Description

Overheated stem using manufacturing equipment of wood drying carbonization

The present invention relates to a wood drying apparatus using superheated steam, and more particularly, to prevent deformation and cracking of wood due to changes in humidity as the wood is dried by superheated steam, and does not use chemical protection members. The present invention relates to a wood drying apparatus using superheated steam, which can obtain eco-friendly wood materials and reduce the costs incurred when drying wood, as well as improve the economics by mass-producing high quality wood.

In general, the drying of the wood reduces the moisture content, thus reducing the transportation cost and storing it safely, preventing damage caused by shrinkage of the wood, increasing the strength of the wood, increasing the nail or screw holding capacity, improving the adhesion and paintability, Increased electrical insulation, improved thermal insulation, ease of medicinal herb leaf, preventing the charge, discoloration and corruption can be obtained.

There are two methods of drying wood such as natural drying and artificial drying. Due to the fact that natural dried wood has no deformation and good properties, the drying period is too long (2 ~ 3 years) Artificial drying is performed mainly by supplying a heat source and drying.

Artificial drying method uses the artificially set drying conditions to rapidly dry without damaging the wood to low moisture content which cannot be reached by natural drying. There are various kinds of drying, combustion gas drying, vacuum drying, chemical drying, high frequency drying, but hot air drying is mainly used.

The hot-drying method is subdivided according to the method of making heat, the circulation of the heat and the progress of the drying operation.However, when the drying target wood is loaded and dried, the combustion chamber supplying the heat is installed to protrude from the center of the carrier. Is directly in contact with the radiant furnace of the combustion chamber, there is a problem in that a large amount of the contact portion is carbonized and disposed of.

In addition, since the exhaust communication exhausting hot air is penetrated in the upper part of the drying chamber, high temperature heat is easily released, thereby increasing energy consumption for drying, and in particular, heat is easily released, so that uniform temperature, which is the most important element of wood drying, is uniform. There is a problem that it is difficult to maintain.

In addition, since there is no means for supplying a separate moisture inside the drying chamber, it is impossible to control the moisture contained in the wood, so that the deformation of the wood is severely generated, and it is impossible to dry it with the water-containing wood required by the consumer. There is this.

Looking at the prior art, there has been devised a method of drying wood, which is registered in Korean Patent No. 10-0577218, in which a wood-based fuel such as waste wood is put in a combustion chamber installed at a lower portion of a combustion gas generating furnace to combust the wood-based fuel. A method of drying wood, comprising: heating the wood by the combustion gas by introducing hot combustion gas generated at the time of combustion into an upper portion of a drying chamber accommodating the timber, wherein the combustion gas contained in the drying chamber. Is maintained at a high concentration in the range of 60 to 95 (volume)% and at a high value in the combustion gas to maintain the pressure in the drying chamber at a high pressure in the range of 1.5 to 5 atm. Since the pressure of the atmosphere inside the drying chamber is maintained at a high value, it is expected that the wood can be dried efficiently in a short time.

However, in the case of the prior art, not only has a problem that cracks are generated in the wood that is dried by too high pressure, but also it is impossible to use as a building material due to cracks, and in order to use it as a building material, the wood must be reworked and trimmed. There is a problem.

In addition, there is a problem that causes pollution of the user or the land as the chemical preservation treatment to prevent the decay of the dried wood.

On the other hand, the carbide obtained by burning the wood waste is carbonized and used in the agricultural soil of the plastic house, or in the seed germination box, it is used to promote the germination of seeds by mixing soil and carbides. Carbide charcoal powder is widely used to promote the growth and development of plants planted in flower beds.

Such carbides are carbonized in the waste wood by driving the screw stirrer in the elliptical carbonization furnace outside the rotary shaft to drive the carbides together with agitation, and exhaust the heat generated during the carbonization. It is configured to exhaust the reburner.

As a result, the carbonization efficiency is low, and the guide plate is composed of a hollow plate and a round plate in the carbonization barrel. Therefore, the transport of carbides is not smooth and the ashes are produced more than the production of carbides. Since the screw stirrer is installed in the lower part of the carbonization furnace, there is an urgent problem in obtaining an efficient carbide according to the disadvantage of forming a complicated structure and a large power consumption defect.

In particular, in the case of the wood vinegar generated during the drying process because the oil and rosin are included there is a problem that causes another contamination.
