The present invention relates to a waste melting treatment method using coke for an apparatus and a waste melting furnace.

Coke is used as a heat source and reducing agent in steelmaking and waste melting furnaces, but because it uses a large amount of caking coal as a raw material, it is not only expensive, but coke has a high CO ₂ emission. Therefore, from the viewpoint of suppressing global warming, measures such as the use of waste and biomass are required.

  A method for producing carbide using waste has been proposed. For example, Patent Document 1 discloses a method of producing a mixed fuel by carbonizing livestock manure and sewage sludge and mixing and pulverizing the resulting carbide with coal. Patent Document 2 describes a method for producing molded charcoal for fuel obtained by molding organic matter such as agricultural waste, livestock excrement, and waste plastic into a dry heat treatment chamber and carbonizing between charcoal powders.

  FIG. 4 is a process schematic diagram showing the method for producing a molded lump described in Patent Document 3.

  The raw material is charged from the upper part of the shaft furnace type carbonization furnace 1 and is carbonized in a high temperature reducing atmosphere in the furnace. By dry distillation, the volatile matter in the raw material becomes combustible gas, combustible dust and tar, and is discharged from the upper part of the shaft furnace. The dry distillation residue from which the volatile components are volatilized out of the raw material is discharged by the screw conveyor 2 installed at the lower part of the shaft furnace type dry distillation furnace 1, and the iron content and other metals and debris mixed with the raw material are removed by the magnetic separator 3 and the separator 4. After the removal, the sieve is sorted by the sieve sorter 5.

    Under the sieve, the mixer 6 kneads a soft pitch that becomes a binder, heats it together with the dry distillation residue to 150 ° C., and is pressure-molded by the molding machine 7. The molded product 8 is returned to the shaft furnace type dry distillation furnace 1 together with the raw material, and the binder is coke by dry distillation to produce a strong molded lump. On the other hand, the combustible dust in the gas is collected from the combustible gas volatilized from the upper part of the shaft furnace by the dust remover 9, and the collected combustible dust is introduced into the sieve sorter 5 and molded together with the sieve bottom. And carbonized again.

The combustible gas from which the combustible dust is removed becomes a clean gas by tar reforming by the catalyst 10 and can be generated by introducing this gas into the gas engine generator 11.

  In the cited document 3, when a general waste or the like is used as a raw material, a residue generated by dry distillation has a low calorie and a high ash content of 2000 to 3000 kcal / kg. When this residue is molded and carbonized, the amount of heat is insufficient as coke.

  Coke for iron making is pulverized and dry-distilled, and the coal softens and melts in the process, and particles are bonded to each other to form a strong structure and develop strength as coke.

Moreover, waste melting furnace coke obtained from waste by the present invention was charged, alone or basicity adjusting agent, by melting treatment by hot combustion to minimize the external energy input, CO ₂ emissions The amount can be reduced.

  FIG. 1 is a process schematic diagram showing a method for producing coke for a waste melting furnace according to the present invention.

  As in the prior art shown in FIG. 4, waste containing organic substances such as general waste, building mixed waste, sewage sludge, paper sludge, and livestock manure is charged from the top of the shaft furnace type dry distillation furnace 1. The dry distillation is performed in a high-temperature reducing atmosphere in the furnace. Various dry distillation apparatuses such as a rotary kiln, a shaft furnace, and a fluidized bed can be applied to the dry distillation furnace 1.

  By dry distillation, the volatile matter becomes combustible gas, combustible dust and tar, and is discharged from the upper part of the shaft furnace type dry distillation furnace 1. The dry distillation residue from which volatile matter has been scattered is discharged by a screw conveyor 2 installed at the lower part of the shaft furnace type dry distillation furnace 1. After iron content and other metals and rubbles mixed in the dry distillation residue are removed by the magnetic separator 3 and the separator 4, the sieve is sorted by the sieve separator 5.

  The dried product under the sieve, the calorific value adjusting material, and the binder are kneaded by the mixer 6.

