[0016] The following are specific embodiments of the present utility model and in combination with the drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0017] Such as Figures 1-3As shown in the figure, a carbonization heat recycling device of the present utility model includes a base 1, a carbonization furnace body 2, a flue gas tank 6 and a heat preservation water tank 5. The top end of the base 1 is fixedly installed with the carbonization furnace body 2. The smoke outlet end of the carbonization furnace body 2 is connected to the bottom of the flue gas tank 6 through a pipeline. The flue gas tank 6 is connected to the heat preservation water tank 5 through a connecting water pipe 8. The flue gas tank 6 is composed of an inner tank body 12 and an outer tank body 13. The inner tank body 12 is sleeved and connected inside the outer tank body 13. A plurality of heat conduction components are equidistantly arranged at intervals on the inner wall of the inner tank body 12. Air pumps 10 are fixedly arranged at the tops of both sides of the outer wall of the inner tank body 12. The two air pumps 10 are communicated with the bottom of the inner tank body 12 through air guide pipes 11.

[0018] Specifically, the flue gas generated during the carbonization process of the carbonization furnace body 2 flows into the flue gas tank 6. The heat conduction components arranged in the flue gas tank 6 recover the heat of the flue gas, and the recovered heat is used for preheating the materials before carbonization, effectively improving the utilization of resources, reducing the energy consumption during the carbonization process, and saving costs.

[0019] As Figure 1 、 Figure 2 and Figure 3 shown in the figure, a carbonization heat recycling device of the present utility model, a smoke exhaust pipe 7 is fixedly installed at the top end of the inner tank body 12. The smoke exhaust pipe 7 is inserted and connected with the outer tank body 13. A first electromagnetic valve 9 is fixedly installed inside the smoke exhaust pipe 7.

[0020] Second electromagnetic valves 16 are fixedly installed inside both air guide pipes 11.

[0021] The heat conduction components include heat conduction plates 14 and water circulation pipes 15. A plurality of heat conduction plates 14 are fixedly installed at equal intervals with the inner tank body 12. Water circulation pipes 15 are fixedly installed inside the plurality of heat conduction plates 14. The water circulation pipes 15 are communicated with the connecting water pipe 8 through a multi-way connection.

[0022] Specifically, the heat conduction components can recover the waste heat in the flue gas.

[0023] A temperature sensor is fixedly installed at the top end inside the inner tank body 12. The temperature sensor is electrically connected to an external PLC controller.

[0024] Specifically, through the temperature sensor, the temperature of the flue gas inside the inner tank body 12 can be monitored.

[0025] A heat preservation protective cover 3 is fixedly installed at the top end of the base 1.

[0026] Specifically, the hot water inside the heat preservation water tank 5 is circulated through the preheating flow channel 17 by the circulating pump 4, which can preheat the carbonized materials and reduce the energy loss of the carbonized materials.

[0027] For specific implementation, when using this recycling device, first turn on the power supply. The heat generated by the operation of the carbonization furnace body 2 flows into the flue gas tank 6. Then, the water is pumped through the connecting water pipe 8 into the internal water circulation pipe 15 of the corresponding heat conduction plate 14 by the water pump on the side of the heat preservation water tank 5. Through the circulation of the water circulation pipe 15, the heat of the flue gas in the flue gas tank 6 can be recovered. During the process of the flue gas moving from bottom to top, multiple heat conduction plates 14 are distributed at intervals, improving the heat recovery effect. At the same time, the temperature sensor installed at the top of the inner tank body 12 detects the temperature of the flue gas in real time. When the heat recovery of the flue gas is poor, the second solenoid valve 16 is opened and the first solenoid valve 9 is closed through the external PLC controller, so that the flue gas is pumped into the inner tank body 12 for secondary recovery;

[0028] When the recovered heat needs to be utilized, turn off the water pump and turn on the circulating pump 4. The hot water is pumped into the internal preheating flow channel 17 by the circulating pump 4. Through the water circulation of the preheating flow channel 17, the carbonized materials can be preheated, reducing the energy loss during the carbonization process.
