Description

Technical Field

[0001] This utility model relates to the field of biomass pellet gasification furnace technology, specifically to a detachable biomass pellet gasification furnace core. Background Technology

[0002] A biomass pellet gasifier is a device that uses biomass pellet fuel for gasification and combustion to obtain thermal energy. The gasifier core, as its core component, plays a crucial role in the gasifier's performance. Existing biomass pellet gasifier cores have some shortcomings. For example, some core structures are poorly designed, leading to incomplete combustion of biomass pellets and the emission of harmful gases such as carbon monoxide, wasting energy and polluting the environment. Furthermore, some core components are not easily disassembled, making operation inconvenient when the core malfunctions or requires maintenance, increasing repair and time costs. Therefore, it is necessary to design a core that allows for complete combustion of biomass pellets while facilitating the disassembly and maintenance of its components. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detachable biomass pellet gasifier core with reasonable structural design, complete combustion, easy disassembly and maintenance, and strong practicality.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable biomass pellet gasifier core, comprising an outer cylinder, an inner cylinder, a fire collecting cylinder, an ash removal mechanism, and an ignition rod mounting hole. The inner cylinder is installed inside the outer cylinder via a first flange, the fire collecting cylinder is installed inside the inner cylinder, the ash removal mechanism is installed below the inner cylinder, and an ignition rod mounting hole is installed on the bottom side of the fire collecting cylinder, with an ignition rod installed in the ignition rod mounting hole.

Air inlets are provided on both sides of the upper end of the biomass pellet combustion chamber, and the air inlets are embedded and connected to the pipe openings of the air inlets on the outer side of the inner cylinder. An ash discharge structure is provided below the biomass pellet combustion chamber.

[0006] Preferably, the ash discharge structure is a conical cylinder, with the small end of the ash discharge structure connected to the ash discharge mechanism, and the large end of the ash discharge structure used to support particulate fuel and discharge ash.

[0007] An ash discharge pipe is also provided on the outside of the air duct, and the bottom of the ash discharge pipe is connected to the drawer-type ash box in the ash discharge mechanism.

[0008] Preferably, the side of the fire-collecting tube is also provided with an air guide pipe. The lower end of the air guide pipe is a through hole with an electric valve to control the air intake and facilitate air entry. The upper end of the air guide pipe is connected to the combustion chamber. A fuel filling hole is provided in the fire-collecting tube section between the air guide pipes.

[0009] Preferably, the end of the air guide tube has a spiral nozzle structure.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0016] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Reference Figure 1 The specific embodiment adopts the following technical solution: a detachable biomass pellet gasifier core, including an outer cylinder 1, an inner cylinder 2, a fire collection cylinder 3, an ash removal mechanism 4, and an ignition rod mounting hole 5. The inner cylinder 2 is installed inside the outer cylinder 1 through a first flange 21. The fire collection cylinder 3 is provided inside the inner cylinder 2. The ash removal mechanism 4 is provided below the inner cylinder 2. The bottom side of the fire collection cylinder 3 is equipped with an ignition rod mounting hole 5, and an ignition rod 51 is installed in the ignition rod mounting hole 5.

[0019] It is worth noting that the aforementioned combustion chamber 3 includes a gasification combustion chamber 31, a biomass pellet combustion chamber 32, and an ash discharge structure 33. A support plate 22 is provided at the upper end of the biomass pellet combustion chamber 32, on which the gasification combustion chamber 31, inserted through the furnace core opening, is placed. The lower part of the biomass pellet combustion chamber 32 is welded to the inner wall of the inner cylinder 2. Air inlets are provided on both sides of the upper end of the biomass pellet combustion chamber 32, and these inlets are embedded and connected to the inlets of the air inlets on the outer side of the inner cylinder 2. Air is supplied to the biomass pellet combustion chamber through the air inlets, allowing the biomass pellet fuel to come into sufficient contact with air, thereby achieving complete combustion of the gasified fuel. An ash discharge structure 33 is provided below the biomass pellet combustion chamber 32. Since carbon monoxide gas may be produced due to incomplete combustion during the combustion process of biomass pellets, the gasification combustion chamber can completely burn this carbon monoxide gas, improving energy utilization and reducing harmful gas emissions.

[0020] It is worth noting that the ash discharge structure 33 is a conical cylinder. The upper end of the ash discharge structure 33 is installed below the biomass pellet combustion chamber 32 via a second flange 331. The small-hole end of the ash discharge structure 33 is connected to the ash discharge mechanism 4, and the large-hole end of the ash discharge structure 33 is used to support the pellet fuel and discharge the ash. When the ash formed after the biomass pellet fuel combustion accumulates to a certain extent, it can be discharged from the furnace core through the ash discharge mechanism.

[0021] It is worth noting that a gas guide pipe 6 is also provided on the side of the fire collection tube 3. The lower end of the gas guide pipe 6 is a through hole with an electric valve, which can control the air intake and facilitate air entry. The upper end of the gas guide pipe 6 is connected to the gasification combustion chamber 31. A fuel filling hole is provided at the lower part of the fire collection tube 3 between the gas guide pipes 6.

[0022] It is worth noting that the end of the air guide pipe 6 is a spiral nozzle structure, which forms a swirling airflow and enhances the mixing efficiency of the gas with the high-temperature zone.

[0023] It is worth noting that an ash discharge pipe 7 is also provided on the outside of the air duct 6, and the bottom of the ash discharge pipe 7 is connected to the drawer-type ash box 41 in the ash discharge mechanism 4.

[0024] Furthermore, the gasification combustion chamber 31 is equipped with layered guide vanes, forming a multi-stage combustion chamber. This forces the gas to remain in the high-temperature zone for a longer period, promoting the secondary combustion of harmful gases such as CO. The guide vanes are made of high-temperature resistant alloy material and coated with a catalytic coating (such as an iron oxide-copper oxide composite material) to accelerate the CO oxidation reaction and reduce pollutant emissions.

[0025] In this specific embodiment, air is supplied to the biomass pellet combustion chamber 32 through the air inlet pipe. The air enters the biomass pellet combustion chamber 32 through the air inlet, providing sufficient oxygen for the combustion of biomass pellet fuel. The ash discharge structure 33 is a conical cylinder, with its small end connected to the ash discharge mechanism 4, and its large end supporting the pellet fuel and discharging the ash. After the biomass pellet fuel burns in the biomass pellet combustion chamber 32, the ash gradually accumulates on the ash discharge structure 33, and is discharged from the furnace core by the ash discharge mechanism 4, keeping the inside of the furnace core clean. A gasification combustion chamber 31 is placed on the support plate 22 at the upper end of the biomass pellet combustion chamber 32, and the gasification combustion chamber 31 is inserted through the furnace core opening. Unburned gases such as carbon monoxide generated during the biomass pellet combustion process rise into the gasification combustion chamber 31 and continue to burn within it, allowing for more complete utilization of the fuel. After combustion in the gasification combustion chamber 31, the ash enters the drawer-type ash box 41 inside the ash discharge mechanism 4 through the ash drop pipe 7 for collection. The disassembly methods of each component of the fire collection tube 3 are as follows: When it is necessary to clean or repair the gasification combustion chamber 31, it can be directly removed from the support plate 22; if it is necessary to maintain the air inlet pipe, the air inlet pipe port can be pulled out from the air inlet hole; for the connection between the ash discharge structure 33 and the ash discharge mechanism 4, it can be separated by the corresponding disassembly method (such as unscrewing the bolts) so that the ash discharge mechanism 4 and the ash discharge structure 33 can be inspected and cleaned.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
