Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment devices, in particular to an anti-clogging particle trap which is easy to clean. Background Art

[0002] The diesel engine adopts pre-treatment technology, in-engine purification technology and end-of-pipe treatment technology. The end-of-pipe treatment technology mainly adopts a diesel oxidation catalyst (DOC) device for oxidizing exhaust hydrocarbons and carbon monoxide + a particulate matter trap (DPF) + a selective catalytic reduction NOx catalyst (SCR) device to achieve pollutant emission reduction of marine diesel engines. Among them, the DPF can capture tiny particles before they enter the atmosphere, which can reduce particulate matter emissions by 70%-90% and reduce pollution to the atmosphere. The process of filtering and oxidizing the collected exhaust gas and harmful particles in the DPF is called regeneration. When the DPF is blocked by the collected particles, the DPF can be unblocked through active regeneration or passive regeneration to avoid affecting the performance of the engine.

[0003] The DPF carrier collects PM (particulate matter) in the exhaust gas through filtration and storage, and burns and treats it regularly. During the regular combustion and cleaning process of the DPF, there will be certain residues. As the usage time accumulates, the DPF carrier may become blocked. At this time, it is necessary to disassemble the entire post-processing device and manually clean the DPF carrier.

[0004] The existing patent (publication number: CN220036756U) is a diesel generator set DPF exhaust particulate matter collector, including an air intake chamber, a dust exhaust port, an air intake port and a flap. The air intake chamber is used to achieve natural sedimentation of particulate matter and gather at the bottom of the air intake chamber. When multiple DPF carriers are blocked, emergency pipes can be used for emergency treatment; at the same time, after the DPF carrier is blocked, it does not need to be disassembled, and the recoil airflow is used to reversely clean the impurities. At the same time, a flap is provided at the air intake port to prevent impurities from entering the air intake port and causing secondary pollution of impurities.

[0005] However, the above patent still has certain defects. When the DPF carrier is completely blocked, the pressure increases, and the valve of the emergency pipe needs to be opened manually to clear the exhaust gas to prevent danger, which is not very safe. At the same time, the cleared exhaust gas is directly discharged without filtering, which still causes emission pollution. At the same time, after the particulate matter in the exhaust gas settles in the intake cavity, it is still possible that it is driven into the connecting pipe by the exhaust gas flow and is not effectively filtered out.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] An anti-clogging particle trap that is easy to clean, such as Figures 1 to 4 As shown, it includes an air intake barrel 100, one side of which is fixedly connected to a bottom plate 700, the inner wall of which is fixedly connected to an emergency mechanism 200, the inner wall of which is threadedly connected to a filter element 400, and the outer wall of which is slidably connected to a cleaning mechanism 500; the emergency mechanism 200 includes a first connecting pipe 210 connected to the inner wall of the bottom plate 700, one end of which is fixedly connected to a second connecting pipe 220, the inner wall of which is rotatably connected to a first rotating shaft 230, and the The outer wall of the first rotating shaft 230 located inside the second connecting pipe 220 is fixedly connected to a rotating plate 240, and the outer wall of the rotating plate 240 is rotatably connected to an emergency pipe 270. The outer wall of the first rotating shaft 230 located inside the emergency pipe 270 is fixedly sleeved with a rotating assembly 250, and the interior of the emergency pipe 270 is fixedly connected to an emergency assembly 260; one end of the emergency pipe 270 is fixedly connected to a second DPF carrier connecting pipe 290, and one end of the second connecting pipe 220 is fixedly connected to a first DPF carrier connecting pipe 280, and the second DPF carrier connecting One end of the through pipe 290 is fixedly connected to the air outlet cavity 300, and one end of the first DPF carrier connecting pipe 280 is fixedly connected to the air outlet cavity 300; the rotating assembly 250 includes a first sprocket 251 fixedly sleeved with the outer wall of the first rotating shaft 230, the first sprocket 251 is meshed with a chain 252, the chain 252 is meshed with a second sprocket 253, and the inner wall of the second sprocket 253 is fixedly connected to the emergency assembly 260; the emergency assembly 260 includes a second rotating shaft 261 fixedly connected to the inner wall of the second sprocket 253, and the second One end of the rotating shaft 261 is fixedly connected to the fan 262, the outer wall of the second rotating shaft 261 is rotatably sleeved with a positioning plate 264, one end of the positioning plate 264 is fixedly connected to the third connecting tube 263, the outer wall of the third connecting tube 263 is fixedly connected to the first connecting tube 210, and the outer wall of the third connecting tube 263 is fixedly connected to the emergency tube 270; the inner wall of the emergency tube 270 is fixedly connected to the positioning shaft 265, the outer wall of the positioning shaft 265 is rotatably connected to a baffle 266, and the inner wall of the emergency tube 270 is fixedly connected to a limiting strip 267.

