DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] The embodiment of the present invention uses a high-temperature carbonization furnace to solve the problem that the firewood sticks carry about 8% moisture when entering the carbonization furnace, which is the enemy of carbonization, and the machine-made firewood sticks are very easy to be damp, and the moisture in the firewood sticks seriously affects the carbonization quality of the firewood sticks.

[0037] In order to solve the above technical problems, the overall concept of the present invention is as follows: a dehumidification unit 6 is arranged outside the furnace body 1, a power unit 7 is arranged between the dehumidification unit 6 and the furnace body 1, the power unit 7 is connected to the furnace body 1, and the flue gas is introduced into the power unit 7, so that the power unit 7 provides power for the dehumidification unit 6, thereby achieving the effect of the dehumidification unit 6 on dehumidifying the firewood sticks before carbonization, so as to reduce the influence of the moisture carried by the firewood sticks when entering the carbonization furnace on the carbonization quality of the firewood sticks.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] The present invention provides a high-temperature carbonization furnace, comprising a furnace body 1, a furnace cover 2 is provided on one side of the furnace body 1, a locking clip 3 is provided on the furnace body 1, a heater 4 is provided inside the furnace body 1, a purifier 5 is provided outside the furnace body 1, and further comprising:

[0040] A dehumidification unit 6, which is located between the furnace body 1 and the purifier 5 and is used to dehumidify the damp firewood before carbonization;

[0041] The power unit 7 is located between the dehumidification unit 6 and the furnace body 1 to provide power for the dehumidification unit 6 .

[0042] Firewood sticks are widely used as a common carbonized material. Compared with the carbonization of logs, firewood sticks have regular shapes and are not easy to deform after carbonization. However, firewood sticks contain about 8% moisture when entering the carbonization furnace. This moisture is the enemy of carbonization, and machine-made firewood sticks are very susceptible to moisture. The moisture in the firewood sticks seriously affects the carbonization quality of the firewood sticks. In the prior art, the staff often put the firewood sticks into the carbonization furnace for two to three hours of drying. However, the firewood sticks will produce water vapor when being dried, and the water vapor still has a certain effect on the carbonization of the firewood sticks.

[0043] Therefore, the present invention is provided with a dehumidification unit 6 outside the furnace body 1. Before opening the furnace cover 2 through the locking clip 3 on the furnace body 1 to send the next batch of firewood sticks into the carbonization furnace for carbonization, the staff can first use the dehumidification unit 6 to dehumidify the firewood sticks. A power unit 7 is arranged between the dehumidification unit 6 and the furnace body 1. The power unit 7 is connected to the furnace body 1. Flue gas is generated in the process of carbonization of the firewood sticks. The flue gas is introduced into the power unit 7 so that the power unit 7 provides power for the dehumidification unit 6. Then the flue gas enters the dehumidification unit 6 through the power unit 7, so that the dehumidification unit 6 can better dehumidify the firewood sticks before carbonization, so as to reduce the influence of moisture on the carbonization quality of the firewood sticks when the firewood sticks enter the carbonization furnace. Then the flue gas enters the purifier 5 from the dehumidification unit 6 to purify the flue gas. The purified flue gas enters the heater 4 through a pipeline to heat the carbonization furnace, thereby realizing the secondary utilization of the flue gas.

[0044] As a specific embodiment of the present invention, the dehumidification unit 6 includes:

[0045] The first housing 61 is located at a side close to the purifier 5;

[0046] A dehumidification cylinder 62, which is rotatably connected to the first housing 61 to remove moisture from the damp firewood sticks;

[0047] The heating chamber 63 is located in the first shell 61 and provides a heat source for the dehumidification cylinder 62 .

[0048] As a specific embodiment of the present invention, the power unit 7 includes:

[0049] The second housing 71 is disposed on one side of the first housing 61 and is in communication with the first housing 61;

[0050] A first rotating shaft 72, wherein the first rotating shaft 72 is located in the second housing 71, and one end of the first rotating shaft 72 is connected to the dehumidification cylinder 62;

[0051] A fixing frame 73, wherein the fixing frame 73 is disposed in the second housing 71 and is used to fix the rotating shaft;

[0052] The fan 74 is disposed on the first rotating shaft 72 .

