Description

  The present invention is a combustion part provided in the central part of the processing furnace main body, combustible waste is burned at a high temperature, treated, and heated in an environment where the temperature gradually decreases around the combustion part, and the waste The present invention relates to a waste treatment apparatus that separates volatile components such as moisture contained in. In particular, in addition to combustible waste such as paper waste, fallen leaves and plants with slightly dried moisture, waste such as household waste, garbage and plastic generated at small-scale establishments, etc. The present invention relates to an apparatus that efficiently incinerates waste without causing pollution such as foul odors and harmful gases.

  Then, the combustible waste is burned at a high temperature in the center of the burning part, and is burned at a low temperature around the hot part and dried, and then burned at the center and treated. ing. Accordingly, it is an object of the present invention to provide a treatment apparatus that can easily manage and maintain the apparatus without causing harmful components such as dioxin to be discharged together with exhaust gas when burning waste.

  Combustible combustible waste discharged from general small-scale business establishments is often collected by a collection vehicle of a waste disposal company and is collected separately from waste discharged from households. In many cases, the wastes are processed together in an incinerator or the like of an industrial waste disposal company. Also, as a general disposal method, it is collected together with waste discharged from ordinary households in a large-scale incineration plant and efficiently incinerated with a large amount of waste collected in one place. It is adopted, and incineration ash and incombustible components generated by the incineration are also landfilled.

  Waste discharged from small-scale offices, etc. is collected from paper waste and other combustible combustible waste, incinerated using a small incinerator installed in the company's premises, and incinerated. In many cases, a treatment method that only discards ash is used. Then, by incinerating the paper waste on its own premises, it is possible to contain the secrets inside the company without leaking the documents describing the secrets inside the company. A process that also serves to prevent the ejection is performed at the same time.

  However, when using a small combustion furnace to incinerate paper waste, wood chips and other combustible waste generated from small-scale establishments, an apparatus such as a conventional combustion processing apparatus It is said that harmful gases such as dioxins are likely to be generated because the combustion is not well controlled when using. In particular, when incinerating a mixture of various types of flammable waste using a small combustion furnace, incomplete combustion may occur due to the presence of water-rich waste or nonflammable materials. It is easy to generate | occur | produce, and as a result, many bad odors and off-flavors may be generated.

Furthermore, in the conventional small incinerator, the function of uniformly supplying air to the inside is not performed satisfactorily, and in some parts it burns at high temperature, while in other parts it becomes steamed at low temperature, In particular, a portion that burns at a temperature at which dioxins are easily generated is likely to be formed.
In addition, plastics that are discarded by being mixed with paper waste and wood chips cannot be completely burned in areas where they are burned in an incompletely steamed state, producing smoke and other odorous gases. There is also a problem that it often causes trouble to the surroundings.

Therefore, in order to deal with the problems of the generation of harmful gases and the generation of malodors as described above, it has also been proposed to dispose of using disposal means as disclosed in Patent Document 1. ing. In the conventional example, by using technical means for incineration of garbage at low temperature, it is possible to prevent the generation of harmful gases such as dioxin, malodors and odors, and it is possible to achieve downsizing of the equipment, It is described that many purposes of facilitating processing operations can be achieved simultaneously (see, for example, Patent Document 1).

  However, even if it is going to use the disposal method by the device disclosed in the above-mentioned conventional example, the technical means disclosed in the specification is questionable in feasibility. That is, the combustion method such as oxygen-free combustion disclosed in the conventional example is not disclosed so that it can be easily adopted. Therefore, from the above-mentioned publicly known document, there remains a problem that other people cannot actually use the invention, and the fact that flammable waste is actually rendered harmless is disclosed above. It is presumed that it cannot be done easily by using technical means. In addition, depending on the prior art, since both the supply mechanism for the gas body used for combustion and the exhaust gas discharge processing method are performed using a relatively troublesome processing method, the maintenance of the apparatus is maintained.

  With the configuration as described above, the heat treatment apparatus of the present invention can be installed near a source where combustible waste such as a relatively small amount of waste is discharged, such as a small-scale office, etc. It can be used to burn and treat garbage. And it can burn and process combustible waste little by little using a small processing device, without providing a large-scale large-scale incineration processing equipment. When heat-treating the combustible waste, air passing through a magnetic field is supplied to the central part of the combustion part and burned at a high temperature of about 1000 ° C., and gradually decreases from the central part to the outside. By adopting a method that forms an environment for combustion in the furnace and burns combustible waste, it is possible to perform processing without generating smoke or harmful gases.

