Further, the explosion-proof container body 51 and the explosion-proof container lid 60 have a structure in which both ends are narrowed in a semicircular cross section, and the pressure is not concentrated in one direction.

  By making the chambers double in this way, the pressure at the time of explosion can be dispersed, the diameter of the outer heating chamber 11 is, for example, 700 mm to 800 mm, and the diameter of the inner explosion-proof container body 51 is, for example, 400 mm to The size can be suppressed to about 500 mm.

  The heating chamber 11 has a resistance against a sudden pressure rise, and when sealed with the heating chamber lid 20, the heating chamber 11 has a structure in which no gas leaks except for the tip.

It is used for burning the processing object 200 which is the processing object stored in the container.

  Ordinary explosives generally ignite spontaneously at a temperature of about 240 ° C. For this reason, when the heating chamber 11 is heated to a temperature of, for example, about 400 ° C. with a heater, the explosive of the target explosive housed in the explosion-proof container body 51 reaches this spontaneous ignition temperature in about 10 to 20 minutes. , Will spontaneously ignite.

  Note that the temperature of the heater 40 is not limited to the above example, and may be controlled to a higher temperature to increase the processing speed. Conversely, the temperature is higher than the spontaneous ignition temperature and lower than the heating temperature. The time from the start of processing to combustion may be secured sufficiently.

  Even in this case, the explosive power is not generated as in the case of explosion at normal temperature because of the combustion of the explosive. As a result, the pressure resistance of the explosion-proof container can be kept low.

  Further, the temperature in the heating chamber 11 is increased by the heater 40 thereafter, thereby detoxifying the solid matter remaining in the chamber. In this case, it is desirable to raise the temperature to about 550 ° C. by the heater 40.

Reference numeral 60 denotes an explosion-proof container lid that covers the opening of the explosion-proof container body 51, and is configured to be released in the direction of the explosion-proof container body 51 so that the impact of the explosion does not directly propagate to the heating chamber.

  Reference numeral 70 denotes a fixing formed so as to be in close contact with the back surface of the explosion-proof container main body 51 that is fixed to the mounting guide 27 so that the explosion-proof container main body 51 does not move even during rapid heating and combustion when the processing object 200 is processed. It is a plate and prevents the shock wave from the explosion-proof container lid 60 from affecting the heating chamber 11.

  Reference numeral 80 denotes a heating chamber lid moving rail for taking the explosion-proof container body 51 into and out of the heating chamber 11 in a state where the explosion-proof container body 51 is mounted on the mounting plate 25 of the heating chamber lid 20. Reference numerals 110 and 120 denote fixing legs for positioning and fixing the heating chamber 11.

  Reference numeral 200 denotes a processing object such as an explosive to be processed. Reference numeral 250 denotes a positioning jig for positioning the processing object 200 at a substantially central portion in the explosion-proof container main body 51.

  Since the positioning jigs 250 and 260 are used for positioning and holding explosives, when the explosives are combusted and evaporated, they are placed at extremely high pressure and high temperature. Therefore, the positioning jigs 250 and 260 are not limited to those composed of a strong material that can be used repeatedly. Even if the positioning jigs 250 and 260 are used only once, they may be crushed or burned together with explosives. Good. When used only once, it is desirable that it be made of wood, for example. By using wood, no toxic gas or the like is generated even during combustion, and the residue can be made harmless.

  558 is a shutoff valve for controlling whether or not the gas in the heating chamber 11 and the buffer tank 600 is discharged to a low pressure state, and 600 is the pressure of the heating gas (exhaust gas) discharged from the heating chamber gas outlet 12. 650 is a vacuum pump for reducing the pressure in the heating chamber 11 and the buffer tank 600 (vacuum).

  Reference numeral 610 denotes a flow rate control valve that controls whether or not the combustion air from the buffer tank 600 is shut off, and the flow rate that flows when the combustion air is not shut off to a specified amount. Reference numeral 700 denotes a high-temperature combustor, and reference numeral 750 denotes a heater disposed on the outer periphery of the high-temperature combustor 700. The high temperature combustor 700 heats the inside by a heater 750 and raises the temperature to a temperature at which harmful substances and the like are completely spread.