  The dry distillation product under the sieve of the sieve sorter 5 measures and analyzes at least one item of calorific value, fixed carbon, ash content, volatile content, and carbon content by the analysis / measurement device 12, and generates heat according to the result. Adjust the amount of addition of the amount adjusting material. Carbides such as general wastes have a low calorific value, and even if they are molded coke, the calorific value is low, and the calorific value is insufficient as coke for waste melting furnaces. The amount of heat generated can be applied as coke for a waste melting furnace. The calorific value adjusting material is, for example, one of coal, sawdust, rice straw or a mixture thereof, and pulverized to 3 mm or less. These calorific value adjustment materials not only have a high calorific value of the carbonized product, but also coal softens and melts during carbonization, and sawdust and rice straw contribute to an increase in coke strength by the effect of lignin that precipitates during pressure molding. To do.

  The addition amount of the calorific value adjusting material is adjusted according to the result of measuring / analyzing at least one item of calorific value, fixed carbon, ash content, volatile content, and carbon content of the raw carbonized material.

  FIG. 2 (a) is a graph showing the relationship between the calorific value of the dry distillation product obtained in the first carbonization and the addition amount of the calorific value adjusting material added to this dry distillation, and (b) was obtained in the first carbonization. It is a graph which shows the relationship between the ash content of a dry distillation thing, and the calorific value adjustment material addition amount added to this dry distillation thing. If the calorific value of the dry distillation product obtained by the first dry distillation is large, the amount of addition of the calorific value adjustment material is small. There is a need to do more.

  Since the properties of general waste dry distillate and wood biomass dry distillate are significantly different, by measuring and analyzing at least one of the above items, the properties of the dry distillate can be controlled and the coal mixture adjusted. It is possible to stabilize the calorific value of the molded coke.

  As the binder, at least one of tar, pitch, lignin, phenol resin, and phenol is used. The tar content can be condensed and recovered from the dry distillation gas generated during the dry distillation and used as a binder, and the cost of the binder can be reduced. When particles are bonded as a binder and carbonized, the binder between the particles is carbonized, and the bonding force between the particles is maintained. In addition, in the method for producing blast furnace coke, it is known that by adding tar or the like to cheap steam coal, it exhibits softening and melting properties comparable to those of strong caking coal. Coal as a quantity adjusting material softens and melts and contributes to an increase in strength of molded coke. The added amount of the binder is 2 to 50% (weight ratio). For example, in the case of a binder having a high viscosity at room temperature such as tar and pitch, the binder can be heated to 50 to 200 ° C. The calorific value of the dry distillation product and the amount of the calorific value adjusting material added differ depending on the properties of the waste to be carbonized. For example, when wood is carbonized, the calorific value is high, but the density of the carbonized material is small, and the amount of binder added is about 40%. On the other hand, when sawdust is used as the calorific value adjusting material, since the lignin precipitated from sawdust serves as a binder, a binder addition rate of about 3% is sufficient.

  The kneaded product is heated and pressure-molded by the molding machine 7. Since the molding machine requires strength of the molded product, it can be applied to extrusion molding machines, double roll molding machines, injection molding machines, press molding machines, etc., but double roll molding machines capable of mass production. Is desirable.

  The molded product 8 is returned to the shaft furnace type carbonization furnace 1 together with the raw material, and is subjected to carbonization, whereby the binder is coke and a strong molded lump can be produced. The dry distillation temperature is 700 to 1200 ° C. When the carbonization temperature is 700 ° C. or less, the volatile content of the molded coke is 10% or more. When applied to a waste melting furnace, molded coke with a high volatile content collapses in a high-temperature reducing atmosphere at the lower part of the melting furnace and cannot form a high-temperature grate. Moreover, when the carbonization temperature is 1200 ° C. or higher, there is no great difference in the strength of the molded coke, which causes an economic problem. Therefore, it is desirable that the dry distillation temperature is 700 to 1200 ° C.

  On the other hand, the combustible gas scattered from the upper part of the shaft furnace collects the combustible dust in the gas by the dust remover 9, and the collected combustible dust is introduced into the sieve sorter 5 and molded together with the sieve bottom. And carbonized again. The combustible gas from which the combustible dust is removed becomes a clean gas by tar reforming by the catalyst 10, and can be used for power generation by introducing this gas into the gas engine generator 11.

