Abstract
Description
Technical Field
[0001] This invention relates to the field of charcoal preparation technology, specifically to a charcoal dry distillation device. Background Technology
[0002] Charcoal is a widely used product in daily life and industrial production. Currently, the main methods for charcoal carbonization include earthen kilns, spontaneous combustion, and dry distillation. While earthen kilns can guarantee charcoal quality, the carbonization time is long, resulting in low production efficiency (generally around 40 days). The carbonization process also produces significant amounts of smoke, with harmful gases in the exhaust being directly released into the atmosphere, severely polluting the environment and failing to meet environmental protection requirements. Most manufacturers use kilns employing the spontaneous combustion method. This method relies on the material itself generating heat to carbonize, essentially an oxygen-deficient combustion process. Its disadvantages include dead zones during carbonization and a low yield. Dry distillation offers a short carbonization time, is smokeless and dust-free, is simple to operate, and guarantees product quality. It achieves a 100% carbonization rate, produces non-crushed charcoal, and has a high appearance quality. Therefore, dry distillation carbonization technology is currently the most suitable for widespread application. However, currently used dry distillation carbonization kilns also have certain shortcomings, mainly low cooling time and efficiency, and the direct release of combustible gases and wood vinegar without separation, impacting the environment and wasting resources.

The outlet of the combustible gas check valve is connected to the combustible gas recovery pipe via a secondary flue. The bottoms of both the gas-liquid separator and the combustible gas check valve are connected to the wood vinegar recovery pipe via collection pipes. Cooling devices are installed outside the main flue, the gas-liquid separator, and the combustible gas check valve.

[0021] A charcoal dry distillation device includes a dry distillation pit 1, a main flue 10, a gas-liquid separator 11, a combustible gas check valve 13, a combustible gas recovery pipe 15, and a wood vinegar recovery pipe 17. The dry distillation pit 1 contains multiple dry distillation tanks 2 for holding wood. The dry distillation pit 1 has heating ports 8 that cooperate with the dry distillation tanks 2. The heating ports 8 are located at the lower part of the dry distillation tanks 2 and are used to house heating devices, such as gas furnaces, for heating the dry distillation tanks 2. Insulating material is filled between the dry distillation pit 1 and the dry distillation tanks 2 to insulate the dry distillation tanks 2 and prevent heat loss. A cover 3 is provided on the top of the dry distillation tanks 2, and a lifting ring 9 is provided on the top of the cover 3 for easy lifting of the cover 3 to fill with wood and remove charcoal.

[0022] A water-sealing groove 4 is provided at the junction of the dry distillation tank 2 and the cover 3. Water placed in the water-sealing groove 4 creates a water seal, preventing air from entering the dry distillation tank 2. A drain pipe 5 connected to the water-sealing groove 4 is provided on the outside of the dry distillation tank 2. A drain valve 6 is installed on the drain pipe 5. After charcoal preparation, opening the drain valve 6 allows the water in the water-sealing groove 4 to be drained. One end of the main flue 10 is connected to the inlet of the gas-liquid separator 11, and the other end of the main flue 10 passes through the cover 3 and connects to the inside of the dry distillation tank 2. The outlet of the gas-liquid separator 11 is connected to the inlet of the combustible gas check valve 13 through the auxiliary flue 12. The outlet of the combustible gas check valve 13 is connected to the combustible gas recovery pipe 15 through the auxiliary flue 14. The bottoms of both the gas-liquid separator 11 and the combustible gas check valve 13 are collected through the collection pipe 16 into the wood vinegar recovery pipe 17. The wood vinegar produced during charcoal dry distillation... The high-temperature gas enters the gas-liquid separator 11 for gas-liquid separation. The separated wood vinegar enters the wood vinegar recovery pipe 17 through the collection pipe 16 for collection. The combustible gas enters the combustible gas check valve 13. The combustible gas contains wood vinegar components, which are cooled by the inner wall of the combustible gas check valve 13, and then enter the wood vinegar recovery pipe 17 through the collection pipe 16 for collection. The combustible gas enters the combustible gas recovery pipe 15 for collection, thus eliminating the impact on the environment. The collected combustible gas and wood vinegar can be reused after recycling, thus preventing resource waste.
[0023] Cooling devices are installed on the outside of the main flue 10, gas-liquid separator 11 and combustible gas check valve 13. The cooling devices are used to cool the main flue 10, gas-liquid separator 11 and combustible gas check valve 13, thereby reducing the cooling time and efficiency. The cooling device includes a water supply pipe 18, a main flue cooling cylinder 19, a gas-liquid separator spray pipe 22, a combustible gas check valve spray pipe 23, a water receiving tray 24, and a return water pipe 25.

The lower part of the main flue cooling cylinder 19 is connected to the water supply pipe 18 through the main flue cooling cylinder inlet pipe 20. The upper part of the main flue cooling cylinder 19 is provided with a flue cooling cylinder drain pipe 21. Cooling water in the water supply pipe 18 enters the main flue cooling cylinder 19 from the main flue cooling cylinder inlet pipe 20 to cool the main flue 10, and then exits from the flue cooling cylinder drain pipe 21. One end of the gas-liquid separator spray pipe 22 is connected to the water supply pipe 18. The other end of the spray pipe 22 is located above the gas-liquid separator 11. The cooling water in the water supply pipe 18 flows through the gas-liquid separator spray pipe 22 to the top of the gas-liquid separator 11 to spray and cool it. One end of the combustible gas check valve spray pipe 23 is connected to the water supply pipe 18, and the other end of the combustible gas check valve spray pipe 23 is located above the combustible gas check valve 13. The cooling water in the water supply pipe 18 flows through the combustible gas check valve spray pipe 23 to the top of the combustible gas check valve 13 to spray and cool it. The water receiving pan 24 is located below the flue cooling cylinder drain pipe 21, the gas-liquid separator 11 and the combustible gas check valve 13. The bottom of the water receiving pan 24 is connected to the return water pipe 25. Water discharged from the flue cooling cylinder drain pipe 21, water cooled by spraying from the gas-liquid separator 11, and water cooled by spraying from the combustible gas check valve 13 flow into the water receiving tray 24 for collection, and then into the return water pipe 25.
