Abstract
The utility model provides a blast-furnace gas safe diffusion device which comprises a gas pipe network, wherein one end of the gas pipe network is connected with a blast-furnace gas pipe network, and the other end is connected with each gas user; the gas pipe network is connected with a gas diffusion burner through a diffusion pipe group with a control valve; and the blast-furnace gas safe diffusion device is characterized in that a third diffusion pipe with a control valve is arranged between the gas pipe network and the gas diffusion burner. Through the utility model, the gas leakage can be effectively avoided, the gas diffusion amount is reduced, the recycled amount is increased, and the gas energy is saved; under the same pressure, a diffusion pipe diffuses the gas first; when the pressure rises, another diffusion pipe is automatically opened for diffusion to increase the diffusion amount and guarantee the safety of the gas pipe network; and meanwhile, the regulation is convenient, and the leakage is reduced. When an accident happens to the gas user, for example, the pressure of the gas system jumps suddenly due to the load shedding of a generator and the emergency shut-down of a steel-making heating furnace, the diffusion of a third diffusion pipe is added so as to ensure stable pressure of the gas pipe network.
Description
Technical field
The utility model relates to a kind of bleeding device, and especially a kind of blast furnace gas safety bleeding device belongs to blast furnace ironmaking utility appliance technical field.
Background technology
There is following problem in present bleeding device: (1) can't be in time, exactly coal gas is diffused, and easily ductwork pressure caused fluctuation, and then influence the other system ordinary production.(2) often appearance can only manually be diffused and mechanical stuck phenomenon, causes ductwork pressure too high, and pressure signal does not in time show, pipe network is not diffused, thereby causes gas leak, exists bigger potential safety hazard.(3) can't in time close, so the coal gas diffusion amount can't be effectively controlled, increase the coal gas diffusion rate simultaneously, cause the waste of coal gas resource diffusing valve.(4) in case a certain user's fault, to diffuse and regulate untimelyly, pressure surge is bigger, usually is responsible for superpressure because of blast furnace gas and causes gas leak.Therefore, be necessary prior art is improved.
Summary of the invention
The purpose of the utility model is to provide a kind of blast furnace gas safety bleeding device, to regulate blast furnace gas pipeline network pressure automatically in good time, ensures safety in production, and reduces the waste of coal gas resource.
The utility model provides a kind of like this blast furnace gas safety bleeding device, comprises gaspipe network, and this gaspipe network one end links to each other with blast furnace gas pipeline network; The other end links to each other with each coal gas user, and gaspipe network links to each other with the coal gas diffusion burner through the bleeder group of band valve on it, it is characterized in that being provided with between gaspipe network and the coal gas diffusion burner the 3rd bleeder of band valve on it; So that according to the gaspipe network pressure surge; Through bleeder group and the 3rd bleeder, adjust in good time, both guaranteed safety in production; Do not enlarge the coal gas diffusion amount again, practice thrift the coal gas resource.
Said coal gas diffusion pipe group is set up in parallel many, and each root bleeder is provided with valve, and each valve is electrically connected with control regulator through lead.
Valve on said the 3rd bleeder is electrically connected with control regulator through lead.
The utility model compared with prior art has advantage and effect: adopt such scheme, effectively stopped gas leakage, reduced the coal gas diffusion amount simultaneously; Increase yield, practice thrift the coal gas energy, under same pressure; Diffuse by a bleeder earlier, when increased pressure, open another bleeder automatically and diffuse, with the increase amount of diffusing; Ensure gaspipe network safety, convenient simultaneously the adjusting reduced leakage loss.When coal gas user burst accident, like the generator removal of load, the urgent blowing out of steel-making process furnace causes coal gas system pressure when moment raises suddenly; Increase diffusing of the 3rd bleeder again; Guarantee the gaspipe network pressure-stabilisation, reduce the gas leak amount, improve the coal gas comprehensive utilization ratio.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described.
Like Fig. 1, the blast furnace gas safety bleeding device that the utility model provides comprises gaspipe network 5; These gaspipe network 2 one ends link to each other with blast furnace 3 gas pipes, and the other end links to each other with the coal gas user, and the coal gas user comprises user 1, steel-making process furnace user 15, the industrial gas storage cabinet 14 with gas to generate electricity; Gaspipe network 2 links to each other with coal gas diffusion burner 9 through the bleeder group 4,8 of band valve 5,6,7 on it; Also be provided with the 3rd bleeder 10 of band valve 11,12,13 on it between gaspipe network 2 and the coal gas diffusion burner 9, so that according to gaspipe network 2 pressure surges, through bleeder group 4,8 and the 3rd bleeder 10; Adjust in good time; Both guarantee safety in production, do not enlarged the coal gas diffusion amount again, practiced thrift the coal gas resource; It is two that said coal gas diffusion pipe group 4,8 is set up in parallel, and first bleeder 4 is provided with butterfly valve 5, blank-plate valve 6, motor-driven control valve 7, the second bleeders 8 and is provided with motor-driven control valve 7, and each valve is electrically connected with control regulator through lead; Valve on said the 3rd bleeder 10 is made as butterfly valve 13, blank-plate valve 12, motor-driven control valve 11, and each valve is electrically connected with control regulator through lead.
