Drenching ammonia gas generating device and produce the ammonia in water dust scrubber side by side, ammonia is dissolved among the waste water under shower nozzle spray；
2) by periodic detection, when the nitrogen content in withdrawal liquid reaches the content that fertilizer production needs, every liter more than 20 grams, beat
Open the conduction oil in pond or steam-heating pipe, conduction oil or steam, by the heat pipe that adds at the bottom of pond, water is heated to 90-100
Degree, adds sodium hydroxide or pH value is adjusted between 3-12 by sulphuric acid；
3) then according to every cube of weathered coal at least adding more than 100--500 kilogram or peat react 1-2 hour, react into
After humic acid liquid, then turn off the second transfer pipeline and lead to the valve of water dust scrubber, open and be connected on the second transfer pipeline
Valve on 3rd transfer pipeline road, enters humic acid liquid pump in evaporation concentration equipment；
4) open heating oil pipe and aerator, dispelled by unnecessary moisture in hot and humid liquid and vapor away, evaporation and concentration
After material drop in reaction tank, it is to avoid the too high viscous cylinder of denseness, simultaneously open anti cleaner, when the moisture in liquid is low
In 40% or liquid manure separator fertilizer collecting bag in begin with a small amount of solids time, close the 3rd transfer pipeline valve, the company of opening
The 4th transfer pipeline valve being connected on the second transfer pipeline, the moisture humic acids pump less than less than 40% to vacuum dryer
In go, observed by inspection door, after the material of humic acids reach a certain height in vacuum equipment, turn off the 4th transfer pipeline valve,
Open the heat conduction fuel tap of vacuum dryer, control temperature and make in equipment at 50-100 degree, the motor opening vacuum equipment top
Stirring vane stirring humic acids, open vacuum pump, steam taken away, by observing the psychrometer on vacuum equipment,
When moisture is less than less than 20, turns off vacuum pump, open air relief valve, proportionally add potassium chloride, potassium sulfate, phosphorus by inspection door
Acid dihydride potassium, carbamide, ammonium chloride, ammonium sulfate, calcium superphosphate, MAP, Diammonium phosphate (DAP), calcium hydrogen phosphate, middle trace element enters
Row stirring, is opened bottoms material outlet, is transmitted into drum granulating or disk by transmission belt by the material prepared after stirring
Granulation Equipments causes granule, it is possible to is transmitted directly to disintegrating machine and smashes into powder, and finished product out is containing Remixed humic acid fertilizer.
