The liquid entrance of circulating pump and recovery tower connects to form ammoniacal liquor cycle.
In said program, the material residue in reaction kettle, which is pumped by hose in plate and frame filter press, carries out press filtration.
Further, the clear water after plate and frame filter press press filtration respectively enters absorption tower circulating slot by pipeline, recovery tower follows
In annular groove.
Further, the liquid outlet of recovery tower is also connect with absorption tower circulating slot.
Further, the gas vent in ammonium sulfate tank, absorption tower circulating slot, recovery tower circulating slot with the gas on absorption tower
Import connects.
Preferably, it is additionally provided with heat exchanger between absorption tower circulating slot and absorption tower liquid-inlet.
Further, absorption tower circulating slot is also connected with delivery pump and the ammonium hydroxide that content is 20% is removed conversion ammonium carbonate processed.
The beneficial effects of the utility model are：Quantitative that ammonium sulfate saturated solution is added in reaction kettle, side is stirred in a kettle
It mixes side and is gradually added calcium oxide, the ammonia for reacting generation enters absorption tower, and ammonia is by the big portion of the weak aqua ammonia recycled in absorption tower
Divide and absorb, ammonium hydroxide of the concentrated ammonia liquor for lead sulfate conversion of 20% or more ammonia content is made.Also a small amount of ammonia not absorbed enters
Recovery tower, a small amount of ammonia is recycled completely by the clear water recycled in recovery tower, and the weak aqua ammonia that low concentration is made is dense for absorption tower system
Ammonium hydroxide is used.Residue obtains gypsum filter cake after press filtration in reaction kettle, and filtrate (clear water) is recycled to system for ammonium hydroxide processed.System
Design closed micro-negative pressure operation, safety and environmental protection.
Description of the drawings：
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode：
Refering to Figure 1, being the structural schematic diagram of the preferred embodiment for the utility model, the utility model is one kind
For the ammonia regeneration circulator of lead plaster conversion, mainly followed including reaction kettle 1, absorption tower 2, recovery tower 3, ammonium sulfate tank 4, absorption tower
The feed liquid of annular groove 5, recovery tower circulating slot 6, the ammonium sulfate tank 4 is drawn into reaction kettle 1, and reaction kettle 1 passes through lime bucket and spiral shell
It revolves feeder and adds calcium oxide, the ammonia that calcium oxide is generated with feed liquid is carried out by absorption tower 2, recovery tower 3 successively by pipeline
Recovery processing, the absorption tower circulating slot 5 are connect to form ammoniacal liquor cycle with the liquid entrance on absorption tower 2 by circulating pump, be led to
Cross weak aqua ammonia absorbed in absorption tower 2 ammonia be made ammonia content 20% or more concentrated ammonia liquor for lead sulfate conversion ammonium hydroxide used in, and
Recovery tower circulating slot 6 connect to form ammoniacal liquor cycle with the liquid entrance of recovery tower 3 by circulating pump, i.e., will be a small amount of by clear water
Complete safety is not absorbed to be dissolved, and diluted aqua ammonia recovery is formed.Meanwhile the liquid outlet of recovery tower 3 is also recycled with absorption tower
Slot 5 connects, and being re-circulated into absorption tower 2 in dilute ammonia that recovery tower 3 recycles produces concentrated ammonia liquor, and ammonia is made to efficiently use repeatedly.
