Description

Technical Field

[0001] This utility model belongs to the field of biomass gasification furnace tar recovery technology, and relates to a biomass gasification furnace tar utilization device. Background Technology

[0002] Existing biomass gasification furnaces have several drawbacks in treating the tar produced during biomass combustion. First, tar is generated due to incomplete combustion of biomass during gasification, and its complex chemical structure and high molecular weight make it difficult to utilize effectively. Second, the presence of tar contaminates downstream equipment, such as engines or gas turbines, reducing their operating efficiency and lifespan. Furthermore, the tar treatment and purification processes increase the complexity and cost of the biomass gasification system.

[0003] Conventional approaches include physical and chemical methods. Physical methods primarily promote secondary pyrolysis of tar by increasing the gasification temperature and extending the gasification time, but this method requires more energy and places high demands on the high-temperature resistance of the equipment. Chemical methods involve using catalysts to promote the pyrolysis or conversion of tar, but catalysts are prone to deactivation and are sensitive to impurities in the feedstock, requiring frequent replacement and maintenance.

[0004] The drawbacks of these conventional methods are that they either increase the system's energy consumption and cost or require additional maintenance. Furthermore, these methods often cannot completely eliminate the tar problem, leaving a certain amount of tar residue in the gasified gas. Therefore, there is an urgent need for a biomass gasification furnace tar utilization device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a biomass gasification furnace tar utilization device to solve the problems mentioned in the background technology.

[0006] This utility model is achieved through the following technical solution: a biomass gasification furnace tar utilization device, including: a burner inlet pipe and a guide pipe, wherein a set of covers for covering the outside of the burner inlet pipe is provided on the right side of the burner inlet pipe, and a set of funnels for recovering the tar inside the burner inlet pipe is provided at the lower right end of the burner inlet pipe.

[0007] The inside of the burner inlet tube is connected to the inside of the funnel. The upper right side of the funnel has an arc-shaped cross-section. The upper end of the funnel is sealed and fitted with the lower right side of the burner inlet tube. A set of horizontal tubes for conducting tar inside the burner inlet tube is provided on the lower right side of the funnel. The inside of the horizontal tubes is seamlessly connected to the bottom of the funnel, and the insides of the tubes are all interconnected.

[0008] In a preferred embodiment, a set of guide pipes for collecting tar is provided at the lower right end of the horizontal pipe. The guide pipes are arranged perpendicularly to the horizontal pipe and are internally interconnected.

[0009] In a preferred embodiment, the guide pipe, horizontal pipe, and funnel are all disposed inside the sealed casing. The guide pipe penetrates the upper end of the insulated furnace body and communicates with the interior of the insulated furnace chamber. A set of ball valves for controlling the flow of biomass combustion tar is provided inside the right side of the burner inlet pipe. In actual use, when the biomass gasifier is burning biomass materials, the tar is introduced into the burner inlet pipe through the upper end of the insulated furnace body for conduction. At the same time, when the insulated furnace body stops burning, the operator opens the ball valves and allows the tar to be conducted along the burner inlet pipe. Simultaneously, the tar flows back into the insulated furnace chamber through the funnel into the horizontal pipe and guide pipe. When the insulated furnace body burns biomass materials, the tar can provide a combustion-supporting effect on the biomass materials, thereby enabling their combustion and utilization.

[0010] In a preferred embodiment, the outer side of the cover is provided with a set of sealing covers for protecting the right side of the burner inlet pipe, and the lower end of the sealing covers is provided with a set of connecting flanges for connecting and fixing to the sealing covers.

[0011] In a preferred embodiment, a set of sealing covers II for thermal insulation connection to the upper end of the insulated furnace body is provided at the lower end of the connecting flange, and a set of connecting flanges II for connection and fixation to the upper end of the insulated furnace body is provided at the lower end of the sealing covers II.

[0012] In a preferred embodiment, the lower end of the second connecting flange is provided with an insulated furnace body for biomass gasification combustion, and the center of the front side of the second sealing cover is provided with an exhaust pipe for discharging the flue gas generated during the combustion process.

[0013] In a preferred embodiment, the exhaust pipe is provided with a set of control valves for controlling the flow rate of flue gas, and the lower front side of the insulated furnace body is provided with a set of gas conduits for introducing external combustion-supporting gas.

[0014] In a preferred embodiment, the insulated furnace body is equipped with an insulated furnace chamber for biomass gasification and combustion. The inner wall of the insulated furnace chamber is provided with several sets of internal heat conduction distribution pipes for uniform heat conduction. These internal heat conduction distribution pipes are evenly distributed in a spiral structure on the inner wall of the insulated furnace chamber. When the biomass material is burned inside the insulated furnace chamber, the inner wall of the furnace chamber integrates a network of multiple sets of spiral-configured internal heat conduction distribution pipes. Its topology is designed based on the principles of asymmetric fluid dynamics, constructing a gradient heat flow distribution field in three-dimensional space by expanding the heat conduction interface area and optimizing the curvature of the heat transfer path. This spiral flow guiding device effectively eliminates the thermodynamic heterogeneity of local overheated areas and low-temperature dead zones by strengthening the dynamic balance of circumferential heat flow, promoting isotropic temperature field characteristics within the combustion chamber, thereby enhancing the complete effect of the gas-solid two-phase reaction while maintaining combustion stability.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the biomass gasifier burns biomass materials, the tar is introduced into the burner inlet pipe through the upper end of the insulated furnace body for conduction. At the same time, when the insulated furnace body stops burning, the operator opens the ball valve and allows the tar to be conducted along the burner inlet pipe. Simultaneously, the tar flows back into the insulated furnace chamber through the funnel into the horizontal pipe and the guide pipe. When the insulated furnace body burns biomass materials, the tar can provide combustion assistance to the biomass materials, thereby enabling their combustion and utilization.

[0016] When biomass materials are burned inside an insulated furnace, the inner wall of the furnace integrates a network of multiple spiral-shaped internal heat conduction distribution pipes. Its topology is designed based on the principle of asymmetric fluid dynamics. By expanding the heat conduction interface area and optimizing the curvature of the heat transfer path, a gradient heat flow distribution field in three-dimensional space is constructed. This spiral flow guiding device effectively eliminates the thermodynamic heterogeneity of local overheated areas and low-temperature dead zones by strengthening the dynamic balance of circumferential heat flow, and promotes the isotropic characteristics of the temperature field in the combustion chamber. Thus, while maintaining combustion stability, it enhances the complete effect of gas-solid two-phase reaction. Attached Figure Description
