Problems solved by technology

[0007] In the above-mentioned CN201210379946.4 patent application, the solid content of the molasses alcohol waste liquid concentrate is limited to 45-65%, the viscosity is particularly large, and the total solid content Concentrating to a solid content of 45-65% requires very high heat energy, so there is still a problem of high energy consumption in the production of concentrated molasses alcohol waste liquid as fertilizer

Embodiment example 1

[0025] 40 kg of urea, 40 kg of monoammonium phosphate, 20 kg of potassium chloride, 10 kg of copper sulfate, and 590 kg of fermented and decomposed organic raw materials such as sugar factory filter mud and cassava residue, after being crushed, the various raw materials are transported into granulation On the conveyor belt in front of the machine, spray 150 kg of molasses alcoholic fermentation liquid with a water content of 95%. Among the various fertilizer raw materials mentioned above, the crystal nuclei formed by the molasses alcohol fermentation liquid and the short fibers of organic raw materials gradually expand the granules and complete the granulation. Standard spherical organic fertilizer products are put into storage, and unqualified products are returned to the crusher for crushing and granulation.

Embodiment example 2

[0027] 50 kg of urea, 100 kg of monoammonium phosphate, 50 kg of potassium chloride, 10 kg of zinc sulfate, and 490 kg of 5 kinds of fermented and decomposed organic raw materials such as sugar factory filter sludge, bagasse, sugarcane pith, sugarcane leaves, and cassava bagasse. After the raw materials are crushed, they are sent to the conveyor belt in front of the granulator, sprayed with 150 kg of molasses alcohol fermentation liquid with a water content of 90%, and when various raw materials are transported to the disc machine for mixing and granulation, the Spray 150 kg of alcohol fermentation liquid into the aforementioned various fertilizer raw materials, and use molasses alcohol fermentation liquid as a binder for granulation. After drying, sieving, weighing, packaging, and inspection, the product can be made into granules conforming to 884-2012 national standard for bio-organic fertilizer products.

Embodiment example 3

[0029] 100 kg of urea, 150 kg of ammonium chloride, 50 kg of monoammonium phosphate, 200 kg of calcium magnesium phosphate fertilizer, 50 kg of potassium chloride, 5 kg of copper sulfate, 10 kg of zinc sulfate, 10 kg of Liyuanbao synergist and chicken manure 325 kg of fermented and decomposed organic raw materials, corn stalks, and cassava residues, are transported to the ring die granulator by a conveyor belt for granulation. Before the above fertilizer raw materials are transported into the ring die granulator, spray water content 100 kg of 80% molasses alcoholic fermentation liquid is made into a spherical organic-inorganic compound fertilizer product through a ring die granulator. The granulated product is dried, screened, weighed, packaged, inspected, and stored. , can obtain multi-nutrient organic-inorganic compound fertilizer products containing medium and trace elements and fertilizer synergists that meet the national standard of GB18877-2009.

Abstract

A method for producing fertilizer through dilute molasses alcohol wastewater is characterized in that an alcohol wastewater spraying device is arranged above a raw material conveying belt in a fertilizer production line and sprays alcohol wastewater discharged at the tail end of the molasses alcohol distilling process on various fertilizer raw materials on the raw material conveying belt, the molasses alcohol wastewater and the various fertilizer raw materials enter a granulation device after being mixed, or molasses alcohol is sprayed on the molasses alcohol wastewater and the various fertilizer raw materials again on the granulation device, the molasses alcohol wastewater and the various fertilizer raw materials are bonded with short fibers in organic raw materials so that the diameter of particles can be increased in the rolling process of the granulation device, and then fertilizer granulation is achieved. By means of the method, dilute molasses alcohol fermentation liquor can be utilized cleanly without concentrating the molasses alcohol fermentation liquor in advance, and concentration equipment and energy are saved.

Description

technical field [0001] The invention relates to a fertilizer granulation method containing organic raw materials, which belongs to the fields of sugar factory waste application and fertilizer production. Background technique [0002] In the common fertilizer production process, the method of water or sulfuric acid granulation is usually used. This method is formed by adding water or sulfuric acid to the mixed fertilizer raw materials, and using some of the inorganic materials such as urea and monoammonium phosphate to dissolve in the dryer. The viscous liquid gradually forms fertilizer granules, and the granulation equipment at the front end of the dryer has little effect on fertilizer granulation. This method not only wastes a large amount of resources, but also has a low granulation rate in fertilizer production, which pushes up the cost of fertilizer production. Especially in the production of formula fertilizers containing organic raw materials, the organic raw material...
