Abstract
Description
Technical Field
[0001] This utility model relates to the field of burner technology, and in particular to a high-efficiency combustion device for burners. Background Technology
[0002] A burner is a device used to mix fuel (such as gas, liquid fuel, or solid fuel) and oxygen to produce a combustion reaction. This device mixes fuel and oxygen and ignites them under appropriate conditions to achieve the combustion process. A burner typically includes a gas outlet, an ignition device, and a regulation and control system.
[0003] A single nozzle may limit the full mixing of gas and air, resulting in uneven combustion, unsatisfactory combustion effect, and affecting combustion efficiency and thermal efficiency. To address this, we propose a high-efficiency combustion device for burners. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a high-efficiency combustion device for burners.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency combustion device for a burner, comprising a shell, a filter, a connecting cylinder, and an inner shell. A filter cylinder is disposed below the shell, and a connecting cylinder is disposed at the lower end of the filter cylinder. An inner shell is disposed inside the shell. A constriction is disposed at the upper end of the filter, penetrating the inner shell. A diverter pipe arranged in a ring array is connected to the upper end of the constriction pipe. A vortex generator is disposed at the upper end of each diverter pipe. An air inlet hole arranged in a ring array and located at the lower end of the vortex generator is opened inside the upper end of the inner shell. An injection nozzle is disposed at the upper end of the inner shell.
[0006] Preferably, an air inlet is provided at the upper end of the outer shell. External air enters the space between the outer shell and the inner shell through the air inlet.
[0007] Preferably, a universal joint is provided at the lower end of the docking cylinder. The universal joint transports the gas and ensures the docking cylinder can bend and move freely during use, allowing for effective docking between the cylinder and the filter.
[0008] Preferably, the filter contains a filter cartridge, and the inner wall of the connecting cylinder is provided with a support ring located at the lower end of the filter cartridge. A flow guide bucket is located at the lower end of the support ring. The support ring inside the filter cartridge supports the lower side of the filter cartridge, and the flow guide bucket guides the transported gas flow.
[0009] Preferably, the filter has a top ring on its upper inner wall, and the filter cartridge has a fitting ring at its upper end. The top ring has an annular fitting groove at its lower end, and the fitting ring engages with the groove. An annular sealing ring is provided on the inner wall of the groove. After the fitting ring and groove at the upper end of the filter cartridge engage, the sealing ring improves the sealing at the engagement point, and the top ring provides support for the upper end of the filter cartridge.
[0010] Preferably, the upper end of the filter cartridge is provided with a guide bucket corresponding to the opening of the top ring. The guide bucket guides the gas passing through the filter cartridge.
[0011] Preferably, a flow guide is installed between the filter and the constriction, and the inner diameter of the flow guide gradually decreases from bottom to top. The supplied gas enters the constriction through the flow guide.
[0012] Preferably, a side ring is fitted onto the lower outer wall of the filter, and a threaded sleeve is provided on the outer wall of the docking cylinder for threaded installation with the outer wall of the filter. A sealing gasket is provided on the upper end of the side ring. The docking cylinder is threadedly installed with the filter via the threaded sleeve, and the upper end of the threaded sleeve is supported by the side ring. The sealing gasket improves the sealing performance at the contact point between the threaded sleeve and the side ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a universal tube to transport gas. When the gas passes through the constriction, the diameter of the constriction decreases, the gas passing through the constriction is pressurized, and it is diverted into the interior of the distribution pipes arranged in a ring array. It is then output through a vortex generator. The gas passing through the vortex generator causes the rotating components inside the vortex generator to rotate, generating a rotating airflow, which promotes better mixing of air and gas and improves mixing efficiency. At the same time, the output ports of multiple distribution pipes output gas, increasing the combustion area. The layout of multiple nozzles can make the gas and air mix better, achieving high-efficiency combustion of the burner. Attached Figure Description

[0020] Figure label: Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-5 As shown, the present invention proposes a high-efficiency combustion device for a burner, comprising an outer shell 1, a filter 2, a connecting cylinder 3, and an inner shell 7. A filter cylinder 17 is disposed below the outer shell 1, and a connecting cylinder 3 is disposed at the lower end of the filter cylinder 17. An inner shell 7 is disposed inside the outer shell 1. A constriction 5 penetrating the inner shell 7 is disposed at the upper end of the filter 2. A diverter pipe 11 arranged in a ring array is connected to the upper end of the constriction 5. A vortex generator 9 is disposed at the upper end of each diverter pipe 11. An air inlet 10 arranged in a ring array and located at the lower end of the vortex generator 9 is opened inside the upper end of the inner shell 7. An injection nozzle 8 is disposed at the upper end of the inner shell 7.