[0053] The present invention provides a first shell 61 on one side close to the purifier 5, a dehumidification cylinder 62 is rotatably connected in the first shell 61, a heating chamber 63 is provided in the first shell 61, a second shell 71 is fixedly connected to one side of the first shell 61, the second shell 71 is communicated with the heating chamber 63 of the first shell 61, a first rotating shaft 72 is rotatably connected in the second shell 71 through a fixing frame 73, a fan 74 is fixedly connected to one end of the first rotating shaft 72, and the other end of the first rotating shaft 72 is fixedly connected to the dehumidification cylinder 62;

[0054] The staff first puts the damp firewood into the dehumidification cylinder 62, and then introduces the smoke generated during the carbonization of the firewood into the second shell 71. Since the carbonized firewood is in a sealed space, a large amount of smoke is generated during the carbonization of the firewood, and a certain air pressure is generated in the relatively sealed space. Figure 2As shown, an overflow valve is provided at the outlet of the smoke flow, that is, at the connection point between the air guide pipe 13 and the No. 1 air guide hole 121. When in use, the pressure value of the overflow valve can be adjusted according to the number of firewood sticks placed in the dehumidification tube 62 to ensure that the air pressure in the dehumidification tube 62 can drive the fan 74 to rotate. When the air pressure in the sealed space reaches the pressure value of the overflow valve, the overflow valve will open to allow the high-pressure gas to be ejected to drive the fan 74 to rotate. At the same time, the material of the dehumidification tube 62 can be selected as aluminum oxide. Aluminum oxide has high hardness, high temperature resistance and light weight, so that the high-speed smoke can blow the fan 74 to rotate at a low speed. When the high-temperature smoke passes through the fan 74, the high-temperature smoke blows the fan 74 to drive the dehumidification tube 62 to rotate slowly, thereby not affecting the high-temperature smoke to dehumidify the firewood sticks in the dehumidification tube 62. On the contrary, if the rotation speed of the dehumidification tube 62 is too fast, the smoke cannot fully heat the dehumidification tube 62, but affects the dehumidification of the firewood sticks. Since the fan 74 is fixedly connected to the No. 1 rotating shaft 72, The fan 74 drives the No. 1 rotating shaft 72 to rotate together. Since the dehumidification cylinder 62 is fixedly connected to the No. 1 rotating shaft 72, the No. 1 rotating shaft 72 drives the dehumidification cylinder 62 to rotate together, so that the dehumidification cylinder 62 can achieve the effect of uniform heat treatment. Since the No. 2 shell 71 is connected to the No. 1 shell 61, the smoke enters the heating chamber 63 in the No. 1 shell 61 through the No. 2 shell 71, and the dehumidification cylinder 62 is heated by the heat of the smoke, thereby achieving the effect of evenly heating the dehumidification cylinder 62. The firewood sticks are dried and dehumidified to reduce the influence of moisture in the firewood sticks on the carbonization of the firewood sticks when they are carbonized in the carbonization furnace. Since the heat of the flue gas is used to heat and dehumidify the firewood sticks in the dehumidification cylinder 62, the smoke blowing fan 74 drives the dehumidification cylinder 62 to rotate slowly and does not affect the high-temperature smoke from dehumidifying the firewood sticks in the dehumidification cylinder 62. On the contrary, if the dehumidification cylinder 62 rotates too fast, the smoke cannot fully heat the dehumidification cylinder 62, which affects the dehumidification of the firewood sticks.

[0055] As a specific implementation of the present invention, a carbonization furnace 8 is rotatably connected inside the furnace body 1 , and a second rotating shaft 9 is fixedly connected inside the carbonization furnace 8 .

[0056] As a specific implementation of the present invention, a mounting frame 10 is provided outside the furnace body 1 , and a motor 11 is fixedly connected to the mounting frame 10 , and the motor 11 is fixedly connected to one end of the second rotating shaft 9 .

[0057] The present invention is connected with a carbonization furnace 8 rotatably in a furnace body 1, a second rotating shaft 9 is fixedly connected in the carbonization furnace 8, a mounting frame 10 is provided outside the furnace body 1, a motor 11 is fixedly connected to the mounting frame 10, a driving shaft of the motor 11 is fixedly connected to one end of the second rotating shaft 9, when the firewood sticks after dehumidification are carbonized, the furnace cover 2 is opened, the firewood sticks are put into the carbonization furnace 8, and the motor 11 is started to drive the second rotating shaft 9 to rotate. Since the second rotating shaft 9 is fixedly connected to the carbonization furnace 8, the second rotating shaft 9 drives the carbonization furnace 8 to rotate in the furnace body 1, so that the firewood sticks in the carbonization furnace 8 can be evenly heated, so as to improve the efficiency of the carbonization of the firewood sticks, and also accelerate the speed of smoke generation when the firewood sticks are carbonized.

