Problems solved by technology

[0004] Most of the existing compound fertilizers are produced by rolling and agglomerating with granulators. This process requires the addition of water, and the fertilizer granules after agglomeration must be dried to dry the water in order to For packaging and storage, it will consume more energy for drying operations

Abstract

The invention belongs to the technical field of compound fertilizer production, and relates to a production method and device of an organic-inorganic compound fertilizer. The method comprises the following steps: adding powdery weathered coal based on the traditional granulated potassium sulfate type compound fertilizer production, and carrying out acid activation treatment, wherein fertilizer granules are dried by heat released by the dilution of sulfuric acid in the production process, thereby avoiding the additional drying process and saving the energy. The product provided by the invention has the advantages of reasonable proportioning and balanced nutrition, and has the functions of improving the soil, stimulating the growth of root systems of plants and enhancing the utilization rate of the fertilizer, thereby being a novel sulfur-based compound fertilizer rich in organic substances and multiple nutrient elements.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, and relates to a production method and equipment of an organic-inorganic compound fertilizer. Background technique [0002] At present, compound fertilizers do not contain organic matter, and the utilization rate of fertilizers is low. Long-term use may easily cause soil compaction. Some potassium sulfate compound fertilizers containing organic matter cannot be absorbed by plants due to the poor activity of organic matter. [0003] Weathered coal is a coal seam that is exposed on the surface or buried in the shallow part. It has been in contact with water and air for a long time, and has undergone long-term oxidation and hydrolysis weathering, making the coal loose and brittle, with light color and increased humidity. Great changes have taken place, and its chemical and physical properties have undergone extremely obvious changes, forming more humic acid. Humic acid is co...
