DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-9 As shown, a flue gas purification device for a gas generator set of the present invention comprises a shell 1, in which a generator set is assembled, the shell 1 is provided with a generator set, a control panel 11 is provided on the outside of the shell 1, an exhaust pipe 12 connected to the generator set is provided on the outside of the shell 1, the exhaust pipe 12 is provided with a pressure valve 121, a mounting tube 13 is connected to the exhaust pipe 12 away from the shell 1, the exhaust pipe 12 is connected to the left side of the mounting tube 13, a rotating member 14 is rotatably assembled in the mounting tube 13, a first motor 141 drivingly connected to the rotating member 14 is assembled on the outside of the mounting tube 13, a plurality of partitions 15 are provided on the outer surface of the rotating member 14, the ends and surroundings of the plurality of partitions 15 are slidably sealed and connected to the inner wall of the mounting tube 13, a filter element 16 is arranged between two adjacent partitions 15, a cover plate 17 is provided on the end of the mounting tube 13 away from the exhaust pipe 12, the inner wall of the cover plate 17 is slidably sealed and abutted against the ends of the plurality of partitions 15, the cover plate 17 is provided with an outlet pipe 18 arranged opposite to the exhaust pipe 12, and a discharge port 19 is arranged at the lower side of the mounting tube 13.

[0034] The generator set in the housing 1 starts to work and can generate electricity. The staff controls the operation of the generator set through the control panel 11. During the operation of the generator set, a large amount of exhaust gas will inevitably be generated. These exhaust gases are not only of high temperature, but also contain various particulate matter, such as dust, soot, etc. If they are directly discharged into the atmosphere, it will not only cause environmental pollution, but also affect the normal operation of the generator set;

[0035] In order to effectively treat these exhaust gases, the system has designed an efficient exhaust gas treatment process. First, the exhaust gas will enter the cyclone separator inside the housing 1. The cyclone separator is a cylindrical or conical mechanical separation device that uses the rotation of the airflow to generate centrifugal force to throw large particles in the exhaust gas to the wall and deposit them, thereby achieving preliminary separation. This process can greatly reduce the burden of the subsequent filter element 16, extend the service life of the filter element, and improve the overall filtering effect;

[0036] The temperature of the exhaust gas after the initial treatment by the cyclone separator is still relatively high. In order to prevent the high-temperature exhaust gas from damaging the subsequent filter element 16 and pipeline, the system is equipped with a cooler. The cooler reduces the exhaust gas temperature to a safe range by circulating cooling water or other cooling media to ensure the smooth progress of the subsequent treatment process.

[0037] The exhaust gas can be discharged from the housing 1 through the exhaust pipe 12, and the exhaust gas can be discharged into the installation tube 13 through the exhaust pipe 12. At this time, one of the filter elements 16 of the installation tube 13 matches the position of the exhaust pipe 12. The filter element 16 matching the position of the exhaust pipe 12 is provided with a partition 15 around its periphery; due to the obstruction of the partition 15, the exhaust gas can only pass through the filter element 16 for filtration, and after being filtered by the filter element 16, the exhaust gas is discharged from the outlet pipe 18.

[0038] When the filter element 16 matching the position of the exhaust pipe 12 is clogged, the exhaust gas will not enter other filter elements 16 due to the obstruction of the partition 15. Since the exhaust pipe 12 continues to discharge exhaust gas, and the filter element 16 matching the position is clogged again, the pressure in the exhaust pipe 12 gradually increases. After the pressure valve 121 detects that the pressure in the exhaust pipe 12 reaches a predetermined value, the first motor 141 drives the rotating member 14 to start rotating. The rotating member 14 drives the filter elements 16 to rotate in the installation cylinder 13 through the partitions 15, and a The clogged filter element 16 moves toward the discharge port 19 until the clogged filter element 16 matches the position of the discharge port 19, and the new filter element 16 matches the position of the exhaust pipe 12, and is put into the exhaust gas filtering work again. After the clogged filter element 16 matches the position of the discharge port 19, the clogged filter element 16 is discharged from the discharge port 19. This design can automatically complete the replacement of the filter element 16 after the filter element 16 is clogged, and can continuously ensure the filtration of the exhaust gas generated by the generator set.

