Abstract
The utility model relates to a water -mist deduster, including the barrel, characterized by: from upward down being equipped with washing layer, dehydration layer in proper order, firstly spraying that layer, first raschig ring packing layer, second spray layer, second raschig ring packing layer in the barrel. Water -mist deduster compares with the existing product, and inner structure is tighter reasonable, and later maintenance is convenient, and cost of maintenance is low, double -deck spray set has improved the cooling speed of flue gas greatly, and the efficiency of dust particle production coalescence is higher, the raschig ring packs and the combination on the layer of dewatering is used, has prevented the come -up of dust -laden water smoke effectively, has improved the mass transfer separation efficiency of tower simultaneously greatly, the washing layer has prevented effectively that dehydration layer and raschig ring filler from being blockked up by sludge, and the dust collection efficiency obtains fine assurance.
Description
Technical field
This utility model is related to a kind of cleaner unit, especially a kind of mist dust remover.
Background technology
Process in dust pelletizing system in aod stove slag produced from steel-smelting, the flue gas of collection first passes through cyclone dust extractor and collects greater particle size
Dust, then through mist dust remover collect compared with small particle dust, make the flue gas mass after purification meet the row of national regulation
Put standard, realize the dust of different-grain diameter is collected simultaneously, the classification beneficial to slag recycles.
Mist dust remover is a kind of wet scrubber.Spray washing formula cleaner unit is one kind of wet scrubber.Water smoke removes
Dirt device is to be formed according to the operation principle improvement of spray washing formula cleaner unit.Scrubbing tower is that a kind of utilization washes principle, to gas
Carry out being humidified, wash, the equipment of dedusting, cooling and chemical reaction, be mainly used in steelwork converter flue gas washing in steel industry
Dedusting and cooling.Middle void tower is one kind of scrubbing tower, is typical gas wet processing apparatus；It is no any component in scrubbing tower
Setting, using the direct shower water of nozzle, aqueous slkali or other solution, reaches humidification, washing, dedusting, cooling or chemical reaction
Purpose.Have that structure is simple, application is convenient, low cost the features such as.Middle void tower is mostly columnar structured, reverse-flow workflow
Journey, is made using steel plate, makes of rustless steel during seriously corroded.Calculate by dust collecting process, design and sprinkling equipment is installed, typically
Using bowl-type nozzle, the water droplet of atomization is up to thinner degree.Existing product only has the purpose of humidification dedusting, and the flue gas discharged
Containing steam, overall work environment is had an impact.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mist dust remover, and dedusting is imitated
Rate is high, and internal structure is more reasonable, convenient later maintenance, and maintenance cost is low.
The technical scheme providing according to this utility model, described mist dust remover, including cylinder, it is characterized in that: described cylinder
Internal be sequentially provided with from top to bottom scrubber layer, dehydration layer, the first spraying layer, the first Raschig ring filler layer, the second spraying layer, second
Raschig ring filler layer.
It is provided with smoke inlet, cylinder top is provided with exhanst gas outlet below described cylinder.
Described cylinder body bottom is tapered and is provided with blowoff valve.
It is respectively equipped with some shower nozzles on described first spraying layer, the second spraying layer and scrubber layer.
Mist dust remover described in the utility model is compared with existing product, and internal structure is more reasonable, later maintenance
Convenient, maintenance cost is low；Double spray device substantially increases the cooling rate of flue gas, and powder dust particle produces the efficiency of coalescence more
High；Raschig ring filler is applied in combination with dehydration layer, effectively prevents the floating of dust-laden water smoke, substantially increases tower simultaneously
Mass transfer separation efficiency；Scrubber layer effectively prevent dehydration layer and Raschig ring filler is blocked by dirt mud, and efficiency of dust collection obtains very well
Guarantee.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: described mist dust remover includes the first spraying layer 1, the first Raschig ring filler layer 2, dehydration layer 3, washes
Wash layer 4, cylinder 5, the second spraying layer 6, the second Raschig ring filler layer 7, smoke inlet 8, exhanst gas outlet 9, blowoff valve 10 etc..
This utility model includes cylinder 5, is provided with smoke inlet 8 below cylinder 5, and cylinder 5 top is provided with exhanst gas outlet 9, cylinder
Body 5 bottom is tapered and is provided with blowoff valve 10；It is sequentially provided with scrubber layer 4, dehydration layer 3, first spray from top to bottom in described cylinder 5
Drench layer 1, the first Raschig ring filler layer 2, the second spraying layer 6, the second Raschig ring filler layer 7；First spraying layer 1, the second spraying layer 6
With some shower nozzles are respectively equipped with scrubber layer 4.
Operation principle of the present utility model and work process: as shown in figure 1, flue gas enters in cylinder 5, in the first spraying layer
1 and second spraying layer 6 continuous spray under, powder dust particle produces coalescence, completes flue gas humidification, washing, dedusting and cooling, sewage
Go downstream and enter Sedimentation tank；Part dust-laden steam is through the first Raschig ring filler layer 2, the second Raschig ring filler layer 7 and dehydration
The stop of layer 3, wherein, Raschig ring filler percent opening is high, and space is big, and flux is big, resistance little so that the gas in cylinder and liquid
Can pass freely through, the gas in the first Raschig ring filler layer 2 and the second Raschig ring filler layer 7 and liquid distribution situation are more good
Good, especially filler ring inner surface is easily moistened by liquid, regardless of its orientation, is showered into the liquid on filler, some edges
Outer wall flows, and have flows along inwall.So, liquid dispersion degree increases, and the utilization rate of filler inner surface improves, and therefore not only has
There are larger handling capacity and relatively low pressure drop, and mass transfer separation efficiency is also high；Dehydration layer 3 can prevent dust-laden steam to be discharged to greatly
In gas；After running one section of cycle, scrubber layer 4 periodically turns on, and rinses dehydration layer 3 and the first Raschig ring filler layer 2, the second Raschig ring
Packing layer 7, scrubber layer 4 can prevent dirt mud from blocking；Last sewage all flows in Sedimentation tank, is easy to recycle, purification gas are arranged
Go out.
