[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incineration product extraction method and apparatus for incinerating waste such as sawdust, planer waste, chips, paper waste, plastic waste, food waste, and the like.

0002

[Prior Art] Conventional garbage incinerators attempt to completely burn garbage, so even if they are large and expensive facilities, their processing capacity is small, dust removal equipment has high equipment costs, and the incineration products are just like garbage. Therefore, it was of no use value. In particular, in the past, the temperature inside the furnace was high because the purpose was to achieve complete combustion.
Since the treatment requires a long time, the treatment capacity is small, and the equipment and operating costs are high. Furthermore, even though conventional waste incinerators have large and expensive removal equipment, large amounts of air polluting gases such as HCl, COX, NOX, and SOX are released into the atmosphere. In addition, there has been a technology to remove dust by washing flue gas with water in a shower or by spraying it into water, but incineration products tend to float to the surface, especially from small and lightweight materials such as sawdust, planer scraps, paper scraps, and foamed plastics. If the dust contains soot and dust with There were many problems as the loss was large and the load on the smoke evacuation system became excessive. Furthermore, the soot and dust captured in the past is so fine that it is difficult to handle and dispose of it. Furthermore, since the incinerator was burned at high temperatures, the furnace body was easily damaged, and the cost of replacing furnace materials such as firebricks and boiler tubes was high.

0003

[Problems to be Solved by the Invention] The present invention provides an incinerator for incinerating waste such as sawdust, planing scraps, chips, paper scraps, plastics, and kitchen waste, which has high dust removal efficiency, and which uses HCl,
The primary objective is to provide a method that is highly efficient in removing air polluting gas components such as COX, NOX, and SOX, requires low equipment costs, has a long furnace life, and regenerates and extracts this waste as a resource. . A second object of the present invention is to provide such a device.

0004

[Means for Solving the Problems] The present invention is illustrated in FIGS. 1 to 4.
This will be explained below based on an example. (1) The present invention involves inserting the material to be incinerated into small pieces and lime powder into a furnace, igniting it with an ignition burner flame and a forcibly stirred atmosphere of 300°C or higher, and tilting the material to be incinerated. By detaching from the tilting shelf 18 that can be rotated and floating, the opportunity for contact with the furnace atmosphere is increased, and the organic substances are fired to the extent that they remain, and moisture containing ammonia is added to this furnace atmosphere to Ammonia and waste gas components are allowed to react while suppressing and adjusting the temperature rise and the degree of burning of the material to be incinerated,
This incineration product extraction method is characterized by washing this waste gas with ammonia water or slaked lime water.

[0005] The material to be incinerated is cut or crushed into small pieces so that it can be easily transported by air pressure and speeds up the reaction rate, and is ignited using an ignition burner flame and an atmosphere in the furnace of 300° C. or higher that is forcibly stirred. The material to be incinerated is made into small pieces, so
Most of them rapidly evaporate moisture in an atmosphere of 300°C or higher and begin to ignite or carbonize. The burner flame reaches a high temperature depending on the type of fuel, but the temperature of the atmosphere inside the furnace is set so that it does not melt the glass and prevent equipment trouble due to its adhesion, and because it allows the use of inexpensive heat-resistant steel and prevents damage to that part.
Preferably, the temperature is kept below 800°C. The material to be incinerated is heated to 300°C by gravity or forced stirring by tilting the tilting shelf.
The above-mentioned atmospheric flow causes the organic material to be separated from the tilting shelf 18 and dropped or floated in the atmosphere in the furnace to increase the chance of contact with the atmosphere, and is fired in a short time to the extent that the organic material remains. Moisture containing lime powder and ammonia is added to the atmosphere inside the furnace, and ammonia and waste gas components are reacted while suppressing and controlling the rise in the atmosphere temperature and the degree of burning of the materials to be incinerated. Alternatively, it is washed with slaked lime water to remove air polluting gases such as HCl, COX, NOX, and SOX.