[0058] As a specific embodiment of the present invention, a sealing member 12 is rotatably connected to the outer surface of one side of the carbonization furnace 8 close to the motor 11, and a No. 1 air guide hole 121 is provided in the sealing member 12. An air guide pipe 13 is fixedly connected to the sealing member 12, and one end of the air guide pipe 13 is connected to the No. 1 air guide hole 121, and the other end of the air guide pipe 13 is connected to the No. 2 shell 71. A No. 2 air guide hole 81 is provided in the carbonization furnace 8, and the No. 2 air guide hole 81 is connected to the No. 1 air guide hole 121.

[0059] The present invention is provided with a sealing member 12 which is rotatably connected to a side of the carbonization furnace 8 close to the motor 11, a No. 1 air guide hole 121 is provided in the sealing member 12, an air guide pipe 13 is fixedly connected to the sealing member 12, one end of the air guide pipe 13 is connected to the No. 1 air guide hole 121, and the other end of the air guide pipe 13 is connected to the No. 2 shell 71, a No. 2 air guide hole 81 is provided in the carbonization furnace 8, and the No. 2 air guide hole 81 is connected to the No. 1 air guide hole 121. When the carbonization furnace 8 carbonizes the firewood sticks, the smoke generated by the firewood sticks moves into the No. 2 air guide hole 81 on the carbonization furnace 8. Since the No. 2 air guide hole 81 is connected to a pipe protruding from the No. 1 air guide hole 121 in the sealing member 12, the No. 2 air guide hole 81 is annular in structure, and the No. 1 air guide hole 121 protrudes The pipe is inserted into the No. 2 air guide hole 81, so the smoke moves from the No. 2 air guide hole 81 to the No. 1 air guide hole 121. Since the No. 1 air guide hole 121 is connected with the air guide pipe 13, and the No. 2 shell 71 is connected with the No. 1 air guide hole 121 through the air guide pipe 13, the smoke moves into the No. 2 shell 71 through the air guide pipe 13, thereby achieving the effect of passing the smoke generated in the carbonization furnace 8 into the No. 2 shell 71 to blow the fan 74 to rotate. At the same time, the smoke does not directly contact the No. 2 rotating shaft 9, avoiding the risk of explosion caused by sparks generated by the rotation of the motor 11 and igniting the smoke. In order to facilitate the seal 12 and the carbonization furnace 8 to have a certain degree of sealing while rotating, the material of the seal 12 is a hard rubber material.

[0060] As a specific implementation of the present invention, a groove 21 is formed on the inner surface of the furnace cover 2 , and the other end of the second rotating shaft 9 is located in the groove 21 .

[0061] The present invention opens a groove 21 on the inner surface of the furnace cover 2, and the other end of the No. 2 rotating shaft 9 is located in the groove 21. The No. 2 rotating shaft 9 is rotatably connected to the groove 21, so that the groove 21 serves as a support for the No. 2 rotating shaft 9, thereby achieving the effect of facilitating the rotation of the No. 2 rotating shaft 9. At the same time, the No. 2 rotating shaft 9 does not hinder the opening of the furnace cover 2.

[0062] As a specific implementation of the present invention, partitions 14 are evenly arranged in the carbonization furnace 8 .

[0063] As a specific embodiment of the present invention, the partition plate 14 is provided with ventilation holes 141 , and the number of the ventilation holes 141 decreases in sequence from the furnace cover 2 to the motor 11 .

