Description

  The present invention is directed to a waste that is decomposed and reduced in volume without being burned by irradiating the waste thrown into a sealed container with minute air that has been magnetized or ionized through a magnetic field. It relates to a processing furnace.

Conventionally, incineration is performed for the treatment of general waste and industrial waste.
In this incineration process, harmful substances and fly ash are generated with combustion, and this harmful substance is scattered with the fly ash and contaminates nearby soil and the like.

In order to solve such a problem, a treatment method for suppressing generation of harmful substances by melting waste at a high temperature has been adopted.
However, even in such a melting process, a large amount of electric power or fossil fuel is required, which causes an increase in carbon dioxide emission.

  Furthermore, as a processing method for solving these problems of incineration and melting, a technique for irradiating a waste with a minute amount of air that has passed a magnetic field and decomposing the waste has been proposed (Patent Literature). 1).

In the above-mentioned patent documents, the magnet means forms a magnetic field on the air passage, whereby oxygen or the like in the heat treatment air is activated. It has been explained that waste is treated while suppressing the generation of harmful substances by performing oxidation reaction or carbonization treatment, but the waste is decomposed using such a minute amount of air that has passed through a magnetic field. It is not clear about the mechanism to do.
However, the operation of the present applicant has also been confirmed.

JP 2003-117534 A

  The applicant of the present application is that in the process of performing the waste treatment by the above-described waste treatment furnace, the waste treatment is uneven, incomplete treatment occurs, and the treatment efficiency is lower than expected. As a result of intensive studies to improve these, the present invention has been completed.

The present invention has been made in order to solve the above-mentioned problems, and the waste treatment furnace according to claim 1 is provided with a sealed container into which waste is charged and an upper part of the sealed container. An exhaust passage for exhausting the gas generated therein, an air supply passage provided in the sealed container, for feeding a minute amount of air into the airtight container, and an air supply passage provided between the air supply passage. A waste treatment furnace including a pair of magnets that form a transverse magnetic field, and a partition wall spaced apart from an inner wall surface is provided inside the sealed container, and a part of the air supply path is the It is formed by a conduit projecting inward from the inner wall surface of the sealed container, and the opening surface at the tip of the conduit is formed to be inclined with respect to the axis of the conduit. Is.
A waste treatment furnace according to claim 2 of the present invention is characterized in that the partition wall according to claim 1 is formed over the entire inner peripheral surface of the sealed container.
A waste treatment furnace according to claim 3 of the present invention is characterized in that a plurality of the partition walls according to claim 1 are provided at intervals in the surface direction of the sealed container.
The waste treatment furnace according to claim 4 of the present invention is characterized in that the partition wall according to any one of claims 1 to 3 has a plurality of communication holes penetrating the partition wall. To do.

  According to the waste treatment according to the first aspect of the present invention, a minute amount of air flowing into the air supply passage is magnetized or ionized when passing through a magnetic field formed by a pair of magnets in the air supply passage. Then, it is inferred that when the minute amount of air is irradiated to the waste filled in the sealed container, the waste is processed by decomposing them at the molecular level.

In addition, heat is generated with the decomposition treatment, and a combustion phenomenon occurs due to the reaction between oxygen and waste in the minute amount of air that flows into the sealed container due to this heat. By being sealed, the oxygen is consumed instantaneously, the inside of the sealed container becomes almost oxygen-free, and the above-described waste decomposition treatment is performed in this almost oxygen-free state.
Further, the temperature in the sealed container rises due to the heat generated by the decomposition process of the waste, so that the movement of the magnetized or ionized air is activated, and the above-described decomposition process is promoted.

Along with the generation of heat as described above, gas is generated along with the heat generation described above, and this gas rises in the sealed container and is externally connected through an exhaust passage provided at the upper part of the sealed container. Is exhausted.
Here, the inside of the sealed container is provided with a partition wall that is substantially parallel to the inner wall surface of the sealed container, so that these gaps serve as a flow path for the gas, and the gas is contained in the sealed container. It is led to the upper part and smoothly led to the exhaust path.

  By smoothly exhausting the gas in the hermetic container in this way, the minute air from the air supply passage is also smoothly flown, and as a result, the magnetized or ionized minute air necessary for the decomposition is removed. A supply amount is ensured, and a stable decomposition process is continuously performed.

