Technical Field

The invention relates to a high tower nitro compound fertilizer using mineral potassium fulvate for soil remediation, belonging to the technical field of agricultural fertilizers.

Background

With the continuous rise of global air temperature, particularly in dry air places or slightly high places, the fertilized soil is easy to dry, so that plants can hardly absorb dry fertilizers, and the nutrient utilization rate of the fertilizers is reduced. Meanwhile, the phenomena of soil hardening and salinization are more and more serious due to excessive use of various fertilizers, so that plants are difficult to grow healthily.

In addition, China has a large population, the average cultivated land area is very limited, the significance of protecting the existing cultivated land and improving and utilizing the obstacle soil is great; therefore, how to prepare a special fertilizer which has rich nutrient substances, coordinated and lasting release of nutrient elements, high utilization efficiency of fertilizer nutrients, no additional fertilizer or less additional fertilizer for one-time fertilization, soil property improvement and enhancement of stress resistance of crops such as drought resistance, cold resistance, disease resistance and the like becomes a technical problem to be solved at present.

Disclosure of Invention

FIG. 1 is a high tower nitro compound fertilizer using mineral potassium fulvate for soil remediation.

Wherein: 1. a high tower granulation nitro-compound fertilizer body, 2, a soil restoration layer, 3 and a moisture retention layer.

Detailed Description

As shown in figure 1, the high-tower granulated nitro-compound fertilizer comprises a high-tower granulated nitro-compound fertilizer body 1, a soil remediation layer 2 and a moisturizing layer 3, wherein the high-tower granulated nitro-compound fertilizer body 1 is wrapped by the soil remediation layer 2, and the soil remediation layer 2 is wrapped by the moisturizing layer 3.

The processing steps of the high tower granulated compound fertilizer using mineral source potassium fulvate for soil remediation are as follows:

A. preparing a high-concentration ammonium nitrate solution: the ammonium nitrate solution generated by neutralizing ammonium nitrate is pumped into a high tower after reaching the concentration of more than 95 percent through first-stage evaporation, and then is prepared into the ammonium nitrate solution with the temperature of 175 ℃ and more than 99 percent under the gas stripping and evaporation effects of high-temperature air with the temperature of 170 ℃ and saturated steam with the pressure of 1.3MPa through second-stage evaporation, and the ammonium nitrate solution automatically flows into a high-position melting tank

B. Mixing potassium: sending the ammonium nitrate solution into a first mixing reaction tank from a melting tank, then adding potassium sulfate and ammonium sulfate into the first mixing reaction tank, and mixing with the molten ammonium nitrate at the temperature of 155-160 ℃;

C. mixing phosphorus: the mixed materials in the first mixed reaction tank flow into a second mixed reaction tank, and then monoammonium phosphate is added into the second mixed reaction tank and mixed with the mixed materials in the first mixed reaction tank at the temperature of 145-150 ℃ to obtain mixed molten slurry;

D. granulating and molding in a high tower; spraying the homogeneous mixed liquid into a granulation tower through a differential granulation nozzle of the high tower to complete granulation; and then cooling, sieving by a coarse sieve, sieving by a fine sieve, coating (adding mineral source potassium fulvate and corncob powder into a coating roller), and finally packaging to obtain a finished product.
