Technical field:
The utility model relates to metallurgical environmental protection equipment technical field, particularly relates to the atomization spray dust removal device of a kind of blast furnace discharge yard iron mouth and main iron hook overlying regions.
Background technology:
In the prior art, dedusting in blast furnace casting field is the technical barrier that iron work is difficult to effectively solve always.In blast furnace ironmaking is produced, there is the excessive phenomenon of volume of smoke in casting house when tapping a blast furnace, especially when tapping outlet and stifled iron notch, iron mouth place produces volume of smoke, and molten iron per ton produces 2.5kg flue dust, and operational zone dust concentration can up to 2 ~ 3g/Nm
3, post dust content is high, and working condition and operating environment are extremely severe, bring great threat to the health of operator and environmental pollution.Casting house airborne dust point is mainly distributed in the places such as iron mouth, skimmer, iron runner, slag runner, iron ladle, correspondingly take the dust suppressions such as iron mouth dust excluding hood, skimmer dedusting, slag iron runner cover plate, iron ladle dust excluding hood, but the secondary pollution of iron mouth and main iron hook regional dust is still very serious.To this secondary pollution, field personnel takes to control flue dust diffusion with hydraulic giant to the method that iron mouth upper area is fetched water usually, and some iron work does not even deal with flue dust, lets alone big area diffusion.There is its own shortcomings and deficiency in this dedusting present situation: 1. mechanization degree is low; 2. workman's labor operation intensity is large; 3. dust removing effects is undesirable, and post dust concentration is much larger than 10mg/Nm
3; 4. the cleaning apparatus of a set of effective modernization, automatization is lacked; 5. work under bad environment, causes serious harm to operator's health of human body.
Utility model content:
The purpose of this utility model is the shortcoming and defect overcoming prior art existence, there is provided one spatially can cover casting house iron mouth, main iron hook region, and effectively can catch iron-collecting mouth and main iron hook regional dust and improve casting house dedusting mechanize and automatization level, improve the casting house atomization spray dust removal device of casting house stokehold operating environment.
Technical solution of the present utility model is to provide a kind of casting house atomization spray dust removal device, comprises high-pressure feed water bag, in-line pump that blast furnace tuyere platform is installed; It is characterized in that: also comprise electric butterfly valve, vacuum breaker, manual ball valve, pulse valve, PLC system, dust detector, can produce wide-angle full jet spraying the full jet atomization shower nozzle of wide-angle; High-pressure feed water contracts out water pipe and is connected with two in-line pumps, two in-line pump parallel connections, in-line pump inlet channel place is provided with electric butterfly valve and vacuum breaker, outlet conduit place is provided with manual ball valve, two in-line pump rising pipes are communicated with a main pipeline, and be communicated with the full jet atomization shower nozzle of iron mouth and the wide-angle of main iron hook overlying regions, the vibration means for main pipe for supplying water road of atomizer is provided with pulse valve, and pulse valve is connected with dust detector by PLC system; Dust detector is arranged on above iron port area; Two in-line pump the using and the reserved; Dedusting position is provided with dust concentration to exceed standard alarm lamp; The dust concentration alarm lamp that exceeds standard is connected by data line with PLC system; Atomizer has multiple, and its quantity is according to atomizing spray area being made all to cover iron mouth and whole main iron hook region and aerosol curtain stops flue dust to configure to the demand of tuyere platform and casting house external diffusion together with being formed with main iron hook region vertical direction at iron mouth; Mounting arrangements atomizer on roof steel structure above iron notch and main iron hook; The inlet channel that atomizer is communicated with is communicated with the high-pressure feed water bag that blast furnace tuyere platform is installed.Its principle of work is: supplied water by tuyere platform high-pressure feed water bag, two in-line pump the using and the reserved, and control spray water supply by opening and closing electric butterfly valve, the timed interval of atomizing spray is controlled by pulse valve and regulates.When tapping outlet and stifled iron notch, iron port area can produce volume of smoke, and the dust detector be installed on above iron port area detects that dust concentration is greater than 10mg/Nm
3alarm pilot lamp lights, and outputs signal to PLC system simultaneously, PLC system according to dust concentration size adjustment pulse valve opening/closing time interval, to control spray water flow.After spraying and dedusting for some time, when dust detector detects that dust concentration is less than 10mg/Nm
3time, alarm lamp recovers normal, and output signal to PLC system simultaneously and close pulse valve, now atomizer stops spray, and dedusting terminates.
The beneficial effects of the utility model are: dedusting area coverage is large, occupation area of equipment is little, install simple, automatization and mechanization degree high, can automatically regulate spray time interval according to the change of dust concentration in casting house environment, reduce dedusting air quantity, reduce water consumption and power consumption, and the dust granules in energy Quick Catch flue gas, the dust filled the air in a large number in effective settle air, makes iron mouth and main iron hook regional dust concentration by starting point concentration 180mg/Nm
3be decreased to 10mg/Nm
3below, greatly improve casting house staff labor operation environment and atmospheric environment, ensure that staff's is healthy.
