Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous carbonization furnace for continuously carbonizing wood material and a continuous carbonization activation furnace for activating a carbide produced in the furnace to produce activated carbon. Carbonized thinned wood, including forest trees, street trees, and other foliage produced by pruning, sawmills, sawdust, planks, and other woody materials that have been discarded. The present invention relates to a continuous carbonization activation furnace in which a carbide is further activated while maintaining a temperature so that it can be effectively used.

[0002]

BACKGROUND OF THE INVENTION In the field of forestry, there is a strong demand for appropriate treatment or effective use of so-called thinned timber and the foliage produced in pruning of growing trees. As part of the effective use, for example, thinned timber is used for laminated timber and the like. Techniques such as doing so have been proposed. However, these technologies have problems in terms of the total cost associated with production, and do not lead to proper treatment or effective use of bark, foliage, etc., and the bark, foliage, etc. are currently incinerated or left untreated. Therefore, there is no problem from the viewpoint of environmental protection and resource utilization. Also, sawmills, planks, sawmill scraps and the like are generated in large quantities at the sawmill site, but only a very small part of them is used and most of them are incinerated and discarded. Such a situation is the same for wood chip waste generated in a paper mill, a foliage material obtained by pruning a street tree, and the like. It is not an exaggeration to say that these effective uses are urgently needed from the viewpoint of resource measures and environmental measures.

[0003] By the way, carbonization of plant-derived raw materials, such as wood, coconut shell, bamboo, etc., ancient and plant-like coal, and phenolic resin containing oxygen in the molecule, naturally makes it porous. Activated carbon which is made more porous by further activating these carbides is indispensable as an adsorbent in various fields. Activated carbon is produced all over the world, and its production amount now exceeds 1 million tons. Its use and demand for various industrial uses, environmental improvement and the like tend to increase more and more. The method of producing activated carbon is divided into carbonization and activation. In the case of wood-based activated carbon, the carbonization process involves a water content of 15%.
Carbide is about 25% by weight based on 100 wood materials.
About. The activated carbon obtained by further activating this carbide has a weight ratio of about 5 with respect to the wood material 100, and the yield is not high. In the production of activated carbon, carbonization and activation are often separated. That is, under the present circumstances, in many cases, carbonization is performed by a small company and activation is performed by a large company. Even in the case of production at one location, the carbonization process and the activation process are almost always separated. Therefore, heat loss is extremely large. For example, in the case of wood-based activated carbon, about 5 activated carbons are produced with respect to the raw material 100 converted to a water content of 15% as described above. At the time of carbonization, half of the energy of the raw material is converted into gas and released as unused. In the case of coconut shell activated carbon, the yield is increased to about 10% under the same conditions, but about 100 liters of kerosene is required per tonne of activated carbon. In any case, the waste of energy will only cover the eyes.

[0004] On the other hand, in all of the present activated carbons, techniques are concentrated on improving the porosity. However, according to the study of the present inventors, it has been elucidated that there are latent characteristics such as electric and electronic characteristics in addition to the porosity. In other words, it has been empirically recognized that functional ceramics, tourmaline (tourmaline), bincho charcoal, etc. are effective for water reforming and environmental improvement of indoor spaces. Has been attributed to far-infrared radiation in the normal temperature range. However, far-infrared rays in the normal temperature range are extremely small in energy level, and are hardly effective sources. Recent research has confirmed that the substance emits far-infrared as a carrier wave, and a modulated ultra-low frequency of about 1.2 to 1.6 Hertz is emitted from the substance, which is effective. It is considered to be the root. It is presumed that the smaller the vibration frequency, the greater the effect.

On the other hand, the electrical resistivity of mass-produced activated carbon is 0.3 to 3 Ω · cm (volume resistivity).
It has been confirmed by measurement that the lower the resistivity, the lower the transmitted vibration frequency. Therefore, in order to emit a lower vibration frequency from activated carbon, one having a lower electric resistivity is required.

