the third group is a high-temperature cleaning nozzle, a cleaning nozzle is additionally arranged in the radial direction of the cold end of the air side area, and high-pressure steam with the temperature of 300 ℃ is used for cleaning in the nozzle to further raise the ammonium bisulfate.
In this case, a third group of improvements is mainly further optimized, wherein the first advantageous point of the invention is illustrated below:
before the work begins, as shown in fig. 4 and 6, a candle is stored at the top end of the candle oil pipe 4, the volume of the solid candle is larger than the diameter of the middle through pipe of the candle oil pipe 4, and the candle solid cannot fall to the lower end of the candle oil pipe 4;
when the candle oil cleaning device starts working, as shown in fig. 2, a high-temperature cleaning nozzle arranged in the radial direction of the cold end of the air side area starts to clean with high-pressure water vapor, and in the cleaning process, due to the action of overhigh temperature, the solid candle stored at the top end of the candle oil pipe 4 starts to melt (the high-pressure water vapor in the nozzle is 300 ℃, the candle starts to melt at 40 ℃, and the candle starts to become fluid at 70 ℃), the candle liquid fluid enters the lower end through a middle through pipe of the candle oil pipe 4, and along with the gradual increase of the volume of the candle liquid fluid, as shown in fig. 5 and 7, the candle liquid fluid starts to press the oil pressure plate 44 to move downwards, through the arrangement of the leakage-proof gasket 7, the candle liquid fluid is ensured not to enter the lower end of the oil pressure plate 44 from a connecting gap between the oil pressure plate 44 and the candle oil pipe 4, as shown in fig. 3 and 8, because the pressure-reducing frame 45 slides with the side wall of the air cold end pipe 2, and the connecting rod 3 has a supporting effect on the whole candle oil pipe 4, along with the downward pressing of the oil pressure plate 44, the pressure drop frame 45 moves downwards at the same time, so that the slope end of the pressure drop frame starts to act on the ammonium bisulfate on the inner side of the tube wall in a matching manner with high-temperature steam, and the function of cleaning a push shovel is achieved;
after the work is finished, as shown in fig. 5, as the cooling of the whole device is carried out, the candle liquid fluid is re-solidified at the lower end of the candle oil pipe 4, at this time, the oil pipe upper cover 41 and the oil pipe lower cover 42 are rotated until the candle oil pipe 4 and the oil pipe upper cover are separated, the pressure reduction frame 45 is manually pressed down, due to the movable connection of the candle oil pipe 4 and the connecting rod 3, the lower end of the candle oil pipe 4 is wrapped by the other hand to avoid the candle falling off, at this time, the candle oil pipe 4 is rotated for 180 degrees, the lower end of the candle oil pipe 4 is turned to the upper end, the pressure reduction frame 45 is slowly loosened, one hand continues to grasp the upper end of the candle oil pipe 4, the other hand starts to perform the screwing process of the oil pipe lower cover 42 and the oil pipe upper cover 41, so that the solidification and melting characteristics of the candle are utilized to reduce the energy consumption, wherein the setting of the abutting groove 8 realizes the function of convenient rotation during the rotation, as shown in fig. 8;

The second advantageous point of the present invention is explained by the following:
when the work starts, as shown in fig. 3, along with the ejection of high-pressure steam, under the action of high-pressure air outlet, the plurality of rotating fan blades 52 start to rotate, so that the function of turning the wind direction is achieved, at the moment, under the action of high-temperature steam, ammonium bisulfate or sticky impurities pushed and shoveled at the slope end of the pressure drop frame 45 can be acted by the wind force, the diffusion of high-temperature water molecules is accelerated by the action of the wind force, so that the decomposition effect of the ammonium bisulfate is promoted, and meanwhile, the shoveling surface of the pressure drop frame 45 is cleaned;
in conclusion, the pneumatic cleaning device and the high-temperature steam are matched, the wind power steering function of the pneumatic cleaning device is utilized under the high-temperature condition, the molecular diffusion movement of the shovel surface end is accelerated, the decomposition rate of ammonium bisulfate is accelerated, and meanwhile, the blowing cleaning of the sticky impurities on the shovel surface is realized by utilizing the wind power.
