Description

A manufacturing method of bamboo-charcoal and a kiln}

The present invention relates to a method of manufacturing and charcoal bamboo charcoal, and more specifically to the bamboo charcoal can increase the production efficiency of the bamboo charcoal can be obtained from the same amount of bamboo charcoal from the same amount compared to the conventional It relates to a manufacturing method and a carbonization apparatus.

In general, the cut wood, which cuts oak trees such as brown oak and oyster oak, into a charcoal furnace (kiln) and is baked at high temperature is called charcoal. It has been reported that it is abundant and rich in minerals.In addition, the demand for air purification, odor and toxic substances purification, preservative effect, anion accumulation and divergence effect, and electromagnetic wave blocking effect have been known. There is a situation.

Therefore, various products using charcoal have been released in recognition of such efficacy, for example, it is used in a variety of construction materials, including furniture materials, from bedding or sauna saunas with charcoal.

On the other hand, recently, in addition to such charcoal, bamboo charcoal made of bamboo as a raw material is in the spotlight, which has about twice the specific surface area of bamboo charcoal and about 10 times the adsorptivity to foreign substances. As well as being known to be good, the interest in bamboo charcoal is increasing as it is known that the anion release, sterilization effect, water vein blocking effect is better.

The bamboo charcoal is generally produced by cutting and processing the selected bamboo to a certain length, and then charging it into a carbonization furnace (kiln) and heating it by directly contacting a flame at a temperature of about 1000 to 1200 ° C. There was a problem that the yield of charcoal produced from the charged bamboo is low.

In other words, when manufacturing bamboo charcoal by direct contact with a high-temperature flame as in the prior art, the amount of charcoal obtained per tonne of bamboo is generally about 150 to 200 kg, which is too small. There was no time or money limit to meet the supply of charcoal according to demand.

Therefore, the present invention is configured to solve the problems as described above, by obtaining a greater amount of bamboo charcoal from the same amount of bamboo to increase the production efficiency of bamboo charcoal, for the recent increase in demand for bamboo charcoal It is an object of the present invention to provide a method of producing bamboo charcoal which can invigorate the market of various products using bamboo charcoal by supplying smoothly.

In addition, an object of the present invention is to provide a carbonization apparatus used in the process of carbonizing bamboo in the process of manufacturing bamboo charcoal.

The present invention to achieve the above object,

In the method of manufacturing bamboo charcoal using bamboo as a raw material,

Cutting and processing bamboo selected from solid wood to a predetermined length;

Drying the bamboo processed as described above to have a water content of 15 to 25%;

Charging the dried bamboo into a carbonization furnace having a sealed condition and carbonizing it by hot air having a temperature of 600 to 800 ° C .;

Cooling the carbonized bamboo to room temperature as described above; can be achieved by providing a method for producing bamboo charcoal comprising a.

Hereinafter, the present invention will be described in more detail.

First, the bamboo is processed to a certain length by cutting, splitting, and arranging the bamboo of the proper size and the appropriate thickness selected from the solid wood. At this time, the cutting of the bamboo is cut to fit the size of the carbonization furnace used, but it is generally preferable to cut to 90 ~ 100cm.

The bamboo cut in this way is split in the longitudinal direction and arranged to the node. The above described means that the node of the bamboo has a molecular structure dense so that even carbonization can not occur during carbonization. Say that.

Bamboo processed to a certain length as described above is dried so that the moisture content of the bamboo 15 to 25% through a predetermined drying device.

This is because if the moisture content of the bamboo has a high carbonization rate and partial carbonization may occur, in particular, the bamboo is bent to a low density inside, that is, a portion containing a lot of moisture during the carbonization process, through the above drying process It can accelerate the carbonization of bamboo and reduce the warpage of bamboo.

Bamboo dried as described above is put in a carbonization apparatus that can maintain the airtightness and carbonized by hot air. At this time, bamboo is charged directly into the carbonization device, but for convenience, bamboo is placed in a carbonization device in a porous box and carbonized.

The temperature of the internal air during the carbonization is preferably maintained at 600 ~ 800 ℃, which is maintained below 600 ℃ carbonization rate is too slow to delay the work time, if the carbonization in the state exceeding 800 ℃ severely This is because carbonized parts are generated and bad char is produced.

When the carbon is heated and carbonized by the high temperature air in the sealed carbonization apparatus as described above, bamboo charcoal of about 300 kg or more per ton of bamboo can be obtained, and thus the yield can be much improved as compared with the prior art.

This is because most of the conventional carbonized by direct contact with the flame 1000 ~ 1200 ℃ the bamboo, the area directly in contact with the flame is carbonized severely to create a part that can not play the role of bamboo charcoal By reducing its production efficiency.

However, in the present invention, since the carbon is evenly carbonized by the hot air without directly contacting the bamboo and the flame, it is possible to prevent the occurrence of defective parts of the bamboo, thereby improving its production efficiency.

Bamboo charcoal is produced by collecting the carbon evenly carbonized in the carbonization furnace as described above, and then cooling it to room temperature in a predetermined cooling apparatus or natural state.

In addition, the present invention provides a carbonization apparatus used in the above-described manufacturing method. More specifically, the present invention is the carbonization of the dried bamboo is not directly contacted by the flame when carbonized, but is heated by hot air to cause carbonization Provide a carbonization device for this purpose.

