Abstract
The utility model relates to a device which is arranged on a spraying nozzle of blast furnace gas or converter gas on an industrial furnace to cause the combustion of the blast furnace gas or the converter gas stable. The utility model belongs to the technical field of the regulation or the control of the gas, wherein the utility model comprises a conical hollow shell and a cone on the center of the conical hollow shell. One to four blocking plates which are arranged along the circumference of the bottom surface of the cone are respectively connected and fixed with an outlet of the shell, and the upper conical surface of the cone passes through three to four baffle plates which are respectively connected and fixed with the shell along an axis direction. A stabilizer for blast furnace gas and converter gas of the utility model has simple structure. The utility model is sheathed on the outlet of a gas pipe of a combustor, a notch is generated by annular gas stream strand, and the outer air flows into the cone through the notch to create a negative-pressure return flow region on the center of the gas stream strand. Thus, the gas is mixed for combustion to form a stable ignition source and a function of stable combustion is played.
Description
Technical field
The utility model relates on the blast furnace gas or coal gas of converter nozzle that is installed on the industrial furnace, makes its combustion stablized a kind of device, belongs to the adjusting or the control technology field of combustion gas.
Background technology
When ordinary burner used blast furnace or coal gas of converter, because the main component of coal gas is CO, the flame propagation velocity after the burning was low, takes off fire easily at the burner place of burner, is not easy to form stable flame, and range of application is restricted.
The utility model content
The utility model provides a kind of simple in structure in order to overcome the defective of prior art, makes the blast furnace and the coal gas of converter flame holder of burner stable burning.
The utility model blast furnace and coal gas of converter flame holder are comprising the cone at conical hollow casing and its center; Be provided with 4 baffle plates of 1 ∽ around along the cone bottom surface and be connected and fixed with the outlet end of shell respectively, the taper seat on its top is connected and fixed with shell respectively along axis direction by 4 dividing plates of 3 ∽.
The utility model blast furnace and coal gas of converter flame holder, wherein hollow casing is that cylindrical shape or cylindrical shape and conical two parts connect and compose.
The utility model blast furnace and coal gas of converter flame holder, wherein cone is hollow or the filled circles cone.
The utility model blast furnace and coal gas of converter are simple in structure with flame holder, be sleeved in the gas pipe outlet of burner, make the coal gas stream burst generation " breach " of ring-type, by this " breach ", the negative pressure recirculating zone at the gas-flow thigh center that outer field air inflow cone causes, make coal gas mixed combustion, constitute stable incendiary source, play the effect of smooth combustion.
Description of drawings
Fig. 1 is a utility model blast furnace and coal gas of converter flame holder structural principle generalized section;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A generalized section of Fig. 2.
The specific embodiment
By Fig. 1～Fig. 3 as seen, the utility model blast furnace and coal gas of converter comprise the cone 2 at conical hollow casing 1 and its center with flame holder; Be provided with 4 baffle plates 3 around along the cone bottom surface and be connected and fixed with the outlet end of shell 1 respectively evenly distributedly, the taper seat on its top is provided with 4 dividing plates 4, is connected and fixed with shell 1 respectively evenly distributedly along axis direction.
During use, the inlet of shell 1 (being the awl tip of cone) is welded on the exit of gas-jet tube, and the passage that forms between the taper seat of coal gas by shell 1 inner surface and cone 2 outwards sprays, and mixes burning with shell 1 air stream outward.The coal gas stream plume of ring-type goes out, form the negative pressure recirculating zone in the cone bottom, because the coal gas stream stock-traders' know-how of ejection ring-type is crossed the barrier effect of the baffle plate 3 with certain width, make the coal gas stream thigh of ring-type produce " breach " 3 times at baffle plate, and outer field air flow through this " breach " enter the negative pressure recirculating zone at the coal gas stream burst center of ring-type, make coal gas and air mixed combustion, formed stable incendiary source, make this burner form stable flame, to satisfy the requirement of producing.
