Embodiment
As Fig. 1, shown in 2, a kind of most preferred embodiment of tail gas clean-up cooling water washing device, has suction tude 1, steam outlet pipe 2, intake pipe 3, outlet pipe 4, water pump 5 and water washing box 7, water washing box 7 outsides are provided with and the inner water intake 31 that communicates, water washing box 7 bottom halves are provided with water outlet 41, outlet pipe 4 is communicated with water outlet 41, be respectively equipped with suction port 11 that is communicated with suction tude 1 and the air outlet 21 that is communicated with steam outlet pipe 2 near side edge water intake 31 both sides on the water washing box 7, water washing box 7 inner tops are provided with five showers 6 that are parallel to bottom half, shower 6 is provided with a plurality of hole for water sprayings 61, be provided with air guide dividing plate 9 between adjacent two showers 6, intake pipe 3 is made as two, and be communicated with shower 6 by two water intakes 31 respectively, wherein the water route in an intake pipe 3 and the suction tude 1 is communicated with, another intake pipe 3 is communicated with the water route of steam outlet pipe 2, be equipped with the water jacket of internal ventilation outer course water flowing in suction tude 1 and the steam outlet pipe 2, outlet pipe 4 the other ends are communicated with water pump 5, water pump 5 draw two waste pipes, 8, two waste pipes 8 also respectively with the water route of suction tude 1, the water route of steam outlet pipe 2 is communicated with.
As shown in Figure 3, the process of tail gas clean-up is: the waste gas of diesel engine enters water washing box 7 by suction tude 1, and at this moment five showers 6 just spray waste gas, except the cooled exhaust air temperature, goes back the SO in the scavenging
2With CH formaldehyde, make these two kinds of harmful gases soluble in water, once adorn water 420kg in the water washing box 7, after working one day, this water is acidic liquid, and corrosivity is very strong, so change water every day one time, all metallic material that contact with water all are acid-resistant stainless steel (1Cr18Ni9Ti).
The cooling method of tail gas is: this locomotive by water washing box 7, suction tude 1 and and the intake pipe 3 that is connected lower the temperature.Water enters five showers 6 from the intake pipe 3 of water washing box 7, a lot of hole for water sprayings 61 are arranged on the shower 6, water sprays from each hole for water spraying 61 respectively after entering shower 6, some hole for water sprayings 61 up mainly are to be used for cooling water tank-washer 7 top skins, and other hole for water spraying 61 mainly is to be used for SO in cooled exhaust air and the scavenging
2With CH formaldehyde.Suction tude 1 and steam outlet pipe 2 all have water jacket, the water flowing of middle ventilation outer course, and purpose is the waste gas of cooling diesel engine discharge and makes outlet pipe appearance temperature be no more than 150 ℃.
As shown in Figure 3, the temperature-fall period of tail gas is: be connected by outlet pipe 4 between the water outlet 41 of water washing box 7 and the water pump 5, water just comes out to enter water pump 5 from water washing box 7 water outlets 41, and the water in the water pump 5 is by 4 fens two-way of outlet pipe, and first via water is to enter a waste pipe 8 by outlet pipe 4; The second road water is to enter another waste pipe 8 by outlet pipe 4.Two waste pipes 8 also are communicated with suction tude 1, steam outlet pipe 2 respectively, this two path water is by the suction tude 1 of two band water jackets and steam outlet pipe 2 enters water washing box 7 from two intake pipes 3 water intake 31, be divided into five the tunnel again at water washing box 7 water intakes 31 and enter five showers 6 respectively, water sprays the back with regard to cooling water tank-washer 7 and waste gas by the hole for water spraying 61 of shower, has so just formed circulating water.After discharging, the waste gas of diesel engine just enters the suction tude 1 that has water jacket, at this moment the circulating water in the suction tude 1 is just forced cooled exhaust air, and make the outlet pipe surface temperature be no more than 150 ℃, just enter water washing box 7 by suction tude 1 waste gas, at this moment the exhaust gas temperature that is sprayed just sharply descends, owing to be added with air guide dividing plate 9 in the water washing box 7, so waste gas is to walk the S type in water washing box 7, last waste gas comes out from water washing box 7, enter steam outlet pipe 2, the water in steam outlet pipe 2 water jackets cools off once more to waste gas, guarantees that like this temperature is no more than 70 ℃ when waste gas is discharged at last, make the vent systems appearance temperature of locomotive integral body be no more than 150 ℃, meet requirement of explosion proof.
