Problems solved by technology

[0008] However, after a long time of abandonment, the residual chemical substance remaining in the cartridge case denatures and becomes a polymer. As a result, an insoluble film is formed on the surface. The problem of promoting the hydrolysis reaction
In addition, in order to solve the above problems, it is conceivable to cut the film and the main body of the residue finely in advance, but there is a disadvantage that the cutting operation is required to be precise, and at the same time it brings trouble to the process, so that the entire processing time becomes longer and the efficiency is low.

Embodiment 1

[0033] figure 1 To represent the process flow diagram of embodiment 1 of the present invention. figure 1 Among them, 1 is a chemical bomb, 2 is a dismantling machine installed in the dismantling room for dismantling and disposing of the chemical bomb 1, 3 is a reaction tank for the solution solution after the residue (solid residue) is dissolved by hydrolysis and oxidation treatment, and 4 is A treatment liquid storage tank for storing the above-mentioned treated liquid.

[0034] First, fix the chemical bomb 1, use a dismantling machine to drill a hole in its case 1a, then insert a nozzle into it, cut off the explosive part mechanically, separate the explosive part and the case, pass through the nozzle, and supply the above-mentioned solution to the solvent supply pipe L1. Organic solvents S such as MIBK are circulated through the solvent circulation pipe L2 using the pump 5, thereby washing and dissolving the residue remaining in the cartridge case. Washing and dissolving w...

Embodiment 2

[0041] Another process embodiment of the present invention is described below. figure 2 It is a process flow diagram representing Embodiment 2 of the present invention. In this embodiment, the description of the parts that overlap with the above-mentioned embodiment 1 is omitted, and the different parts are mainly explained.

[0042] First, in the same manner as in Example 1, the above-mentioned organic solvent S such as MIBK, etc. are supplied to the solvent supply line L1 through the nozzle inserted after the cartridge case 1a of the chemical bomb 1 is opened, and the pump 5 is used to circulate them through the solvent circulation line L2. , thereby washing and dissolving the residue left in the cartridge case by the treatment (1st wash and treatment).

[0043] Then, after dissolving and removing a certain amount of residue through the first washing and dissolving, the supply and circulation of the organic solvent S is stopped, and the circulating liquid, that is, the res...

Abstract

A neutralization treatment method for solid residue in waste chemical weapon, meaning a method for decontaminating and neutralizing solid remaining in a bullet shell (1a) of a chemical bullet (1), includes the steps of washing and dissolving the solid residue using an organic solvent to obtain a solid residue solution, and neutralizing said solid residue solution with an alkaline solution A and an oxidant O. Such a neutralization treatment method for solid residue in waste chemical weapon is capable of detoxifying entire sediment effectively in a short period of time by absolutely and promptly dissolving all the sediment (heal) of chemical weapons and by promoting hydrolysis.

Description

technical field [0001] The invention relates to a method for neutralizing and treating the solid residue adhering to and remaining in discarded chemical weapon shell casings to make it into a harmless substance. Background technique [0002] It has been known that chemical weapons (chemical bombs) using highly toxic chemical substances such as mustard gas and Lewis gas have recently been clarified that a considerable amount of unidentified This kind of chemical weapon that has been disposed of and directly abandoned, and as a major social problem that threatens the human body and life, has aroused widespread concern in society, and people hope to complete its safe disposal as soon as possible so that it is harmless to human beings . [0003] In the past, chemical bombs were usually dealt with in the following way. [0004] (1) First fix the chemical bomb recovered from the ground, use a dismantling machine to open a hole in the above-mentioned shell case, and then insert a...
