specific Embodiment approach 1

[0022] Specific implementation mode 1: A kind of manufacturing method of the environment-friendly preservative wood with biomass gas as the heating medium described in this implementation mode is specifically carried out according to the following steps:

[0023] 1. Select flat wood and place it in the air to dry to obtain air-dried wood;

[0024] 2. Open the door of the heat treatment kiln, and stack the air-dried wood on the support frame of the heat treatment chamber in the heat treatment kiln from bottom to top, so that there is a certain distance between the wood;

[0025] 3. A certain amount of biomass material is scattered and placed in the combustion chamber of the heat treatment kiln;

[0026] 4. Close the heat treatment kiln door, open the air intake and exhaust holes of the heat treatment kiln;

[0027] 5. Ignite the biomass material placed in the combustion chamber, so that the hot air flow generated by the combustion of the biomass material enters the heat treatm...

specific Embodiment approach 2

[0038] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the distance between the woods in step 2 is 5-15 cm. This distance can ensure the smooth ventilation between the woods and is conducive to uniform heating. It can ensure that the most wood can be placed in the heat treatment room, which is beneficial to maximize the use of space. This spacing can be fine-tuned according to the size and quantity of wood, so as to achieve the best anti-corrosion effect. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0039] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step six, the heating rate in the heat treatment chamber is controlled at 20°C / h, combined with steam spraying, this heating rate can ensure that the wood does not heat up during the heating process. Cracking and deformation can shorten the heating time to a certain extent. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention provides an environmentally-friendly antiseptic wood manufacturing method with biomass gas as a heating medium, and relates to the antiseptic wood manufacturing method. The method mainly solves the problems that an existing wood corrosion prevention method is harmful to the environment, and a traditional heat processing corrosion prevention method contaminates the environment and is higher in cost. The method includes the steps that 1, air seasoning is conducted on wood; 2, the dried wood is placed in a heat processing chamber; 3, biomass materials are placed in a combustor; 4, a heat processing kiln door is closed, an air inlet hole and an air outlet hole are opened; 5, the biomass materials are ignited; 6, the temperature rises, and steam is sprayed; 7, when the temperature rises and reaches the designated temperature, ternary mixed gas is kept in a kiln to make the biomass materials to be burned weakly; 8, heat preservation is conducted for 2.5 hours to 3.5 hours; 9, the temperature drops, steam is sprayed, and hydrating is conducted; 10, when the difference between the indoor temperature and the outdoor temperature of the heat processing chamber ranges from 25 DEG C to 35 DEG C, the wood is taken out, air seasoning is conducted on the wood, and the obtained dried wood is the environmentally-friendly antiseptic wood. According to the method, the biomass gas is adopted as the heating medium, no chemical preservative is added, the manufactured antiseptic wood is environmentally friendly, and environment protection is facilitated.

Description

technical field [0001] The invention relates to a method for manufacturing anti-corrosion wood, in particular to a method for manufacturing anti-corrosion wood through ternary mixed gas. Background technique [0002] Wood is a natural organic complex, and its cell wall components and various carbohydrates contained in the cell cavity are susceptible to various wood-rot fungi under certain conditions, causing wood decay. The antiseptic treatment of wood can effectively improve the antiseptic performance of wood. At present, the main method in China is to use various types of preservatives to treat wood to improve the corrosion resistance of wood. However, the composition of preservatives will cause a certain degree of corrosion. Environmental pollution, endangering humans and animals, the United States and the European Union are formulating some regulations to limit the use of chemical preservatives to treat wood in some occasions. Therefore, there is a broad space for devel...