  When treating combustible waste using the apparatus of the present invention, a combustion treatment form in which the waste in the surrounding portion is heated and dried with heat generated from the combustion portion at the center of the deposited combustible material Can be used. The combustible waste that has been thrown into the device is separated from moisture and volatile components by the time it reaches the combustion section in the center, and excess vaporized and volatile components interfere with combustion in the portion that burns at high temperatures. It is processed so that there is no. In addition, combustible waste as a subject to be subjected to the combustion treatment is not particularly limited in its kind or property, and all wastes discharged from general business establishments and households can be treated.

  In the apparatus of the present invention, a path for supplying air that passes through a magnetic field is provided, and the air that passes through the magnetic field is injected into the combustion part, thereby suppressing the generation of harmful gases and burning. Can do. And a combustion process effect | action can be easily controlled by restricting and dividing a combustion part and making it burn locally. In addition, in the stage before the object to be treated reaches the combustion part, the action of drying with the heat generated from the combustion part is performed, and the waste in the state where the volatile components are eliminated is combusted. Combustion requiring oxygen does not include a component that inhibits the combustion action. Furthermore, the volatile components generated in large quantities from the heated part before the workpiece reaches the combustion part passes through the side space defined around the processing furnace body and passes from the lower part of the furnace body to the combustion part. The flammable components are not discharged directly to the outside.

And, as described above, the combustible non-processed material is burned and processed, so that the exhaust gas generated from the combustion section can be discharged after performing the detoxifying process through the exhaust processing section. Become. In the exhaust treatment section, exhaust gas is first passed through water to remove floating components and gas components that can be dissolved in water, and then the bad odor is removed through a treatment device having a property of removing odors, and then outside air is removed. Therefore, the combustion gas can be processed using a relatively simplified processing means.
Furthermore, by installing an electric heater in the processing pipe line, it is possible to prevent odors and harmful gases from being discharged in a raw state. In addition to the above actions and effects, when the exhaust gas is treated, the generated liquid component is returned again to the heat treatment part, sent back to the side space of the furnace body, and again combusted in the combustion part. Thus, the harmful components are processed in a raw state so as not to be released toward the outside air.

  The configuration of the embodiment of the present invention will be described according to the illustrated example. The combustion treatment apparatus of the present invention described below can be treated by burning at a relatively low temperature without generating harmful gases and off-flavors, etc. in a small-scale establishment that discharges a relatively small amount of combustible waste. As an apparatus to be used, an apparatus configured to be usable is described as an example. In the following examples, combustible waste to be treated using a combustion treatment apparatus includes many combustibles such as wood waste, paper waste and garbage, and other combustible organic matter. It is possible to target such wastes, and those treated objects will be collectively referred to as combustible waste below.

  In addition, as long as it is an apparatus provided with a processing function so that the intended function and effect of the present invention can be achieved, the embodiment illustrated below is appropriately adapted to the environment of the processing plant. It can be improved and applied as a device with a changed detailed configuration. In the following explanation, the action and state of heat treatment of combustible waste such as paper waste discharged from the office department at a low temperature will be referred to as “fired”, but this also includes the steamed state as a whole. It is a general term. Therefore, unlike the case where the flame is blown up and burned, as in the case of burning in the open state, the remaining combustible components are processed in a steamed state in a closed environment while supplying a small amount of air. It is burned at a high temperature in the center, and only the remaining ash is processed.

When combusting the combustible waste, as in an example of an apparatus that burns and treats general waste or the like, the combustion portion at the center of the processing furnace is at a high temperature of about 1000 to 1200 ° C., It does not perform the process of burning. In the present invention, as in the example described below, the temperature environment in the furnace is set so that the combustion temperature becomes relatively low as the combustion temperature is increased in the central portion of the combustion portion, and as the distance from the combustion portion increases in the surrounding portion. Then, the treatment is performed in the state of steaming.
In addition, when performing the combustion treatment, components that easily volatilize such as moisture and gas bodies are gradually separated from the object to be treated, and a small amount of air is blown off at the center for burning the remaining combustible parts such as carbon components. While being supplied, a process of burning at the center of the combustion section is performed.

  The component evaporated or volatilized by the heat generated from the combustion part in the central part is cooled through a side space provided around the combustion part to be changed into a gas or liquid having a high specific gravity. Suppose that it is supplied from the lower part of the furnace body toward the combustion part and can be directly subjected to the combustion treatment. In the following description, such a process for burning combustible materials will be described using general expressions such as “combusting combustible waste”.

