Abstract
The utility model relates to a sealing device for preventing smoke overflowing of steelmaking equipment, for resolving the problems of the prior art such as that the smoke hole has unreasonable angle, and the nitrogen gas can not restrain the ascending smoke, the smoke is easy to flow up to cause spark and hurt eyes and devices. The technical scheme is that the sealing device is composed of a sealing ring 1, a nitrogen gas inlet tube 2 and an exhaust hole 3 on the sealing ring 1, which is characterized in that the lower end of the sealing ring 1 is connected with a smoke damping tube 4 and the exhaust hole 3 is inclined. The sealing device can effectively prevent smoke overflow, to protect on-site devices and workers and avoid environment pollution, having simple operation.
Description
Technical field
The utility model relates to tightness system, more belongs to the excessive tightness system of flue gas that prevents steelmaking equipment.
Background technology
At present, in process for making, people are released in order to prevent desulfurization flue gas rifle hole under the desulfurization platform spray gun, have designed a circle shape nitrogen seal device, evenly be furnished with venting hole on this nitrogen seal device circle, direction is parallel to the ground, and after putting into operation, not only flue gas fails to seal, flue gas is scurried on very easily, and under the effect of gas blowby stream on the flue gas, Mars constantly spills, and very easily damages staff's eyes and burns out equipment.
The utility model content
It is unreasonable that the utility model is to solve the flue gas blowing angle of above-mentioned existence, nitrogen can not be to upwards flue gas generation compacting, flue gas is scurried on very easily, and under the effect of gas blowby stream on the flue gas, Mars constantly spills, very easily damage staff's eyes and burn out problem such as equipment, provide a kind of rational in infrastructure, effectively prevent the nitrogen seal device that flue gas is excessive that prevents that flue gas is excessive, the accident that prevents produces.
The technical measures that address the above problem:
Prevent the nitrogen seal device that flue gas is excessive, form that it is: be connected with the flue gas attenuator tube in the lower end of wear ring by the venting hole on wear ring, nitrogen inlet pipe, the wear ring; Venting hole is a tilted shape.
It is: venting hole tilts and to be: the tangent line angle of its hole wall and wear ring is that 70～15 °, the venting hole oblique angle that dips down is 45～70 ° and processes.
The utility model can prevent effectively that flue gas is excessive, thereby ensures field apparatus and workman's personnel safety, avoids contaminate environment, easily implements.
Description of drawings

Fig. 2 is a wear ring A-A sectional view among Fig. 1
Embodiment
Be further described below in conjunction with accompanying drawing:
Prevent the nitrogen seal device that flue gas is excessive: form by the venting hole 3 on wear ring 1, nitrogen inlet pipe 2, the wear ring (1).Processing venting hole 3 on wear ring 1, the tilted shape in its hole is: the tangent line angle of its hole wall and wear ring 1 is 70 °/60 °/30 °/15 °, venting hole 3 oblique angle that dips down is 45 °/55 °/60 °/70 ° and processes.In wear ring 1 lower end by the flue gas attenuator tube 4 that is threaded.
After high speed nitrogen enters wear ring 1 by nitrogen inlet pipe 2, penetrate to tangential direction and downward high speed by the wear ring 1 inboard venting hole 3 that gathers, in attenuator tube 4, form downward high-speed screw air-flow, thus string and realize preventing excessive purpose on the compacting flue gas.
Claims (2)
1. prevent the nitrogen seal device that flue gas is excessive, form, it is characterized in that: be connected with flue gas attenuator tube (4) in the lower end of wear ring (1) by the venting hole (3) on wear ring (1), nitrogen inlet pipe (2), the wear ring (1); Venting hole (3) is a tilted shape.
2. the nitrogen seal device that prevents that flue gas is excessive as claimed in claim 1 is characterized in that: venting hole (3) tilts and to be: the tangent line angle of its hole wall and wear ring (1) is that 70～15 °, excretory pore (3) oblique angle that dips down is 45～70 ° and processes.