[0006]

FIG. 2 is a partially cutaway sectional view showing a related structure of the first stirring section 2 and the second stirring section 3 provided at the bottom of the carbonization reactor main body 1. The first stirring unit 2 has a hearth 2a having a flat bottom recess and a first stirring body 2b for stirring the raw material stored in the recess. The second stirrer 3 is adjacent to the first stirrer 2 and located at a lower position than the first stirrer 2 so that the first stirrer 2 can receive the carbonized first step carbide transferred by overflowing.

In this embodiment, as the material to be carbonized, “sawdust” is used, and therefore, the stirrer includes the first and second 2
Although a stage configuration is adopted, it is desirable to adopt a configuration in which the number of stages is increased depending on the raw material, and as described above, each stirrer is sequentially disposed at a lower position than the adjacent stirrer. That is, for example, when using papermaking chips, pruning wood chips, or the like as a raw material, the stirring units are configured in a three-stage permutation so that a three-stage carbonization process is performed.

FIG. 3 is a block diagram showing a configuration of a continuous carbonization activation furnace according to an embodiment of the invention according to claims 3 to 6 of the present application. This continuous carbonization activation furnace has a configuration in which an activation furnace is connected to the continuous carbonization furnace shown in FIG.
Since the carbonization furnace body and the like have the same configuration, repeated description will be omitted. In the figure, reference numeral 9 denotes an activation furnace for transferring and activating the second process carbide generated in the second stirring section 3 of the carbonization reactor main body 1, and 15 denotes an activation supplied from the activation furnace 9. This is a cooling unit as a cooling means for carbide.
The cooling section 15 has a screw feeder in which the front portion is indirectly cooled by water cooling in the shaft and the outer peripheral portion, and the rear portion has no direct fountain, so that the product temperature is about 70 degrees Celsius. ing. Although not shown, when the carbonization furnace shown in FIG. 1 is used as a single carbonization furnace, the same cooling means as described above is attached to the product outlet.

The activation furnace 9 is provided in the second part of the carbonization reactor main body 1.
A conveying path 10 for the second process carbide from the stirring section 3, an inclined hearth 11, a blower 12 for supplying air as a means for raising the temperature of the second process carbide transferred to the inclined hearth 11,
It includes means for controlling activation of process carbides and a gas passage 14 connected to the gas combustion furnace 5. The activation control means is a blower 12 as an activation gas supply means, a blower 13a, 13b, and a tilt, which freely control and supply to the activation furnace 9 a type and an amount to be selected from oxygen, carbon dioxide gas and steam as an activation gas. It is composed of a vibrating means 16 of the hearth 11 and a variable inclination means of the inclined hearth 11,
As the activation gas, the combustion exhaust gas in the gas combustion furnace 5 is used.

The operation will be described based on the above configuration. 1 and 2, first, a kerosene bar as an ignition means is used.
Igniting the feeder hopper 4 by operating the horizontal screw feeder 4b as the first transfer means and the vertical screw feeder 4c as the second transfer means.
The raw material stored in a is sent to the hearth 2a of the first stirring section 2 from the bottom. When the raw material reaches a predetermined amount, the raw material supply is stopped once, a pilot flame is fed into the raw material of the first stirring section 2 through an ignition opening / closing hole provided on a side surface of the carbonization reactor main body 1, and a first blower 6a is used. A small amount of air is sent from the bottom to confirm ignition and close the opening / closing hole. Next, the supply of the raw material is started at a relatively low speed, the speed is gradually increased, and the amount of supplied air is also increased. Next, at the stage where the substantially carbonized raw material is overflowed into the second stirring section 3, the blowing from the second blower 6b is started. About 30 minutes after the start of the blowing, the carbonization reaction in the carbonization reactor main body 1 is in a steady state. The kerosene burner 8 is stopped when the temperature in the gas combustion furnace 5 reaches about 900 ° C. and the raw material of the first stirring section 2 is ignited. Since the vertical feed screw feeder-4c and the agitator 2b are coaxial, the agitator 2b also rotates in accordance with the rotation of the vertical feed screw feeder-4c, and the raw materials sequentially transferred are transferred to the furnace floor 2b.
a. In addition, raw material hopper-4a
The raw materials stored in the plant are made from thinned wood in the form of chips or granules and have a water content of 15% or less.
The raw material is not only such thinned wood, but also wood chips, such as sawdust, planing scrap, sawmill scraps, etc. generated at the milling site, wood chip scraps generated at paper mills, and foliage, such as pruned street trees. If you can use everything. However,
The degree of drying is desirably 15% or less of water content. Even if the value slightly exceeds this value (up to about 25% of water content), carbonization is possible, but it is necessary to set two or more stirring units. As a result, the coal capture rate decreases as a whole. Therefore, it is more advantageous in terms of total cost to recover the exhaust heat in the gas combustion furnace 5 and use the raw material after drying it to a water content of about 15%.

