Description

Technical Field

[0001] This utility model relates to the field of generator set muffler technology, specifically a generator set muffler with an anti-clogging structure. Background Technology

[0002] With the continuous growth of electricity demand, generator sets are being used more and more widely. However, generator sets generate considerable noise during operation, which not only causes serious noise pollution to the surrounding environment but may also damage the hearing of operators. As an important supporting device for generator sets, the main function of a silencer is to reduce the noise generated during operation, providing noise reduction protection for the plant environment and personnel.

[0003] When in operation, the muffler is installed on the exhaust side of the generator set. Since the exhaust gas emitted by the generator contains a large number of dust particles, these dust particles directly enter the muffler during operation. In order to achieve noise reduction, the muffler needs to be equipped with multiple sets of flow-blocking structures. During this process, dust particles are prone to adhere and accumulate inside the muffler, causing blockage of the internal channels, which in turn affects the noise reduction effect and may even lead to an increase in the back pressure of the generator set, affecting the normal operation of the unit. Therefore, a muffler for generator sets with an anti-blockage structure is proposed. Utility Model Content

The filter sleeve 4 is installed on the outside of the side air inlet connecting holes 9 at the rear part of the air inlet end pipe 3. The filter sleeve 4 can filter and remove the dust particles entering the exhaust gas, preventing dust from entering the rear noise reduction structure, which is conducive to improving the working stability of the device. The filter sleeve 4 is supported and installed by the air inlet end pipe 3 with a split and detachable structure, which is convenient for disassembly and assembly, and improves the convenience of cleaning and maintenance of the filter sleeve 4. In order to facilitate the fixed installation of the filter sleeve 4, the front end seat side of the filter sleeve 4 is fixedly installed to the rear part of the mounting end seat by bolts. In order to improve the heat dissipation efficiency of the filter sleeve seat 1, heat dissipation fins 10 are evenly fixedly installed on the outer periphery of the filter sleeve seat 1.

[0022] The silencer cover 5 is installed at the front of the inner cavity of the silencer base 2 to restrict the flow of exhaust gas, as shown in the attached diagram. Figure 3 As shown, the silencer hood 5 is a hollow cylindrical base. The front end of the silencer hood 5 is fixedly connected to the rear end pipe side of the filter cartridge base 1. The rear end of the silencer hood 5 extends into and is inserted into the front side of the silencer cartridge base 2. To facilitate the lateral flow of exhaust gas, diffuser holes are evenly provided around the periphery of the silencer hood 5. The inner partition seat 8 is installed in the middle of the inner cavity of the silencer cartridge base 2.

Multiple exhaust connecting holes 12 are provided. Several exhaust connecting holes 12 are evenly distributed in a circular shape on the front outer periphery of the exhaust pipe 7. A multi-stage flow-blocking noise reduction structure is adopted. The intake pipe 3, the muffler cover 5 and the exhaust pipe 7 all adopt a side overflow connecting working structure. With the separation and flow blocking of the inner partition seat 8 in the middle of the muffler seat 2 and the inner connecting and guiding of the inner connecting pipe 6, the exhaust gas velocity can be stably weakened and reduced. Multiple combinations can achieve effective noise reduction on the exhaust side of the generator set, and have a better noise reduction effect compared with similar noise reduction equipment.

[0024] Working principle or structural principle: During operation, the device is installed and supported by a bracket, and the inlet pipe 3 is connected to the exhaust side of the generator set. When the generator set is working, the exhaust gas enters the filter cartridge seat 1 through the inlet pipe 3. Inside the inlet pipe 3, the exhaust gas diffuses outward through the inlet connecting holes 9 on its periphery. During this process, the filter sleeve 4 filters and removes the dust particles in the exhaust gas. While filtering the dust particles in the exhaust gas, it also achieves preliminary flow obstruction and speed reduction of the exhaust gas. At the same time, the heat dissipation fins 1 set on the outside of the filter cartridge seat 1 further enhance the cooling effect. 0 can accelerate the heat dissipation and cooling of the filter cartridge seat 1, which is conducive to the reduction of exhaust gas temperature. Then, the exhaust gas enters the rear muffler cover 5 through the inner cavity. After being diffused and diverted by the muffler cover 5, it enters the cavity formed by the inner partition seat 8 and the inner tube mounting seat 11 from the rear. Then, the exhaust gas is guided through the inner connecting pipe 6 and diffused into the exhaust end pipe 7 through the exhaust connecting hole 12. Then, it is discharged to the outside from the exhaust end pipe 7 side. In the process, the combined effect of multiple flow-blocking structures can effectively reduce the noise on the exhaust side of the generator set, thus completing the noise reduction work. During cleaning and maintenance, remove the filter cartridge seat 1 by unscrewing, then remove the bolts on the side of the air inlet pipe 3 and remove the air inlet pipe 3 together with the filter sleeve 4. After that, remove and clean or replace the filter sleeve 4 outside the air inlet pipe 3. After that, reset the filter cartridge seat 1 and reinstall it to complete the cleaning and maintenance of the device.

[0025] In summary, this silencer adopts a pre-filtered anti-clogging working structure. A filter sleeve 4 is installed outside the lateral air inlet communication hole 9 at the rear of the air inlet pipe 3. The filter sleeve 4 can filter and remove the dust particles entering the exhaust gas, preventing dust from entering the rear noise reduction structure, which is conducive to improving the stability of the device. Furthermore, the filter sleeve 4 is supported and installed by the detachable air inlet pipe 3, which is convenient for disassembly and assembly, and improves the convenience of cleaning and maintenance of the filter sleeve 4. It adopts a multi-stage flow-blocking noise reduction structure. The air inlet pipe 3, the silencer cover 5, and the exhaust pipe 7 all adopt a lateral overflow communication working structure. With the separation and flow blocking of the inner partition seat 8 in the middle of the silencer base 2 and the internal communication and flow guiding of the inner connecting pipe 6, the exhaust gas velocity can be stably weakened and reduced. Multiple combinations can effectively reduce the noise on the exhaust side of the generator set, and have a better noise reduction effect compared with similar silencers.
