Pond, records pH value according to detector, carries out secondary neutralization with alkali liquor injection device, makes pH stable within the scope of suitable.
The beneficial effects of the utility model are,
1. the gas entering air is the lowest containing acid number, meets the discharge standard of national regulation.
2. improve working environment, reduce acid gas to person health and the destruction of atmospheric environment.
3. pair acid gas carries out twice process, had both processed acid gas, and had neutralized again the waste liquid dissolving in acid gas, make the pH stable of waste liquid
Within the scope of suitably, waste liquid is used doing his after both can collecting, it is also possible to as the sewage discharge meeting pH value standard.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 is acid room, pond, and 2 is acid pond, and 3 is waste liquid pool, and 4 is alkali liquor injection device, and 5 is pH value detector, and 6 is spray
Mouth, 7 is except mist plate, and 8 is Bauer ring flat-plate, and 9 is funnel, and 10 is lye pump, and 11 is chimney, and 12 is air-introduced machine.
Detailed description of the invention
A kind of acid gas processing system, waste liquid pool 3, the upside including case type acid room, pond 1, be located in acid room, pond 1 are provided with
The chimney 11 that the air-introduced machine 12 that the spray column of gas outlet is connected by pipeline with gas outlet connects with air-introduced machine 12, described acid
Having two plant produced working acid ponds 2 in room, pond 1, acid room, pond 1 is by being provided with the pipeline communication of exhaust fan in spray column
Downside, the inside bottom of described spray column is provided with the funnel 9 that the periphery for collecting waste liquid is high, middle part is low, and described funnel hole leads to
Crossing and carry valvular pipeline communication to waste liquid pool 3, described spray column includes the two-layer spray that lye pump 10 is connected with lye pump 10
Drench layer, be positioned at gas outlet except mist plate 7, five spirals that described each spraying layer includes shower, is distributed on shower
Cone nozzle 6, be positioned at five layers of Bauer ring flat-plate 8 on the downside of shower, nozzle 6 ejection water smoke cross section be sector, segment angle
Degree is 80 °, and atomizing particle is 50 m；It is provided with in described waste liquid pool 3 for neutralizing the acid alkali liquor injection device 4 of waste liquid and pH value
Detector 5, described alkali liquor injection device 4 is syringe and the alkali liquor pipeline connecting syringe, is positioned at the alkali liquor outside acid room, pond 1
