Along with industrialized extensive development, the exhaust gas volumn that Industrial Stoves and station boiler discharge increases year by year, the subparticle substrate concentration in air is caused significantly to raise, these fine particles are rich in poisonous and harmful substance in a large number, atmospheric residence time is long, fed distance is far away, thus causes high risks to health and atmosphere quality.
At present, most industrial furnace has installed cleaner on flue, and relatively more conventional has sack cleaner and electrostatic precipitator.Sack cleaner is moderate, and floor space is wide, and power consumption is large, and filter bag often needs to change, and later maintenance costly.Electrostatic precipitator needs to charged system level design with the needs adapting to different-grain diameter grit, and often cause complex structure, cost raises.Also have some Industrial Stoves on flue, installed water dust scrubber, but spray forms moisture film water consumption greatly, be applicable to the place near sufficient water source, power consumption is high, and water pollutions is serious, and later stage water treatment is costly.Shanghai Longking Environmental Protection Co., Ltd. has issued a kind of device of wet process of FGD cooperation-removal subparticle, adopts steam phase transforming that fine particle condensation shock is grown up, finally adopts the removing of flue demister; North China Electric Power University discloses thermophoresis type cyclone separator for objects of subparticle, adopts thermophoresis principle and centrifugal rotation effect to remove fine particle.
In above device, to improve the removal efficiency of fine particle, the complexity of dust arrester structure certainly will be increased, improving processing and manufacturing cost.Therefore, be necessary that development is cheap, the device of the removal fine particle that removal efficiency is higher.
Utility model content
In order to overcome the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of wet method to remove the molecular sieve device of fine particle in flue dust, and the utility model structure is simple, remove that cost is low, removal efficiency is high.
For achieving the above object, the utility model adopts following technical scheme:
Wet method removes a molecular sieve device for fine particle in flue dust, comprises vapor removal room, hothouse and molecular sieve and removes room; The air inlet end of vapor removal room is provided with into fume pipe, top, vapor removal room is provided with into steam pipe, bottom, vapor removal room is provided with drain pipe, be connected with flue gas between the outlet side of vapor removal room and the air inlet end of hothouse to go out to manage, drying tube is connected with between the air inlet end that the outlet side of hothouse and molecular sieve remove room, the outlet side that molecular sieve removes room is connected with fresh-air duct, and molecular sieve removes in room and is provided with molecular sieve.
Further, the top of vapor removal room is provided with gas skirt, and the bottom of gas skirt is provided with porous air dividing plate, enters the top that steam pipe is connected to gas skirt.
Further, the bottom of vapor removal room is provided with hydrophobic room, and drain pipe is connected to the bottom of hydrophobic room.
Further, some spoilers distributed alternatively up and down are provided with in vapor removal chamber interior cavity.
Further, porous plate after porous plate and first before being provided with first in hothouse, and be provided with active carbon between porous plate after porous plate and first before first.
Further, porous plate after porous plate and second before molecular sieve removes and is provided with second in room, before molecular sieve is arranged on second between porous plate and the second rear porous plate.
Compared with prior art, the utility model has following useful technique effect:
In flue dust, contained grit particle diameter is different, and for the particulate being greater than 10 μm, the vapor removal room removing arranged by the utility model, is removed after now mainly adopting steam-condensation to make their uniform agglomeration, compares existing spray and atomization method compares water-saving; For the particulate being less than 10 μm, then molecular sieve can be adopted to remove the molecular sieve arranged in room and all remove, because molecular sieve pore passage only allows molecule to pass through, removal efficiency is high;
Further, top, vapor removal room of the present utility model is provided with gas skirt, and gas skirt bottom is provided with porous air dividing plate, and like this from entering steam that steam pipe comes in by after porous air dividing plate, distribution is relatively more even, can improve removal efficiency;
Further, in vapor removal room of the present utility model, some spoilers are installed, the time of staying of steam can be extended, steam fully and smoke contacts, can be improved steam-condensation and remove fine particle effect;
Further, the flue gas out from vapor removal room, first pass into moisture removal in hothouse, and porous plate after porous plate and first before being provided with first in hothouse, vapor removal room flue gas is out contacted with active carbon evenly, moisture removal efficiency comparison is high, equally, porous plate after porous plate and second before molecular sieve removes and is provided with second in room, so molecular sieve fully contacts with the flue gas of coming in, the removal efficiency of fine particle is higher, and first drying removes fine particle again, effect of follow-up molecular sieve can be given full play to, improve its service life.
