These flue gases often carry a large number of solid particles, such as dust, ash, etc. If directly discharged into the atmosphere, it will not only cause serious environmental pollution but also affect the normal operation and service life of equipment. Therefore, effectively separating and removing particles in high-temperature flue gas is an important link to ensure production efficiency and environmental protection;

[0003] After retrieval, a patent with the Chinese patent publication (announcement) number CN 211189508 U discloses an industrial furnace flue gas particle separation device, including a support, an ash storage tank, an air inlet device, a bright body, a dust removal device, an exhaust device, and a wind shielding device.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Embodiment 1: A high-temperature flue gas particle separation device, as Figures 1 to 4 shown, includes a box body 4. One end of the box body 4 is fixed with an inspection plate 6 by bolts. The top of the box body 4 is welded with a top plate 7. And a cleaning component is rotatably connected to the side wall of the box body 4. One outer wall of the box body 4 is welded with an accommodating rack 16. And a drive motor 15 is fixed to one outer wall of the accommodating rack 16 by bolts. And the output end of the drive motor 15 is fixed with a filter screen 9 by screws. And both ends of the filter screen 9 are arc-shaped;

[0025] By providing a filter screen 9, the box body 4 can be divided into upper and lower two chambers. When it is necessary to separate particles, the high-temperature flue gas first enters the upper chamber. The filter screen 9 can be used to filter and intercept the particles. After the high-temperature flue gas is filtered and intercepted, it passes through the filter screen 9 and enters the lower chamber to achieve particle separation;

[0026] The filtered and intercepted particles will adhere to the upper surface of the filter screen 9. When it is necessary to clean the particles adhering to the filter screen 9, after the filter screen 9 is driven to rotate by the drive motor 15, when the upper surface of the filter screen 9 rotates from above to below, at this time, the filtered and intercepted particles on the filter screen 9 will fall to the bottom of the box body 4 under the action of their own gravity, so as to facilitate the subsequent collection of the particles. At the same time, in order to clean up the small amount of particles that did not fall, the cleaning component can be used to wash the filter screen 9 and its filter holes to ensure the cleaning effect of the filter screen 9;

[0027] By setting the inspection plate 6 and the box body 4 to be detachable, it is convenient to replace or repair the filter screen 9.

[0028] The cleaning component includes an L-shaped plate 11 and a rotating pipe 21. The L-shaped plate 11 is welded to the outer wall of one side of the box body 4, and the rotating pipe 21 is rotatably connected to the inner wall of the through hole formed on the surface of the L-shaped plate 11. One end of the rotating pipe 21 is fixed with a spray pipe 18, and a spray head 19 is welded to the bottom of the spray pipe 18;

[0029] When the filter screen 9 needs to be rinsed, the rotating pipe 21 is connected to the water pump, and the water pump is used to convey water into the rotating pipe 21. Finally, the water is sprayed out through the spray pipe 18 and the spray head 19 to rinse the filter screen 9.

[0030] An installation column 13 is rotatably connected to the outer wall of one side of the box body 4. A belt pulley 17 is fixed to the outer circumference of the installation column 13 and the output end of the driving motor 15 through screws, and a synchronous belt 14 is connected between the two belt pulleys 17. An incomplete gear 20 is fixed to the outer circumference of the installation column 13 through a pin. A complete gear 12 is fixed to the outer circumference of the rotating pipe 21 through a pin, and a torsion spring 10 is clamped between the outer wall of one side of the complete gear 12 and the outer wall of one side of the box body 4;

[0031] By using the transmission of the synchronous belt 14, the driving motor 15 indirectly drives the installation column 13 and the incomplete gear 20 to rotate. The incomplete gear 20 is provided with teeth in a partial area. When the teeth on the incomplete gear 20 mesh with the complete gear 12, the rotating pipe 21, the spray pipe 18 and the spray head 19 are driven to swing by a certain angle, which can increase the spraying range of the spray head 19 and avoid dead corners when the filter screen 9 is rinsed;

[0032] When the teeth on the incomplete gear 20 are disengaged from the complete gear 12, at this time, the complete gear 12 and the rotating pipe 21 are reset under the resilience of the torsion spring 10, so that the spray pipe 18 and the spray head 19 return to the initial state. In this way, the spray pipe 18 and the spray head 19 can swing periodically to ensure the rinsing effect on the filter screen 9.

[0033] An air inlet valve 5 and an exhaust valve 3 are respectively fixed to the outer wall of the box body 4 through bolts, and the air inlet valve 5 is located above the exhaust valve 3;

[0034] By providing the air inlet valve 5, the high-temperature flue gas to be separated can be introduced into the box body 4, and the filtered high-temperature flue gas can be discharged by using the exhaust valve 3.

[0035] Vertical plates 2 are respectively fixed to the outer walls on both sides of the box body 4 through bolts, and a base 1 is welded to the bottoms of the two vertical plates 2;

[0036] By providing the base 1 and the vertical plates 2, the box body 4 can be supported.

[0037] A drain valve 8 is fixed to the bottom of the box body 4 through bolts;

[0038] When the drain valve 8 is opened, the waste liquid after flushing can be discharged to avoid the accumulation of waste liquid at the bottom of the box body 4.

[0039] Working principle: After the device is started, the high-temperature flue gas is introduced into the upper chamber of the box body 4 through the intake valve 5. When the high-temperature flue gas passes through the filter screen 9, the particles are intercepted by the filter screen 9, and the filtered high-temperature flue gas finally discharges through the exhaust valve 3. The intercepted particulate matter gradually accumulates on the upper surface of the filter screen 9. When the particles accumulated on the filter screen 9 reach a certain degree and need to be cleaned, the drive motor 15 drives the filter screen 9 to rotate. During the rotation of the filter screen 9, the particulate matter on its upper surface falls into the lower chamber of the box body 4 under the action of its own gravity. While the filter screen 9 rotates, the spraying assembly starts to work. The water pump transports water into the rotating pipe 21, and then the water sprays out through the spray pipe 18 and the nozzle 19 to wash the filter screen 9. The synchronous belt 14 drives the drive motor 15 to indirectly drive the mounting post 13 and the incomplete gear 20 to rotate. When the tooth of the incomplete gear 20 meshes with the complete gear 12, the rotating pipe 21, the spray pipe 18 and the nozzle 19 are driven to swing by a certain angle to expand the spraying range and avoid flushing dead angles. When the incomplete gear 20 disengages from the complete gear 12, the complete gear 12 and the rotating pipe 21 reset under the resilience of the coil spring 10, so that the spray pipe 18 and the nozzle 19 return to the initial state. This process is repeated periodically to ensure that the filter screen 9 is comprehensively and effectively washed. The waste liquid after flushing accumulates at the bottom of the box body 4. When the waste liquid needs to be discharged, the drain valve 8 is opened, and the waste liquid can be discharged from the device.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
