Low-energy-consumption environment-friendly production process of organic-inorganic compound fertilizer and granular water-soluble fertilizer

Abstract

The invention belongs to the technical field of fertilizer preparation, and provides a low-energy-consumption environment-friendly production process of an organic-inorganic compound fertilizer and agranular water-soluble fertilizer. The low-energy-consumption environment-friendly production process comprises the following steps that raw materials are weighed for use according to a production formula; quantitative microelements and an effect increasing and drought resisting agent are added into the raw materials, full mixing is carried out, and the mixed raw materials are obtained; the mixedraw materials are subjected to extruding pelleting; after screening is carried out, secondary extruding pelleting and finished product polishing are carried out; polished finished product particles are subjected to large-air-amount cold drying or steam drying, and finished products are obtained after packaging is carried out. The technical problem that in the preparation process of an existing fertilizer, energy consumption is high, and the pollutant emission amount is large is solved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation technology, and relates to a low energy consumption and environment-friendly production technology of organic-inorganic compound fertilizer and granular water-soluble fertilizer. Background technique [0002] Compound fertilizers refer to functional or non-functional organic-inorganic compound fertilizers. Compound fertilizers are a general term for fertilizers made by mixing several simple fertilizers or simple fertilizers with chemically synthesized compound fertilizers. Water-soluble fertilizers generally refer to macronutrients. Granular water-soluble fertilizers, the three types of fertilizers require high energy consumption and large pollutant emissions during the preparation process. Nowadays, in order to create a good living environment, reduce air pollution, and reduce the use of chemical fertilizers, the country vigorously promotes energy conservation and environmental prot...

[0002] Compound fertilizers refer to functional or non-functional organic-inorganic compound fertilizers. Compound fertilizers are a general term for fertilizers made by mixing several simple fertilizers or simple fertilizers with chemically synthesized compound fertilizers. Water-soluble fertilizers generally refer to macronutrients. Granular water-soluble fertilizers, the three types of fertilizers require high energy consumption and large pollutant emissions during the preparation process. Nowadays, in order to create a good living environment, reduce air pollution, and reduce the use of chemical fertilizers, the country vigorously promotes energy conservation and environmental protection. Therefore, the use of fertilizers The preparation industry has caused a certain impact. The present invention has developed a low energy consumption and environment-friendly production suitable for humic acid type (functional) organic-inorganic compound fertilizers, compound fertilizers and macroelement full water-soluble fertilizers (granules). It has the advantages of high fertilizer utilization rate, low production energy consumption, low production cost rate and low emission, and solves the technical problems of high energy consumption and large pollutant discharge in the fertilizer preparation process
