One end of the rotating rod 636 on one side is connected through a transmission member 638.
[0048] By setting up the anti-blocking unit 63 and utilizing the contact between the flue gas flow and the blade 637, the rotating rod 636 on one side drives the rotating rod 636 on the other side and the crankshaft 635 to rotate. On the one hand, the connecting rod 634 enables the needle 632 to clean and prevent the air hole 5 from being blocked. On the other hand, the blade 637 on the other side stirs the purification liquid, which not only facilitates the purification of the flue gas, but also facilitates the rapid mixing of material replenishment.
[0049] Embodiment 5: This embodiment is obtained by combining embodiments 1 to 4. By filtering and then purifying the flue gas and overlapping the flow paths up and down, it is convenient to reduce the usage space and improve the purification effect. Liquid water is used for cooling and condensation to achieve heat recovery and avoid evaporation of alkali water.
[0050] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[0051] During operation, the outer end of the smoke inlet pipe 7 is connected to the flue through a flange or other connector, and pure water is injected into the box body 1. Then, the alkali solution for purification is added into the middle flow channel 9 through the feed pipe 14, and then the smoke to be purified enters the filter box 3 through the smoke inlet pipe 7;
[0052] Smoke and dust filtration: After the smoke flows inside the filter box 3, it enters the upper flow channel 9 through the air hole 5. At the same time, the mixed smoke and dust are filtered inside the filter box 3, or directly fall into the dust hood 621, or adhere to the air hole 5. Then the output end of the push-pull rod 67 is repeatedly extended and retracted. Through the traction of the connecting plate 68, the slider 64 slides synchronously along the limit bar 66, and drives the scraper bar 61 to reciprocate, so as to scrape off the attached smoke and dust, so that the smoke can flow smoothly through the air hole 5. The scraped smoke and dust fall into the dust hood 621. Then the vibration motor 623 works to make the dust hood 621 vibrate, so that the internal smoke and dust are collected and fall into the screw extruder 622. Then the screw extruder 622 works to squeeze and discharge the smoke. When the smoke is agglomerated inside the screw extruder 622 When the smoke is completely squeezed into the filter box 3 on the one hand, the sealing plate 624 is pushed to rotate around the axial end of the bracket 625 on the other hand, and the torsion spring 626 is compressed, so that the screw extruder 622 can be reset after being unloaded, and its output end is closed again. After the sealing plate 624 rotates, it is separated from the shielding of the output end of the screw extruder 622, so that the squeezed smoke and dust are discharged. At the same time, when the smoke flows in the upper flow channel 9, it contacts with the blade 637 on one side, so that the rotating rod 636 on one side is driven to rotate. The rotating rod 636 on one side drives the rotating rod 636 on the other side and the crankshaft 635 to rotate synchronously through the transmission member 638. The crankshaft 635 drives the connecting rod 631 to reciprocate through the connecting rod 634, so that the needle 632 follows the movement and repeatedly enters the inside of the air hole 5, thereby clearing the inside of the air hole 5 to avoid being blocked.
[0053] Flue gas purification: When the flue gas flows in the upper flow channel 9, at the same time, the pump body 12 pumps the alkali solution in the middle flow channel 9 into the spray pipe 11, and sprays and purifies the flue gas through the atomizing nozzle. The sprayed alkali solution enters the depression in the upper flow channel 9 and accumulates. When the liquid level reaches a predetermined height, the solenoid valve on the reflux pipe 15 opens, and the flue gas flows back to the middle flow channel 9 through the reflux pipe 15. After preliminary purification, the flue gas enters the middle flow channel 9. Since the alkali solution level in the middle flow channel 9 is higher than the depression below the upper flow channel 9, the flue gas is diverted into the alkali solution for further purification, and then floats out of the alkali solution and passes through After being filtered by the filter cotton, the smoke enters the interior of the lower flow channel 9, and is driven by the booster of the fan 13 and discharged to the outside through the smoke exhaust pipe 10. When the smoke flows in the lower flow channel 9, the concentration sensor monitors the harmful gases in the smoke. If it is not completely purified, it can flow back to the smoke inlet pipe 7 through the circulation pipe for circulation purification to make the exhaust smoke non-toxic and harmless. At the same time, the external feeding equipment adds the raw materials used for purification into the interior of the middle flow channel 9 through the feeding pipe 14, and then stirs through the other side blade 637 for rapid mixing to maintain the concentration of the alkali solution and maintain the purification effect on the smoke.
[0054] Although 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.
