Abstract
The utility model relates to an extinguishing-proof furnace top burning torch, which comprises a combustion-supporting air pipe and an internal combustion air pipe that is arranged in the combustion-supporting air pipe, wherein the end part of the combustion-supporting air pipe takes the cone shape to form a mixing chamber. The furnace top burning torch is characterized in that a spiral slug is arranged at the outlet of the internal combustion air pipe; a central passage is arranged on the spiral slug along the axis direction; inclined holes communicated with outside at intervals are arranged at the side wall of the spiral slug along the periphery direction at the tail end of the central passage; and the tail end of the central passage is of a closed structure. The extinguishing-proof furnace top burning torch improves the muzzle flame lifting of the burning torch, ensures one-time firing at the furnace top, shortens the damping-down firing time and avoids the affection to damping-down process.
Description
Technical field
The utility model belongs to ignition technique field, State of Blast Furnace summit, particularly a kind of anti-type furnace top burning torch that puts out.
Background technology
The burning torch that uses is to be fixed on the dolly at present, and dolly then is contained on the guide rail, and can move along guide rail, and dolly connects steel cable again simultaneously, and steel cable is connected with haulage gear again.Burning torch is a two-layer pipe, and as shown in Figure 1, internal layer gas line 10 is connected with gas hose, and outer combustion-supporting tracheae 20 is hose connection with combustion-supporting gas.After burning torch was lighted and mixed combustion air, because Sweet natural gas is wrapped in and fails thorough mixing in the combustion air, the rifle head easily produced the situation of taking off fire.Because have certain pressure reduction inside and outside the stove, the moment fire of burning torch in entering stove just put out, need repeatedly pilot fire during igniting; can't determine ignition time, need keep an eye on by the special messenger after the igniting that phenomenon takes place to extinguish automatically in regular meeting; influence field staff's safety, again igniting again.
Former furnace top burning torch can provide long distance ignition, but can't guarantee not extinguish after the success ratio of furnace roof igniting and the igniting.
Summary of the invention
The purpose of this utility model is to design a kind ofly anti-puts out the type furnace top burning torch, improves the burning torch muzzle and takes off fiery phenomenon, guarantees once success of furnace roof igniting, shortens damping down ignition time, avoids influencing the damping down process.
The technical solution of the utility model is,
A kind ofly anti-put out the type furnace top burning torch, comprise combustion-supporting tracheae, be arranged at combustion-supporting endotracheal in gas line; Combustion-supporting tracheae end is tapered, forms a mixing section; It is characterized in that the spiral fuse is installed in described interior gas line exit, the spiral fuse has centre channel along axis direction, and the spiral fuse sidewall of centre channel end is along the circumferential direction offered inclined hole interlinked with the outside at interval; This centre channel end is an enclosed construction.
Further, described helix core subcenter channel end along the circumferential direction at interval 120 degree offer inclined hole.
Again, described spiral fuse and interior gas line exit are that spiral is connected.
The aperture of described centre channel and inclined hole is less than internal combustion tracheae bore 30mm.
At the burning torch muzzle spiral fuse is installed, the helix core subcenter has through hole, front end has connecting thread to be connected with muzzle, terminal 360 degree circumferential direction equal portions are offered inclined hole at interval, guaranteed gas pressure and flow velocity and can evenly effectively mix with combustion air, the end sealing can be burnt by thorough mixing Sweet natural gas and air, prevents that muzzle from taking off fire.Because the inclined hole caliber size directly influences the flow velocity of Sweet natural gas by muzzle on burning torch rifle head helix core subcenter through hole bore and the circumference, after repetition test, the aperture of central through hole and inclined hole is set to less than internal layer gas line bore 30mm, improve the flow velocity of Sweet natural gas at the igniting muzzle, keep stable gas pressure, the natural pore of oblique muzzle and the terminal hole of ending also prevent tempering phenomenon simultaneously.Improve the back and guarantee once success of furnace roof igniting, guaranteed ignition time.
The beneficial effects of the utility model
The utlity model has good gas mixed effect, structure of modification is simple, and it designs realistic demand, solves the blast furnace burning torch conscientiously and takes off fiery phenomenon.Spiral fuse in the device can be with in Sweet natural gas uniform distribution and the combustion air, and mixing section can further provide mixing space, in addition combustion air and Sweet natural gas thorough mixing.Shorten damping down ignition time greatly, avoid influencing the damping down process.Guarantee field personnel's safety simultaneously, improved working efficiency.

Embodiment
Referring to Fig. 2～Fig. 4, of the present utility modelly a kind ofly anti-put out the type furnace top burning torch, comprise combustion-supporting tracheae 1, be arranged at the interior gas line 2 in the combustion-supporting tracheae 1; Combustion-supporting tracheae 1 end is tapered, forms a mixing section 101; Spiral fuse 3 is installed in gas line 2 exits in described, and spiral fuse 3 has centre channel 31 along axis direction, and spiral fuse 3 sidewalls of centre channel 31 ends along the circumferential direction compartment are offered inclined hole 32 interlinked with the outside every 120 degree; These centre channel 31 ends are enclosed construction.Described spiral fuse 3 is that spiral is connected with interior gas line 2 exits.The aperture of described centre channel 31 and inclined hole 32 is less than interior gas line 2 bore 30mm.
With three inclined holes 32 of natural gas transport to spiral fuse 3 ends, Sweet natural gas mixes with combustion-supporting even air in the combustion-supporting tracheae 1 outside inclined hole 32 by spiral fuse 3 centre channels 31, and the pressure that is provided by combustion air burns at mixing section 101 thorough mixing.Carry out the furnace roof igniting by the furnace top burning torch muzzle after use improving, all realize disposable igniting success, shortened furnace roof ignition time, igniting back burning torch stretches into that flare keeps not extinguishing in the stove.