  Further, by burning all or part of the combustible gas in the combustion furnace 13 to generate high-temperature exhaust gas and using this high-temperature gas as a dry distillation heat source of the dry distillation furnace 1, energy saving can be achieved. Further, the tar in the combustible gas can be condensed into the tar component in addition to the catalyst reforming, and can be put into the mixer 6 as a binder.

  The re-distilled dry matter on the sieve of the sieve sorter 5 has a high calorific value and is used as coke for a waste melting furnace having a low ash content.

  The coke for the waste melting furnace thus obtained is thrown into the waste melting furnace together with the waste, and the coke bed is formed with the coke for the waste melting furnace, and discarded. The product can be melt processed.

Conventionally, as a fuel for the waste melting furnace, high-cost iron coke is used, but only the waste melting furnace coke obtained from the waste according to the present invention is put into the waste melting furnace, By burning at a high temperature and melting the ash in the coke for the waste melting furnace, it is possible to minimize the amount of external energy input and to achieve a waste melting process with reduced CO ₂ emissions. At this time, depending on the ash content and basicity (CaO / SiO ₂ ) in the waste melting furnace coke, for example, by adding a basicity adjusting material such as limestone or silica sand, It is possible to stabilize the quality.

In this example, molded coke was manufactured by the manufacturing method shown in FIG. General waste discharged from households was used as a raw material. As shown in this figure, the general waste is charged from the upper part of the shaft furnace type dry distillation furnace 1, and the moisture is dried and dry distilled by the high temperature reducing atmosphere in the furnace. By dry distillation, combustible gas, combustible dust and tar are discharged from the upper part of the furnace.
The carbonization residue from which the volatile components are volatilized out of the raw material is discharged by the screw conveyor 2 installed at the lower part of the shaft furnace type carbonization furnace 1, and the iron content and other metals and debris mixed in the general waste are separated by the magnetic separator 3 and various kinds. After removal by the sorter 4, the sieve is sorted by the sieve sorter 5. Here, the particle size distribution of the product can be easily adjusted by changing the size of the knots, but in this example, the knots were set to 20 mm in accordance with a normal waste melting furnace.

  The calorific value under the sieve selected by the sieving machine was measured. In this example, a heat insulation cylinder type calorific value measuring device, which is a general calorific value measuring method, was used. Although this method was used here, most of the dry distillate is composed of fixed carbon and ash, so in addition to the calorific value, general carbon such as fixed carbon, ash, volatile, and carbon content It can be substituted by analysis.

  As a result of measuring the calorific value, the calorific value of the dry distillation product was 2800 kcal / kg. Therefore, based on FIG. 2 (a), 53% (weight ratio: external number) of coal (general coal) as the calorific value adjusting material and 15% of tar discharged from the coke oven as a binder (weight ratio: external) Number) was put into the mixer 6 and the inside of the mixer was heated to 150 ° C. and kneaded for 3 minutes. Here, the form of the mixer is not particularly limited, and a mixer suitable for the properties of the dry distillation product may be selected as appropriate.

  The kneaded material kneaded by the mixer 6 was put into a double roll molding machine 7 and subjected to pressure molding at a linear pressure of 2 t / cm to prepare a briquette. The molded product is returned to the shaft furnace type carbonization furnace 1 together with the raw material, and the coal is softened and melted by the carbonization, the bonding force of the particles is strengthened, and coke with the binder to produce a strong molded coke. it can.

  On the other hand, the combustible gas discharged from the upper part of the shaft furnace type distillation furnace 1 is separated into combustible dust in the gas by the dust remover 9, and the separated combustible dust is introduced into the node sorting machine 5 for saving. Mold with the bottom and dry distillation again. A part of the combustible gas from which combustible dust has been removed is burned in a combustion furnace at an air ratio of about λ = 1.0, and the exhaust gas having a low oxygen concentration and high temperature is blown from the bottom of the shaft furnace type dry distillation furnace 1 A heat source for dry distillation was used. In addition, some of the combustible gas is recovered by using a condenser, then further reforming tar that could not be condensed by a catalyst, and then generating power with a gas engine generator to drive the equipment. used. As a matter of course, this combustible gas can be used as a chemical raw material, or can be introduced into a waste heat boiler after combustion and generated by a steam turbine generator.

