Abstract
The utility model discloses a quick extinguishing device of rolling mill exhaust emission flue, including more than one fire alarm probe, install automatic alarm subassembly in the master -control room, be equipped with a main tributary and the ramose nitrogen gas branch pipe of more than one, second nitrogen gas hose, check valve, quick -operation joint, first nitrogen gas hose, valve switch and nitrogen gas collecting main, each fire alarm probe is installed respectively in the not same district of rolling mill flue section, and its output connects the corresponding input of automatic alarm subassembly respectively, the not same district section of each branch intercommunication rolling mill flue of nitrogen gas branch pipe, main tributary in proper order through check valve, second nitrogen gas hose quick -operation joint, first nitrogen gas hose, valve switch intercommunication nitrogen gas collecting main. It can in time discover the conflagration in the rolling mill waste gas flue, eliminates conflagration in the rolling mill waste gas flue in the initial phase, prevents fire spreading, retrieves great amount economic loss. It adopts nitrogen extinguishing, does not have any influence to equipment.
Description
Technical field
The utility model relates to a kind of fast fire-extinguishing apparatus of milling train toxic emission flue, belongs to cold rolling mill fire-proofing security technologies field.
Background technology
The cold rolling rolling mill practice belonging to high added value, high technology content in iron and steel production.In order to the heat that the rolling of control cincture steel technological parameter simultaneously stability produces, need to spray a large amount of emulsions in the milling train course of work, the effect of lubrication, cooling can be played.Emulsion is by ROLLING OIL, water, the mixing material that merges according to a certain percentage with other media a small amount of.In mill milling process, a large amount of air-fuel mixture gas of emulsion volatilization effusion, these waste gas are taken away by the flue of smoke exhaust fan above milling train, are released into air after filtering to workshop outside.This toxic emission flue is generally arranged on the high-altitude of above milling train more than ten meter, and diameter is mostly 4 ~ 10 meters, and length can reach tens meters, and centre all seals, and belongs to the typical confined space.Emulsion EGT is very high, is cooling gradually, be attached to flue inner wall through flue, is agglomerated into greasy filth, fluid.Therefore, the fire risk of milling train toxic emission flue is very high, and the flue condition of a fire not easily finds.Flue aloft personnel is difficult to close, and flue, once breaking out of fire meeting rapid spread, involves the expensive equipments such as milling train, almost cannot put out a fire to save life and property.Domestic had a lot of cold rolling mill flue to catch fire, and tandem mill body equipment of igniting, causes the case of the huge loss of several hundred million unit.The fire-fighting technique of milling train flue becomes a difficult problem anxious to be cracked.
Utility model content
The technical problems to be solved in the utility model is to provide the fast fire-extinguishing apparatus of simple, the easy to operate milling train toxic emission flue of a kind of structure.
Technical solution adopted in the utility model is:
Comprise more than one fire alarm probe, automatic alarm assembly, be provided with a master prop up and one with the nitrogen arm of top set, the second nitrogen flexible pipe, non-return valve, snap joint, the first nitrogen flexible pipe, valve switch and nitrogen main composition;
Described each fire alarm probe is arranged on the different sections of milling train flue respectively, and its output connects the respective input of described automatic alarm assembly respectively; Described automatic alarm assembly is arranged in master-control room;
Each branch of described nitrogen arm 2 is communicated with from the different sections of described milling train flue respectively, and non-return valve described in its main Zhi Jing is communicated with described second nitrogen flexible pipe; Described second nitrogen flexible pipe is communicated with described first nitrogen flexible pipe through described snap joint; Described first nitrogen flexible pipe is communicated with described nitrogen main through described valve switch.
Be provided with a master in described nitrogen arm to prop up and Liang Ge branch, described fire alarm probe is two.
The beneficial effect adopting technique scheme to produce is:
1, the utility model can fire in Timeliness coverage milling train waste gas flue, eliminates fire in milling train waste gas flue in the initial phase very soon, stops fire spread, retrieves great economic loss.
2, the utility model adopts iron and steel factory to be easy to gas medium---the nitrogen extinguishing obtained, and can not leave any vestige, have no effect to equipment.

Detailed description of the invention
Embodiment 1:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a fast fire-extinguishing apparatus for milling train toxic emission flue, comprise more than one fire alarm probe 1, automatic alarm assembly 10, be provided with a master prop up and one form with nitrogen arm 2, the second nitrogen flexible pipe 4 of top set, non-return valve 3, snap joint 5, first nitrogen flexible pipe 6, valve switch 7 and nitrogen main 8;
Described each fire alarm probe 1 is arranged on the different sections of milling train flue 9 respectively, and its output connects the respective input of described automatic alarm assembly 10 respectively; Described automatic alarm assembly 10 is arranged in master-control room;
Each branch of described nitrogen arm 2 is communicated with from the different sections of described milling train flue 9 respectively, and non-return valve 3 described in its main Zhi Jing is communicated with described second nitrogen flexible pipe 4; Described second nitrogen flexible pipe 4 is communicated with described first nitrogen flexible pipe 6 through described snap joint 5; Described first nitrogen flexible pipe 6 is communicated with described nitrogen main 8 through described valve switch 7.
Be provided with a master in described nitrogen arm 2 to prop up and Liang Ge branch, described fire alarm probe 1 is two.
Nitrogen causes near milling train flue 9 by nitrogen main 8, and each branch of nitrogen arm 2 is responsible for nitrogen being passed into respectively each section of flue.Snap joint 5 disconnects under normal circumstances, and valve switch 7 is closed.If there is the condition of a fire in flue, fire alarm probe 1 detects that the condition of a fire occurs in flue 9 inside, triggers automatic alarm assembly 10 in master-control room and sends alarm signal, operator on duty finds alarm signal, to stop power-off at once, send someone snap joint 5 to couple together, then open valve switch 7.Nitrogen in nitrogen main 8, is full of rapidly the inner space of milling train flue 9, flare is suffocated, stamps out a fire through the first nitrogen flexible pipe 6, second nitrogen flexible pipe 4 and nitrogen arm 2.
Through repeatedly drilling, passing into flue to nitrogen only need 1 ~ 2 minute from the master-control room signal that receives the report for police service.
