However, the exhaust system of existing silent diesel generators is not equipped with a device to treat the exhaust gases, so harmful exhaust fumes are directly emitted into the external environment, which poses a certain risk to the health of workers and also pollutes the environment. Utility Model Content

The DPF control system is connected to the electrical control system of the unit to realize the start-up synchronization function. In this way, by using it in conjunction with the exhaust system assembly, it can treat harmful substances in the exhaust gas, thereby reducing harm to human health and environmental pollution.

[0011] By adopting the above technical solution and setting up mounting ears, an auxiliary installation function can be achieved.

[0012] Preferably, each of the two mounting ears has a corresponding identical insertion hole, each of the two insertion holes has a corresponding threaded post, and each of the two threaded posts is screwed with a corresponding nut.

[0016] Preferably, multiple positioning seats are fixedly installed on the periphery of the third bend component, and the first arc plate and the second arc plate are located above the multiple positioning seats.

[0017] By adopting the above technical solution and setting a positioning seat, the installation can be positioned and supported.

[0018] Preferably, each of the multiple positioning seats has a corresponding positioning groove on its top, and a corresponding positioning block is slidably installed in each of the multiple positioning grooves. The multiple positioning blocks are respectively fixedly installed at the bottom of the corresponding first arc plate and second arc plate.

An exhaust gas treatment mechanism, a dust prevention mechanism installed on the exhaust gas treatment mechanism, and a disassembly mechanism installed on the dust prevention mechanism are connected in series in the exhaust system assembly 5.

[0032] The exhaust gas treatment mechanism includes a straight pipe component 6 installed in the exhaust system assembly 5. The straight pipe component 6 is equipped with a hose component 7 and a fixed flange 10. One end of the hose component 7 is equipped with a first bend component 9.

A black smoke purifier DPF 14 is installed at one end of the second bend component 13. A third bend component 15 is connected to one end of the black smoke purifier DPF 14.

[0033] When in use, the DPF14 black smoke purifier is mainly used to capture particles in the exhaust gas to meet the emission requirements for particulate number (PN). The DPF14 black smoke purifier control system is connected to the electrical control system of the unit to realize the start-up synchronization function. In this way, by using it in conjunction with the exhaust system assembly 5, it can treat harmful substances in the exhaust smoke, thereby reducing harm to the human body and pollution to the environment.

[0034] Reference Figure 3-4 The dustproof mechanism includes a frame 16 mounted on the third bend component 15, and a filter screen 17 is provided inside the frame 16.

[0035] When in use, the filter screen 17 prevents external impurities from entering the equipment through the third bend component 15.

[0036] Reference Figure 4-5The disassembly and assembly mechanism includes a first arc plate 18 and a second arc plate 19 symmetrically mounted on the frame 16. Each side of the first arc plate 18 and the second arc plate 19 is fixedly equipped with a corresponding mounting ear 25. Each mounting ear 25 has a corresponding same insertion hole 26. Each insertion hole 26 has a corresponding threaded post 27. Each threaded post 27 is screwed with a corresponding nut 28. Each side of the frame 16 has a corresponding reinforcing hole 20. Each reinforcing hole 20 has a corresponding reinforcing post 21 slidably mounted in it.

[0039] The implementation principle of a silent diesel generator set with exhaust gas treatment in this application embodiment is as follows: During use, HC (hydrocarbon) emissions can be reduced through DOC12: unburned HC and lubricating oil HC in the exhaust gas are oxidized to H2O and CO2; NO is oxidized to NO2; NO2 oxidizes carbon particles captured by DPF to gaseous CO2. The black smoke purifier DPF14 is mainly used to capture particles in the exhaust gas to meet the emission requirements for particulate number (PN). The black smoke purifier DPF14 control system is connected to the electrical control system of the generator set to realize the start-up synchronization function.

[0040] The filter screen 17 prevents external impurities from entering the equipment through the third bend component 15. By splicing the first arc plate 18 and the second arc plate 19 onto the frame 16, inserting the threaded post 27 into the insertion hole 26, and rotating the nut 28, the two mounting ears 25 and the first arc plate 18 and the second arc plate 19 can be fixedly connected, thereby positioning and installing the frame 16 and the filter screen 17; thus facilitating later disassembly, cleaning, and maintenance.
