Abstract
The invention relates to a water saving system of a tail gas absorption process. The water saving system comprises a lime watering treater, a lime emulsion tank, a circulating tank and a press filter, wherein water supply is added into the lime watering treater, lime is added into the lime watering treater at the same time, then a lime emulsion is generated and enters the lime emulsion tank; the lime emulsion in the lime emulsion tank is pumped into the circulating tank to wash residual SO2 in flue gas, and then pressed and filtered by the press filter, so that a solid part is changed into a filter cake and discharged; filtering liquid is fed into the lime watering treater for cycle use through a pipeline. The water saving system of the tail gas absorption process is capable of recycling the purified filtering liquid fully, reducing water resource waste and enhancing economic benefit of an enterprise.
Description
Technical field
The present invention relates to nonferrous metallurgy field, be specially a kind of tail and inhale operation water-saving system.
Background technology
In nonferrous metallurgy field, 10% lime slurry that tail is inhaled operation employing washs SO remaining in flue gas
2, at tail, inhaling operation lime slurry needs water to prepare, the about 40-70m of per tour water
3water, the lime slurry preparing is squeezed in circulating slot and is used.
Fig. 1 is that tail of the prior art is inhaled process flow, and running water is joined in lime watering treater, adds lime in lime watering treater simultaneously, produces lime slurry and enters into milk of lime liquid bath, produces lime-ash in lime watering treater simultaneously; Lime slurry in milk of lime liquid bath is driven into the SO that washs remnants in flue gas in circulating slot
2, after filter press press filtration, arrange outward afterwards.
Tail is inhaled operation when normal production, for preparing lime milk liquid, and the about 40-70m of per tour water
3water, has wasted a large amount of water resources, and water resource cannot be recycled.
Summary of the invention
The object of the present invention is to provide a kind of tail to inhale operation water-saving system, to reduce the waste of water resource.
The technical solution adopted for the present invention to solve the technical problems is:
Inhale an operation water-saving system, comprise lime watering treater, milk of lime liquid bath, circulating slot, filter press, it is characterized in that, running water is joined in lime watering treater, in lime watering treater, add lime simultaneously, produce lime slurry and enter into milk of lime liquid bath; Lime slurry in milk of lime liquid bath is driven into the SO that washs remnants in flue gas in circulating slot
2, passing through afterwards filter press press filtration, solid portion becomes filter cake discharges, and cleaner liquid is sent in lime watering treater and recycles through piping.
Tail of the present invention is inhaled operation water-saving system, can fully recycle the cleaner liquid after purified treatment, reduces water resource waste ，Wei enterprise and increases economic benefit.
Accompanying drawing explanation
Fig. 1 is that tail of the prior art is inhaled operation handling process.
Fig. 2 is the handling process that tail of the present invention is inhaled operation water-saving system.
The specific embodiment
As shown in Figure 2, a kind of tail is inhaled operation water-saving system, comprises lime watering treater, milk of lime liquid bath, circulating slot, filter press, it is characterized in that, running water is joined in lime watering treater, adds lime in lime watering treater simultaneously, produces lime slurry and enters into milk of lime liquid bath; Lime slurry in milk of lime liquid bath is driven into the SO that washs remnants in flue gas in circulating slot
2, passing through afterwards filter press press filtration, solid portion becomes filter cake discharges, and cleaner liquid is sent in lime watering treater and recycles through piping.Closed cycle of the present invention, inner digestion, has saved valuable water resource, alleviates downstream production, cost and pressure simultaneously.
