Abstract
The invention belongs to the field of fertilizer industry, and relates to a production method of granulated calcium ammonium nitrate. The method comprises the steps that: dilute nitric acid and calcium carbonate are subjected to a neutralization reaction; a calcium nitrate solution is subjected to pres-filtration; the calcium nitrate liquid is mixed with an ammonium nitrate liquid; press-filtration, concentration, granulation, packaging, and inspecting are carried out; and the obtained granulated calcium ammonium nitrate is stored. The method provided by the invention has the advantages of novel design, unique method, low production cost, easy operation, and high practicality. The method can be popularized.
Description
Technical field
What the present invention relates to is a kind of production method of granulation calcium ammonium nitrate, belongs to fertilizer industry.
Background technology
At present, the drawback that has ammonium nitrate and calcium indissoluble in the fertilizer industry production.There is the large problem high with input of consumption and use simultaneously two kinds of fertilizer.
Summary of the invention
The invention provides a kind of production method of granulation calcium ammonium nitrate, can overcome above-mentioned drawback.
The present invention realizes by the following technical solutions; A kind of production method of granulation calcium ammonium nitrate, it comprises rare nitric acid, calcium carbonate neutralization reaction, the ca nitrate soln press filtration, nitrocalcite liquid, ammonium nitrate solution mix, and press filtration is concentrated, granulation, packing, check warehouse-in is characterized in that: the production method of granulation calcium ammonium nitrate is the rare nitric acid of 30-60% and 92% calcium carbonate to be packed into neutralization reaction generates ca nitrate soln in the stainless steel reactor; Ca nitrate soln is injected plate-and-frame filter press to carry out press filtration and generates 80% nitrocalcite liquid; 80% nitrocalcite liquid and 20-30% ammonium nitrate solution are injected agitator to be mixed; With nitrocalcite and the press filtration of ammonium nitrate mixed solution process plate-and-frame filter press; Liquid after the press filtration adds 130 ℃ after injecting vaporizer--and 150 ℃ of steam always 〉=15% are condensed into N, the calcium ammonium nitrate of Ca 〉=18%; Calcium ammonium nitrate after steam is concentrated injects granulation in the spray granulating machine; Product behind the granulating and forming flows into the packaging machine weight packaging; After moulding product passed through experience in batches, the salable product warehouse-in.
Advantage of the present invention and positively effect:
Modern design, method is unique, and production cost is low, and easy to operate.Has practicality, generalization.
