Embodiment 1

[0023] A kind of method utilizing by-product sulfuric acid to produce agricultural calcium magnesium fertilizer, comprises the following steps:

[0024] 1) Use the vertical feeder 1 to place a certain proportion of by-product sulfuric acid and the mixture of calcined dolomite or magnesite and marble ore in the mixing tank 2 for reaction. .

[0025] 2) Cool down to below 60 degrees after the reaction, add a certain amount of borax, zinc sulfate, and then add the mixture of microorganisms and organic matter.

[0026] 3) Then it is fully mixed through the mixing tank 2, and the material is exported to the conveyor 4 after the mixing is completed.

[0027] 4) The material is then introduced into the crusher 6 through the conveyor 4 for crushing, and after the crushing is completed, the material is introduced from the crusher 6 into the granulation feeder 7 .

[0028] 5) The material is introduced into the granulator 9 through the granulation feeding machine 7 for uniform granula...

Abstract

The invention relates to the technical field of water-soluble fertilizer production, and discloses a method for producing an agricultural calcium-magnesium fertilizer by using byproduct sulfuric acid.The method is characterized by comprising the steps of putting a certain proportion of byproduct sulfuric acid and calcined dolomite ore or a mixture of magnesite and marble ore into a stirring tankfor reaction by using a vertical feeding machine, cooling to the temperature of 60 DEG C or below after the reaction is finished, adding a certain amount of borax and zinc sulfate, and adding a mixture of microorganisms and organic matters; According to the method for producing the agricultural calcium-magnesium fertilizer by utilizing the byproduct sulfuric acid, the byproduct sulfuric acid and calcined dolomite ore or the mixture of magnesite and marble ore in a certain proportion are put into the stirring tank for reaction by using the vertical feeding machine, the temperature is cooled to60 DEG C or below after the reaction is finished, a certain amount of borax and zinc sulfate are added, then the mixture of microorganisms and organic matters is added, and the produced product is rich in calcium, magnesium, zinc, iron, boron, manganese, sulfur and active bacteria, and has obvious effects of disease resistance, stress resistance, growth promotion and yield increase.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a method for producing agricultural calcium-magnesium fertilizer by using by-product sulfuric acid. Background technique [0002] Calcium-magnesium fertilizer uses advanced calcium-magnesium chelation technology to greatly enhance the adhesion and adsorption. It contains water-soluble active calcium and has a high absorption rate. It has a good effect on symptoms such as disease and bitter pox, and can prolong the freshness and storage period of melons and fruits. It contains active magnesium and nitrate nitrogen, which can greatly promote the photosynthesis and respiration of crops, and promote the synthesis of chlorophyll. The leaves quickly turn green and thicken, which has a good effect on the prevention and treatment of yellow leaf disease. [0003] At present, the volume of by-product sulfuric acid produced by various domestic industries is very large. The cu...
