[0002] With industrial development, generator sets are widely used in various places, such as factories, construction sites, and data centers. Diesel generator sets are power generation devices that use diesel fuel as the main fuel. They are mechanical devices that use a diesel engine as the prime mover to drive a generator to generate electricity, converting kinetic energy into electrical energy and heat energy.

The spark-extinguishing disc base 5 is connected to the air intake side of the air intake pipe 3. See attached diagram for details. Figure 2 As shown, the lower part of the spark extinguishing disc base 5 is fixedly installed to the upper part of the silencer base 1 by bolts, and the closed top cover 6 is fixedly installed to the upper open side of the spark extinguishing disc base 5 by bolts. In order to eliminate sparks, an inner diffusion ring seat 9 and an outer shielding ring seat 10 are provided on the upper part of the spark extinguishing disc base 5, as shown in the attached figure. Figure 3As shown, both the inner diffuser ring seat 9 and the outer shielding ring seat 10 are annular. The inner diffuser ring seat 9 is fixedly installed on the inner top ring side of the spark extinguishing disc seat 5. To facilitate the diffusion and flow of exhaust gas, air guide holes 11 are evenly provided through the periphery of the inner diffuser ring seat 9. Three outer shielding ring seats 10 are provided, and they are fixedly installed on the outer top ring side of the spark extinguishing disc seat 5. The three outer shielding ring seats 10 are arranged in a ring shape and sequentially arranged on the outer side of the inner diffuser ring seat 9. In order to achieve the flow of exhaust gas and the elimination of sparks, rectangular slots 12 are staggered on the periphery of adjacent sets of outer shielding ring seats 10. The rectangular slots 12 are evenly provided in a circular shape on the outer periphery of the outer shielding ring seats 10. The upper rectangular slots 12 are arranged in an alternating pattern, and a ring-shaped spark extinguishing structure is adopted. A spark extinguishing disc seat 5 is provided on the side of the air inlet pipe 3 of the silencer. The upper part of the spark extinguishing disc seat 5 is sealed by a closed top cover 6, and an inner diffuser ring seat 9 and an outer shielding ring seat 10 are provided in the middle. The outer shielding ring seats 10 are arranged in a ring shape and are arranged on the outside of the inner diffuser ring seat 9.

[0022] The air duct 8 is supported and installed on the upper inner side of the muffler base 1 via the muffler slot 7, as detailed in the attached diagram. Figure 4 As shown, to support the installation of the muffler base 7, a support ring seat 16 is fixedly installed on the inner side of the muffler base 1. A support side seat 13 is fixedly installed on the lower part of the muffler base 7. The upper part of the muffler base 1 is fixedly installed to the top seat side of the muffler base 1 by bolts.

The connecting slot hole 14 is evenly opened in a circular shape on the upper circumference of the air guide pipe 8, and a side overflow type obstruction is adopted. The noise reduction structure utilizes the silencing groove 7 located on the upper inner side of the silencing cylinder base 1 to guide the flow of exhaust gas after the spark extinguishing. The silencing groove 7 has multiple sets of air guiding pipes 8 in the middle and connecting slots 14 on the periphery of the air guiding pipes 8.

The peripheral diffusion holes 15 are evenly and circumferentially opened on the outer periphery of the silencing groove 7.
[0023] Working principle or structural principle: During operation, the muffler's intake pipe 3 is connected to the exhaust side of the generator set. When generating electricity, the exhaust gas produced by the generator set enters the spark extinguishing disc seat 5 through the intake pipe 3. Within the spark extinguishing disc seat 5, the exhaust gas is diffused and guided by the inner diffuser ring seat 9. Then, the exhaust gas enters the innermost outer shielding ring seat 10 and enters the outermost outer shielding ring seat 10 through the rectangular slots 12 on its periphery. The rectangular slots 12 on the upper parts of adjacent sets of outer shielding ring seats 10 are staggered. During operation... The staggered shielding of the outer shielding ring seat 10 can block and block incompletely burned carbon particles, achieving efficient elimination of sparks and initial reduction of exhaust gas velocity. Then, the exhaust gas diffuses upward, enters through the lower opening side of the gas guide pipe 8, and overflows and diffuses out through the connecting slot 14 on its periphery. During this process, the exhaust gas velocity is greatly reduced, effectively suppressing and weakening the generator noise. Afterward, the exhaust gas diffuses through the peripheral diffusion holes 15 on the periphery of the silencer seat 7 and is discharged to the outside through the exhaust end pipe 4, completing the exhaust gas silencing work.
[0024] In summary, this muffler adopts a ring-shaped spark extinguishing structure. A spark extinguishing disc seat 5 is installed on the side of the muffler's inlet pipe 3. The upper part of the spark extinguishing disc seat 5 is sealed by a top cover 6, and an inner diffuser ring seat 9 and an outer shielding ring seat 10 are installed in the middle. The outer shielding ring seats 10 are arranged in a ring shape outside the inner diffuser ring seats 9. Rectangular slots 12 are staggered on the upper parts of adjacent sets of outer shielding ring seats 10. During operation, the staggered shielding of the outer shielding ring seats 10 can block and prevent incompletely burned carbon particles, achieving efficient spark elimination and preventing sparks from entering the muffler structure. The structure is simple and reliable, which helps improve the stability and safety of the device. It adopts a side overflow type flow-blocking and noise reduction structure. The silencing groove seat 7 set on the upper inner side of the silencing cylinder seat 1 guides the flow of exhaust gas after the spark extinguishing. The middle of the silencing groove seat 7 is provided with multiple sets of air guiding pipes 8 and the periphery of the air guiding pipes 8 is provided with connecting slots 14. The flow-blocking and conduction of the air guiding pipes 8 can effectively suppress and reduce the noise of the generator set. In addition, both the silencing groove seat 7 and the spark extinguishing disc seat 5 adopt a split installation structure, which is convenient for disassembly and assembly, and improves the convenience of device maintenance and repair.