[0064] The present invention arranges partitions 14 evenly in the carbonization furnace 8, and the partitions 14 are sleeved on the second rotating shaft 9 to separate the firewood sticks in the carbonization furnace 8, reduce the impact of the carbonization furnace 8 on the firewood sticks when rotating, facilitate the carbonization of the firewood sticks, and also play a certain fixing role on the firewood sticks. Since the firewood sticks in the carbonization furnace 8 are separated by the partitions 14, the firewood sticks are more complete after carbonization. By opening air vents 141 on the partitions 14, and the number of the air vents 141 decreases in sequence from the furnace cover 2 to the direction of the motor 11, when the motor 11 drives the carbonization furnace 8 to rotate, the smoke in the carbonization furnace 8 enters the No. 1 air guide hole 121 through the air vents 141 on the partitions 14, since the number of the air vents 141 decreases in sequence from the furnace cover 2 to the direction of the motor 11, when the smoke in the carbonization furnace 8 moves from the direction close to the furnace cover 2 to the No. 2 air guide hole 81, due to the close The number of air vents 141 on the partition 14 near the furnace cover 2 is relatively large, so that the flue gas can flow more easily from the furnace cover 2 side to the motor 11 side. Since it is necessary to increase the air pressure in the carbonization furnace 8 as much as possible, the air vents 141 on the partition 14 near the motor 11 side are arranged less than those of other partitions 14, so that the air outlet of the air vents 141 on the partition 14 near the motor 11 side is relatively small, thereby achieving the purpose of increasing the pressure of the flue gas inside the carbonization furnace 8, that is, the amount of flue gas generated inside the carbonization furnace 8 is higher than the amount discharged from the air vents 141 near the motor 11 side; the air pressure of the flue gas in the carbonization furnace 8 becomes higher and the flow rate becomes faster in the process of entering the No. 2 air guide hole 81 through the air vents 141 on the partition 14, and the high-flow rate flue gas enters the air guide pipe 13 through the No. 2 air guide hole 81, thereby facilitating the rotation of the flue gas blowing fan 74.

[0065] As a specific implementation of the present invention, the material of the first shell 61 is a heat insulating material.

[0066] The present invention selects heat-insulating materials as the material of the No. 1 shell 61, such as ceramic fiber, high-temperature resistant heat-insulating cotton, etc. Since the heat-insulating materials have a certain heat-insulating effect, the flue gas can fully utilize the heat of the flue gas to dehumidify the damp firewood rods in the dehumidification cylinder 62 after entering the heating chamber 63.

[0067] Working principle: Firewood sticks are widely used as a common carbonized material. Compared with log carbonization, firewood sticks have regular shapes and are not easy to deform after carbonization. However, firewood sticks contain about 8% moisture when entering the carbonization furnace. This moisture is the enemy of carbonization, and machine-made firewood sticks are very susceptible to moisture. The moisture in the firewood sticks seriously affects the carbonization quality of the firewood sticks. In the prior art, the staff often put the firewood sticks into the carbonization furnace for two to three hours of drying. However, the firewood sticks will produce water vapor when being dried, and the water vapor still has a certain effect on the carbonization of the firewood sticks.

[0068] Therefore, the present invention is provided with a dehumidification unit 6 outside the furnace body 1. Before opening the furnace cover 2 through the locking clip 3 on the furnace body 1 to send the next batch of firewood sticks into the carbonization furnace for carbonization, the staff can first use the dehumidification unit 6 to dehumidify the firewood sticks. A power unit 7 is arranged between the dehumidification unit 6 and the furnace body 1. The power unit 7 is connected to the furnace body 1. Flue gas is generated in the process of carbonization of the firewood sticks. The flue gas is introduced into the power unit 7 so that the power unit 7 provides power for the dehumidification unit 6. Then the flue gas enters the dehumidification unit 6 through the power unit 7, so that the dehumidification unit 6 can better dehumidify the firewood sticks before carbonization, so as to reduce the influence of moisture on the carbonization quality of the firewood sticks when the firewood sticks enter the carbonization furnace. Then the flue gas enters the purifier 5 from the dehumidification unit 6 to purify the flue gas. The purified flue gas enters the heater 4 through a pipeline to heat the carbonization furnace, thereby realizing the secondary utilization of the flue gas.