  Further, an exhaust treatment unit 50 for treating exhaust gas is provided behind the main body 9 provided with the processing furnace main body 10, and a deodorizing device 70 is disposed in parallel with the exhaust treatment unit. Through the heating mechanism provided in the deodorizing device 70, the combustion of the combustible gas contained in the exhaust gas and the deodorizing treatment for the gas component that generates a strange odor are performed and then discharged to the outside. ing. In the drawings of the present embodiment, for convenience of explanation, it is written that a part of the device is exposed from the cover, but actually, as described above, so as to cover the entire apparatus, It is surrounded and protected by an outer plate.

  An example of the configuration of the waste incineration processing apparatus 1 is illustrated in FIG. In the example of the waste incineration processing apparatus 1 described in FIG. 4, the processing furnace main body 10 that is provided in the main body 9 and burns and processes combustible waste is planarly viewed as described in FIG.

Since the processing furnace main body 10 is configured to be covered with a double wall, the heat generated in the combustion section surrounded by the inner plate 12 does not directly heat the outer plate 11, but is present in the gap. The heat is not released to the outside of the main body 10.

In FIG. 4 illustrating an example of the configuration of the waste incineration processing apparatus 1, the processing furnace main body 10 for burning and processing combustible waste is substantially hexagonal in plan view as described in FIG. 3.

In addition, a switch for detecting the opening / closing of the lid may be provided in a hinge portion or the like that supports the lid 21 and the fan 44 may be operated in conjunction with an operation of opening the lid 21 with a handle. As mentioned above, by taking measures to prevent the smoke from being blown out by dealing with the opening and closing of the lid, the amount of combustibles in the furnace is reduced, and the entire waste is in a state of burning. Even when it is necessary to throw in the waste, it is possible to prevent the smoke and flame inside from blowing out from the opening, and the dust throwing operation can be performed safely.

  Further, although the processing furnace body 10 is not disclosed in FIG. 4, as shown in FIGS. 6 and 7, which will be described later, the processing furnace body 10 is configured so as to have a gradually decreasing cross-sectional area from the top to the bottom.

Further, since the upper portion of the air supply nozzle 33 is covered with a cover 34 as shown in the figure, the dust does not directly hit the nozzle, and the necessary minimum amount of air is applied to the dust. Supply a good combustion environment.

  In the combustion section A in the furnace for combusting the combustible waste, at a high temperature of about 1200 ° C. in a state where there is little supply of air taken from outside through the nozzle 33 of the air supply device 30 toward the lower portion of the central portion. Combustion action is performed. In the outer part B of the high-temperature combustion part A, the smoldering is performed at a low temperature (steaming process) in a state where the temperature gradually decreases, and combustion is performed in a state where a small amount of oxygen is supplied. The In the low-temperature heating part B, the heat generated from the high-temperature combustion part in the central part is in a state where the moisture of the object to be processed and the volatile components are separated from the solids, and the solids with reduced deposition, It is supplied toward the high temperature combustion section A. Further, the remaining solid matter burned is deposited at the lower part of the combustion section and is discharged as needed. This combustion residue is an ash component that is a general burning residue, an inorganic material such as clay and ceramics that does not burn, metal components, etc., and the remaining residue that cannot be burned has an appropriate amount When collected, the screw 26 provided at the lower part of the processing furnace is driven to open the lid 28 of the opening provided on the bottom plate and discharge it to the lower part.

  The outside air supplied to the combustion section A comes through a magnetic field path 32 provided in the air supply device 30, and a part of the air component is supplied in an ionized state through the magnetic field. Will be. The use of oxygen ionized through the magnetic field for combustion produces the effect that the generation of harmful gas from the combustion part can be suppressed as much as possible, as is generally believed that combustion efficiency can be improved. . Therefore, in the magnetic path portion exposed outside the combustion part, the N and S poles of the permanent magnet are arranged in the pipe through which the air passes so that the air flows between the formed magnetic fields. Yes. And the air by which the air attracted | sucked in the combustion process part through the said pipe is supplied through a magnetic field, The air partially ionized through the magnetic field is used for combustion.

  As described above, combustible waste is generated in the combustion layer A by using air supplied from the two air supply devices 30 and 30a and air supplied from the lower part of the surrounding space 13 of the furnace (a part of the combustion gas). The action of burning is performed. In the combustion layer A, it is considered that combustible waste is mainly combusted by positioning the tip portion of the nozzle in the combustion processing unit and supplying air to the center of the combustion layer A. In this embodiment, the action of burning and treating the combustible waste inside the furnace body 10 is performed in a concentrated manner in a portion where the outside air that has passed through the magnetic field is concentrated. The air supplied from each of the air supply members is fed toward the center of the combustion section A, and the air is supplied in such a manner that outside air is intensively supplied toward the combustible waste accumulated inside. It is assumed that the combustion action is performed.

