[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a garbage biomass gasification furnace, including a furnace body 1 and a water tank 8. A top cover 2 is installed on the top of the furnace body 1. The top cover 2 and the furnace body 1 are clamped by a hydraulic structure to ensure the stability of the connection between the top cover 2 and the furnace body 1, and at the same time, it is convenient to send the garbage into the furnace body 1 for gasification treatment. A discharge port 3 is fixedly connected to the bottom of the furnace body 1, and a grille 4 is fixedly connected to the inside of the discharge port 3. The grille 4 can block the residue after the garbage is heated and gasified to prevent it from falling directly to the outside. At the same time, the grille 4 can also provide sufficient air for the gasification process. A discharge basket 5 is fixedly connected to the bottom wall of the furnace body 1. A plurality of vents 6 are opened inside the discharge basket 5. An air inlet pipe 7 is installed on one side of the outside of the furnace body 1. Air can be injected into the furnace body 1 through the air inlet pipe 7. The air enters the furnace body 1 after being diverted through the vents 6 on the discharge basket 5, thereby accelerating and promoting the gasification reaction.

[0032] Reference Figure 1 and Figure 2An exhaust pipe 9 is connected between the water tank 8 and the furnace body 1, a spiral tube 10 is fixedly connected inside the water tank 8, and a purification component is installed in the middle of the exhaust pipe 9. The gas generated by gasification inside the furnace body 1 will directly enter the water tank 8 through the exhaust pipe 9. During the process, the gas will pass through the inside of the purification component to filter and purify the large particles of impurities in the gas. The air inlet pipe 7 is arranged between the bottom of the discharge basket 5 and the inner bottom wall of the furnace body 1, so that the air inside the air inlet pipe 7 can evenly enter the furnace body 1 through the vents 6 on the discharge basket 5, and assist the furnace body 1 to gasify the garbage. The top of the grille 4 is fixedly connected to the bottom of the discharge basket 5. The discharge basket 5 with a conical structure can allow the gasified material to fall directly on the grille 4, while preventing the gasification product from being directly discharged from the furnace body 1. A bracket 12 is fixedly connected to the outside of the furnace body 1, and the bracket 12 can effectively support the furnace body 1. The spiral tube 10 is connected to the exhaust pipe 9, and an air outlet 11 is fixedly connected to the side of the water tank 8 away from the furnace body 1. The air outlet 11 and the spiral tube 10 are connected, and the high-temperature gas obtained by vaporization and discharged from the exhaust pipe 9 will directly enter the spiral tube 10. Since the spiral tube 10 is made of copper, it has good thermal conductivity, so that the high-temperature gas will transfer the temperature to the water inside the water tank 8 through the spiral tube 10, and the spiral structure of the pipe can increase the time for the high-temperature gas to transfer heat to the water, thereby recovering the heat in the high-temperature gas obtained by vaporization as much as possible.

[0033] Reference Figure 2-Figure 4The purification assembly includes a purification box 13, the outer side of the purification box 13 is fixedly connected to the outer wall of the furnace body 1, the inside of the purification box 13 is slidably connected with a movable block 14, the rear side of the movable block 14 is fixedly connected with an activated carbon mesh plate 15, a slide groove 16 is provided inside the movable block 14, both sides of the slide groove 16 are slidably connected with a plug rod 17, a slider 18 is slidably connected inside the movable block 14, a button 19 is fixedly connected to one side of the middle of the slider 18, a spring 20 is provided on the other side of the middle of the slider 18, and a connecting rod 21 is provided between the slider 18 and the plug rod 17. The high-temperature gas to be generated will enter the purification box 13 through the exhaust pipe 9, and the gas transported from the exhaust pipe 9 will be filtered through the activated carbon mesh plate 15 to remove particulate matter in the gas and purify the gas obtained by gasification. When the activated carbon mesh 15 is slowly clogged, the worker presses the button 19 and pulls out the movable block 14, so that the button 19 moves and pushes the slider 18 to move inside the movable block 14, so that the slider 18 compresses the spring 20, and the slider 18 moves and pushes the two connecting rods 21 to move, and the corresponding plug rods 17 are driven to shrink toward the inside of the slide groove 16 through the two connecting rods 21, and then the plug rods 17 and the inner wall of the purification box 13 are separated, and the movable block 14 and the purification box 13 are released from the locked state. When the worker pulls the handle on the outside of the movable block 14, the movable block 14 and the activated carbon mesh 15 can be easily pulled out of the purification box 13 together, and then the activated carbon mesh 15 can be quickly replaced. The outer side of the activated carbon mesh 15 is inserted into the purification box 13, and the outer periphery of the plug rod 17 passes through the movable block 14 and is inserted into the purification box 13. The movable block 14 is restricted and fixed inside the purification box 13 by the plug rod 17, and then the activated carbon mesh 15 is restricted and fixed inside the purification box 13, ensuring that the activated carbon mesh 15 can stably purify the large particles of impurities and harmful substances in the gas obtained by filtering and gasification. One end of the spring 20 is fixedly connected to the middle side of the inner wall of the movable block 14, and the other end of the spring 20 is fixedly connected to the side of the middle of the slider 18 away from the button 19. The pressure applied by the spring 20 to the slider 18 can ensure that the slider 18 tightly pulls the connecting rod 21, thereby ensuring that the plug rod 17 will not separate from the inner wall of the purification box 13. One end of the connecting rod 21 is hinged to the edge of the slider 18, and the other end of the connecting rod 21 is hinged to the outside of the insertion rod 17. The connecting rod 21 can allow the slider 18 to directly drive the two insertion rods 17 to move inside the slide groove 16 when it moves, thereby controlling the insertion rod 17 to insert into the inner wall of the purification box 13 or detach from the inner wall of the purification box 13.