[0069] The present invention provides a first shell 61 on one side close to the purifier 5, a dehumidification cylinder 62 is rotatably connected in the first shell 61, a heating chamber 63 is provided in the first shell 61, a second shell 71 is fixedly connected to one side of the first shell 61, the second shell 71 is communicated with the heating chamber 63 of the first shell 61, a first rotating shaft 72 is rotatably connected in the second shell 71 through a fixing frame 73, a fan 74 is fixedly connected to one end of the first rotating shaft 72, and the other end of the first rotating shaft 72 is fixedly connected to the dehumidification cylinder 62;

[0070] The staff first puts the damp firewood sticks into the dehumidification cylinder 62, and then introduces the smoke generated when the firewood sticks are carbonized into the second shell 71. Since the carbonized firewood sticks are in a sealed space, a large amount of smoke is generated during the carbonization of the firewood sticks. At this time, a certain air pressure will be generated in the relatively sealed space, and an overflow valve is provided at the outlet of the smoke flow. When in use, the pressure value of the overflow valve can be adjusted according to the number of firewood sticks placed in the dehumidification cylinder 62 to ensure that the air pressure in the dehumidification cylinder can drive the fan 74 to rotate. When the air in the sealed space is When the pressure reaches the pressure value of the relief valve, the relief valve will open to allow the high-pressure gas to be ejected to drive the fan 74 to rotate. At the same time, the material of the dehumidification cylinder 62 can be selected as aluminum oxide. Aluminum oxide has high hardness, high temperature resistance and light weight, so that the high-speed flue gas can blow the fan 74 to rotate at a low speed. When the high-temperature flue gas passes through the fan 74, the high-temperature flue gas blows the fan 74 to drive the dehumidification cylinder 62 to rotate slowly, thereby not affecting the high-temperature flue gas to dehumidify the firewood rods in the dehumidification cylinder 62. On the contrary, if the rotation speed of the dehumidification cylinder 62 is too fast, the flue gas cannot dehumidify the firewood rods in the dehumidification cylinder 62. The moisture cylinder 62 is fully heated, which affects the dehumidification of the firewood sticks. Since the fan 74 is fixedly connected to the No. 1 rotating shaft 72, the fan 74 drives the No. 1 rotating shaft 72 to rotate together. Since the dehumidification cylinder 62 is fixedly connected to the No. 1 rotating shaft 72, the No. 1 rotating shaft 72 drives the dehumidification cylinder 62 to rotate together, so that the dehumidification cylinder 62 is evenly heated. Since the No. 2 shell 71 is connected to the No. 1 shell 61, the smoke enters the heating chamber 63 in the No. 1 shell 61 through the No. 2 shell 71, and the heat of the smoke is used to heat the dehumidification cylinder. 62 is heated, thereby achieving the effect of drying and dehumidifying the damp firewood sticks in the dehumidification cylinder 62, so as to reduce the influence of moisture in the firewood sticks on the carbonization of the firewood sticks when the firewood sticks are carbonized in the carbonization furnace. Since the heat of the flue gas is used to heat and dehumidify the firewood sticks in the dehumidification cylinder 62, the smoke blowing fan 74 drives the dehumidification cylinder 62 to rotate slowly and does not affect the high-temperature smoke from dehumidifying the firewood sticks in the dehumidification cylinder 62. On the contrary, if the dehumidification cylinder 62 rotates too fast, the smoke cannot fully heat the dehumidification cylinder 62, which affects the dehumidification of the firewood sticks.

[0071] The present invention is connected with a carbonization furnace 8 rotatably in a furnace body 1, a second rotating shaft 9 is fixedly connected in the carbonization furnace 8, a mounting frame 10 is provided outside the furnace body 1, a motor 11 is fixedly connected to the mounting frame 10, a driving shaft of the motor 11 is fixedly connected to one end of the second rotating shaft 9, when the firewood sticks after dehumidification are carbonized, the furnace cover 2 is opened, the firewood sticks are put into the carbonization furnace 8, and the motor 11 is started to drive the second rotating shaft 9 to rotate. Since the second rotating shaft 9 is fixedly connected to the carbonization furnace 8, the second rotating shaft 9 drives the carbonization furnace 8 to rotate in the furnace body 1, so that the firewood sticks in the carbonization furnace 8 can be evenly heated, so as to improve the efficiency of the carbonization of the firewood sticks, and also accelerate the speed of smoke generation when the firewood sticks are carbonized.

