Abstract
The utility model relates to a LF refining furnace dust collector, including setting up dust removal house steward and the dust exhausting fan on the LF refining furnace, it collects the cover to be fixed with the flue gas on the dust removal house steward, the side that the cover was collected to the flue gas is equipped with cleaning tube, the last dust removal valve that is equipped with of cleaning tube. The utility model discloses can be according to the switching of on -the -spot operating condition automatic control dust removal valve, for dust exhausting fan automatic speed adjustment, when avoiding environmental pollution, can be energy -conserving for energy saving and consumption reduction provides the condition, it is extravagant to reduce the energy. The utility model discloses of a tightly knit structure, rationally distributed, convenient to use and cost of manufacture are low, can satisfy the demand and develop the market demand of this work.
Description
Technical field
The utility model relates to a kind of cleaning apparatus, and a kind of cleaning apparatus for LF refining furnace, belongs to steel-making technical field of environment protection equipment specifically.
Background technology
At present, LF purifying method in steelmaking process, its principal feature adopts the method for ladle bottom blowing argon gas that molten steel is obtained to stir kinetic energy, and there is good desulfating and deoxidation effect same with induction stirring, be more conducive to middle inclusion floating, because ladle argon-blown technology is simpler and easily operate than electromagnetic mixing apparatus, facilitate the rapid popularization of LF technology.This LF purifying method refining unit used is called LF refining furnace.
But LF refining furnace can produce a large amount of high-temperature dusty gas in process of production, make the requirement that cannot meet national project construction, not only affect the safety and Health of laborer, huge pollution is also caused to surrounding enviroment simultaneously.At present, the smoke discharging dust removing system for LF refining furnace is mainly workshop access dedusting house steward, rear access fly-ash separator.General cleaning shaft is only equipped with manually-operated gate, and this manually-operated gate is only closed in the maintenance period, and all the other times open always, no matter whether produce load of dust remove and exist always, inevitably cause the long-term heavy-duty service of dedusting fan, cause energy dissipation.
Utility model content
The defect that the utility model exists for prior art, proposes a kind of reasonable in design, easy to use, good dedusting effect, and the LF refining furnace cleaning apparatus can avoiding energy dissipation.
The purpose of this utility model, a kind of LF refining furnace cleaning apparatus is provided, comprises and be arranged on dedusting house steward on LF refining furnace and dedusting fan, described dedusting house steward is fixed with smoke collecting cover, the side of described smoke collecting cover is provided with cleaning shaft, and described cleaning shaft is provided with dust removing valve.
The technical scheme that the utility model limits further is: aforesaid LF refining furnace cleaning apparatus, the import of cleaning shaft is corresponding with the exhanst gas outlet of smoke collecting cover.
Further, aforesaid LF refining furnace cleaning apparatus, smoke collecting cover is water cooling smoke collecting hood, comprises fume pipe and collecting hood, and the top of collecting hood is fixed in the air outlet of fume pipe, and inlet mouth is connected with dedusting house steward; Collecting hood is rounded.
Further, aforesaid LF refining furnace cleaning apparatus, dust removing valve is electrical dust-removing valve or pneumatic dust collection valve.
Further, aforesaid LF refining furnace cleaning apparatus, dust removing valve is connected by the control end of circuit with the PLC control device of LF refining furnace.
Outstanding effect of the present utility model is: the utility model can control the opening and closing of dust removing valve automatically according to on-the-spot actual condition, be dedusting fan automatic speed regulation, while avoiding environmental pollution, energy-conservationly can provide condition for energy-saving and cost-reducing, reduce energy dissipation.
The utility model is of a tightly knit structure, rationally distributed, easy to use and cost of manufacture is low, can satisfy the demand and carry out the market requirement of this work.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Embodiment
Embodiment
Originally executing the PLC control device used in example is existing LF refining furnace control device, for: Siemens S7-400, Rockwell ControlLogix series.
A kind of LF refining furnace cleaning apparatus that the present embodiment provides, structure as shown in Figure 1, comprise LF refining furnace 4, this LF refining furnace is provided with dedusting house steward 2 and dedusting fan, dedusting house steward is fixed with water cooling smoke collecting hood 1, the side of smoke collecting cover is provided with cleaning shaft 3, the import of this cleaning shaft is corresponding with the exhanst gas outlet of smoke collecting cover, smoke collecting cover is water cooling smoke collecting hood, comprise fume pipe and collecting hood, the top of collecting hood is fixed in the air outlet of fume pipe, and inlet mouth is connected with dedusting house steward; Collecting hood is rounded.
Cleaning shaft is provided with dust removing valve, and this dust removing valve is electrical dust-removing valve or pneumatic dust collection valve.And dust removing valve is connected by the control end of circuit with the PLC control device of LF refining furnace.
During the present embodiment work, first, when LF refining furnace is produced, the dust removing valve be installed on cleaning shaft is automatically opened under the effect of PLC control device, and automatically regulate the rotating speed of dedusting fan, high-temperature smoke is sucked by water cooling smoke collecting hood, and is discharged by dedusting house steward.When LF refining furnace is except at the end of 1 stove liquid steel refining, is automatically closed the dust removing valve on cleaning shaft by PLC control device, so both can ensure dust removing effects, again for realizing the automatic speed regulation of dedusting fan, energy-saving and emission-reduction lay a good foundation.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
