Electric flap automatically controls to realize.
It is briefly described as follows the operation logic of above preferred embodiment:
Firstly, 1 flue gas of ferrosilicon furnace absorbs waste heat by high-temperature residual heat utilization device 2, flue-gas temperature is reduced；Export cigarette
The direct high-temperature electric of gas is packed to be set 3 and is dusted processing, need to be equipped with cyclone pre-dusting compared with mixer selector valve with traditional scheme, this programme
3 are set using high-temperature electric is packed, the setting of no setting is required cyclone pre-dusting and mixer selector valve reduces the process of fume treatment, and can save
About occupation area of equipment.
It, can will be under most large dust particle collects secondly, when flue gas flows through that high-temperature electric is packed to set 3 electric area 31
, fine solid particle partial size under the coagulation in electric area 31 and effect increases, and dust is by charged and then process metal filter bag
Loose cake layer will be formed in filter bag surface when area 32, so that making the resistance of cleaner greatly reduces；At the same time, it passes through
It crosses the packed 3 electric area 31 of setting of high-temperature electric to collect most large dust particle, the dust content in bag area 32 will be promoted big
Width reduces, and soot blower period increases substantially, pressure needed for deashing decreases, the air capacity of consumption needed for deashing is reduced,
The packed service life for setting 3 bags of areas 32 of high-temperature electric can be extended；Flue gas after dedusting enters back into low-temperature residual heat utilization device 4
Low temperature exhaust heat in flue gas is recycled, the treating capacity of blower 5 can be substantially reduced, reduces the energy consumption of blower 5.With routine
Dedusting corollary equipment is compared, and high-temperature electric is packed to set 3, and whole system is relatively easy, operating cost is low, has preferable economic performance
It is good.
Next, this system selects low-temperature denitration device 6, this equipment component is placed on 5 downstream of blower by preferably ozone denitration
Side the problems such as no abrasion and blocking, guarantees nitrogen oxides ultralow row steady in a long-term compared with the denitration technologies such as traditional SCR
It puts.
Finally, this technology route mating flue gas reheat cooling device 7 and flue gas reheat heat riser 9, reach reduction cigarette
Water capacity in gas and the white effect that disappears, reducing the water capacity in flue gas is mainly to pass through the flue gas temperature for reducing desulfurization entrance side
Degree reduces the water consume of desulphurization system, and then reduces the water capacity in flue gas, disappears white mainly by the cooling of flue gas reheat system
Heat in 7 Absorption Desulfurization entrance side original flue gases of section, the heat that will be absorbed from former fume side by thermal medium (most of to use water)
Amount, which is sent to flue gas reheat heat riser 9, discharges heat into desulfurization outlet side neat stress, so that it is white to achieve the effect that disappear.
It illustrates, the functions such as ferrosilicon furnace is provided in this programme and constitute not this Applicant's Abstract graph central inventive point place,
Those skilled in the art can be selected based on system functional requirement, and therefore, this article will not repeat them here.
The above is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
It says, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should be regarded as
Protection scope of the present invention.
