Embodiment 1

[0041] A method for preparing fertilizer by hydrolysis of explosives in an explosive device, comprising the steps of:

[0042] a. Prepare solution: prepare KOH with a mass concentration of 5-45% or NH with a mass concentration of 5-30% 4 OH or 5-30% NaOH, 1-10% potassium humate or 1-10% sodium humate; the concentration is 20-40% H 2 o 2 or sodium perborate or perborochromate;

[0043] b. Reaction: Put the explosive device containing explosives in the cage device, then put the cage device into the reaction tank, add alkali, potassium humate or sodium humate and water into the reaction tank, the above three substances The weight ratio is: 3-30: 2-20: 50-90; adding 20-40% H 2 o 2Or sodium perborate or perborochromate, then add catalyst, catalyst is at least one in Diwald alloy, Cd, Cd-Hg alkaloid, aluminum, zinc, Arndt alloy, Pd, Cu, the addition amount of catalyst accounts for 5-10% of the weight of the reaction material, in the reaction process, the material in the reactio...

Embodiment 2

[0047] The explosive contained in the explosive device is a nitro compound explosive, and the specific method of hydrolyzing it to make fertilizer is as follows:

[0048] a. Prepare solution: prepare NaOH, 1-10% potassium humate or 1-10% sodium humate with a mass concentration of 5-30%; concentration of 20-40% H 2 o 2 ;

[0049] b. Reaction: Put the explosive device containing nitro compound explosives in the cage device, then place the cage device in the reaction tank, add alkali, potassium humate or sodium humate and water into the reaction tank, and the above three The weight ratio of a substance is: 3-30: 2-20: 50-90; adding concentration is 20-40% H 2 o 2 Or sodium perborate or perborochromate, then add catalyst, catalyst is at least one in Diwald alloy, Cd, Cd-Hg alkaloid, aluminum, zinc, Arndt alloy, Pd, Cu, the addition amount of catalyst accounts for 5-10% of the weight of the reaction material, during the reaction process, spray or rotate the reaction cage on the...

Embodiment 3

[0052] The explosive contained in the explosive device is a mixed explosive of nitro compounds and nitramines, and the method for preparing fertilizer by hydrolysis is as follows:

[0053] a. Prepare solution: prepare NaOH, 1-10% potassium humate or 1-10% sodium humate with a concentration of 15-30%; concentration of 20-40% H 2 o 2 ;

[0054] b. Reaction: place the explosive device containing nitro compounds and nitramine mixed explosives in a cage device, then place the cage device in a reaction tank, add alkali, potassium humate or sodium humate and Water, the weight ratio of the above three substances is: 3-30: 2-20: 50-90; adding concentration is 20-40% H 2 o 2 Or sodium perborate or perborochromate, then add catalyst, catalyst is at least one in Diwald alloy, Cd, Cd-Hg alkaloid, aluminum, zinc, Arndt alloy, Pd, Cu, the addition amount of catalyst accounts for 5-10% of the weight of the reaction material, during the reaction process, spray or rotate the reaction tank o...

Abstract

The invention belongs to the field of preparing fertilizers by obtaining energetic materials in an explosive device and particularly relates to a fertilizer prepared by hydrolyzing explosives in the explosive device as well as a preparation technology and a preparation method for the fertilizer. The method comprises the following steps: the explosive device is put in a reaction cage, the reaction cage is put in a reaction tank, alkali, sodium humate / potassium humate and water are added for hydrolysis reaction, and at least one of P2O5, H3PO4, HCL and HNO3 or K2SO4, Na2SO4, KNO3 and (NH4)3PO4 or selenium salts is added after hydrolysis, so as to obtain the fertilizer. With the adoption of the method, the explosive device is put in the reaction cage, the reaction cage is put in the reaction tank, the alkali and the sodium humate / potassium humate are added for the hydrolysis reaction, the poisonous and harmful energetic materials are converted to be inorganic salts used for preparing the fertilizer, and then the fertilizer is prepared by the inorganic salts. The method has the characteristics that material taking and de-energizing can be realized safely from the explosive device, and the fertilizer capable of being utilized by human can be prepared by the energetic materials, thereby turning waste into wealth and creating great economic benefit.

Description

technical field [0001] The invention belongs to the field of making fertilizer from energetic materials in explosive devices, and in particular relates to a fertilizer obtained by hydrolysis of explosives in explosive devices, and also relates to a preparation process and method of the fertilizer. Background technique [0002] Separating waste explosives from old ammunition is the primary process for dealing with expired and scrapped explosives. This process is relatively dangerous and difficult. When separating, the existence of ignition devices and detonating devices, as well as occasional accidents The impact between metal and explosives can lead to accidents. Because of the close combination of explosives and projectiles and the change of the state of energetic materials, it is difficult to safely separate explosives from old ammunition. Currently, the commonly used method There are several types: [0003] 1. Separation of propellant from waste ammunition [0004] The ...
