Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an industrial waste containing oil and / or water, a waste containing almost no oil and water, or a waste requiring atomization treatment,
Waste that does not need to be treated is not limited by its type, properties, etc., and it does not require special treatment to obtain emulsification or stable suspension when mixing them. It relates to a method of reusing as fuel or the like. The method of the present invention is particularly suitable when industrial waste is used as an industrial fuel for a cement burning furnace, a coke oven, or the like.

[0002]

2. Description of the Related Art Industrial wastes include a wide variety such as dirty, paint residue, waste oil, waste plastics, rubber scraps, metal scraps, glass scraps, ceramic scraps and slag, construction waste materials, concrete solidified products, etc. is there. Of the above, dirty, paint residue, waste oil, waste plastics, etc. are hydrocarbons, alcohols, ketones, ethers, fatty acids,
It contains a large proportion of oils and fats (including organic solvents) such as esters. In addition to the above, various types of industrial waste continue to increase year by year, and their treatment has become a major social issue. Currently, landfilling and incineration are the main treatment methods, and the considerable amount of the above Most of the oil-containing waste is incinerated at a high cost.

However, the land that can be landfilled is limited, and the landfilled waste may flow into rivers and the ocean, causing serious environmental problems. There are many problems such as damage to the incinerator due to extremely expensive waste plastic, etc., and difficulty in locating the incinerator due to opposition from local residents. Therefore, various attempts have been made to recycle industrial waste rather than simply treating it as waste, and many of them aim at reuse as alternative fuels in energy-intensive industries such as cement manufacturing. It is a thing. As an alternative fuel or the like, conventionally, a method of removing water contained together with oil, solidifying it into a fuel, or fluidity,
Although a method of appropriately adjusting the oil content and water content of the entire waste into a fuel in slurry has been attempted in consideration of the amount of heat generation and the like, it seems difficult to put into practical use in any case.

[0004]

SUMMARY OF THE INVENTION According to the present invention, industrial waste that has conventionally been disposed of by means such as landfill or incineration is irrespective of the oil and water contents, and
If necessary, including those containing almost no oil and water while atomizing or after atomizing, a plurality of wastes are mixed at an appropriate ratio (need not to be emulsified) to prepare the industry. It is an object to provide a method of reusing as fuel for automobiles.

[0005]

According to the present invention, when a plurality of industrial wastes are soiled, paint residue, etc., they are mixed with each other while being atomized by, for example, a grinder if necessary. After processing, it is appropriately mixed into a fuel, which is used as a fuel for an industrial combustion furnace in which the type and form of the fuel are not so limited, such as a cement burning furnace, and the like. It becomes possible to reuse various types of industrial waste as fuel, etc.

The method for recycling industrial waste according to the first aspect of the present invention comprises mixing a plurality of industrial wastes, then introducing the mixture into a pipe, transferring the mixture through the pipe, and then continuously introducing the mixture into a combustion furnace. When it is discharged and burned, the total amount of oil and water in the mixture obtained by mixing the plurality of industrial wastes is 100
When the weight ratio is set to 11 to 100 parts by weight, the water content is adjusted to 0 to 89 parts by weight, and 20% by weight of the mixture is used.
It is characterized in that the viscosity at 1 ° C. is adjusted to 1 to 50,000 centipoise and the calorific value is adjusted to 610 Kcal / kg or more.

Further, in the industrial waste recycling method of the second invention, a plurality of industrial wastes are put into a pipe connected to a combustion furnace, the inside of the pipe is transferred, and the industrial waste is arranged at a predetermined position. When the mixture is mixed by the mixed means, and the mixture is continuously discharged into a combustion furnace and burned, the total amount of oil and water in the mixture formed by mixing the plurality of industrial wastes is 100% by weight. The oil content is 11 to 100 parts by weight, the water content is 0 to 89 parts by weight, and the viscosity of the mixture at 20 ° C. is 1 to 50000 centipoise.
It is characterized in that the calorific value is adjusted to 610 Kcal / kg or more.

Furthermore, a third invention is a combination of the first and second inventions, wherein a plurality of industrial wastes are mixed by an appropriate method and then introduced into a pipe, and a mixing means provided in the middle of the pipe. It is characterized in that it is further mixed by, and then supplied to the combustion furnace. The fourth invention is the second or third invention.
As the mixing means of the invention, a rotary blade type agitator in a stirring tank provided in the middle of the pipe or a line mixer provided in the middle of the pipe is used. The mixing means is not limited to these, and other means may be used.

Further, the sixth to ninth inventions are characterized by mixing a plurality of industrial wastes including atomized industrial wastes or by mixing a plurality of industrial wastes while performing atomization processing. In addition, the methods of mixing and combustion, the ratio of the amount of oil and water in the mixture, the viscosity of the mixture, and the calorific value correspond to those of the first to fourth inventions, respectively.

In the present invention, the respective industrial wastes are continuously combusted after being “atomized” and “mixed” if necessary, or while being mixed with each other through a pipe and a nozzle provided at the tip thereof. Discharge into the furnace and burn. Therefore, the means for mixing, the conditions, the dispersion state of the mixture, etc. are not a big problem, and the continuously transferred mixture may be dispersed almost uniformly on average, and even if it is partially non-uniform. I do not care. Therefore, it is assumed that the piping becomes a little longer due to the layout around the device and the transfer time to the discharge port after mixing becomes several minutes, for example, 2 to 3 minutes, during which each component of the mixture begins to separate. Does not matter at all. Thus, in the method of the present invention, there is no need to emulsify the mixture and keep it homogeneous for a long time.

