Description

  The present invention relates to an organic waste treatment apparatus that performs heat treatment with oxidation or carbonization on organic waste housed in a furnace, and an exhaust gas purification apparatus that purifies exhaust gas generated by the heat treatment of organic waste housed in the furnace. It is about.

  In general, organic waste produced by human beings through various production and consumption activities is subjected to heat treatment with oxidation or carbonization in the process until final disposal.

  By the way, in recent years, generation of harmful substances such as hydrocarbons and dioxins accompanying the heat treatment as described above has become a big problem.

  Therefore, a heat treatment furnace as described in Patent Document 1 has been proposed from the viewpoint of suppressing generation of harmful substances such as hydrocarbons and dioxins accompanying heat treatment. Such a heat treatment furnace described in Patent Document 1 includes an air inlet provided with magnetic means. The waste is heat-treated in an external atmosphere (heat treatment air) magnetically treated by the magnetic means.

  On the other hand, devices such as those described in Patent Document 2 and Patent Document 3 have been proposed from the viewpoint of purifying exhaust gas containing harmful substances such as hydrocarbons and dioxins generated by heat treatment. In the devices described in Patent Document 2 and Patent Document 3, a secondary combustion chamber that is made into a high-temperature atmosphere by a gas or liquid fuel burner or a dielectric heating element is separately provided in addition to a furnace for heat-treating organic waste. Is. The exhaust gas generated in the furnace is allowed to pass through a secondary combustion chamber having a high temperature atmosphere, thereby decomposing harmful substances such as dioxins contained in the exhaust gas.

  However, if the high temperature atmosphere is maintained in the secondary combustion chamber, there is a problem that the amount of fuel and electric power consumed increases. There is also a problem that the apparatus becomes large in terms of heat resistance and the like.

  As a method for treating the exhaust gas, methods such as those described in Patent Document 4, Patent Document 5, and Patent Document 6 have been proposed in addition to those having such a secondary combustion chamber. Patent Documents 4 to 6 describe that exhaust gas is washed by spraying a treatment liquid against exhaust gas in a pipe that guides exhaust gas generated in a furnace.

  However, there is a problem that it is difficult to spray the treatment liquid on all of the exhaust gas, and it is difficult to sufficiently clean the exhaust gas.

  Further, Patent Document 7 describes a device that opens a pipe connected to a furnace into water in a water tank and guides exhaust gas discharged from the furnace into water. In the apparatus described in Patent Document 7, harmful substances contained in the exhaust gas are removed with water, so that only the purified gas is diffused into the air.

  However, the exhaust gas generated in the furnace changes the momentum discharged depending on the combustion state in the furnace, and is not always discharged at a substantially constant momentum.

  In particular, in the carbonization furnace and the charcoal manufacturing apparatus described in Patent Document 8 and Patent Document 9, it is general that the flameless state is set in the carbonization process. Therefore, unlike the case where organic waste is incinerated in an incinerator, the pressure in the furnace is not so high and the exhaust gas discharged has little momentum.

  Therefore, when heat treatment involving carbonization or oxidation is performed in a furnace in a flameless state, there has been a problem that it is difficult to stably discharge the exhaust gas discharged from the furnace into the water in the water tank.

  It is also possible to adjust the amount of air sucked into the furnace by adjusting the amount of exhaust gas discharged. Therefore, it is desirable to be able to adjust the exhaust gas emission from the viewpoint of realizing effective heat treatment by adjusting the progress of carbonization or oxidation.

  Thus, for example, a suction fan may be provided on the exhaust gas flow path from the furnace to the water tank, and the exhaust gas generated in the furnace may be sucked by the suction fan (see Patent Document 7).

  However, since tar or the like contained in the exhaust gas adheres to the suction fan, there is a problem that the durability of the suction fan is significantly reduced.

  It is also conceivable that a suction fan is provided at the exhaust port from the water tank, and the exhaust gas generated in the furnace is sucked by the suction fan. However, in such a case, the suction fan is required to have a very large negative pressure generation capability, which is not realistic.

  When removing harmful substances contained in the exhaust gas discharged from the furnace with water, it is desirable to increase the contact area between the exhaust gas and water in order to remove more harmful substances.

  Therefore, by separating and dividing the exhaust gas with a plurality of thin tubes provided in the duct and then dissipating it into the treatment liquid, the contact area between the exhaust gas and the treatment liquid becomes small bubbles when discharging the exhaust gas into the treatment liquid. It is conceivable to increase (see Patent Document 4).

  However, there is a problem that it is difficult to realize bubbles of a target size because there is a limit to the size of the thin tube that can be manufactured.

  In addition, as described in Patent Document 4, when the opening positions in the processing liquid of the plurality of thin tubes are different from the liquid level of the processing liquid, the opening closest to the liquid level of the processing liquid due to the differential pressure Exhaust gas is discharged only from Therefore, in the apparatus described in Patent Document 4, it is impossible to discharge exhaust gas into the processing liquid as small bubbles.

  JP 2003-117534 A   Japanese Patent Laid-Open No. 7-225015   JP-A-5-315070   JP-A-8-57254   JP 2001-79347 A   Utility model registration No. 3092884   JP-A-57-190628   Japanese Utility Model Publication No.59-28541   Japanese Patent Laid-Open No. 58-1780

  Here, the present invention has been made in the background as described above, and the problem to be solved is that the amount of exhaust gas generated in the furnace can be adjusted and the exhaust gas can be efficiently used. It is an object of the present invention to provide an organic waste treatment apparatus having a novel structure that can be purified in an effective manner.

  Another object of the present invention is to provide an exhaust gas treatment apparatus having a novel structure capable of efficiently purifying exhaust gas generated in a furnace.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible. Further, aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification, or an invention idea that can be grasped by those skilled in the art from those descriptions. It should be understood that it is recognized on the basis of.

