[0011] This invention provides a biomass gasification reactor with a high gasification rate, which has the following beneficial effects:

[0012] In use, this invention uses a rotating component to rotate the solid waste generated from biomass gasification. Under centrifugal force, the waste is discharged through the discharge chute. During the gasification reaction, the biomass is placed inside the gasification reactor for gasification. The solid waste generated during the gasification reaction falls onto the rotating component through the discharge hole on the gasification carrier plate. After the rotating component rotates, the solid waste is thrown out through the discharge chute under centrifugal force, reducing the problem of solid waste accumulation.

During the gasification reaction, the biomass is fed into the pretreatment tank. The smaller biomass particles crushed by the blades on the outside of the rotating rod flow downwards through the discharge hole on the movable plate into the gasification reaction tank. The smaller biomass particles have increased reactivity under high temperature, thereby improving the gasification efficiency. Attached Figure Description

[0029] This utility model proposes a biomass gasification reactor with high gasification rate, comprising: a gasification reactor 1, which is cylindrical in shape and has a closed cover plate installed on its top; an exhaust pipe is provided on one side of the top of the gasification reactor 1; a groove is provided in the middle of the bottom of the gasification reactor 1, and a drive motor is installed inside the groove; a gasification carrier plate 101 is installed on the inner side of the gasification reactor 1, wherein the gasification carrier plate 101 has multiple discharge holes; and a discharge trough 102 is provided at the bottom of the outer side of the gasification reactor 1. A positioning ring 103 is provided on the inner bottom of the gasification tank 1; the positioning ring 103 is located at the bottom of the gasification carrier plate 101; a rotating component 104 is rotatably installed on the inner bottom of the gasification tank 1; the rotating component 104 has a conical structure, and a coil heating module 105 is installed on the top of the rotating component 104; the side end of the coil heating module 105 is rotatably installed on the inner side of the positioning ring 103; a collection cover 106 is installed on the outer bottom of the gasification tank 1; the collection cover 106 is located on the outer side of the discharge trough 102, and a sealing plate 107 is installed on the bottom of the collection cover 106.

[0030] In this embodiment, during the biomass gasification reaction, the biomass fed onto the gasification carrier plate 101 is heated by the coil heating module 105 to carry out the gasification reaction. The combustible gas generated after gasification flows out through the exhaust pipe on one side of the top of the gasification reaction tank 1 to the designated equipment. Some of the solid waste generated after the biomass gasification reaction falls downward onto the rotating component 104 through the discharge hole on the gasification carrier plate 101. The drive motor in the groove at the bottom of the gasification reaction tank 1 drives the rotating component 104 to rotate at the bottom of the inner side of the gasification reaction tank 1. The rotating component 104 drives the solid waste to rotate and is thrown out through the discharge trough 102 under the action of centrifugal force. The collection hood 106 collects the solid waste. When a certain amount is collected, the sealing plate 107 is opened to process the solid waste.

[0031] In Example 2, based on Example 1, a guide pipe 2 is installed on the other side of the top of the gasification reactor 1; a pretreatment tank 201 is installed on the top of the guide pipe 2; the bottom of the pretreatment tank 201 is conical, and a servo motor is installed on the top of the pretreatment tank 201; a fixed support plate 202 is installed on the inner bottom of the pretreatment tank 201; movable plates 203 are installed on both sides of the top of the fixed support plate 202 via springs; the top of the movable plate 203 is provided with a discharge hole, and the movable plate 203 is installed vertically on the inner side of the pretreatment tank 201; a rotating rod 204 is installed on the output end of the servo motor at the top of the pretreatment tank 201; the rotating rod 204 is cylindrical, and the bottom end of the rotating rod 204 passes through the movable plate 203 and is installed on the fixed support plate 202; a blade is installed on the outer side of the rotating rod 204, the blade is above the movable plate 203, and a planetary gear set 205 is installed at the bottom of the rotating rod 204; the bottom of the movable plate 203 is provided with three pressure points. Force block 206; guide block 207 is installed on the side of planetary gear set 205; the top of guide block 207 is a hemispherical structure, and guide block 207 is rotatably installed on the outside of force block 206. During the biomass gasification reaction, the biomass is placed inside the pretreatment tank 201. The servo motor at the top of the pretreatment tank 201 drives the blades on the outside of the rotating rod 204 to crush the biomass. At the same time, the bottom of the rotating rod 204 rotates on the fixed support plate 202. After the rotating rod 204 drives the planetary gear set 205 to rotate, the rotation speed of guide block 207 is reduced. After guide block 207 touches force block 206, it drives movable plate 203 to move up and down on the outside of rotating rod 204 and the inside of pretreatment tank 201. The crushed biomass with smaller particles flows downward through the discharge hole on movable plate 203. The crushed biomass flows into the inside of gasification reaction tank 1 through guide pipe 2. The smaller particles accelerate the gasification reaction efficiency of biomass.

[0032] In Example 3, based on Example 1, a preheating pipe 3 is installed on the outside of the guide pipe 2; an air inlet pipe 301 is installed at the bottom of the preheating pipe 3; an suction pipe 302 is installed on the inside of the gasification reactor 1; the suction pipe 302 has an annular structure and an air hole at the bottom; the side of the suction pipe 302 is connected to the bottom of the air inlet pipe 301 that penetrates the side of the gasification reactor 1; an air outlet pipe 303 is installed at the top of the preheating pipe 3; the side end of the air outlet pipe 303 is connected to the outside of the gasification reactor 1. During the gasification reaction of biomass, the gas flow generated by the biomass gasification reaction is at a high temperature and flows upward. Part of the gas flow enters the interior of the air inlet pipe 301 through the suction pipe 302, and the hot gas flow enters the interior of the preheating pipe 3 through the air inlet pipe 301 to preheat the biomass flowing in the guide pipe 2, further improving the gasification reaction efficiency of biomass. The gas flow then flows back to the interior of the gasification reactor 1 through the air outlet pipe 303, so that the heat is fully utilized.

[0033] The working principle of this embodiment is as follows: Biomass is placed in the pretreatment tank 201. The servo motor at the top of the pretreatment tank 201 drives the blades on the outside of the rotating rod 204 to crush the biomass. At the same time, the bottom of the rotating rod 204 drives the planetary gear set 205 to rotate, which reduces the rotation speed of the guide block 207. The guide block 207 pushes the force block 206 to move the movable plate 203 up and down. The crushed biomass particles, which are smaller, flow downward through the discharge hole on the movable plate 203 and through the guide pipe 2 to the gasification carrier plate 101 inside the gasification reactor 1. The coil heating module 105 heats the biomass to carry out the gasification reaction. The gasified biomass produces gas... Combustible gas flows out through the exhaust pipe on one side of the top of the gasification reactor 1 into the designated equipment. Some of the solid waste generated after the biomass gasification reaction falls downward onto the rotating part 104 through the discharge hole on the gasification carrier plate 101. The drive motor in the groove at the bottom of the gasification reactor 1 drives the rotating part 104 to rotate. Under the action of centrifugal force, it is thrown out through the discharge trough 102. The gas flow generated by the biomass gasification reaction is high in temperature and flows upward. Some of the hot gas flow enters the inlet pipe 301 through the suction pipe 302 and then enters the preheating pipe 3 to preheat the biomass flowing in the guide pipe 2, further improving the biomass gasification reaction efficiency.
