Embodiment 1

[0036] Heat the alcohol-concentrated waste liquid containing 45% of the total solids to 60°C, spray it with a high-pressure spray gun, so that the compound fertilizer is fully covered by the misty coating agent-molasses alcohol waste liquid before entering the coating cylinder, and then follow the Add anti-caking additives (purchased from powdered anti-caking materials produced by Guangdong New Lvyuan Chemical Co., Ltd.) to 1.5% of the total amount of granular fertilizers to allow them to fully adhere to the surface of fertilizer particles in the rotary coating drum, and the granular fertilizers are then After cylindrical polishing and cooling, the coating anti-knot treatment is completed.

Embodiment 2

[0038] Heat the concentrated alcohol waste liquid containing 65% of the total solids to 80°C, and spray it with a high-pressure nozzle, so that the compound fertilizer is fully covered by the misty coating agent-molasses alcohol waste liquid before entering the coating cylinder, so that it Fully adhere to the surface of the fertilizer granules in the rotary coating cylinder, and the granular fertilizer is polished and cooled by the cylinder to complete the coating and anti-knot treatment.

Embodiment 3

[0040]Heat the alcohol concentrated waste liquid containing 55% of the total solids to 70°C, spray it with a high-pressure nozzle, so that the compound fertilizer is fully covered by the misty coating agent-molasses alcohol waste liquid before entering the coating cylinder, and then follow the 0.5% of the total amount of granular fertilizer is added with anti-caking additive talc powder to allow it to fully adhere to the surface of fertilizer particles in the rotary coating cylinder. After the granular fertilizer is polished and cooled by the cylinder, the anti-caking treatment of coating is completed.

Abstract

The invention relates to an anti-blocking compound fertilizer and a preparation method of the compound fertilizer; the anti-blocking compound fertilizer is prepared by coating molasses alcohol waste liquid concentrate on the surface of the compound fertilizer; the organic substances in a molasses alcohol waste liquid are fully used for covering the surface of the granulated fertilizer, so that the fertilizer salt base is avoided being separated out, and the double effects of enveloping and preventing blocking can be achieved; meanwhile, the mineral elements in the molasses alcohol waste liquid is fully used for preparing the fertilizer and can be absorbed by crops, so that the double effects of environmental management and refuse reclamation can be achieved; and the method opens a new way for the comprehensive treatment of the molasses alcohol waste liquid.

Description

technical field [0001] The invention belongs to the field of data reuse, and in particular relates to a compound fertilizer in which molasses alcohol concentrated waste liquid is used for compound fertilizer coating so as to realize anti-caking and a preparation method thereof. Background technique [0002] Molasses alcohol waste liquid refers to the organic waste liquid with high concentration, deep color and high acidity, which is discharged after the fermented mash is distilled out of alcohol in the primary tower, using molasses, a by-product of sugar factory sugar production, as raw material. For every 1 ton of alcohol produced Discharge 13-15 tons of waste liquid, and every 1 ton of alcohol produced from the waste mash produces as much as 0.6-1 ton of oxygen-consuming organic matter, with high CODcr and BOD5 contents, which will cause serious pollution to the environment if discharged directly. In addition, the waste liquid contains about 10% of various organic substanc...
