Background

The boiler is one of the important power equipment of industrial production, and the flue gas in the stove carries a large amount of dust, adsorbs easily on the tubulation inner wall in the stove, because the temperature is high in the stove, leads to that the dirt that adsorbs at the tubulation inner wall is harder, is difficult for the mediation. And because the smoke gas volume is large, dust and dirt adsorbed in the tube array of the furnace can block the tube array within 1-2 days, which brings inconvenience to normal production. After the tubulation blocks up, generally use the mode of manual work clearance to clear up, but the mode of manual work mediation has a lot of drawbacks: 1. the labor intensity of personnel is high; 2. personnel labor cost is high; 3. safety accidents are easily caused: firstly, in the dredging process, part of smoke leaks, operators can inhale the smoke carelessly, the operators can suffer from occupational diseases for a long time if the smoke leaks, and the operators are coma and dead due to the fact that the operators inhale excessive toxic and harmful gases if the smoke leaks. Secondly, the temperature in the furnace is higher (higher than 1300 ℃), and the dredging tool (steel pipe) in the hand of the operator enters the furnace, so that the dredging tool has higher temperature, and the operator is easily scalded.

Similarly, a large amount of smoke dust is carried in smelting smoke of a metallurgical smoke pipeline and is easily adsorbed on the inner wall of a flue pipe, dust and dirt adsorbed on the inner wall are hard and are not easy to dredge due to the high smoke temperature of a smoke pipe, the dust and dirt adsorbed in the inner pipe can block the pipeline by half in a period of time, so that the resistance of the smoke pipe is increased, the energy consumption is increased, the smoke amount is reduced, and inconvenience is brought to normal production. When the smoke tube is blocked, the smoke tube is cleaned by manual cleaning, and the problems and the disadvantages are also caused.
