The invention discloses a low-energy-consumption nitrogen sealing device which structurally comprises a pressure-stabilizing gas pocket and nitrogen blowing-injecting pipes. The pressure-stabilizing gas pocket is in a shape of an annular pipe and is arranged on the outside of a chute pipe body in a sleeving mode, multiple nitrogen blowing-injecting pipes are evenly arranged on one side of the pressure-stabilizing gas pocket in the peripheral direction and are arranged obliquely, one end of each nitrogen blowing-injecting pipe is communicated with the inner cavity of the pressure-stabilizing gas pocket, the other end of each nitrogen blowing-injecting pipe penetrates through the side wall of the chute pipe body and then extends to the inner cavity of the chute pipe body, a nitrogen leading-in pipe is further arranged on the pressure-stabilizing gas pocket, one end of the nitrogen leading-in pipe is communicated with the inner cavity of the pressure-stabilizing gas pocket, the other end of the nitrogen leading-in pipe is an external interface, the external interface is connected through a flange, and nitrogen leading of the nitrogen leading-in pipe is controlled through electrical interlocking. By adopting the annular pressure-stabilizing gas pocket, annular oblique-angle blowing, multi-point-position injection and other technologies, gas pressure is stably sealed, the chimney effect of a chute pipe is overcome, the sealing effect is improved, and the nitrogen using amount is reduced.
Description
Technical field
The present invention relates to a kind of sealing device, specifically low energy consumption nitrogen gas seal equipment.
Background technology
Converter steelmaking process is accompanied by the chemical reaction of series of complex, in process, needs by the elephant trunk that feeds intakeAdd the raw materials such as ore, alloy, lime, fluorite, and interior produce inflammable as what lead taking coal gas of converter of stovePernicious gas, as can not get effective control, will upwards be discharged along elephant trunk, cause air pollution, suffocate,The accidents such as blast. Many methods that are filled with medium pressure nitrogen gas in elephant trunk avoid pernicious gas to enter elephant trunk at present,But consumption is larger, increase enterprise's production cost.
Summary of the invention
The object of the present invention is to provide low energy consumption nitrogen gas seal equipment, this annular voltage stabilizing gas bag, circular slantingThe technology such as angle is blown into, multi-point injection, stabilized seal gas pressure, overcomes elephant trunk stack effect, improvesSealing effectiveness, reduces nitrogen use level.
The present invention solves the technical scheme that its technical problem takes: low energy consumption nitrogen gas seal equipment, itsStructure comprises that voltage stabilizing gas bag and nitrogen blow and penetrates pipe, described voltage stabilizing gas bag tubulose ringwise, and voltage stabilizing gas bag is nested withIn the outside of elephant trunk body, described voltage stabilizing gas bag one side circumferencial direction is evenly provided with multiple nitrogen and blows and penetrate pipe,Described nitrogen blows to be penetrated pipe and is obliquely installed, and nitrogen blows one end of penetrating pipe and communicates with voltage stabilizing gas bag inner chamber, the other endExtend to elephant trunk chamber body through after elephant trunk body sidewall, on described voltage stabilizing gas bag, be also provided with nitrogen and introducePipe, one end of described nitrogen inlet tube communicates with voltage stabilizing gas bag inner chamber, the other end is external tapping, described outsideInterface connects by flange, and the nitrogen of described nitrogen inlet tube is introduced by electrical interlocks control.
Further, the side of described voltage stabilizing gas bag is evenly provided with four nitrogen and blows and penetrate pipe, and each root nitrogen blowsThe setting angle of penetrating pipe becomes miter angle with the axis of elephant trunk body.
Further, described voltage stabilizing gas bag is that the seamless boiler vessel pipe that diameter is not less than φ 80mm is processed into ringShape, and bending diameter is greater than elephant trunk written or printed documents external diameter 200mm.
Further, described nitrogen blows penetrates pipe for φ 30mm seamless pipe, and nitrogen inlet tube diameter is φ 38mmSeamless pipe.
The invention has the beneficial effects as follows:
1, sealing device blows and penetrates pipe by nitrogen is set on voltage stabilizing gas bag, and voltage stabilizing gas bag can make each nitrogenAir-blowing exit point pressure stability, the stable nitrogen-sealed layer of mineralization pressure in elephant trunk body. Because nitrogen blowsPenetrate pipe and be 45 degree with elephant trunk body axis, can be blown into nitrogen along direction 45 degree that feed intake, make sealant orientedUnder pressure, interruption-forming injection effect under elephant trunk, has overcome the stack effect of long elephant trunk. Multi-point sprayTechnology can improve sealant density of nitrogen, prevents that air from sneaking into.
2, because the nitrogen of nitrogen inlet tube is introduced by electrical interlocks control, realized nitrogen-sealed and openedClose and smelting operation Synchronization Control, avoid the non-energy resource consumption duration of heat, remarkable in economical benefits.

Detailed description of the invention
With reference to Figure of description, low energy consumption nitrogen gas seal equipment of the present invention is described in detail below.
As shown in Figure 1, Figure 2, Figure 3 shows, low energy consumption nitrogen gas seal equipment of the present invention, its structure comprisesVoltage stabilizing gas bag 2 and nitrogen blow penetrates pipe 3, described voltage stabilizing gas bag 2 tubulose ringwise, and voltage stabilizing gas bag 2 is nested withThe outside of elephant trunk body 1, described voltage stabilizing gas bag 2 one side circumferencial directions be evenly provided with multiple nitrogen blow penetrate pipe 3,Described nitrogen blows to be penetrated pipe and 3 is obliquely installed, and nitrogen blows one end of penetrating pipe 3 and communicates with voltage stabilizing gas bag 2 inner chambers,The other end extends to elephant trunk chamber body through after elephant trunk body 1 sidewall, on described voltage stabilizing gas bag 2, also establishesHave nitrogen inlet tube 4, one end of described nitrogen inlet tube 4 communicates with voltage stabilizing gas bag 2 inner chambers, and the other end isExternal tapping, described external tapping connects by flange, and the nitrogen of described nitrogen inlet tube 4 is introduced by electricChain control.
The side of described voltage stabilizing gas bag 2 be evenly provided with four nitrogen blow penetrate pipe 3, each root nitrogen blows penetrates pipeSetting angle become miter angle with the axis of elephant trunk body 1.
Described voltage stabilizing gas bag is that the seamless boiler vessel pipe that diameter is not less than φ 80mm is processed into annular, and curvedRight and wrong footpath is greater than elephant trunk written or printed documents external diameter 200mm.
Described nitrogen blows penetrates pipe for φ 30mm seamless pipe, and nitrogen inlet tube diameter is φ 38mm seamless pipe.
Blow and penetrate pipe and blow radio-nitrogen gas to elephant trunk chamber body, voltage stabilizing gas by four nitrogen on voltage stabilizing gas bagBag can make each nitrogen blow exit point pressure stability, the stable nitrogen-sealed layer of mineralization pressure in elephant trunk body.Be 45 degree because nitrogen blows to penetrate to manage with elephant trunk body axis, can be blown into nitrogen along direction 45 degree that feed intake, makeSealant has downward pressure, and interruption-forming injection effect under elephant trunk has overcome the stack effect of long elephant trunk.Multi-point spray technique can improve sealant density of nitrogen, prevents that air from sneaking into. Nitrogen inlet tube is by electricChain control air feed, has realized nitrogen-sealed keying and smelting operation Synchronization Control, avoids the non-duration of heatEnergy resource consumption, remarkable in economical benefits.
