Problems solved by technology

[0009] For example, alkali hydrolysis method, molten salt destruction method, supercritical water oxidation method; the principle of alkali hydrolysis method is to produce organic salts and inorganic salts through propellant or explosive and alkali hydrolysis reaction; the principle of molten salt destruction method is, Molten salts are carbonates and halides of alkali or alkaline earth metals, which are heat transfer substances and reaction media, catalyze oxidation reactions, and neutralize acid gases by forming stable salts. Although this method can be effective and safe Destroy explosive waste, but its processing efficiency is low, and there are certain safety hazards;
[0010] The supercritical water oxidation method is used to destroy expired and scrapped propellants or explosives. The reaction is carried out in a supercritical water oxidation reactor to achieve the purpose of destroying expired and scrapped propellants or explosives. The disadvantage of this method is that the process is complex and the equipment The investment is large, and the amount of disposal of waste explosives is limited, and its energy cannot be fully utilized;

Embodiment 1

[0055] A method for preparing fertilizer by hydrolyzing bulk propellants and / or explosives, comprising the following steps:

[0056] a. Prepare solution: prepare KOH with a mass concentration of 5-45% or NH with a mass concentration of 5-30% 4 OH or 5-40% NaOH, 1-10% potassium humate or 1-10% sodium humate; the concentration is 20-40% H 2 o 2 ;

[0057] b. Raw material pretreatment: crush bulk propellant and / or explosives to a fineness of 10-40 mesh, and use circulating water humidification method during crushing, so that the moisture content of bulk propellant and explosive is 4-6%; Add water 2-8 times the weight of the material to the pulverized raw material bulk propellant and / or explosives, and then add microorganisms for degradation. At least one of mildew, Penicillium parvum, Penicillium specificum, Penicillium fungus, Penicillium decumbens, Aspergillus niger, Aspergillus terreus, Rhizopus niger, Spot mold, Spot mold verruca, Spot mold black globus , adjust the pH va...

Embodiment 2

[0062] Its specific preparation method of the hydrolyzate fertilizer obtained by the hydrolysis of single-base propellants is as follows:

[0063] a. Prepare solution: prepare NaOH with a mass concentration of 10-30%, 1-10% potassium humate / sodium humate; concentration of 20-40% H 2 o 2 ;

[0064] b. Raw material pretreatment: crush the single-base propellant until its fineness is 10-40 mesh, and adopt circulating water humidification method during pulverization, so that the moisture content of the single-base propellant is 4-6%; Add water 2-8 times the weight of the material into the propellant, and then add microorganisms to degrade it. The microorganisms are: at least one of Trichoderma reesei, Aspergillus terreus, Rhizopus niger, and Spot mold. Adjust the pH value to 6-8. The degradation temperature is 40°C-50°C, and the degradation stops after 24-36 hours;

[0065] c. Reaction: Send the single-base propellant after microbial degradation into the reactor for reaction, c...

Embodiment 3

[0068] The specific preparation method of the fertilizer that the double-base propellants are hydrolyzed to remove the hydrolyzate that can be obtained is as follows:

[0069] a. Prepare solution: prepare NaOH with a mass concentration of 10-35%, potassium humate / sodium humate with a concentration of 1-10%; H with a concentration of 20-40% 2 o 2 ;

[0070] b. Raw material pretreatment: pulverize the double-base propellant until its fineness is 10-40 mesh, adopt circulating water humidification method during pulverization, make the water content of the double-base propellant be at 4-6%; Add water to the propellant according to the ratio of 2-8 times the weight of the material, adjust the pH value, and then add microorganisms to degrade. Adjust the pH value to 7-8, the degradation temperature is 30°C-40°C, and the degradation stops after 30-42h;

[0071] c. Reaction: Send the double-base propellant after microbial degradation into the reactor for reaction, control the tempera...

Abstract

The invention belongs to the field of processing methods of energy-containing materials, in particular to a fertilizer prepared by hydrolysis of bulk propellant powder and / or explosives and a preparation method of the fertilizer. The method disclosed by the invention comprises the following specific steps of: crushing the propellant powder and / or the explosives, then adding an alkaline solution and sodium / potassium humate, reacting in a reaction kettle, and supplementing P2O5, H3PO4, HCl, HNO3 or of K2SO4, Na2SO4, KNO3, (NH4)3PO4 or selenium salt according to the content of each element in the solution after the end of the reaction to get the fertilizer. The method disclosed by the invention has the beneficial effects that, by adopting the method, the propellant powder and / or the explosives can be processed for hydrolysis and then further manufactured into the fertilizer which can be utilized by humankind, so that the problem that the propellant powder and / or the explosives can cause harm to the humankind and a survival environment of the humankind can be solved, and the wastes can be turned into useful things and further become the fertilizer with economic value.

Description

technical field [0001] The invention belongs to the field of processing methods for energetic materials, and in particular relates to a fertilizer prepared by hydrolyzing bulk propellants and / or explosives, and also relates to a preparation method of the fertilizer. Background technique [0002] The vast majority of propellants or explosives are often used in the military field to complete combat purposes such as propulsion, bombing, and projectile, and are the energy sources for weapons such as personal defense, land, sea, air, and aerospace. Propellants or explosives have a certain service life, and the instability and unsafety of the propellant or explosives will increase sharply, and become expired propellants or explosives. At the same time, since most propellants or explosives are poisonous, discarded propellants or explosives are also a pollution source that is harmful to the environment. Compared with domestic and industrial waste, although the number of expired prop...