  The present invention relating to an organic waste treatment apparatus comprises a magnetic treatment means, and air magnetically treated by the magnetic treatment means is introduced into the furnace, and the organic waste contained in the furnace is subjected to the magnetic treatment air. In the organic waste treatment apparatus that performs heat treatment accompanied by oxidation or carbonization, (a) a purification treatment liquid for purifying exhaust gas generated when the organic waste is heat treated with the magnetic treatment air in the furnace is stored. (B) one end of which is connected to the furnace, while the other end is opened in the purification treatment liquid stored in the liquid tank, and the exhaust gas generated in the furnace is An exhaust gas introduction path to be introduced into the purification treatment liquid of the liquid tank; (c) a pump for pumping up the purification treatment liquid stored in the liquid tank; and (d) one end connected to the discharge side of the pump. While the other end is The purification treatment liquid pumped up by the pump is discharged toward the liquid level of the purification treatment liquid in the exhaust gas introduction passage and guided into the exhaust gas introduction passage. It is characterized by comprising a treatment liquid discharge flow path for entraining the exhaust gas in the purification treatment liquid and releasing it from the exhaust gas introduction path.

  In such an organic waste treatment apparatus having a structure according to the present invention, the organic waste housed in the furnace is subjected to heat treatment accompanied by oxidation or carbonization with air magnetically treated by the magnetic treatment means. Therefore, the organic waste is efficiently and gently heat-treated with a small amount of magnetically treated air.

  As a result, the organic waste does not raise a large flame, and heat treatment with slow oxidation or carbonization proceeds over time not only on the surface of the organic waste but also mainly in a wide area inside. . As a result, it is possible to perform heat treatment while suppressing the generation of harmful substances such as dioxins in a state close to complete combustion.

  In addition, the theoretical basis for the generation and release suppression effects of dioxins, etc. exerted by air magnetically processed by magnetic processing means has not yet been clarified, and the theoretical basis for these should be clarified. Although not the object of the present invention, a magnetic field is formed by the magnetic processing means, so that oxygen in the air is activated, and as a result, the amount of air introduced into the furnace is small. Even so, it is conceivable that a heat treatment involving mild oxidation or carbonization is suitably maintained.

  Further, in the present invention, since the exhaust gas generated in the furnace is introduced into the purification treatment liquid stored in the liquid tank by the exhaust gas introduction path, the exhaust gas and the purification treatment liquid are brought into contact with each other, It becomes possible to remove harmful substances contained in the exhaust gas with the purification treatment liquid.

  Accordingly, in the present invention, a treatment liquid discharge passage connected to the discharge side of a pump that pumps the purification treatment liquid stored in the liquid tank is opened in the exhaust gas introduction passage. Then, the purification treatment liquid pumped up by the pump is discharged toward the surface of the purification treatment liquid in the exhaust gas introduction path. As a result, the exhaust gas guided through the exhaust gas introduction path is caught in the purification treatment liquid and released from the exhaust gas introduction path. As a result, the exhaust gas flows toward the other end side in the exhaust gas introduction path.

  In this way, a flow of exhaust gas toward the other end side is generated in the exhaust gas introduction path, so that a negative pressure is generated in the exhaust gas introduction path. As a result, the exhaust gas generated in the furnace is sucked into the exhaust gas introduction path.

  Therefore, in the organic waste treatment apparatus according to the present invention, by appropriately adjusting the discharge amount per unit time of the purification treatment liquid into the exhaust gas introduction path, the exhaust gas flow in the exhaust gas introduction path, that is, The magnitude of the negative pressure generated in the exhaust gas introduction path can be adjusted. This makes it possible to adjust the amount of exhaust gas generated in the furnace that is sucked into the exhaust gas introduction path. As a result, the amount of air introduced into the furnace can be adjusted, and an effective heat treatment for organic waste in the furnace can be advantageously realized.

  That is, in the organic waste treatment apparatus according to the present invention, the speed and degree of heat treatment, and even the furnace temperature, can be adjusted by adjusting the exhaust gas emission amount. . In other words, the operating state of the furnace can be controlled by adjusting the exhaust gas emission amount. This cannot be realized by conventional free exhaust or exhaust by a fan. Conventionally, in an oxidation furnace or carbonization furnace that heat-treats with a small amount of supply and exhaust, the operation state of the furnace is controlled by adjusting the opening of the valve on the intake side. However, it was difficult to control the operating state accurately due to the influence of the outside wind. However, according to the present invention, even in such a furnace, the state of the furnace can be controlled very easily and with high accuracy.

  Further, in the present invention, the purification treatment liquid discharged from the treatment liquid discharge passage into the exhaust gas introduction passage collides with the liquid level of the purification treatment liquid stored in the liquid tank, thereby introducing the inside of the exhaust gas introduction passage. The exhaust gas that has been generated is entrained in the purification treatment liquid. As a result, the exhaust gas can be discharged into the purification treatment liquid stored in the liquid tank as microbubbles. As a result, it is possible to ensure a large contact area between the exhaust gas and the purification treatment liquid and to advantageously remove harmful substances contained in the exhaust gas with the purification treatment liquid.

  In this embodiment, the other end of the exhaust gas introduction path is always in the purification treatment liquid when the exhaust gas is being processed. Thereby, the exhaust gas always passes through the purification treatment liquid.

  A first aspect of the present invention relating to an exhaust gas purification device is an exhaust gas purification device for purifying exhaust gas generated in a furnace, wherein: (a) a liquid tank storing a purification treatment liquid for purifying the exhaust gas; and (b ) One end side is connected to the furnace, while the other end side is opened in the purification treatment liquid stored in the liquid tank, and at least a plurality of the other end sides opened in the purification treatment liquid are provided. An exhaust gas introduction path for introducing the exhaust gas generated in the furnace into the purification treatment liquid, (c) a pump for pumping up the purification treatment liquid stored in the liquid tank, and (d) one end side of the pump The other end side is connected to the inside of the plurality of other end sides of the exhaust gas introduction path, and the purification treatment liquid pumped up by the pump is introduced into the exhaust gas. A treatment liquid jetting passage for discharging respective inside each other ends in, that it includes, characterized.

The exhaust gas guided to the path is caught in the purification treatment liquid and is discharged from the exhaust gas introduction path.

