The utility model discloses the realization improves dust removal effect according to the aperture of converter operating mode automatic control converter secondary dust removal valve to for dust exhausting fan automatic speed adjustment, energy saving and consumption reduction provide the condition, it is extravagant to reduce the energy.
Description
Technical field
The utility model relates to a kind of secondary BOF dedusting system device, belongs to steelmaking technical field.
Background technology
Converter can produce a large amount of flue dust in process of production, except the flue dust that primary dedusting system extracts, at hot metal charging, a large amount of secondary smokes all can be overflowed around fire door in processes such as blowing and tap and slag tap, severe contamination environment and jeopardize the healthy of staff, in order to ensure normal production, improve the Working environment in workshop, present converter steelmaking workshop generally can be provided with secondary dedusting system, and several converter shares a set of secondary dedusting system, it is obviously not enough that fly-ash separator resistance undermines pipeline of dust collector suction, dust removing effects is poor, smoke of steel factory environmental improvement DeGrain.In addition, the aperture of converter dust-removing valve is all generally undertaken controlling or taking Non-follow control by blowing and tapping two situation kinds at present, and can not adjust aperture in time by converter actual condition, dust removing effects is difficult to ensure, the long-term heavy-duty service of dedusting fan, causes energy dissipation simultaneously.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of good dedusting effect, avoids the secondary BOF dedusting system device of reentrainment of dust and pollution surrounding environment.
In order to solve above technical problem, the utility model provides a kind of secondary BOF dedusting system device, comprise PLC control device, stokehold dedusting gate cover, main suction hood and dedusting house steward after stove, described stokehold dedusting gate cover is connected respectively at dedusting house steward with suction hood main after stove, also comprise the smoke collecting cover being arranged on converter furnace roof, described smoke collecting cover is connected with cleaning shaft, described cleaning shaft be arranged on the cleaning shaft after stove and be connected, described cleaning shaft and cleaning shaft are separately installed with dust removing valve, described cleaning shaft is connected with dedusting house steward simultaneously, described PLC control device and dust removing valve connection.
The technical scheme that the utility model limits further is:
Further, described cleaning shaft is connected by pipe connecting with cleaning shaft.
Further, the cleaning shaft before each Converter is symmetrical two, and every root cleaning shaft is separately installed with dust removing valve.
Further, the dust removing valve on two described cleaning shafts is connected with cleaning shaft by pipe connecting.
Further, described dust removing valve is adjustment type dust removing valve.
Further, the open range of opening of the dust removing valve on described cleaning shaft is 0%-100%.
The beneficial effects of the utility model are: the utility model realizes the aperture automatically controlling secondary BOF dedusting system valve according to converter operating mode, improves dust removing effects, reduces the wasting of resources, and for dedusting fan automatic speed regulation, energy-saving and cost-reducingly provide condition.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
embodiment 1
A kind of secondary BOF dedusting system device that the present embodiment provides, as shown in Figure 1: comprise PLC control device, stokehold dedusting gate cover, main suction hood and dedusting house steward after stove, stokehold dedusting gate cover is connected respectively at dedusting house steward with suction hood main after stove, also comprise the smoke collecting cover 5 being arranged on converter 1 furnace roof, smoke collecting cover 5 is connected with cleaning shaft 2, cleaning shaft 2 be arranged on the cleaning shaft after stove 3 and be connected, cleaning shaft 2 and cleaning shaft 3 are separately installed with dust removing valve 4, cleaning shaft 3 is connected with dedusting house steward simultaneously, PLC control device and dust removing valve connection.
Cleaning shaft 2 is connected by pipe connecting with cleaning shaft 3.The open range of opening of the dust removing valve 4 on cleaning shaft 2 is 0%-100%.Dust removing valve 4 on two cleaning shafts 2 is connected with cleaning shaft 3 by pipe connecting.Dust removing valve 4 is adjustment type dust removing valve.Cleaning shaft 2 before each Converter is symmetrical two, and every root cleaning shaft 2 is separately installed with dust removing valve 4.
During utility model works, when converter starts hot metal charging, be now arranged on dust removing valve 4 on stokehold cleaning shaft 2 under the effect of PLC control device, according to actual dust removing effects open to maximum opening I as: 80%; At the end of converter hot metal charging, according to actual dust removing effects by PLC control device regulate be arranged on dust removing valve 4 on stokehold cleaning shaft 2 to middle aperture II as: 30%, adjust simultaneously dust removing valve 4 to maximum opening on cleaning shaft 3 as: 80%; After converter starts tapping, PLC control device close simultaneously be arranged on dust removing valve 4 on stokehold cleaning shaft 2 to minimum aperture II as: 20%; At the end of converter tapping, PLC control device cuts out the forward and backward dust removing valve of stove to minimum aperture automatically as 20%, completes the aperture that the utility model realizes automatically controlling according to converter operating mode secondary BOF dedusting system valve thus, realizes the automatic red-tape operati of final dusting.Make dust removing effects to improve more than 20%, decrease the pollution of environment, simultaneously for realizing the automatic speed regulation of dedusting fan, energy-saving and emission-reduction lay a good foundation.The PLC control device of this technical solution utilizes existing converter control system to realize, and as Siemens S7-400, Rockwell ControlLogix series etc., do not need to increase extra investment.
In addition to the implementation, the utility model can also have other embodiments.Behind such as stokehold, the aperture of dust removing valve can be determined according to the actual dust removing effects in converter producing each stage, 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.