[0034] Working principle: After opening the top cover 2, put the garbage to be processed into the furnace body 1, then close the top cover 2 and start the furnace body 1 to heat the inside of the gasifier. During the process, water vapor is injected into the furnace body 1 through the air inlet pipe 7, so that the furnace body 1 is filled with water vapor, which is then used as a gasifying agent. As the temperature inside the furnace body 1 continues to rise, the garbage and water vapor inside the furnace body 1 come into contact with each other to produce a gasification reaction. At the same time, air can be injected into the furnace body 1 through the air inlet pipe 7. The air is diverted through the vents 6 on the discharge basket 5 and then enters the furnace body 1, thereby accelerating and promoting the gasification reaction. Afterwards, the high-temperature gas generated by the reaction will enter the purification box 13 through the exhaust pipe 9, and the gas transported out of the exhaust pipe 9 will be filtered by the activated carbon mesh plate 15 to remove particulate matter in the gas and purify the gas obtained by gasification. Then, the gas passes through the purification box 13 and enters the spiral tube 10. Since the spiral tube 10 is made of copper, it has good thermal conductivity, so that the high-temperature gas will transfer the temperature to the water inside the water tank 8 through the spiral tube 10, and the spiral structure of the pipe can increase the time for the high-temperature gas to transfer heat to the water, thereby recovering the heat in the high-temperature gas obtained by gasification as much as possible. At the same time, the heated water inside the water tank 8 can be used to preheat the furnace body 1, so that before the furnace body 1 is started, the water inside the water tank 8 can be pumped out and injected into the interlayer inside the furnace body 1, and then the furnace body 1 is preheated in advance, so that the furnace body 1 can reach the working temperature faster during operation, thereby reducing the power consumption of the furnace body 1.

[0035] When the activated carbon mesh 15 is slowly clogged, the worker presses the button 19 and pulls out the movable block 14, so that the movement of the button 19 pushes the slider 18 to move inside the movable block 14, so that the slider 18 compresses the spring 20, and the movement of the slider 18 pushes the two connecting rods 21 to move, and the corresponding insertion rod 17 is driven by the two connecting rods 21 to shrink toward the inside of the slide groove 16, thereby disengaging the insertion rod 17 from the inner wall of the purification box 13, and the movable block 14 and the purification box 13 are released from the locked state. When the worker pulls the handle on the outside of the movable block 14, the worker can easily pull the movable block 14 and the activated carbon mesh 15 out of the purification box 13, and then quickly complete the replacement of the activated carbon mesh 15. After that, it is only necessary to insert the new activated carbon mesh 15 and the movable block 14 into the purification box 13, and release the button 19 at the same time. At this time, the compressed spring 20 is reset to push the slider 18 to move, and then the slider 18 drives the two insertion rods 17 again through the connecting rod 21 and inserts them into the inner wall of the purification box 13, so that the installation of the movable block 14 and the activated carbon mesh 15 is completed quickly and conveniently.