  Thereby, the flow of the exhaust gas toward the other end side is generated in the exhaust gas introduction path. As a result, a negative pressure is generated in the exhaust gas introduction path, and the exhaust gas generated in the furnace is sucked into the exhaust gas introduction path.

  Therefore, in this aspect, the amount of exhaust gas generated in the furnace is sucked into the exhaust gas introduction passage by appropriately adjusting the amount of the purification treatment liquid discharged per unit time from the processing liquid discharge passage, That is, the amount of exhaust gas discharged from the furnace can be adjusted.

  As a result, for example, even when the exhaust gas generated in the furnace has no momentum, it is possible to advantageously realize the suction of the exhaust gas into the exhaust gas introduction path and efficiently discharge the exhaust gas from the furnace. It becomes. As a result, the exhaust gas can be efficiently purified.

  Further, in this embodiment, since the amount of exhaust gas discharged can be adjusted, the speed and degree of heat treatment in the furnace, and eventually the furnace temperature can also be adjusted.

Conventionally, in an oxidation furnace or carbonization furnace that performs heat treatment with a small amount of supply and exhaust, the operation state of the furnace has been controlled by adjusting the opening of the valve on the intake side. It was difficult because the amount of exhaust gas to be produced was very small, and it was difficult to accurately control the operating state due to the influence of external winds. However, by using the exhaust gas purifying apparatus of this aspect, even in such a furnace, the state of the furnace can be controlled very easily and with high accuracy.

  Therefore, in this aspect, since the exhaust gas introduction path is provided with a plurality of at least the other end side that opens into the purification treatment liquid, the exhaust gas introduction path is secured while ensuring the flow area in the entire exhaust gas introduction path. It is possible to reduce the flow path area on the other end side.

  And in this aspect, since the other end side of the processing liquid discharge flow path is opened inside each other end side of the exhaust gas introduction path whose flow path area is thus reduced, each of the exhaust gas introduction paths It is possible to enlarge a region through which the purification processing liquid discharged from the processing liquid discharge channel passes inside the other end side.

  Thereby, even if the capacity | capacitance of a pump is small, it becomes possible to speed up the flow of exhaust gas inside each other end side of the exhaust gas introduction path. As a result, an effective negative pressure can be generated inside each other end side of the exhaust gas introduction path.

  Therefore, in this aspect, it is possible to advantageously secure the amount of exhaust gas generated in the furnace that is sucked into the exhaust gas introduction path, and it is possible to purify the exhaust gas more efficiently.

  In this embodiment, the other ends of the exhaust gas introduction path are all in the purification treatment liquid when the exhaust gas is being purified. As a result, the exhaust gas always passes through the purification treatment liquid.

It becomes possible to do.

As a result, even when the capacity of the pump is small, it is possible to generate an effective negative pressure in the exhaust gas introduction passage, and advantageously secure the amount of exhaust gas generated in the furnace being sucked into the exhaust gas introduction passage. It becomes possible to do.

It becomes possible to release. Thereby, exhaust gas can be discharged efficiently.

  Further, the exhaust gas can be brought into contact with the purification treatment liquid more efficiently.

As a result, it is possible to enlarge a region where the discharged purification treatment liquid passes through the inside of the other end, and as a result, it is possible to generate an effective negative pressure in the exhaust gas introduction path. Therefore, the exhaust gas generated in the furnace can be actively sucked into the exhaust gas introduction path, and thereby the exhaust gas can be efficiently purified. Moreover, it becomes possible to control the operating state of the furnace by adjusting the exhaust gas emission amount.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  First, an embodiment of the present invention relating to an organic waste treatment apparatus will be described with reference to FIGS. 1 and 2. The organic waste treatment apparatus 10 heat-treats the burning material 14 as organic waste housed in a carbonization furnace 12 as a furnace, and purifies the exhaust gas generated by the heat treatment by the exhaust gas purification apparatus 16. After that, it is designed to be released into the atmosphere. In the present embodiment, the soot burning material 14 is composed of rice husk, sawdust, or the like.

  More specifically, the carbonization furnace 12 has a structure in which an opening 20 formed in a furnace body 18 for storing a soot burning material is covered with a lid body 22 so as to be openable and closable. It is made into a shape.

  The furnace body 18 is formed by welding or the like of a plurality of plate members having a rectangular flat plate shape having a substantially constant thickness dimension. Thereby, the furnace body 18 has a rectangular box structure in which an opening 20 is formed in a part of the upper wall 24 and opens upward. In addition, the board | plate material which forms the furnace main body 18 is formed with heat resistant materials, such as a ferrous metal.

  Further, an insertion hole 30 penetrating in a circular cross section is formed on the lower side of the front side wall 28 of the furnace body 18, and a metal cylinder 32 is inserted and fixed to the insertion hole 30. . The fixing of the cylindrical body 32 to the insertion hole 30 is not particularly limited as long as it is a method capable of ensuring airtightness in a fixed state. For example, press fitting or welding may be used. Also good.

  In this manner, an air introduction pipe 34 formed of a nonmagnetic material such as a rubber elastic body or a synthetic resin material is fixed to the cylinder 32 fixed to the furnace body 18. The air introduction pipe 34 is fixed to the cylinder 32 by, for example, fitting the air introduction pipe 34 into the cylinder 32 and bonding the outer peripheral surface of the air introduction pipe 34 and the inner peripheral surface of the cylinder 32 or the like. This is advantageously realized.

  A pair of permanent magnets 36 and 36 as magnetic processing means are attached to the outer peripheral surface of the air introduction pipe 34 fixed to the cylindrical body 32. Each permanent magnet 36 has a cylindrical shape and has magnetic poles different from each other at both bottom surface portions. As a material for forming the permanent magnet 36, for example, a ferrite magnet having excellent cost performance can be preferably used. In addition, various hard magnetic materials such as an alnico magnet and a rare earth magnet can be used as magnetic materials. It can be adopted as appropriate in consideration of characteristics and cost.

