Preferably, described alkali lye supervisor is provided with pump.
Preferably, described caustic wash tower comprises one-level caustic wash tower, secondary caustic wash tower and three grades of caustic wash towers, the air inlet of one-level caustic wash tower is connected with pickling flue gas leading, the gas outlet of one-level caustic wash tower is connected by the air inlet of downtake pipe with secondary caustic wash tower, the gas outlet of secondary caustic wash tower is connected by the air inlet of second exhaust pipe with three grades of caustic wash towers, and the gas outlet of three grades of caustic wash towers is connected with buffering settling vat by the 3rd blast pipe; Downtake pipe and second exhaust pipe are provided with blower fan.
Preferably, be provided with activated carbon adsorption layer in buffering settling vat, the port of the 3rd blast pipe is through activated carbon adsorption layer.
During work, the acid waste gas that diadust pickling produces enters one-level caustic wash tower, secondary caustic wash tower and three grades of caustic wash towers in turn by pickling flue gas leading and downtake pipe, second exhaust pipe, lye pump in alkali lye pond is beaten to alkali lye supervisor and alkali lye arm, finally enter in one-level caustic wash tower, secondary caustic wash tower and three grades of caustic wash towers respectively, and spray washing is carried out to the acid waste gas in tower, in and acid waste gas.Finally, through in alkali lye and after waste gas to enter buffering settling vat from the 3rd blast pipe, waste gas sedimentation in buffering settling vat, gaseous state acid solution in waste gas and alkali lye collide and liquefaction of condensing mutually, be separated with waste gas, waste gas, through the adsorption-edulcoration of activated carbon adsorption layer, is discharged outside to from the steam vent at buffering settling vat top; Alkali lye after spray is flowed in alkali lye pond by alkali lye return duct and recycles.
Meanwhile, in order to prevent waste gas discharge capacity excessive, directly overflowing from the import department of buffering settling vat, cannot sedimentation effectively be carried out, so arrange retaining hood on the 3rd blast pipe of buffering settling vat import department.If waste gas is when the quick import department from buffering settling vat overflows in a large number, the stop returning being subject to retaining hood enters buffering settling vat and carries out sedimentation.
The utility model compared with prior art, tool has the following advantages: structure is simple, by alkali lye, spray neutralization is carried out to the acid waste gas that diadust pickling produces, retaining hood coordinates buffering settling vat to carry out sedimentation removal of impurities again to the waste gas after neutralization simultaneously, and the waste gas after final process meets environment protection emission requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of diadust pickling emission-control equipment in detailed description of the invention;
Be labeled as in figure: pickling flue gas leading 1, one-level caustic wash tower 2, secondary caustic wash tower 3, three grades of caustic wash towers 4, retaining hood 5, buffering settling vat 6, steam vent 7, alkali lye pond 8, alkali lye supervisor 9, alkali lye arm 10, pump 11, alkali lye return duct 12, downtake pipe 13, second exhaust pipe 14, the 3rd blast pipe 15, blower fan 16.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, diadust pickling emission-control equipment, described device comprises one-level caustic wash tower 2, secondary caustic wash tower 3 and three grades of caustic wash towers 4, the air inlet of one-level caustic wash tower 2 is connected with pickling flue gas leading 1, the gas outlet of one-level caustic wash tower 2 is connected with the air inlet of secondary caustic wash tower 3 by downtake pipe 13, the gas outlet of secondary caustic wash tower 3 is connected with the air inlet of three grades of caustic wash towers 4 by second exhaust pipe 14, the gas outlet of three grades of caustic wash towers 4 is connected with buffering settling vat 6 by the 3rd blast pipe 15, downtake pipe 13 and second exhaust pipe 14 are provided with blower fan 16, activated carbon adsorption layer is provided with in buffering settling vat 6, the port of the 3rd blast pipe 15 is through activated carbon adsorption layer, 3rd blast pipe 15 of the import department of buffering settling vat 6 is provided with retaining hood 5, buffering settling vat 6 top is provided with several steam vent 7, described device also comprises alkali lye pond 8, alkali lye pond 8 and alkali lye are responsible for 9 and are connected, alkali lye supervisor 9 is provided with pump 11, alkali lye supervisor 9 is connected with alkali lye arm 10, alkali lye arm 10 is connected with the inlet of one-level caustic wash tower 2, secondary caustic wash tower 3 and three grades of caustic wash towers 4 respectively, and one-level caustic wash tower 2, secondary caustic wash tower 3 are connected with alkali lye pond 8 with alkali lye return duct 12 with the liquid outlet of three grades of caustic wash towers 4.
