[0079] In one optional implementation, the control method for the high-efficiency pyrolysis furnace includes the following steps:

[0080] The second pyrolysis furnace 2 is equipped with a temperature sensor; the temperature sensor acquires the real-time temperature of the second pyrolysis furnace 2.

[0081] When the temperature sensor detects that the temperature of the second pyrolysis furnace 2 has reached the first temperature, it sends a first signal to the controller;

[0082] After receiving the first signal, the controller controls the first driving device to move the first pyrolysis furnace 1 to a first position below the adjacent second pyrolysis furnace 2. When the proximity switch detects that the first pyrolysis furnace 1 has reached the first position, it sends a second signal to the controller. After receiving the second signal, the controller controls the first driving device to stop moving, thereby stopping the first pyrolysis furnace 1 at the first position and heating the second pyrolysis furnace 2 above it. The above steps are repeated until all the second pyrolysis furnaces 2 are heated to the first temperature.

[0083] The first temperature is 490℃~510℃.

[0084] In one optional implementation, the control method for the high-efficiency pyrolysis furnace includes the following steps:

[0085] The controller reads all temperature data from the second pyrolysis furnace 2;

[0086] The controller controls the first drive device to operate, driving the first pyrolysis furnace 1 to move below a second pyrolysis furnace 2 that has not reached the first temperature and has the lowest temperature, and to heat it;

[0087] Once the temperature of the second pyrolysis furnace 2 reaches the first temperature, the controller then controls the first drive device to operate, driving the first pyrolysis furnace 1 to move below another second pyrolysis furnace 2 that has not reached the first temperature and has the lowest temperature, and to heat it.

[0088] Repeat the above steps until the temperature of all the second pyrolysis furnaces 2 reaches the first temperature;

[0089] The first temperature is 90℃~510℃.

[0090] Example 3:

[0091] This embodiment provides a method for burning organic matter. The method uses the high-efficiency pyrolysis furnace described in Embodiment 1 and includes the following steps: straw is fed into the combustion chamber 11 through the first feeding device; the support part 221 of the second feeding device 22 is pulled out, wood is placed in the support part 221, and then the support part 221 is pushed into the pyrolysis carbonization chamber 21 and the latch is locked so that the chamber door 272 is tightly against the front end face of the furnace wall 27 of the second pyrolysis furnace 2; the gasification swirl burner is turned on to ignite the straw; at this time, the exhaust valve 235 of the pyrolysis carbonization chamber 21... When the pyrolysis carbonization chamber 21 is in the closed state, the drain valve 234 is in the open state, and the water produced by the wood pyrolysis will first be discharged from the drain valve 234. After the first pyrolysis, the drain valve 234 is closed. At this time, the wood pyrolysis produces high-temperature flue gas, which is discharged from the flame outlet 111 of the first pyrolysis furnace 1 through the first conduit 23, playing a role in combustion. At the same time, the flue gas also enters the heat preservation chamber 12 of the first pyrolysis furnace 1 through the second conduit 25, raising the temperature of the first pyrolysis furnace 1 from 240℃~260℃ to 490℃~510℃. When the wood in the pyrolysis carbonization chamber 21 is completely pyrolyzed, the exhaust valve 235 of the pyrolysis carbonization chamber 21 is opened, and the flue gas is discharged to the next process through the exhaust port of the extension section 2321. The next process may be a heat exchange device and a purification device connected in sequence. Once the temperature inside the pyrolysis carbonization chamber 21 has dropped to room temperature, the support part 221 is removed, and the residue inside the support part 221 and the pyrolysis carbonization chamber 21 is cleaned.