  Further, the magnetized or ionized trace air used for the decomposition is sent into the sealed container through a conduit projecting from the inner wall surface of the sealed container toward the center, which constitutes a part of the air supply path. However, at the distal end portion of the conduit, the sealed container has a certain extent from the distal end of the conduit due to the difference in resistance of the tube wall and the deviation of the open position in the tube axial direction due to the inclined opening of the conduit. Flows in.

  Thereby, the minute air flowing into the sealed container is irradiated to the waste with a certain thickness, the decomposition region formed in the sealed container is expanded, and the decomposition efficiency and the decomposition speed are improved.

  In addition, these synergistic actions reduce the unevenness of waste processing, ensure a more uniform and more complete decomposition process, and improve the processing speed.

  According to a second aspect of the present invention, the partition wall is formed over the entire inner peripheral surface of the hermetic container, thereby ensuring a large flow area above the generated gas and allowing the generated gas to escape. Can be made good.

  In addition, as described in claim 3, by providing a plurality of the partition walls at intervals in the surface direction of the sealed container, the area of the flow path through which the generated gas passes above is reduced. Even in the case where the residue generated in the gap enters the gap, the residue or the like in the gap is likely to fall into the sealed container at the portion where the partition wall is not provided. Clogging is suppressed, and a flow path for escape of the generated gas is secured.

  Furthermore, as described in claim 4, by forming a large number of communication holes penetrating the partition wall in the partition wall, it is possible to more surely drop residues and the like that have entered the gap between the partition wall and the inner wall of the sealed container. As a result, the above-described escape of the generated gas can be secured.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a waste treatment furnace according to the present embodiment. The waste treatment furnace 1 is arranged in a circumferential direction at a closed container 2 into which waste is charged and a lower peripheral edge of the closed container 2. The air supply path 3 is formed at six locations spaced apart from each other, and the exhaust path 4 is provided above the sealed container 2 and discharges the generated gas in the sealed container 2 to the outside. .

More specifically, in the present embodiment, the sealed container 2 is formed in a cylindrical shape, and the upper and lower portions are hermetically closed by a disk, and the upper surface thereof, as shown in FIG. An opening / closing lid 5 is provided so as to occupy substantially half of the upper surface.
A sealing material such as packing is interposed between the open / close lid 5 and the sealed container 2 so that no gap is formed between the open / close lid 5 and the closed container 2 in a closed state. It can be blocked.

Further, a part of the exhaust path 4 is formed in the upper part of the sealed container 2 and in the vicinity of the part where the opening / closing lid 5 is formed, and a continuous communication pipe 6 is attached in the sealed container 2. The water tank 7 in which water is stored is attached to the communication pipe 6 in a communication state.
In this water tank 7, water is stored from the lower surface to a predetermined height, and the upper half of the inside is a space portion g in which the upper end portion of the communication pipe 6 is opened, and this space portion g is the exhaust gas. A part of the road 4 is formed.

Further, an exhaust pipe 8 that constitutes a part of the exhaust passage 4 is provided on the upper surface of the water tank 7 so as to communicate the space g and the outside air.
Therefore, the generated gas in the sealed container 2 is discharged from the communication pipe 6 through the space g of the water tank 7 to the outside air from the exhaust pipe 8, but while passing through the space g of the water tank 7, The water is cooled and condensed by being brought into contact with the water, and is captured by the water in the water tank 7.

  On the other hand, the opening / closing lid 5 is fixed to a pivot 10 rotatably attached to the upper surface of the hermetic container 2 via a pair of brackets 9, and one end of the pivot 10 is attached to one end of the pivot 10. An operation rod 11 that rotates is provided orthogonally. When the pivot 10 is rotated by the operation rod 11, the opening / closing lid 5 rotates up and down around the pivot 5 as a rotation center. Thus, the waste input port 2a formed on the upper surface of the sealed container 2 is opened and closed.

  A lock lever 12 is swingably mounted on the upper surface of the open / close lid 5, and the lock lever 12 is engaged with a locking piece 13 fixed to the upper surface of the sealed container 2 in a wedge shape. As a result, the open / close lid 5 is brought into pressure contact with the upper portion of the sealed container 2 to hermetically seal the waste input port 2a.

