DETAILED DESCRIPTION

[0026] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: an exhaust gas filtering treatment device for a power plant which is easy to clean, comprising: an exhaust gas filtering body 1, a high-pressure spray head 2, a slide rail 3, a filter material placement rack 4, a first rotating rod 5, a mounting block 6, a cleaning plate 7, a first gear 8, a second rotating rod 9, a second gear 10, a rotating guide rail 11, a first motor 12, a guide rod 13, a bidirectional threaded rod 14, an internal threaded sleeve block 15, a cleaning scraper 16, and a second motor 17.

[0028] First, as attached Figure 1 , Attachment Figure 3 and attached Figure 5 As shown in , when the exhaust gas filter device is filtering the exhaust gas from the power plant, the filter material placement rack 4 is blocked during long-term use, thereby reducing the filtering performance. Then, the first motor 12 can be started, and the guide rod 13 can be driven to rotate through the output end of the first motor 12. Since the guide rod 13 is in an "L"-shaped structure and is slidably connected with the rotating guide rail 11, the first motor 12 drives the guide rod 13 to rotate inside the rotating guide rail 11, and at the same time, the rotating guide rail 11 drives the second rotating rod 9 to rotate, so that the second rotating rod 9 also drives the second gear 10 to rotate, and then the second gear 10 is meshed with the first gear 8 in a semi-arc structure, so that the first gear 8 drives the first rotating rod 5 to rotate on the side wall of the exhaust gas filter body 1, so that the first rotating rod 5 drives the cleaning plates 7 at the upper and lower ends of the mounting block 6 to rotate. Since the cleaning plates 7 rotate on the left and right ends of the filter material placement rack 4, the cleaning plates 7 are rotated up and down to clean the side walls of the filter material placement rack 4, thereby cleaning the dirt and particulate matter on the surface of the filter material placement rack 4;

[0029] As attached Figure 1 and attached Figure 4As shown in, after the dirt and particulate matter on the surface of the filter material placement rack 4 is cleaned, dirt and particulate matter are also left on the parts inside the exhaust gas filter body 1, and then the high-pressure spray heads 2 fixedly installed on the left and right ends of the top of the exhaust gas filter body 1 are used, and the high-pressure spray heads 2 are symmetrically arranged front and back about the vertical center axis of the exhaust gas filter body 1, and then the high-pressure spray heads 2 are connected to the external water source, so that the high-pressure spray heads 2 can flush the internal parts of the exhaust gas filter body 1 and the filter material placement rack 4. After flushing the dirt and particulate matter remaining on the internal parts of the exhaust gas filter body 1 and the filter material placement rack 4 is completed, the second motor 17 can be started, and then the output end of the second motor 17 drives the bidirectional thread The rod 14 rotates at the inner bottom of the exhaust gas filter body 1. Since the inner side wall of the internal threaded sleeve 15 is connected to the bidirectional threaded rod 14 through threads, the left internal threaded sleeve 15 in the bidirectional threaded rod 14 and the right internal threaded sleeve 15 in the bidirectional threaded rod 14 slide in opposite directions, so that the internal threaded sleeve 15 drives the cleaning scraper 16 to slide in opposite directions. Since the side wall of the cleaning scraper 16 is in an inclined state and fits with the bottom of the exhaust gas filter body 1, the cleaning scraper 16 cleans the accumulated dirt into the through groove, and then the cleaning scraper 16 can clean the accumulated residual dirt and particulate matter at the bottom of the exhaust gas filter body 1, thereby keeping the interior of the exhaust gas filter body 1 clean and tidy, and thus maintaining the flowability of the exhaust gas filter body 1;

[0030] As attached Figure 1 and attached Figure 3 As shown in the figure, when the filter material placement rack 4 is used for a long time, it causes the aging of the filter material placement rack 4, and then the door on the exhaust gas filter body 1 can be opened, and the bidirectional threaded rod 14 can be removed from the interior of the exhaust gas filter body 1, and then the filter material placement rack 4 is pulled in turn, so that the filter material placement rack 4 slides inside the slide rail 3, and then the filter material placement rack 4 is taken out from the interior of the exhaust gas filter body 1, and then the filter material placement rack 4 that needs to be replaced is replaced, and then the replaced filter material placement rack 4 is inserted into the interior of the slide rail 3 again, so that the filter material placement rack 4 is fitted with the slide rail 3, and then the filter material placement rack 4 slides to the specified position inside the slide rail 3, thereby completing the replacement of the filter material placement rack 4, and then improving the filtering performance.
