Abstract
The invention relates to the technical field of fertilizer processing and in particular relates to a production method of a compound phosphate fertilizer. The compound phosphate fertilizer is produced from raw materials such as phosphorus-containing waste ash, pot ash, ferrous sulfate, calcium superphosphate, a white fertilizer and filter cakes, the used raw materials are all industrial wastes or byproducts and are sufficient and low in cost, and the produced compound phosphate fertilizer is stable in quality, meets the national standards, is suitable for neutral soil and acidic or alkaline soil, and has a very remarkable application effect in cold and hot regions; three wastes are used as production raw materials, so that the wastes are turned into wealth, resources and energy are saved, enterprises and farmers are benefited, and the farmers are guided to gradually give up the dependence on a chemical fertilizer and a hormone fertilizer under the circumstance that the compound phosphate fertilizer is good in quality and low in price; the industrial three wastes are utilized, so that the production costs of enterprises can be reduced and the agricultural sustainable development is consolidated and promoted.
Description
Technical field
The present invention relates to fertilizer processing technique field, is a kind of production method of compound phosphate fertilizer specifically.
Background technology
The technique of producing at present calcium superphosphate has two kinds:
(1) utilize the phosphorus ore of >=24% content to add water for ball milling and become moisture 28%~33%, fineness is mixed by 3:1 with the sulfuric acid of 98% concentration at 88~98 object ore pulps, and slaking 8 hours must calcium superphosphate;
(2) utilize the phosphorus ore oven dry ball milling of >=24% content to become fineness to mix by 3:1 with the sulfuric acid of 70% concentration at 88~98 object breezes, slaking obtains calcium superphosphate for 24 hours;
Above two kinds of products, except containing effective P
2o
5>=12%, moisture≤15%, outside free acid≤5.5%, also containing effective sulphur 3%~5%, the production technique of this kind of calcium superphosphate is easily subject to the impact of weather, electricity, water, mechanical fault in process of production, and moisture and free acid are difficult to control, and workman does over again often, easily super quality standard of harm element heavy metal lead, twice even can exceed standard.
(3) patent publication No. is that " CN103253996A ", denomination of invention are " a kind of production technique of compound phosphate fertilizer ", because product free acid content is very low or do not contain, this patent of invention product is mainly applicable to weather condition cold, edaphic condition is neutrality or acid soil.But in hotter or meta-alkalescence soil, result of use is not obvious at weather; And along with a large amount of uses of chemical fertilizer, a lot of soils are all meta-alkalescences, therefore have the not good problem of result of use.
Summary of the invention
The object of the invention is the problem for above-mentioned existence, a kind of production method of compound phosphate fertilizer is provided, and the method is taking industrial phosphorus-containing waste as raw material, and the fertilizer of producing can meet the growth demand of plant, reduce the production cost of enterprise, there is the effect of energy-conserving and environment-protective simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of production method of compound phosphate fertilizer, and it comprises the following steps:
