[0021] An annular hydrogen and oxygen pipeline 11 is provided in the drying chamber, on which a plurality of hydrogen and oxygen burners and ignition needles are provided, and the annular hydrogen and oxygen pipeline is connected to an external hydrogen and oxygen generator;

[0022] The cross-section of the first throat is a horizontal V-shape. A permeable layer 12 is provided on the upper slope of the first throat, and a hydrogen and oxygen nozzle 13 is provided on the lower slope. The permeable layer is a one-way permeable foamed ceramic, fixed to the furnace body by masonry or clamping. The permeable layer is connected to a drainage pipe, which is located in the water jacket and has an outlet located at the drain port of the water jacket or directly through the water jacket (furnace wall) for discharge. A carbon discharge turntable 14 and a carbon discharge port 15 are provided below the carbonization bin.

[0023] The steam-water collecting cylinder 2 includes a main cylinder 21 and an auxiliary cylinder 22. A piston 23 is provided inside the main cylinder, a water suction hole 24 is provided on the cylinder wall of the main cylinder, a one-way valve 25 is provided on the upper part of the auxiliary cylinder, a steam discharge hole 26 is provided on the cylinder wall of the auxiliary cylinder, and a drain port 27 is provided at the bottom of the auxiliary cylinder, which corresponds to the water seal 16 below the furnace body.

[0024] Preferably, Figure 4 As shown, a water collecting chamber 121 is provided below the permeable layer, and the water collecting chamber is connected to a drainage pipe 122, wherein the water collecting chamber and the water jacket coexist and do not interfere with each other, and the drainage pipe outlet is located at the water jacket drainage port or outside the furnace body.

[0025] Preferably, the piston is connected to the air cylinder or hydraulic cylinder 28 .

[0026] Preferably, the water intake hole and steam discharge hole are one-way holes. The water intake hole absorbs water inward, and the steam discharge hole discharges steam outward. The water intake hole and steam discharge hole can be made of one-way honeycomb ceramic material or multiple one-way valves.

[0027] It should be noted that in this solution, the feeding port, blanking plate, water jacket, and other structures and connection methods not described in detail are all existing technologies, and the structure is the same as the existing technology; the unidirectional honeycomb ceramic material used for the unidirectional water absorption hole and steam discharge hole is an existing product, and the specific structure will not be repeated.

[0028] This utility model effectively utilizes hydrogen and oxygen energy to achieve gas-charcoal cogeneration, resulting in low energy consumption, high efficiency, and zero emissions, transforming waste into valuable resources. The hydrogen and oxygen energy described in this utility model is preferably a hydrogen-oxygen mixed energy produced by a non-membrane method, with a mixed gas pressure of 0.04 MPa to 0.08 MPa and containing 66.66% hydrogen and 33.33% oxygen. This gas exhibits low calorific value combustion-supporting properties and vacuum combustion.

[0029] In this utility model:

[0030] The drying chamber features honeycomb holes at specific locations within the large-diameter hydraulic cylinder, also known as the water-vapor collection cylinder. These holes forcefully absorb water vapor from the center of the drying chamber when the piston is lifted. Simultaneously, the foamed ceramics built into the furnace walls and downslope absorb the water vapor pushed toward the furnace walls by the hot air, solving the problem of poor carbonization due to high moisture content in wood chips.

[0031] Carbonization bin: A small-diameter hydraulic cylinder is provided with conical honeycomb holes at specific positions. When the cylinder is pushed downward, part of the water vapor in the drying bin is forced out, thus solving the problem of steam-water reduction for carbonization.

[0032] The remaining steam and water flow into the water seal surface at the bottom of the carbonization bin from the end of the hydraulic cylinder.

[0033] The carbonization process of the present utility model is as follows:

[0034] After loading, the rotating plate closes. Wood material enters the drying chamber through the loading port. High-moisture wood material enters the oxyhydrogen ring direct combustion ignition zone, where the oxyhydrogen flame automatically ignites. In the drying zone, the needle-shaped oxyhydrogen flame mixes with the wood material, creating a high-heat airflow that dries the surrounding wood material. Due to the temperature difference, water vapor enters the concave honeycomb holes in the central hydraulic cylinder, the furnace walls, and the foamed ceramic wall at the downslope.

[0035] The strong adsorption force of the cylinder causes the water vapor to enter the steam-water collection tube and flow into the water seal pool from the bottom. The foamed ceramics at the furnace wall and the downslope of the first throat absorb the steam and water, then flow into the water jacket interlayer and finally flow out at the bottom of the furnace.

[0036] Gasification bin: After the moisture content of the wood material reaches the standard at a certain temperature, the first throat rotary furnace disc or blanking plate rotates to make the dried wood material flow to the gasification bin. The thermal cracking zone quickly gasifies and cracks the wood material under the condition of forced mixing of hydrogen and oxygen gas.

[0037] Due to its activation, hydrogen and oxygen mixed gas can rapidly pyrolyze wood materials, accelerate the thermal cracking rate, and increase the pyrolysis temperature to 800-1000 degrees. It provides sufficient heat source for carbonization and improves the carbonization quality.

[0038] In the carbonization chamber, the gasified, high-temperature wood material is driven by a vibrating rotating device at the second throat of the furnace, which then feeds the cracked wood chips into the fully enclosed carbonization zone at the bottom. Honeycomb holes in the hydraulic cylinder periodically force steam to flow, creating conditions for reduction and ensuring the generation of carbon monoxide and hydrogen fuel gases. This also improves carbonization quality and efficiency, resulting in an average calorific value of charcoal exceeding 7,800 kcal.