  Each permanent magnet 36 is formed of a nonmagnetic material such as a synthetic resin material and is accommodated in a casing 38 having a bottomed cylindrical shape as a whole. In this way, the permanent magnet 36 accommodated in the casing 38 has one magnetic pole surface superimposed on the bottom surface of the casing 38 and the other magnetic pole surface exposed to the outside through the opening of the casing 38. It is fixed to the casing 38 by adhesion or the like.

  The casing 38 is bonded to the outer peripheral surface of the intermediate portion in the axial direction of the air introduction tube 34, so that the magnetic pole surface exposed from the casing 38 in the permanent magnet 36 is superimposed on the outer peripheral surface of the air introduction tube 34. In this state, the permanent magnet 36 is fixed to the outer peripheral surface of the air introduction pipe 34.

  As a result, a magnetic field is formed on the air passage of the air introduction pipe 34. As a result, magnetic treatment is applied to the air circulated through the air passage. Here, the polarity and position of the magnetic poles of the pair of permanent magnets 36, 36 are not particularly limited, but preferably only one of the N pole and the S pole is in close proximity to or close to the air introduction pipe 34. It will be set to be superimposed. Incidentally, in the present embodiment, the pair of permanent magnets 36 and 36 are opposed to each other on the same magnetic pole surface with the air introduction tube 34 interposed therebetween.

  Further, an insertion hole 42 is formed in the rear side wall 40 of the furnace body 18 at the upper end side, and a metal discharge pipe 44 is inserted and fixed to the insertion hole 42. The fixing of the discharge pipe 44 to the insertion hole 42 is not particularly limited as long as it is a method that can ensure airtightness in a fixed state. For example, press fitting or welding may be used. good.

  Furthermore, a rooster 46 is provided in the furnace body 18 above the bottom wall and above the insertion hole 30 through which the cylindrical body 32 is inserted and fixed. The soot burning material 14 is placed on the rooster 46.

  On the other hand, the lid body 22 is formed of a plate material having a rectangular flat plate shape having a substantially constant thickness dimension. In addition, the board | plate material which comprises the cover body 22 is formed with heat resistant materials, such as a ferrous metal.

  The lid 22 is disposed at a position that covers the opening 20 formed in the upper wall 24 of the furnace body 18 and is connected to the upper wall 24 of the furnace body 18 by hinges 48 and 48. As a result, the opening 20 formed in the furnace body 18 is opened or closed.

  Further, the lid 22 is provided with a lock arm 50 supported so as to be rotatable along the upper surface thereof. The lock arm 50 is locked to a hooking portion 52 provided on the front side wall 28 of the furnace body 18, so that the lid 22 is maintained in a state where the opening 20 is closed.

  In the carbonization furnace 12 having such a structure, the top layer of the soot burning material 14 accumulated in the rooster 46 is ignited by a seed fire thrown from the opening 20, and then the lid 22 is closed to open the opening 20. It is supposed to block. Then, the soot burning material 14 is burnt from the upper layer to the lower layer, and when the soot burning material 14 reaches the lowermost layer, the air introduction tube 34 is closed by closing the air introduction tube 34 or the like. By cutting off the air, charcoal is produced.

  At that time, the soot burning is performed by causing the magnetically treated air supplied from the air introduction pipe 34 to reach the part in the soot burning material 14 where the soot is burning. When the soot is completed, the exhaust gas generated by soot passes through the upper part of the soot 14 that has already been sooted, and is discharged to the outside through the discharge pipe 44. Ashing of the ignited soot burning material 14 is prevented.

  Further, when the soot burning of the soot burning material 14 is completed and the soot burning material 14 is carbonized, the soot burning does not proceed any further in the charcoal, and the magnetically treated air sent from below and fresh soot burning. Due to the interaction with the material 14 and the heat of the bottom of the charcoal immediately after the carbonization of the soot, it moves to the lower layer. Then, the magnetically treated air that is continuously sent is used for soot burning in the lower layer portion of the soot burning material 14, so that soot burning is continued without being interrupted to the lowest layer.

  The exhaust gas generated by the above-described soot is discharged from the discharge pipe 44 to the outside, and after being purified by the exhaust gas purification device 16, is discharged into the atmosphere. The exhaust gas purification device 16 includes a water tank 56 as a liquid tank in which water 54 as a purification treatment liquid is stored. The water tank 56 is formed by welding or the like of a plurality of plate members having a rectangular flat plate shape having a substantially constant thickness dimension. Thereby, the water tank 56 is made into the hollow box structure as a whole. In addition, the board | plate material which forms the water tank 56 is formed with metal materials, such as iron.

  In addition, an insertion hole 60 is formed in the upper wall 58 of the water tank 56, and a metal introduction pipe 62 is inserted into and fixed to the insertion hole 60. The introduction pipe 62 is fixed to the insertion hole 60 as long as it is a method that can ensure airtightness in a fixed state. For example, press-fitting or welding may be used. Also good.

  Therefore, in the present embodiment, the introduction pipe 62 has a cylindrical shape, extends substantially in the vertical direction, and is inserted and fixed in the insertion hole 60 in a state of projecting to both the outside and the inside of the water tank 56. . In particular, in the present embodiment, a portion of the introduction pipe 62 that protrudes inside the water tank 56 is positioned in the water 54 that has a protruding end stored in the water tank 56. In other words, in the present embodiment, one end portion of the introduction pipe 62 (the end portion in the water tank 56) is opened in the water 54 stored in the water tank 56.

  An introduction pipe 64 made of a synthetic resin material is connected to the other end of the introduction pipe 62 (the end located outside the water tank 56). In the present embodiment, the introduction pipe 64 is fitted into the introduction pipe 62 and the inner peripheral surface of the introduction pipe 64 and the outer peripheral surface of the introduction pipe 62 are bonded together, so that the introduction pipe 64 and the introduction pipe 62 are fixed. ing.

