Therefore, it is necessary to filter out the solid particulate matter in the silicon carbide high-temperature gas through a breathable filter plate. However, the solid particulate matter in the silicon carbide high-temperature flue gas is easily attached to one side of the breathable filter plate and the inner wall of the flue gas treatment device due to the filtration of the breathable filter plate. Over a long period of time, the solid particulate matter attached and accumulated on the breathable filter plate and the inner wall of the flue gas treatment device is easy to affect the normal working effect of the silicon carbide high-temperature flue gas treatment device and reduce the usable volume of the internal space of the silicon carbide high-temperature flue gas treatment device.

[0020] A silicon carbide high-temperature flue gas treatment device comprises a tank body 1, an exhaust pipe 2, a smoke inlet pipe 3, a slag discharge pipe 4 and a support leg 5, the exhaust pipe 2 is fixedly connected to the outside of the tank body 1, the smoke inlet pipe 3 is connected through the inside of the tank body 1, the slag discharge pipe 4 is connected through the inside of the tank body 1, the support leg 5 is fixedly connected to the outside of the tank body 1, the fixing frame 6 is fixedly connected to the outside of the supporting leg 5, the inside of the fixing frame 6 is fixedly connected to a motor 7, the end of the main shaft of the motor 7 is fixedly connected to a rotating shaft 8, the outside of the rotating shaft 8 is fixedly connected to a bearing 9, the inside of the rotating shaft 8 is fixedly connected to a first curved plate 10, the side of the first curved plate 10 away from the motor 7 is fixedly connected to an oblique scraping rod 11, the other end of the oblique scraping rod 11 is fixedly connected to a second curved plate 12, the inside of the tank body 1 is fixedly connected to a grid plate 13, and the side of the grid plate 13 close to the motor 7 is fixedly connected to a filter membrane 14.

[0021] The cross-sections of the first curved plate 10 and the second curved plate 12 are "S"-shaped. The first curved plate 10 and the second curved plate 12 are on the same axis. The second curved plate 12 is fixedly connected to the other end of the rotating shaft 8, which is convenient for scraping off the filter membrane 14 and the silicon carbide high-temperature flue gas solid particulate matter attached to the inner wall of the tank body 1; the side of the second curved plate 12 away from the motor 7 is in close contact with the filter membrane 14, and the side of the first curved plate 10 close to the motor 7 is in close contact with the bottom end of the inner wall of the tank body 1. The first curved plate 10 and the second curved plate 12 are both in close contact with the inner wall of the tank body 1, so that the substances attached to the filter membrane 14 and the inner wall of the tank body 1 can be scraped and cleaned. To ensure the air permeability of the filter membrane 14 and the space volume inside the tank body 1; there are a total of 2 oblique scraper rods 11, and the oblique scraper rods 11 are rotated 180° with the axis of the rotating shaft 8 as the center of the circle, and the oblique scraper rods 11 are all in close contact with the inner wall of the tank body 1, and can connect the first curved plate 10 and the second curved plate 12, and are convenient for scraping and cleaning the inner wall of the tank body 1; the height of the second curved plate 12 is greater than or equal to the diameter height of the slag discharge pipe 4 on the inner side of the tank body 1, and the second curved plate 12 is close to the motor 7 and is in close contact with the bearing 9, so that the solid particulate matter of silicon carbide high-temperature flue gas that falls into the bottom of the tank body 1 is pushed out from the slag discharge pipe 4.

[0022] Working process: During use, the equipment is powered by an external power supply. When the high-temperature flue gas treatment device is used to treat silicon carbide high-temperature flue gas, the silicon carbide high-temperature flue gas enters the inner side of the tank body 1 through the smoke inlet pipe 3, and under the pressure of the silicon carbide high-temperature flue gas continuously input into the tank body 1, the silicon carbide high-temperature flue gas is transported and moved toward the exhaust pipe 2 connected to the tank body 1. In this process, the silicon carbide high-temperature flue gas passes through the filter membrane 14 and the mesh plate 13, and the gas in the flue gas can pass through the filter membrane 14 and the mesh plate 13 smoothly, but the solid particulate matter in the flue gas is filtered by the filter membrane. 14 intercepts and adheres to the outside of the filter membrane 14 and the inner wall of the tank body 1 below the filter membrane 14. At this time, the motor 7 on the outside of the tank body 1 can be started. The motor 7 drives the rotating shaft 8 fixedly connected to its main shaft to rotate inside the tank body 1 through the bearing 9 with a sealing function. During the rotation of the rotating shaft 8, the first curved plate 10 and the second curved plate 12 fixedly connected thereto are simultaneously driven to rotate toward the outer arc direction of the two curved plates, so that the second curved plate 12 can scrape off the silicon carbide high-temperature flue gas solid particles attached to the filter membrane 14 and make them fall to the bottom of the tank body 1. At the same time, the first curved plate 10 and the second curved plate 12 are fixedly connected by the oblique scraping rod 11. Since the first curved plate 10 and the second curved plate 12 are spatially rotated and misaligned, the upper end of the oblique scraping rod 11 connecting the first curved plate 10 and the second curved plate 12 is inclined toward the rotation direction of the second curved plate 12, so that the oblique scraping rod 11 can scrape off the silicon carbide high-temperature flue gas solid particles attached to the inner wall of the tank body 1 and make them fall to the bottom of the tank body 1, so that the first curved plate 10 rotating with the rotating shaft 8 can scrape off the silicon carbide high-temperature flue gas solid particles that fall on the bottom of the tank body 1. The solid particles of silicon carbide high-temperature flue gas at the bottom of the tank body 1 are scraped and gathered, and the silicon carbide high-temperature flue gas solid particles at the bottom of the tank body 1 are pushed to a position close to the inner wall of the tank body 1 through one side of its outer arc, so that the silicon carbide high-temperature flue gas solid particles at the bottom of the tank body 1 can be passively discharged from the slag discharge pipe 4 connected to the tank body 1, and then enter the inner side of the external sealed box or barrel connected to the slag discharge pipe 4. This device effectively avoids the solid particulate matter adhering to and accumulating on the air permeable filter plate and the inner wall of the flue gas treatment device, affecting the normal working effect of the silicon carbide high-temperature flue gas treatment device, and maintaining the internal space usage volume of the silicon carbide high-temperature flue gas treatment device.

[0023] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