Since the high temperature combustor 700 is heated by the heater 750, harmful substances and the like are completely combusted.

  Combustion air from the high-temperature combustor 700 is sent to the exhaust gas treatment device 800 via the pipe 770, and dangerous substances (for example, arsenic and heavy metals) contained in the exhaust gas are separated and separated from the separated exhaust gas treatment device 800. The separated product (drainage) is sent to the wastewater treatment device 850 through the pipe 820, and separates and solidifies harmful substances such as heavy metals contained in the wastewater sent by the wastewater treatment device 850. The combustion air from the exhaust gas treatment device 800 is subjected to removal of residual substances by the activated carbon filter 805 and is discharged to the atmosphere via the exhaust blower 810.

  Next, the explosives treatment procedure of the present embodiment system will be described with reference to FIG. FIG. 3 is a flowchart for explaining the explosive treatment procedure of the system according to the present embodiment.

  First, in step S1, as shown on the right side of FIG. 1, the positioning jig 250 is housed in the explosion-proof container body 51, and the processing object 200 is placed thereon.

  Subsequently, in step S3, the explosion-proof container main body 51 containing the processing object 200 is installed by the positioning jig 260 positioned on the mounting plate 25 of the heating chamber lid 20, and the fixing plate 27 is fixed to the mounting guide 27 of the mounting plate 25. Fix with 70.

Next, in step S <b> 5, the fixing plate 70 is installed on the mounting guide 28 and fixed to the mounting plate 25 so that the opening of the explosion-proof container main body 51 fits in the explosion-proof container lid 60.
Then, in step S7, the heating chamber lid 20 on which the explosion-proof container main body 51 is placed is placed on the heating chamber lid moving rail 80 and conveyed to the heating chamber 11 position.

1, the heating chamber lid 20 is fastened by the heating chamber lid locking device 30 through the outer peripheral high temperature gasket 35 of the heating chamber, and the heating chamber 11 and the heating chamber lid 20 are fixed in a sealed state. To do.
As a result, the mounting of the explosive material on the blasting chamber assembly 1 is completed, and the preparation for processing the processing object is completed.

  Now that the explosives are ready to be treated, the explosive treatment sequence is started. This sequence may be advanced by sequential activation by an operator, or may be automatically performed by a sequence control unit that controls overall control (not shown). Alternatively, the power controller 500 shown in FIG. 2 may be responsible for overall control of the present embodiment in addition to the processing control described below.

  First, as shown in step S <b> 9, the flow control valve 550 is closed before blasting to prevent outside air from flowing into the heating chamber 11. At the same time, the flow control valve 610 is closed to prevent the gas in the heating chamber 11 and the buffer tank 600 from being inadvertently discharged to the outside.

  Next, in step S11, the shutoff valve 558 is opened and the vacuum pump 650 is activated to exhaust the air in the heating chamber 11 and the buffer tank 600 (upstream side). Thereafter, after reducing the pressure to a predetermined pressure, the flow control valve 550 is closed and the vacuum pump 650 is automatically stopped.

In step S13, the power controller 500 energizes the heater 40 to start heating the heating chamber 11, and controls the heating chamber 11 to be maintained at a temperature of about 400 ° C., for example, as described above. At the same time, the heater 750 disposed around the high temperature combustor 700 is energized to start heating the high temperature combustor 700.
In subsequent step S15, the combustion and evaporation of the processing object 200 are monitored. When the processing object 200 is burned and evaporated, for example, the temperature detected by the temperature sensor 510 rises, or a pressure change occurs in the heating chamber 11 and the buffer tank 600. When any or all of these are detected, the process proceeds from step S15 to step S17, the exhaust blower 810 is operated, the flow control valve 610 is opened, and exhaust at a predetermined flow rate is started.

