Description

Technical Field

[0001] This utility model relates to the field of gasification furnace devices, and in particular to a biomass gasification furnace. Background Technology

[0002] The existing patent, with publication number "CN220724057U," is titled "A Small Biomass Gasification Furnace." It includes a gasification furnace body with a connecting plate fixed to its surface and two sets of support columns mounted on the top of the connecting plate. An exhaust port, installed on the top of the gasification furnace body, consists of a limiting rod, a connecting pipe, an adsorption layer, a limiting hole, a filter screen, and a connecting ring. This invention overcomes the shortcomings of the prior art. By setting up an adsorption layer and a filter screen, the exhaust gas generated during combustion is discharged through the top exhaust port. The filter screen can block dust and impurities, reducing their escape. The adsorption layer, made of activated carbon, can adsorb and purify the exhaust gas, thereby reducing the impact on surrounding personnel and air pollution. Furthermore, the filter screen can be removed for cleaning and the activated carbon can be removed and replaced through the cooperation of the limiting rod and limiting hole, facilitating operation.

[0003] The inventors believe that feeding biomass into the gasifier body via a screw conveyor for thermal gasification results in uneven dispersion of the biomass upon entering the gasifier, thus affecting the degree of thermal gasification. Furthermore, filtering the generated gas through an adsorption layer and filter screen cannot effectively remove tar from the flue gas. Therefore, a biomass gasifier is needed. Utility Model Content

[0004] The purpose of this invention is to provide a biomass gasification furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a biomass gasification furnace, comprising a gasification furnace body, a feeding pipe and a gas supply pipe fixedly connected to the inner wall of the gasification furnace body, a gas supply cylinder fixedly connected to the inner bottom wall of the gasification furnace body, a material discharge cylinder slidably connected to the inner wall of the gasification furnace body, a plurality of discharge holes opened on the inner bottom wall of the material discharge cylinder, a plurality of driving rods fixedly connected to the surface of the material discharge cylinder, the top ends of the plurality of driving rods being fixedly connected to the same connecting plate, and a shaking oil removal mechanism installed on the upper surface of the gasification furnace body.

[0006] Preferably, the shaking oil removal mechanism includes a fixed shaft fixedly connected to the upper surface of the gasifier body, a plurality of support rods fixedly connected to the surface of the fixed shaft, a common mounting plate fixedly connected to the surface of the plurality of support rods, and a geared motor fixedly connected to the upper surface of the mounting plate.

[0007] Preferably, the output end of the geared motor passes through the lower surface of the mounting plate and is fixedly connected to a rotating disk. The surface of the rotating disk is provided with a wave groove. A ball head is fixedly connected to the surface of the connecting plate. The ball head is installed inside the wave groove and is adapted to the inner wall of the wave groove.

[0008] Preferably, a support plate is fixedly connected to the surface of the gasifier body, a purification cylinder is fixedly connected to the inner wall of the support plate, and an electric insulator is fixedly connected to the upper surface of the purification cylinder.

[0009] Preferably, an exhaust pipe is fixedly connected to the inner top wall of the purification cylinder, a guide plate is fixedly connected to the inner wall of the purification cylinder, an integrated plate and a discharge needle are fixedly connected to the inner wall of the purification cylinder, the diameter of the discharge needle is smaller than the inner diameter of the integrated plate, and the discharge needle is installed inside the integrated plate.

[0010] Preferably, an oil drain pipe is fixedly connected to the inner bottom wall of the purification cylinder, and a valve is installed on the surface of the oil drain pipe.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the ball head moves up and down under the action of the wave groove, causing the connecting plate and the discharge cylinder to bounce up and down. The material entering the discharge cylinder can be discharged more evenly through the discharge cylinder for high-temperature gasification. After the gas enters the purification cylinder, the discharge needle and the integrated plate will release negative ions and positive ions respectively, so that the air forms an electric field. The air passing through the electric field will carry negative ions and be attracted by the positively charged integrated plate. When the attached impurities exceed the adhesion of the integrated plate, they will slide down to the bottom of the purification cylinder due to gravity and accumulate. The advantage of this is that the biomass material is more evenly gasified during feeding, and the tar in the gas can be treated to meet the qualified standards. Attached Figure Description

[0023] By setting multiple support rods 12, installing support mounting plates 11, and setting a reduction motor 8, the rotating disk 13 is driven to rotate.

[0024] Preferably, the output end of the geared motor 8 passes through the lower surface of the mounting plate 11 and is fixedly connected to a rotating disk 13.

The ball head 10 is installed inside the wave groove 14 and is adapted to the inner wall of the wave groove 14.

[0025] By setting the wave groove 14, the ball head 10 in contact with it is driven to move up and down, which in turn drives the connecting plate 6 to move up and down reciprocally.
