Abstract
The utility model provides a blast furnace gas step diffusing device, which comprises a blast furnace gas pipe network and a gas diffusing combustor and is characterized in that a group of diffusing pipes with different pipe diameter are arranged in parallel between the blast furnace gas pipe network and the gas diffusing combustor, a diffusing valve is arranged on each diffusing pipe, and each diffusing valve is electrically connected with a controlling and regulator through a wire. Under normal circumstances, gas diffusing volume can be controlled within a set range by means of automatic diffusing through the diffusing pipes with small pipe diameters, and waste of gas resource can be effectively avoided. Under abnormal conditions, gas can be automatically diffused through the diffusing pipes with large pipe diameters to increase gas diffusing volume, safety of the gas pipe can be ensured, and step diffusing of blast furnace gas is formed. By means of the blast furnace gas step diffusing device, the problem of gas resource waste caused by excessive diffusing of the existing gas diffusing device can be fundamentally resolved, safety of the blast furnace gas pipe network can be guaranteed, and remarkable economic efficiency can be brought to enterprises.
Description
Technical field
The utility model relates to a kind of bleeding device, and particularly a kind of blast furnace gas step bleeding device belongs to blast furnace ironmaking utility appliance technical field.
Background technology
Blast furnace can produce a large amount of blast furnace gases when ironmaking, will bring harm to gaspipe network in case blast furnace gas pressure is excessive.Therefore, need a part of blast furnace gas be discharged in the air,, ensure gaspipe network safety to reduce gas pressure by the coal gas diffusion device.Present Bleeding Device of Blast Furnace Gas adopts the bleeder of φ 1200mm substantially, though the bleeder of this diameter has higher emission effect when the discharging blast furnace gas, but owing to use the heavy caliber single tube to diffuse, and when valve regulating characteristic is in nonlinear area, can diffuse excessive coal gas because of circulation area is excessive.The rising of blast furnace gas system pipe network pressure that is to say when need be diffused, Controlling System starts bleeding device work, behind blast furnace gas pipeline network pressure recovery normal value, system sends instruction and closes bleeding device, it is excessive that can diffuse blast furnace gas this moment because of pipeline flow is excessive, causes the waste of blast furnace gas resource, adds that the regulate process time is long, very easily cause the vibration of Controlling System, jeopardize the blast furnace gas pipeline network security of system.Therefore be necessary prior art is improved.
Summary of the invention
Excessive for solving the bleeder diameter that has the employing of blast furnace bleeding device now, cause the amount of diffusing to be difficult to control, make blast furnace gas diffuse excessive and cause the coal gas wasting of resources, and regulate process is long and threaten problem such as blast furnace gas pipeline network security of system, and the utility model provides a kind of blast furnace gas step bleeding device.
The utility model is finished by following technical proposal: a kind of blast furnace gas step bleeding device, comprise blast furnace gas pipeline network and coal gas diffusion burner, it is characterized in that being arranged in parallel between blast furnace gas pipeline network and the coal gas diffusion burner bleeder group of different tube diameters, be equipped with on each bleeder and diffuse valve, respectively diffusing valve is electrically connected with control regulator by lead, so that the opening and closing number that diffuses valve on the bleeder is adjusted, so that control coal gas diffusion amount by control regulator.
Described bleeder group is arranged in parallel two at least, so that respectively the coal gas diffusion amount is carried out regulating and controlling.
The described bleeder caliber that is arranged in parallel is provided with from large to small, tubule footpath bleeder is as normal bleeder, automatically diffuse under the normal circumstances, to control the coal gas diffusion amount in setting range, avoid the coal gas wasting of resources, big caliber bleeder is as unusual bleeder, so that when appearance is unusual, increase the coal gas diffusion amount, guarantee gaspipe network safety.
The diameter of described tubule footpath bleeder is made as 300mm～500mm, and the diameter of big caliber bleeder is made as 600mm～800mm.
The utlity model has following advantage and effect: adopt such scheme, can be under normal circumstances, automatically diffuse by tubule footpath bleeder, the coal gas diffusion amount is controlled in the setting range, effectively avoids the waste of coal gas resource, simultaneously under abnormal conditions, automatically diffuse by big caliber bleeder, to increase the coal gas diffusion amount, guarantee gaspipe network safety, thereby the step that has formed blast furnace gas diffuses.Fundamentally solved existing coal gas diffusion device because of there being the excessive coal gas wasting of resources that causes of diffusing, guaranteed the safety of blast furnace gas pipeline network simultaneously, brought comparatively remarkable economic efficiency to enterprise.Be an ideal Bleeding Device of Blast Furnace Gas in fact.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
The blast furnace gas step bleeding device that the utility model provides, comprise blast furnace gas pipeline network 1 and coal gas diffusion burner 4, between blast furnace gas pipeline network 1 and coal gas diffusion burner 4, be arranged in parallel the bleeder group of different tube diameters, this bleeder group is two 3 and 6 that are arranged in parallel, wherein, bleeder 3 is the big caliber of 700mm, bleeder 6 is the little caliber of 400 mm, be respectively equipped with on the bleeder 3 and 6 and diffuse valve 2 and 5, diffusing valve 2 and 5 is electrically connected with control regulator 7 and 8 respectively by lead, as Fig. 1, under the normal circumstances, when the gas pressure of gaspipe network 1 surpasses set(ting)value, open diffusing valve 5 and carry out coal gas diffusion automatically on the bleeders 6 by control regulator 8, when the gas pressure of gaspipe network still continues to raise after valve 5 is diffused in unlatching, show and occur unusually, then diffuse valve 2 and diffuse automatically,, guarantee the safety of gaspipe network to increase the coal gas diffusion amount by control regulator 7 unlatchings.
