The lifting trough 8 is a triangular prism structure. When in use, the user places the biomass material inside the material box 1. During the placement process, the first motor 2 can drive the crushing blade 3 to rotate inside the device to cut the material inside the material chamber 4, and the material is crushed and then transmitted to the gasification furnace through the lifting box 5. The interior of 10 is gasified, and the contact area between the materials can be increased after the biomass materials are broken up, so that the area in contact with oxygen during the oxidation process inside the gasifier 10 is reduced, so that the carbon-containing materials can produce more carbon monoxide and hydrogen during the oxidation process, which is convenient for subsequent combustion to produce gas for power generation. The second motor 35 will drive the transmission wheel 6 to rotate inside the device. Since the transmission wheel 6 and the transmission toothed belt 7 are meshed with each other, the transmission wheel 6 will drive the transmission toothed belt 7 to rise and fall inside the device when it rotates, thereby driving the lifting trough 8 outside the transmission toothed belt 7 to rise and fall inside the device. The lifting trough 8 has a triangular prism structure and is hollow inside, so it can bring the material inside the material cavity 4 into the inside of the discharge port 9 for oxidation.

[0031] For example 2, please refer to Figure 1 , Figure 2 and Figure 4 .

[0032] A discharge port 9 is provided on the right side of the lifting box 5, a vaporizer 10 is fixedly installed at the bottom of the discharge port 9, a material port 11 is welded and installed on the top of the vaporizer 10, a chute 12 is evenly provided on the inner wall of the material port 11, a leak plate 13 of mutually matching sizes is installed inside the chute 12, a slider 14 is fixed to the end of the leak plate 13, an ash trough 15 is welded and fixed to the lower part of the vaporizer 10, the ash trough 15 is in an inverted cylindrical shape, a sieve plate 16 is fixedly installed at the bottom of the ash trough 15, an ash removal port 17 is provided at the bottom of the vaporizer 10, and an oxygen transmission port 36 is provided on the front surface of the vaporizer 10, so that the material lifted and transported inside the lifting box 5 passes through the discharge port 9 enters the interior of the gasifier 10 for incomplete combustion. During use, the leakage plate 13 can be disassembled inside the device through the surrounding slider 14 through the slide groove 12, so that the leakage plate 13 can be replaced, which is convenient for the use of the device. Then the material is burned and oxidized inside the gasifier 10. During the oxidation process, a gas containing oxygen or steam is introduced into the interior of the gasifier 10 through the oxygen transmission port 36, and then the solid carbon-containing matter will produce a gas containing carbon monoxide and hydrogen under the action of these gases. Finally, the residue of the solid carbon-containing matter after combustion will pass through the sieve plate 16 and the ash removal port 17 to discharge the device, which is convenient for the use of the device.

After the solid carbon-containing matter undergoes gasification in the gasifier 10, it is discharged into the desulfurization chamber 19 through the air outlet 18 for desulfurization. Since the gas generated by oxidation in the gasifier 10 contains sulfur impurities, it is necessary to perform desulfurization in the desulfurization chamber 19 to facilitate subsequent combustion and avoid environmental pollution. The generated sludge is then discharged from the device through the sludge outlet 20 at the bottom, and then the purified gas can be passed into the combustion chamber 22 through the air ferry 21.

[0034] For example 3, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 .

[0035] A combustion chamber 22 is installed on the right side of the ferry pipe 21, and an air jet 23 is opened on the top of the combustion chamber 22. A turbine body 24 is fixed on the top of the air jet 23. Evenly arranged push blades 25 are installed inside the turbine body 24. The gas containing carbon monoxide and hydrogen that is introduced into the combustion chamber 22 through the ferry pipe 21 will burn inside the combustion chamber 22. After combustion, a large amount of steam and other gases will be generated and enter the interior of the turbine body 24 through the air jet 23. Then the gas generates a huge driving force to drive the internal push blades 25 to rotate inside the device. The kinetic energy is converted into mechanical energy by the push blades 25, and then the inner axis of the push blades 25 is coaxial with the inner axis of the rotating coil 34 on the right, so it can drive the rotating coil 34 to rotate.

[0036] A heat pipe 26 is fixedly installed on the top of the turbine body 24, and a heat exchange box 27 is installed behind the heat pipe 26. The heat pipe 26 is evenly arranged inside the heat exchange box 27. The gas flowing through the turbine body 24 drives the blades 25 to rotate, and there is still excess heat left.

The heat pipe 26 is evenly arranged inside the heat exchange box 27, which can further improve the efficiency of energy exchange of the heat pipe 26 inside the device, avoid energy loss, and facilitate the use of the device.

[0037] Example 4, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 .

