[0013] Preferably, a water collecting chamber 121 is provided below the water permeable layer, and the water collecting chamber is connected to a drainage pipe 122, wherein the water collecting chamber and the water jacket coexist without interfering with each other, and the drainage pipe outlet is located at the water jacket drainage port or outside the furnace body.

[0014] Preferably, the piston is connected to the air cylinder or hydraulic cylinder 28 .

[0015] Preferably, the water absorption hole and the steam discharge hole are one-way holes. The water absorption hole absorbs water inwards, and the steam discharge hole discharges steam outwards. The water absorption hole and the steam discharge hole can be realized by using one-way honeycomb ceramic material, or multiple one-way valves.

[0016] It should be noted that in this solution, the feed port, blanking plate, water jacket, and other structures and connection methods not described in detail are all prior art, and the structure is the same as the prior art; 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.

[0017] In the present invention, the effective use of hydrogen and oxygen can realize the cogeneration of gas and carbon in wood-based garbage, low energy consumption, high efficiency, zero emission, and turning waste into treasure. The hydrogen and oxygen energy described in the present invention is preferably hydrogen and oxygen mixed energy produced by non-membrane method, with a mixed gas pressure of 0.04MPa-0.08MPa, containing 66.66% hydrogen and 33.33% oxygen. The gas has the characteristics of low calorific value fuel gas combustion and vacuum combustion.

[0018] The functions of each part of the present invention are as follows: drying chamber; honeycomb holes are provided at a specific position of the large-diameter hydraulic cylinder, i.e., the water vapor in the center of the drying chamber is forcibly adsorbed when the piston is lifted; at the same time, the foamed ceramics built on the furnace wall and the downslope absorb the water vapor pushed to the furnace wall by the hot air. This solves the problem of poor carbonization of wood chips due to high water content.

[0019] Carbonization bin: The 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 to solve the problem of carbonization steam reduction.

[0020] 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.

[0021] The carbonization process of the present invention is as follows: Drying bin; after feeding, the flip plate is closed. Wood materials enter the drying bin through the feeding port. Wood materials with high water content enter the hydrogen-oxygen ring direct combustion ignition zone, and the hydrogen-oxygen flame automatically ignites. The needle-type hydrogen-oxygen flame in the drying zone and the wood materials are partially mixed to form a high-heat airflow, which dries the surrounding wood materials. Due to the difference in temperature, water vapor enters the concave honeycomb holes of the central hydraulic cylinder, the furnace wall, and the foamed ceramic wall at the downslope.

[0022] The water vapor enters the steam-water collection tube under the strong adsorption force of the cylinder, and flows into the water seal pool from the bottom. The foamed ceramics at the furnace wall and the first throat downslope adsorb the steam-water, and then flow into the water jacket interlayer, and finally flow out at the bottom of the furnace.

[0023] Gasification bin: After the moisture content of the wood material reaches the standard at a certain temperature, the first throat rotary furnace plate or blanking plate rotates to make the dried wood material flow to the gasification bin, and the thermal cracking zone quickly gasifies and cracks the wood material under the condition of forced mixing of hydrogen and oxygen gas.

[0024] Due to its activation, hydrogen and oxygen mixed gas can rapidly pyrolyze the pyrolysis wood material with hydrogen ions and oxygen ions, which can accelerate the thermal cracking speed and increase the pyrolysis environment temperature to 800-1000 degrees, providing sufficient heat source for carbonization and improving the carbonization quality.

[0025] Carbonization bin: The gasified high-temperature wood material is driven by the vibration and rotation device at the second throat of the furnace body, and the cracked wood chips are filled into the fully enclosed carbonization area at the bottom. The honeycomb holes of the hydraulic cylinder force steam to be ejected from time to time, providing conditions for reduction and ensuring the generation of carbon monoxide and hydrogen gas. At the same time, it also improves the carbonization quality and efficiency, making the average calorific value of charcoal above 7800 kcal.
