Abstract
The utility model relates to a filter device for dust removal in high temperature flue gas of electric furnace steelmaking. The sintering felt filter drum is a flat type or truncated conical filter drum. The truncated conical filter drum is in a conical shape with a large top and a small bottom, and a framework is supported inside the filter drum. The filter drum is made of stainless steel fiber sintering felt or iron-chromium-aluminum fiber sintering felt. The sintering felt filter drum adopts the leaching means to carry out filtering, and the filtering purpose is achieved after flue gas flows into the drum from outside to be filtered. The high-temperature exhaust gas of electric furnace steelmaking filtered by the sintering felt filter drum has clean high-temperature gas, and heat of the high-temperature gas can be recycled.
Description
Technical field
The utility model relates to a kind of filter of high-temperature gas, specifically the filter used of electric furnace steel making high temperature fume dust removal.
Background technology
The flue gas that electric furnace steel making is discharged, the temperature of its outlet is 650 ℃～1000 ℃.The traditional treatment method of electric furnace steel making flue gas is, cools to about 400～600 ℃ by pipeline, forces blowing with the cooled flue gas temperature again, carries out bag-type dust after flue-gas temperature is reduced to 220 ℃.This method, dust removing effects is poor, and the facility of dedusting is complicated and occupy the space, and cloth bag damages in high temperature environment easily, and importantly the waste heat of flue gas is not used.
The utility model content
The purpose of this utility model is, overcomes the deficiency of traditional dedusting technology, the novel filter that provides a kind of efficiency of dust collection height, waste heat to be fully utilized---metallic fiber sintered felt filter cylinder.
The technical scheme that the utility model adopted is that the metal fiber felt reel is welded into platypelloid type filter cylinder or truncated cone-shaped filter cylinder.Its filter cylinder material is stainless steel fibre sintering felt or iron-chromium-aluminum sintering felt.Cartridge interior has skeleton to support.
When installing and using, if cylinder dedusting filter bag, then one is welded on the orifice plate, and the size in hole is identical with above the cylinder mouthful, and the other end is that weldering is dead; If the platypelloid type filter cylinder, then a weldering is dead, and flat bag has an end of flange to hang on the orifice plate, adds a detachable pressing plate above again, is convenient to change filter bag.
The fiber sintering felt serving filter cylinder of the utility model is the filter type of suction filtration, promptly when flue gas from outside when flowing in the tube by filter cylinder, reached the purpose of filtration.For preventing that filter bag from being taken out flatly, adopt the method for blowback from inside to outside during the filter cylinder deashing.
Described two kinds of sintering felt materials have serviceability temperature scope separately: stainless steel fibre sintering felt is in the electric furnace flue gas dedusting, and the temperature of suitable use is 500～550 ℃, and siderochrome aluminum sinter felt suitable serviceability temperature be 560～1000 ℃; The filtering accuracy of fibrofelt is controlled at 15～30 μ m.The dust size that the electric furnace fire door is discharged is quite little, particle diameter less than the dust of 10 μ m more than 80%.When entering the filter entrance concentration at 15～30g/m
3The time, the filtering accuracy of selecting metallic fiber sintered felt for use be 15～30 μ m can qualified discharge (GB is＜30mg/m
3).
If adopt metal fiber felt directly to carry out blast furnace flue gas tail gas clean-up, smoke dust discharge concentration＜20mg/m
3(GB is＜30mg/m
3).Waste heat can fully utilize, and according to measuring and calculating, smelts steel waste heat recovery per ton and can save 37.9 ° of electricity (amounting to 12.7 kilograms of mark coals).
Metal fiber felt is to be welded by fiber high temperature metallurgy, without any binding agent, has good gas permeability, and under equal filtering accuracy, its air permeability is 2 times of other filtrates; The elevated temperature strength height, the temperature of high use can reach 1000 ℃.Dust is peeled off the rate height.Be particularly useful for 500～1000 ℃ gas cleaning at high temperature; And have long service life, advantage such as it is little to take up room, easy and simple to handle, through the electric furnace steel making high-temperature tail gas that the utility model filters, the heat energy of the high-temperature gas of cleaning can be recycled.

The specific embodiment
Below in conjunction with two embodiment of the present utility model of accompanying drawing narration.
Embodiment 1. truncated cone-shaped filter cylinders.
As shown in Figure 1: will fan ring metallic fiber sintered felt 2, volume is welded into tubbiness, corrosion resistant plate ring 1 and metal fiber felt welding, and plate ring 3, corrosion resistant plate ring 1 elder generation and metal fiber felt welding weld with the filter cylinder bottom again.The tube on the lower end the size difference---purpose is to help the Compressed Gas reverse gas cleaning, the filter material favorable regeneration effect.The garden diameter of tube upper end is φ 145～160mm.The garden diameter of tube lower end is φ 125～140mm, filter cylinder height 1200～1600mm.
Embodiment 2. flat filter cylinders.
As shown in Figure 2: metal fiber felt 5 volumes are welded into flat tubbiness, connect the siderochrome aluminium sheet ring flat-plate ring 6 and metal fiber felt 5 welding of bottom, weld with flange then.Siderochrome aluminium sheet ring 4 and metal fiber felt 5 welding weld with the filter cylinder bottom then.Its mouthful is oval size up and down, its objective is the volume that reduces cleaner, and oval length is 480～520mm, filter cylinder thickness 50～55mm, height 1000～1600mm, half garden R20～25mm.
