Wood carbonizing device

Abstract

The invention discloses a wood carbonizing device, which comprises a carbonizing box, a box door, an air-permeable wood accommodating clapboard, one-way humidity-discharging holes, an inverted-M-shaped hot air discharge pipe, a fuel gas burner, a fuel gas pipe, a combustion chamber, a hot air fan and hot air circulating pipes, wherein the clapboard is arranged on the lower part of the carbonizing box, and is used for partitioning the carbonizing box into a wood accommodating region and a heating region; a plurality of one-way humidity-discharging holes are uniformly distributed in the top wall of the carbonizing box; the combustion chamber is an enclosed container; the hot air discharge pipe is arranged in the heating region; the hot air inlet of the hot air discharge pipe hermetically passes through a carbonizing box wall and a combustion chamber wall, and extends into the combustion chamber; the fuel gas pipe and the burner hermetically pass through the combustion chamber wall, and extend into the combustion chamber; the air inlet end of the hot air fan is connected with a hot air circulating pipe; the other end of the circulating pipe hermetically passes through the top box wall of the carbonizing box, and extends into the box; the air outlet end of the hot air fan is connected with another hot air circulating pipe; and the other end of the circulating pipe is communicated with the combustion chamber. Due to the adoption of the device, excellent effects of preventing the propagation of molds on wood and ensuring the appearance quality of carbonized wood are achieved.

Description

technical field [0001] The invention relates to the technical field of wood processing and treatment, in particular to a wood carbonization device. Background technique [0002] Deep carbonized wood is wood treated by high-temperature carbonization technology at about 200 degrees. Because its nutrients are destroyed, it has good anti-corrosion and insect-proof functions. In addition, because its water-absorbing functional group hemicellulose is reorganized, its physical properties are also improved. . Although deep carbonized wood has anti-corrosion and insect-proof properties, it does not contain any harmful substances, which not only improves the service life, but also does not have any negative impact on humans, animals and the environment during the production and use process and after use. A real green product. Deep carbonized wood has nearly ten years of experience in Europe. It is the main replacement product after CCA anti-corrosion wood is banned. Deep carbonized...

Problems solved by technology

[0003] The current wood carbonization technology uses high-temperature water vapor as the direct heating medium and protection medium. For some special woods with high moisture content, such as eucalyptus and birch, in the drying stage before carbonization, due to the action of water vapor and oxygen, in the wood A large number of mold spots will be produced in the wood, which will affect the appearance quality of the wood after carbonization