The above-mentioned atomization can be carried out, for example, by a grinder, a crusher, a ball mill or the like, and the means therefor is not particularly limited. Further, specific industrial waste may be atomized in advance and then mixed with other industrial waste, or industrial waste to be atomized and other waste may be simultaneously supplied to a grinder or the like to be atomized. You may perform and mixing at the same time. Particularly, if a waste containing a relatively large amount of oil or water is simultaneously supplied for atomization, continuous treatment becomes easy. The particle size of the atomized particles is preferably 3 mm or less, particularly about 1 mm or less, but basically any particle can be passed through a pipe or a nozzle.

In the present invention, the particle size distribution of the finely treated particles or the stability of the mixture does not cause any particular problem, but in the known art, the separation of the components should not occur in consideration of transportation and storage. There are some that require emulsification of the mixture as an important requirement. However, although emulsification can be carried out without using an emulsifier under limited special conditions, water and oil are usually separated at the same time when stirring is stopped. The use of such emulsifiers is essential.

In the emulsification operation using the above-mentioned emulsifier, complicated condition setting such as selection of an appropriate emulsifier, suitable emulsification means, order of adding water and oil, amount to be added, and temperature at the time of emulsification operation are carried out. And operation and procedure are required. The present invention does not require any such troublesome operation and the like, and the method of the present invention is very useful in practice. Furthermore, although various industrial wastes used in the present invention often contain solids, the method of the present invention maintains a stable suspended state even in the case of a mixture containing suspended solids. It is not necessary, and the method of the present invention is extremely practical in this sense as well.

The method of the present invention can be applied to a plurality of wastes selected from a large number of industrial wastes such as wood waste, fiber waste, dusts, etc., in addition to the various industrial wastes described above. The "oil" in the "mixture" consisting of these multiple industrial wastes is "11-
"100 parts by weight" and "moisture" are "0 to 89 parts by weight" (the total amount of oil and water is 100 parts by weight). Within this range, a sufficient calorific value as a fuel can be obtained. In particular, as in the fifth and tenth inventions, if the oil content is in the range of 11 to 60 parts by weight and the water content is in the range of 89 to 40 parts by weight, the viscosity of the resulting mixture is appropriate and sufficient heat generation as fuel is achieved. It is preferable because the amount is obtained. If the oil content exceeds 60 parts by weight, the calorific value becomes excessive, and the refractory material of the furnace may be damaged.

The “viscosity at 20 ° C.” of the above mixture measured by a rotational viscometer is in the range of “1 to 50000 centipoise”, and in the first to third inventions, particularly, as in the fifth invention, 1 to 1000. The range of centipoise is preferable because it can be easily transferred in the pipe. Further, even in the case of containing industrial waste requiring atomization treatment as in the sixth to eighth inventions, the fluidity is sufficient if the upper limit is up to 2000 centipoise as in the tenth invention. Furthermore, the "calorific value" is "610 Kcal /
If it is “kg or more”, it will be sufficiently useful as a fuel. The above-mentioned characteristic values are used when determining the ratio of the oil content and the water content while considering the properties of each industrial waste to be mixed, the analysis value such as the calorific value, or the total amount of the oil content and the water content with respect to the total amount of the mixture. Further, it can be prepared by atomizing or mixing so as to be within the above numerical range.

When the total amount of the mixture is 100% by weight, the total amount of oil and water is preferably 20 to 100% by weight, more preferably 80 to 100% by weight. The above oil content and water function to reduce the viscosity of the entire mixture and improve the fluidity, and if the total amount is less than 20% by weight, the viscosity of the mixture increases and pumping becomes difficult, which is not preferable.

Further, the above-mentioned calorific value is 80% by weight or less with respect to 100% by weight of the mixture, taking into consideration the viscosity and water content of the mixture, powder or crushed material such as solid waste plastics, wood waste, and rubber waste. In addition, it can be prepared by adding fiber waste, paper waste, and the like. At this time, the waste may be appropriately atomized if necessary. The reason for setting the upper limit of the amount of addition to 80% by weight is that the above-mentioned wastes are solids, and therefore, if the amount of addition exceeds 80% by weight, the fluidity of the mixture is extremely lowered. If the calorific value is too high, the refractory or the like in the combustion furnace may be damaged, so it is preferable to set the upper limit to about 10,000 Kcal / kg.

Among the above-mentioned industrial wastes, those having a solid content that needs to be atomized are subjected to other industrial wastes while being atomized by, for example, a grinder or a crusher, or after being atomized. Although it is mixed with an object, a mixer, a pipe, a nozzle and the like used in the present invention do not need to be special ones and ordinary ones can be used as they are, and a combustion furnace in which the mixture is supplied as fuel or the like. Etc. are not particularly limited. In the present invention, it is important to continuously mix and burn a plurality of industrial wastes, and this allows the mixture to be burned without particularly limiting the dispersed state of the mixture. The present invention can also be used for general waste other than industrial waste.