[0038] A water pipe 28 is fixedly installed in front of the heat exchange box 27, and a water storage tank 29 is fixed in front of the water pipe 28. A water storage chamber 30 is opened inside the water storage tank 29. The water storage chamber 30 communicates with the heat exchange box 27 through the water pipe 28. A water outlet 31 is installed in front of the water storage tank 29. The water pipe 28 installed in front of the heat exchange box 27 can pass the heated water inside the heat exchange box 27 into the inside of the water pipe 28, so as to facilitate the storage of the heated water.

[0039] For example 5, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 .

[0040] A generator box 32 is installed on the right side of the turbine body 24. An array of fixed magnetic plates 33 are fixed to the inner wall of the generator box 32. Rotating coils 34 with overlapping centers are installed inside the fixed magnetic plates 33. When the pushing blades 25 are rotated by the gas, the rotating coils 34 are coaxial with the pushing blades 25, so the rotating coils 34 will also rotate inside the device. Since fixed magnetic plates 33 are evenly installed outside the rotating coils 34, the rotating coils 34 will cut the magnetic lines of force between the fixed magnetic plates 33 when rotating, and induce current in the generator box 32 through the principle of rotating magnetic field.

[0041] Working principle, first, place the biomass carbon-containing material to be processed into the material box 1, and then the first motor 2 can drive the crushing blade 3 to rotate inside the device to cut the material inside the material chamber 4. After the material is broken, it is transmitted to the inside of the gasifier 10 through the lifting box 5 for gasification. After the biomass material is broken, the contact area between the materials is increased, so that the area of ​​contact with oxygen during the oxidation process inside the gasifier 10 is reduced, so that the carbon-containing material produces more carbon monoxide and hydrogen during the oxidation process, which is convenient for subsequent combustion to generate gas for power generation. The second motor 35 will drive the transmission wheel 6 to rotate inside the device. Since the transmission wheel 6 and the transmission toothed belt 7 are meshed with each other, the transmission wheel 6 will drive the transmission toothed belt 7 to rise and fall inside the device when it rotates, thereby driving the lifting trough outside the transmission toothed belt 7. 8 is lifted and lowered inside the device. The lifting trough 8 is a triangular prism structure and is hollow inside. The material inside the material chamber 4 is brought into the inside of the discharge port 9 for oxidation. Then the material lifted and transported inside the lifting box 5 enters the inside of the gasifier 10 through the discharge port 9 for incomplete combustion. During use, the leakage plate 13 can be disassembled inside the device through the sliding block 14 around it through the slide groove 12, and the leakage plate 13 is replaced to facilitate the use of the device. Then the material is burned and oxidized inside the gasifier 10. During the oxidation process, the gas containing oxygen or steam is introduced into the inside of the gasifier 10 through the oxygen transmission port 36. Then, the solid carbon-containing matter will produce a gas containing carbon monoxide and hydrogen under the action of these gases. Finally, the residue of the solid carbon-containing matter after combustion will pass through the sieve plate 16 and the ash removal port 17 to discharge the device, which is convenient for the use of the device.

[0042] After that, the solid carbon-containing matter undergoes gasification in the gasifier 10 and is discharged into the desulfurization chamber 19 through the gas outlet 18 for desulfurization. Since the gas generated by oxidation in the gasifier 10 contains sulfur impurities, it is necessary to perform desulfurization in the desulfurization chamber 19 to facilitate subsequent combustion and avoid environmental pollution. The generated sludge is then discharged from the device through the sludge port 20 at the bottom, and the purified gas can then be passed into the combustion chamber 22 through the gas ferry 21. The gas containing carbon monoxide and hydrogen that is passed into the combustion chamber 22 through the gas ferry 21 will burn in the combustion chamber 22. After combustion, a large amount of steam and other gases will be generated and enter the turbine body 2 through the jet port 23. 4, and then the gas generates a huge driving force to drive the internal pushing blade 25 to rotate inside the device, and the kinetic energy is converted into mechanical energy by the pushing blade 25, and then the inner axis of the pushing blade 25 is coaxial with the inner axis of the rotating coil 34 on the right, so the rotating coil 34 is driven to rotate. In the process of the pushing blade 25 being driven and rotated by the gas, since the rotating coil 34 is coaxial with the pushing blade 25, the rotating coil 34 will also rotate inside the device. Since fixed magnetic plates 33 are evenly installed outside the rotating coil 34, the rotating coil 34 will cut the magnetic lines of force between the fixed magnetic plates 33 when rotating, and induce current in the generator box 32 through the principle of rotating magnetic field;

[0043] The water conduit 28 installed in front of the heat exchange box 27 can pass the water that has been heated inside the heat exchange box 27 into the water conduit 28, so as to facilitate the storage of the heated water.