  Furthermore, in the upper part of the combustion part A, the heat which generate | occur | produces from a combustion part is applied with respect to the low-temperature heating part B of the upper part, and the process which dries combustible waste is performed. Therefore, in the combustion layer A, since it is not necessary to burn after combusting the water from the combustible waste, the heat treatment action in the combustion layer can be performed efficiently. By the combustion treatment in the combustion part, only the unburned ash component and the non-combustible component fall and accumulate in the lower space. As described above, as the combustible waste burns, new processed products are sequentially lowered from above. And in the combustion layer A in which the air which passed the magnetic field from an air intake member is blown in, after the combustible waste is carbonized, the process which supplies and burns a small amount of air is performed.

  In addition, as described above, in the upper part of the combustion layer A, an action of dry distillation at a temperature slightly lower than the combustion temperature is performed in addition to the process of evaporating moisture in the heating unit B. Furthermore, in the upper heating part C above the heating part B, the waste is heated at a lower temperature to separate the water evaporated at a low temperature from the combustion components, and the waste introduced from the inlet 20 is treated. The additional supply is sequentially supplied to the uppermost charging zone D of the furnace 10, and is gradually lowered and given a drying action as it is burned at the lower portion, and is supplied toward the combustion zone. In the heat treatment section, combustion is managed so that no harmful gas components such as dioxin are generated.

  Further, even if such harmful gas components are generated from a part of the combustion part, the combustion gas is exhausted through the part where it is intensively burned at a high temperature, so that the tyoxin is decomposed by heat. Such chemical treatment is automatically performed automatically. Then, exhaust gas is discharged from the chimney 71 through the deodorizer 70 as a detoxified gas component. Therefore, using a combustion device with a simple configuration, uncombusted gas or harmful gas generated from the heat treatment section is suitable for decomposing the surrounding gas without taking specially complicated process solutions. By flowing through the deodorizer 70 while touching a portion having a temperature suitable for processing gas or the like, an action of automatically decomposing is added.

  A portion for storing combustion debris is provided in the lower portion of the combustion processing unit 10, and the function of receiving and storing the remaining ash that has been burned and the liquid component generated from combustible waste is stored in the combustion unit. The lower part is burdened. Further, in the gap 13 around the furnace provided so as to surround the combustion processing unit 10, moisture and dry distillation gas components generated from the combustion gas and combustible waste are collected, and the gas comes into contact with the low temperature portion of the outer wall 11. As the specific gravity increases, it gradually descends and moves to the lower part. The lower part is temporarily held in a state absorbed by the combustion residue, but is vaporized again by the heat transmitted from the combustion part, or is sucked up to the combustion part by capillary action. Most of the liquid component accumulated in the portion is moved toward the combustion layer A and is heat-treated.

  Therefore, even if other liquid components such as moisture, tar components, and pyroligneous acid liquid accumulate in the lower portion of the combustion processing unit 30, it is considered that there is no problem with processing of burnt residue containing those components. . In addition, it is considered that the occurrence frequency of the state in which a large amount of the liquid component is contained in the burning residue accumulated in the lower portion is very low. Then, when a state where the burnt residue cannot be thrown away occurs, once again mixed with new combustible waste, the remaining residue is burnt again, and the detoxified waste is discarded. It will be. Further, the exhaust gas generated from the combustion part is only discharged toward the space 13 around the furnace, and a part of the exhaust gas is directed from the furnace peripheral space 13 toward the deodorizer 70 as the exhaust treatment part. Discharged.

  In the apparatus of the present invention, means for applying magnetism to the air supply device is provided in the path for supplying the combustion air, but actually, the outside air is left as it is without passing through the portion to which the magnetism is applied. If it supplies to a combustion part, in this apparatus, it cannot be made a favorable combustion state in a combustion part. On the other hand, a combustion state as described in the specification can be obtained by providing a magnet of about 4000 Gauss in the air supply passage and passing combustion air between the NS magnetic poles. It was made. Furthermore, by providing an exhaust treatment unit as an exhaust gas treatment device, it easily removes dust and unburned gas components generated in the furnace, and further contains sulfur, which is a major pollution problem if discharged as it is Gas components and other harmful gas components can be removed to such an extent that they are hardly detected.
