Abstract

A method for multi-element formula fertilizer tower-type granulation with molasses alcohol fermentation liquor is characterized by comprising the following steps that the molasses alcohol fermentation liquor with the water content of 30%-90% is added into a reaction still, then macroelement, medium-element and microelement chemical fertilizer raw materials with the granularity of 0.1 mm-1.0 mm are put into the reaction still after being measured by batch charging equipment, stirring is carried out ceaselessly during heating, temperature is controlled at 100-140 DEG C, comprehensive slurry is conveyed to tower-type granulation equipment for slurry spraying granulation, during a free-falling process, particles are formed by cooling, then screening, packaging and inspecting are carried out, qualified products are put in storage, and returning materials go back to preheating mixed materials. According to the method, the molasses alcohol fermentation liquor is used for formula fertilizer tower-type granulation, multi-element formula fertilizer with macroelements, medium-elements, microelements and organic matter is produced, the method accords with the new fertilizer development direction, and meanwhile the molasses alcohol fermentation liquor can be used in a clean-environment-protecting-recycling mode.

Description

technical field [0001] The invention belongs to the field of resource recycling and comprehensive utilization and fertilizer production, and in particular relates to a method for using molasses alcoholic fermentation liquid in multi-component fertilizer tower granulation. Background technique [0002] The by-product of the sugarcane sugar industry chain is molasses alcohol fermentation liquid, which is a kind of high-concentration organic wastewater, and its random discharge will cause great environmental pollution. However, the solids in its dry matter contain 70% organic matter, and also contain sugar, protein, mineral elements, etc., and no other toxic and harmful substances have been detected. In view of this, the molasses alcohol fermentation liquid is applied to fertilizer production, returning to the land, improving soil organic matter, and fertilizing soil fertility. A consensus has been reached on the resource utilization of molasses alcohol fermentation liquid fer...
