Further improvement of the present invention, in particle drying and granule cooling process, will produce in drying machine and cooler
Gas phase tail gas by pipeline import expansion chamber, then by tail gas by water dust scrubber filtration after emptying, by expansion chamber to gas
Phase tail gas is settled, by solid dirt settle down again through water dust scrubber filtration after empty, reduce compound fertilizer life
Pollution of the dust produced during product to air.
Further improvement of the present invention, in gradation flow process, the bulk material of unfinished pelletize is delivered to broken
Crushed in machine, the material after crushing is delivered in batch mixer and recycles；By less than standard particle diameter granule or
Person's fine-powdered feedstock transportation is recycled into comminutor.Compared with prior art, undesirable granule is collected
Recycling, greatly reduces production cost, improves production efficiency.
Further improvement of the present invention, in feed proportioning flow process, is stored in the sulfuric acid concentration in sulfuric acid storage tank more than 65%,
Sulfuric acid concentration Jing after the dilution of sulphuric acid dilution trap is 15%-25%, and the sulphuric acid for having diluted quantified in being drained to sulfuric acid gauge tank
5 are pressed with the ammonia in ammonia storage tank:1 ratio mixes.
Further improvement of the present invention, the original, ratio of adjuvant in raw material stirring flow process be：The carbamide of 20～45 weight portions,
The phosphate cpd of 20～79 weight portions, the sulfate of 20.5～48 weight portions, the Borax of 0.1～1.5 weight portion, 0.1～2 weight
The polyacrylate compound of the seven water ammonium molybdates and 0.5～15 weight portion of amount part.
Further improvement of the present invention, the original, ratio of adjuvant in raw material stirring flow process be：The carbamide of 30 weight portions, 40 weights
The phosphate cpd of amount part, the sulfate of 25 weight portions, the Borax of 1 weight portion, seven water ammonium molybdates of 1 weight portion and 3 weight portions
Polyacrylate compound.
Beneficial effects of the present invention, compared with prior art, the compound fertilizer production technology of present disclosure was to producing
The waste gas produced in journey has carried out filtration treatment, reduces pollution of the waste gas to environment, meets national environmental protection policy requirements, together
When, undesirable granule is collected recycling by the present invention, greatly reduces production cost, improves production effect
Rate.
