When the push rod 48 moves, it drives the movable rod 50 to move in the direction of the trigger 51. When the push rod 48 drives the gate plate 49 to move to the maximum amplitude, the flow rate of the spray liquid increases to the maximum. At this time, the movable rod 50 contacts the trigger 51, so that the electric regulating valve 21 is closed, and the exhaust gas output pipe 25 is closed to prevent high-temperature gas from continuously entering the interior of the main body 1, so that the temperature inside the main body 1 stops rising, and the interior of the main body 1 is prevented from being damaged when the temperature is too high, thereby realizing overheating protection for the main body 1.

[0031] Working principle: the exhaust gas flows into the dust collecting bin 22 along the exhaust gas inlet pipe 23. At this time, the discharge electrode 26 and the dust collecting plate 27 in the dust collecting bin 22 are energized, so that an electric field is formed between the dust collecting plate 27 and the discharge electrode 26. When the exhaust gas flows through the electric field, the dust and impurities inside are adsorbed to the surface of the dust collecting plate 27. The gas after dust removal flows into the inside of the main body 1 through the exhaust gas outlet pipe 25, generating thrust on the turbine blades 15, so that the turbine blades 15 start to rotate. When collecting dust, the motor 31 is started, so that the conveying shaft 32 starts to rotate. When the conveying shaft 32 rotates, it drives the driving bevel gear 35 to start rotating, so that the driven bevel gear 36 meshing with the driving bevel gear 35 starts to rotate. When the driven bevel gear 36 rotates, it drives the driven shaft 37 at the top to start rotating, so that the driving wheel 38 at the top of the driven shaft 37 starts to rotate, and when the driving wheel 38 rotates, it drives the first residual The gear 39 starts to rotate, and at the same time, the driven wheel 44 meshing with the driving wheel 38 is driven to rotate synchronously through the transmission belt 43, so that the second residual gear 45 on the top of the driven wheel 44 rotates accordingly. When the first residual gear 39 and the second residual gear 45 rotate, they drive the sliding rack 40 inside thereof to perform horizontal reciprocating motion, thereby driving the connecting rod 41 at the top of the sliding rack 40 to perform horizontal reciprocating motion between the dust collecting plates 27, so that the cleaning rods 42 at both ends of the connecting rod 41 perform horizontal reciprocating motion on the surface of the dust collecting plates 27, thereby collecting the dust adsorbed on the surface of the dust collecting plates 27, so that it falls into the inside of the dust collecting groove 28 along the groove, and when the conveying shaft rotates, it drives the spiral blade 33 to start rotating, and the dust inside the conveying cylinder 30 is conveyed outward, and finally discharged along the dust exhaust port, thereby realizing the automatic collection of dust in the exhaust gas and avoiding the blockage of the pipeline inside the quenching tower.

[0032] When the turbine blades 15 rotate, the rotating shaft 14 is driven to start rotating, and when the rotating shaft 14 rotates, the cross bar 16 is driven to start rotating, so that the scraper 17 at the other end of the cross bar 16 starts to rotate. When spraying, the liquid pump 6 is started, so that the spray liquid flows into the inside of the annular diverter pipe 9 along the spray liquid delivery pipe 7, and then sprays out along the nozzle 10, so that the spray liquid is fully in contact with the high-temperature gas inside the main body 1, and the high-temperature gas is quickly cooled. At this time, the temperature inside the main body 1 increases, causing the thermal sensitive liquid to expand due to the heat, pushing the piston 46 to move toward the inner end of the piston chamber 20. When the scraper 17 rotates, the mixed solution of the spray liquid and the gas on the inner wall surface of the main body 1 is scraped off to prevent the inner wall of the main body 1 from being corroded.

[0033] When the piston moves, the spring 47 is compressed, generating an elastic force in the opposite direction, and driving the push rod 48 to move accordingly. When the push rod 48 moves, it drives the gate plate 49 inside the gate valve 8 to move toward the direction of the main body 1, so that the liquid flow area inside the spray liquid delivery pipe 7 is increased, thereby increasing the flow rate of the spray liquid. When the temperature inside the main body 1 is higher, the expansion amplitude of the thermosensitive liquid is greater, so that the amplitude of the movement of the piston 46 is greater, the amplitude of the movement of the gate plate 49 driven by the push rod 48 is greater, and the flow rate of the thermosensitive liquid is greater, thereby realizing self-regulation of the flow rate of the thermosensitive liquid, so that the temperature inside the main body 1 remains stable. When the push rod 48 moves, it drives the movable rod 50 to move in the direction of the trigger 51. When the push rod 48 drives the gate plate 49 to move to the maximum amplitude, the flow rate of the spray liquid increases to the maximum. At this time, the movable rod 50 contacts the trigger 51, so that the electric regulating valve 21 is closed, and the exhaust gas output pipe 25 is closed to prevent high-temperature gas from continuously entering the interior of the main body 1, so that the temperature inside the main body 1 stops rising, and the interior of the main body 1 is prevented from being damaged when the temperature is too high, thereby realizing overheating protection of the main body 1.

Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
