By accompanying drawing Fig. 1, shown in Figure 2, a kind of wet type combination smoke dust-removing desulfurating apparatus, comprise two or single inner core 7 are set in the urceolus 3, on the sidewall on urceolus 3 tops gas approach 6 is set, absorption liquid ring pipe 5 is laid at the top of urceolus 3, and absorption liquid ring pipe 5 connects spraying layer I 16, spraying layer I 16 be arranged on urceolus 3 top boards below, the bottom of urceolus 3 inner chambers is a circulating slot 14; The bottom of inner core 7 is provided with air port 1, the inner chamber of inner core 71 is spray uptake zone 8 to central region from the air port, and spray is provided with spraying layer II 9 above the uptake zone 8, and demist layer 10 is set above the spraying layer II 9, the flue gas mouth is set above the demist layer 10, and the flue gas mouth of two or single inner cores 7 connects exhanst gas outlet 11.
The overflow mouth of pipe 12 is set on the sidewall of urceolus 3 bottoms, replenishes the liquid mouth of pipe 13 and the circulation fluid mouth of pipe 15, the overflow mouth of pipe 12, the additional liquid mouth of pipe 13 and the circulation fluid mouth of pipe 15 communication loop grooves 14.The outer wall of the inwall of urceolus 3 and inner core 7 is formed flue gas spin chamber 2.Spraying layer II 9 is set to the 1-3 layer, and every layer is provided with a plurality of shower nozzles 4.Demist layer 10 is set to the 1-2 level, and the demister of demist layer 10 is deflector type or screen type structure.Spraying layer I 16 is provided with a plurality of shower nozzles 4.Each parts can adopt multiple material manufacturing.
Operation principle of the present utility model is:
Coal-fired furnace kiln burning back produces flue gas, and the harmful components in the flue gas mainly are sulfur dioxide and flue dust grain etc.The purification of flue gas of the present utility model is through eddy flow cooling and preliminary Off sulphur and the dedusting of big portion, impacts dedusting and absorbs sulfur dioxide, and foam absorbs sulfur dioxide, and spray absorbs four processes of sulfur dioxide.
The gas cleaning flow process: flue gas is sent into gas approach 6 through blower fan, and flue gas enters urceolus 3 Inner, and by cooling of spraying layer I 16 spray and preliminary Off sulphur, most of flue dust is thrown by eddy flow centrifugal force and is absorbed liquid to urceolus Inner wall and captures and remove at 2 Inner of flue gas spin chamber; After the flue gas cooling, with the air port 1 of certain wind speed by Inner tube 7, flue gas is wiped face and mistake by Inner tube air port and bottom liquid, forms and impacts, and flue dust is turned to the power of falling to throw suddenly to be absorbed the liquid capture to circulating slot by flue gas and removes; Flue gas is wiped face and mistake by Inner tube air port and bottom liquid, forms to take away partially liq when impacting, and forms the froth bed of certain altitude in 8 bottoms, spray uptake zone of Inner tube 7; Flue gas rises to spray uptake zone 8 by behind the froth bed, and absorption liquid contacts with the rising flue gas from 9 ejections of spraying layer II simultaneously.Above-mentioned each process all can make flue gas and absorption liquid form the turbulent airflow that the gas, liquid, solid three-phase system reconfigures, and makes flue gas and absorption liquid fully contact and the mass transfer absorption.Through above-mentioned four processes, sulfur dioxide in flue gas and flue dust grain obtain sufficient Off and remove, and flue gas becomes the purification flue gas.Purify flue gas and leave spray district 8, through the demister of demist layer 10, the Shui Wu Droplets that carries secretly in the flue gas is removed, and flue gas is after demist, and the weight percent content of foam is less than 7%.The flue gas that purifies enters flue through exhanst gas outlet 11, enters atmosphere to smokestack.Demister can adopt deflector type or screen type structure, selects stainless steel or Zou propylene material for use.
The absorption liquid workflow: absorption liquid is sent into two place's spraying layers through circulating pump, and a place is 1 layer of spraying layer I 16 on urceolus 3 tops, and another place is the spraying layer II 9 in the Inner tube 7.The absorption liquid of shower nozzle 4 ejection of spraying layer I 16 forms following current with flue gas and contact, flue gas be cooled with tentatively Off sulphur and most of dedusting after, absorption liquid enters in the circulating slot 14 of tower bottom; Spraying layer II 9 is designed to the 1-3 layer, every layer several shower nozzles 4 are installed, it is 0.3 μ m～0.5 μ m particle-liquid that shower nozzle 4 sprays out diameter, flue gas is covered at many levels and mixes, the quantity of the number of plies of spraying layer II 9 and shower nozzle 4 has determined spray flux, and the spray coverage rate has determined the removal effect of sulfur dioxide in flue gas.The absorption liquid of spraying layer II 9 ejections forms counter current contacting in spray uptake zone 8 with flue gas, oxysulfide in the flue gas is contacted fully with absorption liquid and is spread, harmful components are fully absorbed by spray liquid in the flue gas, total absorptivity is reached more than 95%, and absorption liquid captures the grit in the flue gas simultaneously.Absorption liquid enters in the tower bottom circulating slot 14; Absorption liquid is delivered to spraying layer I 16 and spraying layer II 9 through the circulating slot 14 circulation fluid mouths of pipe 15 by circulating pump, and absorption liquid is discharged circulating slot 14 by the overflow mouth of pipe 12; Replenish liquid and enter circulating slot 14 by replenishing the liquid mouth of pipe 13.
