Abstract
The utility model relates to a semi-closed smoke collecting hood of a volume type for a refining furnace, which is composed of two or more than two movable or fixed semi-closed smoke collecting hoods, wherein, the position of each of the semi-closed smoke collecting hoods is arranged at the upper side of a working platform of the refining furnace, and the semi-closed smoke collecting hood of a volume type and a refining furnace cover have no mechanical connection. The original smoke collecting hood of a furnace cover type is changed into the combination of the semi-closed smoke collecting hoods which can be moved and are separated from the refining furnace cover and are arranged at the upper side of the working platform of the refining furnace. The utility model is characterized in that the produce operation of the refining furnace is convenient, and meanwhile, the mode that smoke is pumped in close range from the lower side of the furnace cover is changed into the mode that the smoke is pumped by using smoke heat power at the upper side of the refining furnace. Thus, the efficiency of removing dust is enhanced, the energy consumption is reduced, and the operation environment of making steel is improved.
Description
Refining furnace positive displacement semi-hermetic exhaust fume collecting hood belongs to cleaner, relates to HVAC, electric furnace, dedusting technology field.
In the electric furnace steel making production process, the collection of flue dust discharging is one of important step in the production technology.It must meet two principles in real work: the one, collect the waste gas of discharging in the stove as much as possible, and the 2nd, do not influence production operation, do not influence the physical-chemical reaction in the smelting process.
The method that refining furnace is collected flue dust now is to cover at refining furnace a steam vent is set, and waste gas discharges to blast pipe outward through steam vent.Such smoke collecting device has three shortcomings: the one, can not collect the waste gas in the stove fully, when needing to open operations such as the refining bell feeds intake in the smelting process, waste gas with regard to loss in the four directions, workshop; The 2nd, steam vent is very near from burner hearth, tends to slag or foam are sucked smoke discharging pipe; The 3rd, workman's inconvenient operation.
The purpose of this utility model is: propose a kind of improvement project at above problem, make the refining furnace fume extractor into positive displacement semi-hermetic exhaust fume collecting hood removable, that be located at workbench top, separate with the refining bell, improve smoke collecting efficiency by this scheme, improve the production environment of refining furnace.
The concrete scheme of the utility model is as follows:
Refining furnace positive displacement semi-hermetic exhaust fume collecting hood is made up of two or two above semi-hermetic exhaust fume collecting hoods (1), and semi-hermetic exhaust fume collecting hood (1) is by fixedly petticoat pipe (10) or mobile petticoat pipe (11) are formed.Semi-hermetic exhaust fume collecting hood (1) is located at the top of workbench (4), and does not have the machinery connection between refining bell (3); Positive displacement semi-hermetic exhaust fume collecting hood (1) highly 〉=1.8m, its exhanst gas outlet is located at side or top.
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 the utility model operation principles are described: the flue gas in refining furnace (2) production process is overflowed from the venthole (14) of refining bell (3), or overflow from electrode patchhole (9), the heat power of utilization itself rises, vacuum suction by in the semi-hermetic exhaust fume collecting hood (1) enters fixedly flue (7) or movable flue (6).Semi-hermetic exhaust fume collecting hood (1) can be made up of fixedly petticoat pipe (10) or mobile petticoat pipe (11), and mobile petticoat pipe (11) can be gone up at track (5) and move, and is convenient to the STEELMAKING PRODUCTION operation.When refining bell (3) when opening, utilize the flue gas of flue gas heat power refining furnace (1) to be inhaled in the positive displacement semi-hermetic exhaust fume collecting hood.Because positive displacement semi-hermetic exhaust fume collecting hood is located at the top of workbench (4), and there is not the machinery connection between refining bell (3), so can not suck flue to scum silica frost in the electric furnace and foam.
Below in conjunction with explanation of a pair of enforcement of accompanying drawing.
Embodiment one: semi-hermetic exhaust fume collecting hood (1) is made up of two mobile petticoat pipes (11) among the embodiment one, according to producing the needs partable, in mobile petticoat pipe (11) top movable flue (6) is arranged.Semi-hermetic exhaust fume collecting hood (1) is a vault arc cover among the embodiment one, pulley (12) has been installed below so that go up mobile at track (5).
Below in conjunction with two pairs of embodiment two explanations of accompanying drawing.
Embodiment two; Fixedly form by petticoat pipe (10) and two mobile petticoat pipes (11) by one for semi-hermetic exhaust fume collecting hood (1) among the embodiment two, fixedly flue (7) is located at the fixedly side of petticoat pipe (10), semi-hermetic exhaust fume collecting hood (1) among the embodiment two is the trapezoidal cover of flat-top, highly is 2m.
In accompanying drawing 1 and the accompanying drawing 2 to mark the digital number meaning as follows: (1) semi-hermetic exhaust fume collecting hood, (2) refining furnace, (3) refining bell, (4) workbench, (5) track, (6) movable flue, (7) fixing flue, (8) electrode, (9) electrode patchhole, (10) are petticoat pipe fixedly, (11) mobile petticoat pipe, (12) pulley, (13) flue gas stream, (14) bell venthole.
Description of drawings:
Accompanying drawing 1 is made of the work schematic diagram of semi-hermetic exhaust fume collecting hood (1) 2 mobile petticoat pipes (11).
Fixedly petticoat pipe (10) and 2 mobile petticoat pipes (11) are formed the work schematic diagram of semi-hermetic exhaust fume collecting hood (1) to accompanying drawing 2 by 1.
Claims (1)
1, refining furnace positive displacement semi-hermetic exhaust fume collecting hood is characterized in that: be made up of two or two above semi-hermetic exhaust fume collecting hoods (1), the position of semi-hermetic exhaust fume collecting hood (1) is for fixing or movably;
Semi-hermetic exhaust fume collecting hood (1) is located at the top of workbench (4), does not have machinery between semi-hermetic exhaust fume collecting hood (1) and refining furnace bell (3) and connects;
Height 〉=the 1.8m of semi-hermetic exhaust fume collecting hood (1); Its exhanst gas outlet is located at top or side.