[0023] An air inlet 6 is provided at the upper end of the outer casing 1;
[0024] A universal joint 4 is provided at the lower end of the docking cylinder 3;
[0025] Based on the implementation steps of Example 1: Gas is delivered to the inside of the docking cylinder 3 through the universal tube 4. When passing through the constriction 5, the gas is pressurized, causing the gas to be diverted into the diversion pipe 11. The output gas is rotated by the vortex generator 9. Outside air enters the air inlet 10 through the air inlet 6 and mixes with the gas through the air inlet 10. It is worth noting that an igniter is set at the nozzle 8 to ignite the gas for combustion in the burner. During the combustion process, the gas is diverted and mixed with more oxygen in the air. A burner with a single nozzle may cause uneven combustion, affecting combustion efficiency and thermal efficiency, and limiting the full mixing of gas and air. By arranging multiple nozzles neatly, the combustion area can be increased. The layout of multiple nozzles can make the gas and air mix better. The ring array of nozzles can reduce combustion unevenness and stabilize the combustion process. Combustion through multiple nozzles can improve heat conversion efficiency and improve combustion effect.
[0026] like Figures 1-5 As shown, compared with Embodiment 1, the high-efficiency combustion device for burners proposed in this utility model further includes: a filter cartridge 17 is provided inside the filter 2, a support ring 18 located at the lower end of the filter cartridge 17 is provided on the inner wall of the connecting cylinder 3, and a flow guide hopper 2 19 is provided at the lower end of the support ring 18.
[0027] A top ring 12 is provided on the inner wall of the upper end of the filter 2, and a fitting ring 15 is provided on the upper end of the filter cartridge 17. A ring-shaped fitting groove 20 is opened inside the lower end of the top ring 12. The fitting ring 15 is connected to the inside of the fitting groove 20. A ring-shaped sealing ring 21 is provided on the inner wall of the fitting groove 20.
[0028] The upper end of the filter cartridge 17 is provided with a guide bucket 16 corresponding to the opening of the top ring 12;
[0029] A flow guide shroud 13 is installed between the filter 2 and the constriction 5, and the internal diameter of the flow guide shroud 13 gradually decreases from bottom to top;
[0030] A side ring 22 is fitted onto the lower outer wall of the filter 2, and a threaded sleeve 14 is provided on the outer wall of the connecting cylinder 3 to be threaded onto the outer wall of the filter 2. A sealing gasket is provided on the upper end of the side ring 22.
[0031] In this embodiment, the gas is welded to the filter cartridge 17. When the gas passes through the filter cartridge 17, it may contain impurities, which may come from the gas collection and transportation process. By filtering the impurities, unnecessary impurities are removed, making the gas purer, thereby improving combustion efficiency and reducing ineffective energy consumption. The connecting cylinder 3 and the filter 2 are threaded together and can be disassembled. Regular cleaning or replacement of the filter cartridge 17 can effectively reduce the failure rate of the equipment during operation, improve safety, and help reduce the exhaust gas emissions generated during combustion, which meets environmental protection requirements. The design of the filter cartridge 17 is usually easy to disassemble and clean, which can simplify the maintenance process and improve the reliability of the equipment.
[0032] The above specific embodiments are merely several preferred embodiments of this utility model.