[0028] The exhaust gas enters the air intake barrel 100 through the air inlet on the air intake barrel 100, passes through the filter element 400 (the filter element 400 is fixed on the bottom plate 700 by threaded connection, which is convenient for installation and disassembly), and then enters the first connecting pipe 210 and the emergency pipe 270. The larger particles in the exhaust gas cannot pass through the filter element 400 and fall into the air intake barrel 100. After entering the first connecting pipe 210, the exhaust gas is concentrated through the second connecting pipe 220. The airflow of the exhaust gas drives the rotating plate 240 in the second connecting pipe 220 to rotate around the first rotating shaft 230 as the axis. Thus, the first rotating shaft 230 is driven to rotate, and after passing through the second connecting pipe 220, the exhaust gas enters the first DPF carrier connecting pipe 280 through the first connecting pipe 210, and is filtered by the DPF carrier in the first DPF carrier connecting pipe 280, so that the particulate matter content in the exhaust gas reaches a specified range, and then is discharged through the air outlet cavity 300, wherein the first connecting pipe 210 and the emergency pipe 270 connected to the bottom plate 700 are both located in the filter element 400, so the exhaust gas filtered by the filter element 400 will enter the first connecting pipe 210 and the emergency pipe 270;

[0029] When the first rotating shaft 230 rotates, it drives the first sprocket 251 to rotate, thereby driving the chain 252 to move, and then drives the second sprocket 253 to rotate, and at the same time drives the second rotating shaft 261 to rotate, driving the exhaust gas in the emergency pipe 270 to flow into the third connecting pipe 263, enter the first connecting pipe 210, and then enter the first DPF carrier connecting pipe 280 to be filtered by the DPF carrier;

[0030] When the DPF carrier in the first DPF carrier connecting pipe 280 is blocked, the exhaust gas flow in the first connecting pipe 210 cannot flow, so that the rotating plate 240 cannot drive the first rotating shaft 230 to rotate, and the fan 262 cannot rotate. The airflow of the emergency pipe 270 will not be guided by the fan 262 to the third connecting pipe 263 and then enter the first connecting pipe 210. Instead, the exhaust gas flow in the emergency pipe 270 will push the baffle 266 to rotate around the positioning shaft 265, so that the exhaust gas enters the second DPF carrier connecting pipe 290 from the emergency pipe 270. The DPF carrier in the PF carrier connecting pipe 290 filters the exhaust gas so that the particulate matter content in the exhaust gas reaches a specified range and is then discharged through the air outlet cavity 300. The second DPF carrier connecting pipe 290 serves as a backup DPF carrier. When the DPF carrier in the first DPF carrier connecting pipe 280 is in normal use, the exhaust gas basically does not enter the second DPF carrier connecting pipe 290 through the emergency pipe 270. Optionally, an alarm component is provided in the second DPF carrier connecting pipe 290. When the second DPF carrier connecting pipe 290 is blocked, the alarm component can issue a reminder.

[0031] Please refer to the figure in particular. The cleaning mechanism 500 includes a limiting groove 510 opened on the inner wall of the air inlet barrel 100, and a slider 520 is slidably connected in the limiting groove 510. One end of the slider 520 is fixedly connected to a sliding ring 530, and the inner ring of the sliding ring 530 is fixedly connected to an annular cleaning brush 540, and the annular cleaning brush 540 is slidingly fitted with the filter element 400; a threaded rod 550 is threadedly sleeved on the inner wall of the sliding ring 530, and a handle 560 is fixedly sleeved on the outer wall of the threaded rod 550 located outside the air inlet barrel 100, and four groups of the limiting grooves 510 and the slider 520 are each provided, and the four groups of the limiting grooves 510 and the slider 520 are arranged in a circular array with the filter element 400 as the axis, and the inner wall of the air inlet barrel 100 is connected to a dust suction pipe 600.

[0032] When there are many large particles of impurities filtered out of the air inlet barrel 100 by the filter element 400, the dust suction pipe 600 is opened to connect the dust suction piece, and the dust suction piece is started to suck out the impurity particles in the air inlet barrel 100 to clean the air inlet barrel 100. At the same time, the handle 560 can be rotated to drive the threaded rod 550 to rotate, thereby driving the sliding ring 530 to move. Due to the restriction of the limit groove 510 on the slider 520, the slider 520 and the sliding ring 530 are fixedly connected, and the sliding ring 530 cannot rotate. At the same time, the sliding ring 530 The inner wall connected to the threaded rod 550 is provided with a thread matching the thread of the outer wall of the threaded rod 550. Rotating the threaded rod 550 drives the sliding ring 530 to move along the threaded rod 550, thereby driving the annular cleaning brush 540 to move against the outer wall of the filter element 400, thereby scraping off the impurity particles adsorbed on the filter element 400, cleaning the filter element 400, and preventing the filter holes on the filter element 400 from being blocked, which affects subsequent use. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
