The specific embodiment
Of the present utility model along dash the atomizing desulfurizing dust-collector against gas, shown in Fig. 1-4, comprise and connect boiler flue 1 and sulphur removal pipeline 2, sulphur removal pipeline 2 has first pipeline 21 and second pipeline 22 that is the vertical direction setting respectively, the upper end of first pipeline 21 is undertaken in the outlet that connects boiler flue 1, the upper end of second pipeline 22 is the Purge gas outlet, and the lower end of first pipeline 21 and second pipeline 22 is a base 23.
Following current reaction zone 24 is provided with following current high-pressure atomizer 241,242, and following current high-pressure atomizer 241,242 is divided into two differing heights places of following current reaction zone 24.
Impact type reaction zone 25 is provided with down trapezoidal gas towards liquid chamber, this falls the back impact swash plate 252 that trapezoidal gas has the preceding impact swash plate 251 that is undertaken in following current reaction zone 24 rear ends and is undertaken in mixing and contacting reaction district 26 front ends towards liquid chamber, and the top of swash plate 252 is impacted in the back and the bottom of first pipeline 21 flushes.The bottom of impact type reaction zone 25 is provided with overfall 253, and the water of being gone out by flue gas from then on overfall 253 flows out.The trapezoidal gas that falls is provided with slag-drip opening 254 towards the bottom of liquid chamber.
Mixing and contacting reaction district 26 be arranged at second pipeline 22 the bottom, be undertaken in the rear (top) of impact type reaction zone 25, mixing and contacting reaction district 26 is provided with one group of mixing contact plate 261 that tilts.
The top in mixing and contacting reaction district 26 is a counter-flow reaction zone 27, and counter-flow reaction zone 27 is provided with adverse current high-pressure atomizer 271 one.
Operation principle of the present utility model is as follows:
Doctor solution is introduced desulphurization plant by water circulating pump, delivers to following current high-pressure atomizer 241,242, and following current high-pressure atomizer 241,242 produces a large amount of atomized drops, for good reaction condition is created in gas-liquid contact, reaction.Mixed flue gas enters following current reaction zone 24 with certain flow velocity by the upper end of first pipeline 21, produces a large amount of atomized drops by following current high-pressure atomizer 241,242 and carries out elementary desulfurization.
Flue gas after the 24 elementary desulfurization of following current reaction zone rushes at down trapezoidal gas towards liquid chamber, rushes at back impact swash plate 252 until impacting to preceding impact swash plate 251, being folded to subsequently, impacts swash plate 252 along the back at last and goes out down trapezoidal gas towards liquid chamber.Flue gas all pulls the plug during towards liquid chamber through falling trapezoidal gas, through falling after trapezoidal gas comes out towards liquid chamber " washing " SO in the flue gas
2Content reduces greatly, and this stage is full permeable reactive zone.When exhaust gas volumn is big, the flue gas impulsive force is big, the trapezoidal gas that falls is rushed out more towards the water in the liquid chamber, when exhaust gas volumn hour, the flue gas impulsive force is little, and the trapezoidal gas that falls is rushed out less towards the water in the liquid chamber, like this, this falls the liquid level of trapezoidal gas in the liquid chamber and can regulate water level automatically according to the flue gas fluctuation, have advantages such as power consumption is few, SR is little, convenient operation and management.The water of being gone out by flue gas flows out from overfall 253, and the trapezoidal gas that falls is discharged from slag-drip opening 254 towards the sediment of liquid chamber bottom.
Enter mixing and contacting reaction district 26 by falling a large amount of sprays and the water smoke that trapezoidal gas takes out of towards liquid chamber, make jointly with doctor solution that adverse current high-pressure atomizer 261 sprays and to mix contact plate 261 upper and lower surfaces and all produce water membrane, increase gas-liquid contact-making surface also extends contact time, and makes the SO that does not purify
2Further removed at this.
Flue gas continues up, enters counter-flow reaction zone 27, compares with following current reaction zone 24, counter-flow reaction zone 27 more apparent advantages, because ascending air and the doctor solution that sprays belong to reverse movement, this more helps making between the gas-liquid, strengthen between the gas vapour and contact and mix, and allows rare light SO in the flue gas
2Effectively removed.
Flue gas after the processing enters dehydration district 28 and dewaters, and the dewater unit in dehydration district 28 adopts collapsible dewatering plate 281, and small droplet is through repeatedly collision, aggegation and be separated.
Dehydration back flue gas is introduced chimney row to atmosphere by brick air-returen flue (or steel flue gas duct) through air-introduced machine.Drop under doctor solution behind the dust-removal and desulfurizing and 281 collections of collapsible dewatering plate comes together in down trapezoidal gas towards the liquid chamber bottom, is discharged by slag-drip opening 254.
