Abstract
The utility model relates to a sulfur and dust removal two-stage combination device, pertaining to the environmental protection technological field, which mainly settles the environmental pollution caused by smoke dust and sulfur dioxide of the smoke discharged by a boiler and a kiln. The utility model combines and utilizes the dry dust removal and wet sulfur removal skillfully, thus fulfilling the best effect of two-stage sulfur and dust removal.
Description
Technical field
The utility model relates to a kind of desulfurization and dedusting twin-stage composite set, belong to environmental technology field.Mainly solve flue dust and sulfur dioxide (SO2) emissions pollution on the environment in boiler, the kiln discharging flue gas, the utility model is used in combination dry dust removal with wet type desulfurizing is ingenious, thus the optimum efficiency of realization two-stage dust removal desulfurization.
Background technology
Present existing deduster generally only has dedusting function, does not have desulfurizing function; The device that has combines desulfurization and dedusting, but desulfuration efficiency is very low, and produces all very big, a large amount of dirt slurry intractable of amount and concentration of dirt slurry, diluted acid mud can produce very strong corrosive wear to devulcanizer, causes the service life of desulfation dust-extraction device very low.Because dirt slurry is dense, thus sweetening process produce in close liquid and also be difficult to reuse, increased operating cost, and air-introduced machine band water has reduced its service life again.
Summary of the invention
The purpose of this utility model exactly for the desulfurization that improves device, the efficient of dedusting, increases service life, realizes the reuse of desulfurization neutralizer, reduces operating cost.
Realize by following proposal by the purpose of this utility model: at first about 90% dust in the flue gas is removed by dry centrifugal collector, the less dust of residue is removed by the wet type desulfurizing device in the flue gas, therefore after the wet type desulfurizing device is finished dust-removal and desulfurizing, dust content is lower in the neutralizer, and is promptly reusable through the sedimentation basin post precipitation; This device is installed in air-introduced machine before the wet type desulfurizing device, is not with water so guarantee air-introduced machine when operation.
The utility model has following advantage after adopting technique scheme: the two-stage dust removal desulfuration efficiency is higher; The desulfurization neutralizer is reusable, reduces operating cost; The desulfurization neutralizer can utilize boiler blow-off waste water to replace, and realizes the treatment of wastes with processes of wastes against one another.Avoid the water running of air-introduced machine band, improve service life.
Description of drawings
Fig. 1 is according to the double-stage desulfurizing dedusting composite set schematic diagram that the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
This device is by dry collector 6, connects that flue 4, air-introduced machine 3, wet type desulfurizing device 13, collection slag bath 9, neutralizer sedimentation basin 14, neutralizer manage 20 down on pipe 15, the neutralizer, neutralizer elevator pump 19 is formed by combining.Dry collector 6 is connected outlet 5 and is formed by smoke inlet 7, flue dust sedimentator 11, dust collecting opening 8, flue gas; Wet type desulfurizing device 13 is made up of connection smoke inlet 2, neutralizer inlet 1, neutralizer spray cap 18, deposition tube 12, mud mouth 10, neutralizer outlet 16, exhanst gas outlet 17.The flue gas that boiler or kiln produce at first enters dry collector 6 by smoke inlet 7, after removing the wherein most dust granule of cigarette by the effect of flue dust sedimentator 11, dust is discharged to collection slag bath 9 after being collected by dust collecting opening 8, flue gas behind the primary dust removing connects outlet 5 by flue gas and discharges, be connected smoke inlet 2 through what connect that flue 4 and air-introduced machine 3 enter wet type desulfurizing device 13, neutralizer elevator pump 19 in the device sprays with powerful pressure neutralizer to spray cap 18, this moment just with from contacting by being connected the flue gas that smoke inlet 2 enters, trickle grit in the flue gas is adsorbed on the trickle globule, being condensed into larger particles separates from flue gas, heavy gathering in deposition tube 12, realize two-stage dust removal, grit is removed from mud mouth 10.In addition, neutralizer makes the SO in the flue gas in the spray process
2Fully contact with neutralizer, realize desulphurization reaction, the flue gas after the desulfurization is discharged from exhanst gas outlet 17.In close reacted neutralizer from neutralizer outlet 16, by neutralizer pipe 15 down, flow into neutralizer sedimentation basin 14, after precipitate and separate, the effect via pipe 20 and neutralizer elevator pump 19 on the neutralizer recycles.