  In step S <b> 19, the power controller 500 increases the set heating temperature of the heater 40 (for example, 550 ° C.) and detoxifies the remaining solid matter. At the same time, the combustion gas and evaporate are made harmless by high temperature combustion in the high temperature combustor 700 and further sent to the exhaust gas treatment device 800. Even in this case, since the air in the heating chamber 11 and the buffer tank 600 is exhausted by the vacuum pump 650 in advance, the amount of exhaust gas that needs to be processed can be minimized, and the configuration for exhaust gas treatment Can be made compact.

  In the exhaust gas treatment device 800, the harmful substances that have not been burned are further removed, and the combustion air from the exhaust gas treatment device 800 is subjected to removal of residual substances by the activated carbon filter 805, and safe exhaust gas is passed through the exhaust blower 810. Discharged into the atmosphere. At this time, it is desirable to control the flow rate control valve 550 after the pressure in the heating chamber is reduced to about atmospheric pressure so that outside air gradually flows into the heating chamber. Even in this case, since the exhaust blower 810 exhausts the gas in the heating chamber, the gas in the heating chamber is not discharged from the flow control valve 550 to the outside.

In subsequent step S21, it is monitored that the exhaust of the combustion gas and the evaporate in the heating chamber 11 is completed. For example, exhaust may be completed when a predetermined time has elapsed. When the exhaust of the evaporated material is completed, the process proceeds from step S21 to step S23, and the power controller 500 stops energization of the heater 40 (and the heater 750) to lower the temperature of the chamber.
At the same time, in step S25, the flow control valve 550 is fully opened to allow a large amount of outside air to flow into the heating chamber to lower the temperature in the heating chamber.

  In subsequent step S27, the temperature of the chamber is monitored to be lowered by the temperature detected by the temperature sensor 510. When the temperature in the chamber is lowered, for example, when the temperature falls to a level of 100 ° C., the process proceeds from step S27 to step S29, the heating chamber lid locking device 30 is removed, the heating chamber lid 20 is opened, and the explosion-proof container body 51 is placed. Move backwards.

In subsequent step S31, the residue (detoxified solid) in the heating chamber is taken out and discarded.
By repeating the above processing, it is possible to process the processing object 200 such as explosives that may discharge toxic gas and the like safely and reliably. For example, by preparing two sets or more of the explosion-proof container 51 or the heating chamber lid, the explosive material is previously incorporated in another explosion-proof container during the above-mentioned operation, and after the heated heating chamber lid is pulled out, By repeating the operation of attaching the heating chamber lid in which the processing object is incorporated into the heating chamber, the processing efficiency can be increased. For example, place one on the rail, remove the treated explosion-proof container (heating chamber lid), and move the new explosion-proof container (heating chamber lid) placed on the rail along the rail. What is necessary is just to set to a heating chamber.

  As described above, the entire chamber can be downsized and the entire system configuration including the exhaust gas treatment can be made compact, making it suitable for treating a small amount of dangerous explosives. As a result, it can be manufactured at low cost.

  Furthermore, the present invention is not limited to the case of treating only explosives, and even if poison gas bullets or contaminated soil is stored, it can be rendered harmless without contaminating the surroundings, and a wide range of applications can be achieved. Further, since the remaining material after the treatment remains as a residue in the heating chamber, it can be easily taken out and the treatment becomes easy.

  Furthermore, since the chamber is depressurized by the vacuum pump 650 before the explosives are processed, the overall gas flow rate can be reduced, the exhaust gas treatment device 800 can be downsized, and the gas flow rate is reduced, so that the energy used is reduced. be able to.

  Furthermore, there was little dirt and automation became easier. The fragments and solid residues after the gas is released after combustion (explosion) remain in the explosion-proof container without diffusing to the surroundings, and can be easily taken out and discarded for each explosion-proof container.

[Second Embodiment]

For example, a configuration may be adopted in which an explosion-proof container in the heating chamber is sealed and the processing object is accommodated therein. By adopting this structure, the pressure applied to the inner wall of the heating chamber can be reduced as compared with the first embodiment, and further cost reduction or weight reduction is realized.
