Abstract
Disclosed is a blast furnace top ignition device; a burner (2) is placed in a furnace top manhole (9); the other end of the burner (2) is hinged with the front end of a bridging base (1) extended into the furnace top manhole (9); a plane corresponding to the lower edge of the furnace top manhole (9) is arranged on the bottom surface of the middle part of the bridging base (1); and tail end of the bridging base (1) is located outside the blast furnace and connected with a fixed device (10). Without arranging holes on the frustum at the furnace top, the blast furnace top ignition device avoids gas leakage at the ignition hole and reduces the maintenance costs of the blast furnace. The burner (2) can be ignited at any time in case of flameout. The ignition device can usually be stored in any place to reduce the occupation of the effective working plane at the furnace top, which can be installed and used without making any alteration on the blast furnace.
Description
Technical field
The utility model relates to a kind of combustible gas lighter, especially a kind of State of Blast Furnace summit fire device.
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.Early stage widely used guide tracked dynamo exploder exists the high and bulky unsafe shortcoming of cost.
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 because the rear end of kindling material rifle is fixedly connected with gas hose and combustion-supporting gas flexible pipe, no matter gas hose and combustion-supporting gas flexible pipe are in the process that the igniting operation is moved with the kindling material rifle and are in connection status all the time under the storage configuration, the supporting device of flexible pipe is comparatively complicated, has increased the volume of cost and igniter.Simultaneously, it is bigger that this burning torch takies the space of furnace roof maintenance, the fire hole of also need on the furnace roof frustum, making war, this can weaken the intensity of furnace roof frustum, increase maintenance cost, carry out the manual firing outward if need also after the fire on the kindling material rifle puts out that the kindling material rifle is withdrawed from stove, operation is convenient inadequately, also can influence blast furnace production when fire hole leaks gas.
Summary of the invention
