Description
Technical field
This utility model belongs to technical field of metallurgical equipment, belongs to technical field of dust removal equipment further, is specifically related to a kind of simple in construction, easy for installation, it is possible to effectively collect the converter tower ease fume collecting device of flue gas.
Background technology
In steelmaking operations, converter hot metal charging, blow, add steel scrap, tapping of fascinating, slag tap, repair stove, cutting fire door steel bonding time produce volume of smoke, be referred to as converter secondary flue gas.This part flue dust has the advantages that temperature is high, dust content is high, dust size is little, moment exhaust gas volumn is big, and its dissemination process is paroxysmal.The exhaust gas volumn distributed when converter secondary flue gas is with hot metal charging is maximum, next to that tap, add the processes such as steel scrap.During hot metal charging, filemot high-temperature flue gas diffuses up with the highest speed between hot-metal bottle and converter mouth, and initial temperature is about about 1200 DEG C, along with high-temperature flue gas diffuses up, volume inhales substantial amounts of workshop cold air, and when the column of smoke arrives crane girder, temperature is about 500～700 DEG C.
In order to trap flue dust, converter mouth is provided above enclosure, and enclosure (held court from behind a screen by petticoat pipe body and activity and constitute) is bilateral air draught type.During hot metal charging, flue-gas temperature is higher, and enclosure is affected by intense radiant heat for a long time, for preventing enclosure from burning out, deforming, is added lining refractories by intense radiant heat position inside enclosure.In auxiliary material and iron alloy material feeding, feeding system, the part dust such as batcher, belt transfer station, scale hooper also converges people's converter secondary flue gas dedusting blast main, for controlling the flue-gas temperature entering sack cleaner less than 120 DEG C, wild air-valve is set in cleaner unit porch, when flue-gas temperature is more than 120 DEG C, wild air-valve automatically turns on, and is mixed into extraneous air to reduce flue-gas temperature；When temperature reaches below 100 DEG C, wild air-valve is automatically switched off.Exhaust gas volumn according to hot metal charging, the generations such as stove of blowing, overhaul is different, and converter secondary flue gas dedusting is variable air rate dust pelletizing system, and blower fan uses frequency control motor, and rotation speed of fan is adjusted by the change according to smelting operating mode.
In present steelmaking operations, owing to the operating rate of equipment improves constantly, smelting load and continue to increase, iron ore quality declines in addition, causes converter smelting exhaust gas volumn to increase.Cause bigger splash owing to the silicone content of molten iron is higher, converter gas also can explosive increase therewith.Smelting the phase in oxygen blast, a large amount of flue gases escape at smoke evacuation overskirt mouth, more respectively at the sidepiece imprecision of converter enclosed hood and permeate in workshop in floor device activity aperture, top etc..Promote at nitrogen seal imprecision at oxygen rifle, also have flue gas to escape, rise to plant building top along oxygen rifle passage.When converter hot metal charging adds steel scrap, stokehold enclosure flue gas trapping rate is low, and heat smoke rushes at and escapes at femerell.The capture rate of flue gas declines, and in causing Factory Building, tobacco fills the air, and at Factory Building top, tobacco escapes, and working environment dust concentration is high, and worker works under hard conditions, the physical and mental health of serious harm workman；Escape tobacco and directly affects the air quality of surrounding, pollute environment；Metal in dust fails to reclaim, and affects the economic benefit of enterprise.
To this end, a kind of simple in construction of research and development, easy for installation, it is possible to the converter tower ease fume collecting device effectively collecting flue gas is the key solving this problem.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, easy for installation, it is possible to effectively collect the converter tower ease fume collecting device of flue gas.
The purpose of this utility model is achieved in that and includes that dust shield, dust removing tube, pillar, the outlet side of described dust shield arrange dust removing tube；The lower section of described dust removing tube arranges pillar；The air inlet of described dust shield is just to dust source；Described dust shield is horn-like.
Dust shield of the present utility model is horn-like, and the air inlet of dust shield is just to dust source, and the outlet side of dust shield arranges dust removing tube, and the lower section of dust removing tube arranges pillar.Dust shield is arranged near dust source, forms certain negative pressure with blower fan at dust shield inlet end, i.e. form certain wind speed at the place of flying upward of dust, dust, with wind flow, enters in dust shield, dust removing tube gets rid of, enter back into follow-up cleaner, cleaner collect.Pillar is set below dust removing tube, to facilitate, this device is moved at dust source.
This utility model can effectively trap flue gas, stops steel-making Factory Building tobacco and escapes, improve atmospheric environment, increases flue gas and escape collection rate；Reduce working environment dust concentration, improve worker's working condition, protect the physical and mental health of workman；Metal in efficient recovery dust, improves the economic benefit of enterprise.This utility model simple in construction, easy for installation, it is possible to effectively to collect converter tower ease cigarette.