(2) As shown in FIGS. 1 and 2, in the present invention, lime powder is added to the material to be incinerated 3 prepared into small pieces into the combustion zone 2 of the incinerator 1, and the mixture is injected together with combustion air 4. The material to be incinerated is ignited by the ignition burner flame that flows together with the material, and the material to be incinerated is separated from the tilting shelf 18 that can be tilted and made to float, thereby increasing the chance of contact with the atmosphere in the furnace. is increased and fired to the extent that organic substances remain, and the fallen matter 9 on the hearth is washed and extracted with water, and moisture is added to the atmosphere in the furnace to suppress the rise in atmospheric temperature and the degree of firing of the matter 3 to be incinerated. reacting ammonia with waste gas components in a controlled manner and washing the waste gas with ammonia water or slaked lime water;
Ammonia, lime, or caustic soda is added to this outside tank water 6, and sludge components containing soot dust in this outside furnace tank water 6 and the above-mentioned hearth cleaning water are extracted and dehydrated. Preferably, the method for extracting the incineration product is characterized by successive granulation molding.

In other words, in addition to the technology described in item (1), the present invention automatically washes and extracts fallen objects on the hearth with water, and adds moisture to the atmosphere inside the furnace to increase the atmospheric temperature and reduce the amount of incinerated materials. Ammonia and waste gas components are made to react with each other while suppressing and adjusting the degree of burning of the waste gas to facilitate removal of the regulated substances, and the material to be incinerated is burnt to the extent that organic substances remain in the atmosphere of the waste gas. By doing this, a large amount of incineration products can be automatically extracted out of the furnace without going through the flue. The hearth, which is most easily damaged by the conventional method, becomes less likely to be damaged by the method of the present invention because the temperature does not rise, and its lifespan can be significantly improved.

[0008] In the present invention, the generated waste gas is floated out of the water in the aquarium, and when it is released into the atmosphere from the chimney, heat exchange is performed between it and the high-temperature waste gas extracted from the furnace. It is desirable to increase the temperature and increase the buoyancy force within the chimney. The incinerator that includes this dust removal device is small and has a simple structure, so the equipment cost is low, and the incineration product that has been incompletely combusted to the extent that organic components remain can be used as a fertilizer or soil conditioner, for example, as described below. occurs. Especially when the incineration products include light or large items such as sawdust, planer scraps, paper scraps, and foamed plastics that tend to float to the surface, since the incineration products are not filtered through a filter, they can be easily clogged. There is no fear that this will occur, and the load on the smoke evacuation device 8 will not become excessive due to clogging. Furthermore, the captured incineration product is easy to handle, and the handling becomes even easier if it is granulated as described below. Furthermore, since the combustion temperature in the incinerator is low, the furnace body is less likely to be damaged, there is no need to use expensive refractory bricks, and the furnace body can be easily repaired.

[0009] In the water tank outside the reactor, where the waste gas is pumped and dispersed as small bubbles, ammonia, lime, or caustic soda is added to capture and deodorize HCl and COX in the flue gas, and lime is added to the incineration products. etc. to penetrate. If ammonia water is added to this water tank outside the reactor, NOx
It can capture SOX and produce fertilizer components. Furthermore, the sludge components containing soot and dust in this outside-furnace water tank water and the above-mentioned hearth washing water are extracted and dehydrated while circulating them, and then granulated. For this granulation molding, it is desirable to add a resin component of about 2% or more of the total weight as a binder, but if resin components such as wood or plastic remain in the material to be incinerated during firing, , these resin components serve as good binders. Further, when the extracted sludge component is brought into contact with waste gas and dried, the resin component in the waste gas is captured on the surface of the extract and becomes a good binding agent. COX and SOX captured from flue gas serve as good fertilizers and soil conditioners, such as calcium carbonate and ammonia sulfate.

[0010] Obtaining waste gas with an air/fuel ratio (air-fuel ratio) that causes incomplete combustion to the extent that organic substances remain;
As this waste gas is cooled, the water vapor in the waste gas is agglomerated with soot dust as the core, and this waste gas is forced to the bottom of a small-bubble plate with through holes in the water tank outside the incinerator, where it is dispersed as small bubbles. The waste gases thus obtained are collected, cooled and dehydrated to yield useful gases, such as combustible gases. This waste gas contains carbon monoxide and hydrocarbon gas as useful components, and can be used as a heat source or raw material for chemical synthesis.

(3) As illustrated in FIGS. 1 and 2, the present invention includes a pipe 23 for pneumatically transporting the incineration material 3 prepared into small pieces to a cyclone-type furnace side tank 22, and a pipe 23 for discharging excess air. Control valve 2 that adjusts the exhaust pipe 24 and the flow rate of the material to be incinerated 3
5, a press-in pipe 26 that adds lime powder to the material to be incinerated 3 and presses it into the furnace together with combustion air 4, an ignition burner 11 in which the material to be incinerated and the flame flow together, and a waste gas 30 forcibly stirred through the gap of the tilting shelf 18.
This incinerator is characterized by being equipped with a forced stirring fan 21 at 0° C. or higher, a tilting shelf 18 that can adjust the tilting shelf gap by changing its inclination angle, and other essential equipment as an incinerator.

