Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and more specifically, to a dual-layer fuel supply atomizer. Background Technology

[0002] A nebulizer is used to atomize test solutions. It is a crucial component of an atomization system, and its performance significantly impacts the precision of measurements and reduces chemical interference. Therefore, nebulizers are required to produce stable sprays, fine and uniform droplets, and high atomization efficiency.

[0003] Currently, all atomizers on the market are single-layer fuel supply atomizing nozzles.

[0004] Although this type of atomizer is currently the most widely used, it still has the following problems during use:

[0005] (1) The connection method of the atomizer nozzle is mostly threaded rotation connection. After long-term use and exposure to air, it is easy to rust, making the later installation, replacement and disassembly process too cumbersome.

[0006] (2) The connection method of the atomizer nozzle is prone to poor airtightness during use, resulting in a certain amount of fuel leakage;

[0007] (3) All atomizers are single-layer fuel supply atomizing nozzles. During the process of changing combustion load, the fuel atomization effect is unstable, the adaptability is poor, the combustion is incomplete, and the flue gas composition is not easy to meet the standards. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the present invention aims to provide a double-layer fuel supply atomizer that prevents the threads from rusting and becoming difficult to replace, maintains the airtightness of the internal and external fuel in the inner and outer oil pipes, reduces fuel leakage, and ensures stable fuel atomization, good adaptability, and complete combustion.

[0012] Several fixing posts are fixed on one side of the nozzle; several arc-shaped slots are opened on the periphery of the fixing posts; the fixing posts are inserted into the insertion holes; the arc-shaped slots are engaged with the arc-shaped hook plates.

[0013] The present invention is further configured such that two symmetrical first fixing holes are provided on the peripheral side of the atomizing medium conduit.

[0014] The fixing component includes a fixing disc; one side of the fixing disc is connected to an outer ring rubber sleeve in a circumferential array; one side of the fixing disc is connected to an inner ring rubber sleeve in a circumferential array; a fixing sleeve is connected to the center of one side of the fixing disc; the inner wall of the fixing sleeve is fitted with the outer wall of the atomizing medium conduit.

[0015] The fixed sleeve has a second fixing hole on its peripheral side.

[0016] The present invention is further configured such that: an external fuel ring pipe is connected inside the distributor; an internal fuel ring pipe is connected inside the distributor; a central through pipe is connected to one side of the distributor; and the inner wall of the central through pipe is sleeved with the outer wall of the fixed sleeve.

[0017] The present invention is further configured such that: the outer fuel ring pipe has an external fuel inlet pipe arranged in a circular pattern on its circumferential side; the inner fuel ring pipe has an internal fuel inlet pipe arranged in a circular pattern on its circumferential side; the outer wall of the external fuel inlet pipe is sleeved with the inner wall of the outer ring rubber sleeve; the outer wall of the internal fuel inlet pipe is sleeved with the inner wall of the inner ring rubber sleeve.

[0018] The distributor has two symmetrical side baffles fixed on one side; fasteners are threadedly rotatably connected to one side of each of the two side baffles; the fasteners are fixedly connected to the first fixing hole; and the fasteners are fixedly connected to the second fixing hole.

[0019] The present invention is further configured such that: one end of the inner and outer oil pipes is provided with an internal oil inlet hole; one end of the inner and outer oil pipes is provided with an external oil inlet hole arranged in a circular pattern; the outer wall of the inner ring rubber sleeve is sleeved and fitted with the inner wall of the internal oil inlet hole; the outer wall of the outer ring rubber sleeve is sleeved and fitted with the inner wall of the external oil inlet hole.

[0020] The other end of the inner and outer oil pipes is arranged in a circular array and connected to an external oil outlet pipe; the other end of the inner and outer oil pipes is arranged in a circular array and connected to an internal oil outlet pipe.

[0021] The present invention is further configured such that: a circular slot is provided through one side of the distributor; an external oil pipe perforation is provided in a circumferential array at the bottom of the circular slot; and an internal oil pipe perforation is provided in a circumferential array at the bottom of the circular slot.

[0022] The circular slot is fitted with the other end of the inner and outer oil pipes; the outer oil pipe perforation is fitted with the outer oil outlet pipe; the inner oil pipe perforation is fitted with the inner oil outlet pipe.

[0023] The present invention is further configured such that one end of the atomizing medium conduit is fixed with an annular rail.

[0024] The nozzle is equipped with an internal mist nozzle; one end of the internal mist nozzle has an annular groove; the annular groove is engaged with an annular rail.

[0025] The present invention is further configured such that: the mist nozzle has a Y-shaped structure; the inner mist nozzle is provided with an inner oil injection hole, an outer oil injection hole, an atomizing medium injection hole and an atomizing hole arranged at a certain angle.

[0026] The present invention has the following beneficial effects:

[0027] 1. This invention allows the arc-shaped hook plate to rotate inside the hinge seat by moving it until the hooked end of the arc-shaped hook plate aligns with the arc-shaped slot on the side of the fixed column. After releasing the arc-shaped hook plate, the elastic force of the hinge spring causes the hooked end of the arc-shaped hook plate to engage with the arc-shaped slot, replacing the original threaded rotation connection of the nozzle. This simplifies the installation and disassembly process of the nozzle and prevents the threads from rusting and becoming difficult to replace.

[0028] 2. This invention sets the outer and inner rubber sleeves to a shape that is wider at the top and narrower at the bottom, so that the outer oil inlet pipe passing through the inner wall of the outer and inner rubber sleeves fits tightly against the outer wall of the inner oil inlet pipe. At the same time, the annular groove at one end of the inner mist nozzle is engaged with the annular rail fixed at one end of the atomizing medium conduit, and an internal sealing gasket is placed inside the annular groove to maintain the sealing of the other end of the atomizing medium conduit. This maintains the airtightness of the internal fuel and external fuel entering the inner and outer oil pipes, reducing the occurrence of fuel leakage.

[0029] 3. This invention introduces an atomizing medium into the atomizing medium conduit, allowing the atomizing medium in the Y-shaped internal atomizing nozzle to directly impact the fuel oil flow in the inner and outer oil pipes at a certain angle. This causes the fuel oil supplied by the inner and outer oil pipes to be atomized through the atomizing holes, achieving stable fuel atomization, good adaptability, and complete combustion. It is also well-suited for furnaces with high requirements for flue gas O2 and CO levels.

[0030] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0061] One specific application of this embodiment is:

[0062] The atomizing medium conduit 1 is passed through the inner wall of the fixed sleeve 205. Then, the inner wall of the central through-tube 303 is fitted onto the outer wall of the fixed sleeve 205.