A cylindrical partition wall 14 is installed on the inner side of the closed container 2 with a space S between the inner wall surface and the closed container 2 by a plurality of connecting plates 15 disposed therebetween. It is integrated.
The upper end portion and the lower end portion of the partition wall 14 are spaced apart from the upper wall and the lower wall of the sealed container 2 by a predetermined distance, respectively. To communicate with each other.

  As shown in FIG. 3, each of the air supply passages 3 includes a conduit 16 protruding through the side wall of the hermetic container 2 and projecting inside, and an end of the conduit 16 at the outside of the hermetic container 2. A connected joint 17, a valve 18 that is connected to the joint 17 and adjusts the amount of air flowing through the air supply path 3, and a casing that is attached to the valve 18 and communicates with the outside air. 19.

Each of the conduits 16 is made of metal in the present embodiment, and is installed so as to penetrate the side wall of the sealed container 2 and toward the center thereof.
And the front-end | tip part (end part of the center part side of the airtight container 2) of each said conduit | pipe 16 is made into the opening surface 16a inclined with respect to the axis line, as shown in FIG.

  Further, as shown in FIGS. 4 and 5, a through hole 19 a constituting a part of the air supply path 3 is formed in the center portion of the casing 19, and in the middle of its length direction. The magnet mounting holes 19b orthogonal to the through holes 19a are provided on both sides of the through holes 19a.

  These magnet mounting holes 19b have an outer end portion opened to the outer surface of the casing 19, an inner end portion opened to the through hole 19a, and a small diameter between the through hole 19a. The predetermined step portion H is formed.

  In each of these magnet mounting holes 19b, a permanent magnet 20 is mounted, and the outer end of each magnet mounting hole 19b is closed by a plug 21.

  The magnets mounted in the magnet mounting holes 19b are mounted so that different magnetic poles face each other, that is, attract each other, and are formed at the inner end of the magnet mounting hole 19b. By being engaged with H, it is positioned in the casing 19 by the respective attractive forces, and most of its surface is exposed in the through hole 19a at the inner end of the magnet mounting hole 19b. ing.

  Further, in the present embodiment, the distal end portion of the conduit 16 is positioned through the lower portion of the partition wall 14 as shown in FIG.

  In the present embodiment, as shown in FIGS. 4 and 6, the partition wall 14 is formed with a large number of communication holes 22 penetrating the partition wall 14, and is formed by a distance S from the sealed container 2. The gap formed is communicated with the inside of the partition wall 14.

  On the other hand, residue discharge ports (not shown) for taking out the residue generated in the closed container 2 are formed at two places on the lower side wall of the closed container 2. As shown in FIG. 2, it is opened and closed by a lid 23 attached to the outer surface of the hermetic container 2 so as to be openable and closable and engageable at a closed position, and is hermetically closed at the closed position.

    The operation of the waste treatment furnace 1 according to the present embodiment configured as described above will be described. First, the operating rod 11 is operated to rotate the opening / closing lid 5 upward, thereby allowing the upper portion of the sealed container 2 to be moved. After the waste inlet 2a is opened and waste is densely charged inside the partition wall 14, the open / close lid 5 is closed to make the sealed container 2 airtight.

  Next, by operating each valve 18, the amount of minute air flowing from each air supply path 3 is adjusted so as to be the amount of processing air necessary for processing according to the type and amount of input waste. To do.

  Here, at the time of initial operation, since the inside of the sealed container 2 is at room temperature, there is no movement of gas in the sealed container 2 and it does not operate as it is, but the inside of the sealed container 2 is heated to a predetermined temperature. As a result, the gas in the airtight container 2 starts to rise between the partition wall 14 and the airtight container 2 or from a gap between untreated waste, and this gas is exhausted through the exhaust passage 4. Ascending airflow is formed in the sealed container 2.

When an upward air flow is generated in the closed container 2 in this manner, the pressure at the bottom of the closed container 2 is reduced, so that a small amount of air flows from each air supply path 3 due to atmospheric pressure.
The minute air is magnetized by being passed through a magnetic field formed by a permanent magnet 20 attached to the casing 19 while passing through the casing 19 constituting a part of the air supply path 3. Alternatively, it is ionized and flows into the sealed container 2.