[0039] When the staff needs to fill the filter element 16 , the cover plate 17 can be opened to expose the interior of the installation cylinder 13 , and the staff can then add the filter element 16 into the installation cylinder 13 .

[0040] A fixed block 2 is provided on the left side of the mounting cylinder 13, a cavity 21 is provided in the fixed block 2, a slider 22 is slidably mounted in the cavity 21, a plurality of filter elements 16 are provided with linkage components matching the slider 22, a first spring 23 is provided on the side of the slider 22 close to the mounting cylinder 13, a connecting pipe 24 communicating with the cavity 21 is provided on the side of the fixed block 2 away from the mounting cylinder 13, the connecting pipe 24 is connected with a trigger component, and an emergency stop button 25 matching the position of the trigger component is provided on the outside of the shell 1.

[0041] The outer surfaces of the plurality of filter elements 16 are provided with linkage components that match the slider 22. Therefore, when there is a filter element 16 between two adjacent partitions 15 that matches the position of the exhaust pipe 12, the exhaust gas filtering work can be performed normally. The first spring 23 is in a compressed state. When all the filter elements 16 in the installation cylinder 13 are filtered and discharged from the installation cylinder 13 from the discharge port 19, when there is no filter element 16 that matches the position of the exhaust pipe 12, the linkage component starts to work. Under the action of the extension of the first spring 23, the slider 22 is pushed to start moving, and the slider 22 squeezes the gas in the cavity 21 into the connecting pipe 24. The squeezed gas passes through the connecting pipe 24 and enters The trigger component presses the emergency stop button 25 to stop the generator set. This design can monitor the filter element 16 in the installation cylinder 13 without using electrical equipment. When there is no filter element 16 in the installation cylinder 13, the emergency stop button 25 is automatically pressed to stop the generator set to prevent the exhaust gas from being directly discharged to the outside without being filtered, affecting the external air environment. When the filter element 16 matches the position of the exhaust pipe 12 again, the linkage component stops working and drives the slider 22 to reset. The first spring 23 is in a compressed state again, and the slider 22 absorbs the gas pressure entering the connecting pipe 24 back into the cavity 21.

[0042] The trigger assembly includes a mounting block 3 connected to the mounting tube 13, a step hole 31 is provided in the mounting block 3, the connecting pipe 24 is connected to the step hole 31, a top block 32 is slidably assembled in the step hole 31, the top block 32 is provided with a top rod 33 extending out of the step hole 31, a second spring 34 is provided in the step hole 31 and sleeved on the outside of the top rod 33, and the top rod 33 matches the position of the emergency stop button 25.

[0043] When air pressure enters the step hole 31 through the connecting pipe 24, the pressure in the step hole 31 can be increased, pushing the top block 32 to slide in the step hole 31, pushing the top rod 33 out of the step hole 31, pressing the emergency stop button 25, and driving the second spring 34 to compress. When the slider 22 is reset and the gas pressure in the step hole 31 is sucked back through the connecting pipe 24, the negative pressure and the extension of the second spring 34 drive the top rod 33 to retract into the step hole 31, and the top block 32 begins to reset, so the top rod 33 cancels the pressing of the emergency stop button 25.

[0044] A cross bar 35 is disposed outside the top rod 33 , and the end of the cross bar 35 matches the position of the emergency stop button 25 .

[0045] When the top rod 33 drives the cross bar 35 to move toward one side of the shell 1, the emergency stop button 25 is pressed through the cross bar 35. This design can prevent the emergency stop button 25 from being directly located under the top rod 33, making it inconvenient for the staff to press the emergency stop button 25 by hand.

[0046] The inner wall of the cavity 21 near the mounting tube 13 is provided with a pressure relief hole 36 communicating with the outside. The design of the pressure relief hole 36 can balance the stability of the air pressure in the cavity 21.

[0047] The linkage assembly includes a plurality of first arc-shaped magnets 37 and a plurality of second arc-shaped magnets 38. The plurality of first arc-shaped magnets 37 are respectively arranged on the outer surfaces of a plurality of filter elements 16, and the plurality of second arc-shaped magnets 38 are respectively arranged on the outer surfaces of a plurality of partitions 15. A magnetic ring is formed between the plurality of first arc-shaped magnets 37 and the plurality of second arc-shaped magnets 38, and the plurality of first arc-shaped magnets 37 and the plurality of second arc-shaped magnets 38 are all magnetically connected to the slider 22.