  The introduction pipe 64 is integrally provided with a connecting tube portion 66 having a cylindrical shape extending outward in a direction perpendicular to the axis at an axially intermediate portion thereof. The connecting tube portion 66 and the discharge pipe 44 provided in the furnace body 18 are connected by a connecting pipe 68 made of synthetic resin. In the present embodiment, the discharge pipe 44 is fitted into one end of the connection pipe 68, while the connection cylinder portion 66 is fitted into the other end of the connection pipe 68. Then, the connection pipe 68 and the discharge pipe 44 are fixed by adhering the inner peripheral surface of the connection pipe 68 and the outer peripheral surface of the discharge pipe 44, and the outer peripheral surface of the connection pipe 68 and the connection cylinder portion 66. By connecting the surfaces, the connection pipe 68 and the connection cylinder portion 66 are fixed.

  Thereby, the carbonization furnace 12 and the water tank 56 are communicated with each other by the discharge pipe 44, the connection pipe 68, the introduction pipe 64, and the introduction pipe 62. As a result, the exhaust gas generated in the carbonization furnace 12 is led into the water 54 stored in the water tank 56 through the discharge pipe 44, the connection pipe 68, the introduction pipe 64 and the introduction pipe 62. ing. As is clear from this, in the present embodiment, the exhaust pipe 44, the connection pipe 68, the introduction pipe 64, and the introduction pipe 62 constitute the exhaust gas introduction path 70.

  Further, a through hole 72 is formed in the side wall of the water tank 56 at the lower end side, and a metal connecting pipe 74 is inserted into and fixed to the through hole 72. Note that the fixing of the connecting pipe 74 to the through hole 72 is not particularly limited as long as it is a method capable of ensuring airtightness in a fixed state. For example, press fitting may be used, or welding may be performed. It may be.

  The connecting pipe 74 and the suction side pipe of the pump 76 are connected to each other by a synthetic resin suction side connecting pipe 78. Thereby, the water 54 in the water tank 56 is sucked into the pump 76. This pump 76 is configured by a conventionally known magnet drive type centrifugal pump, and rotates the impeller in the pump chamber by magnetic force so as to send out the water 54 stored in the water tank 56 from the suction side to the discharge side. It has become.

  Further, a discharge side connection pipe 80 made of a synthetic resin material is connected to the discharge side pipe of the pump 76. The discharge side connection pipe 80 is connected to a metal discharge pipe 84 that is inserted into and fixed to an opening hole 82 formed on the other axial end side of the introduction pipe 64.

  Here, fixing of the discharge pipe 84 to the opening hole 82 is advantageously realized by bonding the outer peripheral surface of the discharge pipe 84 and the inner peripheral surface of the opening hole 82. In this embodiment, the discharge tube 84 and the introduction tube 82 are positioned on the same central axis in a state where the discharge tube 84 is fixed to the opening hole 82 in this way. That is, the discharge pipe 84 is also arranged so as to extend in a substantially vertical direction. In the present embodiment, the discharge pipe 84 has a cylindrical shape with a smaller diameter than the introduction pipe 62.

  As is clear from these, in the present embodiment, the discharge pipe 84 positioned on the other end side (exhaust gas introduction path 70 side) of the processing liquid discharge flow path 86 described later has an exhaust gas in the axial projection. It opens at the center of the cross section of the introduction pipe 62 located on the other end side (water tank 56 side) of the introduction path 70, and the opening direction is a substantially vertical direction.

  The discharge pipe 84 and the discharge side connection pipe 80 are connected by fitting the discharge pipe 84 into the discharge side connection pipe 80 and bonding the inner peripheral surface of the discharge side connection pipe 80 and the outer peripheral surface of the discharge pipe 84. This is advantageously realized.

  As described above, the discharge side connection pipe 80 and the discharge pipe 84 are connected, so that the water 54 pumped up by the pump 76 is discharged from the discharge side pipe, the discharge side connection pipe 80 and the discharge pipe 84 in the pump 76. And is discharged into the introduction pipe 64. Therefore, in this embodiment, since the discharge pipe 84, the introduction pipe 64, and the introduction pipe 62 all extend in the vertical direction, the water 54 discharged into the introduction pipe 64 is stored in the water tank 56. The water 54 is discharged toward the water surface. As is clear from this, in the present embodiment, the discharge side connection pipe 80 and the discharge pipe 84 constitute a processing liquid discharge flow path 86.

  Furthermore, in addition to the insertion hole 60, a through hole 88 is formed in the upper wall 58 of the water tank 56, and a discharge pipe 90 is inserted into and fixed to the through hole 88. The fixing of the discharge pipe 90 to the through-hole 88 is not particularly limited as long as it is a method that can ensure airtightness. For example, press-fitting or welding may be used. As described above, the discharge pipe 90 is provided on the upper wall 58, so that the water surface of the water 54 stored in the water tank 56 is exposed to the external space through the discharge pipe 90.

  In the organic waste treatment apparatus 10 having such a structure, the soot burning material accommodated in the carbonization furnace 12 by the air magnetically treated by passing through the magnetic field formed by the pair of permanent magnets 36, 36. Since 14 is burned, the burning material 14 is burned efficiently and gently with a small amount of magnetically treated air.

  Thereby, it is possible to slowly burn the soot burning material 14 over time without burning it up. As a result, it is possible to advantageously realize soot carbonization of the soot burning material 14 while suppressing the generation of harmful substances.

  Further, in the organic waste treatment apparatus 10 described above, after the exhaust gas generated in the carbonization furnace 12 is introduced into the water 54 stored in the water tank 56 through the exhaust gas introduction path 70, the discharge pipe 90 is connected to the organic waste treatment apparatus 10. Since the gas is discharged into the atmosphere by passing through, the harmful substances contained in the exhaust gas can be removed by bringing the exhaust gas into contact with the water 54.

  In particular, in the organic waste treatment apparatus 10 described above, the water 54 pumped up by the pump 76 is discharged toward the water surface of the water 54 stored in the water tank 56 in the exhaust gas introduction path 70. Since the discharged water 54 collides with the water surface, the exhaust gas guided into the exhaust gas introduction path 70 is entrained in the water 54, so that the exhaust gas is turned into microbubbles and the water tank 56. It becomes possible to discharge into the water 54 stored in the tank. As a result, a large contact area between the exhaust gas and the water 54 can be secured, and harmful substances contained in the exhaust gas can be advantageously removed by the water 54.

