Abstract
The utility model provides a converter rear tapping dedusting device, which comprises a dust absorbing cover, a wind pipe, a valve and a secondary dedusting pipeline, wherein the dust absorbing cover is hung below a converter rear operating platform, one end of the wind pipe is connected with the dust absorbing cover, the other end is connected with the secondary dedusting pipeline, and the valve is arranged on the wind pipe. The valve is automatically opened before a converter taps, smoke produced when the converter taps is absorbed to the dust absorbing cover, and enters the secondary dedusting pipeline along the wind pipe. The converter rear tapping dedusting device has the advantages and effects that the structure of the device is simple and practical, the investment is less, the efficiency is high, the maintenance is simple, and the fault rate is extremely low.
Description
Technical field
The utility model relates to the dedusting field of converter, specifically is a kind of dust removal installation when being applied to behind the converter stove tapping.
Background technology
At present, when tapping behind the domestic and international large and medium-sized converter stove, generally adopt below service platform behind the stove and a baffle plate is set near the converter position, the flue dust major part that produces during converter tapping enters in the converter tightness system, a part enters under the stove in the slag road, the flue dust that enters in the converter tightness system is siphoned away by stokehold final dusting pipeline, enters that the flue dust in the slag road can't be processed under the stove, and surrounding environment is polluted.
Summary of the invention
The utility model provides the dust removal installation of tapping behind a kind of converter stove, and the flue dust that produces when converter tapping is all siphoned away by the final dusting system pipeline, has solved the problem that prior art pollutes surrounding environment.
The utility model is that a dust hood, two branch wind pipes and two valves are set below service platform behind the converter stove.Dust hood is hung under service platform behind the converter stove near the converter tapping position.Two branch wind pipes, one end is connected with dust hood respectively, and an other end joins with the final dusting pipeline respectively.A valve is installed on every branch wind pipe, and the switch signal of this valve enters PLC, can realize the switch of Long-distance Control valve.When tapping was prepared in converter, valve was opened automatically, and a flue dust part that produces during converter tapping is siphoned away by the final dusting pipeline of converter stokehold, and a part is inhaled into behind the converter stove in the dust excluding hood, and flue dust is in airduct enters the final dusting pipeline.The flue dust that produces during converter tapping is all siphoned away by the secondary BOF dedusting system system.When tapping finished, valve was closed automatically.
Advantage of the present utility model and effect are, owing to adopted the scheme that dust excluding hood and airduct are installed near the converter tapping position under stove rear converter service platform, flue dust excessive during converter tapping is all sucked in the final dusting pipeline, has solved problem of environmental pollution.Characteristics such as this dust removal installation has that equipment is simple and practical, less investment, efficient height, Maintenance free, failure rate are low.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model equipment;
Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is elaborated.
As shown in Figure 1, the tapping dust removal installation mainly comprises dust hood 1, airduct 2, airduct 3, valve 4, valve 5, final dusting pipeline 6, final dusting pipeline 7 behind the utility model converter stove.
Valve 4 is installed on the airduct 2.
Valve 5 is installed on the airduct 3.
Before the converter tapping, valve 4, valve 5 are opened automatically, and the flue dust that produces during converter tapping is inhaled in the dust hood 1, and in airduct 2, airduct 3 enter final dusting pipeline 6, final dusting pipeline 7 respectively.
Technological process of the present utility model is such:
A) at first import valve 4, valve 5 switch signals into converter PLC;
B) on HMI or operator's console, show valve 4, valve 5 working ordeies, and can be on HMI or operator's console the manual switch of operated valve 4, valve 5.
C) before the converter tapping, operator select valve 4, valve 5 " to open " on HMI or operator's console, and valve 4, valve 5 are opened automatically.
D) after affirmation final dusting blower fan is in running status, tapping.
E) after tapping finished, operator selected valve 4, valve 5 " pass " on HMI or operator's console, and valve 4, valve 5 are closed automatically.