The carbonization apparatus of the present invention described above,

A wire mesh is installed at a predetermined height at an inner bottom, and a circulation pipe is formed at a side to connect a lower portion of the lower portion of the upper portion and at least a portion where the wire mesh is mounted. The upper body and the discharge pipe is installed on the side;

The upper body and the lower body are coupled while maintaining the sealing, one side is formed with a suction pipe connected to the heater mounted separately, the first perforated plate and the second perforated plate formed with a plurality of through-holes are installed in order with a predetermined space portion The lower body; characterized in that consisting of.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is provided only to assist in understanding the present invention, but the present invention is not limited thereto.

1 is a partially exploded perspective view illustrating the carbonization apparatus of the present invention, and FIG. 2 is a cross-sectional view of the carbonization apparatus of FIG. 1.

First, looking at the upper body 10 in the carbonization apparatus of the present invention, the inner bottom is equipped with a wire mesh 11 for accommodating bamboo, the side of the upper body 10 and the upper end of the upper body 10 A circulation pipe 12 is formed to connect a lower end, and the lower end of the circulation pipe 12 is formed to be located at a lower portion than at least the portion where the wire mesh 11 is mounted, and the lower end of the circulation pipe 12 is formed. A discharge pipe 13 for discharging heated air or smoke generated during carbonization is provided on the same line as the site.

The circulation pipe 12 carbonizes the bamboo charged in the upper body 10 and allows the elevated air to flow into the lower end of the upper body 10 along the circulation pipe 12, and thus into the circulation pipe 12. Since the air introduced from the heated to rise again serves to circulate the air existing in the upper body continuously. At this time, the circulation tube 12 is found that at least one or more may be additionally mounted on both sides according to the size of the upper body (10).

In addition, the discharge pipe 13 may be used in connection with a separate wood vinegar extracting device that can extract wood vinegar from the smoke generated by the carbonization of bamboo.

In addition, it is more effective to install the cooling pipe 30 through which the coolant flows to the upper end of the upper body 10 having the above configuration, which is a carbonization device without moving the carbonized process to a separate cooling device This is because the cooling process can be performed within.

In the case of the lower body 20, the upper body 10 and the lower body is coupled while maintaining the sealing, one side is connected to the heater 25 is mounted separately to heat the temperature of 600 ~ 800 ℃ of the lower body 20 A suction pipe 21 for sucking into the inside is formed, and the first perforated plate 22 and the second perforated plate 23 having a plurality of through holes 24 formed therein are sequentially installed with a predetermined space.

The first perforated plate 22 and the second perforated plate 23 of the lower main body 20 are sufficiently dispersed while the heat sucked by the suction pipe 21 is transferred to the upper main body 10, the upper main body 10 It is to prevent the phenomenon that the bamboo is locally heated by evenly heating the air filled in the).

In this case, the through holes 24 respectively formed in the first and second perforated plates 22 and 23 are formed so as not to correspond to each other, but are staggered, which means that the heat passing through the first perforated plate 22 passes through the second perforated plate ( Before passing through 23, it is sufficiently dispersed in the space formed between the first perforated plate 22 and the second perforated plate 23, and then carbonized the bamboo charged to the upper body 10 via the second perforated plate 23. Bamboo can further reduce the local heating phenomenon.

In such a lower body 20, a furnace having a predetermined size is provided between the heater 25 and the suction pipe 21 so that the heat generated from the heater 25 is sufficiently stored in the furnace, and then the suction pipe 21 Can be sent to the lower body (20).

Looking at the operating relationship of the carbonization device of the present invention having such a configuration, first, the heat generated from the heater 25 is sucked into the lower body 20 along the suction pipe 21 is the first perforated plate 22 and the second Moved to the upper body 10 in a sufficiently dispersed state through the perforated plate 23, the heat transferred from the lower body 20 as described above is the temperature of the air filled in the upper body 10 to a sufficient temperature In this way, the heated air is carbonized by heating the bamboo housed in the wire mesh 11 and then raised to the upper end of the upper body 10, the air thus raised is upper again along the circulation pipe 12 After being moved to the lower end of the main body 10, it is heated again by the heat generated from the lower main body 20 to repeat the cycle of carbonizing the bamboo.

The carbonization device having the above operation relationship is carbonized evenly by high temperature air without directly contacting the bamboo and heat, thereby preventing the occurrence of defective parts of bamboo, so that a larger amount of bamboo is produced from the same amount of bamboo. Bamboo charcoal can be produced, and operating costs can be reduced by circulating internal air without introducing external air.

As described above, the bamboo charcoal manufacturing method of the present invention is made by carbonizing the bamboo by the air having a temperature of 600 ~ 800 ℃ under the carbonization conditions in the carbonization, bamboo generated by contacting the flame directly to the conventional bamboo As the defect rate of charcoal can be reduced, more bamboo charcoal can be produced from the same amount of bamboo, and the carbonization time can be saved by adding a step of drying the water content to 15 to 25% by pretreatment process. In addition, the carbonization effect is to reduce the bending of the bamboo.

In addition, the carbonization apparatus of the present invention allows the charged bamboo to be carbonized by air heated by heat without being in direct contact with heat, thereby improving its production efficiency and by circulating the internal air without inflow of external air. The effect is to reduce operating costs.