In the above, in the first stirring section 2, the operation of the first blower 6a is controlled so that the entire temperature is about 300 to 350 ° C., and the slit or nozzle at the bottom of the air chamber 2c and the hearth 2a is controlled. To feed air through. At this stage, most of the raw material has reached the ignition temperature, a carbonization gas is generated, a part of which starts burning, and the first carbonization step proceeds for the raw material. The first produced by this process for several minutes
The carbonized carbide is overflowed from the upper part of the hearth 2a by the rotation of the stirrer 2b, and the second carbide at the lower position adjacent to the hearth 2a.
It falls on the hearth 3a of the stirring part 3, and the hearth 3
The second carbonization step is performed while being stirred in a. Also in the second carbonization step, the operation of the second blower 6b is controlled to supply a predetermined amount of air to the second stirring section 3 through the air chamber 3c and the slit or nozzle at the bottom of the hearth 3a, and the temperature is adjusted. . The second carbonization step is about 3 minutes. Upon completion of the second carbonization step, a desired carbide is generated, and is overflown from the upper part of the hearth 3a with the rotation of the stirrer 3b to be out of the carbonization reactor main body 1. It is discharged and cooled by cooling means and used as carbide. In the above description, the completion of the first carbonization step, that is, the overflow of the first step carbide from the first stirring section 2
The timing of (1) is adjusted according to the result of detection by the temperature sensor, and the temperature is about 300 to 350 degrees Celsius as described above. The same applies to the second carbonization step in the second stirring section 3, and when the second step carbide reaches about 400 to 500 degrees Celsius, the second stirring section 3 overflows and the carbonization step ends.

The heat history temperature of the carbide according to the embodiment produced through the above steps was 400 to 450 ° C., and the remaining amount of volatiles was 23 to 30%. In the above process, the temperature of the carbonization gas is 500 to 500
The air supply amount by the blower is controlled so as to be about 550 ° C. The reason is that, when a small amount of an organic chlorine compound or the like is mixed in the carbonized raw material, it is converted into hydrogen chloride (HCL) as much as possible, and the generation of dioxin-derived substances such as hexachlorobenzene is prevented. That's why. There is a reputation that carbon dioxide does not generate dioxins in carbonization, but according to some research data, generation of dioxins is
It has been reported that the temperature is significantly related to the carbonization temperature (A-
Ring et al., 1978).