[0072] The present invention is provided with a sealing member 12 which is rotatably connected to a side of the carbonization furnace 8 close to the motor 11, a No. 1 air guide hole 121 is provided in the sealing member 12, an air guide pipe 13 is fixedly connected to the sealing member 12, one end of the air guide pipe 13 is connected to the No. 1 air guide hole 121, and the other end of the air guide pipe 13 is connected to the No. 2 shell 71, a No. 2 air guide hole 81 is provided in the carbonization furnace 8, and the No. 2 air guide hole 81 is connected to the No. 1 air guide hole 121. When the carbonization furnace 8 carbonizes the firewood sticks, the smoke generated by the firewood sticks moves into the No. 2 air guide hole 81 on the carbonization furnace 8. Since the No. 2 air guide hole 81 is connected to a pipe protruding from the No. 1 air guide hole 121 in the sealing member 12, the No. 2 air guide hole 81 is annular in structure, and the No. 1 air guide hole 121 protrudes The pipe is inserted into the No. 2 air guide hole 81, so the smoke moves from the No. 2 air guide hole 81 to the No. 1 air guide hole 121. Since the No. 1 air guide hole 121 is connected with the air guide pipe 13, and the No. 2 shell 71 is connected with the No. 1 air guide hole 121 through the air guide pipe 13, the smoke moves into the No. 2 shell 71 through the air guide pipe 13, thereby achieving the effect of passing the smoke generated in the carbonization furnace 8 into the No. 2 shell 71 to blow the fan 74 to rotate. At the same time, the smoke does not directly contact the No. 2 rotating shaft 9, avoiding the risk of explosion caused by sparks generated by the rotation of the motor 11 and igniting the smoke. In order to facilitate the seal 12 and the carbonization furnace 8 to have a certain degree of sealing while rotating, the material of the seal 12 is a hard rubber material.

[0073] The present invention opens a groove 21 on the inner surface of the furnace cover 2, and the other end of the No. 2 rotating shaft 9 is located in the groove 21. The No. 2 rotating shaft 9 is rotatably connected to the groove 21, so that the groove 21 serves as a support for the No. 2 rotating shaft 9, thereby achieving the effect of facilitating the rotation of the No. 2 rotating shaft 9. At the same time, the No. 2 rotating shaft 9 does not hinder the opening of the furnace cover 2.

[0074] The present invention arranges partitions 14 evenly in the carbonization furnace 8, and the partitions 14 are sleeved on the second rotating shaft 9 to separate the firewood sticks in the carbonization furnace 8, reduce the impact of the carbonization furnace 8 on the firewood sticks when rotating, facilitate the carbonization of the firewood sticks, and also play a certain fixing role on the firewood sticks. Since the firewood sticks in the carbonization furnace 8 are separated by the partitions 14, the firewood sticks are more complete after carbonization. By opening air vents 141 on the partitions 14, and the number of the air vents 141 decreases in sequence from the furnace cover 2 to the direction of the motor 11, when the motor 11 drives the carbonization furnace 8 to rotate, the smoke in the carbonization furnace 8 enters the No. 1 air guide hole 121 through the air vents 141 on the partitions 14, since the number of the air vents 141 decreases in sequence from the furnace cover 2 to the direction of the motor 11, when the smoke in the carbonization furnace 8 moves from the direction close to the furnace cover 2 to the No. 2 air guide hole 81, due to the close The number of air vents 141 on the partition 14 near the furnace cover 2 is relatively large, so that the flue gas can flow more easily from the furnace cover 2 side to the motor 11 side. Since it is necessary to increase the air pressure in the carbonization furnace 8 as much as possible, the air vents 141 on the partition 14 near the motor 11 side are arranged less than those of other partitions 14, so that the air outlet of the air vents 141 on the partition 14 near the motor 11 side is relatively small, thereby achieving the purpose of increasing the pressure of the flue gas inside the carbonization furnace 8, that is, the amount of flue gas generated inside the carbonization furnace 8 is higher than the amount discharged from the air vents 141 near the motor 11 side; the air pressure of the flue gas in the carbonization furnace 8 becomes higher and the flow rate becomes faster in the process of entering the No. 2 air guide hole 81 through the air vents 141 on the partition 14, and the high-flow rate flue gas enters the air guide pipe 13 through the No. 2 air guide hole 81, thereby facilitating the rotation of the flue gas blowing fan 74.

[0075] The present invention selects heat-insulating materials as the material of the No. 1 shell 61, such as ceramic fiber, high-temperature resistant heat-insulating cotton, etc. Since the heat-insulating materials have a certain heat-insulating effect, the flue gas can fully utilize the heat of the flue gas to dehumidify the damp firewood rods in the dehumidification cylinder 62 after entering the heating chamber 63.