  Further, in the above-described organic waste treatment apparatus 10, the water 54 pumped up by the pump 76 is discharged toward the water surface of the water 54 stored in the water tank 56 in the exhaust gas introduction path 70, and the exhaust gas introduction path. The exhaust gas that has been introduced into the inside 70 is entrained in the water 54 so that it is discharged from the exhaust gas introduction path 70. Thereby, in the exhaust gas introduction path 70, the flow of the exhaust gas toward the water tank 56 side is generated. As a result, an effective negative pressure is generated in the exhaust gas introduction path 70, and the exhaust gas generated in the carbonization furnace 12 is sucked into the exhaust gas introduction path 70.

  Therefore, in the organic waste treatment apparatus 10 described above, the flow of the exhaust gas in the exhaust gas introduction path 70, that is, the exhaust gas introduction, is adjusted by adjusting the discharge amount of the water 54 per unit time into the exhaust gas introduction path 70. It becomes possible to adjust the magnitude of the negative pressure generated in the passage 70. This makes it possible to adjust the amount of exhaust gas generated in the carbonization furnace 12 being sucked into the exhaust gas introduction path 70. As a result, it is possible to advantageously realize soot burning on the soot burning material 14 by adjusting the amount of magnetically treated air introduced into the carbonization furnace 12 through the air introduction pipe 34. That is, in the organic waste treatment apparatus 10 described above, the operating state of the carbonization furnace 12 can be controlled.

  Next, a first embodiment of the present invention relating to an exhaust gas purification device will be described based on FIGS. 3 and 4. In the following description, members and parts having the same structure as the members and parts used in the organic waste treatment apparatus (10) described above were used in the above description in the figure. Detailed description thereof will be omitted by giving the same reference numerals as the reference numerals.

  The exhaust gas purification device 92 of the present embodiment has an exhaust gas introduction path 94 and a treatment liquid discharge flow channel 96, as compared with the exhaust gas purification device (16) employed in the organic waste treatment apparatus (10) described above. The structure is different.

  More specifically, in this embodiment, four discharge pipes 44 are provided in the rear side wall 40 of the furnace body 18. Accordingly, four introduction pipes 62 are provided on the upper wall 58 of the water tank 56, and an introduction pipe 64 is attached to each introduction pipe 62. The fixing of each discharge pipe 44 to the furnace body 18 and the fixing of each introduction pipe 62 to the water tank 56 are advantageously realized by the method described above. Although not necessarily clear on the drawing, each introduction pipe 62 has a cylindrical shape, and its lower end surface (the open end surface on the underwater side) is positioned at the same height from the bottom surface of the water tank 56. .

  Then, the connecting tube portion 66 provided in each introduction pipe 64 and each discharge pipe 44 are connected to each other by a connection pipe 68. It should be noted that the fixing of each connecting tube portion 66 and each connecting pipe 68 and the fixing of each discharge pipe 44 and each connecting pipe 68 are advantageously realized by the method described above.

  Thereby, the exhaust gas generated in the carbonization furnace 12 as the heat treatment furnace passes through each discharge pipe 44, and thereafter, the connection pipe 68 connected to the discharge pipe 44, the introduction pipe 64 connected to the connection pipe 68, and the introduction pipe After passing through the introduction pipe 62 connected to 64, it is discharged into the water 54 stored in the water tank 56. As is clear from this, in the present embodiment, four exhaust gas discharge passages 98 constituted by the discharge pipe 44, the connection pipe 68, the introduction pipe 64 and the introduction pipe 62 are provided. In this embodiment, the exhaust gas introduction path 94 is constituted by these four exhaust gas discharge paths 98. That is, the exhaust gas introduction path 94 of this embodiment has four start ends (one end side) and four end ends (the other end side).

  In this embodiment, each connection pipe 68 is provided with an exhaust gas flow rate adjusting valve 100 as an introduction path opening / closing means.

  Furthermore, in this embodiment, a pump side connection pipe 102, a branch connection pipe 104, and an introduction path side connection pipe 106 are provided instead of the discharge side connection pipe (80). In the present embodiment, these connection pipes 102, 104, and 106 are all formed of a synthetic resin material.

  More specifically, one end side of the pump side connection pipe 102 is connected to the discharge side pipe of the pump 76, and the other end side is connected to the inlet side opening cylinder portion 108 in the branch connection pipe 104. In the present embodiment, the connection of the pump side connection pipe 102 to the inlet side opening cylinder part 108 is performed by fitting the inlet side opening cylinder part 108 into the pump side connection pipe 102. Then, the outer peripheral surface of the inlet side opening cylinder part 108 and the inner peripheral surface of the pump side connection pipe 102 are bonded together, so that the inlet side opening cylinder part 108 and the pump side connection pipe 102 are fixed.

  This branching connection pipe 104 includes four outlet side opening cylinder parts 110 in addition to the inlet side opening cylinder part 108, and the water 54 that has entered from the inlet side opening cylinder part 108 is supplied to the four outlet side opening cylinder parts 108. It works to send out from 110. Then, one end side of the introduction path side connection pipe 106 is connected to each of the four outlet side opening cylinder portions 110 provided in the branch pipe 104. In the present embodiment, the connection of the introduction path side connection pipe 106 to each exit side opening cylinder portion 110 in the branch connection pipe 104 is performed by fitting the exit side opening cylinder portion 110 into the introduction path side connection pipe 106. ing. Then, the outer peripheral surface of the outlet side opening cylinder part 110 and the inner peripheral surface of the introduction path side connection pipe 106 are bonded together, so that the outlet side opening cylinder part 110 and the introduction path side connection pipe 106 are fixed.

  In addition, the introduction path side connection pipe 106 whose one end side is connected to the outlet opening cylindrical portion 110 in this way is connected to a discharge pipe 84 that is fixedly provided to each introduction pipe 64 at the other end side. In the present embodiment, the connection between the introduction path side connection pipe 106 and the discharge pipe 84 is performed by fitting the discharge pipe 84 into the introduction path side connection pipe 106. The discharge pipe 84 and the introduction path side connection pipe 106 are fixed by bonding the outer peripheral face of the discharge pipe 84 and the inner circumference surface of the introduction path side connection pipe 106.

