas sensor is connected through the instrument of lead with the blast furnace outside, perhaps burner is provided with exhaust tube, one end of exhaust tube is connected with stove gas componant detecting instrument outward, and the bleeding point of the exhaust tube other end is arranged on burner and stretches on any of high furnace interior.
When burner extend into high furnace interior, gas sensor or detecting instrument can detect the concentration and the content of furnace gas, if the gas componant that records in the furnace roof inner space has explosion danger, igniter temporarily misfires, or take measures to change the concentration and the content of gas, treat that the gas componant in the furnace roof inner space does not have to light a fire behind the explosion danger again, blasts when avoiding lighting a fire.
Described extraneous gas pipeline is made of fuel gas pipeline, combustion-supporting gas pipeline and nitrogen or jet chimney, and nitrogen or jet chimney are connected in parallel on the fuel gas pipeline, or is connected in parallel on the combustion-supporting gas pipeline.
Compared with prior art, the beneficial effects of the utility model are: 1, can in time understand and grasp the composition of gas in the blast furnace and the situation of concentration, and the operation of in good time lighting a fire is for the maintenance construction of blast furnace provides safety guarantee; 2, increased the function that blast furnace internal gas composition and concentration are regulated, can in time in blast furnace, send into nitrogen or steam, reduce coal gas and concentration of oxygen, make it to meet the requirement of safety ignition, shortened the time of blast furnace maintenance construction, improved work efficiency.3, simple in structure, easy to operate, make the blast furnace maintenance construction safer, convenient and quick, be suitable for original State of Blast Furnace summit fire device is transformed.
Description of drawings
Fig. 1 is the structural representation of the utility model State of Blast Furnace summit fire device.
Among the figure: drive unit 1, detecting instrument 2, guider 3, fuel gas pipeline 4, combustion-supporting gas is stopped pipeline 5, nitrogen or jet chimney 6, burner 7, extraneous gas pipeline 8, gas sensor 9.
The specific embodiment
Below in conjunction with the description of drawings or the specific embodiment the utility model is described in further detail.
Referring to Fig. 1, a kind of State of Blast Furnace summit fire device, it is made up of drive unit 1, guider 3, burner 7, guided bearing device and extraneous gas pipeline 8, extraneous gas pipeline 8 is connected with insertion pipe on the burner 7 respectively, extraneous gas pipeline 8 is made of combustible gas pipeline 4 and combustion-supporting gas pipeline 5 at least, fuel gas pipeline 4 can be carried coal gas, liquefied gas etc., but combustion-supporting gas pipeline 5 delivering oxygens, compressed air etc.Be provided with a fuel gas pipeline 4 and carry coal gas in Fig. 1, be provided with combustion-supporting gas pipeline 5 delivering oxygens, another combustion-supporting gas pipeline 5 is carried compressed air.The suitable point that burner 7 stretches into high furnace interior is provided with gas sensor 9, described gas sensor 9 is connected through the Displaying Meter of lead with the blast furnace outside, gas sensor 9 can be the carbon monoxide transducer of market sale, or oxygen level sensor, it can detect the composition and the content of coal gas and oxygen in the gas.Sensor 9 is fixed on the outer wall of burner 7, is connected by the Displaying Meter of lead with the blast furnace outside, and sensor 9 can reach the outer Displaying Meter of stove with the form of the signal of telecommunication with the coal gas that records and concentration of oxygen, and Displaying Meter is arranged on the furnace roof outer platform.Displaying Meter and sensor 9 are complementary, and can demonstrate the composition and the concentration of sensor 9 measured gases.