The magnetized or ionized trace air is irradiated to the waste in the sealed container 2 at a certain speed, and the inside of the sealed container 2 is heated so that the waste and the magnetized or By the collision with the ionized trace air, the decomposition process of the waste at the molecular level is started.
This is presumed to be a phenomenon caused by the destruction of the intermolecular bonds of the waste due to the magnetic force or ions of the trace air flowing in.

  Due to the heat of decomposition accompanying the start of such decomposition treatment, the temperature in the sealed container 2 further rises to the combustion temperature of the waste, but most of the waste in the sealed container 2 is untreated. In addition, since the inside of the sealed container 2 is filled with waste and the amount of oxygen inside is extremely small, oxygen and inflow in the sealed container 2 are reached when the combustion temperature of the waste is reached as described above. Oxygen in the minute amount of air to be consumed is instantaneously consumed and combustion is stopped, and thereafter, the temperature rises only by the decomposition heat described above.

  As long as there is unprocessed waste in the sealed container 2, this heat of decomposition is continuously generated by the collision of this waste with magnetized or ionized trace air, and is thus described in a state without combustion. By continuously supplying the heat necessary for the decomposition, the movement of the magnetized or ionized trace air is activated and the decomposition process of the waste is continuously performed.

  In addition, since the volume of the decomposed waste is reduced to about several tenths, as the processing continues, the upper untreated waste sequentially moves downward to be decomposed and is therefore charged. Disposal processing of waste is continued.

On the other hand, gas is generated in the sealed container 2 with the above-described decomposition process, and this gas secures an exhaust passage between the partition wall 14 and the sealed container 2 together with the gas flow in the sealed container 2 described above. Therefore, it moves smoothly upward in the sealed container 2 and is discharged to the outside air through the exhaust passage 4.
As a result, the smooth exhaust of the generated gas is ensured, and along with this, the inflow of a minute amount of air from the air supply path 3 is also secured stably. From this point of view, the waste decomposition process described above is also performed. Continuity is ensured.

  Further, the generated gas moves not only between the partition wall 14 and the sealed container 2 but also moves upward through the gap between the untreated waste above, but while passing through the waste gap, Since the untreated waste is preheated, the decomposition process in the lower part becomes smooth.

  Further, in the present embodiment, since a large number of communication holes 22 penetrating in the surface direction are formed in the partition wall 14, the degree of freedom of movement of the generated gas in the sealed container 2 is increased, and the exhaust efficiency of the generated gas is increased. By improving, the efficiency of the above-described decomposition is improved, and the unevenness of the decomposition is suppressed and a uniform decomposition process is performed.

  Further, since the facing area between the partition wall 14 and the airtight container 2 is reduced due to the presence of the communication hole 22, it is possible to suppress clogging of wastes between them, and even when clogged, the separation is performed. As a result, the smoothness of the escape of the generated gas can be ensured.

The distal end portion of the conduit 16 for feeding a minute amount of magnetized or ionized air into the sealed container 2 is an opening surface 16a inclined with respect to its axis.
By using such an opening surface 16a, the restraint release position by the conduit 16 with respect to the minute amount of air flowing into the sealed container 2 from the opening surface 16a differs in the axial direction. As a result, the minute amount of air flowing from the tip of the conduit 16 However, as shown by an arrow (A) in FIG. 4, the flow spreads forward.

  Accordingly, the irradiation area of the magnetized or ionized trace air with respect to the waste is expanded, so that a wide range of decomposition processes are performed and a uniform decomposition process is performed.

7 and 8 show a second embodiment of the present invention.
In this embodiment, instead of the cylindrical partition wall 14 in the above-described embodiment, a plurality of flat partition walls 24 are provided at intervals in the circumferential direction.

  By adopting such a configuration, a gap D continuous vertically between the partition walls 24 while securing a rising path of the generated gas with a circumferential interval between the partition walls 24 and the inner wall of the sealed container 2. The degree of freedom of movement of the generated gas can be increased, and clogging of waste in the gap D can be prevented.

  Also in the present embodiment, by forming the plurality of communication holes 25 in each partition wall 24, it is possible to improve the freedom of movement of the generated gas and to prevent the clogging of the waste.