  Thereby, in this embodiment, after the water 54 sucked up by the pump 76 is sent to the branch connection pipe 104 through the pump side connection pipe 102, each of the four introduction path side connection pipes 106 receives each introduction pipe. 64 is discharged.

  Therefore, in this embodiment, each introduction path side connecting pipe 106 is provided with a discharge regulating valve 112 as a discharge regulating means.

  In the present embodiment, a through hole 114 is formed in the side wall of the water tank 54, and a metal drain pipe 116 is inserted into and fixed to the through hole 114. The fixing of the drain pipe 116 to the through hole 114 is not particularly limited as long as it is a method capable of ensuring airtightness in a fixed state. For example, press fitting may be used, or welding may be performed. It may be. A synthetic resin cap 118 is detachably attached to the outer end of the drain pipe 116, and the opening of the outer end of the drain pipe 116 is closed by attaching the cap 118. It is like that.

  Furthermore, in the present embodiment, the filter member 120 is provided on the bottom wall side of the introduction pipe 62 in the water 54 stored in the water tank 56. The filter member 120 is appropriately changed according to the harmful substance to be removed, and various conventionally known filters can be employed. Although not necessarily obvious on the drawings, the filter member 120 is attached to the side wall of the water tank 56 with screws or the like.

  In the exhaust gas purifying device 92 having such a structure, the water 54 pumped up by the pump 76 is introduced into the introduction pipe because the introduction path side connection pipe 106 is connected to the discharge pipe 84 fixed to the introduction pipe 64. 64, the exhaust gas guided to the exhaust gas introduction path 94 (each exhaust gas discharge path 98) is caught in the water 54, and the exhaust gas introduction path 94 (each exhaust gas discharge path 98). Will be released. Thereby, in the exhaust gas introduction path 94 (each exhaust gas discharge path 98), the flow of the exhaust gas toward the water surface side is generated. As a result, an effective negative pressure is generated in the exhaust gas introduction path 94 (each exhaust gas discharge path 98), and the exhaust gas generated in the carbonization furnace 12 is sucked into the exhaust gas introduction path 94 (each exhaust gas discharge path 98). Come.

  Therefore, in the exhaust gas purifying apparatus 92 of the present embodiment, the exhaust gas generated in the carbonization furnace 12 is adjusted to the exhaust gas introduction path 94 (each exhaust gas discharge path) by appropriately adjusting the amount of water 54 discharged per unit time. 98) It is possible to adjust the amount sucked into the inside, that is, the amount of exhaust gas discharged from the carbonization furnace 12. As a result, the exhaust gas can be efficiently discharged from the carbonization furnace 12, and as a result, the exhaust gas can be efficiently purified.

  Therefore, in the exhaust gas purifying apparatus 92 of the present embodiment, the exhaust gas introduction path 94 is constituted by the four exhaust gas discharge paths 98, so that the water tank 56 is secured while ensuring the flow path area in the entire exhaust gas introduction path 94. It is possible to reduce the flow area to the side. This makes it possible to increase the ratio of the area through which the water discharged in each introduction pipe 64 passes to the flow path area, and to generate an effective negative pressure in each introduction pipe 64.

  Therefore, in the exhaust gas purifying apparatus 92 of the present embodiment, it becomes possible to advantageously ensure the amount of exhaust gas generated in the carbonization furnace 12 being sucked into the exhaust gas introduction passages 94 (each exhaust gas discharge passage 98). Can be more efficiently purified.

  Further, in the exhaust gas purifying device 92 of the present embodiment, the exhaust gas flow rate adjusting valve 100 is provided in each connection pipe 68. Therefore, by operating each exhaust gas flow rate adjusting valve 100 appropriately, each exhaust gas discharge path 98 is provided. It is possible to adjust the amount of exhaust gas flowing through the water and the amount of exhaust gas released into the water 54.

  Further, in the exhaust gas purifying device 92 of the present embodiment, since the discharge adjustment valve 112 is provided in each introduction path side connection pipe 106, the discharged water 54 is obtained by appropriately operating each discharge adjustment valve 112. It is possible to adjust the amount. As a result, the amount of exhaust gas sucked into the exhaust gas introduction path 94 (each exhaust gas discharge path 98) can be adjusted.

  In the exhaust gas purifying device 92 of the present embodiment, the introduction pipe 62, the introduction pipe 64, and the discharge pipe 84 are arranged so as to extend in the vertical direction on the same central axis, and the vertical direction from the discharge pipe 84. Since the water 54 is discharged downward, gravity acts on the discharged water 54 in the discharge direction. This makes it possible to increase the speed at which the discharged water 54 collides with the water surface. As a result, even when the water 54 is discharged into each of the four introduction pipes 64 with one pump 76 as in the exhaust gas purification apparatus 92 of the present embodiment, an effective negative is introduced into each introduction pipe 64. It is possible to generate pressure, and it is possible to advantageously secure the amount of exhaust gas sucked into the exhaust gas introduction passages 94 (each exhaust gas discharge passage 98).

  Further, in the exhaust gas purifying apparatus 92 of the present embodiment, the discharge pipe 84 is opened at the center of the cross section of the introduction pipe 62 in the axial projection, and thus exhaust gas is released from the entire circumference of the opening of the introduction pipe 62. It becomes possible to do. As a result, exhaust gas can be discharged efficiently.

  In particular, in the exhaust gas purifying device 92 of this embodiment, since the introduction pipe 62 is cylindrical, the exhaust gas introduction path 70 opens into the water 54 with a circular cross section. Thereby, exhaust gas can be easily released from the entire circumference of the opening of the introduction pipe 62. As a result, the exhaust gas can be efficiently released.

  In the exhaust gas purifying apparatus 92 of the present embodiment, since the drain pipe 116 is provided, the cap 118 that closes the outer opening of the drain pipe 116 is removed, and the water 54 stored in the water tank 56 is drained. By discharging from 116, it is possible to adjust the height position of the water surface from the opening end face of the introduction pipe 62. As a result, the amount of exhaust gas discharged from the exhaust gas introduction path 70 can be adjusted. As is apparent from this, in this embodiment, the cap 118 and the drain pipe 116 constitute the introduction path opening position adjusting means.

