Technical field
The present invention relates to a kind of air cleaning unit, specially cement exhaust-gas treatment integration unit.
Background technology
The fume treatment auxiliary being commonly used at present on cement industry has deduster, desulfurizing tower and the cigarette being independently arranged Chimney, deduster of the prior art typically adopts dry type and half dry type, and its housing typically adopts metal, arranges pottery in housing With PC plastic plate, desulfurizing tower of the prior art arranges spray equipment and filler typically just in housing, and filler typically adopts It is excessively simple, in flue dust and flue dust all to there is structure in PC plastic plate, granite and marble, these dedusters and desulfurizing tower The processing procedure of sulphur is excessively simple, thus treatment effect is undesirable, and these equipment are typically separately provided, construction land area Greatly, construction cost is high.
Content of the invention
For above-mentioned technical problem, the present invention provides a kind of cement exhaust-gas treatment integration unit, by dedusting, desulphurization and denitration Include same system to be processed, reducing energy consumption and investment.Specifically technical scheme is：
Cement exhaust-gas treatment integration unit, including treatment box, there is inlet channel described treatment box side, and opposite side is Gas passage；The bottom for the treatment of box is aeration tank；
Described inlet channel is connected with aeration tank respectively with the bottom of outlet passageway, above described aeration tank, also Spray equipment, described spray equipment is also located between inlet channel and the bottom of outlet passageway；
Corrugated plating is arranged at described spray equipment bottom；Described corrugated plating upward raised for crest, towards in aeration tank Projection be trough；Multiple shower nozzles are provided with described crest；
Aerator is also included in described aeration tank.
Air inlet is arranged at described inlet channel top, is combined oxidation oxidation unit below air inlet, and combined oxidation aoxidizes There is device for atomizing liquid below device；Below device for atomizing liquid, side spray head is distributed with the side wall of inlet channel；
Gas outlet is arranged at described outlet passageway top, is provided with demister below gas outlet, installs below demister There is water-locator, rotary gas-liquid silk screen is installed below water-locator.
Waste gas enters inlet channel from air inlet, carries out nitride and sulfide are carried out in combined oxidation oxidation unit Oxidation, changes into the material easily being absorbed by akaline liquid, and subsequently into aeration tank, after alkaline matter absorption, product and dust are by water Wash absorption, finally dehydration discharge.
The cement exhaust-gas treatment integration unit that the present invention provides, dedusting, desulphurization and denitration function are integrated into an equipment On, floor space is little, equipment investment is low, operation is easy.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The specific embodiment of the present invention is described with reference to the drawings, as shown in figure 1, cement exhaust-gas treatment integration unit, including Treatment box, there is inlet channel 1 described treatment box side, and opposite side is outlet passageway 2；The bottom for the treatment of box is aeration tank；
Described inlet channel 1 is connected with aeration tank respectively with the bottom of outlet passageway 2, above described aeration tank, also There is spray equipment 3, described spray equipment 3 is also located between inlet channel 1 and the bottom of outlet passageway 2；
Corrugated plating 31 is arranged at described spray equipment 3 bottom；Described corrugated plating 31 upward raised for crest, towards aeration Projection in pond is trough；Multiple shower nozzles 32 are provided with described crest；
Aerator 4 is also included in described aeration tank.
Air inlet 11 is arranged at described inlet channel 1 top, and air inlet 11 lower section is combined oxidation oxidation unit 2, composite oxygen Change and have device for atomizing liquid 13 below oxidation unit 2；Below device for atomizing liquid 13, it is distributed with the side wall of inlet channel 1 Side spray 14；
Gas outlet 21 is arranged at described outlet passageway 2 top, is provided with demister 22, demister 22 below gas outlet 21 Lower section is provided with water-locator 23, is provided with rotary gas-liquid silk screen 24 below water-locator 23.
The course of work is：Waste gas is incorporated into air inlet 11 through air-introduced machine and enters inlet channel 1, is introduced into combined oxidation oxygen Gasifying device 2, is placed with composite oxidant in combined oxidation oxidation unit 2, NO is oxidized to NO by composite oxidant2, SO2It is oxidized to SO3.There are gas outlet, gas outlet and combined oxidation oxidation unit 2 lower end device for atomizing liquid 13 in combined oxidation oxidation unit 2 side Connection, device for atomizing liquid 13 is atomized, and atomized liquid is ammoniacal liquor, by NO2Change into ammonium nitrate, SO2Change into sulphur ammonia.
Waste gas continues on inlet channel 1 and moves downward, and for improving efficiency, on the upside of inlet channel 1 side wall, shower nozzle 14 is to useless Gas carries out spray-absorption liquid；Then waste gas enters the aeration tank of bottom, has absorbing liquid in aeration tank；Liquid level in aeration tank and spray Shower device 3 bottom has and forms corrugated air duct between corrugated plating 31, goes out in trough, waste gas is contacted with the absorbing liquid water surface, Simultaneously at crest, there is shower nozzle 32 to carry out spray-absorption liquid, mainly remove dust in removing exhaust gas.Aeration dress is also included in aeration tank Put 4 so that the absorbing liquid water surface produces fluctuation, increase and exhaust gas contact face.
Then waste gas enters outlet passageway 2, and water-locator 23 sprays to rotary gas-liquid silk screen 24, in rotary gas-liquid Moisture film is formed on silk screen 24.Rotary gas-liquid silk screen 24 is arranged to rotary, can rotate rotary gas-liquid silk screen 24, if silk Net use time is long, and mesh is become silted up by dust and liquid mixture and ties, and can rotate and get rid of dust and liquid mixture.Final purification Gas through demister 22 remove steam, finally discharged from gas outlet 21.