In other words, the material to be incinerated 3 can be automatically sent to the cyclone type furnace side tank 22 by air pressure using an inexpensive device, and the cyclone type furnace side tank 22 separates the air and the material to be incinerated. Excess air is discharged from the exhaust pipe 24. The flow rate of the material to be incinerated 3 is controlled by a control valve 25, and the material to be incinerated is forced into the furnace together with the combustion air 4. Since the ignition burner is combusted so that the incineration flow and the flame flow together, the material to be incinerated 3 can be easily ignited, and the material to be incinerated can be suspended in the atmosphere for a long period of time to promote its burning. If the waste gas is forcibly stirred through the gap of the tilting shelf 18 by the forced stirring fan 21, the temperature inside the furnace can be easily maintained within a predetermined range, and the materials to be incinerated are circulated together with the waste gas, thereby promoting firing. At this time, by changing the inclination angle of the tilting shelf 18 and adjusting the tilting shelf gap, the amount of waste gas circulation can be adjusted. The materials 3 to be incinerated fall and accumulate on the tilting shelf 18, but when the burning progresses on the tilting shelf 18, which is at a high temperature close to the furnace atmosphere temperature, and the material becomes lighter, it is blown away again by the forced stirring gas. The material to be incinerated 3 that has fallen onto the tilting shelf 18 can be dropped or blown away by periodically tilting the tilting shelf 18. It is preferable to change the inclination of the tilting shelf 18 by sequentially changing the position as the waves advance. As described above, it is desirable that the tilting shelf be multi-tiered, and it should have the function of adjusting the forced flow inside the furnace, the function of a grate, and the function of dropping the materials to be incinerated.

(4) As illustrated in FIGS. 3 and 4, the present invention includes a plurality of inclined tubular rotary furnace bodies 29 each having a longitudinally extending shelf portion 18 on the inner surface, and is equipped with a sieving grid 34. The movable ring 31 is connected by a movable ring 31 that rotates or swings, and the movable ring 31 has a discharge port 3 for discharging the residue on the sieve from the movable ring.
3, a furnace insertion chute 32 for inserting the material to be incinerated into the furnace and a flue 5 leading to the chimney are connected to the high position side of the tubular rotary furnace body 29, and the low position side of the tubular rotary furnace body 29 The incinerator is equipped with an ignition burner 11 and an incineration product extraction port 35 on the side, and is also equipped with other essential equipment as an incinerator.

In other words, the present invention provides a shelf section 1 extending in the length direction.
By rotating a plurality of tubular rotary furnace bodies 29 that are connected to each other so as to be inclined in the vertical direction, the objects to be incinerated are lifted up on the shelf section 18 and dropped from the shelf section 18, and the atmosphere inside the furnace is forcibly stirred. At the same time, the chance of contact between the atmosphere inside the furnace and the material to be incinerated is increased. Next, in the movable ring 31, preferably, the lump of the material to be incinerated is pulverized by a crushing ball 30, and then sent to the next tubular rotary furnace body 29 for efficient firing. The material to be incinerated is inserted through the furnace insertion chute 32 on the higher side of the tubular rotary furnace body 29, and advances to the exit side by stirring and tilting within the tubular furnace body due to its rotation. A flue leading to a chimney is connected near the furnace insertion chute, and the waste gas exchanges heat with the material to be incinerated over almost the entire length inside the tubular rotary furnace body 29. The tubular rotary furnace body has an ignition burner 11 and an incineration product extraction port 35 at a lower position,
Preferably, a fan 21 for forcibly stirring the waste gas and a circulation path for circulating the waste gas are provided. Preferably, the waste gas and incineration products are post-treated in the same manner as described above.

(5) As shown in FIGS. 3 and 4, the present invention
A plurality of inclined tubular rotary furnace bodies 29 each having a shelf portion 18 extending in the length direction formed on the inner surface thereof are sieved with a grid 3 for crushing balls 30.
4 and connected by a movable ring 31 that rotates or swings, and is equipped with a discharge port 33 for discharging the sieved material from the movable ring 31. The chute 32 inserted into the furnace is connected to the flue 5 leading to the chimney, and the lower side of the tubular rotary furnace body 29 is equipped with an ignition burner 11, an incineration product extraction port 35, and other inevitable equipment as an incinerator. It is an incinerator characterized by being equipped with.