The carbide obtained in the above step has pores formed naturally during carbonization, and can be used as it is for soil improvement and other various uses. Activated carbon can be obtained by forming fine holes. This activation operation is performed in the activation furnace 11 shown in FIG. That is, the overflow from the second stirring section 3 is performed.
The obtained second step carbide has a temperature of about 400 to 450 ° C. and a volatile content of about 25% on average, and is dropped and transferred to the inclined hearth 11 via the transfer path 10 without being sent to the cooling means. A large number of slits are formed in the bottom of the inclined hearth 11, and air is blown from two places by a third blower 12 as a temperature raising means through these slits or nozzles. By the supply of this air, a relatively large amount of volatile matter remaining in the second carbonization step burns, and the temperature rapidly burns to reach 1000 ° C. or more. The second carbonization process product in the inclined hearth 11 undergoes an activation step while being controlled by the activation control means while moving the hearth by the inclination of the inclined hearth 11 set by the inclination varying means and the vibration means 16. Will be. That is, as described above, the activation control means supplies the activation furnace 9 with a blower 12 and a blower 13a as activation gas supply means for freely controlling the type and amount to be selected from oxygen, carbon dioxide gas and water vapor as activation gas. ,
13b, the vibrating means 16 of the inclined hearth 11 and the variable inclination means of the inclined hearth 11; selection of the type of the activation gas, control of the amount, adjustment of the hearth frequency (by increasing or decreasing the frequency). The activation condition can be adjusted by adjusting the inclination of the hearth (the residence time of the second carbonization step can be increased or decreased by increasing or decreasing the inclination angle). It will be controlled freely. As the activation reaction, there are steam activation, carbon dioxide activation, and oxygen activation as is well known. In the present invention, a desired activation operation can be performed by controlling the amounts of steam, carbon dioxide, and oxygen. Among the activation gases, carbon dioxide gas is obtained by cooling the exhaust gas (about 1200 degrees Celsius) generated in the gas combustion furnace 5 by water cooling.
The one cooled to 0 degrees is used. As the steam, a steam obtained by collecting the steam generated during the water cooling is used.

The surface area of pores of ordinary charcoal is 200 to 40.
It is often in the range of 0 m ² / g. The operation of imparting further porosity to such charcoal is an activation operation. Generally, the above-mentioned surface area is 800 m ² / g or more and is often called activated carbon. There are various types of pores in this activated carbon. Macropores having a pore diameter of 500 Å or more are mesopores and pores having a pore diameter of 500 to 20 Å are mesopores.
Those having 0 to 8 angstroms may be called micropores, and those having 8 angstroms or less may be called submicropores. In the activated carbon industry today, the production of activated carbon having micropores having an average pore diameter of 8 to 20 has become mainstream. However, this expression is not accurate,
Strictly speaking, it should be said that the conventional activation method produces activated carbon having micropores. The reason is that, in the conventional method, the selection setting of the activation gas, the control of the gas amount, the temperature management, the control of the activation time, and the like could not be performed in the activation operation. However, it has now been found that the function of activated carbon varies depending on the average pore diameter, high heat history and the like. That is, for example, for lithium batteries and dioxin adsorption, the average pore diameter is 500 to 2
Activated carbon having a mesopore of 0 Å is effective. According to the present invention, it is possible to manufacture activated carbon suitable for use by freely controlling the activation conditions.

As described above, as the activated carbon has a higher temperature history, a smaller electric resistivity can be obtained. However, in the prior art, the temperature history is around 900 degrees Celsius, and a cooled carbide is used. Therefore, enormous energy is required. On the other hand, in the present invention, since the carbide is continuously transferred from the carbonization furnace to the activation furnace while maintaining the temperature of the carbide (400 to 550 degrees Celsius), 1000 degrees or more can be easily obtained simply by supplying oxygen to the carbide. High temperature history can be realized. That is, for example, it is possible to obtain activated carbon having electric and electronic characteristics having an electric resistivity of 0.1 Ω · cm or less, a heat history temperature of 1,100 degrees (Celsius) or more, and a transmission frequency of 1 Hertz or less. In addition, the carbonization process and the activation process can be automated by computer control, and if it is installed near the place where thinning residue is generated, it can be operated by hand with little maintenance and management, so thinning was difficult to use effectively. High value-added products can be obtained at low cost from residual materials.

[0024]

As described above, according to the present invention, carbide and activated carbon having desired functions adapted to the demand while saving energy by controlling the temperature in the carbonization step and freely controlling the activation conditions in the activation step. Can be obtained in high yield. In addition, since the activation of the carbide is continuously performed while maintaining the temperature in the carbonization step, a high temperature history can be easily realized, but there is no waste of energy. As a raw material, most of the woody material, such as pruning residue in forest land, can be used, which greatly contributes to the effective use of resources.