[0048] When there are a plurality of filter elements 16 between two adjacent partitions 15, a plurality of first arc-shaped magnets 37 and a plurality of second arc-shaped magnets 38 form a magnetic ring. Therefore, when the first arc-shaped magnet 37 or the second arc-shaped magnet 38 matches the position of the slider 22, the slider 22 can be kept adsorbed to drive the compression of the first spring 23. When there is no filter element 16 that matches the position of the exhaust pipe 12, the adsorption of the slider 22 can be cancelled, so that the slider 22 can slide under the action of the extension of the first spring 23.

[0049] A sealing frame 4 is connected to the lower side of the mounting cylinder 13, and transmission rollers 41 located at the lower side of the discharge port 19 are rotatably installed on the left and right sides of the sealing frame 4, a transmission belt 42 is sleeved between the two transmission rollers 41, and an iron sheet 43 is provided on the outer surface of the transmission belt 42, and a second motor 44 drivingly connected to one of the transmission rollers 41 is provided on the outer side of the sealing frame 4, a dust collecting frame 45 which can be moved out of the sealing frame 4 is provided on the lower side of the transmission belt 42, a plurality of gear levers 46 are provided on the lower side of the transmission belt 42, a discharge port 47 is provided on the left side of the sealing frame 4, and the discharge port 47 is located below the left side of the transmission belt 42, a collecting frame 48 is provided on the lower side of the discharge port 47, and a scraper 49 abutting against the outer surface of the transmission belt 42 is provided on the upper side of the discharge port 47.

[0050] Since one of the transmission rollers 41 is connected to the second motor 44 in transmission, when the second motor 44 starts working, it drives the transmission roller 41 to start rotating. When the transmission roller 41 starts rotating, it drives the transmission belt 42 to start rotating clockwise. When the clogged filter element 16 falls downward from the discharge port 19, its back falls on the outer surface of the transmission belt 42. Since the outer surface of the transmission belt 42 is provided with an iron sheet 43, the first arc-shaped magnet 37 on the outer surface of the filter element 16 is adsorbed on the surface of the iron sheet 43. At this time, the filter element 16 starts to move with the transmission belt 42. The filter element 16 moves with the transmission belt 42. When the filter element 16 is suspended on the dust collecting frame under the action of the transmission belt 42, the filter element 16 is 45, so that the dust attached to the outer surface of the filter element 16 can fall downward into the dust collecting frame 45, and in the process of the movement of the filter element 16, due to the design of the gear lever 46, the filter element 16 collides with the gear lever 46 toward the lower end, in order to move over the gear lever 46, the filter element 16 is deflected, and the cleaning of the dust on the outer surface of the filter element 16 is further improved. When the filter element 16 moves to the upper side of the discharge port 47 under the action of the movement of the conveyor belt 42, the scraper 49 scrapes off the filter element 16 adsorbed on the outer surface of the conveyor belt 42, and the filter element 16 cancels the contact with the conveyor belt 42, and the filter element 16 falls from the discharge port 47 into the collection frame 48, which is convenient for the staff to handle.

[0051] The lower side of the discharge port 19 is provided with an arc plate 5 matching the conveyor belt 42. The design of the arc plate 5 can guide the filter element 16 falling downward, so that the filter element 16 slowly falls on the outer surface of the conveyor belt 42.

[0052] The filter element is composed of multiple layers of filter plates, and the filter apertures of the filter plates gradually decrease from the side close to the exhaust pipe to the side away from the exhaust pipe. This design allows the exhaust gas to first pass through the filter plate with a larger aperture to remove larger particles when passing through the filter element, and then gradually pass through the filter plate with a smaller aperture to remove finer particles. This multi-layer filtration design can effectively improve the purification efficiency of the exhaust gas and extend the service life of the filter element. Because the larger particles are removed first, the burden on the subsequent filter plates can be reduced to avoid premature clogging.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