In other words, in addition to the technique described in item (4), the material to be incinerated is crushed by the crushing balls housed inside the movable ring part of the connecting part of the tubular rotary furnace body as it rotates or swings. The material to be incinerated is dehydrated and partially calcined at the time of pulverization, so it is easily pulverized, and the surface area of the pulverized material to be incinerated increases and the temperature easily rises, thereby increasing the firing rate. The residue on the grid is removed from the upper residue outlet 33 at this position after a predetermined period of time has elapsed.
taken from.

[Example 1] Using the apparatus shown in Fig. 1 or 2, lime powder is added to the material to be incinerated, and while it is pressurized into the furnace together with combustion air, the gas inside the furnace is locally circulated as shown by arrow Y. Moisture containing ammonia is added to the atmosphere inside the furnace to suppress and control the rise in ambient temperature and the combustion of the materials to be incinerated, and to adjust the degree of calcination of the product to such an extent that organic components remain, thereby increasing the yield. In addition to increasing the temperature of the furnace, it also prevents the temperature of the furnace body from rising and extends the life of the furnace. Also, air polluting gases such as HCl and COX
, NOX, SOX, etc., are absorbed or adsorbed into this high-temperature active water vapor. Preferably, the dust in the waste gas is wetted to improve its affinity with water, and the waste gas is washed with ammonia water or slaked lime water to facilitate trapping of the dust in water. The material to be incinerated is sheared, cut, or crushed into small pieces that can be easily pumped by air, and if necessary, the properties of the material to be incinerated are determined by pretreatment such as drying and blend adjustment to the extent that it can be easily pumped by air. Adjust it.

[0018]

[Embodiment 2] Using the apparatus shown in FIG. 1 or 2, the material to be incinerated 3 prepared into small pieces is injected into the combustion zone 2 of the incinerator 1 together with combustion air 4, and the material is flown inside the furnace. The material to be incinerated is ignited by an ignition burner flame that flows together with the material to be incinerated, and the material is burned in an atmosphere circulating through the gap between the partition walls in the furnace to the extent that organic substances remain. In addition to washing and extracting the fallen material 9 on the hearth with water, moisture is added to the atmosphere inside the furnace to suppress and control the rise in ambient temperature and the degree of sintering of the material 3 to be incinerated, while reacting with ammonia and waste gas components. As the waste gas is cooled in 5, the water vapor in the waste gas is condensed with soot dust as the core,
This waste gas is forced to the lower part of the small bubble forming plate 7 having through holes in the water tank water 6 outside the incinerator, and is dispersed and floated as small bubbles. Caustic soda is added, and the sludge components containing soot dust in the water in the water tank outside the furnace and the water for cleaning the hearth are extracted and dehydrated while circulating them, and then granulated. The waste gas is force-fed to the bottom of a small-bubble plate 7 having through-holes in a water tank 6 outside the incinerator, and is dispersed and floated as small bubbles.
The waste gas thus obtained is collected, cooled and dehydrated to obtain a combustible gas.

[0019]

Embodiment 3 In Embodiment 1 or 2, moisture is added to the atmosphere in the furnace to suppress and control the increase in the ambient temperature and the combustion of the material to be incinerated 3, while promoting the production of iron suboxide. This waste gas is forced into an outside water tank 6 containing calcium, the sludge components containing soot and dust in this water are dehydrated, and preferably, the product is granulated and molded.
70% residual carbon, 5% to 50% organic carbon, 1% to 10% calcium, and 0.1% to 10%
An alkaline incinerator extract having a pH of 10 or more is obtained, which contains iron suboxide and iron suboxide in a dry weight ratio. Lime powder is added to the material to be incinerated, which has been prepared into small pieces containing iron pieces, and is injected together with combustion air into the combustion zone of the incinerator, and this is then incompletely combusted in the furnace atmosphere with added moisture. , Fe
To efficiently generate iron suboxides such as FeO and Fe3O4, which have a lower oxygen ratio than 2O3. Then, the fallen objects on the hearth are washed and extracted with water, and the rise in water temperature adds moisture to the furnace atmosphere to protect the furnace body by keeping the combustion zone atmosphere temperature at a relatively low temperature, preferably 300 to 800 degrees Celsius. , suppresses and adjusts the combustion of incinerated materials. This waste gas is then forced into an outside water tank containing calcium, and the sludge components containing soot and dust in the water are dehydrated, followed by granulation. A product is thus obtained which contains, in dry weight proportions, 10 to 70% residual carbon, 5 to 50% organic carbon, 1 to 10% calcium and 0.1 to 10% iron suboxide.

