[0003]

However, the above conventional methods for treating propellants, propellants, etc. have the following problems. (1) From the viewpoint of environmental protection, the method of dumping propellants and propellants into the sea is prohibited, and all are about to be transferred to land. (2) Regarding the method of incineration in an open state at a treatment plant that uses open land on land, etc.
Flight of propellants, explosion sounds, and scattered objects occur, which poses a risk of physical and human damage. (3) The method of preventing the propellant / propellant from flying, explosive sound, and generation of scattered matter by a wire netting basket or a protective wall is effective when treating a large amount of propellant / propellant. It is reduced, it is not possible to expect the efficiency of work and expansion of processing capacity, and there is a problem that part of the material flies and remains unburned during processing. (4) In the method of directly burning the propellant / propellant in the combustion furnace, there is a risk of causing wear of the high temperature furnace at the time of combustion.
Various characteristics of explosives to be incinerated to prevent this (ease of explosion,

In addition, in order to eliminate the risk of explosion, negative pressure is applied to the inside of the combustion furnace and the furnace path, the amount of incineration is controlled so that a large amount of lumps are not formed at one time, and it is very important to control the temperature inside the furnace to outside the dangerous area. Requires labor and equipment. Furthermore,
In the unlikely event of an electrical or mechanical failure, there is a risk that it will explode or burn beyond the control limits, and there is a risk of equipment and human damage. (5) In the treatment method described in Japanese Patent Publication No. A-B, propellant, oil and solid particulate matter are uniformly mixed and then molded into a predetermined shape,
Since this molded product is burned, a mixing process, a molding process, and a combustion process are required, which requires a large amount of equipment, labor, and time,
It has problems of poor workability and poor processing efficiency. (6) The method of chemically modifying propellant, propellant, etc. to eliminate the explosiveness is still at the stage of technological development, and it is currently possible to process a large amount of propellant, propellant, etc. in a short time. There is a problem that processing efficiency is low because it cannot be performed.

It is an object of the present invention to provide a method for treating a propellant / propellant, which has extremely high workability and treatment efficiency capable of performing the combustion treatment of

[0005]

After the cP incineration additive is attached, absorbed or dissolved by spraying, dipping, etc., the propellant / propellant is burned for processing. With this configuration, when the propellant / propellant is ignited due to the incineration additive adhering, absorbing or melting, the fire spreads all at once, leading to full combustion of the propellant / propellant from the start of combustion. You can In addition, the incineration additive permeates the inside of the propellant / propellant, and the composition of the propellant / propellant changes, making it possible to greatly reduce the combustion temperature and burning rate of the propellant / propellant. . Furthermore, the incineration additive adhering to the surface of the propellant / propellant absorbs the energy of the combustion flame from the explosive particles during the adjacent combustion of the propellant / propellant, and suppresses the increase in the combustion speed and combustion temperature. can do.

Further, as the length / outer diameter becomes larger than 20, it tends to be difficult to handle and lack safety, which is not preferable. Further, the propellant / propellant having the above-mentioned shape has an outer diameter of 4 to 25 mm, preferably 6 to 12 m.
Those with m are desirable. If the outer diameter is smaller than 4 mm, flying of propellant / propellant, explosive sound, and the generation of scattered materials are almost eliminated, and it takes a lot of time for companding / cutting.

As a result, the propellant / propellant having the incineration additive attached and absorbed or dissolved in the incineration additive is spread on the iron plate or the like, or is stacked and then burned. At the time of incineration, it is not necessary that the place to be burned is closed or separated by a protective wall, a wire netting basket or the like, and the propellant / propellant can be burned in an open environment. With this configuration, solid propellant / propellant such as single-hole tubular or porous tubular or rod-shaped, or solid propellant / propellant processed and manufactured by cutting or companding into these shapes is burned. If this is done, combustion will immediately spread to the whole due to the incineration additive adhering to, absorbed in, or dissolved in the propellant / propellant, thus preventing partial combustion starting or local progress of combustion. You can As a result, it is possible to prevent abnormal combustion such as flight of propellant / propellant and generation of explosion sound.