  Since the carbonization residue discharged from the screw conveyor 2 needs to be heated in the subsequent binder kneading process, the higher the temperature at the time of discharge, the more energy is saved. The dry distillation residue is cooled to 150 ° C. or lower, or is continuously arranged from the outlet of the screw conveyor 2 to the outlet of the molding machine 7 so that the passage of the dry distillation residue is airtight, and is inert inside, for example, nitrogen. By enclosing the gas, heating during binder kneading becomes unnecessary.

    Further, in the present invention, the layout of each facility is not limited to the layout as in the present embodiment, and can be appropriately changed according to the location conditions. For example, the air flow is carried under the sieve of the sieve sorter 5 Then, it is possible to put the charcoal kneaded and pressure-molded by the mixer 6 and the molding machine 7 disposed on the shaft furnace type carbonization furnace 1 as it is into the shaft furnace type carbonization furnace 1.

  In this example, the carbonization temperature was 800 ° C. At the beginning of the operation, only the sieving was discharged, and all were formed together with coal as the calorific value adjusting material and tar as the binder, and then re-distilled. Product coke remained on the sieve after about 4 hours from the start of raw material charging. Since the residence time of the shaft furnace type carbonization furnace is about 2 hours, it can be seen that the raw material of this example can be produced as a molded lump by dry distillation twice. Here, when another raw material is used or when the required particle size is different, only the number of dry distillation until it remains on the sieve will naturally increase and decrease, and no special operation is required.

  In this embodiment, the waste melting furnace coke produced by the method of the present invention is used in the waste melting furnace. As a method for treating waste such as general waste and industrial waste, for example, there is a waste melting process in which waste is dried, pyrolyzed, burned and melted in a shaft furnace type waste melting furnace to form slag and metal. is there.

  FIG. 3 is a process schematic diagram for waste treatment using the waste melting furnace coke according to the present invention. As shown in this figure, the waste melting furnace 22 is charged with waste coke and limestone as auxiliary materials from the top of the furnace via a charging device 23 of a double seal valve mechanism. Slag is discharged from the outlet 24 through the processes of drying, thermal decomposition, combustion, and melting. Some of the combustibles in the waste are carbonized and discharged as gas, and some are combusted by air and oxygen blown from the tuyeres at the bottom of the furnace, while the rest are combustible. It becomes dust and is discharged from the top of the melting furnace 22.

  The combustible gas and combustible dust discharged from the melting furnace 22 are combusted in the combustion chamber 25, heat recovery is performed in the boiler 26, and the generated steam is sent to the steam turbine / power generation device 27. The exhaust gas from the boiler 26 is separated into solid and gas by a dust collector 28 and discharged from a chimney 30 by a blower 29. The coke charged from the upper part of the waste melting furnace 22 is combusted by oxygen-enriched air blown from the lower tuyere 31 attached to the lower part of the furnace, and is discarded by forming a high-temperature grate at the lower part of the furnace. The ash content in the product is melted and made into slag.

In the present embodiment, only the waste melting furnace coke produced in Example 1 or the waste melting furnace coke and limestone as a basicity adjusting material are introduced from the upper part of the waste melting furnace 22 to produce waste. Oxygen-enriched air was blown from the lower tuyere 31 of the melting furnace 22. Table 1 shows the operating conditions of the melting furnace.

  When operated under the conditions shown in Table 1, the discharge of the melt was smooth and stable operation was possible. However, condition no. In No. 1, since the basicity of slag is as low as about 0.3, the viscosity of the slag is high, and in order to smoothly discharge the melt, it is necessary to increase the oxygen concentration of the oxygen-enriched air blown from the tuyere by about 4%. was there.