[0020] The residual carbon of the incompletely burned incineration material thus obtained, that is, the carbon remaining after the thermal decomposition of organic matter, has a deodorizing effect like activated carbon, and can also be used as a variety of fertilizers, soil conditioners, etc. Easily adsorbs and retains active ingredients such as insecticides,
The unburned part in the center itself becomes an organic fertilizer, easily impregnating and retaining active ingredients, and also serves as a base for residual carbon, making it easy to handle and prevent its dissipation. Calcium to be added to the outside water tank is easily available at low cost as CaO or Ca(OH)2, and these are used as HCl and COX scavengers, soil acid neutralizers, and insecticides. When iron pieces are heated and oxidized in a conventional incinerator, Fe2O3 is generated all at once due to the supply of sufficient oxygen at high temperatures of over 900°C.
When oxidized in a pyrolyzed steam atmosphere at 300 to 800° C. as in the present invention, iron suboxides such as FeO and Fe3O4 are generated at a high rate due to oxygen in the nascent stage even at a relatively low temperature. When iron suboxides such as FeO and Fe3O4 are applied as fertilizers or soil conditioners, they gradually oxidize and eventually become iron oxide, or Fe2O3. During this oxidation reaction process, iron is easily absorbed by plants, making them rich in iron. Plants are obtained and the reaction is exothermic and promotes plant growth.

[0021] The lower limit of the component content of the incinerator product as a fertilizer or soil conditioner of the present invention is an amount sufficient to achieve the purpose as a fertilizer or soil additive, and the upper limit is as described above. This is the value that can be easily obtained and most recommended within a range that does not impair the purpose of the technology. Therefore, this upper limit can be expanded as the technology improves or the purpose changes. In any case, preferably in addition to the above conditions, a shower is injected into the waste gas at the rear of the flue to clean and humidify it, and the trapped soot and dust can be discharged from the exit end of the flue along with the cleaning water. . In the present invention, by increasing the pressure in the combustion zone of the incinerator, the internal volume of the incinerator can be designed to be small, and the volatile components in the incinerated materials can be prevented from dissipating, which is effective in increasing the yield of incinerated products. There is.

[0022]

[Effects of the Invention] According to the present invention, the incinerator that incinerates sawdust, planer scraps, chips, paper scraps, plastics and other garbage has high dust removal efficiency and eliminates HCl, COX, NOx, etc.
It is possible to provide a method that releases less air polluting gas such as , SOX, etc., has low equipment costs, has a long furnace life, and uses this waste as a resource to extract products as useful substances. Furthermore, it becomes possible to provide a method for extracting captured soot dust and incineration products as a good fertilizer or soil conditioner, and a method for extracting waste gas as a fuel gas or raw material for chemical synthesis. Furthermore, the present invention can provide an apparatus for carrying out the method of the present invention. According to the present invention, the materials to be incinerated are combusted to the extent that they are incompletely combusted, so the incinerator has a large processing capacity even though it is small. Since the temperature inside the furnace can be maintained at a relatively low temperature through incomplete combustion and the addition of steam, it is possible to extend the life of the furnace material and use inexpensive furnace materials. In addition, since the combustion radiant heat is blocked by the partition wall inside the furnace, there is little damage to the hearth and furnace walls, and since the materials to be incinerated are in the form of small pieces, there is no impact from falling of lumpy materials to be incinerated, so there is no damage to the hearth or grate. Cheaper materials can be used for these furnace materials. In addition, the furnace partition wall can have the function of a rectifying plate for the waste gas in the furnace, and the furnace partition wall can change its inclination angle to adjust the gap between adjacent furnace partition walls to flow the waste gas. It is possible to adjust the amount of dust that has accumulated on it and to make it fall. By circulating the waste gas through the gap between the partition walls in the furnace as in the present invention, it becomes easier to maintain the temperature and atmosphere inside the furnace at desired values throughout, and the combustion time and reaction time can be lengthened. This will make it easier to achieve your goals.