  Further, in the exhaust gas purifying apparatus 92 of the present embodiment, the water 54 stored in the water tank 56 is pumped by the pump 76, thereby generating a flow toward the connecting pipe 74 with respect to the water 54 stored in the water tank 56. It is possible to squeeze. Thereby, it is possible to advantageously avoid the problem that the exhaust gas discharged into the water 54 from the introduction pipe 62 returns to the inside of the introduction pipe 62 again. That is, the flow of the water 54 toward the connection pipe 74 allows the exhaust gas bubbles to float on the water surface outside the introduction pipe 62, thereby causing the exhaust gas bubbles to float on the water surface inside the introduction pipe 62. Therefore, it is possible to avoid the problem that the exhaust gas returns to the introduction pipe 62 again. As a result, emission of exhaust gas from the exhaust gas introduction path 70 can be advantageously realized. As is clear from this, in this embodiment, the treatment liquid flow means is constituted by the pump 76.

An opening is made at the center of the cross section of the guide tube 130 located on the other end side (water tank 124 side) of the path 140, and the opening direction is a substantially vertical direction.

  The discharge pipe 154 and the discharge side connection pipe 150 are connected by fitting the discharge pipe 154 into the discharge side connection pipe 150 and bonding the inner peripheral surface of the discharge side connection pipe 150 and the outer peripheral surface of the discharge pipe 154. This is advantageously realized.

  As described above, the discharge side connection pipe 150 and the discharge pipe 154 are connected, so that the water 132 pumped up by the water storage tank pump 146 is discharged from the water storage tank pump 146. 150 and the discharge pipe 154 are discharged into the guide pipe 134. Therefore, in this embodiment, since the discharge pipe 154, the guide pipe 134, and the guide pipe 130 all extend in the vertical direction, the water 132 discharged into the guide pipe 134 is stored in the water storage tank 124. The discharged water 132 is discharged toward the water surface. As is clear from this, in the present embodiment, the liquid discharge flow path 156 is configured by the discharge side connection pipe 150 and the discharge pipe 154.

  Furthermore, in addition to the insertion hole 128, a through hole 158 is formed in the upper wall 126 of the water storage tank 124, and a discharge pipe 160 is inserted into and fixed to the through hole 158.

  Also in the exhaust gas purifying device 122 having such a structure, the water 54 pumped up by the pump 76 is discharged into each introduction pipe 64. Therefore, the exhaust gas purifying device of the first embodiment ( 92) can be obtained.

  Therefore, in the exhaust gas purifying apparatus 122 of the present embodiment, the exhaust gas purified by the water 54 stored in the water tank 56 passes through the exhaust gas guiding path 140 and is separately provided in addition to the water tank 56. Since the gas is discharged into the water 132 stored in the tank 124, the exhaust gas purified by the water 54 stored in the water tank 56 is further purified by the water 132 stored in the water tank 124. As a result, the exhaust gas can be purified more effectively.

  In particular, in the exhaust gas purification device 122 of the present embodiment, the water 132 stored in the water storage tank 124 is pumped up by the water storage tank pump 146 and discharged into the exhaust gas guiding path 140. The exhaust gas guided into the exhaust gas guiding path 140 is caught in the water 132 and discharged from the exhaust gas guiding path 140. Thereby, the flow of the exhaust gas toward the water surface side of the water 132 stored in the water storage tank 124 in the exhaust gas guiding path 140 is generated. As a result, an effective negative pressure is generated in the exhaust gas guiding path 140, and the exhaust gas purified by the water 54 stored in the water tank 56 is sucked into the exhaust gas guiding path 140.

  Therefore, in the exhaust gas purifying apparatus 122 of this embodiment, it is advantageously realized that the exhaust gas purified by the water 54 stored in the water tank 56 is further purified by the water 132 stored in the water storage tank 124. It becomes possible.

It flows to the tube 144 side. Thereby, it is possible to avoid the problem that the exhaust gas discharged from the exhaust gas guiding path 140 returns to the exhaust gas guiding path 140 again. That is, the flow of the water 132 toward the connecting pipe 144 can cause the exhaust gas bubbles to float on the water surface outside the guide pipe 130. As a result, it is possible to avoid the problem that the exhaust gas bubbles float on the water surface inside the guide tube 130 and the exhaust gas returns to the guide tube 130 again. As a result, it is possible to advantageously realize emission of exhaust gas from the exhaust gas guiding path 140. As is clear from this, in this embodiment, the liquid flow means is constituted by the water tank pump 146.

It can be removed. As a result, the exhaust gas purification process can be performed more effectively.

  Furthermore, in the exhaust gas purifying device 122 of the present embodiment, since the water 132 is discharged downward in the vertical direction, gravity acts on the discharge direction of the water 132. This makes it possible to increase the speed at which the discharged water 132 collides with the water surface. As a result, an effective negative pressure is generated in the exhaust gas guiding path 140, and the amount of exhaust gas sucked into the exhaust gas guiding path 140 can be advantageously ensured.

  Further, in the exhaust gas purifying apparatus 122 of the present embodiment, the guide pipe 130 fixed to the water storage tank 124 and the discharge pipe 154 fixed to the guide pipe 134 are positioned on the same central axis, and the discharge pipe Since 154 has a cylindrical shape smaller in diameter than the guide tube 130, the discharge tube 154 is opened at the center of the cross section of the guide tube 130 in the axial projection. Thereby, exhaust gas can be discharged from the entire circumference of the opening of the guide tube 130. As a result, exhaust gas can be discharged efficiently.

  In particular, in the exhaust gas purifying apparatus 122 of the present embodiment, since the guide pipe 130 has a cylindrical shape, the exhaust gas guide path 140 has a circular cross section and opens into the water 132. Thereby, exhaust gas can be easily released from the entire circumference of the opening of the guide tube 130. As a result, the exhaust gas can be efficiently released.
